Do not supply power to the unit until all wiring and tubing are completed or reconnected and 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 the unit following local electrical all wiring tightly.

5 Loose wiring may cause overheating at connection points and a possible fire a protective leakage breaker depending on the installation location (especially a damp or humid location). If a leakage breaker is not installed, electric shock can TransportingBe 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.

6 It may be necessary to construct a strong wood or metal frame to provide added a RoomProperly insulate any tubing run inside a room to prevent "sweating" that can cause dripping and water damage to walls and Moist or Uneven LocationsUse a raised concrete pad or concrete blocks to provide a solid, level foundation for the outdoor unit. This prevents water damage and abnormal an Area with High WindsSecurely 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.

7 Provide snow Connecting Refrigerant TubingUse the flare method for connecting 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 carefully for leaks before starting the test ServicingTurn the power off at the main power box (mains) before opening the unit to check or repair electrical parts and your fingers and clothing away from any moving up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left inside the unit being any enclosed areas when installing or testing the refrigeration system.

8 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. 2 Table of Contents APPLICABLE INDOOR UNITS1.
