RETURN- - AIR FILTERS (in.)†
Throwaway
*Based on altitude of 0 to 2000 ft.
{Recommended filter sizes for field- -installed air filter grilles mounted on the wall or ceiling of the conditioned structure. Required filter sizes shown are based on the larger of the
ARI (Air Conditioning and Refrigeration Institute) rated cooling airflow or the heating airflow velocity of 300 ft/minute for throwaway type or 450 ft/minute for high- -capacity
type. Air filter pressure drop for non- -standard filters must not exceed 0.08 in. wg.
Step 3—Provide Clearances
The required minimum service clearances are shown in Fig. 5 and
6. Adequate ventilation and outdoor air must 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.

Step 4—Rig and Place Unit
Rigging and handling of this equipment can be hazardous for many
reasons due to the installation location (roofs, elevated structures,
etc.).
Only trained, qualified crane operators and ground support staff
should handle and install this equipment.
When working with this equipment, observe precautions in the
literature, on tags, stickers, and labels attached to the equipment, and
any other safety precautions that might apply.
Training for operators of the lifting equipment should include, but
not be limited to, the following:
1. Application of the lifter to the load, and adjustment of the
lifts to adapt to various sizes or kinds of loads.
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.
Follow all applicable safety codes. Wear safety shoes and work
gloves.
