INSTALLATION
I. COMPLETE
A. Uncrate Unit
Remove unit packaging except for the top skid assembly, which should be left in place until after the unit is rigged into its final location.
B. Inspect Shipment
File claim with shipping company if shipment is damaged or incomplete.
C. Consider System Requirements
•Consult local building codes and National Electrical Code (NEC) for special installation requirements.
•Allow sufficient space for airflow clearance, wiring, refrig- erant piping, and servicing unit. See Fig.
•Locate unit so that outdoor coil airflow is unrestricted on all sides and above.
•Unit may be mounted on a level pad directly on the base channels or mounted on raised pads at support points. See Table 1 for unit operating weights.
II.RIG AND MOUNT UNIT
CAUTION: Be sure unit panels are securely in place prior to rigging. Be careful rigging, handling, and installing unit. Improper unit location can cause sys- tem malfunction and material damage. Inspect base rails for any shipping damage and make sure they are fastened securely to unit before rigging.
A. Rigging
These units are designed for overhead rigging. Refer to rig- ging label for preferred rigging method. Spreader bars are not required if top crating is left on unit. All panels must be in place when rigging. As further protection for coil faces, plywood sheets may be placed against sides of unit, behind cables. Run cables to a central suspension point so that angle from the horizontal is not less than 45 degrees. Raise and set unit down carefully.
If it is necessary to roll the unit into position, mount the unit on
Raise from above to lift unit from the rails or pad when unit is in final position.
After unit in position, remove all shipping materials and top crating.
