Installation; Handling; Vibration Isolators; Setting Factory Supplied Plenum - McQuay SWP 018 Installation And Maintenance Manual

Installation

Note: Installation and maintenance are to be performed
only by qualified personnel who are familiar with
local codes and regulations, and experienced with
this type of equipment.
CAUTION
Sharp edges and coil surfaces are a potential injury hazard.
Avoid contact with them.

Handling

Units are shipped with a protective covering which should
remain in place while the unit is being moved to its final
location. Note: Check for concealed damage as soon as pos-
sible.
Never allow any part of the unit to fall during unloading or
moving as this may result in serious damage. Units are pro-
vided with lifting lugs for rigging with a crane. If units are
lifted by crane, protection against chaffing damage by slings
or cable must be provided and spreader bars must be used
across the top of the cabinet to prevent any structural damage
to the frame.
The unit base frame will accept dollies or Johnson bars for
transporting the unit. Furniture dollies can be placed at both
ends of the chassis or at one end and a Johnson bar used at
the other end for maneuvering.
CAUTION
Do not attempt to install dollies in the center of the unit.
CAUTION
Units must not be moved in an upended position.
Floor surfaces must be protected when equipment is moved
across finished flooring. Plywood sheeting may be used to
protect surfaces and distribute weight loading.

Vibration Isolators

All units are provided with 1" neoprene isolation pads,
shipped separately. Pads are to be installed beneath the unit
and located at each corner and the center of each base chan-
nel. For units provided with more than six (6) isolator pads,
evenly space the additional pads under the front and rear
base channels.

Setting Factory Supplied Plenum

If the unit is provided with a factory plenum for field mount-
ing, a forklift, slings or other suitable lifting means is
4
required. Foam rubber gasket is provided around the perime-
ter of unit top. Carefully set plenum. Attach with mounting
hardware provided with the plenum.

Location/Service Access

For good installation, service and maintenance access the
following recommended clearances should be followed.
Minimum clearances required by local, state, or federal
codes, such as the NEC take precedence over those listed
below. Clearance is required to allow room for side filter
access, mechanical cleaning of the condenser tubes and
economizer coil, access to expansion valves and other con-
trol components and to allow for possible fan shaft or com-
pressor removal.
Unit front - 42"
Unit rear - 24"
Motor location side - 36"
Piping location side - 36"
Side without motor or piping -24"
