it with the protection cover on. This situation would cause insufficient amount of air (energy) for heat
pumps operations which would lead to almost none performance both by heating and cooling. This
situation would almost immediately lead to heat pump overheating which could cause a malfunction,
damage or a complete failure of the heat pump. Warranty does not cover any heat pump damage or
other damage caused by heat pump operations with the protection cover on.

HINTS AND TIPS
7.1
Water condensation
It is normal to have water dropping or leaking from the evaporator during heat pump operations,
particularly during heating. During heating, the evaporator is normally cold. It can easily reach dew
point conditions. Dew point means that at given air temperature and relative humidity any surface
that is of below dew point temperature condensates the water from surrounding air.
Condensation can result even in liters of water being leaked out of the heat pump. If you suspect a
leak on water circuit, as a first step it is advised to check if it is condensation. The condesated water
flows over the evaporator lamellas into the casing base. Then flows out through a plastic fitting
designed for connection to the ¾“ PVC tube by which the condensate can be taken to an appropriate
drain.
1.
Turn off the device and leave only the swimming pool pump (circulation pump) in operation.
If the water stops to flow out, then it is condensing water.
2.
Test, whether there is any chlorine or salt found in the outflowing water (if chlorine or salt are
used). If there is no chlorine or salt, then it is a condensate.
7.2
Winterizing
Split heat pump has been designed to have the water unit (water heat exchanger) installed in non-
freezing location. Should your application have risk of freezing up, please read through this section of
this Installation and user manual carefully.
Your heat pump continuously contains water in its water heat exchanger /water unit or hydrokit/. This
water will freeze up and damage irreversibly the heat exchanger if exposed to sub-zero air
temperatures, normally during winter time. It is then necessary to prepare the heat pump for sub-zero
air temperatures (e.g. winter time). Generally, the water from inside the water heat exchanger must
be removed. Winterizing is done on heat pumps which do not operate all year round. In the case you
operate your heat pump all year round and/or also in winter months when ambient air temperature
decreases below 0°C it is necessary to ensure continuous water circulation through the water heat
exchanger with water of temperature at least 20°C. In the case this is not done, water inside the
water heat exchanger may cool down and subsequently freeze up which causes destructive damage
to heat exchanger and the heat pump will no longer be operational. Warranty excludes such damage.
Winterizing:
1.
Disconnect the heat pump from the mains (e.g. by turning the circuit breaker off).
2.
Close the bypass valves number 2 and 3 (Please refer
to section 4.2 Connection to water
filtration circuit).
3.
Make sure that the heat pump is disconnected from the mains (electricity). Do not
continue if the heat pump still has power supply or shows signs of it.
4.
Drain the exchanger through the ‘DRAINAGE’ screw on the side of the exchanger. It is advised
to unscrew one 6/4 hose nut to allow air enter the exchanger.
