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.
HOFFMAN ENCLOSURES INC. cannot accept responsibility for freight damages; however, we
are ready to assist you in any way possible. For assistance, call or write:
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.
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.
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.
