Installation of Unit

Installation of Unit

Inspection

1) Check for damage after unit is unloaded. Report promptly, to the carrier, any damage found to unit. Do not drop unit.
2) Check the unit nameplate to determine if the unit voltage is correct for the application. Determine if adequate
electrical power is available. Refer to the application specifications.
3) Check to be sure the refrigerant charge has been retained during shipment. Access to 1/4" flare pressure taps may
be gained by removing compressor compartment access panel.

Location and Recommendations

1) Unit Support
If unit is to be roof mounted check building codes for weight distribution requirements.
2) Location and Clearances
Installation of unit should conform to local building codes and the National Electrical Code.
Select a location that will permit unobstructed airflow into the condenser coil and away from the fan discharge and
permit unobstructed service access into the compressor compartment. Suggested airflow clearances and service
clearances are given in Figure 1.
3) Placing and Rigging
Rig the unit using either belt or cable slings. The sling eyelet must be placed through the lifting holes in the base rail
of the unit. The point where the slings meet the lifting eyelet should be at least 6 feet above the unit. Use spreader
bars to prevent excessive pressure on the top of the unit during lifting.
: The use of "spreader bars" is required when hoisting the unit (prevents damage to sides and top). Top
NOTICE
crating can be used as spreader bars.
4) Roof Mounted Units
On new roofs, the curb should be welded directly to the roof deck. For existing construction, nailers must be installed
under the curb if welding is not possible. Be sure attach the downflow ductwork to the curb before setting unit in
place.
When installing the unit, it must be level to insure proper condensate flow from the unit drain pan.
