WATER CONNECTION TO THE EVAPORATOR
It is extremely important that the water inlet corresponds with the connection marked
with the writing “Water Inlet”.
Otherwise the evaporator would be exposed to the risk of freezing since the antifreeze thermostat would
not be able to perform its function; moreover the reverse cycle would not be activated in the cooling
mode, resulting in additional risks of malfunctioning.
The size and positions of the hydraulic connections are carried on the dimensional tables at the end of
the manual.
The water circuit must be set up in such a way as to guarantee that the nominal flow rate
of the water supplied to the evaporator remains constant (+/- 15%) in all operating
conditions.
The compressors often work intermittently, since the chilling requirements of the user generally do not
coincide with the output of LCX unit. In systems containing little water, where the thermal inertia of the
water is lower, it is a good idea to check that the water content in the section delivering to users satisfies
the condition below:
