(1)
Install manifold gage set (1) low-side hose (4) to
suction (low) side of A/C compressor.
(2)
Install manifold gauge set (1) high-side hose (5) to
discharge (high) side of A/C compressor.
Personal injury or death can result from
inhaling refrigerant. Only vent refrigerant in a
well-ventilated area.
NOTE
Only open manifold gage set valves long
enough to purge air from charging hose.
(3)
Slowly open valves (2) and (3) and purge air from
charging hose (6).
(4)
Connect charging hose (6) to R-134a refrigerant
tank valve (11).
Contact with refrigerant can cause frostbite. Keep hands and face away to prevent personal injury.
Protective goggles must always be worn when refrigerant lines are opened, even if the gauges
indicate the system is empty.
Do not smoke when servicing air conditioners or wherever refrigerant gas may be present. Personal
injury or death can result from inhaling refrigerant through a lit cigarette.
Do not invert the R-134a refrigerant tank while charging the system. Liquid refrigerant entering the
low side of the A/C system will permanently damage the compressor.
(5)
Ensure that the R-134a refrigerant tank (12) stands vertically upwards, to ensure that only refrigerant vapor can be
charged into the A/C system.
(6)
Open refrigerant tank valve (11) on R-134a refrigerant tank (12).
(7)
Start engine (TM 5-2420-230-10).
(8)
