1. Compressor and fan motor furnished with inherent thermal protection.
2. To be wired in accordance with National Electric Code (N.E.C.) and local codes.
3. N.E.C. Class 2, 24 V circuit, min. 40 VA required, 60VA on units installed with LLS.
4. Use copper conductors only from disconnect to units suitable for at least 75ºC (167ºF).
5. Must use thermostat and sub-base as stated in pre-sale literature.
6. If indoor section has a transformer with a grounded secondary, connect the Grounded
side to "C" on the circuit board.
7. If any of the original wire, as supplied, must be replaced, use the same or equivalent wire.
8. Check all electrical connections inside control box for tightness.
9. Do not attempt to operate unit until service valves have been opened.
10. Symbols are electrical representation only.
11. When start relay and start capacitor are installed, start thermistor is not used.
12. For communicating control only.
13. In case of non-communicating Indoor system, disconnect factory provided wires from DX+, DX-, C and
R terminals. Using factory provided wires connect to R, C, Y, W2, and O terminals as required by
Installation Instructions. Connect field 24V wires to factory provided wires, cap or remove unused
factory provided wires.

1. Compressor damage may occur if system is over charged.
2. This unit is factory charged with R-410A in accordance with the amount shown on
the rating plate. The charge is adequate for most systems using matched coils
and tubing not over 15 feet long. Check refrigerant charge for maximum efficiency.
See Product Data Literature for required Indoor air Flow Rates and for use of line
lengths over 15 feet.
3. Relieve pressure and recover all refrigerant before system repair or final disposal.
Use all service ports and open all flow-control devices, including solenoid valves.
4. Never vent refrigerant to atmosphere.
Use approved recovery equipment.

CHARGING PROCEDURE
1. Only use subcooling charging method
when OD ambient is greater than 70ºF
and less than 100ºF, indoor temp is
greater than 70ºF and less than 80ºF,
and line set is less than 80 ft.
2. Operate unit a minimum of 15 minutes
before checking the charge.
3. Measure liquid service valve pressure
by attaching an accurate gauge to the
service port.
4. Measure the liquid line temperature by
attaching an accurate thermistor type
or electronic thermometer to the
liquid line near the outdoor coil.
5. Refer to unit rating plate for required
subcooling temperature.
6. Find the point where the required
subcooling temperature intersects the
measured liquid service valve pressure.
7. To obtain the required sub-cooling
temperature at specific liquid line
pressure, add refrigerant if liquid line
temperature is higher than indicated.
When adding refrigerant, charge in
liquid form using a flow restricting
device into suction service port.
Recover refrigerant if temperature is
lower. Allow a tolerance of +/- 3ºF.
