INTRODUCTION
This installation manual applies to Hoffman 2000 and 4000 BTU/HOUR PROLINE air conditioners. Consult the
label and specific design data for electrical requirements.
The standard air conditioning units are intended for indoor use in non−corrosive atmospheres, operating at
ambient temperatures from 50 F (10 C) minimum to 125 F (52 C) maximum. Operation outside this range without
prior modification or approval from Pentair Equipment Protection will void the warranty.
For applications where the ambient will be below 50 F (10 C), consult the factory.
CAUTION
• Read this manual thoroughly before attempting to install this air conditioner. Failure to do so may result
in damage to the unit or other enclosure equipment.
• The air conditioner power source should be electrically isolated from all other sources to the enclosure
equipment. This is particularly important if any of the equipment is susceptible to noise or voltage
fluctuations which may be encountered during air conditioner start up.

RECEIVING THE AIR CONDITIONER
Inspect the air conditioner. Check for concealed damage that may have occurred during shipment. Look for dents,
scratches, loose assemblies, evidence of oil, etc. Damage evident upon receipt should be noted on the freight bill.
Damage should be brought to the attention of the delivering carrier -- NOT to Pentair Equipment Protection -within 15 days of delivery. Save the carton and packing material and request an inspection. Then file a claim with
the delivering carrier.
Pentair Equipment Protection cannot accept responsibility for freight damages; however, we will assist you in any
way possible.
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.
CAUTION
NEVER attempt to operate the air conditioner while in any other
position than the operating position. Running the refrigeration
compressor without oil in the lower part of the housing will cause
permanent damage to the unit. This also voids the warranty.
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.
When ordering service parts, specify the
catalog number 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 on page 3 and label
information for full load amp rating and
Wiring Schematic on page 8 for specific
model. Follow all applicable electrical codes.
Leak test pressures.
