1. Safety Guidelines
1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the appli-
cations detailed in these installation instructions. Any
other use will not be considered to comply with require-
ments and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out by
authorized persons.
5. Immediately rectify any malfunctions which may influence
safety.
2. Description of function
Thermostatic mixing valves of this type are used for central
regulation of the water temperature in solar-powered, bivalent
water heaters.
The highly sensitive thermal element located in the outlet of
the valve controls a plug which regulates the flow proportions
of cold and hot water in relation to the mixed hot water setting
selected. Soft seatings are fitted to both hot and cold water
inlets.
They provide:
• A positive hot inlet shutoff if the cold water supply is inter-
rupted, provided that the hot water inlet temperature is at
least 10 K higher than that of the mixed water setting.
• The cold water supply is cut off if the hot water supply is
interrupted.

7. Assembly
7.1. Installations Guidelines
• Fit a return flow-retarder unit where the hot water supply
system includes a circulation circuit
• Observe the flow direction arrow when fitting a KB191
return flow-retarder unit
• To prevent the growth of legionella, DVGW-W551 specify
that the water volume in the pipework between the mixer
valve and the furthest take-off point should not exceed 3
litres. This corresponds to a maximum length of 10 metres
for
/
" (20 mm) pipework and 17 metres for
3
4
7.2. Assembly instructions
The flow direction arrows must be observed when connecting
the hot and cold water inlets.
• Install so that the valve is not strained or twisted
7.3. Set Mix Water Temperature
The mixing valve can be set within the range 30°C to 60°C as
follows:
• Remove the protective cap.
• Rotate setting wheel until the desired temperature number
coincides with the marking
7.4. Locking the setting (not in TM50SOLAR)
Once the correct setting has been achieved it can be locked
in position.
1. Place the protection cap (1) over the control knob
• Ensure the notch (3) in the protection cap and lug (4) on
the valve are engaged
2. Secure the cap in place with the screw provided
3. The valve is now ready for use
• The actual set point temperature can be viewed through
the clear window (2) on the locking cap
8. Start-up
1. Check that the designation of the valve matches the
intended application, that the supply pressures are within
the range of operating pressures and that the supply
temperatures are within the range permitted for the valve
from guidance information on the prevention of legionella.
