1. Most accidents can be avoided by using COMMON SENSE.

2. Please read the operation and maintenance instruction manual supplied with the
pump. If you did not receive one, please call your local distributor before pump
installation.

3. Do not wear loose apparel that may become entangled in the impeller or other
moving parts.

4. Always use appropriate safety equipment, such as safety glasses, when working on
the pump or piping.

5. Pumps build up heat and pressure during operation-allow time for pumps to cool
before handling or servicing.

6. Only qualified service personnel should install, operate and repair pump.

7. Keep clear of suction and discharge openings. DO NOT insert fingers in pump with
power connected.

8. Do not pump flammable or hazardous materials (gasoline, acids, alkalis, etc.)

9. Do not block or restrict discharge hose, as it may whip or burst catastrophically
under pressure.

10. Make sure lifting handles/hooks are securely fastened each time before lifting.

11. Do not lift pump by the power cord under any circumstances.

12. Do not exceed manufacturer's recommendation for optimum performance, as this
could cause the motor/pump to overheat and lead to premature wear or failure.

13. Secure the pump in its operating position so it does not tip over, fall or slide.

14. Keep away from impeller when power is connected.

15. Submersible Pumps are not approved for use in swimming pools, recreational water
installations, decorative fountains or any installation where human contact with the
pumped fluid is common.

16. Do not operate pump without adequate protection and safety devices in place.

17. Always replace safety devices that have been removed during service or repair.

18. To reduce risk of electrical shock, pump must be properly grounded in accordance
with the National Electric Code and all applicable state and local codes and
ordinances.

19. To reduce risk of electrical shock, always disconnect the pump from the power

source before handling or servicing.

20. Any wiring of pumps should be performed by a qualified electrician.

21. Never operate a pump with a power cord that has frayed or brittle insulation.

22. Cable should be protected at all times to avoid punctures, cuts, and

abrasions - inspect frequently.

23. Never handle connected - "hot" power cords with wet hands.

24. Never operate a pump with a plug-in type power cord without a ground fault circuit
interrupter, adequate overload and short circuit protection.

IMPORTANT !!! MODY Pumps Inc. is not responsible for losses, injury, or death resulting

INTRODUCTION

THE

“mody” MOTOR DRIVEN PORTABLE SUBMERSIBLE PUMPS HAVE BEEN DEVELOPED DUE TO

A LONG FELT NEED OF HAVING A TRULY MAINTENANCE FREE PUMPSET FOR VARIOUS
APPLICATIONS. THE PUMP IS A LIGHTWEIGHT, COMPACT UNIT ENABLING IT TO BE USED IN
MOST SEA-CRAFT AND DIFFICULT LAND INSTALLATIONS. THE UNIT CONSISTS OF A
VERTICAL CENTRIFUGAL PUMP WITH AN IN-BUILT SQUIRREL CAGE, INDUCTION ELECTRIC
MOTOR WHICH IS AVAILABLE FOR VARIOUS ELECTRIC SUPPLY CONFIGURATIONS. THE PUMPED
WATER IS USED AS A COOLING MEDIUM WHICH COOLS THE ELECTRIC MOTOR. THE PUMPSET
CAN ALSO BE USED IN ANY POSITION THUS MAKING IT IDEAL FOR DEWATERING IN
DIFFICULT LOCATIONS.

THE SERVICE LIFE OF A SUBMERSIBLE PUMP DEPENDS MAINLY ON TWO THINGS: THE
DEPENDABILITY OF THE SEALING SYSTEM AND THE WEAR RESISTANCE OF THE PUMP WEAR
PARTS.

“mody” SUBMERSIBLE SUMP PUMPS INCORPORATE A UNIQUE SEALING SYSTEM. THE

ALL
CONSTRUCTION CONSISTS OF TWO MECHANICAL SEALS, ARRANGED IN TANDEM, IMMERSED IN
AN OIL BATH. THE COMPLETE PACKAGE IS A PRESSURE COMPENSATED SEALING DEVICE
WHICH ENSURES A MINIMAL PRESSURE DIFFERENTIAL ACROSS THE SEAL FACES,
IRRESPECTIVE OF THE DEPTH SETTING OF THE PUMP OR THE HEAD AGAINST WHICH THE
PUMP IS OPERATING.

“mody” SUBMERSIBLE SUMP PUMPS, ALL WEAR PARTS ARE RUBBER LINED/COVERED AND

IN
ARE READILY REPLACEABLE AS NEEDED. BOTH WEAR AND ELECTRICITY CONSUMPTION ARE
STILL FURTHER REDUCED WHEN THE PUMPS ARE FITTED WITH BUILT-IN LEVEL CONTROLS
FOR AUTOMATIC STARTING AND STOPPING. IT IS HOWEVER RECOMMENDED THAT

IRRESPECTIVE OF TYPE OF PUMP, ADEQUATE MOTOR PROTECTION SWITCHGEAR SHOULD BE
USED AT THE INSTALLATION. WE STRONGLY RECOMMEND THE USE OF SUITABLE CONTROL
PANELS WHICH ARE AVAILABLE FROM US INCORPORATING ALL REQUIRED PROTECTION
DEVICES.

IT IS IN THE INTEREST OF THE USER THAT HE GO THROUGH THIS MANUAL IN DETAIL
PRIOR TO USING THE PUMP. THE MANUAL WILL HELP HIM UNDERSTAND THE CONSTRUCTIONAL
FEATURES AND TO OBTAIN TROUBLE FREE SERVICE FROM THE PUMP.

PURPOSE:

THE PUMP HAS BASICALLY BEEN DESIGNED AS A DEWATERING UNIT TO PUMP OUT FLOODED
INSTALLATIONS OR ANY CONDITIONS THAT NEED DEWATERING OF UNWANTED FLUIDS. THE
PUMP HAS BEEN DESIGNED TO HANDLE WATER CONTAMINATED WITH OIL AS WELL AS
ABRASIVE PARTICLES NORMALLY ASSOCIATED WITH RAW WATER. THE MAXIMUM SIZE OF
PARTICLES THAT CAN BE HANDLED IS APPROX. 0.4”. THE MAXIMUM SPECIFIC GRAVITY OF

THE PUMPED FLUID SHOULD NOT EXCEED 1.1.

SAFETY PRECAUTIONS:

1. ENSURE THAT THE INSULATION RESISTANCE OF THE MOTOR IS AT LEAST 1 MEG. OHM
BEFORE ENERGIZING THE UNIT.

2. CHECK THAT THE AVAILABLE POWER SUPPLY (VOLTAGE, PHASE, FREQUENCY) MATCHES
WITH THE DETAILS ON THE PUMP NAMEPLATE.

3. ENSURE THAT THE GROUND WIRE IN THE 4 CORE CABLE SUPPLIED WITH THE PUMP IS
SECURELY EARTHED.

4. ENSURE DISCHARGE CONNECTION IS CORRECTLY AND SECURELY FITTED

5. ENSURE DELIVERY HOSE IS FREE FROM KINKS AND SHARP BENDS.

6. DO NOT LIFT OR PULL THE PUMP UNDER ANY CIRCUMSTANCES BY MEANS OF THE CABLE.
THE PUMP MUST BE LOWERED/LIFTED FROM THE SPACE TO BE PUMPED BY USING A LIFTING
ROPE ATTACHED TO THE HANDLE/EYEBOLT PROVIDED IN THE PUMP.

7. AT THE STARTING MOMENT THE PUMP SHALL MAKE A KICK WHICH IS OPPOSITE TO THE
DIRECTION OF ROTATION OF THE IMPELLER. ENSURE THE KICK IS IN THE CORRECT
DIRECTION (SEE THE ARROW ON THE PUMP). SHIFT ANY TWO PHASES IN THE MALE PLUG IF
THE KICK IS WRONG. SINGLE PHASE UNITS THE DIRECTION OF ROTATION IS PRE-SET AT
THE FACTORY.

8. DRY RUNNING OF THE PUMP IS NOT DESIRABLE. HOWEVER THE PUMP WILL NOT BE
DAMAGED OR SUFFER ANY ILL EFFECTS IF IT IS RUN DRY FOR SHORT PERIODS (UPTO
APPROX. 30 MINUTES).

9. THE MAXIMUM PUMP SUBMERGENCE RECOMMENDED IS 50 FEET.

10. THE MAXIMUM SPECIFIC GRAVITY OF PUMPED FLUID SHOULD NOT EXCEED 1.1.
PUMP IS DESIGNED TO OPERATE IN FLUIDS WITH pH from 5 – 8.

11. IF PUMP IS NOT USED AND LYING IN STORAGE FOR MORE THAN 30 DAYS PLEASE
ENSURE THAT THE SEAL FACES ARE NOT GAUGE LOCKED – ROTATE THE IMPELLER/KICK
START THE UNIT ONCE A MONTH. REFER TO INSTRUCTIONS ON DISASSEMBLY/REASSEMBLY OF
MECH. SEALS IN THE EVENT THE FACES HAVE LOCKED.

12. ENSURE CORRECT OVERLOAD BREAKERS ARE INSTALLED IN POWER CIRCUIT BEFORE
STARTING THE PUMP. (REFER TO AMP RATING ON NAMEPLATE).
