Outdoor Installation

general Mounting
Securely attach the outdoor unit to a condenser pad,
base rails, or other mounting platform that is securely
anchored to the ground or building structure. Attach the
oDU with a bolt and nut onto a concrete or rigid mount
(Figure 9). Refer to installation manual and follow the
applicable local code for clearance, mounting, anchor,
and vibration attenuation requirements.
All referenced materials are to be field-supplied.

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 oDU on the wall, or roof top, anchor the mounting base securely using nails or wire with regard to
wind and earthquake or vibration.
tie-downs and Wind restraints
The strength of the Single Zone Art Cool Premier 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 buildup, place the unit on a raised platform to ensure proper 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.
ambient air Conditions
Avoid exposing the outdoor unit to steam, combustible gases, or other corrosive elements. Avoid exposing the unit to discharge from boiler
stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumbing vents, and other sources of extreme
temperature, gases, or substances that may degrade performance or cause damage to the unit.
When installing multiple outdoor units, avoid placing the units where discharge of one outdoor unit will blow into the inlet side of an adjacent unit.
