PRE-INSTALLATION INSPECTION OF
EQUIPMENT
All units are factory tested to ensure safe operation and
quality assembly. Units are packaged and sealed on
wooden skid runners and shipped in first class condi-
tion. Torn and broken packaging, scratched or dented
panels should be reported to carrier immediately. Inter-
nal 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 pres-
sure ports to confirm pressure has been maintained
and no leaks have occurred during shipment. Repair
any damage prior to installation to ensure safe opera-
tion.
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
INSTALLATION
Location
- To ensure unit operates at maximum effi-
ciencies, choose a dry indoor area where the tempera-
ture is controlled between 40° F and 115° F.
Consideration of surrounding areas should be taken
when choosing a location to install the unit. Common
vibration and sound levels associated with commercial
equipment may be objectionable to people or equip-
ment.
Install thermostats, supply air ductwork, and return air
ductwork (if applicable) so that each unit will operate
only in a single cooling or heating zone. In order to
assure proper drainage of condensate, horizontal units
can be slightly pitched in the same direction as drain
pan outlet.
Prior to mounting unit, check individual unit
weights (page 4) and verify lifting capacity of lifting
equipment exceeds weight of units by safe mar-
gins. failure to do so may result in unit damage,
personal injury or even death.
Lock all electrical power supply switches in the
off position before installing the unit. Failure to
disconnect power supply may result in electrical
shock or even death.
Only qualified personnel should perform installa-
tion and service of this equipment.
Failure to allow adequate space between units
may result in poor unit performance and possible
unit failure.
