SELECTING AN ADDITIONAL REFRIGERANT CHARGE
The basic amount of refrigerant for outdoor units charged in the factory is:
OUTDOOR UNIT (SERIES) FACTORY CHARGE (kg)
IGLU® Inuit 6I/ IGLU® Inuit 6WTI 1.2
IGLU® Inuit 9I/ IGLU® Inuit 9WTI 1.4
IGLU® Inuit 12I/ IGLU® Inuit 12WTI 2.98
IGLU® Inuit 16I/ IGLU® Inuit 16WTI 2.98

Charge additional refrigerant according to the total length of the pipe.

Each factory charging values are determined according to a basic pipe length of 15 m.

When extra pipe lengths are required, additional charging works must be implemented as described below.
REFRIGERANT CHARGING
Additional charging amount is determined based on liquid pipe specifications.

*L1-TOTAL LENGTH OF LIQUID PIPE
EXAMPLES:
IGLU® Inuit 6I, the total length of the liquid pipe is 20m.
ø6.35=(20m-15m) x20g/m=100 g.
IGLU® Inuit 12I, the total length of the liquid pipe is 20m.
ø 9.52=(20m-15m) x50g/m=250 g.

The R-410A refrigerant is blended. Add only liquid refrigerant.

Measure the quantity of the refrigerant according to the length of the liquid side pipe. Add the quantity of the
refrigerant using a scale.
