[1] HANDLING OF SERVICE TOOLS
(1) Manifold Gauge Set
The hand valves on the manifold gauge set are used to open
and close the valve. The hand valve inscribed LO is for the low
pressure side valve (3) and HI is for the high pressure side valve (4).
By opening or closing the high and low pressure hand valves, the
following circuits are established.
9Y1210003CAS0006US0
When LO Pressure Side Valve and HI Pressure Side Valve are
Closed
Two circuits are established.
Port (
C ) → LO pressure gauge (1)
Port ( A ) → HI pressure gauge (2)
NOTE
• Schrader valve (D) must be opened.
9Y1210003CAS0007US0
When LO Valve is Opened and HI Valve is Closed
Two circuits are established.
Port (
C ) → LO pressure gauge (1)
→ Port ( B )
→ Port ( D )
Port ( A ) → HI pressure gauge (2)
NOTE
• Schrader valve (D) must be opened.
9Y1210003CAS0008US0
When LO Valve is Closed and HI Valve is Opened
Two circuits are established.
Port (
C ) → HI pressure gauge (2)
→ Port ( B )
→ Port ( D ) (Schrader valve must be opened)
Port ( A ) → LO pressure gauge (1)
NOTE
• Schrader valve (D) must be opened.
