If the throttle is dirty and does not operate freely, it should be cleaned according to one of the following
methods:
•
using a hoover with a soft suction nozzle,
•
by blowing with compressed air,
•
washing with water and non-corrosive cleaning agents for aluminium.
After re-installation, the damper should be carefully sealed, above all on the outside air intake side, to
prevent the water heater from freezing.
MINIMUM SCOPE OF PERIODIC INSPECTIONS
1 Verification of the operating time of the heat pump and, based on this, an assessment of the
operating status of the unit
2 Interview with the user - writing down comments of use
3 Alarm history overview - indication of stored alarms
4 Site visit (checking the general condition of the unit, e.g. excessive icing, assessing sound
levels, patency of exchanger fins),
5 Check for leaks in the refrigeration circuit. If there are indications of refrigerant loss (e.g. oil
stains on the hoses or compressor plate); check with a leak detector
6 Checking the condition (replacement) of the filter drier
7 Checking (cleaning, repairing) the patency of the heat exchanger fins - supply air
8 Checking (cleaning, repairing) the patency of the heat exchanger fins - exhaust
9 Measuring system pressure at standstill
10 Measurement of system pressure during operation
11 Control of the heat pump's operating parameters (maintaining adequate temperature
differences in the lower and upper heat sources).
12 Checking the operation of the appliance components (i.e. switching valves, electric heater,
safety devices),
13 Checking that the electrical connections are properly seated and that the bolted connections
of the electrical cables - power and Controls - are securely fastened
14 Electrical connection - checking for correct voltages and currents
