IMPORTANT!Please read before installation
This air conditioning system meets strict safety and operatingstandards.For the installer or service person, it is important to install orservice 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.
This symbol refers to a hazard or unsafe practice which can resultin severe personal injury or death.
This symbol refers to a hazard or unsafe practice which can resultin personal injury or product or property damage.
If necessary, get helpThese instructions are all you need for most installation sites andmaintenance conditions.If you require help for a special problem, contact our sale/serviceoutlet or your certified dealer for additional instructions.
In case of improper installationThe manufacturer shall in no way be responsible for improperinstallation or maintenance service, including failure to follow theinstructions in this document.
SPECIAL PRECAUTIONS
During installation, connect before the refrigerant system andthen the wiring one; proceed in the reverse orden when removingthe units.
When wiring
ELECTRICAL SHOCK CAN CAUSE SEVEREPERSONAL INJURY OR DEATH. ONLY A QUALIFIED,EXPERIENCED ELECTRICIANS SHOULD ATTEMPTTO WIRE THIS SYSTEM.
Do not supply power to the unit until all wiring and tubing arecompleted 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 whenwiring.Improper connections and inadequate grounding can causeaccidental 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 transportingBe careful when picking up and moving the indoor and outdoorunits. Get a partner to help, and bend your knees when lifting toreduce strain on your back. Sharp edges or thin aluminium fins onthe air conditioner can cut your fingers.
When installing...... In a ceiling or wallMake sure the ceiling/wall is strong enough to hold the unit-weight.It may be necessary to build a strong wooden or metal frame toprovide added support.
... In a roomProperly insulate any tubing run inside a room to prevent"sweating", which can cause dripping and water damage to wallsand floors.
... In moist or uneven locationsUse a raised concrete base to provide a solid level foundation forthe outdoor unit.This prevents damage and abnormal vibrations.
... In area with strong windsSecurely anchor the outdoor unit down with bolts and a metalframe. 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 thandrifting 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 andthen tighten the nut with a torque wrench for a leak-freeconnection.
Check carefully for leaks before starting the test run.
NOTE:Depending on the system type, liquid and gas lines may be eithernarrow or wide. Therefore, to avoid confusion, the refrigeranttubing for your particular model is specified as narrow tube forliquid, 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 beingserviced.
Ventilate the room during the installation or testng the refrigerationsystem; make sure that, after the installation, no gas leaks arepresent, because this could produce toxic gas and dangerousif in contact with flames or heat-sources.
