Your “Quad II” pump is designed to self-prime up to 6
feet suction lift (vertical distance from shower pan to
pump inlet). This pump is quiet running. It is
recommended you utilize a “lighted” on-off switch
so that the pump is turned off when not in use. the
“Quad II” is able to run dry (no liquid) for extended
periods with no damage to the pump. However, this
could cause needless battery drain.

STEP I
Remove shipping plugs from Quad pump ports. Some
water from factory testing may spill out
STEP 2
Install inlet A and discharge, B port connectors. Firmly
push slide clips C forward to lock port connectors in
place.
STEP 3
Slide rubber mounts fully into 4 mounting tracks.
STEP 4
Mount pump vertically, with pump head down or
horizontally in an ible location. If mounting vertically,
motor up, attach motor mounts first then pump head
mounts, while supporting weight of pump.
STEP 5
Use 1/2” I.D. flexible hose (preferably braided or
reinforced). Use hose clamps on the slip-on barb hose
connectors.
STEP 6
Install a 1/2” in line strainer #01740-002 in accessible
location between shower drain pan and pump inlet. This
strainer or equivalent is required for pump warranty to be
valid.
INSTALLATION
STEP I
Use 14 gauge stranded wire to 20’, 12 gauge to 50’,
from power source.
STEP 2
Use a 10-15 amp rated (lighted) on-off switch on the (+)
positive (red) motor lead.
STEP 3
Install 10 amp fuse protection on the positive lead for the
-143 model, use a 7 amp fuse for the -343 model.
WIRING

DISASSEMBLE
Upper Housing
1. Loosen but do not remove four pump head screws and
carefully remove upper housing assembly (1)
2. Inspect check valve (2) for debris
3. Reassemble new upper housing (1)
Check Valve Assembly
Follow step 1
3. Replace check valve (2)
4. Reassemble upper housing (1)
Lower Housing, Diaphragm, Motor
Follow step 1, then slide rubber foot from mounting track.
3. Rotate kmw housing (4) so mounting notch opening on lower
housing exposes set screw which holds bearing housing to
shaft
4. Loosen this set screw by inserting wrench 1/8” Allen wrench
into mounting notch opening. Then, slide lower housing (4) off
motor shaft.
Diaphragm Cont’d
5. Loosen four cam piston screws with Philfips head screw
driver and pull apart cam from inner pistons. (Pistons should
always be replaced when a new diaphragm is installed.)
Motor Cont’d
5. Replace Motor (5)
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, Dien tighten screws securely (18 in. lbs. torque)
Lower Housing
4. Reassemble lower housing assembly (4) to motor.
5. Retighten 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.)
Upper Housing, Check Valve
6. Reassemble upper housing (1)
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 in.
9. Assemble on to lower housing (4), align 4 screws on to motor
by rotating lower housing (4) if necessary to align feet
10. Tighten screws evenly to 30 in. lbs. torque.
TROUBLESHOOTING
WARNING: BEFORE SERVICING PUMP, TURN OFF PUMP AND DRAIN WATER FROM SYSTEM!!
Failure to Prime - Motor operates, but no pump discharge
• Restricted intake or discharge line
• Air leak in intake line
• Debris in pump
• Punctured pump diaphragm (pump leaks)
• Crack in pump housing
Motor falls to turn on
• Blown fuse
•Loose wiring connection
• Pump circuit has no power
• Defective motor
Low Flow and Pressure
• Air leak at pump intake
• Accumulation of debris inside pump and plumbing
• Worn pump bearing (excessive noise)
• Punctured pump diaphragm (pump leaks)
• Defective motor
Pulsating Flow
