• Hand tighten when connecting the charging hose to the canister's tap valve. Do not use pliers to tighten
the charging hose.
• Store refrigerant containers in a cool, dark place and never leave them in direct sunlight or in a hot place.
• R134a compressor oil readily absorbs moisture, so always seal any parts after disconnecting them.
• Do not use any of the old style R12 refrigerant or previous kinds of refrigerant compressor oil.
The manifold gauge set has a valve handle for opening and
closing valves. The valve handle marked LO is for use on the
low-pressure valve (5) and the valve handle marked HI is for use on
the high-pressure valve (3). The following circuits can be achieved
by variously opening and closing the high and low pressure valves.
(1) Low-Pressure Gauge
(2) High-Pressure Gauge
(3) High-Pressure Valve
When low and high pressure valves are closed
The following 2 circuits are formed.
Port (C) → Low-pressure gauge (1)
Port (A) → High-pressure gauge (2)
CAUTION
• Be sure to open the valve core (d).
(1) Low-Pressure Gauge
With the low-pressure valve open and the high-pressure valve
closed
The following circuits are formed.
Port (C) → Low-pressure gauge (1)
Port (C) → Port (B)
Port (C) → Port (D)
Port (A) → High-pressure gauge (2)
CAUTION
• Be sure to open the valve core (D).
(1) Low-Pressure Gauge
With the low-pressure valve closed and the high-pressure
valve open
The following circuits are formed.
Port (C) → Low-pressure gauge (1)
Port (A) → Port (B)
Port (A) → Port (D) (Be sure to open the valve core.)
Port (A) → High-pressure gauge (2)
CAUTION
• Be sure to open the valve core (D).
