Safety Precautions
NOTE TO INSTALLING DEALER: The Owners Instructions and Warranty are to be given to the owner
: Improper installation, adjustment, alteration, service or maintenance can void the warranty.
The weight of the condensing unit requires caution and proper handling procedures when lifting
or moving to avoid personal injury. Use care to avoid contact with sharp or pointed edges.
• Always wear safety eye wear and work gloves when installing equipment.
• Never assume electrical power is disconnected. Check with meter and equipment.
• Keep hands out of fan areas when power is connected to equipment.
• R-410A causes frostbite burns.
• R-410A is toxic when burned.
or prominently displayed near the indoor Furnace/Air Handler Unit.
When wiring:
Electrical shock can cause severe personal injury or death. Only a qualified,
experienced electrician should attempt to wire this system.
• Do not supply power to the unit until all wiring and tubing are completed or reconnected 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 inadequate 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.
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 air conditioner can cut your finger.
When installing...
... in a wall: Make sure the wall is strong enough to hold the unit's weight.

When connecting refrigerant tubing
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Check carefully for leaks before starting the test run.
When servicing
• Turn the power OFF at the main power box(mains) before opening the unit to check or repair
electrical parts and wiring.
• Keep your fingers and clothing away from any moving parts.
• Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have
been left inside the unit being serviced.

• The wire should not be exposed to the outside otherwise it may leads to the malfunction
of the independent power kit due to wire damage.
• Wrong wiring also causes the malfunction of the independent power kit or damage to it.
• Power should be supplied more than 20 minutes continuously in order to operate the
independent power kit correctly. Otherwise, the independent power kit can not fully close
the EEV due to the lack of the charging power.
WARNING
1. Turn the power off using circuit breaker.
2. Disconnect the EEV cable of the indoor unitʼs PCB(CN-EEV)
3. Connect the independent power kit(CN-EEV/LOAD) to the indoor unitʼs EEV, using
harness 1.
4. Connect the independent power kit(CN-EEV/MAIN) to the indoor unitʼs PCB(CNEEV/CN-WRITE), using harness 2 or 3.
5. Supply the power.
