UNIT CLEARANCES
*In situations that have multiple units, a 48” minimum clearance is
required between the condenser coils.
Adequate clearance around the unit should be kept for safety,
service, maintenance, and proper unit operation. A total
clearance of 75” on the main control panel side of the unit is
recommended to facilitate possible fan shaft, coil, and electric
heat. A clearance of 48” is recommended on all other sides
of the unit to facilitate possible compressor removal, to allow
service access and to insure proper ventilation and condenser
airflow. The unit must not be installed beneath any obstruction.
The unit should be installed remote from all building exhausts
to inhibit ingestion of exhaust air into the unit fresh air intake.

ROOF CURB INSTALLATION
ROOF CURB POST-INSTALLATION CHECKS
After installation, check the top of the curb, duct connection
frame and duct flanges to make sure gasket has been applied
properly. Gasket should be firmly applied to the top of the curb
perimeter, duct flanges and any exposed duct connection
frame. If gasket is loose, re-apply using strong weather
resistant adhesive.
Protrusion
Inspect curb to ensure that none of the utility services (electric)
routed through the curb protrude above the curb.
CAUTION
If protrusions exist, do not attempt to set unit on curb.
ROOF TOP DUCT CONNECTIONS
Install all duct connections on the unit before placing the
unit on rooftop.
Horizontal Discharge
Refer to IOD-7006 included in the literature pack for installing
horizontal duct covers.
Flexible duct connectors between the unit and ducts are
recommended. Insulate and weatherproof all external ductwork
and joints as required and in accordance with local codes.
HORIZONTAL DISCHARGE DUCT CONNECTIONS
RIGGING DETAILS
WARNING
To prevent property damage, the unit should remain in an
upright position during all rigging and moving operations.
To facilitate lifting and moving when a crane is used,
place the unit in an adeequate cable sling.
WARNING
If units are lifted two at a time, the fork holes on the
condenser end of the unit must not be used. Minimum fork
length is 42” to prevent damage to the unit; however, 48”
is recommended.
Provisions for forks have been included in the unit base frame.
No other fork locations are approved.
WARNING
To prevent possible equipment damage, property damage,
personal injury or death, the following bullet points
must be observed when installing the unit.
