CONVERTING AN EXISTING PUMP TO A DEGASSING HEAD
1. Disconnect the suction, discharge and return tubing (if applicable) from the existing pump
head.
2. Remove the four head screws / washers from the pump head. Remove the head assembly
from the pump.
3. Place the degassing pump head assembly on the pump with the head arrow pointing up.
4. Reinstall the four head screw / washers. Tighten the screws evenly in a crisscross pattern
until they are hand tight (18-22 in/lbs (8-10kg)).
NOTE: Although not included, bleed valve may still be used on discharge valve for convenient
manual pressure relief and drain of discharge line.
PRIMING THE PUMP
1. Turn on the power to the pump.
2. Adjust the stroke length to 100%.
3. At this point, the pump will automatically purge the air from the pump head via the degas
valve. Once the fluid starts pumping out of the discharge line, re-adjust the pump flow to the
desired rate.
