AIRFLOW ADJUSTMENT
If the airflow needs to be increased or decreased, see
the Airflow Label on the air handler or the Blower Per-
formance table in these Service Facts. Information on
changing the speed of the blower motor for your specific
outdoor model size is in the Blower Performance Table
or User Interface Menu.
Blower speed changes are made with the User Interface
Menu mounted in the control box.

CAUTION
!
RECONNECT ALL GROUNDING DEVICES.
All parts of this product that are capable of conducting
electrical current are grounded. If grounding wires,
screws, straps, clips, nuts, or washers used to com-
plete a path to ground are removed for service, they
must be returned to their original position and prop-
erly fastened.
HAZARDOUS VOLTAGE - DISCONNECT POWER BEFORE SERVICING
WARNING:
IMPORTANT — This document contains a wiring diagram
and service information. This is customer property and is
to remain with this unit. Please return to service information
pack upon completion of work.

WARNING
!
THIS INFORMATION IS INTENDED FOR USE BY INDI-
VIDUALS POSSESSING ADEQUATE BACKGROUNDS
OF ELECTRICAL AND MECHANICAL EXPERIENCE.
ANY ATTEMPT TO REPAIR A CENTRAL AIR CONDI-
TIONING PRODUCT MAY RESULT IN PERSONAL IN-
JURY AND OR PROPERTY DAMAGE. The manufacturer
or seller cannot be responsible for the interpretation of
this information, nor can it assume any liability in con-
nection with its use.
1These Air Handlers are A.R.I. certified with various Split System Air Condi-
tioners and Heat Pumps (ARI STANDARD 210/240). Refer to the Split Sys-
tem Outdoor Unit Product Data Guides for performance data.
23/4" Male Plastic Pipe (Ref.: ASTM 1785-76)
3Minimum filter size for horizontal applications will be based on airflow selec-
tion and will be calculated as follows:
Low Velocity Filter: Face area (Sq. Ft.) = CFM / 300
High Velocity Filter: Face area (Sq. Ft.) = CFM / 500
4 Torque Spec for TXV = Tighten 1/6 turn past finger tight
5 See Installer's Guide for drawings
6 For customer ease of filter maintenance, it is recommended that a properly
sized, remote filter and grille be installed for horizontal applications. Airflow
should not exceed the face value of the filter being used. The factory in-
stalled filter should then be removed from the unit.

NOTES:
Airflow Demand is OD size (tons) * Speed (cfm/ton)
COMM SYS mode will auto-detect OD size, with default speed 400cfm/ton & 1.5 minute off-delay
At continuous fan setting: Airflow values are approximately 50% of listed values.

UNIT TEST MODE
Unit Test Mode (Air Handler)
The system must be idle or thermostat switched to
“OFF” before the Unit Test will run the air handler. The
unit will work the same way in either the Communicating
Mode or 24 volt AC mode.
To access the Unit Test Mode scroll down through the
User Interface Information Menu until you see the Unit
Test option. Press ENTER. When prompted select YES
and press ENTER. When the User Interface displays
ARE YOU SURE? select YES and press ENTER to begin
the Unit Test.
NOTE: While in Test Mode all thermostat requests will
be ignored but if any button on the User Interface is
pressed, the Unit Test will exit. The Unit Test will exit
if a fault is detected during the test sequence.
The Unit Test will perform the following steps without
delays.
1. Start blower at 50% airflow and Energize EAC relay.
2. After 10 seconds, go to 100% airflow for 10 seconds.
(User Interface displays UNIT TEST – BLWR)
3. Energize Y1 relay for 15 seconds with 100% airflow.
(User Interface displays UNIT TEST – COOL)
4. De-energize Y1 relay and go to Electric Heat airflow.
(User Interface displays UNIT TEST – HEAT)
5. Energize blower interlock and stage 1 heat relay.
6. Energize humidifier relay.
7. After 1 second energize stage 2 heat relay.
8. After 1 more second energize stage 3 heat relay.
9. After 5 seconds de-energize blower interlock, stage
1, 2 & 3 heat, humidifier and EAC relays.
(User Interface displays UNIT TEST – EXIT)
Displayed for three seconds
NOTE: Airflow is default or programmed selections.
