Grohe 34161000 grohtherm 1000 [6/60] Application

Application

Thermostat mixers are designed for hot water supplies from

pressurised storage heaters and offer the highest temperature

accuracy when used in this way. Given sufficient output

(min. 18 kW or 250 kcal per min), electric or gas-fired

instantaneous heaters are also suitable.

Thermostat mixers cannot be used in conjunction with low-

pressure storage heaters (displacement heaters).

All thermostat mixers are adjusted at the factory at a flow

pressure of 3 bar on both sides.

A shutoff device (A) must be installed after the mixed water

outlet of concealed thermostatic mixer (34 160), see fig. [1].

For an order number index to the various installation

components for the concealed mixer, see fig. [2].

a = Size of union

b = Part

c = Part No.

When this model is used as a central thermostat, standard

mixers can be installed at the draw-off points, in this case, the

thermostat mixer supplies hot water to which cold water can be

added.

The built-in thermostat with stop-valve (34 161 / 34 162) only

shuts off the upper outlet. An additional stop valve must be

fitted if the lower outlet is used, see fig. [2].

Technical Data

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

34 160 approx. 40 l/min

34 161, 34 162 approx. 26 l/min

Max. water temperature at hot water inlet 80 °C

Recommended max. flow temperature 60 °C

(for energy saving)

Safety stop 38 °C

Hot water temperature at supply connection min. 2 °C higher

than mixed water temperature.

Hot water connection - W - (-H-) left

Cold water connection - K - (-C-) right

Minimum flow rate 5 l/min

At a flow pressure over 5 bar it is recommended that a

pressure reducing valve be fitted in the supply line.

Prevention of frost damage

When the domestic water system is drained, the thermostat

mixers must be drained separately, since non-return valves

are installed in the hot and cold water connections. The

complete thermostat assembly and non-return valves must be

unscrewed and removed.

New installations

- Prepare wall ready for mixer.

Drill holes for thermostat mixer and chase-out grooves for

pipelines.

Observe the installation depth in accordance with the

instructions given on the mounting template, see also

fig. [3].

x = Face of tiles

y = Front face of mounting template

z = Resting point for spirit level

- Align the mixer horizontally, vertically and parallel to the wall,

see fig. [4] (place a spirit level on the cams or face of the

mounting template).

- Install concealed thermostat mixer module in wall and

connect pipelines, see fold-out page III fig. [5].

The housing is provided with pre-drilled holes (B) to facilitate

mounting the fitting to the wall, see fold-out page I fig. [4].

- Do not solder the connections between the pipelines

and housing, otherwise the built-in non-return valves may

be damaged.

- Seal the open outlet with screw plug.

Note!

- The hot water supply must be connected on the left

(marked W (H) on housing) and the cold water supply on

the right (marked K (C) on housing), as viewed from the

operating position.

Test the pipelines and concealed thermostat module

connections for leaks.

Flush pipelines thoroughly.

1. Remove screws (C) and mounting template (D), see

fig. [6].

2. Close the hot and cold water supplies.

3. Remove screw plug (E).

4. Remove non-return valve (F) and filter (G).

5. Install flushing plugs (H) in non-return valve seat recesses,

see fig. [7].

6. Open the hot and cold water supplies and flush pipes

thoroughly.

7. Close the hot and cold water supplies and remove flushing

plugs (H).

8. Install filter (G) and non-return valve (F), see fig. [6].

9. Install screw plug (E).

10. Reinstall mounting template (D).

Plaster and tile the wall, excluding the area occupied by the

mounting template. Seal any apertures in the wall so that they

are watertight to spray water.

• Tiles laid in mortar should be pointed so that the joint is

tapered towards the outside.

• Seal prefabricated walls with a permanently plastic

compound.

Do not remove the fitting template before final installation.
