Gast 2D Series - Manual (Page 2)

MAINTENANCE
Do not attempt to replace the connecting rod or motor bearings.
If after cleaning the unit and/or installing a new valve, the unit still
does not operate properly, contact your representative, or the
factory, or return the pump to an Authorized Service Facilities.
Before attempting repair, determine if the pump has been
exposed to/or contains biological, toxic, or radioactive materials,
so that the repair personnel are not exposed to these items.
Follow these steps to replace the valve:
1) Disconnect pump from electrical power.
WARNING
Always disconnect power source before servicing. Failure to do
so can result in personal injury and/or property damage.
2) Vent all air lines to the pump to remove pressure.
3) Note the direction of the arrows so you can orient the pump
head correctly during reinstallation.
4) Remove the four corner head screws and remove the head,
valve, and valve plate.
5) Clean the pump head and valve plate using water-based
solvents.
6) Ensure the diaphragm is centered in the recessed area of the
bracket with no bends or folds.
7) Place the new valve on the valve plate so that the holes in the
valve fit over the correct pins in the valve plate.
8) Assemble the head by fitting the correct holes in the head
onto the pins in the valve plate.
9) Place the entire head, valve, and valve plate assembly on top
of the bracket, by aligning the four holes and orienting the ports
in your desired position.
10) Torque the head screws to 17 to 21 in-oz. into the body.
CAUTION
Do not over-tighten head screw(s). To do so can risk stripping
the plastic threads.
