For ease in installation, it is best to make any necessary coil

configuration changes before setting the air handler in place. See

"Installation Configuration Options."

Upflow air discharge contains only 1 drain pan.

Upflow or horizontal airflow contains 2 drain pans.

Vertical Installations

Upflow

The air handler must be supported on the bottom only and set on

a field-supplied supporting frame with an air return opening.

Securely attach the air handler to the supporting frame.

Horizontal Installations

Horizontal installations can be left-hand or right-hand air supply.

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. For the

correct horizontal coil installation, see "Installation Configuration

Options" later in this section.

IMPORTANT:

This coil is provided with a secondary drain that should be

trapped and piped to a location that will give the occupant a

visual warning that the primary drain is clogged. See "Install

Condensate Drain."

When an evaporator coil is installed in an attic or above a

finished ceiling, an auxiliary drain pan should be provided

under the air handler as specified by most local building

codes.

Suspended Cabinet Installation

NOTE: Air handlers cannot be installed horizontally lying on or

suspended from either the front or back of the air handler. It must

be positioned with one side parallel to the floor when in the

horizontal position.

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.
