2) The unit must be grounded for safety in accordance with local

electrical codes. (Grounding resistance should be under 100 ohms)

CAUTION

•Use designated diameter and thickness of tube.

•Connect all tube as short as possible and fix firmly.

•Less than 3M of the difference of height between indoor

and outdoor unit is desirable.

•Fill up more refrigerant if the connection tube is longer

than 5M (50g/M).

(The refrigerant volume filled from the factory is suitable

for 5M connection)

•Be careful not to let in any dust or motes into the tube

when the tube passes the wall.

•When insulating the connection, use foam rubber or
