SECTION 6: LIFTING AN AIR HANDLER
WARNING
Crush Hazard
Use proper lifting equipment and practices.
Failure to follow these instructions can result
in death, injury or property damage.
The air handler must be installed in compliance with
all applicable codes. The qualified installer or service
technician must use best building practices when
installing the air handler and any optional equipment.
This piece of equipment requires at least 4 CFM (6.8
3
m
/
) of outside air per 1,000 Btu/h (0.293 kW). Any
h
air handler that recirculates air from the heated
space must use the return air opening to prevent any
return air from passing over the burner.
Before installation, check that the local distribution
condition, nature of gas and gas pressure, and the
current state of adjustment of the equipment are
compatible. If filters are not installed (via inlet hood or
filter section), an air strainer (provided by others)
must be installed on the inlet of the air handler with
openings less than or equal to 5/8" (16 mm) in
diameter. Air inlets must be installed in such a
manner that their lowest edge is 19" (500 mm) above
any surface. This applies to roof curbs, upright
stands and suspended air handlers.
6.1 Lifting an Air Handler
6.1.1 Preparing to Lift the Air Handler
Prior to lifting the air handler, the following steps must
be performed:
1.
Remove all packaging or banding that attached
the air handler to the skid and ensure that the
air handler is no longer bound to the skid.
2. Remove all of the accessories or packages that
were shipped on the same skid, inside the air
handler or inside the control enclosure.
3. Inspect the air handler to:
•
Verify that there is no damage as a result of
shipping.
•
Ensure that it is appropriately rated for the
utilities available at the installation site.

•
Verify that the lifting lugs are intact
undamaged and secured to the air handler.
•
Ensure factory-installed hardware is
torqued as specified.
4. Prepare the installation location to be ready to
accept the air handler (i.e. roof curb, mounting
stand or legs).
5. Verify the lifting equipment can handle the air
handlers weight and the required reach. See
Page 8, Table 2.
6.1.2 Lifting a Horizontal Air Handler (All Models)
Lift the air handler into place installing appropriate
hardware (supplied by others) into all lifting lug holes
on the unit base. For model XT-112, lifting lug holes
are 1.5" (3.81 cm) diameter. For models XT-115 - XT-
130, lifting lug holes are 2.0" (5.1 cm) diameter. Use
spreader bars to ensure that the lifting cables clear
the sides of the air handler. The air handler must be
kept level during the lift to prevent tipping, twisting or
falling. If lifted improperly, product damage may
occur.
Next, refer to the applicable portions of Section 7,
See Pages 12 - 14 for specific mounting instructions.
For mounting of accessories, refer to the applicable
portions of Page 21, Section 10.1 through Page 32,
Section 13.
