UNPACKING AND INSPECTION
Inspect the industrial air conditioner by checking for concealed damage that may have occurred
during shipment. Look for dents, scratches, loose assemblies, evidence of oil, etc. Any evident
damage upon receipt should be noted on the freight bill. Damages should be brought to the
attention of the delivering carrier within 15 days of delivery, NOT to HOFFMAN ENCLOSURE
INC. If damage is evident, save all packaging materials and request the carrier to inspect the
product prior to filing a claim with the carrier.

PRODUCT HANDLING
To avoid possible shipping damage and facilitate transportation and storage, the industrial air
conditioner may have been shipped in a vertical position. If it is necessary to place the air
conditioner in a vertical position after removing from carton, be certain it is placed in an upright
(horizontal) or mounting position for a minimum of five (5) minutes before operating, in order to
allow the compressor oil to drain to the compressor sump area.
PRODUCT IDENTIFICATION
For installation and maintenance as outlined in this manual, first refer to the nameplate on your
unit. The nameplate will provide important data regarding capacity of the unit, minimum and
maximum ambient operating temperatures, type and amount of refrigerant required for
recharging, and electrical power characteristics when making electrical hookups or connections.
CAUTION
NEVER attempt to operate the air conditioner while in any other position than the operat-
ing position. Running the refrigeration compressor without oil in the lower part of the hous-
ing will cause permanent damage to the unit. This also voids the warranty.
When ordering service parts, specify the catalog or job number and
serial number.
Before installing, make certain these parameters are met. Lower
or higher ambient temperatures may cause permanent damage or
malfunction of the unit.
Before operating, make certain outlet and power source match
these requirements.
Refer to ”Design Data” (page 3) and label information for full load
amp rating and ”Wiring Schematic” (page 9) for specific model.
Follow all applicable electrical codes.
Leak test pressures.
