SPECIAL PRECAUTIONS
WARNING 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 over- heating at connection points and a possible fire hazard.
When Transporting
Be careful when picking up and moving the indoor and out- door units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin alu- minum fins on the air conditioner can cut your fingers.
When Installing…
…In a Ceiling or Wall
Make sure the ceiling/wall is strong enough to hold the unit’s weight. It may be necessary to construct a strong wood or metal frame to provide added support.
…In a Room
Properly insulate any tubing run inside a room to prevent “sweating” that can cause dripping and water damage to walls and floors.
When Connecting Refrigerant Tubing
•Do not add any refrigerant, air, or substance into the refrigeration circuit other than the designated refrigerant (R410A). Adding anything other than the specified refrig- erant may cause the pressure to rise excessively in the refrigeration circuit, rupturing the circuit and causing injury or damage.
•Use
•Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then tighten the nut with a torque wrench for a
•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.
Others
CAUTION
•Ventilate any enclosed areas when installing or testing the refrigeration system. Escaped refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.
•Confirm upon completing installation that no refrigerant gas is leaking. If escaped gas comes in contact with a stove, gas water heater, electric room heater or other heat source, it can produce dangerously toxic gas.
