1.2. Routine maintenance

Proper maintenance is very important to optimise the operation and to ensure long service life of the heat

pump. The following points should serve as general instructions; always consult your installation company

for specific maintenance requirements.

The evaporator should be cleaned at least twice per year and each time when it is visibly fouled. Fouled

evaporator lowers the efficiency of the operation. The external surfaces of the heat pump may be washed

with a sponge and a warm soap water. Do not use bleach, abrasives or solvents, which could damage the

surface of the device. The detergent should not contain acids, soda or chlorides. Make sure that the parts

with electrical installation are protected against ingress of water.

! !

Check regularly the outdoor unit at below zero temperatures if there isn’t an excessive built up of frost or ice

under the pump. Snowing or strong wind can cause obstruction or snowbound closure of the evaporator

inlets. Icing and snow must be removed.

Filters:

The heating circuit of the pump is fitted with filters, which can be clogged. Check these at last twice a year.

Close the nearest valves before and after the filter and remove the sieve. After installation deaerate the

heating system and fill up the water in the heating circuit.

ATTENTION: The heat pump air-water contains a fan, which can be revolving.

Before maintenance of the evaporator part of the heat pump always disconnect the power supply

and wait until all moving parts of the fan come to standstill!

Water draining at shut-down:

If the outdoor heat pump is out of operation for a longer period or if it is disconnected from the power supply,

drain the water out of the unit to prevent its freezing with the disconnected power supply. The indoor unit

placed inside premises free of the danger of frost does not have to be drained .

Warning: The water being discharged from the heat pump could be hot, beware of the danger of scalding.

ATTENTION:

If the heat pump does not start or if it does not heat, consult the situation with your installation

company. The heat pump cover should be removed only by a qualified worker.

The following should be checked by a competent service technician:

Electrical installation:

Check the connection and the condition of the electrical

Heating system:

The functioning of the heating system must be checked prior to the heating season.
