These instructions are all you need for most installation 
sites and maintenance conditions. If you require help for a 
special problem, contact our sales/service outlet or your 
certified dealer for additional instructions. 

The manufacturer shall in no way be responsible for 
improper installation or maintenance service, including fail-
ure to follow the instructions in this document. 

•  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 inad-
equate 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.

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 fingers. 

Properly insulate any tubing run inside a room to prevent 
“sweating” that can cause dripping and water damage to 
walls and floors.

Use a raised concrete pad or concrete blocks to provide 
a solid, level foundation for the outdoor unit. This prevents 
water damage and abnormal vibration.

Securely anchor the outdoor unit down with bolts and a 
metal frame. Provide a suitable air baffle.

Install the outdoor unit on a raised platform that is higher 
than drifting snow. Provide snow vents.

•  Ventilate the room well, in the event that is refrigerant 

gas leaks during the installation. Be careful not to allow 
contact of the refrigerant gas with a flame as this will 
cause the generation of poisonous gas.

•  Keep all tubing runs as short as possible.

•  Use the flare method for connecting tubing.

•  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 leak-free con-
nection.

•  Check carefully for leaks before starting the test run.

•  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.

•  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 after installation that no refrigerant gas is leak-

ing. If the gas comes in contact with a burning stove, gas 
water heater, electric room heater or other heat source, 
it can cause the generation of poisonous gas.
