When Transporting:
Be careful when picking up and moving indoor and outdoor units. Get a partner to help, and bend your knees when
lifting to reduce strain on your back. Watch for sharp edges or thin aluminum fins, as they 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 reinforce it using a strong
wood or metal frame to provide added support.
●
In a Room
Properly insulate any tubing run inside a room to prevent
“sweating” - condensation that can collect and drip, leading to
possible water damage to walls and floors.
●
In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents
water damage and unwanted vibration.
●
In an Area with High Winds
Securely anchor the outdoor unit down with bolts and additional framing (not supplied). Provide a suitable air baffle.
●
In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that will be higher than drifting snow. Provide snow vents.

When Connecting Refrigerant Tubing:
△
Use flare method for connecting tubing.
△
Apply refrigerant lubricant to matching surfaces of the flare and union tubes before connecting them, then tighten the
nut with a torque wrench for leak-free connection.
△
Check carefully for leaks before starting a 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:
△
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. As stated above, 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.

The figure, size, and parameters of the actual product may not be identical with the service manual;
