6 - START-UP
Check that the air and water temperatures are included in the
working limits
For information on the control system, refer to the paragraph
CONTROL.
Start the unit
With unit of full load, namely in stable conditions and close to
those of work, check :
• Power supply tension
• Total absorption of the unit
• Absorption of the single electric loads
6.6 TENSIONS
6.8 STARTING REPORT
Realize the operating objective conditions is useful for check
the unit over time.
With unit of full load, namely in stable conditions and close to
those of work, take the following data:
• Tension and general absorptions with unit at full load
• Absorption of varied electrical loads (compressors, fans,
pumps etc)
• Temperatures and capacities of different liquid (water, air)
in the inlet and outlet of the unit
• Temperatures and pressures on the refrigerant circuit
characteristic points (compressor discharge, liquid, intake)
The remarks should be preserved and available during
maintenance .
97/23 CE PED DIRECTIVE gives instructions for installers,
users and maintenance technicians as well.
Refer to local actuation norms; briefly and as an example, see
the following
• Compulsory verification of the first installation :
only for units assembled on the installer’s building site
(for ex. Condensing circuit + direct expansion unit)
• Certification of setting in service :
for all the units
• Periodical verifications:
to be executed with the frequency indicated by the
manufacturer (see the maintenance section)
6.9 CE 97/23 PED DIRECTIVE
• Check that the remote commands (ON-OFF, etc.) are
connected and if necessary enabled with the relevant
parameters as described in ELECTRICAL
CONNECTIONS section
• Check that probes or optional components are connect
and enable with the relative parameters( ELECTRICAL
CONNECTION section)
