1. GENERAL
This instruction describes the Kiosk No. 8 the preparation of the site, the transportation to and the erection of the kiosk on the site and the installation of the lighting and telephone apparatus.

It is important that arrangements shall have been made will all concerned, including the electricity authority, for the preliminary work to be performed in accordance with a pre-determined programme.

Such a programme should ensure that arrangements are made for:-

1. The preparation of the site and leading in of the telephone cable.
    

2. Earthing arrangements.
    

3. The availability of the electricity supply service lead.
    

4. The availability of the telephone cable pair.
    

5. The fitting of the electric lighting equipment.
    

6. The fitting of the telephone apparatus.
    

7. The exchange termination and jumpering.
    

8. The preparation of notices, dial label and directories.

These arrangements should enable telephone service to be available from the kiosk as soon as the kiosk erection work is completed or otherwise at the earliest opportunity.

2. DESCRIPTION OF THE KIOSK No. 8
The kiosk, which is assembled glazed and painted at the manufacturers works, comprises six cast iron parts and an aluminium door, as scheduled in Table 1 which also shows approximate weights of these items. Table 2 shows approximate weights of the kiosk assembled and with telephone apparatus fitted.

TABLE 1

TABLE 2

The bottom of the sill of the kiosk stands at ground level onto a previously laid concrete base to which it is bolted using four stainless steel or bronze sockets cast into the base at the time of laying. Four 1" diameter holes will need to be drilled in the kiosk sill for these bolts until Kiosks No. 8 are provided already drilled. Four levelling screws are fitted in the sill of the kiosk to facilitate vertical alignment. The sill is filled with aggregate which is then covered with a concrete slab to form the floor inside the kiosk. This arrangement will provide a firm floor straight away and thus enable the kiosk to be working by the time the erection party leave. This will necessitate procedures which are outlined in this TI.

The Kiosk shown pictures to the right is a Mark 2.

The solid cast iron back panel has bosses cast on to provide secure fixing points for the wallboards, earthing terminal and various types of coinbox telephone. These bosses are drilled and tapped at the manufacturers works. All tapped holes are of ISO-metric sizes and screws for use with the kiosk to fit the internal apparatus, with the exception of the power equipment, are in a bag. These screws are listed in Table 3 and should be given to the person who is to fit out the kiosk with the internal equipment. (Screws for the associated power equipment are provided with the power equipment.)

The two sides and door are each glazed with a large rectangular sheet of toughened glass secured by putty and aluminium glazing beads. These beads are secured by screws and are removable to facilitate the replacement of broken glass. These screws are available for replacement purposes from Supplies Division and are known as Screws M4 x 16 mm Slotted CSK Hd, mild steel, sherardized and passivated.

The side and back panels are bolted to the Roof Ring, at the top, and to the sill, at the bottom. They are also bolted to each other at points of one third and two thirds along the vertical sides of these panels. The roof ring, also provides a secure fixing for the door closer mechanism.

The four sides of the roof dome are glazed with small rectangular panes of toughened glass each of which bears the legend "TELEPHONE". These glasses are secured with putty and spring type glazing clips. The dome laps over the roof ring to provide slots for ventilation.

Fluorescent lighting is provided in the dome and is normally switched on permanently.

The kiosk may be ordered as Kiosk No. 8A, 8B, 8C or 8D which are alternative assemblies to give a left hand or right hand opening door with the back panel on the side or rear.

TABLE 3

5. TRANSPORT AND HANDLING OF KIOSK AT AREA STORAGE POINT
The kiosks are delivered to specified depots in the various telephone areas assembled, glazed and painted. They are transported horizontally from the manufacturers works. They should be unloaded, turned from the horizontal to the vertical position and stored ready for fitting out and/or collection by the kiosk trailer in accordance with TI M4 E0099.

6. KIOSK APPROACH
When the approach to the kiosk is across soft ground or grass verges, a path of concrete or similar suitable material shall be provided to the nearest firm pathway. Unless the local authority offer to provide a foot-path, the Area should obtain their agreement for a footpath during siting negotiations. When a concrete path is to be constructed it should be as wide as the kiosk foundation (3' 2") for a distance of 4' from the kiosk door. If the path is to be longer than 4' it may then narrow off to 2' 6" wide. It should be approximately 2" thick.

When a kiosk is to be provided on sloping ground it may be necessary to provide a step to give ease of entrance to the kiosk. The step should be sited a safe distance from the kiosk door so that the door can be opened with ease and without danger whilst standing on the step.

The approach and any step should be made from 'F' quality concrete as described in TI A2 G0051 and laid at the same time as the kiosk foundation.

7. FOUNDATION, DUCTS, EARTHING AND LEAD-IN-CABLE
The foundation for the kiosk, the trenching, the cutting, the telephone cable and earthing requirements should be provided in a single visit whenever possible. This paragraph describes that part of the work. Should the site selected be covered with paving stones, they should be removed and reinstated around the kiosk foundation as described in TI A2 D0125.

1. Planning work should have been made in advance of the arrival of the excavation and foundation unit so that there will be no difficulty in recognising the position for the kiosk site, the ducting and the run for the telephone cable and the exit point for the ducting for the electricity authority cable. This information should be provided in diagram form to the staff that are to carry out the work, and should also be adequately marked on site. The diagram should also show any approach required to the kiosk and the position of any steps.
    

2. As stated earlier the kiosk is to be bolted down to the foundation with stainless steel bolts screwed into stainless steel or Bronze sockets that are cast into the foundation at the time of its laying. The stainless steel or Bronze sockets and stainless steel bolts and washers are known as Anchors No. 2A.
    

3. To position the anchors correctly into the foundation they must be fitted to a framework. This framework which should be made locally, also has two holes for locating the two ducts described in (d). The framework is designed to lay across the excavation of the kiosk foundation. The Anchors No. 2A should be fitted to the framework so that the socket parts of the anchors will be embedded into the concrete. These should be fitted to the framework prior to or whilst the excavation is in progress, in readiness.
    

4. The electricity authority runs the electricity cable required for the kiosk lighting and they should have been consulted well in advance as to the method they are to use to lead the cable in and the position, so that suitable provision for entry can be made whilst the foundation is being laid. Duct No. 56 should be installed for this cable and must be continuous right through from below and beyond the foundation concrete, to just above the final floor level inside the kiosk, in order to prevent gas leakage into the kiosk sill. The ducts are required to emerge close to the back panel of the kiosk and the Duct No. 56 should be angled; any join must be below the concrete and sealed off.

   Drawing P/EL 878 shows the electrical arrangements for a Kiosk No. 8 including how to provide the correct angle on the Duct No. 56.
    

5. The excavation for the telephone cable ducting should be in accordance with TI A2 F0322. The excavation for the kiosk foundation should be 3' 2" square x 7" deep. The excavation for the telephone cable should make a good run up to this site and the ducting laid in so that it will be continuous without break from where the armouring of the lead-in-cable is separated, beyond the kiosk for earthing purposes through the concrete base up to just above the final floor level inside the kiosk to prevent gas leakage into the sill.
    

6. When the excavation for the foundation and cabling has been made and the ducting placed satisfactorily, the telephone ducting trench should be refilled, up to the end of the duct. Whilst this is going on the framework with the Anchors No. 2A fitted to it should be laid across the foundation excavation so that it is supported either side by firm soil or boards. It should lie level as far as it is possible. This will help as a levelling guide for the concrete. As it is being positioned the ducts should be passed through the holes in the framework. to locate them correctly. It must be remembered that these ducts should have been positioned adjacent to the position that the back panel of the kiosk will take up.
    

7. Concrete - The excavation for the foundation should be filled with 'F' quality concrete which must be mixed laid and protected in accordance with TI A2 G0051. The concrete must be carefully puddled around the socket of each Anchor No. 2A up to the level where the bolt enters the socket and around the two ducts. The excavation should be filled with the concrete up to the underside of the lowest member of the framework and smoothed off level. A concrete approach. if required, and any step or other associated concrete work should be laid at the same time.
   
   The earth electrodes should be provided in the cable trench in accordance with TI A2 E1002. The lead-in-cable, Cable Polythene Twin No. 3 should be placed in the Duct No. 100 so that approximately 5' 6" of the cable will extend above the exit from the conduit into the kiosk. At the other end of this cable the armouring should be joined to the earth electrodes in accordance with TI A2 H2605. The trench should then be filled in and made good.
    

8. When necessary a drainage channel should be provided in the surface of the kiosk foundation to take excess rain water away from the kiosk.
    

9. The concrete should be allowed to set for 5 days before the kiosk is erected on the site.
    
10. The site should be provided with guards as seen necessary,

8. PREPARING CONCRETE SLAB FOR THE KIOSK FLOOR
The concrete slab should be made or obtained locally and of dimensions 29" x 24" (737mm x 610mm) using 'F' quality concrete in accordance with TI A2 G0051.

To make the slab. construct a framework of wood 2" x 2" (with sides screwed together) so that the internal dimensions are 29" x 24" and ensure that the corners are square and the sides straight. Lay this framework with the concrete mix and level off to the top of the framework.

After 5 days the slab may be removed by unscrewing the sides of the frame-work. By making a larger sectional framework many slabs can be made at the same time.

Alternatively arrangements can be made locally to have them produced by a suitable manufacturer.

9. DRILLING THE KIOSK SILL
Four, l" holes are required in the sill of the kiosk by which means it is bolted to the kiosk foundation. The kiosk will be provided with eight pre-drilled holes, the four holes on the sides adjacent to the back panel shall be used e.g. the four holes shall be used when siting a Kiosk No. 8 types A and B. Until the kiosk are provided with the holes already drilled, the four holes required will have to be drilled locally.

10. FITTING OUT OF KIOSK BEFORE TRANSPORT TO SITE

1. So that the kiosk can be working when the erection team leave, local organisation should be such that one member of the team can connect the coinbox telephone on site and test it to see if it is working. To achieve this, it will be necessary for the internal equipment to have been fitted into the kiosk including the connection of earthing wires to the back panel of the kiosk.
    

2. The connection of the earth wires should be prepared by twisting together 3 lengths of Wire Earthing 9142/1W Grey, stripping the ends and soldering these with another length of Wire Earthing 9142/1W Grey into a Socket Soldering Type 1, 8D.
   
   The 3 twisted lengths are for joining to the armouring of the telephone lead-in-cable, Cable Polythene Twin No. 3. The armouring of this cable acts as the earth conductor of the lead-in-cable and should be correctly earthed at the distant end. The remaining length of Wire Earthing 9142/1W Grey is for connecting to the earthing terminal inside the coinbox telephone (Kit No. 176A).
   
   The Socket Soldering Type 1, 8D should be bolted to the earth boss on the kiosk back panel in such a way that the armouring from the telephone lead-in-cable can be soldered to the 3 twisted lengths of Wire Earthing 9142/1W Grey at a point above the lower wallboard. It is intended that, on site, the lead-in-cable will be brought up to the left hand side of the Kit No. 176A and the armouring continued up to be joined to the copper wires just above the to edge of the lower wallboard. It is intended that later versions of Kiosk No. 8 will have the earthing boss higher, so that it is behind the upper wallboard.
    

3. The lower wallboard should be fitted and whilst it is being positioned, the single length of Wire Earthing 9142/1W Grey and a draw wire, to pull in the speech pair of the Cable Polythene Twin No. 3 later on, should both be inserted in the hole in the lower wallboard provided for these conductors.
    

4. The Kit No. 176A should then be fitted in accordance with Works Specification S(W) 2144. The single length of Wire Earthing 9142/1W Grey should be connected to the earth terminal inside the Kit No. 176A (Terminal B16 see Diagram N 805). The cupped washer on the terminal should be inverted to provide a secure fixing for the earth wire. The Mechanism No. 24A and Cover No. 50C should be refitted. The dial centre label should be fitted at this stage if possible.
   
   The mechanism compartment should be locked. The cash compartment should be fitted with a Container Cash No. 7 and the Cash Compartment locked.
   
   Directories should be fitted where appropriate or, when directory holders are not provided, taken along when the kiosk is to be erected.
    

5. The upper wallboard may be fitted at this stage although it will need to be removed on site for soldering the 3 twisted wires from the kiosk earthing boss to the armouring of the Cable Polythene Twin No. 3 when the kiosk is erected.
   
   Alternatively it should be obtained in readiness to be taken out and fitted upon erection of the kiosk. Notices should be obtained in readiness for fitting into the upper wallboard.
    

6. Lighting equipment should also be installed prior to the kiosk being transported to site. This equipment should be installed in accordance with TI H11 E3000 in readiness for the connection of the mains electricity supply by the electricity authority. See also Drawing P/EL 878 which details the electrical arrangements.
    

7. Remove all protruding bolt and screw ends on the outside of the kiosk with a cold chisel.
   
   Redress all putty used in the joints between the various sections of the kiosk and touch up where necessary with Paint Red 539.
   
   Paint all unprotected screw ends etc and touch up paintwork where necessary using:-
   
   Paint, Black for Ironwork (Roof Ring and Sill)
   Paint, Enamel White (Inside of Roof Dome)
   Paint, Red 539
   
   (This work should be done sufficiently in advance of kiosk erection for the paint to be dry).
    

8. The tapped holes in the kiosk are pre-filled with an anti-seize grease. In case any of this grease has found its way onto the exterior of the kiosk back-panel, especially after fitting the internal equipment, this part of the kiosk should be wiped down with cotton waste to remove any trace of the grease. White spirit may be used to dissolve any grease.

11. TRANSPORT OF KIOSK TO SITE
Using a Trailer Kiosk No. 1 the kiosk should be transported to site. After removal of the framework from the concrete foundation the kiosk should be placed in its position on the concrete foundation. The trailer is described in TI J3 B0011. It has rotating framework, driven by a hand operated hydraulic pump, and is designed to clamp around a kiosk standing in the vertical position and rotate it onto the trailer to lie in a horizontal position. The trailer is then used to transport the kiosk to the site and place it vertically on the concrete base. It must be ensured that the kiosk is securely clamped to the trailer. The grooves in the clamping bars must be located over the vertical flanges of the kiosk before tightening. TI C1 A8115 shows how to use kiosk trailers for Kiosk No. 6. Until the TI is reprinted it can be used as a guide on how to use the trailer but differences must be taken into account when using it for a Kiosk No. 8. Trailers designed for Kiosk No. 6 only should have been modified in accordance with Works Specification MT 5/69 so that they will handle Kiosks No. 8 also.

12. BOLTING DOWN THE KIOSK AND FILLING THE SILL
The kiosk must be checked for vertical alignment, using a spirit level and corrected if necessary by means of the levelling screws in the base of the sill. When the kiosk has been positioned correctly, with the ducts for the telephone and electricity supply cables set back against the edge of the sill, it should be bolted down to the foundation with the four bolts and washers from the Anchors No. 2A passed through the sill of the kiosk into the sockets of the Anchors No. 2A which will now be embedded in the concrete. The washers should be fitted directly under the heads of the bolts. Care should be taken to avoid over-tightening these bolts and so straining or damaging the cast iron sill. The telephone lead-in-cable should be moved out of the way. The sill of the kiosk should then be filled with 0.75 ballast evened out to within 2" of the curved section of the sill to provide a base for a concrete slab. The sill frame is designed to give a slight fall toward the door for drainage purposes and the ballast should follow this line at 2" below the curved section. The ballast should be pushed into position all around the ducts and well tamped. The concrete slab referred to in Para 8 should then be laid flat on top of this ballast in the sill so that it fits snugly into the sill of the kiosk, opposite the ducts. This will leave a clear rectangular area around the ducts adjacent to the back panel which must then be filled with concrete to the sides of the sill. Concrete must also be grouted in to the small gap around the three remaining sides of the slab.

The kiosk is then ready for the connection of the telephone lead-in and earth.

A concrete fillet about 2" deep should be made around the outside of the kiosk sill and at the same time any gaps between the kiosk sill and the foundation should be filled although this will be minimal if the foundation is level.

13. TERMINATION OF LEAD-IN-CABLE IN KIOSK
As previously stated in armouring wires of Cable, Polythene No. 3 are used to provide the connection between the earth electrode and the kiosk. To terminate the earth in the kiosk, remove the outer Polythene Sheath to approximately 6 inches below the hole in the lower wallboard provided for the incoming speech pair and coinbox telephone earth to the Kit No. 176A. Separate the armouring wires from the inner Polythene sheath. Group together the armouring wires and twist them along their length. Cut this twisted length approximately 6" above the lower wallboard ready for connecting to the 3 twisted lengths of Wire earthing 9142/1W Grey, from the Socket Soldering Type 1, 8D, already bolted to the kiosk as described in paragraph 10.

Leaving sufficient slack for terminating the telephone cable in the coinbox, remove the inner Polythene sheath to within 3" of the outer sheath. This cable should be secured to the lower end of the kiosk back panel by Cleats Wiring No. 1.

Pull the speech pair into the Kit No. 176A and terminate onto the appropriate terminals. It should be checked that the single length of Wire Earthing 9142/1W Grey, has already been connected to the earth terminal of the Kit No. 176A.

The twisted armouring must be joined to the 3 copper wires from the Socket Soldering Type 1, 8D. To do this the 3 copper wires should be wrapped around the armouring four times and the connection soldered. This joint should be made just above the top edge of the lower wallboard. The excess armouring should be cut off. The upper wallboard and notices etc should then be replaced.

The mechanism and Cover No. 50C should be replaced as described in Works Specification S(W) 2144 and the installation tested as required by TI C3 G7004 and should include a ring back to cheek the kiosk telephone number.

14. SEALING DUCTS AGAINST GAS LEAKAGE
All Telephone, earth and EL cable entry points should be sealed in accordance with TI A2 Fo452.

The telephone cable duct should also be sealed at the joint box end.

15. FINAL CHECK
The kiosk should be given a final check all round and the rear panel and other parts of the kiosk given a wipe with cotton waste and white spirit before leaving the site.

16. PREVENTION OF ACCESS
If the internal apparatus cannot be fitted before the kiosk erection, and pre-painting is not possible, then every effort must be made to prevent the public coming into contact with wet painted surfaces or having access to the kiosk until the apparatus is fitted. Guards should be provided and Wet Paint Notices conspicuously displayed on the inside of windows when necessary.

17. TOOLS
The Kiosk No. 8 has been designed and constructed to metric standards. Bolts and screws have metric threads. Bolts are hexagon headed and the ISOM spanners listed below will be required. Most screws are of the recessed head type (POZIDRIV) but the screws for the glazing strips and those for fixing the door closer are ordinary slotted heads and need only be considered from the maintenance aspect.

All equipment fixing holes are tapped before the kiosk leaves the manufacturer. However the taps listed below should be held in case it may be necessary to clear the holes before use. These tools will be stocked by Purchasing and Supplies Department, Supplies Division, but until such time they are available should be obtained on local purchase.

Tools required, in addition to normal installation tools:-
