Both water inlet and drain pipe connections are
3/4”. To know which attachment to use (both 3/4”),
simply follow the indications in the figure (the
same label should be found near the water supply
connections).
If the water has a high mineral salt content
(i.e. if it is too hard), to ensure long and efficient
life to the exchanger we suggest you install a
water softener at the water inlet.
Even if the pressure valve has been calibrated
before leaving the factory, after having connected
the machine to the water supply and turned on the
any cocks installed, check for water leaks from the
drain when the machine is at a standstill. In case
of a leak, adjust the pressure valve until the leak
stops.
8.5. Remote condensing unit
!
When installing a remote condensing unit,
the same precautions must be taken as for the
installation of the machine with an integrated
condensing unit. In particular, it is important to
respect the electric installation rules, the fire-
prevention rules and to keep in mind that under
certain circumstances coolant gas may be
released into the environment (it must be possible
to air the room).
Performance is guaranteed for remote unit
installations up to a distance of 10 m and with an
insulated intake line (insulation must be at least
13 mm thick).
The recommended pipes are given in the
attachments.
Both the condensing unit and the coolant
circuit are under pressure using nitrogen therefore
the seal of the circuits can be checked when
turning on the cocks.
After having connected the delivery and intake
pipes and having created a vacuum and then
loaded the pipes, make sure that the welded parts
are hermetically sealed and that there are no
leaks.
The gas load must be checked through the gas
conduit indicator located on the condensing unit.
For installations on the same level or different
level follow the indications in the figure.
In particular, if the remote unit is installed higher,
a siphon is created at every departure/arrival or
re-ascent, while if the unit is installed lower no
siphon is necessary.
