Refrigerant Piping Connection
BEFORE PERFORMING ELECTRICAL WORK, READ THESE REGULATIONS
DO NOT connect another appliance to the outlet for the unit. Only connect the unit to an
individual branch circuit outlet.
DO NOT allow wires to touch or rest against the refrigerant piping, compressor, or any other
moving parts within the unit.
1. All wiring must comply with local and national electrical codes, regulations, and must be installed by a
licensed electrician.
2. All electrical connections must be made according to the Electrical Connection Diagram located on the
panels of the indoor and outdoor units.
3. If there is a serious safety issue with the power supply, stop work immediately. Explain the issue to the
client, and refuse to continue the installation until the safety issue is properly resolved.
4. Power voltage should be within 90-110% of the rated voltage. An insufficient power supply can cause a
malfunction, electrical shock, and/or fire.
5. If connecting power to fixed wiring, a surge protector and main power switch should be installed.
6. The circuit, including any switches, should have a capacity 1.5 times the maximum unit current (amps).
7. A qualified technician must use an approved circuit breaker or switch that disconnects all poles and has a
contact separation of at least 1/8 in (3 mm) incorporated in the fixed wiring.
8. Make sure the unit/system is properly grounded.
9. Every wire must be firmly and securely connected. Loose wiring can cause the terminal to overheat,
which could result in a malfunction and/or fire.
10. If the unit has an auxiliary electric heater, it must be installed as least 40 in (1 m) away from
combustible materials.
11. To avoid electrical shock, never touch the electrical components soon after the power supply has been
turned off. Always wait 10 minutes or more before touching the electrical components once the power
has been turned off.
