Safety Instructions
Special Precautions
DANGER
When Wiring
● Do not supply power to the unit until all wiring and tubing are completed or recon-
nected and checked.
● Highly dangerous electrical voltages are used in this system. Carefully refer to the
wiring diagram and these instructions when wiring. Improper connections and inad-
equate grounding can cause accidental injury or death.
● Ground the unit following local electrical codes.
● Connect all wiring tightly. Loose wiring may cause overheating at connection points
and a possible fire hazard.
● A power supply should be provided exclusively for each unit, complete with circuit
breaker and over current protection.
● Provide a power outlet exclusively for each unit, and full disconnection means, with
contact separation in all poles, must be incorporated in the fixed wiring, in accord-
ance with the wiring rules.
● To prevent possible hazards from insulation failure, the unit must be grounded.
● This equipment is strongly recommended to be installed with Earth Leakage Circuit
Breaker (ELCB) or Residual Current Device (RCD). Otherwise, it may cause elec-
trical shock and fire in case of equipment break down or insulation breakdown.
When Transporting
Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and
bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins
on the products may cause injury, such as cuts to hands or fingers.
When Installing
Select an installation location which is rigid and strong enough to support or hold the unit, and
select a location for easy maintenance.
In a Room
Properly insulate any tubing run inside a room to prevent condensation "sweating" that can
cause dripping and water damage to walls and floors.
12
Electrical shock can cause severe personal injury or death.
Only a qualified, experienced electrician should attempt to wire this system.
