7.9 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).
7.10 Evaporator water ow-rate
Check that the dierence 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 ow rate (L/h)
The cooling power is shown in the table of the GENERAL TECHNICAL DATA included in this manual, referred to specic 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 ow rate
measure the dierence 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.
7.11 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 dierent electric loads (compressors, fans, pumps etc)
temperatures and ows of the dierent 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.
7.12 Operating at reduced load
The units are equipped with partialization steps and they can, therefore, operate with reduced loads.
However a constant and long operation with reduced load with frequent stop and start-up of the compressor/s can cause serious damages
for the lack of oil return.
The above-described operating conditions must be considered outside the operating limits.
In the event of compressor breakdown, due to operating in the above-mentioned conditions, the guarantee will not be valid and Clivet spa
declines any responsibility.
Check periodically the average operating times and the frequency of the compressors starts: approximately the minimum thermal load
should be such as to need the operating of a compressor for at least ten minutes.
If the average times are close to this limit, take the proper corrective actions.
7.13 97/23 CE PED directive
97/23 CE PED DIRECTIVE gives instructions for installers, users and maintenance technicians as well.
Refer to local regulations; briey and as an example, see the following:
Compulsory verication of the rst installation:
only for units assembled on the installer’s building site (for ex. Condensing circuit + direct expansion unit)
Certication of setting in service:
for all the units
Periodical verications:
to be executed with the frequency indicated by the Manufacturer (see the “maintenance inspections” paragraph)
