When removing the coil, there is possible danger of

equipment damage and personal injury. Be careful

when removing the coil assembly from a unit installed

in right- or left-hand applications. The coil may tip into

the drain pan once it is clear of the cabinet. Support the

coil when removing it.

Horizontal Left-Hand Discharge Application

NOTE: For horizontal applications, a secondary drain pan

is recommended. Refer to local codes.

After removal of drain pan plug(s), check drain hole(s)

to verify that drain opening is fully open and free of any

debris. Also check to make sure that no debris has

fallen into the drain pan during installation that may plug

up the drain opening.

Rotate drain pan 180º front-to-back and install it on the

opposite side of the coil.

Remove screws from top cap. Remove horizontal drip

shield screw located in the center of the back coil end

seal as illustrated in Figure 4.

Rotate horizontal drip shield 180º front-to-back.

Remove plastic plug from left hole on coil front end seal

and reinstall plug in back hole. Reinstall horizontal drip

shield screw in front coil end seal. Drip shield should

drain downward into horizontal drain pan inside coil.

DOWN-FLOW RAIL

Figure 5. Left-Hand Discharge Configuration

Rotate top cap 180º front-to-back and align with

unused screw holes. Holes must align with front and

back coil end plates. The top cap has a 45º bend on

one side and a 90º bend on the other. The 90º bend

must be on the same side as the horizontal drain pan

as illustrated in Figure 4.

NOTE: Be very careful when reinstalling the screws

into the coil end plate engaging holes. Misaligned

screws may damage the coil.

From the upflow position, flip cabinet 90º to the left

and set into place. Replace blower assembly. Secure

coil in place by bending down the tab on the cabinet

support rail as illustrated in Figure 4 and Figure 5.

10. Install the horizontal shield (-060 model only) on the

front edge of the horizontal drain pan as illustrated in

Figure 5.

NOTE: For horizontal applications in high humidity

areas, remove the downflow rail closest to the drain

pan. To remove rail, remove screw from rail at back

of unit and at cabinet support rail. Remove downflow

rail then replace screws. Also, seal around the exiting

drain pipe, liquid and suction lines to prevent infiltration

of humid air.
