When replacing the power cable, the earth
conductor must be kept longer than the active
conductors.

Condensing unit water connection
The chiller cabinets with water condensation have
been designed to use normal tap water.
Connect the mains pipe to the appliance
connection pipe, positioning a shut-off cock (A) to
interrupt the water supply when necessary. Install
some easily reachable filters downstream from this.
The water pressure must be between
150÷300 kPA (1.5÷3 bar).
!
Attachment to the water network must be
carried out before switching the appliance on: if
cooling is missing from the condensing circuit, the
maximum pressure switch intervenes, which
blocks the machine.
The machine must also be checked for leaks that
could interfere with electrical parts and cause
short-circuits.
It is preferable for both the water drain and supply
pipes to be fitted with cocks to stop the water
supply to the machine during maintenance.
!
The replacement of a damaged power cable
must be done by a qualified technician in order to
prevent any possible risk.

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
TABLE
(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.
