INSTALLATION

Receiving and Inspection
Upon receiving the product, verify that all pieces listed on
the bill of lading, delivery receipt, or packing list have
been received.
Inspect each crate or carton for shipping damage before
accepting delivery. Alert the carrier if any damage is
detected; do not refuse shipment. The customer must
note any damage (or shortage of items) on the delivery
receipt and all copies of the bill of lading, which then
should be signed by the delivery carrier. Photograph the
damage if possible. If damaged, immediately contact your
manufacturer's representative.
Handling
Handle in such a manner as to keep from scratching or
chipping the unit.
Storage
Units are protected against damage during shipment. If
the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the unit and accessories while in storage. The
manufacturer will not be responsible for damage during
storage. These suggestions are provided solely as a
convenience to the user.
The ideal environment for the storage of units and
accessories is indoors, above grade, in a low humidity
atmosphere which is sealed to prevent the entry of
blowing dust, rain, or snow. All accessories must be
stored indoors in a clean, dry atmosphere
Removing from Storage
As units are removed from storage to be installed in their
final location, they should be protected and maintained
in a similar fashion until the equipment goes into
operation.
Prior to installing the unit and system components,
inspect the unit assembly to make sure it is in working
order.
1. Check all fasteners, set screws on the fan, wheel,
bearings, drive, motor base, and accessories for
tightness
2. Rotate the fan wheel(s) by hand and assure no
parts are rubbing.

Location Selection
DANGER
To avoid the possibility of fire, do not install the unit in an
area where combustible gas may generate, flow,
stagnate, or leak. Failure to do so will cause serious
bodily injury or death. Before beginning installation, read
the safety summary at the beginning of this manual.
Note:
Select a location for installing the unit that meets the following
conditions:
1.
Where there is enough structural strength to bear the weight
of the unit.
2. Operating sound from the unit will not disturb occupants.
3. Include enough space for service access.
4. Include space for drainage to ensure condensate flows
properly out of the unit when it is in cooling mode.
5. Use a level indicator to ensure the unit is installed on a level
plane.
Note:
The unit may be damaged, may malfunction, and/or will
not operate as designed if installed in any of these
conditions.
1. Do not install the unit near a heat or steam source or
where considerable amounts of oil, iron powder, or flour
are used. These materials may generate condensate,
cause a reduction in heat exchanger efficiency, or
malfunction of the condensate drain. If this is a potential
problem, install a ventilation fan large enough to vent out
these materials
2.Do not install the unit where it will be subjected to direct
thermal radiation from other heat sources
