620560 4 Diaphragm Pump

THANK YOU FOR USING OUR PRODUCT!
Please read this instruction carefully before operating and retain the instructions for future reference.
Our Pump retains the raw power and pressure of its predecessors, but also can adapt to situations where huge flow is not needed. Compact but capable, it is a great fit for tight spaces. lt also may be configured with different inlet types, each with their own unique fittings, to be sure that it fits any application you can find.

FEATURES

• 4 chamber diaphragm pump
• Continuous duty
• Bypass: reduces cycling
• Run dry capable for normal workloads
• Automatic: controlled by pressure switch
• lndustry standard mounting pattern
• Self priming
• Quiet Operation
• lgnition protected

APPLICATIONS

• Yacht/RV/caravan pressurized water system
• Sprayer fixtures (vehicle-mounted sprayers, electric sprayers)
• Cleaning machines, humidifier, water purification, medical apparatus
• Food beverage filling & liquid transfer
• Solar water system
• Any other pressurization system

INSTALLATION

Materials

1 diaphragm pump with related accessories
2 (at least) pieces of flexible, reinforced hose piping, with collapsing strength
of twice the inlet collapsing pressure, hose must be minimum ½“
4 stainless steel hose clamps and screws
4 screws to fasten the pump to the mounting surface
1 electrical cutoff switch
1 fuse
1 screwdriver
1 strong cutting implement for tubing
(if desired) Teflon tape or sealant

Setup

1. The pump may be mounted in any position. If mounted vertically, the pump head should be in the down position to avoid leakage into the motor casing in the event of a malfunction.
2. Secure the feet, but do not compress them. Overtightening the securing screws may reduce their ability to dissipate noise and vibration.
3. Intake hose must be minimum 1/2″ (13 mm) reinforced hose. Main distribution line from pump outlet should also be 1/2″ (13mm) with branch and individual supply lines to outlets no smaller than 3/8″ (10 mm).
4. Plumb the system using high pressure (2 x pump rating), braided, flexible tubing to minimize vibration/noise.
5. Do not apply inlet pressure in excess of 30psi. In general, try to avoid any inlet pressure completely.
6. Avoid any kinks or fittings which could cause excessive restrictions.
7. Strainer should be attached to the inlet side.
8. The fittings must be secured to avoid leakage.
9. Use clamps at both ends of hose to prevent air leaks into the water line.
10. If a check valve is installed in the plumbing, it must have a cracking pressure of no more than 2 psi.
11. If applying a sealer or plumbing tape, be careful to not overtighten, as they may be sucked into pump.
12. This pump should be wired on its own dedicated circuit. Connect the positive lead (red) to the positive terminal of your battery and the negative wire (black) to the negative terminal of your battery.
13. In an easily accessible location, install a switch to control electricity to the pump. Turn the pump off when not used for extended periods or when the tank is empty.
14. The electrical circuit should be protected with an over-current protection device (fuse) in the positive lead. This pump requires a 15 amp fuse.
15. The pump circuit should not include any other electrical loads.
16.  As the water supply pump is non-essential, reference the wire Chart under the electrical information.Be sure to have the correct wire sizing for the length of wire you are using.
17. After installation, check the voltage at the pump motor.Voltage should be checked when pump is operating. Full voltage must be available at the pump motor at all times.

Notes

1. Flexible potable water hose or PEX tubing is recommended instead of rigid piping at pump. If you choose to use rigid piping, provide a short length of hose between pipe and the pump to avoid noise and vibration.
2. We do not recommend the use of metal fittings. When possible, use the provided plastic fittings.
3. Do not adjust the bypass personally without the help of technician.
4. Lack of sanitizing and maintenance is one of the main reasons of under performance of the pump. Please do maintenance and winterize 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.

WARRANTY

The warranty period is 36 months. Reimo reserves the right to rectify eventual defaults. The guarantee is excluded for all damages caused by faulty use or improper handling. Liability limitations: In no case Reimo will be reliable for collateral-, secondary- or indirect damages, costs, expenditure, missed benefits or missed earnings. The indicated sales price of the product is representing the equivalent value of Reimo’s liability limitations.

REPAIR KITS

TROUBLESHOOTING

Pulsating flow­pump 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 leaks.

Noisy

• Check if the mounting feet are compressed too tightly.
• Is the mounting surface flexible? lf so, it may be adding noise.
• Check for loose head/screws.
• lf the pump is plumbed with rigid pipe, then it may transmit noise more easily.

Failure to prime but motor operates­no 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.
• lnsufficient 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.

USE THE FOLLOWING PROCESS TO ADJUST SHUT­OFF
AND BY­PASS PRESSURES
lnstall the pump as the following picture

• Remove the pressure adjustment screw completely, mark the screw in relation to the switch housing for reference as to number of »turns«, start screwing the set screw clockwise »9 to 9½ turns«, as the c. This will increase the pressure to shut-off at approximately 60 psi.

• Remove the by-pass adjustment screw completely, mark the screw in relation to the by-pass housing for reference as to number of »turns«, start screwing the set screw clockwise »10½ to 11 turns« as the c. This will increase the maximum bypass pressure to approximately 67 psi.
  How to verity the shut­off and by­pass pressures?

• After adjustment the screw, slowly close the valve until shutout. The pressure gauge pointer jitter instantaneous data is shut-off/by-pass pressure.
