WSHP-SVX02A-EN

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.
