WARNINGS!
ELECTRICAL SAFETY PRECAUTIONS
1. Disconnect power supply prior to ANY work.
2. The air conditioner is a specialized circuit that requires
its own power supply – this is not to be shared with ANY
other electrical appliances.
3. The air conditioner should be installed in a suitable
location and the power supply should be easily reachable
by ALL users.
4. During maintenance and installation, make sure wiring
terminals are securely fastened.
5. Ground wire MUST be firmly connected and NOT used
for other purposes.
6. Use protective accessories as necessary, (IE: protective
boards, cable-cross loop, wire clips, etc.).
7. Live wire, neutral wire, and ground wire MUST
correspond to the live wire, neutral wire, and ground wire
of the air conditioner.
8. Power cord and power connections MUST be free of
obstruction and CANNOT be compressed.
9. Should power cord or power connection become severed,
they MUST be repaired/replaced by qualified technician.
10. If the power cord or power connection wire is not
long enough, replace with specialized cable from
manufacturer before proceeding with installation or
repair. DO NOT elongate these wires.
11. An air switch MUST be installed if there is no plug found
on the air conditioner. The air switch MUST be all-pole
parting and the contact parting distance MUST be at
1/8” or greater.
12. All wires and pipes MUST be connected firmly prior to
supplying the unit with power.
13. Eliminate any electric leakage on the unit body.
14. Fuses MUST be replaced with fuse of the same
specification(s). DO NOT replace with copper wire or
conducting wire.
15. If the unit is being installed in a humid climate, a circuit
breaker MUST also be installed.
INSTALLATION SAFETY PRECAUTIONS
1. Select installation location according to the requirements
of this manual. (See the requirements of installation
section in this manual.).
2. Handle unit with care. If unit exceeds 44.09 pounds, use
the two-person lift technique to transport.
3. Use a sufficient fixing bolt when installing both the
indoor and outdoor unit(s). Ensure installation support is
firm.
4. Use safety belt and personal protection equipment
(PPE) while working above a height of 6’.
5. Use equipped components or appointed components
during installation.
6. Make sure to clear the unit of any/all foreign objects prior
to completion of installation.
REFRIGERANT SAFETY PRECAUTIONS
1. Avoid contact of fire and refrigerant as the combination
creates poisonous gas.
2. Use only specified refrigerant. DO NOT mix refrigerant
types. DO NOT allow air to remain in refrigerant lines as
this may lead to pipe rupture or other hazards.
3. Check entire system for refrigerant leaks prior to
completing installation.
Improper installation may lead to fire hazard,
explosion, electric shock or injury.
