Electric connection

Connect the unit after checking the panel components.
ATTENTION
Connection to the electric line shall be effected applying a suitable safety device (a
circuit breaker or a ground fault interrupter) selected by the installer on the basis of
the line involved and of the absorption indicated on the unit plate.
If a cold room includes more units, each unit shall be provided with its own safety device.

This connection is only necessary if the unit has a water-cooled condenser. It is effected by following the
indications of the tags positioned by the inlet and outlet pipes. Connection pipes should never be smaller in
diameter than those on the unit. A minimum water pressure of 1 bar is required for correct operation of the
unit.

7.3 Connection to humidifier system

Connect humidifier water supply pipe: it is necessary to use a pipe with a diameter of at least 10mm.,
and pressure in the water circuit must be between 1.5 and 3.0 ATM.
Install a pressure reducer and a filter before water inlet.
