Installation site selection - Indoor unit
AVOID
• Direct sunlight.
• Nearby heat sources that may affect unit performance.
• Areas where leakage of flammable gas may be expected.
• Locations where large amounts of oil mist may occur
(such as in kitchen or near factory equipment) because
oil contamination can cause operation problems and may
deform plastic surfaces and parts of the unit.
• Unsteady locations that will cause noise or possible water
leakage.
• Locations where the remote control unit will be splashed
with water or affected by dampness or humidity.
• To make holes in areas where electrical wiring or conduits
are located.
DO
• Select an appropriate position from which every corner of
the room can be uniformily cooled.
• Select a sufficiently strong location to support the weight
of the unit.
• Select a location where tubing and drain hose have the
shortest run to the outside.
• Allow access for operation and maintenance as well as
unrestricted air flow around the unit.
Installation site selection - Outdoor unit
AVOID
• Heat sources, exhaust fans.
• Direct sunlight.
• Damp, humid or uneven locations.
• To make holes in areas where electrical wiring or conduits
are located.
DO
• Choose places as cool as possible and well ventilated.
• use lug bolts or equal to bolt down the unit, reducing
vibration and noise.
ADDITIONAL MATERIAL REQUIRED FOR INSTALLATION (NOT SUPPLIED)
●
Deoxidized annealed copper tube for refrigerant tubing connecting the units of the system; it has to be insulated with
foamed polyethylene (min. thickness 8mm).
●
PVC pipe for condensate drain pipe (ø int.18mm) in lenght suitable to let the condensate flow into the outside drainage.
●
Anti-freeze oil for flare connections (about 30g).
●
Electric wire: use insulated copper wires of size and length as shown in the table “ELECTRICAL DATA” and at paragraph
“SYSTEM WIRING DIAGRAMS”.
