To prevent SERIOUS INJURY
and DEATH:
1. Wear ANSI-approved safety goggles
and heavy-duty work gloves
during setup and use.
2. DO NOT OPEN either
Manifold Valve unless directed to
do so; otherwise, refrigerant leaks,
A/C system contamination,
and hazardous expulsion of
pressurized refrigerant may occur.
3. Use in well-ventilated area only.
4. Keep gauge and hoses away
from moving engine parts.
5. Turn off vehicle’s engine and
A/C system before attaching gauge.
6. The following procedure is to be
performed only by a technician
certified in refrigerant recovery
and recycling procedures,
as explained previously.
Diagnostic Check
1.
Close both Manifold Valves (5,6) by turning CW.
Close both Coupler Valves (7,8) by turning CCW.
2.
CONNECT HOSES:
a. Connect one end of the Blue Hose (13c)
to the Blue LP Hose Connector and the
other end to the Blue Coupler (8).
b. Connect one end of the Red Hose (13a)
to the Red LP Hose Connector and the
other end to the Red Coupler (7).
c. Connect one end of the Yellow Hose (13b) to
the Yellow Charge Hose Connector (10) and the
other end to the Charge Valve on that Connector.
3.
ATTACH COUPLERS:
a. Attach the Blue Coupler (8) to the
suction LP port on the A/C system.
b. Attach the Red Coupler (7) to the
discharge HP port on the A/C system.
4.
PERFORM CHECK:
a. To do a dynamic check:
Turn on the vehicle and allow it to
reach normal operating temperature.
Then, turn on the A/C system.
b. Open both Coupler Valves (7,8) by turning CW.
c. Read the pressure on both of
the Gauges (2,3) and compare
to the manufacturer’s
recommended readings.
5.
AFTER:
a.
Close both Coupler Valves (7,8)
by turning CCW.
b. Turn off the vehicle and the A/C system
if dynamic check was done.
c.
Carefully disconnect the Couplers (7,8),
the hoses may contain residual refrigerant.
Pull back the knurled ring on each Coupler (7,8)
