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.
• Compare the name plate data with the order. The name plate
is attached in two places to the unit:
- On one of the unit sides on the outside,
- On the control box door on the inside.
• The unit name plate must include the following information:
- Address of manufacturer
- Version number
- Model number
- CE marking
- Serial number
- Year of manufacture and test date
- Fluid being transported
- Refrigerant used and refrigerant class
- Refrigerant charge per circuit
- Containment fluid to be used
- PS: Min./max. allowable pressure (high and low pressure
side)
- TS: 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 drawn
- Maximum power input
- Unit net weight
• Confirm that all accessories ordered for on-site installation
have been supplied, are complete and undamaged.
The unit must be checked periodically during its whole
operating life to ensure that no shocks (handling accessories,
tools etc.) have damaged it. If necessary, damaged parts must
be repaired or replaced. See also chapter 12 - "Standard
maintenance".
2.2 - Moving and siting the unit
2.2.1 - Moving
See chapter 1.1 "Installation safety considerations".
In some cases vertical supports are added for the transport and
handling of the unit. These supports can be removed for access
or connection, if required.
IMPORTANT: Follow the disassembly sequence shown in the
disassembly instruction notes.
NOTE:
- Screw off item: 1
- Loosen screw item: 2
- Raise and remove frame post item: 3
- Screw off item: 4 and remove reinforcement plate item: 5
- Keep the vertical supports after commissioning the units
and re-insert them when the unit is moved.
See the slinging plan for each machine in appendix 4.

2.2.2 - Siting the unit
The machine must be installed in a place that is not accessible to the
public or protected against access by non-authorised persons.
The unit is not intended to be used in ATEX zone.
The unit must be installed in outdoor and open space. Condenser
air flow shall not be restricted for proper unit operation.
In case of extra-high units the machine environment must
permit easy access for maintenance operations.
Always refer to the chapter 3 "Dimensions, clearances" to confirm
that there is adequate space for all connections and service
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 support points under the chassis must have at least the size
of the chassis opening at the lifting point (minimum 220 x 180 mm)
in order to prevent a deformation of the chassis.
Typical applications of these units are in refrigeration systems,
and they do not require earthquake resistance. Earthquake
resistance has not been verified.
CAUTION: Only use slings at the designated lifting points
which are marked on the unit.
(See also chapter 3 for information about slinging points)
