6.7 Voltages
Check that the air and water temperatures are within in the operating limits.
Start-up the unit.
With unit operating in stable conditions, check:
•
Voltage
•
Total absorption of the unit
•
Absorption of the single electric loads
6.8 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).
6.9 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 dierent electric loads (compressors, fans, pumps etc)
•
temperatures and ows of the dierent uids (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.
6.10 97/23 CE PED directive
97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well.
Refer to local regulations; briey and as an example, see the following:
Compulsory verication of the rst installation:
•
only for units assembled on the installer’s building site (for ex. Condensing circuit + direct expansion unit)
Certication of setting in service:
•
for all the units
Periodical verications:
•
to be executed with the frequency indicated by the Manufacturer (see the “maintenance inspections” paragraph)
