your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum 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.
● 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 abnormal vibration.
● In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable air baffle.
● In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow. Provide snow vents.
When Connecting Refrigerant Tubing
△ 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 connection.
△ 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
△ 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.
