VRV IV-S System air conditioner

9.13. 2 procedures for adding refrigerant

Procedure 1: Charging while the outdoor unit is at a standstill

See 

figure 6

 for Sky Air or room air conditioner applications or

figure 7

 for VRV applications.

1

Determine the weight of refrigerant to be charged additionally
referring to the item "Additional refrigerant charge" in 

"How to

calculate the additional refrigerant to be charged" on page 12

 for

Sky Air or room air conditioner applications or 

"How to calculate

the additional refrigerant to be charged" on page 13

 for VRV

applications, and fill in the amount in the "Additional refrigerant
charge label" attached to the unit.

2

After the vacuum drying is finished, open valve A and charge the
additional refrigerant in its liquid state through the liquid stop
valve service port taking into account following instructions:

-

Turn on the power of the outdoor unit and indoor units.

-

Check that gas and liquid stop valves are closed.

-

Stop the compressor and charge the specified weight of 
refrigerant.

Procedure 2: Charging while the outdoor unit is operating

1

Close the front panel and turn on the power to all indoor units
and the outdoor unit.

2

Completely open the gas side stop valve and liquid side stop
valve. Valve A must be left fully closed.

3

Open valve A immediately after starting of the compressor.

4

Charge the additional refrigerant in its liquid state through the
service port of the liquid line stop valve.

5

While the unit is at a standstill and under setting mode 2 (refer to

"11.2. Checks before initial start-up" on page 20

"Setting the

mode" on page 21

), set the required function A (additional

refrigerant charging operation) to 

 (ON). Then operation

starts. The blinking H2P led indicates test operation and the
remote controller indicates 

 (test operation) and 

(external control).

6

When the specified amount of refrigerant is charged, push the

 button. Then operation stops.

The operation automatically stops within 30 minutes.

If the refrigerant charge cannot be finished within 30 minutes,
repeat step 

5

.

If the operation stops immediately after restart, there is a
possibility that the system is overcharged.
The refrigerant cannot be charged more than this amount.

7

After the refrigerant charge hose is removed, make sure to close
valve A.

To avoid compressor breakdown. Do not charge the
refrigerant more than the specified amount.

If the total refrigerant cannot be charged while the
outdoor unit is at a standstill, it is possible to charge
the refrigerant by operating the outdoor unit using the
refrigerant charge function (refer to 

"Setting mode 2"

on page 21

) and follo

"Procedure 2: Charging while

the outdoor unit is operating" on page 16

.

ON

BS3  RETURN

All wiring must be performed by an authorized
electrician.

All field supplied components and all electric
construction should comply with the applicable local
and national codes.

To persons in charge of electrical wiring work:

Do not operate the unit until the refrigerant piping is
complete. (Running it before the piping is ready will break
the compressor.)
