CAUTION
Only qualified personnel should perform installation and service of this equipment.
Pre-installation inspection of equipment
All units are factory tested to ensure safe operation and quality assembly. Units are packaged
and sealed on shipping skids and shipped in first class condition. Torn and broken packaging
and scratched or dented panels should be reported to carrier immediately. Internal inspection of
all units should be performed prior to installation. Remove all access doors and check for visual
defects that can occur during transport. Any problems found internally should be reported to
carrier and manufacturer immediately. Refrigerant circuit should be checked to ensure no leaks
have occurred during shipment. Install gauge set to high and low pressure ports to confirm
pressure has been maintained and no leaks have occurred during shipment. Repair any damage
prior to installation to ensure safe operation.
Note:
Record any unit damage on the Bill of Lading and report to carrier and factory
immediately. Shipping and handling damages are not warranty items.
Rigging
WARNING
Prior to mounting unit, check individual unit weights (Table 1) and verify lifting capacity of lifting
equipment exceeds weight of units by safe margins. Failure to do so may result in unit damage,
personal injury, or even death.
To ensure safe installation of the unit when ceiling mount application is specified, estimate the
approximate center of gravity of the unit. The configuration of internal components for each unit is
different and weight is unevenly distributed.
