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 requirements
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. Application

Standard thermostatic mixing valves TM3400/TM3410 are
used in domestic hot water central heating systems with or
without recirculation. The aim is to maintain a constant
temperature of the mixed water for users, by varying the
temperature of the hot water stored. Thermostatic mixing
valves also have applications in underfloor heating applica-
tions and in alternative energy systems, such as solar and
woodchip systems.

3. Functional description

The highly sensitive thermal element located in the outlet of
the mixing valve controls a plug which regulates the flow
proportions of cold and hot water in relation to the mixed hot
water setting selected.

8. Assembly

8.1 Installations Guidelines
• The thermostatic mixing valves can be installed in any
position
• With any connections to be welded, during welding
remove the mixer so as not to damage the thermostat and
seals
• It is recommended that interception valves are installed on
the connection ways to the mixer
• The polystyrene packaging may be used as insulation for
the valve
