Step 3--Provide
Clearances
The required
minimum
service clearances
are shown
in Fig. 5 and
6. Adequate
ventilation
and outdoor
air nmst be provided.
The
outdoor
fan draws air through
the outdoor
coil and discharges
it
through
the top fan grille. Be sure that the fan discharge
does not
recirculate
to the outdoor
coil. Do not locate the unit in either a
corner or under
an overhead
obstruction.
The minimum
clearance
under a partial overhang
(such as a normal house overhang)
is 48 in.
above the unit top. The maximum
horizontal
extension
of a partial
overhang
must not exceed
48 in.
IMPORTANT:
Do not restrict outdoor airflow. An air restriction
at
either the outdoor-air
inlet or the fan discharge
may be detrimental
to compressor
life.
Do not place the unit where water, ice, or snow from an overhang
or roof will damage
or flood the unit. Do not install the unit on
carpeting
or other
combustible
materials.
Slab-mounted
units
should be at least 4 in. above the highest expected
water and runoff
levels. Do not use unit if it has been under water.

Rigging
and handling
of this equipment
can be hazardous
for many
reasons
clue to the installation
location (roofs.

2. Instruction
in any special operation
or precaution.
3. Condition
of the load as it relates to operation
of the lifting
kit, such as balance,
temperature,
etc.

intervals,
all rigging
brackets
and
straps should
be visually
inspected
for any damage,
evidence
of
wear. structural
defnrmation,
or cracks.
Particular
attention
should
be paid to excessive
wear at hoist hooking
points and load support
areas. Brackets
or straps showing
any kind of wear in these areas
must not be used and should be discarded.
