DESCRIPTION
REASSEMBLE
Motor
1. Reassemble lower housing assembly (4) to motor.
(Follow steps 4 to 10.)
Diaphragm
2. Lower housing is assembled with:
• Flat side of diaphragm and outer pistons facing
motor
• Hex stem of inner pistons must be aligned into hex
holes in outer pistons (4).
• Outer pistons must be aligned with alignment slots
on cam assembly making sure screw holes align in
cam assembly, otherwise diaphragm will leak.
3. Tighten cam piston screws partially, center piston in
diaphragm, then tighten screws securely (18 in. lbs.
torque)
Lower Housing
4. Reassemble lower housing assembly (4) to motor.
5. Re-tighten set screw securely. Set screw head
must be positioned facing motor covering seam
(indentation). (Positioning of this screw is critical
to avoid misalignment and subsequent diaphragm
damage.)

7. Properly seat O-Ring in check valve assembly (2) and
check if ferrules and screen are in place on upper
housing (1)
8. Install check valve (2) into upper housing (1) and push
