7.14 Fire alarm: configuration
It is possible to configure the unit behaviour in presence of alarm signal.
Par 1.11 TypeFireMode
The unit cannot be used as smoke extractor.
Any fire detection devices built-in the unit must be considered as an auxiliary safety system, and, accordingly, must not be a replacement for
any fire detection devices in the room.
7.15 Room pressure calibration
CCK configurations
1. check the doors and windows of the serviced room are closed
2. calibration must be carried out with unit all in recirculation
3. view the status on the display: Pf2 RETURN AIR PRE
4. wait for the pressure value to stabilise and take note of the value
5. to keep the room at neutral pressure, memorise the value of the read pressure in 5.07 SetPAmb
6. to maintain the room in overpressure, memorise a higher value respect to that detected
7. to maintain the room in depression, memorise a lower value
7.16 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.
7.17 2014/68/UE PED directive
DIRECTIVE 2014/68/UE PED gives instructions for installers, users and maintenance technicians as well.
Refer to local regulations; 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 c 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 inspections” paragraph)
