3. Forming and insulation the piping.
The pipes must be insulation and secured
with vinyl tapes. This is done in order to
prevent condensation on the piping.
It is highly advised to place the piping into
a plastic protector when installed in the
ground (soil).
On places where piping goes through a
wall or similar it is advised to use gum type
sealer or construction foam to seal the
openings.
3.1. Condensing unit below water unit
Tape the piping and interconnecting cable
from down upwards. Fix the tapped piping
with cable binder or equivalent onto the
exterior wall. It is important to make a trap
to prevent water from entering into the
electro installation of the condensing unit.
3.2 Condensing unit above water unit
Tape the piping and interconnecting cable
from down upwards. Fix the tapped piping
with cable binder or equivalent onto the
exterior wall. It is important to make a trap
to prevent water from entering into the
electro installation of the condensing unit.
On refrigerant side it is important to form
a syphon.
4.6
Flaring work
It is important to perform the flaring work correctly. This will have positive effect towards long-term
reliability and functionality of the heat pump. Defective or incorrect flaring work is the most common
cause for gas leakage. Gas leakage results in continuous decrease of heat pump efficiency and
eventually leads into security turning off, malfunction, failure or damage.
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.
