For Canadian installations the electrical connections
and grounding shall comply with the current Canadian
Electrical Code (CSA C22.1 and/or local codes).
Every effort should be made by the installer to ensure
thatthefieldinstalledrefrigerantcontainingcomponents
of the system have been installed in accordance with

label to determine the correct amount of charge.
Refrigerant charging charts are applicable only to
matched assemblies of this equipment and listed
airflows for the indoor coil. Refer to Figures 4 - 10
(Pages 9 - 12) for correct system charging.
Outdoor units with indoor coils not listed are not
recommended. Deviations from rated airflows or non-
listed combinations may require modification to the

The refrigerant charge can be checked and adjusted
through the service ports provided external to the
outdoor unit. Use only gage line sets which have a
“Schrader” depression device present to actuate the

3. Verify HI and LO refrigerant pressures.
4. Allow the system to operate for several minutes
and then set the temperature selector above room

stop unless fan mode is set to the ON position.
System Heating (optional)
•
1. Set the thermostat's system mode to HEAT and the
temperature mode above room temperature.
2. Verify the optional heating equipment (furnace or

being circulated by the indoor blower and verify that
it is warmer than ambient temperature. Listen for any
unusual noises. If unusual sounds occur, determine
the source of the noise and correct as necessary.

3. Determine the required liquid refrigerant pressure.
Refer to Tables 4 - 10 (pages 13 - 16) for correct
system charging.
•
If the pressure measured in Step 1 is greater than
the required liquid refrigerant pressure determined in
Step 3, then there is too much charge in the system.
Remove refrigerant and repeat Steps 1 through 3 until
the system is correctly charged.
•
If the pressure measured in Step 1 is less than the
required liquid refrigerant pressure determined in

1. Disconnect all power before servicing.
2. For supply connections use copper conductors only.
to “H” on capacitor
RED
3. Not suitable on systems that exceed 150 volts to ground.
4. For replacement wires use conductors suitable for 105 deg C.
5. For ampacities and overcurrent protection, see unit rating plate.
6. Connect to 24 vac/40ca/class 2 circuit. See furnace/airhandler installation
instructions for control circuit and optional relay/transformer kits.
7. Anti-Short Cycle Timer (ASCT) may or may not be installed in the unit. If desired,
ASCT is factory installed on select models only or may be field installed as shown using
manufacturer’s approved kit. If not present, connect Yellow and Black wires per Note 6.
8. DO NOT use a Hard Start Kit on a model with a PTCR installed.
