The temperature of the water entering the evapo-
rator.
Q
The temperature of the water leaving the evapora-
tor.
Q
The level of the water flow rate in the evaporator,
if possible.
Q
The current absorption upon the start of the com-
pressor and in case of stabilised operation.
Q
The fan’s current absorption.
Check that the condensing and evaporation tempe-
ratures, during operation at high and low pressure
detected by the pressure gauges of the refrigerant,
are within the following range:
(On the units not provided with HP/LP pressure gau-
ges for the refrigerant, connect a pressure gauge to
the Shrader valves on the refrigeration circuit).
5.4 Delivery to the customer
Q
Train the user according to the instructions provi-
ded in Section 6.
