Infinityr Air Conditioner with Puronr Refrigerant

1---1/2 to 5 Nominal Tons (Siz e 18---60)

Wiring Diagram

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, 24V circuit, min. 40VA required, 60VA on units installed with LLS.

4. Use copper conductors only from disconnect to unit suitable for at least 75ºC (165ºF).

5. For communicating control only.

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. In case of non-communicating Indoor system, disconnect factory provided wires from A,B,C, and D

terminals. Using factory provided wires, connect to R, C and/or Y Terminals per installation

instructions. Connect field 24V wires to factory provided wires, cap or remove unused factory provided

wires.

CONNECTION DIAGRAM

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.

CAUTION

CONDENSING UNIT CHARGING INSTRUCTIONS

For use with units using R-410A refrigerant

COOLING ONLY

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.
