ELECTRICAL SHOCK HAZARD!
Turn OFF electric power before connecting unit,
performing any maintenance or removing
panels or doors. More than one disconnect
may be required to turn off all power.
FAILURE TO DO SO COULD RESULT IN BODILY
INJURY OR DEATH.
Be sure to check all local codes to determine that the unit
is installed in accordance with local requirements. Consult
the National Electric Code for wire size requirements. Use
60 / C or higher copper wires only. Always provide ground
connections to the outdoor unit. Power supply must agree
with rating on unit nameplate.
Provide line voltage power supply to unit from a properly
sized disconnect switch. Route power and ground wires
from disconnect switch to unit. Line voltage connections
are made at the line side of the contactor in the control box
of the outdoor unit. Follow the wiring diagram attached to
inside of the access panel.
Proper circuit protection recommendations are indicated
on Unit Rating Plate. Time delay fuses are required to
prevent blowing due to starting current (the current in rush
when equipment starts is referred to as the Locked Rotor
Amps or (LRA).
Remove access panel to gain access to unit wiring.
Extend wires from disconnect through power wiring hole
provided and into unit control box. Flexible conduit is
required for the swing out control box feature.
. . . .
The unit cabinet must have an uninterrupted or
unbroken ground. The ground must be installed in
accordance with all electrical codes. Failure to follow
this warning can result in an injury, fire, or death.
Connect ground wire to ground connection in control box
for safety. Connect power wiring to contactor.
High voltage power connections to 3-phase models is
made to "Pig Tail" leads with field supplied splice
connectors.
Control Wiring
The control voltage is 24 Vac. NEC Class I insulated 18
AWG is required for control wiring. For lengths longer than
150 feet, contact your local distributor for technical service.
Ensure the room thermostat is properly installed per
instructions shipped with room thermostat. Generally the
506320-01
thermostat should not be exposed to sunlight, drafts or
vibration and should not be mounted on exterior walls.
Low voltage wiring must be separated from high
voltage wiring.
Low voltage connections should be in accordance to the
wiring diagram.
Typical Low Voltage Connection
Start-Up Procedure
1. Close electrical disconnects to energize system.
2. Set room thermostat at desired temperature. Be
sure set point is below indoor ambient temperature.
3. Set the system switch of the thermostat on COOL
and fan switch for continuous operation (ON) or
AUTO, as desired.
4. Adjust refrigerant charge per "Adjusting Charge"
section.
Adjusting Charge
Factory charge is shown on the rating label located on
the access panel.
All units are
connecting line set. Charge should be adjusted for line
set lengths other than 15 feet. For line sets shorter than 15
feet in length, remove charge. For line sets longer than 15
feet, add charge. Oil charge is sufficient for all line lengths.
Refrigeration Charge Adjustment
Liquid Line Diameter
3/8"
Before final adjustment is made to the refrigerant charge,
check for proper indoor airflow. Recommended airflow is
350-450 CFM per ton (12,000 Btuh) through a wet coil.
Refer to indoor unit instructions for methods of determining
air flow and blower performance.
