IMPORTANT!
Please read before installation
This air conditioning system meets strict safety and operating standards.
For the installer or service person, it is important to install or service the system so that 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.
•The unit must be supplied with a dedicated electrical line.
WARNING
This symbol refers to a hazard or unsafe practice which can result in severe personal injury or death.
CAUTION
This symbol refers to a hazard 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 sale/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
•During installation, connect before the refrigerant system and then the wiring one; proceed in the reverse orden when removing the units.
WARNING |
When wiring |
ELECTRICAL SHOCK CAN CAUSE SEVERE PERSONAL INJURY OR DEATH. ONLY QUALIFIED, EXPERIENCED ELECTRICIANS SHOULD ATTEMPT TO WIRE THIS SYSTEM.
•Do not supply power to the unit until all wiring and tubing are completed or reconnected and checked, to ensure the grounding.
•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 and death.
•Ground the unit following local electrical codes.
•The Yellow/Green wire cannot be used for any connection different from the ground connection.
•Connect all wiring tightly. Loose wiring may cause overheating at connection points and a possible fire hazard.
•Do not allow wiring to touch the refrigerant tubing, compressor, or any moving parts of the fan.
•Do not use multi-core cable when wiring the power supply and control lines. Use separate cables for each type of line.
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 aluminium fins on the air conditioner can cut your fingers.
When installing...
… In a ceiling
Make sure the ceiling is strong enough to hold the unit-weight. It may be necessary to build a strong wooden or metal frame to provide added support.
… In a room
Properly insulate any tubing run inside a room to prevent "sweating", which can cause dripping and water damage to walls and floors.
... In moist or uneven locations
Use a raised concrete base to provide a solid level foundation for the outdoor unit. This prevents damage and abnormal vibrations.
... In area with strong 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 then 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; screw by hand and 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 narrow tube for liquid, wide tube for gas.
When servicing
•Turn the power OFF at the main power board 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 the work, remembering to check that no metal scraps or bits of wiring have been left inside the unit being serviced.
•Ventilate the room during the installation or testing the refrigeration system; make sure that, after the installation, no gas leaks are present, because this could produce toxic gas and dangerous if in contact with flames or heat-sources.
