Introduction

902-T

The 902-T shower valve is thermostatically controlled.

The NewTeam 902-T Mixer Valve is suitable for the following:

•High Pressure systems to a maximum of 8.0 Bar (50 Metre Head).

•Low Pressure systems with a minimum pressure of 0.1 Bar

(1 Metre Head).

•Pumped Pressure.

•Mains Pressure.

Ideally the supplies should be independent of any other draw offs (e.g.

bath/basin taps).

The Thermostatic Valve includes a Temperature Limit Stop which is

pre-set at approximately 38˚C thus preventing accidental selection of

a shower temperature which is too hot.

If the minimum operating pressure cannot be achieved or you wish to

improve the performance of your shower, NewTeam Booster Pumps

are available.

IMPORTANT:

When connecting pipework do not solder within 300mm (12”) of the

valve or expose parts to excessive heat.

NOTE - That at temperatures above 65ºC air can be expelled from the

water, which can cause poor performance, particularly with pumped

systems, where damage to a pump could occur.

Plumbing - Fig 1

Please ensure compliance with all Water Supply (Water Fitting) Regulations,

paying particular attention to Clause 15 in Water Regulations, when connecting

directly to incoming cold water mains.

The Mixer Valve must be sited to provide easy access for use and maintenance.

Install non-restrictive full flow isolating valves on the hot and cold supplies to the

Mixer Valve.

Ensure the Mixer Valve is not positioned in an area subject to freezing.

Make the connection into the hot water supply pipe from the cylinder ensuring

that it is the first draw off on the vertical pipe below the expansion pipe tee. If this

is not possible a direct connection must be made from the hot water cylinder with

an Essex flange.

The cold water supply should be taken directly from the cold water storage tank

positioned 60mm below the cold connection which feeds the hot water cylinder.

•The hot and cold feeds must be at nominally the same pressure. The valve must

not be fed from a low pressure (gravity system) hot supply and a mains pressure

cold supply.

•All pipework should be as short and direct as possible, using swept bends rather

than elbows where practical, to avoid trapping air. Do not tee off the upper surface

of a hot water pipe, especially near to a hot water cylinder, as this will often

contain air bubbles which will adversely affect the operation of the valves. Where

the shower is fed from a gravity system the use of 22mm diameter pipework is

strongly recommended.

•The combination boiler or gas multipoint boiler must be capable of raising the

temperature of 8 litres/min of incoming cold water by 45ºC. This requires a boiler

rating of 25kW (85300 Btu/h).

•The valves must be installed with the outlet pointing downwards, the HOT water

coming in on the left and the COLD on the right as you view the shower on the

wall. The valve will not operate if the connections are reversed.

IMPORTANT:

Modern solder fluxes are extremely corrosive and can damage the valves. It is

essential that all pipework is thoroughly flushed through before connecting the

valve. This is so that flux, debris and swarf, which could permanently damage the

valve, are removed from the pipes.

•Plan the whole installation before you start. Cut the necessary pipework to length,

assemble and offer up to the installation before making and soldered joints.

•Carry out any cutting with a pipe cutter in preference to a hacksaw, to minimise

swarf. Always remove sharp edges.

General:

IMPORTANT

THE 902-T MIXER SHOWER IS HELD IN POSITION BY THE PIPEWORK. IT IS

ESSENTIAL THAT THE PIPEWORK IS RIGIDLY SUPPORTED CLOSE TO THE VALVE.

A CONCEALED WALL MOUNT FIXING IS INCLUDED WITHIN THE SHOWER BOX.

PLEASE REFER TO PAGE 6 OF THIS MANUAL.

The NT902 should only be fitted where water supply pipes are behind a panel or

studwork wall.

This method of fixing requires good access behind the wall or panel.

•Offer up the valve to the wall and mark the required positions of the hot and cold

inlet connections. When positioning the valve make sure to take into account the

intended position of the accessories riser rail.

Ensure there are no services such as gas, water pipes, electrical or telephone

cables beneath the surface of the wall before drilling.

•On plasterboard (studwork) or panel walls, make two holes on 150mm centres to

accept the 1/2”BSP end fitting (see Fig. 3).

•On an internal rendered brick or block wall, drill two 23mm diameter holes on

150mm centres with counterbores to accept the 1/2”BSP end fitting. If 15mm

pipework is used, drill 16mm holes (see Fig. 3).

Cut two pieces of pipe, equal in length to the thickness of the wall plus an allowance

for connection at the rear of the wall, terminate the pipework using a 15mm to 1/2”

BSP, or 22mm to 1/2”BSP female straight tap connector to suit the pipe diameter

used. (The tap connector should include a rotational hexagon nut and washer).

Tighten the 1/2”to 3/4”BSP ‘dog leg’connector to the pipework, loosely fit the two

cover plates half way along the 3/4”BSP thread.

Temporarily block the open ends of the pipework and pass through th

wall until the cover plates are hard against the wall, fit the pipework at the rear of the

wall and secure rigidly, ensuring the two outlets are level and the centres match

those of the valve inlets.

•Flush out the pipework and fit the valve with the outlet

connection downwards, without cover plates and check the

system for leaks.

•Refit cover plate.

•Screw the valve to the pipework ensuring the washer and

filter are inserted, then fully tighten.

•Adjust the cover plates to take up any slack and stiffen the

assembly.

Note: If the non-return valves have to be removed at any time,

please note the bushes are Left hand thread

Fitting The Shower

NB: The following instructions are for fitting the shower with the

installation bracket (Fig 4).

The NT902 should only be fitted where water supply pipes are behind a panel or

studwork wall.

•Identify all components and check for completeness, particularly before

arranging fitting.

•Fix the mounting plate to the internal wall or studding using suitable fixings

(not supplied). Use a spacing batten or similar as necessary. Connect the hot and

cold water supplies using 15mm copper pipe with the nuts and olives (supplied).

Supplies can come from above or below making sure Hot is on the left and

Cold is on the right when viewed from the front.

•Finish the wall and push-fit the shrouds as shown. Note! A small bead of silicon

sealant between the wall finish and the spigot diameter under the shroud should

prevent any moisture entering the wall.

•Fit the mixer body to the 3/4”BSP mounting spigots using the large sealing

washers supplied with your fitting.

Fitting the Riser Rail

7NEWTEAM 902-T SHOWER VALVE

Before proceeding with fitting the rail, identify each of the itemssupplied using

the illustration.

The slider must not be removed from the rail during fitting. The top of the slider has

a smooth profile, whereas the underside has a recess revealing the grooves on the

handset holder.

Fit the rail through the friction sleeve on the soap/gel dish with the sleeve towards

the lower end of the rail.

Fit the rail ends onto the ends of the rail.

Position the rail on the wall, bearing in mind the heights of people

likely to use the shower, and mark the wall to indicate the upper and lower fixing

screw positions. Drill the wall at one of the marked fixing positions using a 6 mm drill.

Loosely fix the appropriate rail end and check that the other fixing screw mark is in

the correct position.

Secure the rail to the wall. Ensure that the rail is vertical before finally tightening both

fixing screws.

Fit the rail end caps.

When fitting the hose, it should pass through the centre hole of the soap dish.

NOTE - The hose nut, and not the handset handle, fits into the slider, and the slider

moves more freely on the rail, if gripped next to the rail rather than at the handset.

•These mixer valves have been calibrated at the factory using

balanced pressure hot and cold supplies and a hot water supply

temperature of 65ºC.

•When the installation conditions of the mixer valve are different to

the factory settings, the temperature of the mixed water obtained

from the mixer valve may not correspond exactly with the

temperatures shown on the valve.

If required, the valve can be adjusted to ensure that the indicated temperature

is the same as the temperature obtained from the mixer. To do this, carry

out the following steps:-

1. Rotate the temperature control knob so that the water

issuing from the mixer is at 38ºC.

2. Without moving the temperature control knob, remove the

screw cover from the end of the knob and unscrew the

fixing screw.

3. Remove the control knob, complete with the black ring

containing the temperature figures.

4. Refit the end of the control knob so that the figure 38

corresponds to the indicator on the mixer body.

5. Replace the fixing screw and refit the screw cover.

Note. To set a different temperature at the limit stop position,

follow the above steps but adjust the temperature of the

water to correspond to the limiting temperature required

before the temperature control knob.
