10-1-3. Refrigerant recovery procedure B (Case of outdoor unit

backup operation setting)

<Outline>

If outdoor unit backup operation setting is performed, use an alternative refrigerant recovery procedure as
described below, provided that the power cannot be turned on for the failed outdoor unit. (Refrigerant will be
recovered from the failed outdoor unit using the test cooling operation function.)

Note 1:

If cooling-season outdoor unit backup operation or outdoor unit backup operation is in progress with the
power supply to the failed outdoor unit turned on, follow the procedure described in “10-1-2. Refrigerant
recovery procedure A (Case of no outdoor unit backup operation setting)”. If outdoor unit backup
operation setting is performed with the power supply to the failed outdoor unit turned on, recovery
operation can only start after putting the outdoor-outdoor communication connector on the interface P.C.
board of that unit [CN03] back to its initial state and resetting the power supply.

Note 2:

If the power cannot be turned on the failed outdoor unit, the solenoid valves and PMVs of the unit cannot
be turned on, so that it reduces the amount of recovered refrigerant compared to a standard pump-down
operation. Recover the residual gas in the unit using a refrigerant recovery device, and be sure to
measure the amount of recovered refrigerant.

<Work procedure>

[Setup of failed outdoor unit]

(1) Connect the liquid pipe check joint and the low pressure-side check joint using a gauge manifold, and purge the

manifold of air (to recover refrigerant from the liquid tank and heat exchangers).

(2) Fully close the liquid pipe packed valve of the failed outdoor unit.

(Leave the service valve of the gas pipe and the packed valve of the balance pipe fully open.)

[Setup of unit selected as header unit (hereafter “header outdoor unit”)]

(3) Set SW01/02/03 on the interface P.C. board of the header outdoor unit to 2/5/1. After [C. ] [… … …] is displayed

on the 7-segment display, press SW04 and hold for 5 seconds or more.

(4) After [C. …] [… – C] is displayed on the 7-segment display, the system starts operating in the test cooling

operation mode.

(5) Set SW01/02/03 on the interface P.C. board of the header outdoor unit to 1/2/2 to have the low-pressure sensor

output (MPa) displayed on the 7-segment display.

(6)

Approx.

after the system starts

up, fully close the gas
