TO THE INSTALLER

Carefully read all instructions for the installation prior
to installing unit. Make sure each step or procedure is
understood and any special considerations are taken into
account before starting installation. Assemble all tools,
hardware and supplies needed to complete the installa-
tion. Some items may need to be purchased locally. After
deciding where to install unit, closely look the location
over - both the inside and outside of the home. Note any
potential obstacles or problems that might be encountered
as noted in this manual. Choose a more suitable location if
necessary.
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.
Before using this manual, check the serial plate for proper
model identification.
The installation and servicing of this equipment must be
performed by qualified, experienced technicians only.

SHIPPING INSPECTION

Checking Product Received

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.

Message to the Homeowner

These instructions are addressed primarily to the installer;
however, useful maintenance information is included and
should be kept, after installation, for future reference.
