Subaru Legacy BN/BS (2015-2019) Service Manual: Refrigerant recovery procedure procedure

Subaru Legacy BN/BS (2015-2019) Service Manual / Hvac system (heater ventilator and a c) / Refrigerant recovery procedure procedure

CAUTION:

• During operation, be sure to wear protective goggles and protective gloves.

• Connect the refrigerant recovery system with the manifold gauge set to discharge the refrigerant from the A/C system and recycle the gas.

• When recycling the discharged refrigerant, keep service cans on hand. Because the recovery rate with the recovery system is approx. 90%, service cans are necessary to charge the refrigerant.

• Follow the detailed operation procedure described in the operation manual attached to the refrigerant recovery system.

(1)	Manifold gauge	(4)	High pressure valve	(7)	High-pressure hose
(2)	Low pressure valve	(5)	Low-pressure hose	(8)	Low-pressure side service port
(3)	Center valve	(6)	Center manifold hose (vacuum pump and charge)	(9)	High-pressure side service port
