SECTION 6: LIFTING AN AIR HANDLER
The air handler m u st be installed in compliance w ith
all applicable codes. The q u alified installer or ser v ice
technician m u st u se best b u ilding practices w hen
installing the air handler and any optional eq u ipment.
This piece of eq u ipment req u ires at least 4 CFM (6.8
m
3
/
h
) of o u tside air per 1,000 Bt u /h (0.293 kW). Any
air handler that recirc u lates air from the heated
space m u st u se the ret u rn air opening to pre v ent any
ret u rn air from passing o v er the b u rner.
Before installation, check that the local distrib u tion
condition, nat u re of gas and gas press u re, and the
c u rrent state of adj u stment of the eq u ipment are
compatible. If filters are not installed ( v ia inlet hood or
filter section), an air strainer (pro v ided by others)
m u st be installed on the inlet of the air handler w ith
openings less than or eq u al to 5/8" (16 mm) in
diameter. Air inlets m u st be installed in s u ch a
manner that their lo w est edge is 19" (500 mm) abo v e
any s u rface. This applies to roof c u rbs, u pright
stands and s u spended air handlers.

6.1.1 Preparin g to Lift the Air Handler
Prior to lifting the air handler, the follo w ing steps m u st
be performed:
1. Remo v e all packaging or banding that attached
the air handler to the skid and ens u re that the
air handler is no longer bo u nd to the skid.
2. Remo v e all of the accessories or packages that
w ere shipped on the same skid, inside the air
handler or inside the control enclos u re.
3. Inspect the air handler to:
• Verify that there is no damage as a res u lt of
shipping.
• Ens u re that it is appropriately rated for the
u tilities a v ailable at the installation site.
• Verify that the lifting l u gs are intact
u ndamaged and sec u red to the air handler.
• Ens u re factory-installed hard w are is
torq u ed as specified.
4. Prepare the installation location to be ready to
accept the air handler (i.e. roof c
u rb, mo u nting
stand or legs).
5. Verify the lifting eq u ipment can handle the air
handlers w eight and the req u ired reach. See
Page 17, Figure 9 . For air handlers w eight, see
Page 12, Table 3 and Page 12, Table 4 for
model 2005. See Page 14, Table 6 and Page

6.1.2 Liftin g a Horizontal Air Handler (All Models)
Lift the air handler into place installing appropriate
hard
w are (s u pplied by others) into all lifting l u g holes
on the u nit base. For model 2005, lifting l u g holes are
1.5" (3.81 cm) diameter. For models 2010 - 2030,
lifting l
u g holes are 2.0" (5.1 cm) diameter. Use
spreader bars to ens u re that the lifting cables clear
the sides of the air handler. The air handler m u st be
kept le v el d u ring the lift to pre v ent tipping, t w isting or
falling. If lifted improperly, prod u ct damage may
occ u r.
