Charging method

As explained during vacuum drying method, once vacuum drying is
finished, additional refrigerant charging can start.

Follow the steps as described below.

1

Calculate the amount of refrigerant to be added using the
formula mentioned in 

"13.3. Calculating the additional refrigerant

charge" on page 23

The first 10 kg of refrigerant can be charged without outdoor unit
operation. If the additional refrigerant amount is smaller than
10 kg, perform the precharging procedure as explained in step 

2

below. If the additional refrigerant charge is larger than 10 kg,
perform step 

2

 and perform step 

3

 till the end of the procedure.

2

Precharging can be done without compressor running by
connecting the refrigerant bottle only to the liquid stop valve. 

Make sure that the stop valves are closed:

3

If the total amount of refrigerant could not be charged by
precharging, then connect the refrigerant bottle to the refrigerant
charging port as described in the figure above.

4

Make sure to open the discharge gas pipe stop valve and liquid
pipe stop valve of the outdoor unit. Keep the suction gas stop
valved of the outdoor unit ALWAYS closed. Refer to 

"How to use

the stop valve" on page 16

.

5

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

Take all the precautions mentioned in 

"14. Start-up  and

configuration" on page 25

 into account. 

To be able to do this operation, the outdoor unit should be set in
mode 2. Refer to 

"Field settings by push buttons" on page 26

 for

further explanation on how to do the necessary settings.

6

Push the 

BS1 MODE

 button for 5 sec, the H1P LED is on 

w

.

7

Push the 

BS2 SET

 button 20 times until following LED

combination is reached:

8

Push the 

BS3 RETURN

 button to confirm setting 2-20 above.

9

Push the 

BS2 SET

 button to change the charge mode from 

OFF

(OFF) to 

ON

 (ON). LED indication should change as follows

10

Push the 

BS3 RETURN

 button and the setting is defined.

11

Push the 

BS3 RETURN

 button again, and the refrigerant

charging operation will start.

12

After charging the specified quantity of refrigerant, press the

BS3 RETURN

 button to stop the operation.

Checks after adding refrigerant

Are the stop valves for liquid and discharge open?

Is the amount of refrigerant, that has been added, recorded on
the refrigerant charge label?

NOTE

The operation will automatically stop within 30
minutes. If charging is not completed after 30 minutes,
set and perform the additional refrigerant charging
operation again.

Make sure to open the stop valves after charging the
refrigerant but keep the suction stop valve closed at
all times.

Operating with the stop valves closed will damage the
compressor.
