ENERGY SAVINGS
INSPECTION AND MAINTENANCE
To achieve as low energy consumption as possible for a longer period of
time, we recommend that you have an annual service and any
maintenance carried out by a competent person.
UNDERFLOOR HEATING
Do not set a flow temperature that is higher than the highest value
recommended by the floor manufacturer.
AIRING
Do not leave the windows ajar when you air. This makes heat leave the
room all the time, but the air quality in the room does not improve.
Instead, open the windows fully for a short time.
ADDITIONAL ELECTRIC HEAT
Different settings (e.g. extra hot water) lead to the activation of an
additional electric heat source and thereby to higher energy
consumption.
Always select a temperature setting for hot water and heating that is as
low as possible.

MAINTENANCE
The heat pump requires minimal upkeep. Some inspection is
recommended nevertheless for the heat pump to perform as well as
possible. Check the following points a couple of times during the first
year. Subsequently they should be checked occasionally during the
year:
• Safety valves
• Expansion vessel (plastic vessel collector circuit)
• Particle filter
16.1 CHECKING THE SAFETY VALVES
The safety valve should be checked by a qualified
engineer - usually as part of an annual service visit.
Never close the safety valve or obstruct it's discharge
pipe.
▶ Check that the waste water hose from the safety valve is not blocked.
16.2 EXPANSION VESSEL
A plastic expansion vessel is connected to the heat pump collector
circuit ("the cold side"). The level in the vessel must not be less than
minimum level 1/3. If the fluid level is too low, contact your installer.

16.3 PARTICLE FILTER
The particle filter (dirt filter) ensures that no particles or dirt get into the
heat exchangers. In time, the filter can become clogged and must be
cleaned. There are particle filters on both the "hot and cold sides". The
particle filter should be cleaned as follows:
▶ Switch off the heat pump with the ON/OFF button.
▶ Shut the valve and screw off the sealing lid.
▶ Release the locking ring which holds the sieve in the valve. Use the
accompanying locking ring bar. (Image 32)
▶ Lift the sieve out from the valve and rinse it clean with water.
▶ Replace the sieve, the locking ring and the sealing lid.
▶ Open the valve and start the heat pump with the ON/OFF button.
