Checklist
WARNING
Fiberglass Wool!
Product contains fiberglass wool. Disturbing the insulation 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 California to cause cancer through inhalation. Glass wool fibers
may also cause respiratory, skin or eye irritation.
Jobsite Inspection
Always perform the following checks before accepting a unit:
1. Verify that the nameplate data matches the data on the sales order and bill of
lading (including electrical data).
2. Verify that the power supply complies with the unit nameplate specifica-
tions.
3. Visually inspect the exterior of the unit, for signs of shipping damage. Do not
sign the bill of lading accepting the unit(s) until inspection has been com-
pleted. Check for damage promptly after the unit(s) are unloaded. Once the
bill of lading is signed at the jobsite, the unit(s) are now the property of the
SOLD TO party and future freight claims MAY NOT be accepted by the
freight company.
4. Verify that the refrigerant charge has been retained during shipment by use
of gauges. Schrader taps are located external to the cabinet on the 2-ton
through 6-ton equipment.
5. After assuring that charge has been retained, reinstall the schrader caps to
assure that refrigerant leakage does not occur.
WARNING
Microbial Growth!
Wet interior unit insulation can become an amplification site for
microbial growth (mold), which may cause odors and damage to the
equipment and building materials. If there is evidence of microbial
growth (mold) on the interior insulation, the insulation should be
removed and replaced prior to operating the system.
Jobsite Storage
This unit is intended for indoor use only. To protect the unit from damage due to
the elements, and to prevent possible IAQ contaminant sources from growing,
the unit should be stored indoors. If indoor storage is not possible, the following
provisions for outdoor storage must be met:
1. Place the unit(s) on a dry surface or raise above the ground to assure ade-
quate air circulation beneath the unit.
2. Cover the unit(s) with a water proof tarp to protect them from the elements.
3. Make provisions for continuous venting of the covered units to prevent
moisture from standing on the unit(s) surfaces. Wet interior unit insulation
can become an amplification site for microbial growth (mold) which has
been determined to be a cause of odors and serious health related indoor air
quality problems.
4. Store units in the normal UP orientation to maintain oil in the compressor.
5. Do not stack more than three units in total height for the WPWD/GSWD 2-ton
through 6-ton configurations, and no more than two units high for the EXWA
20-ton configuration.
