MANIFOLD OPERATING INSTRUCTIONS
ATD-3692
R134A ALUMINIUM MANIFOLD GAUGE
SET
WARNING:
Always wear safety goggles when working with
refrigerants. Contact with refrigerant can cause eye injury.
Disconnect hoses with extreme caution! Pressurized
refrigerant may be present in hoses. Always point hoses away
from you and anyone nearby.
Your manifold is designed so that all three lower fittings are connected to each other by
internal passages. Separate passages from the low and high side fittings to their
respective gauges give you pressure and vacuum readings whether the handwheels are
open or closed. For your convenience and safety, handwheels and gauges are
color-coded with the blue compound gauge on the left or low side, and the red pressure
gauge on the high or right side.
Diagnosing System Operation
1. Connect the blue low side hose to the A/C system’s low side service port. Connect the
red high side hose to the A/C system’s high side service port.
2. With the manifold handwheels closed, read the pressure on the gauge face.
3. Use the temperature/pressure chart in the back of this manual to find the
corresponding temperature for the refrigerant in the system.
4. Compare these pressure and temperatures to the A/C system manufacturer’s
specifications for proper operation.
5. If the system is within the correct operating guidelines, disconnect the manifold hoses
from the system. If repairs are necessary, follow the steps for recovering, evacuating
and recharging the system.
