2 - PRELIMINARY CHECKS
2.1 - Check equipment received
•
Check that the unit has not been damaged during transport
and that no parts are missing. If the unit has been damaged
or the shipment is incomplete, send a claim to the shipping
company.
•
Check the unit's nameplate to ensure it matches the model
ordered. The nameplate is attached in two places to the unit:
-
On the outside of one of the unit frames,
-
On the inside of the electrical panel door.
•
The unit nameplate must include the following information:
-
Model number - size
-
CE marking
-
Serial number
-
Year of manufacture and pressure and leak tightness
test date
-
Fluid used for transport
-
Refrigerant used
-
Refrigerant charge per circuit
-
OP: Min./max. allowable pressure (high and low
pressure side)
-
OT: Min./max. allowable temperature
-
(high and low pressure side)
-
Pressure switch cut-out pressure
-
Unit leak test pressure
-
Voltage, frequency, number of phases
-
Maximum current
-
Maximum input power
-
Unit net weight
•
Confirm that all accessories ordered for field installation
have been delivered in perfect working order.
The unit must be checked periodically, if necessary removing
the insulation (thermal, acoustic), throughout its service life
to ensure that nothing has damaged the unit (handling
equipment, tools, etc.). If necessary, damaged parts must be
repaired or replaced. See also the section on "Maintenance" .

2.2 - Handing and positioning
2.2.1 - Handling
See the section on "Installation safety considerations" .
In some cases, uprights are added for transporting and handling
the unit. The uprights must be removed if necessary for access
or connection.
Important: follow the disassembly procedure indicated in the
disassembly instructions.
•
Undo the bolt (3).
•
Remove the upright (2).
•
Remove the plate (1).
Keep the uprights following start-up and refit them when moving
the unit.
2.2.2 - Positioning within the installation area
The machine must be installed in a place that is not accessible to
the public or protected against access by non-authorised persons.
If the unit is to be raised, ensure the machine's surroundings
permit easy access for maintenance operations.
Always refer to the "Dimensions and clearances" section to confirm
that there is adequate space for all connections and maintenance
operations. For the centre of gravity coordinates, the position of
the unit mounting holes, and the weight distribution points, refer
to the certified dimensional drawing supplied with the unit.
The typical applications of these units are heating and cooling,
which do not require earthquake resistance. Earthquake
resistance has not been verified.
CAUTION: Only attach slings at the designated lifting points
which are marked on the unit.
Before positioning the unit, check that:
•
The chosen location can support the weight of the unit, or
that appropriate reinforcement measures have been taken.
•
The unit is installed level on an even surface (maximum
tolerance is 5 mm along both axes).
