INSTALLATION
INSPECTION
Immediately upon receiving the unit, it should be in-
spected for possible damage which may have occurred
during transit. If damage is evident, it should be noted
in the carrier’s freight bill. A written request for inspec-
tion by the carrier’s agent should be made at once. See
“Instruction” manual, Form 50.15-NM for more infor-
mation and details.
LOCATION AND CLEARANCES
These units are designed for outdoor installations on
ground level, rooftop, or beside a building. Location
should be selected for minimum sun exposure and to
insure adequate supply of fresh air for the condenser.
The units must be installed with sufficient clearances
for air entrance to the condenser coil, for air discharge
away from the condenser, and for servicing access.
In installations where winter operation is intended and
snow accumulations are expected, additional height
must be provided to insure normal condenser air flow.
Clearances are listed under “Notes” in the “DIMEN-
SIONS” section.
The unit should be lifted by inserting hooks through
the holes provided in unit base rails. Spreader bars
should be used to avoid crushing the unit frame
rails with the lifting chains. See below.
