5.3 Checking the operation
Check the following:
h
The temperature of the water entering the evapo-
rator.
h
The temperature of the water leaving the evapora-
tor.
h
The level of the water flow rate in the evaporator,
if possible.
h
The current absorption upon the start of the com-
pressor and in case of stabilised operation.
h
The fan’s current absorption.
Check that the condensing and evaporation temper-
atures, 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
gauges for the refrigerant, connect a pressure gauge
to the Schreader valves on the refrigeration circuit).
5.4 Delivery to the customer
h
Train the user according to the instructions provid-
ed in Section 6.
HP side Approx. 15 to 21°C above the
temperature of the air entering the
condenser, for R407C units.
LP side Approx. 2 to 4°C below the tem-
perature of the leaving chilled wa-
ter, for R407C units.
