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.
SAFETY INSTRUCTIONS
The following symbols and labels are used throughout
this manual to indicate immediate or potential safety
hazards. It is the owner's and installer's responsibility to
read and comply with all safety information and instructions
accompanying these symbols. Failure to heed safety
information increases the risk of personal injury, property
damage, and/or product damage.
