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.
• 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.
