Check the following:
n
The temperature of the water entering the evapora-
tor.
n
The temperature of the water leaving the evapora-
tor.
n
The level of the water flow rate in the evaporator, if
possible.
n
The current absorption upon the start of the com-
pressor and in case of stabilised operation.
n
The fan’s current absorption.
Check that the condensing and evaporation tempera-
tures, during operation at high and low pressure de-
tected by the pressure gauges of the refrigerant, are
within the following range:
(On the units not provided with HP/LP pressure gaug-
es for the refrigerant, connect a pressure gauge to the
Shrader valves on the refrigeration circuit).
