Pre-Installation
Unit Inspection
Inspect material carefully for any shipping damage. If
damaged, it must be reported to, and claims made
against the transportation company. Compare the
information that appears on the unit nameplate with
ordering and submittal data to ensure the proper unit
was shipped. Available power supply must be
compatible with electrical characteristics specified on
component nameplates. Replace damaged parts with
authorized parts only.
IIm mp po orrtta an ntt:: Units ordered with a VFD cannot be field
converted to 460 V from 208-230 or from
208-230 V to 460 V.
Inspection Checklist
To protect against loss due to damage incurred in
transit, complete the following checklist upon receipt of
the unit.
☐ Inspect individual pieces of the shipment before
accepting the unit. Check for obvious damage to the
unit or packing material.
☐ Inspect the unit for concealed damage before it is
stored and as soon as possible after delivery.
Concealed damage must be reported within 15
days. If concealed damage is discovered, stop
unpacking the shipment. Do not remove damaged
material from the receiving location. Take photos of
the damage if possible. The owner must provide
reasonable evidence that the damage did not occur
after delivery.
☐ Notify the carrier’s terminal of damage immediately
by phone and by mail. Request an immediate joint
inspection of the damage by the carrier and the
consignee.
☐ Notify the sales representative and arrange for
repair. Do not repair the unit until the damage is
inspected by the carrier’s representative.
Testing for Leaks
All units are shipped with a holding charge of nitrogen
in each circuit and should be leak tested before
installation.
1. Remove the access panel.
2. Locate the liquid line or suction line access valve for
each circuit.
3. Install gauges to determine if the circuits are still
pressurized. If not, the charge has escaped and
should be repaired as required to obtain a leak-free
circuit.

Before preparing the unit for lifting, estimate the
approximate center of gravity for lifting safety. Because
of placement of internal components, the unit weight
may be unevenly distributed. See
“Weights,” p. 16 for
approximate unit weights.
The crated unit can be moved using a forklift of suitable
capacity. For lifting the unit, attach lifting straps or
slings securely to the lifting holes at each corner (see
unit drawings in
“Weights,” p. 16 ). Use spreader bars
to protect the unit casing from damage. Test lift the
unit to determine proper balance and stability.
Clearances
Provide enough space around the unit to allow
unrestricted access to all service points. Refer to the
“Dimensional Data,” p. 10 for unit dimensions and
minimum required service and free air clearances.
Observe the following points to ensure proper unit
operation.
1. Do not install the unit under a low overhang.
Condenser discharge must not be restricted—refer
to notes in
“Dimensional Data drawings,” p. 10 .
IIm mp po orrtta an ntt:: Do not obstruct condenser discharge
air. This can result in warm air
recirculation through the coil.
2. Do not locate the unit in a position where runoff
water, or falling snow from roof, can fall into the fan
discharge openings.
3. Condenser intake air is supplied from three or four
sides of the unit. Adhere to the minimum required
clearances given in unit dimensional drawings (see
