General Mounting

Securely attach the outdoor unit to a condenser pad, base rails, or

another mounting platform that is securely anchored to the ground or

building structure. Attach the outdoor unit with a bolt and nut on a con-

crete or rigid mount. See Figure 3. Follow applicable local codes for

clearance, mounting, anchor and vibration attenuation requirements.

All referenced materials are to be eld-supplied. Images are not to scale.

Mounting Platform

The underlying structure or foundation must be designed to support

the weight of the unit. Avoid placing the unit in a low lying area

where water may accumulate. When installing the outdoor unit on

the wall or roof top, anchor the mounting base securely to account

for wind, earthquakes or vibration.

Tie-Downs and Wind Restraints

The strength of the Single Zone system frame is adequate to

be used with field-provided wind restraint tie-downs. The overall

tie-down configuration must be approved by a local professional

engineer.

Always refer to local code when designing a wind restraint system.

Snow and Ice Conditions

In climates that experience snow build-up, place the unit on a raised platform to ensure condenser airflow. The raised support platform must

be high enough to allow the unit to remain above possible snow drifts. Mount the unit on a field-provided snow stand at a minimum height

that is equal to the average annual snowfall plus 20 inches. Design the mounting base to prevent snow accumulation on the platform in front

or back of the unit case. If necessary, provide a field fabricated hood to keep snow and ice and/or drifting snow from accumulating on the coil

surfaces. Use inlet and discharge duct or hoods to prevent snow or rain from accumulating on the fan inlet and outlet guards. Best practice

prevents snow from accumulating on top of the unit. Consider tie-down requirements in case of high winds or where required by local codes.

When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on

sidewalks or driveways which may create unsafe conditions.

Proper airflow through the Single Zone outdoor unit coil is critical for correct unit operation. When installing, consider service, inlet and outlet,

and minimum allowable space requirements as illustrated in the diagrams to follow.

Minimum Clearance Requirements for Single Zone Systems

Outdoor Unit Clearance

Specific clearance requirements in the diagrams on the next page are for the single zone wall mount systems. Figure 4 shows the overall

minimum clearances that must be observed for safe operation and adequate airflow around the outdoor unit.

When placing the outdoor unit under an overhang, awning, sunroof or other "roof-like structure, observe the clearance requirements (as shown

in Figure 5) for height in relation to the unit. This clearance ensures that heat radiation from the condenser is not restricted around the unit. See

Figures 6 and 7 for recommendations when other obstacles are present.

Adhere to all clearance requirements if installing the unit on a roof. Be sure to level the unit and ensure that the unit is adequately anchored.

Consult local codes for rooftop mounting requirements.
