IMPORTANT!
Please Read Before Starting
This air conditioning system meets strict safety and operating standards. As the installer or service person, it is an important part of your job to install or service the system so it operates safely and efficiently.
For safe installation and trouble-free operation, you must:
●Carefully read this instruction booklet before beginning
●Follow each installation or repair step exactly as shown
●Observe all local, state, and national electrical codes
●Pay close attention to all warning and caution notices given in this manual
This symbol refers to a hazard WARNING: or unsafe practice which can
result in severe personal injury or death.
This symbol refers to a hazard
CAUTION: or unsafe practice which can result in personal injury or
product or property damage.
If Necessary, Get Help
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.
In Case of Improper Installation
The manufacturer shall in no way be responsible for improper installation or maintenance service, including failure to follow the instructions in this document.
SPECIAL PRECAUTIONS
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 overheating at connection points and a possible fire hazard.
When Transporting
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.
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 unit down with bolts and 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
•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 connection.
•Check carefully for leaks before starting the test run.
NOTE:
Depending on the system type, liquid and gas lines may be either narrow or wide. Therefore, to avoid confusion the refrigerant tubing for your particular model is specified as either “narrow” or “wide” rather than as “liquid” or “gas.”
When Servicing
•Turn the power OFF at the main power box (mains) before opening the unit to check or repair electrical parts.
•Keep your fingers and clothing away from any moving parts.
•Clean up the site after you finish, remembering to check that no scraps or bits of wiring have been left inside the unit being serviced.
