2. Remove the "J" shaped bracket that retains the
evaporator coil.
3. Remove the flowrater from the lower left side access
panel and slide out the evaporator coil and horizontal
drain pan.
4. Remove the gasket from the horizontal pan drain
connections.
5. Remove the oval shaped plastic plug from the left side
access panel. Remove the oval shaped rubber gasket
seal from the lower right side access panel.
6. The drain connections for the horizontal pan are sealed
with a thin coating of plastic. Carefully knock out this
plastic seal with a screwdriver and hammer. Note: The
upper drain will become the secondary drain
which is mandatory in many municipalities .
7. Install the plastic plug removed in step 5 to the right
side lower access panel and the oval shaped rubber
gasket to the lower left access panel.
8. Reinstall the evaporator coil with the horizontal panel
on the left side. Note: Push the assembly completely
to the rear to ensure the engagement of the upflow pan
with the rear channel bracket.
9. Install the "J" bracket (removed in step 2) to support the
upflow pan to the tie channel.
10. Attach all panels and the metering device.

CONDENSATE REMOVAL

The drain pan has a primary and secondary drain connection
(Figure 8). Condensate removal is performed by attaching
a ¾" PVC pipe to the evaporator coil pan and terminated in
accordance with local or state Plumbing/HVAC codes. The
installation must include a "P" style trap that is located as
close as is practical to the evaporator coil. Exercise caution
not to over-tighten the drain connection(s) in order to prevent
possible damage to the evaporator drain pan. See Figure
8 for details of a typical condensate line "P" trap.
Installations that are above a finished ceiling may require a
field supplied auxiliary drain pan. Consult local codes on
this requirement.

AT TRAP
Use of a condensate removal pump is permitted when
necessary. This condensate pump should have provisions
for shutting off the control voltage should a blocked drain
occur. A trap must be installed between the unit and the
condensate pump.
IMPORTANT NOTE: THE EVAPORATOR COIL IS COATED
WITH OILS THAT MAY DISSOLVE STYROFOAM AND
CERTAIN TYPES OF PLASTICS. THEREFORE, A
REMOVAL PUMP OR FLOAT SWITCH MUST NOT
CONTAIN ANY OF THESE MATERIALS.
Tip: Priming the "P" trap may avoid improper draining at the
initial installation and at the beginning of the cooling season.

ACHIEVING 2% LOW LEAKAGE RATE

Ensure that the Neoprene gasket with PSA remains intact
on all surfaces that the access panels are secured to. These
surfaces are the entire length of the wrapper and areas
between the upper tie plate, upper and lower access panels.
Be sure that upper access panel breaker insert gasket is
intact and also flowrator gasket is installed on the lower
access panel. An additional drain hole cover is required.

ARUF/ARPF/ADPF MOTOR

Motor Speed Adjustment
The motors in all ARUF, ARPF and ADPF motors are multi-
speed PSC motors. The color of the wire coming from the
motor to the "COM" terminal on the control board defines in
which speed the motor will operate. The black wire
represents high speed, the red wire represents low speed,
and the blue wire (select models only) represents medium
speed. To change speeds, remove the wire attached to the
"COM" terminal on the control board, and swap it with the
wire (on terminal "M1" or "M2") with the color that will give
the desired speed.
NOTE: In some models, not all speed taps are allowable
for certain electric heat applications. Refer to air handler
Series and Ratings plate for minimum speed.

AEPF MOTOR

This section references the operation characteristics of the
AEPF model motor only. The ECM control board is factory
set with dipswitch #4 in the "ON" position and all other
dipswitches in the "OFF" position. For most applications
this setting is to be changed according to the electric
heat size and the outdoor unit selection.
