2.9. WATER CONDENSING UNIT CONNECTION
•
•
• During inspection of the water network, with the machi-
ne stopped and the water mains ready, check that the
drain tube of the condenser does not leak water. If it
does, adjust the pressure switch valve until leaking
stops (Fig.13).
It is recommended to install a water gate and an inspec-
tion filter on the water delivery line. The delivery and
drain tube of the condenser are indicated by the appro-
priate plates. Both connections are 3/8”F threaded.
See
Table 7

Checking a correct installation and inspection:
Check for gas leaking from seals or joints made during
installation.
Check that the connection tubes between the conserver
and the remote condensing unit are well insulated.
Check the electrical connections.
Check the absorptions.
Check the standard pressures.
Check the water connection with the adjustment of the
pressure switch valve during operation and that conden-
sation water circulates well.
Inform the customer on the exact use of the equip-
ment, with specific reference to the use and needs of the
customer.
Installation and commissioning must be carried
out by authorised personnel.

Table 7
The safety devices must be installed in such a way that
leakage of refrigerant cannot cause any danger. When
installing the pressure release piping of the safety valves,
the line must comply with local standards.
For loads with more than 100 kg of refrigerant, adequate
overflow devices must be installed by the installer as
foreseen by the standard EN378-2:2008+A1:2009 ANNEX F.
