11. MAINTENANCE
Due to its design the heat pump is very easy to maintain. Basic maintenance is performed by the servicing
organization once a year. During this regular maintenance, all important elements of the heat pump are
checked. Special attention is paid to the correct volume of refrigerant in the circuit and a proper operation of
the refrigerant circuit.
It is important to observe the outdoor unit evaporator status. The best way to clean the outdoor unit is by using
the garden washer with hot water. This way, dirt and eventual frost is cleaned from the evaporator.
Do not use high pressure cleaners and any other mechanical tools (brush etc.). The evaporator
is very fine and could easily be damaged. Prior to the outdoor unit evaporator cleaning,
switch off the main breaker of the indoor unit!
Circulation pump
The indoor unit requires minimal maintenance. Use a wet cloth to clean the dust from the upper casing. Be extra
careful when cleaning the heat pump during its operation. It is recommended to cleaning the indoor unit after
the heating season and when it is disconnected.
Before the heating season, check the circulation pump operation for possible jamming. This is indicated by
a circulating pump lamp. The pump has a automated program which is trying for some time to release the
blocked shaft. Once a year, have the functionality of the expansion tank checked. Also check the heating water
filter.
All this maintenance should better be performed by an authorized organization during regular servicing.
Prior to removing the heat pump cover, disconnect the heat pump from the network.
There is a great risk of injury by electric current.
