3 - HANDLING AND POSITIONING
3.1 - Handling
Carrier strongly recommends employing a specialised company
to unload the machine.
Do not remove the subbase or the packaging until the unit is in its
final position.
These units can be safely moved by trained personnel with a fork
lift truck with the correct capacity for the dimensions and weight
of the unit, as long as the forks are positioned in the location and
direction shown on the unit.
The units can also be lifted with slings, using only the designated
lifting points marked on the unit (labels on the chassis and a label
with all unit handling instructions, attached to the unit).
Use slings with the correct capacity, and follow the lifting instructions
on the certified dimensional drawings supplied.
IMPORTANT: Only attach slings to the designated lifting points
which are marked on the unit.
It is advisable to protect coils against crushing while a unit is being
moved. Use struts or a lifting beam to spread the slings above the
unit. Do not tilt the unit more than 15°.
Safety when lifting can only be guaranteed if all these instructions
are followed. Otherwise, there is a risk of equipment damage or
injury to personnel.
3.2 - Positioning
The machine must be installed in a place that is not accessible to
the public and is protected against access by non-authorised
persons.
The machine is designed to be installed outdoors. Moe more
details on the various installation scenarios, refer to the installation
guide for A2L refrigerants.
For extra-high units, the unit environment must permit easy access
for 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 drawings. Ensure the free space shown in
the dimensional drawings is respected to facilitate maintenance
and connection.
The typical applications of these units are cooling and heating,
which do not require earthquake resistance. Earthquake resistance
has not been verified.
Before positioning the device, check that:
- The chosen location can support the weight of the unit,
or that the appropriate reinforcement measures have been
taken.
- The unit is installed level on an even surface (maximum
tolerance is 5 mm along both axes).
- If the support structure is sensitive to vibration and/or noise
transmission it is advisable to insert anti-vibration mounts
(elastomer mounts or metal springs) between the unit and
the structure. Selection of these devices is based on the
system characteristics and the comfort level required and
should be made by technical specialists.
- There is adequate space above and around the unit
for air to circulate and for access to the components
(see dimensional drawings).
- the number of support points is adequate and that they are
in the right places.
- the location is not subject to flooding.
- Avoid installing the unit where snow is likely to accumulate
(in areas subject to long periods of sub-zero temperatures,
the unit should be raised).
- The unit must be installed on a plinth designed to collect then
drain the water produced by the reversible units during the
defrost cycles

- The wind may affect the operation and performances of
machines. Baffles may be necessary to deflect strong winds.
These must not restrict the unit's air flow.
IMPORTANT: Before lifting the unit, check that all enclosure
panels and grilles are securely fixed in place. Lift and set
down the unit with great care. Tilting and jarring can damage
the unit and impair unit operation.
Never apply pressure or leverage to any of the unit's panels
or uprights; only the base of the unit frame is designed to
withstand such stresses. No force or effort must be applied
to pressurised parts, especially via pipes connected to the
water type heat exchanger (with or without the hydraulic
module if the unit is equipped with this). The hydraulic module
pipes must be fitted so that the pump does not support the
weight of the pipes.
All welding operations (connection to the hydraulic network) must
be performed by qualified welders. The Victaulic
the counter-flange must be removed before welding as a matter
of course.
Specific data 30RQ/30RQP
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.
