Caution - Heating Contractors
Depending on the water quality and quantity, in
particular in the case of mixed installations and
plastic pipes, mineral deposits (rust sludge, lime)
may form impairing the proper functioning of the
heating installation. A cause of this is the water
hardness as well as oxygen dissolved in the filling
water as well as additional oxygen from the air which
may penetrate via valves, fittings and plastic pipes
(oxygen diffusion). As a preventive measure it is
recommended that a physical water conditioner such
as ELYSATOR be used.
9.3 Cleaning of Air Side
Finned heat exchangers, fan and condensate drain
should be cleaned of debris (leaves, branches, etc.)
prior to the start of the heating season. Contamination
of this nature can be removed manually using
compressed air or by washing off with clear water.
The appliance cover and the air intake grille may have
to be removed for this purpose.
Prior to opening the unit it must be
ensured that all electrical circuits are disconnected
from the power supply.
When cleaning do not use any sharp or hard objects
so as to prevent any damage to the evaporator and
the condensate pan.
Extreme weather conditions (e.g. heavy snow) may
in some cases result in ice build-up on the inlet and
outlet grilles. To assure a minimum air flow rate, clear
the inlet and discharge areas of snow and ice, if
needed.
MALFUNCTIONS /
TROUBLESHOOTING
This heat pump is a quality product and is designed
for troublefree and maintenance-free operation. In
the event that a malfunction occurs nevertheless,
you will be able to correct the problem easily yourself
in the majority of cases.
Heat pump does not run!
Please check that:
- there is no problem with the power supply (blown
fuse, power failure).
- the power switch on the remote control is switched
on and the correct operating mode is selected, as
well as that the correct setpoint temperature is set.
CAUTION!
The preset temperature level cannot be reached!
Please check whether
- the permissible operating conditions of the heat
pump are complied with (air temperatures too high
or too low).
- the air inlet or outlet areas are neither covered,
obstructed nor severely contaminated.
- valves or stop-cocks in the water lines (heating
lines) are closed.
- t h e w a t e r t e m p e r a t u r e i n t h e b u f f e r t a n k i s
sufficiently high.
If you cannot eliminate the malfunction yourself,
please contact your customer service in charge (see
Warranty Certificate).
Work on the heat pump may be done
only by an authorized and qualified customer service.
