If conditions or local codes require the unit be attached to 

pad or mounting frame, tie down bolts should be used and 

secured to unit base pan.

Structure

Mounting slab must slope slightly away from 

building, not to exceed 1/4” per foot.

Elevate Unit

Accumulation of water and ice in base pan may cause 

equipment damage.

 CAUTION

Elevate  unit  per  local  climate  and  code  requirements  to 

provide  clearance  above  estimated  snowfall  level  and 

ensure adequate drainage of unit. Use snow stand in areas 

where prolonged freezing temperatures are encountered.

If conditions or local codes require the unit be attached to 

pad or mounting frame, tie down bolts should be used and 

fastened through knockouts provided in unit base pan.

Clearance Requirements

When installing, allow sufficient space for airflow clearance, 

wiring, refrigerant piping, and service. For proper airflow, 

quiet operation and maximum efficiency. Position so water, 

snow, or ice from roof or eaves cannot fall directly on unit. 

Refer to Table 2 for installation clearances.

NOTE: See Table 2 for specific minimum clearance guidelines.

DO LOCATE THE UNIT:

• 

With proper clearances on sides and top of unit

• 

On a solid, level foundation or pad (unit must be level 

to  within  ±  1/4  in./ft.  per  compressor  manufacturer 

specifications)

• 

To minimize refrigerant line lengths

DO NOT LOCATE THE UNIT:

• 

On brick, concrete blocks or unstable surfaces

• 

Near  clothes  dryer  exhaust  vents  where  debris 

accumulates

• 

Near sleeping area or near windows

• 

Under eaves where water, snow or ice can fall directly 

on the unit 

• 

With clearance less than 2 ft. from a second unit

• 

With clearance less than 4 ft. on top of unit

Operating Ambient

The minimum outdoor operating ambient in cooling mode 

is  55°F,  and  the  maximum  outdoor  operating  ambient  in 

cooling mode is 125°F. The maximum outdoor operating 

ambient in heating mode is 66°F.

Rooftop Installations

Install unit at a minimum of 6” above surface of the roof 

to  avoid  ice  buildup  around  the  unit.  Locate  the  unit 

above  a  load  bearing  wall  or  area  of  the  roof  that  can 

adequately support the unit. Consult local codes for rooftop 

applications.

If unit cannot be mounted away from prevailing winds, a 

wind  barrier  should  be  constructed.  Due  to  variation  in 

installation applications, size and locate barrier according 

to the best judgment of the installer.
