TO THE INSTALLER
Before installing this unit, please read this manual to familiarize yourself on the specific items which must be adhered to,
including maximum external static pressure to unit, air temperature rise, minimum or maximum CFM and motor speed connections.
IMPORTANT NOTE: If a crankcase heater is used, the unit should be energized 24 hours prior to compressor start up to ensure
crankcase heater has sufficiently warmed the compressor. Compressor damage may occur if this step is not followed.
TO THE OWNER
A warranty certificate is provided with the unit. Read the warranty carefully and note what is covered. Keep the warranty
certificate in a safe place so you can find it when necessary.
SHIPPING INSPECTION
Upon receiving the unit, inspect it for damage from shipment. Claims for damage, either shipping or concealed, should be filed
immediately with the shipping company. Check the unit model number, specifications, electrical characteristics and accessories to
determine if they are correct. In the event an incorrect unit is shipped, it must be returned to the supplier and must NOT be
installed. The manufacturer assumes no responsibility for installation of incorrectly shipped units.
