(a) Preparing Manifold Gauge/Hose Set For Use If the manifold gauge/hose set is new or

was exposed to the atmosphere, it will need to be evacuated to remove contaminants

and air as follows:

Back seat (turn counterclockwise) both field service couplings (Figure 3-4) and mid

seat both hand valves.

Connect the yellow hose to a vacuum pump and refrigerant 134a cylinder.

Evacuate to 10 inches of vacuum and then charge with R-134a to a slightly positive

pressure of 1.0 psig @ (0.1 kg/cm).

Front seat both manifold gauge set valves and disconnect from cylinder. The gauge

set is now ready for use.
