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, scratched or dented panels
should be reported to carrier immediately. An internal
inspection of each unit should be performed prior to
installation. Remove all access doors and check for
visual defects that can occur during transport. Any prob-
lems found internally should be reported to carrier and
manufacturer immediately. Refrigerant circuit should be
checked to ensure no leaks have occurred during ship-
ment. Install gauge set on 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.
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
Prior to mounting unit, check individual
unit weights (pages 7-8) and verify lifting
capacity of lifting equipment exceeds
weight of units by safe margins. Failure
to do so may result in unit damage, per-
sonal 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 com
-
ponents for each unit is different and weight is unevenly
distributed.
Determine the actual center of gravity of
the unit by performing a test lift. Lifting
an unbalanced unit can cause personal
injury or even death.
INSTALLATION
Lock all electrical power supply switch-
es in the off position before installing
the unit. Failure to disconnect power
supply may result in electrical shock or
even death.
Location - To ensure unit operates at maximum efficien
-
cies, choose a dry indoor area where the temperature
is controlled between 50 deg F and 115 deg F. Con-
sideration 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 equipment.
Failure to allow adequate space between
units may result in poor unit perfor-
mance and possible unit failure.
Refer to typical installation diagram (Page #5).
Install thermostats, air supplies and returns so that each
unit will operate only on individual unit control. To assure
fast drainage of condensate run-off, unit can be slightly
pitched in the same direction as drain pan outlet.
