ELECTRICAL HOOK-UP
1. Check that supply voltages match the motor’s requirements.
2. Check motor wiring and connect, according to instructions on motor, to match supply voltage.
3. Power cord should be protected by conduit or by cable and be of proper gauge. It should be no longer than necessary.
4. Power should be drawn directly from a box with circuit breaker protection or with a fused disconnect switch.
We congratulate you on your choice of the EXP Self Priming Pump! It has been carefully designed using the advantages of today’s
technology and carefully constructed to give you the dependability of yesterday. To insure proper performance, we urge you to carefully
follow the instructions in this manual. If you have any questions, call your nearest distributor or EasyPro for assistance.
WARNING: ALWAYS SHUT OFF ELECTRICAL POWER BEFORE INSTALLATION AND / OR SERVICING THIS PUMP!
ALL ELECTRICAL WIRING SHOULD MEET STATE AND LOCAL ORDINANCES. IMPROPER WIRING MAY NOT ONLY BE A
SAFETY HAZARD BUT MAY PERMANENTLY DAMAGE THE MOTOR AND/OR PUMP!
INSTALLATION
Please read carefully! When properly installed this primer pump will provide dependable trouble-free service.
1. Locate pump as near the source to be pumped as possible. A ooded suction situation is preferred. This pump is self-priming, however, there must be
uid in the pump for it to function properly. A check valve is recommended for non-ooded suction. (Figure 2)
2. Mount motor base to a secure, immobile foundation.
3. Use only plastic ttings on both the intake and discharge ports. Seal pipe connections with Teon™ paste. These ttings should be self-supported
and in neutral alignment with each port. (i.e. Fittings must not be forced into alignment which may cause premature line failure or damage to the pump
volute.)
4. Never restrict the intake. Keep both input and discharge lines as free of elbows and valves as possible. Always use pipe of adequate diameter. This will
reduce friction losses and maximize output.
5. This pump must not be run dry! We recommend a ooded suction installation. Please read carefully! When properly installed, the EasyPro pump will
provide dependable, trouble-free service.
6. Before starting pump, the priming pot must be lled with water.

PUMP END ASSEMBLY
1. Clean and inspect all pump parts (0-ring, seal seats, motor shaft, etc.).
2. If replacing the seal, apply sealant in bracket bore hole and around seal case according to sealant instructions. We recommend using Gasgacinch®.
Silicone sealant can also be used.
3. Press seal into bracket while taking care not to damage seal face.
4. Place slinger (rubber washer) over motor shaft and mount bracket to motor.
5. If replacing the seal, carefully lubricate the boot around ceramic piece and press it into the impeller hub making certain that the ceramic is in evenly
- the sealing surface should be parallel with the impeller hub.
6. Apply clean water to the carbon-graphite and seal seat sealing surfaces. Do not use silicon lubricants or grease!
7. Mount bracket to motor face.
8. Thread impeller onto shaft and install o-ring and screw! If required, remove motor end-cap and use a screwdriver on the back of motor shaft to
prevent shaft rotation while tightening. Replace motor end cap.
9. Place diuser over impeller and tighten allen bolts used to hold diuser in place. Note: Be sure diuser is in an upright position. (The word “top”
appears on the diuser as an indicator).
10. Seat O-ring on diuser. Assemble diuser to bracket with two allen screws.
11. Seat O-ring in bracket slot and assemble casing to bracket.
12. Install drain plugs with its O-rings in casing drain holes.
DISASSEMBLY
1. Shut o power to motor before disconnecting any electrical wiring.
2. Close all necessary valves on inlet and discharge lines and drain the pump by removing both drain plugs. The water will drain faster if you loosen the lid.
3. Disassemble bracket-motor assembly from casing by removing the nuts and bolts. (The casing may be left in-line)
4. Unscrew the two allen bolts and remove diuser. Diuser may need to be pried o with a athead screwdriver.
5. Remove screw and O-ring from front side of impeller. Screw is a left-handed thread and loosens in a clockwise direction.
6. Remove cap covering shaft at back of motor. Unscrew the impeller by twisting counter clockwise while holding the shaft with a large screwdriver to
prevent shaft rotation.
7. Remove ceramic piece from impeller (if replacing the seal).
8. Detach bracket from motor. Remove seal from bracket by pressing out from the back (if replacing the seal). Do not dig out from the front!
