(4) Carefully and slowly loosen the flare nut from the coupling on the back of the gage. Use two wrenches,

one to hold the coupling and the other to loosen the flare nut. Allow the small amount of refrigerant that is in the capillary

to escape. Should refrigerant continue to leak out after a few seconds, tighten the flare nut and check to see that the

compressor valve has been properly backseated.

(5)

Remove the flare nut from the coupling and remove the coupling from the gage.

(6)

Remove the three attaching screws and nuts and pull the gage from the panel.

Installation.

(1)

Mount the gage in the panel with the three screws and nuts.

(2)

Install the coupling on the valve and loosely connect the flare nut.

(3) Slightly crack (turn valve stem clockwise) the compressor discharge valve to allow a very slight amount

of refrigerant to escape through the capillary line at the flare nut to clear the capillary of moisture and air.

(4)

Immediately tighten the flare nut.

(5) Again turn the discharge valve stem fully counterclockwise and then turn it one turn clockwise to

"backseat and crack" the valve. Reinstall the protective cap over the valve stem.

(6)

Using a water and soap solution check the newly connected fittings for leaks.

(7)

Close the access doors and connect power.
