2. Refrigerant Oil Recovery Operation Flow

2.1 Refrigerant oil recovery operation monitor display

(*1) The initial remaining time that indicates the refrigerant oil recovery is 80. A countdown will start on step 3 in the cooling mode.

The countdown does not include the time for checking the refrigerant charge amount.

(*2) S-1: Refrigerant oil recovery complete, S-0: Refrigerant oil recovery incomplete,

r-1: Refrigerant charge adjustment complete, r-0: Refrigerant charge adjustment incomplete.

1. How to read the LED on the service monitor

Units' operation status can be monitored on the LED display by setting the dipswitches SW1-1 through 1-10 on the MAIN board of the

outdoor units.

Four 7-segment LEDs are used to display numerical values, flags, and alphabets to display various information.

The LEDs display such information as pressure and temperature in numerical values and operating conditions and the ON/OFF status of

solenoid valve as flags.

●Display of numerical values

Example:When the pressure sensor reads 18.8 kg/cm2G (Item No. 58)

* The unit of pressure is in kg/cm2G.

* Use the following conversion formula to convert the displayed value into a value in SI unit (MPa).

SI unit (MPa) = Displayed value (kg/cm2G) 0.098

●Flag display (Each set of two lines in vertical alignment indicates a flag.)

Example:Outdoor unit in the 3-minute restart delay mode. (Item No. 14)

2.2 Procedures for refrigerant oil recovery

1Evacuating the existing pipes, and ensuring air tightness

Charge airtight gas through the service port on both the high-pressure and low-pressure valves. The air tightness should be

4.15 MPa. After checking the air tightness, evacuate the air through the service port on both the high-pressure and low-pressure valves.

2Refrigerant charging

•If the length or diameter of the refrigerant pipe is unknown

Charge the required amount of refrigerant (indoor units + BC controllers) through both high-pressure and low-pressure service port valves.

•When refrigerant pipe diameter and length are already known

Charge the required amount of refrigerant (indoor units + BC controllers + pipes) through both the high-pressure and low-pressure service port

valves. See the table below for the required amount of refrigerant for the indoor units and BC controllers. To calculate the required amount of

refrigerant charged for the pipes, refer to 10.1. “Calculation of additional refrigerant charge” in the installation manual on the CD-ROM.

If there is excess refrigerant that cannot be charged, use it during oil recovery operation at step 4 (cooling operation).

* After charging the required amount of refrigerant to the existing pipes, open the valve so that the pressure in the existing pipes and outdoor unit

are equal. (Refer to Procedure 3.) Do not open the valve on the outdoor unit when the existing pipes are under vacuum. Doing so may cause

the refrigerant that is dissolved in the refrigerant oil in the compressor to form and cause some oil to migrate to the existing pipes, resulting in

insufficient lubrication.

3Opening the valves

Open both the high-pressure and low-pressure valves.

Use a hexagonal wrench to open the valves. Refer to the table below for the proper wrench size.

4Connecting the refrigerant cylinder(s)

If the required amount of refrigerant is not charged, disconnect the charging hose connected to the refrigerant cylinder from the

service port on high-pressure and low-pressure side, and connect the charging hose to the refrigerant charge port CJ3

(only for automatic charging).

* Check that each cylinder has the correct amount of refrigerant.

* If the amount of refrigerant is insufficient, the units may stop during refrigerant oil recovery or it may take longer than usual to complete a test

run.

5Setting the unit address and checking for proper system operation

Set the unit address, turn on the power, and check for proper operation of the system.

* If an attempt is made to operate the outdoor unit before the refrigerant oil recovery operation is complete, an error code 7116 will appear on the

remote controller. This does not indicate a malfunction. Wait for the oil recovery operation to be completed. The error code 7116 will go off upon

completion of oil recovery operation.

6Refrigerant oil recovery operation

Set the dipswitches 3-1 and 4-8 to ON in that order. The compressor turns on, and oil recovery operation starts.

The refrigerant oil recovery operation is explained in the next page. Wait for the operation to be automatically completed.

* If there was excess refrigerant that had not been charged at “2Refrigerant charging”, charge it during oil recovery operation at step 4 (cooling

operation). After charging the refrigerant, close the valve on the refrigerant cylinder. (Even when the required amount of refrigerant is already

charged, refrigerant charge is automatically adjusted.)

* If the cylinder runs out of refrigerant during the refrigerant oil recovery operation, continue the operation and replace the cylinder.

* If the cumulative oil recovery operation hour is more than three and a half hours, turn the dipswitches 4-8 and 3-1 to OFF to stop the operation

and turn the dipswitches 4-7 on the units (OC) to OFF.

Wait for the operation to be automatically completed.

*Refer to the table at right for the maximum amount of refrigerant charge.

Do not exceed the maximum amount.

If the refrigerant oil recovery operation does not finish after the maximum

amount of refrigerant is charged, close the valve on refrigerant cylinder, and wait

for the operation to be completed automatically.

* If the cylinder runs out of refrigerant during the refrigerant oil recovery operation,

continue the operation and replace the cylinder.

If more than the amount of refrigerant that you calculated is charged into the system in auto-charge mode, then there is no problem if you wish to

close the cylinder valve while the unit is operating. The unit will stop operating of its own accord.

If the length or diameter of the refrigerant pipe is known, please make note of the following.

7Check for successful completion of the refrigerant oil recovery operation.

Turn the dipswitches 1-4, 1-5, 1-6, and 1-7 to ON to verify that the refrigerant oil recovery operation is completed. “S-1” or “r-1” on

the outdoor unit’s LED indicates a successful completion.

“S-1” “r-1”: The refrigerant oil recovery operation is successfully completed. Go to the next procedure.

“S-1” “r-0”: The refrigerant charge adjustment is not completed, but regular air conditioning operation can be started. If there was excess

refrigerant that had not been charged, charge it through the low-pressure check joint (CJ2) during the air conditioning operation.

“S-0” “r-1”: The refrigerant oil recovery operation is not completed. To restart the refrigerant oil recovery operation, set the dipswitches 3-1 and

4-8 to ON in that order.

“S-0” “r-0”: The refrigerant oil recovery operation is not completed. To restart the refrigerant oil recovery operation, set the dipswitches 3-1 and

4-8 to ON in that order.

8Disconnecting the cylinder

After completing the oil recovery operation, close the valve on the cylinder, and disconnect the cylinder within five minutes.

9Recording the amount of refrigerant that was charged

Write on the control box panel the amount of refrigerant charged.

0Closing the valve on the connecting port to the refrigerant circuit

Close BV3 completely. The refrigerant oil recovered from the existing pipes is sealed in an oil recovery vessel.
