6.1 Descaling
At high temperatures water separates out lime. This is deposited
on the inside of the tank. With increasing limescale build-up, the
amount of hot water inside the tank is reduced.
» Have a licensed installer descale the booster heater from
time to time. This extends the service life of the booster
heater.
» Scale cannot build up on the heat pump element.
A licensed installer who knows the local water quality will tell you
when the next maintenance appointment is due.
» Have your licensed installer check the sacrificial anode
regularly.
7. What to do if ...
7.1 ... the water heater does not deliver hot
water
» Check the water heater power supply.
» Check your fuse box for a tripped circuit breaker.
» Make sure there is a 15 A double pole circuit breaker
If the circuit breaker has tripped, reset it or replace it. Notify your
local licensed installer if the circuit breaker trips again.
» Ensure that the air intake and air discharge are unobstructed.
Excessively high ambient temperature, excessively high
temperature of the air drawn in (> 42 °C (108 °F)) or a fault in the
refrigerant circuit can result in the compressor being overloaded.
The thermal protective 'auto reset' motor switch or the high limit
'manual reset' cut-out can both shut off the compressor off.
The high limit pressure limiter must only be reset by
your licensed installer after they have removed the
cause of the relevant fault.
After a short cooling down period, the thermal protective motor
auto reset switch will restart the compressor automatically.
Notify your local licensed installer if the water heater does not
restart automatically.
7.2 ... the safety valve of the cold water supply
line is dripping
This unit can operate up to 0.48 MPa (70 psi) of inlet pressure.
Expansion water drips from the safety valve during heat-up. This
is completely normal. Notify your local licensed installer if water
still drips after heat-up has been completed.
7.3 ... the condensate drain drips
This is quite normal and always happens when the surface
temperature of the evaporator is lower than the dew point
temperature of the ambient air.
7.4 ... the power consumption is too high
Please consult a qualified licensed installer.
7.5 ... the room temperature drops excessively
The water heater operation reduces the ambient air by
1 to 3 °C (2 to 6 °F). Notify your local licensed installer if the
ambient temperature drops abnormally.
7.6 ... other faults occur
Notify your local licensed installer. Refer to the water heater
number on the type plate next to the barcode.

Only qualified licensed installers should carry out installation,
initial start-up, maintenance and repair of the water heater.
8.1 General safety instructions
Use only original accessories and spare parts intended for this
water heater.
DANGER Electric shock
Disconnect the water heater from the power supply
prior to its installation.
WARNING Injury
If the pipes inside the water heater are damaged,
leaking refrigerant gas can result in severe physical
freezer burns.
Do not inhale refrigerant. Immediately vent the room
thoroughly.
» Wear safety goggles and gloves during water heater
installation.
