Installation
For proper installation, consider the
following:
Unit nameplate
The unit nameplate gives the full model
reference. The operating voltage must
be as specified and must not vary by
more than 6%.
Foundation
Ensure the floor to foundation of the
unit is level, solid and of sufficient
strength to support the unit weight.
Level the floor if necessary before
placing the unit. Please refer to
(General Specification) for information
on weights.
Clearances
Provide sufficient clearance around the
unit. Please refer to the section on
dimensions for recommended service
are required.
The service envelope
shown is the minimum required for
general maintenance of fans and
refrigerant components. The
minimum room required to remove
fans, fan motor, compressors and
condensers was considered.
However, the service envelopes
provided do not include space required
for change of shaft or removal of coils
or local electrical codes.
Piping
The installer must furnish and install a
condenser main and standby water
pump, cooling tower, pressure gauges,
strainers and all components for
waterside piping. All field installed
piping must conform to applicable local
codes. Recommended piping
components is provided in figure 2, to
ensure proper, clean and serviceable
supply.
Air Filters
Please refer to unit dimension al data
for information on filter layout.
Condensate drain
connections
Connect drain piping to a 1-1/4 inch
fitting. Piping should be no smaller than
7/8 inch-OD copper or ¾ inch iron pipe.
Pitch the line away from the drain pan
and install a P-trap.
Vibration Isolation
All units will be shipped with rubber-
in-shear isolators at the base which
holds the compressors. For further
vibration and acoustic isolation, it is
recommended to install neoprene
rubber padding along the perimeter of
the unit base.
Refrigerant Circuit
Single manifolded circuit on WCVS
270,WCVS 330 and WCVS 400.
Two manifolded circuits on WCVS 470-
800.
Manifolded circuits will have two
compressors manifolded.
Figure 3 shows a typical manifolded
circuit for WCVS.
