Installation
Materials
1 diaphragm pump with relied accessories
2 (at neat) process of Sable, reinforced hose piping, with collapsing strength
of tecta the mile collapsing pressure, hose rust be minim 1/2″ 10(42 series)
or 3/4° 10/43 series)
4 starts sled! hose Clamps and screws
4 screws to fasten the pup to the mounting surface
1 electrical atoll patch
1 fuse
4 screw drawer
1 sang citing implement for tubing
(if Greeted) Teflon tape or nescient
Steep
- The pume may be mounted in any position internally out of the weather, if mounted vertically the brume head should be in the down peskier to avoid leakage into the motor casing In ihe event of 2 malfunction.
- Secure tie feet wih screws end washers, bul do nol compress them. Overtightening the securing Screws may reduce True levity 10 Gesipete nobles end vegan.
- Intake Howe must be rename 1/2″ (13 mm) ID (42 series) or 34° (19 mm) ID (43 series) reinforced hose Men disirxton in from pump outie should ate be 1/2″ (13mm) ID (42 series) or 1/2″ (13 mm) to (43 berries) with branch end individual supply in to ovotestes no emailer hen 3/8″ (10 mm),
- Plumb the system using pressure (2 pump rating), braided, exile tubing to minimize vibration/raise.
- Do not apply inlet pressure in excess of 3O0psi. In general, Up to void any inlet pressure completely.
- Avoid any kinks or fittings which could cause excessive resuscitations.
- Strainer to be attached to the inlet side of the pump,
- The fittings must be secured to avoid leakage.
- Use amps at both ends of hose to prevent air leeks into the water line.
- if 9 check valve is installed in the plumbing. it must have s cracking pressure of no more than 2 psl
- (f applying a sealer or plumbing tape, be careful to not overtighten, a6 they may be sucked info pump.
- This puma is to he wired on item own dedicated circuit. Connect the positive lead (red) to the positive terrene of your battery and the negative wire (back) to the negative terminal of your battery.
- In an easily accessible location, install a switch lo control electricity to the pump Tum the pump off when not used for extended periods or when the tank is empty.
- . The electrical cercal should be protected with an over-current protection device (fuse) in the positive lead. This pump requires @ 10 amp fuse.
- The pump arci should not include any other electrical loads.’
- As the water supply pump is non-essential, reference the vary Chart under the lectical information. Be sure to have the correct wire sizing for the length of wire you are using.
- After installation, check the voltage a the pump motor, Voltage should be checked when pump is operating. Full voltage must be available at the pump motor at all limes.
Note
- Flexible potable water hose Is recommended instead of rigid piping at the pump,
- We do not recommend the use of metal fittings. When possible, use the provided plabic fittings.
- 00 not adjust the pressure switch and bypass personally without the help of technician.
- Lack of sanitizing end maintenance Is one of the main reasons of under performance of the pump. Please do maintenance and intense the pump at appropriate times. especially before and after a period of storage.
About the Bypass
Please consult a professional technician In the case that the bypass needs
adjustment. improper adjustment of the bypass may damage the pump.
The bypass comes preset for optimal operation of the pump. If your application
calls for a Different setting for the bypass, you may change it yourself,
Carefully tighten the screw to increase Or loosen the screw to decrease the
minimum operational pressure of the bypass.
Caution
Please do follow the instruction manual to install the product. Any action
outside what is recommended in this manual may bring damage to the pump. Any
inappropriate installation or operation that causes the pump damage is not
covered by warranty.

Troubleshooting
PULSATING FLOW— PUMP CYCLES ON AND OFF
- Check lines for kinks.
- Plumbing lines or fittings may be too small,
- Clean faucets and filters.
- Check fitting tightness for air teaks.
NOISY
- Check if the mounting feet are compressed toa tighily. .
- Is the mounting surface flexible? {f so, it may be adding noise.
- Check for loose head/screws.
- The pump is plumbed with rigid pipe, then it may transmit noise more easily.
FAILURE TO PRIME BUT MOTOR OPERATES – NO PUMP DISCHARGE
- Restricted intake or discharge line.
- Air leak in intake line.
- Punctured pump diaphragm.
- initial amp supply is not enough to sufficiently start the motor.
- Debris clogged in the valves.
- Crack in pump housing.
MOTOR FAILS TO TURN ON
- Loose or improper wiring.
- Pump circuit has no power.
- Blown fuse or thermal protection tripped.
- Failed pressure switch.
- Defective motor.
PUMP FAILS TO TURN OFF AFTER ALL FIXTURES ARE CLOSED
- Punctured diaphragm. ”
- Discharge line leak.
- Defective pressure switch.
- insufficient voltage. ~
- Clogged valves in pump head.
LOW FLOW AND PRESSURE
- Air leak at pump intake.
- Accumulation of debris inside pump or plumbing.
- Worn pump bearing (possibly accompanied by loud noise).
- Punctured diaphragm.
- Defective motor.
