Hot gas valve (continued)
SETTING
Observing the suction pressure (while the unit is running in the
heat/idle cycle) will indicate the setting of the hot gas valve. The
valve is set correctly when the suction gauge indicates 25 PSIG
for any system using R-22 refrigerant.
The setting is adjusted as shown in the illustrations. Turning the
adjustment clockwise will increase the pressure setting on either
type valve. Contact NESLAB Technical Service for setting
specifications on systems using other refrigerants.
