USER MANUAL Push open GROHE

Safety and important information

This thermostatic valve will suit supplies of:

High pressure.

Conditions of use TMV2

	high pressure	low pressure
max. static pressure	10 bar	10 bar
flow pressure hot/cold	0,5 to 5 bar	0,1 to 1 bar
hot supplied temperature	55 to 65 °C	55 to 65 °C
cold supplied temperature	equal to or less 25 °C	equal to or less 25 °C

NOTE: Valves operating outside these conditions cannot be guaranteed by the Scheme to operate as Type 2 valves.

The designation of use is high pressure tub (HP-T) and high pressure shower (HP-S).

HP-S for 34 438 and 34 557

HP-S and HP-T for 34 439

If a water supply is fed by gravity then the supply pressure should be verified to ensure the conditions of use are appropriate for the valve.

Recommended outlet temperature

• 44°C for bath fill

but:

• 41^ for shower and washbasin
• 38^ for bidet

The mixed water temperatures must never exceed 46^

The maximum mixed water temperature can be 2^ above the recommended maximum set outlet temperatures.

NOTE: 46^ is the maximum mixed water temperature from the bath tap. The maximum temperature takes account of the allowable temperature tolerances inherent in thermostatic mixing valves and temperature losses in metal baths.

It is not a safe bathing temperature for adults or children.

The British Burns Association recommends 37 to 37.5^ as a comfortable bathing temperature for children. In premises covered by the Care Standards Act 2000, the maximum mixed water outlet temperature is 43^ .

The thermostatic mixing valve will be installed in such a position that maintenance of the TMV and its valves and the commissioning and testing of the TMV can be undertaken.

Requirements shall be verified against the original set temperature results once a year.

The installation of thermostatic mixing valves must comply with the requirements of the Water Supply (Water Fittings) Regulations 1999.

The fitting of isolation valves is required as close as is practicable to the water supply inlets of the thermostatic mixing valve.

Notes

If there is a residual flow during the commissioning or the annual verification (cold water supply isolation test), then this is acceptable providing the temperature of the water seeping from the valve is no more than 2^ above the designated maximum mixed water outlet temperature setting of the valve.

Application

Thermostat mixers are designed for hot water supply via pressurised storage heaters and, utilised in this way, provide the best temperature accuracy. With sufficient power output (from 18kW or 250 kcal/min), electric or gas instantaneous heaters are also suitable.

Thermostats cannot be used in conjunction with non-pressurised storage heaters (displacement water heaters).

All thermostats are adjusted in the factory at a flow pressure of 3 bar on both sides.

Should temperature deviations occur on account of special installation conditions, the thermostat must be adapted to local conditions (see Adjusting).

Specifications

Minimum flow pressure without downstream resistances 0.5 bar

Minimum flow pressure with downstream resistances 1 bar

Max. operating pressure 10 bar

Recommended flow pressure 1 - 5 bar

Test pressure 16 bar

Flow rate at 3 bar flow pressure

Bath approx. 20 l/min

Shower approx. 14 l/min

Max. water temperature at hot water supply 70^

Recommended max. flow temperature (energy saving) 60^

Safety stop 38^

Hot water temperature at supply connection min. 2^ higher than mixed water temperature

Cold water connection right

Hot water connection left

Minimum flow rate

= 5l / min

If static pressure exceeds 5 bar, a pressure reducing valve must be fitted.

Installation

Flush piping system prior and after installation of fitting thoroughly (Consider EN 806)!

Install unions and screw-mount the mixer, see fold-out page I, Fig. [1].

Refer to the dimensional drawing on fold-out page 1.

The projection can be increased by 20mm with an extension, see Replacement Parts, fold-out page II, Prod. no. 07 130.

Open cold and hot-water supply and check connections for water-tightness.

Reversed connection (hot on right - cold on left).

Replace thermostatic compact cartridge, see Replacement parts, fold-out page II, Prod. no.: 47 175 (1/2").

When using this thermostatic compact cartridge, the Cool Touch function is no longer available.

Adjusting

Temperature adjustment, see fold-out page I Fig. [2].

Temperature limitation

The safety stop limits the temperature range to 38^

The 38^ limit can be overridden by pressing the button, see Fig. [3]. Temperatur end position is at 46^ .

If 43^ temperatur end position is desired please take the temperatur limiter (in the scope of delivery) shown in Fig. [3].

Shower mixer:

Adjusting the economy stop, see fold-out page III Fig. [4].

If a higher flow rate is desired, the stop can be overridden by pressing the button, fold-out page III Fig. [5].

Bath mixer:

Handle operation, see fold-out page III Fig. [6].

Eco function, by pressing the button the flow rate for the shower can be increased.

Prevention of frost damage

When the domestic water system is drained, thermostat mixers must be drained separately, since non-return valves are installed in the hot and cold water connections. For this purpose, the mixer must be removed from the wall.

Maintenance

Inspect and clean all parts, replace if necessary and lubricate with special valve grease.

Shut off the hot and cold water supply.

Non-return valve, see fold-out page III, Fig. [7].

Remove connection nipple using a 12mm allen key.

Install in reverse order.

Thermostatic compact cartridge, see fold-out page IV, Fig. [8].

Install in reverse order.

Readjustment is necessary after every maintenance operation on the thermostatic compact cartridge (see Adjusting).

Aquadimmer (bath mixer), see fold-out page IV, Fig. [9].

Ceramic headpart (shower mixer), see fold-out page III and IV, Fig. [4] and [10].

Install in reverse order.

Unscrew and clean mousseur (13 952) see fold-out page II.

Shower, see fold-out page IV, Fig. [11].

The function of the SpeedClean nozzles is guaranteed for a period of five years.

Thanks to the SpeedClean nozzles, which must be regularly cleaned, timescale deposits on the rose can be removed by simply rubbing with the fingers.

Replacement parts, see fold-out page II ( ^* = special accessories).
