Run all line voltage wiring a conduit from the service discon-
nect box to the unit. Refer to the NEC (USA) or CEC (Canada)
codes for the correct size conduit based on the wire size.
The conduit enters the control box through the hole provided
in the bottom.
NOTE: The control box hole is sized for 3/4”
conduit. If permitted by code, a flexible conduit is preferred to
minimize vibration transmission from the unit to the building.
Connect the line voltage wires to the L1, L2, and L3 termi-
nals of the definite purpose contactor (located in the unit con-
trol box). Refer to the wiring diagram attached to the unit
when making these connections.
Three Phase Compressor Rotation
Use care when handling scroll compressors. Dome temp-
eratures could be hot.
CAUTION
Three phase scrolls are power phase dependent and can
compress in more than one direction.
Verify proper rotation for three phase compressors by ensur-
ing the suction pressure drops and discharge pressure rises
when the compressor is energized.
NOTE: When operated
in reverse, a three phase scroll compressors is noisier and
its current draw substantially reduced compared to marked
values.
To correct, disconnect power and switch any two leads at
the unit contactor and re-observe.
High Voltage Connections
Route power supply and ground wires through the high volt-
age port and terminate in accordance with the wiring dia-
gram provided inside the control panel cover.
Low Voltage Connections
Condensing unit control wiring requires a five-conductor low
voltage circuit from the room thermostat (without options).
The wires should be no smaller than 18 AWG and the field
connection for this circuit must be made in the unit control
box using solderless connectors (i.e. wire nuts). See the fol-
lowing diagram for a typical low voltage hook-up.

System Start Up
Never operate the compressor with the suction valve closed
to test the compressor’s pumping efficiency. In some cases,
this can result in serious compressor damage and loss of
warranty coverage.
NOTICE
THIS UNIT IS SHIPPED WITH A NITROGEN/HELIUM
HOLDING CHARGE ONLY. UNIT MUST BE
EVACUATED AND CHARGED PER INSTALLATION
INSTRUCTIONS WITH REFRIGERANT LISTED ON
SERIAL RATING PLATE.
UNITS SHIPPED WITH A HOLDING CHARGE ARE
INTENDED FOR COMPONENT REPLACEMENT
ONLY ON EXISTING SYSTEMS, AND NOT
INTENDED FOR USE IN NEW SYSTEMS OR NEWLY
CONSTRUCTED HOMES.
NOTICE
NOTICE
UNITS MUST ONLY BE USED AS REPLACEMENT
COMPONENTS FOR PRE-2010 INSTALLED
SYSTEMS.
For the 7-1/2 ton unit starting charge should be 15 lb of R-22
and 18 lbs for the 10 ton unit. The length of line set, indoor
unit airflow, condensing unit location and number of tubing
fittings will have an impact on final unit charge amount. Turn
the electrical power on, and let the system run. Wait for the
refrigerant pressures to stabilize.
Charge Verification
REFRIGERANT UNDER PRESSURE!
• Do not overcharge system with refrigerant.
• Do not operate unit in a vacuum or at negative pres-
sure.
Failure to follow proper procedures may cause
property damage, personal injury or death.
