Pre-Installation
The final position for the air handler must be dictated
by required service access to it, weight distribution
over structural supports, and by the locations of
electrical, refrigerant and condensate drainage
connections. After this is determined, the following
preparations should be made.
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 TWE 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. 21 for
approximate unit weights.
The crated unit can be moved using a forklift of suitable
capacity. For lifting the unit into an elevated mounting
position, run lifting straps or slings under the unit and
attach securely to the lifting device.
Repositioning Drain Pan
Air handlers come with one drain pan that can be
installed in any one of four positions; this allows for
vertical or horizontal application and right or left
condensate line connection.
N No otte e:: Important! All air handlers are shipped with the
drain pan installed in the horizontal position and
the connection on the left side (as shown in
Figure 1, p. 8 . If an alternate position is required,
the drain pan should be repositioned before
setting the air handler. Ensure there is enough
clearance to the sides of the unit for
repositioning the drain pan after installation.
1. Remove the access plate at the opposite end of the
drain connection. This plate secures and lifts the
back end of the drain pan for sloping. It must be
removed before the drain pan can be removed. This
