CAUTION!
Any work on the heat pump may only
be performed by an authorized and qualified after-
sales service.
Prior to opening the unit, all of its
electric circuits must be disconnected from the
power source.
CAUTION!
Caution - Heating Technicians !
Depending on the filling 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 reason for this is the water hardness and
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
conditio-ner such as ELYSATOR be used.
8.3 Cleaning of Heat Source Side
A strainer is fitted in the heat source inlet of the
heat pump in order to protect the evaporator
against contamination. Initially, the filter screen
of the strainer should be cleaned at relatively short
intervals. Once there is less contamination, the
intervals can be extended accordingly.
8.4 Water Quality Requirements
To prevent any so-called "ochredisation" (depo-
sition of iron and manganese) of the heat pump
system from occurring, the ground water must be
free of all substances that could result in mineral
deposits, and the limit values for IRON (< 0.2 mg/
l) and MANGANESE (< 0,1 mg/l) must be complied
with.
The use of surface water or saline water bodies
is not permitted. Consult your local waterworks
for some general information about any possible
ground water usage. Water analyses are prepared
by laboratories specialising in water technology.
No water analysis with respect to any corrosion
of the evaporator is required if the average annual
ground water temperature is not in excess of
13
° C. In this case, only the limit values for iron
and manganese must be met ("ochredisation"
risk).
MALFUNCTIONS/
TROUBLESHOOTING
This heat pump is a quality product and designed
for trouble-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. Simply consult the Malfunctions
and Troubleshooting table in the operating
manual of the controller.
Additional malfunctions can be interrogated at the
heat pump controller.
If the problem cannot be corrected by the user,
please contact the after-sales service in charge
(see Warranty Certificate).
CAUTION!
DECOMMISSIONING
10.1 Placing Out of Service in
Summer
Placing the heat pump out of service in summer can
be effected by switching the heat pump controller to
the "Summer" operating mode.
10.2 End-of-Life Decommissioning/
Disposal
Before removing the heat pump, disconnect the
machine from the power supply and close all
valves. Environment-relevant requirements re-
garding the recovery, recycling and disposal of
service fuels and components in accordance with
all relevant standards must be adhered to. In this
context, particular attention must be paid to the
proper disposal of refrigerants and refrigeration
oils
.
