Check compressor mountings
Before the first start-up of the unit proceed as follows:
All compressors are mounted on anti-vibration mountings. For
the 30GH/GZ 040-060 units, please do not loosen the bolts or
fixing screws.
For 30GH/GZ 085-245 units
The compressors are mounted on anti-vibration mountings. For
shipping purposes these are packed solid with wedges, angle
pieces and retaining bolts. These must be removed, when the
installation is completed to allow the vibration absorbing
mountings to do their job (see figure below).
Preliminary checks
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 nameplate data with the order.
•
Confirm that all accessories ordered for on-site installation
have been delivered, and are complete and undamaged.
Moving and siting the unit
Moving
Do not remove skids, pallets or protective packaging until the
unit is in its final position. Move the chiller using tubes or
rollers, or lift it, using slings of the correct capacity.
CAUTION: Only use slings at the designated lifting points
which are marked on the unit.
Siting
Before siting the unit check that :
•
the permitted loading at the site is adequate or that
appropriate strenghtening measures have been taken.
•
the surface is horizontal, flat and intact.
•
there is adequate space around the unit to make power and
water connections for service and air flow.
•
there are adequate support points and that they are in the
right places.
•
the location is not subject to flooding.
•
where heavy snowfall is likely and long periods of sub-
zero temperatures are normal, provision has been made to
prevent snow accumulating by raising the unit above the
height of drifts normally experienced.
Baffles may be necessary to deflect strong winds and to
prevent snow from blowing directly into the unit. 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.
The 30GH/GZ units can be hoisted with rigging. Coils should
always be protected 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.
