For“Risk of electrical shock” Do not remove power supply cord andstrain relief or connect conduit directly to the pump.Installation and checking of electrical circuits and hardware shouldbe performed by a qualified licensed electrician.To automatically operate a non-automatic three phase pump, a control panel isrequired. UFollow the instructions provided with the panel to wire the system. Uautomatic three phase pumps see automatic three phase wiring diagram.Before installing a pump, check the pump rotation to insure that wiring has beenconnected properly to power source, and that the green lead of power cord (See wiringdiagram), is connected to a valid ground, momentarily energize the pump, observing thedirections of kick back due to starting torque. Rotation is correct if kick back is in theopposite direction of rotation arrow on the pump casing. If rotation is not correct,switching of any two power leads other than ground will provide the proper rotation.Three phase pumps have integral motor overload protection. It is recommended that allthree phase pumps using a motor starting device also incorporate motor overloadprotection. Pumps must be installed in accordance with the National Electrical Codeand all applicable local codes and ordinances. Pumps are not to be installed in locationsclassified as hazardous in accordance with National Electrical Code, ANSI/NFPA 70.Connect pump to a junction box, outlet box, control box, enclosure with a wiringcompartment that meets NEC and local electrical codes. The provision for supplyconnection shall reduce the risk of water entry during temporary, limited submersionand shall comply with the applicable requirements of the Standard for Enclosures forElectrical Equipment, UL 50, or the standard for Metallic Outlet Boxes, UL 514A, andthe standard for Motor-Operated Water Pumps. UL 778.TROUBLE SHOOTINGDisconnect the power source to the pump BEFORE attemptingany type of trouble shooting, service or repair.PUMP WILL NOT RUN1. Check power supply (fuses, breaker).Reset power.2. Blocked impeller. Remove strainer,check and clean.3. Defective cable or incorrect wiring.4. Strainer clogged. Check and clean asnecessary.5. Float switch tangled/obstructed.Clean and free float switch fromobstruction.6. Float switch defective. Replace floatswitch.7. Pump overheated or temperature ofliquid exceeds pump operatingtemperature.14
UWarning: Pump will restart automatically when motor over-heat protection switchcools.PUMP RUNS BUT DOES NOT DELIVER RATED CAPACITY1. Discharge line clogged, restricted orhose kinked. Check dischargehose/pipe.2. Worn impeller and/or suction cover.Inspect and replace as necessary.3. Pump overloaded due to liquid pumpedbeing too thick.4. Pumping air. Check liquid level andposition of pump.5. Excessive voltage drops due to longcables.6. Three phase only; pump runningbackwards, check rotation.SERVICING YOUR SUBMERSIBLE PUMPPump should be disconnected from the electric power supply before proceeding to doany service or maintenance.To service or repair your pump, please contact your local BJM Pumps distributor.Service should only be performed by a qualified electrician.MAINTAINING YOUR PUMPPump should be disconnected from the electric power supply before proceeding todo any service or maintenance.Pump should be inspected at regular intervals.More frequent inspections are required if the pump is used in a harsh environment.Preventative maintenance should be performed to reduce the chance of prematurefailure.Worn impellers and lip seals should be replaced.Cut or cracked power cords must be replaced. (Never operate a pump with a cut,cracked or damaged power cord.)Seal oil should be checked once per year.Maintenance should always be done when taking a pump out of service beforestorage.1) Clean pump of dirt and other build up.2) Check condition of oil around the shaft seals.3) Check hydraulic parts: check for wear.4) Inspect power cable. Make sure that it is free of nicks or cuts.CHANGING SEAL OILChanging the seal oil in the J & JX Series pumps is very easy.1) Make sure that the pump cable isdisconnected from the power source.2) Lay the pump down on its side.3) Remove the screws that hold thebottom plate in place.4) Remove bottom plate.5) Remove screws holding the suctioncover.6) Remove the suction cover.7) Remove the impeller.5
