6.9 Remote controls
Check that the remote controls (ON-OFF etc) are connected and, if necessary, enabled with the respective parameters as indicated in the
“electrical connections” section.
Check that probes and optional components are connected and enabled with the respective parameters (“electrical connections” section and
following pages).

6.11 Evaporator water flow-rate
Check that the difference between the temperature of exchanger return and supply water corresponds to power according to this formula:
unit cooling power (kW) x 860 = Dt (°C) x flow rate (L/h)
The cooling power is shown in the table of the GENERAL TECHNICAL DATA included in this manual, referred to specific conditions, or in the
tables on COOLING PERFORMANCE in the TECHNICAL BULLETIN referred to various conditions of use.
Check for water side exchanger pressure drops:
determine the water flow rate
measure the difference in pressure between exchanger input and output and compare it with the graph on WATER SIDE EXCHANGER
PRESSURE DROPS
The measurement of pressure will be easier if pressure gauges are installed as indicated in the DIAGRAM OF SUGGESTED WATER CONNECTIONS.
6.12 Start-up report
Identifying the operating objective conditions is useful to control the unit over time.
With unit at steady state, i.e. in stable and close-to-work conditions, identify the following data:
•
total voltages and absorptions with unit at full load
•
absorptions of the different electric loads (compressors, fans, pumps etc)
•
temperatures and flows of the different fluids (water, air) both in input and in output from the unit
•
temperature and pressures on the characteristic points of the refrigerating circuit (compressor discharge, liquid, intake)
The measurements must be kept and made available during maintenance interventions.
