Pre-Installation Checklist
Unit Inspection
As soon as the unit arrives at the job site
[ ] Verify that the nameplate data matches the data on the
sales order and bill of lading (including electrical data).
[ ] Verify that the power supply complies with the unit name-
plate specifications.
[ ] Visually inspect the exterior of the unit, including the roof,
for signs of shipping damage.
WARNING
Fiberglass Wool !
Product contains fiberglass wool. Disturbing the insula-
tion in this product during installation, maintenance or
repair will expose you to airborne particles of glass wool
fibers and ceramic fibers known to the state of Califor-
nia to cause cancer through inhalation. Glass wool fi-
bers may also cause respiratory, skin or eye irritation.
Precautionary Measures
· Avoid breathing fiberglass dust.
· Use a NIOSH approved dust/mist respirator.
· Avoid contact with the skin or eyes. Wear long-
sleeved, loose-fitting clothing, gloves, and eye protec-
tion.
· Wash clothes separately from other clothing: rinse
washer thoroughly.
· Operations such as sawing, blowing, tear-out,
and spraying may generate fiber concentrations
requiring additional respiratory protection. Use
the appropriate NIOSH approved respiration in
these situations.
First Aid Measures
Eye Contact - Flush eyes with water to remove dust. If
symptoms persist, seek medical attention.
Skin Contact - Wash affected areas gently with soap and
warm water after handling.
If the job site inspection of the unit reveals damage or material
shortages, file a claim with the carrier immediately. Specify the
type and extent of the damage on the “bill of lading” before
signing.
[ ] Visually inspect the internal components for shipping
damage as soon as possible after delivery and before it
is stored. Do not walk on the sheet metal base pans.
[ ] If concealed damage is discovered, notify the carrier’s ter-
minal of damage immediately by phone and by mail.
Concealed damage must be reported within 15 days.
Request an immediate joint inspection of the damage by
the carrier and the consignee. Do not remove damaged
material from the receiving location. Take photos of the
damage, if possible. The owner must provide reasonable
evidence that the damage did not occur after delivery.
[ ] Notify the appropriate sales representative before install-
ing or repairing a damaged unit.
Storage
Take precautions to prevent condensate from forming inside
the unit’s electrical compartments and motors if:
a. the unit is stored before it is installed; or,
b. the unit is set on the roof curb, and temporary heat is pro-
vided in the building. Isolate all side panel service en-
trances and base pan openings (e.g., conduit holes, S/A
and R/A openings, and flue openings) from the ambient
air until the unit is ready for start-up.
Note: Do not use the unit’s heater for temporary heat
without first completing the start-up procedure
detailed under “Starting the Unit”.
The manufacturer will not assume any responsibility for
equipment damage resulting from condensate accumula-
tion on the unit’s electrical and/or mechanical components.
