ü
Keep air pathways clear
–
Always keep the suction and discharge area of
the heat pump free (e.g. observe changed vege-
tation, drifting snow, ...).
–
Remove snow deposits on the top and back of the
heat pump to prevent ice formation.
Clean evaporator
If necessary, wash off dirt or dust deposited on the
evaporator surface.
To do this, spray detergent onto the evaporator fins,
then rinse with water.
!
CAUTION
- The evaporator's thin aluminium
fins are fragile and may be damaged by care-
less handling.
–
Clean only with low water pressure.
–
Do not work with high-pressure washer.
–
Wear gloves to protect against cuts.
Check system pressure
The water pressure in the heating system can be
read on the pressure gauge. As a rule of thumb (for
buildings of up to three storeys), the pressure should
be 1 to 2 bar for a cold system and 1.5 to 2.5 bar for a
hot system.
It is important that the pressure remains constant at
all times. A constant fall in pressure requires the addi-
tion of extra water and indicates a fault in the system
(e.g. a leak).
i
TIP: Make a note of the set system pressure
during initial commissioning.
Remove dirt and leaves
Remove dirt and leaves deposited on the heat pump
with a hand brush.
Remove cladding
Remove accumulated dust and debris on the outside
of the cladding with a damp cloth.
i
Do not use acidic, chlorine-containing or basic
detergents or abrasive cleaners.
Clean dirt and sludge trap
The trap prevents impurities from entering the heat
pump from the heating system. Uncleaned traps can
cause faults.
Cleaning the trap:
The trap can be cleaned during operation, i.e. no drai-
nage of the lines is required.
►
Unscrew magnetic rod
1
from the immersion
sleeve.
►
Briefly open the desludging tap
2
.
►
Close the desludging valve again, screw in the
magnetic rod.
Detailed information is provided in the trap manu-
facturer’s documentation, DR-0069.
Moisture
Directly below the heat pump, condensation from
water may form some moisture that is not caught by
the condensate tray. This is normal and does not
require special measures.
If a larger amount of liquid should escape outside the
heat pump, switch off the heat pump and contact the
system installer.
15.2 Maintenance by qualified personnel
Regular maintenance not only includes the annual
inspection of the device, but also the optimization of
the system for a more efficient functional sequence of
the individual components. This not only extends the
life of the device, it also saves energy costs.
Contact your heating engineer or the SOLARFOCUS
Service Hotline
Arrange for a heat pump maintenance contract
By purchasing a maintenance agreement,
SOLARFOCUS will manage the annual appointment
and contact you directly when a maintenance appoint-
ment is due.
