Before siting the unit check that:
• the permitted loading at the site is adequate or that
appropriate strenghtening measures have been taken.
• the unit is installed level on an even surface (maximum
tolerance is 5 mm in both axes).
• there is adequate space above the unit for air flow and to
ensure access to the components.
• the number of support points is adequate and that they are
in the right places.
• the location is not subject to flooding.
• for outdoor installations, where heavy snowfall is likely
and long periods of sub-zero temperatures are normal,
provision has to be made to prevent snow accumulating
by raising the unit above the height of drifts normally
experienced. Baffles may be necessary to deflect strong
winds. They must not restrict air flow into the unit.
CAUTION: Before lifting the unit, check that all casing
panels 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.
If 30GX units are hoisted with rigging, it is advisable to protect
coils against crushing while a unit is being moved. Use struts
or spreader bars to spread the slings above the unit. Do not tilt
a unit more than 15°.
WARNING: Never push or lever on any of the enclosure
panels of the unit. Only the base of the unit frame is designed
to withstand such stresses.
2 - PRELIMINARY CHECKS
2.1 - Check equipment received
• Inspect the unit for damage or missing parts. If damage is
detected, or if shipment is incomplete, immediately file a
claim with the shipping company.
• Confirm that the unit received is the one ordered. Compare
the name plate data with the order.
• Confirm that all accessories ordered for on-site installation
have been delivered, and are complete and undamaged.
• Do not keep the 30HXC units outside where they are
exposed to the weather, as the sensitive control mechanism
and the electronic modules may be damaged.
2.2 - Moving and siting the unit
2.2.1 - Moving
See chapter 1.1 "Installation safety considerations".
2.2.2 - Siting the unit
Always refer to the chapter "Dimensions and 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 distribu-
tion points, refer to the certified dimensional drawing supplied
with the unit.
CAUTION: Only use slings at the designated lifting points
which are marked on the unit.
