• Carrying and installation of the unit should be performed by a suffi cient number
of people and with suffi cient equipment that is adequate for the weight of the unit.
Performing such work with an insuffi cient number of people or with inadequate equip-
ment could result in dropping of the unit or personal injury.
If the job is done with the panel frame only, there is a risk that the unit will come
loose. Please take care.
• When fastening the hangers, make the bolt positions uniform.

The air-handler must be adequately supported underneath if it is installed in the horizontal
position to prevent it from sagging in the middle which can cause issues removing and re-
installing the access panels. Position the unit on adequate supports or on support angles
or channels before connecting ductwork to the unit. If an auxiliary overfl ow pan is required
(See Section 3.4.5.), the overfl ow pan will need to be adequately supported with the air-
handler being supported underneath within the auxiliary overfl ow pan by angles and/or
channels.
Note:
Do not block air-handler access
with support rods,allow space for
proper service maintenance or
replacement of the coil and blower
assembly.
Supporting horiazontal air-handlers in auxiliary overfl ow pans or
air-handlers that are not suspended.
(Front side)
Base horizontal direction leveling on top of the unit.
3. 4. 5. Auxiliary overfl ow pan
In compliance with recognized codes, an auxiliary overfl ow pan must installed under all
equipment containing evaporator coils that are located in any area of a structure where
damage to the building or building contents may occur as a result of an overfl ow of the coil
drain pan or a stoppage in the primary condensate drain piping.
3. 4. 6. Clearances
• All units are designed for "0" inches clearance to combustible material on all cabinet
surfaces except for downfl ow application with higher kW electric heat as noted below.
• Units with electric heat require a one inch clearance to combustible material for the fi rst
three feet of supply plenum and ductwork.
• Vertical downfl ow applications require clearance on at least one side of the unit for
electrical connections. Refrigerant and condensate drain connections are made on the
front of the unit.
• All units require 24 in (610 mm) minimum access to the front of the unit for service.
• These units may be installed in either ventilated or nonventilated spaces.
