Section 8. Setting the Unit - Horizontal Installation

8.1 Considerations
Important: Due to the unique design of this unit,
which allows the electrical wiring to be routed within
the insulation, do not screw, cut, or otherwise puncture
the unit cabinet in any location other than the ones
illustrated in this Installer Guide or in an approved
accessory's Installer Guide.
Important: Make certain that the unit has been
installed in a level position to ensure proper draining.
Important: Under no conditions should metal
strapping be attached to the unit to be used as support
mechanisms for carrying or suspension purposes.
STEP 1 - Support the unit from the bottom (near both
ends). The service access must remain unobstructed.
Important: The unit can only be supported from the
bottom. Do not drill or screw supports into any area of
the cabinet.
Note: Do not allow the unit to be used as strain relief.
• Approved bottom support methods are rails,
u-channels (Unistrut®), or other load bearing
materials.
• The unit must be isolated carefully to prevent sound
transmission. Field supplied vibration isolators are
recommended.
STEP 2 - Install an auxiliary drain pan under the
horizontal air handler to prevent possible damage to
ceilings.
• Isolate the auxiliary drain pan from the unit and from
the structure.
• Connect the auxiliary drain pan to a separate drain
line and terminate according to local codes.
