Installation
Note:
Installation and maintenance must be performed
only by qualified personnel who are familiar with
local codes and regulations, trained and experi-
enced with this type of equipment.
Handling
Units may be shipped in one or two sections. When the unit
is shipped in two sections the fan section is separate from the
base sections. 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 possible.
Never allow any part of the unit to fall during unloading or
moving as this may result in serious damage. When the fan
section ships separate, lifting lugs are provided for rigging
and handling. The lugs are mounted on the fan section. If the
fan section ships attached to the base sections, lifting lugs
are not provided.
The unit base sections will accept lifting rods through chan-
nels on the base rail. 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 structural damage to the frame.
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 channel.
For units provided with more than (8) isolator pads, evenly
space the additional pads under the front and rear base chan-
nels.
Location/Service Access
For good installation, service and maintenance access the
following recommended clearances should be followed.
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 control compo-
nents and to allow for possible fan shaft or compressor
removal
.

Clearance
Removal of Shipping Restraints and
Construction Filter
Mechanical restraints are used to secure the spring mounted
fan during shipment. Restraints and shipping blocks must be
removed after unit has been set in its final location.
CAUTION
Sharp edges and coil surfaces are a potential
injury hazard. Avoid contact with them.
CAUTION
Do not attempt to install dollies in the center of
the unit.
CAUTION
Units must not be moved in an upended position.
