Maintenance
Hot water heater safety valve
The water heater’s safety valve sometimes releases a little
water after hot water usage. This is because the cold water,
which enters the heater to replace the hot water, expands when
heated causing the pressure to rise and the safety valve to open.
Also check the water heater safety valve regularly. The
appearance and location of the safety valve differs between
different installations. Contact your installer for information.
Pressure gauge in indoor unit
The working range of the heating system is normally 0.5 – 1.5
bar when the system is closed. Check this on the pressure
gauge (BP5).
Emptying the hot water heater
The water heater is of the coil type and is drained using the
siphon principle. This can be done either via the drain valve on
the incoming cold water pipe or by inserting a hose into the
cold water connection.
Emptying the vessel
Contact your installer if the vessel in indoor unit needs
emptying.
Maintenance of outdoor unit
Outdoor unit is equipped with control and monitoring
equipment, however some exterior maintenance is still
necessary.
Make regular checks throughout the year that the inlet grille is
not clogged by leaves, snow or anything else. During the cold
months of the year, check to make sure that there isn’t a build up
of ice or frost under outdoor unit. Strong wind combined with
heavy snowfall can block the intake and exhaust air grilles.
Make sure that there is no snow on the grilles.
Also check that the condensation water drain under outdoor unit
is not blocked.
If necessary the outer casing can be cleaned using a damp
cloth. Care must be exercised so that the heat pump is not
scratched when cleaning. Avoid spraying water into the grilles
or the sides so that water penetrates into outdoor unit. Prevent
outdoor unit coming into contact with alkaline cleaning agents.

Saving tips
Your Hydrolution produces heat and hot water according to
your needs. It also attempts to carry out all requirements with
all available “aids” from the control settings made.
The indoor temperature is naturally affected by the energy
consumption. Therefore, take care not to set a temperature
higher than necessary.
Other known factors that affect the energy consumption are,
for example, hot water consumption and the insulation level of
the house, as well as the level of comfort you require.
Also remember:
■ Open the thermostat valves completely (except in the
rooms that are to be kept cooler for various reasons, e.g.
bedrooms).
Thermostat valves in the radiators and floor loops can
negatively affect the energy consumption. They slow the ow
in the heating system, which the heat pump wants to
compensate with increased temperatures. It then works harder
and consumes more electrical energy.
