Moving And Siting The Unit; Moving; Siting The Unit - Carrier AquaSnap 30RB Series Installation, Operation And Maintenance Instructions

Periodically inspect all valves, fittings and pipes of the
refrigerant and hydronic circuits to ensure that they do
not show any corrosion or any signs of leaks.
It is recommended to wear ear defenders, when working
near the unit and the unit is in operation.

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 must be removed
for access or connection, if required.
IMPORTANT: follow the disassembly sequence shown
in the disassembly instruction notes.
• Unscrew screws marked 1 and 2
• Loosen screw 3, and lift and remove support 4
• Uncrew screw 5 and loosen screw 6.
• Lift and remove support 7.
• Unscrew screw 8 and remove plate 9.

Keep the vertical supports after commissioning the units
and re-insert them when the unit is moved.

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.
In case of extra-high units the machine environment must
permit easy access for maintenance operations.
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
distribution points, refer to the certified dimensional
drawing supplied with the unit.
Typical applications of these units 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.
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 (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.
• 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 30RB units are hoisted with rigging, 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 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.
If a unit includes a hydronic module (options 116B, C, f,
g, M, N P, Q), the hydronic module and pump piping must
be installed in a way that does not submit it to any strain.
The hydronic module pipes must be fitted so that the pump
does not support the weight of the pipes.
