Moving And Siting The Unit - Carrier Pro-Dialog Plus 30HZ Installation, Operation And Maintenance Instructions

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 dis-
tribution points, refer to the certified dimensional drawing
supplied with the unit.
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.
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 to ensure access
to the components for maintenance.
• the number of support points is adequate and that
they are in the right places.
• the location is not subject to flooding.
CAUTION: Lift and set down the unit with great care.
Tilting and jarring can damage the unit and impair unit
operation.
If 30hZ/hZV units are hoisted with rigging, it is advis-
able to protect the control box against accidental shocks.
Do not tilt a unit more than 15°.
WARNINg: Never push or lever the chassis or the control
box of the unit.
Checks before system start-up
Before the start-up of the refrigeration system, the complete
installation, including the refrigeration system must be
verified against the installation drawings, dimensional
drawings, system piping and instrumentation diagrams and
the wiring diagrams.
During the installation test national regulations must be
followed. If no national regulation exists, paragraph 9-5 of
standard EN 378-2 can be used as a guide.
External visual installation checks:
• Compare the complete installation with the refrigera-
tion system and power circuit diagrams.
• Check that all components comply with the design
specifications.
• Check that all safety documents and equipments that
are required by current European standards are
present.
• Verify that all safety and environmental protection
devices and arrangements are in place and comply
with the current European standard.
• Verify that all document for pressure containers, cer-
tificates, name plates, files, instruction manuals that are
required documents required by the current European
standards are present.
• Verify the free passage of access and safety routes.
• Check that ventilation in the special plant room is
adequate.
• Check that refrigerant detectors are present.
• Verify the instructions and directives to prevent the
deliberate removal of refrigerant gases that are harmful
to the environment.
• Verify the installation of connections.
• Verify the supports and fixing elements (materials,
routing and connection).
• Verify the quality of welds and other joints.
• Check the protection against mechanical damage.
• Check the protection against heat.
• Check the protection of moving parts.
• Verify the accessibility for maintenance or repair and
to check the piping.
• Verify the status of the valves.
• Verify the quality of the thermal insulation and of the
vapour barriers.
2.2.3 - Check compressor mountings
Before any start-up of the unit proceed as follows:
For 30hZ/hZV 043-065 units
1. Remove the wooden block located under the compres-
sor foot.
2. Remove the screw and washer used for transportation.
3. Assemble screw (A), snubber (B) and plain washer (C).
For 30hZ/hZV 091-280 units
Remove the centre bolt (A) from each spring mounting, so
that the compressor support can float freely.
