Warranty does not cover any product, property or personal damages or
losses that are a result of incorrect flaring work, gas leakage, incorrect
welding work or improper material used.
When cutting the pipes and cables, please mind the following:
1. Measure the distance between the water and the condensing unit.
2. Cut the pipes a little longer than measured distance.
3. Cut the cable 1.5m longer than the pipe length.
Pressure test / Air purging
Sometimes bits of air and moisture remains in the refrigerant circuit. If this is not treated, following
symptoms may appear on your heat pump:
1.
Pressure in the system rises.
2.
Operating current rises.
3.
Heating or cooling efficiency drops.
4.
Blockage of capillary tube due to frozen moisture resulting in complete failure of the heat
pump.
5.
Corrosion of refrigerant circuit.
It is thus highly advised to take a leak test after evacuating the complete sys

by most commonly applied methods with vacuum pump. This Installation and user manual elaborates
