1-3. Additional Materials Required for
Installation (not supplied)
1.
Refrigeration (armoured) tape
2.
Insulated staples or clamps for connecting wire
(See your local codes.)
3.
Putty
4.
Refrigeration tubing lubricant
5.
Clamps or saddles to secure refrigerant tubing
CAUTION
• Check local electrical
codes and regulations
before connecting wire.
Also, check any
specified instructions
or limitations.
DO:
• select an appropriate position from which every corner of
the room can be uniformly cooled.
• select a location where the ceiling is strong enough to support
the weight of the unit.
• select a location where tubing and drain pipe have the
shortest run to the outside.
• allow room for operation and maintenance as well as
unrestricted air flow around the unit.
• install the unit within the maximum elevation difference (H)
above or below the outdoor unit and within a total tubing
length (L) from the outdoor unit as detailed in the section 6.
NOTE
Air delivery will be degraded if the distance from the floor to
the ceiling is greater than 3 m.
2. INSTALLATION SITE SELECTION
AVOID:
• areas where leakage of flammable gas may be expected.
• places where large amounts of oil mist exist.
• direct sunlight.
• location where nearby heat sources may affect performance
of the unit.
• locations where nearby external air may enter the room
directly. This may cause “sweating” in the air discharge ports,
causing them to spray or drip.
• location where the remote controller will be splashed with
water or affected by dampness or humidity.
• installing the remote controller behind curtains or furniture.
