Handler Upside Down as shown in the above figure.
Horizontal Installations
Horizontal installations can be left-hand or right-hand air
supplied. Adequate support must be provided to ensure cabinet
integrity. Ensure that there is adequate room to remove service
and access panels if installing in the horizontal position. Refer
to instructions provided with coil for proper horizontal
installations.

IMPORTANT:
•
Refer to the instructions provided with the coil being
used to determine how the secondary drain should be
trapped and piped.
•
When an evaporator coil is installed in an attic or
above a finished ceiling, an auxiliary drain pan should
be provided under the MX Series Air Handler and coil
as specified by most local building codes.
Conversion from Vertical to Horizontal
The MX Series Air Handler can be converted from operating in a
vertical to a horizontal position by installing supporting brackets
(included with all MX Series Air Handlers) between the two
pieces of equipment. A horizontal condensate drain pan (not
included with the MX Series Air Handler) would also be needed.
Suspended Cabinet Installation
NOTE:
MX Series Air Handlers cannot be installed horizontally
lying on or suspended from either the front or back of the MX
Series Air Handler. If installed horizontally the blower must be
positioned with one side parallel to the floor.
The suspending means must be field fabricated, and should
consist of 2 “cradles” made by attaching 2 rods to a length of
angle iron or suitable gauge steel.
