WARNING: PLEASE READ COMPLETELY BEFORE YOU INSTALL OR OPERATE YOUR NEW PUMP!
This is an external “out-of-pond” pump. It is NOT submersible. Protect from rainfall and frost.
Do NOT allow this pump to become submerged. Never run dry. Max. case pressure.- 25 PSI.

Sustainable, Efficient.
INSTALLATION
Please read carefully! When properly installed, the Sequence® 8000 / 10,000 / 12,000 pumps will provide dependable, trouble-free service.
1. Do not submerse the unit in water - it is not a submersible pump. Do not allow the pump to become submerged during transient periods, such
as heavy rain, run-off, etc.
2. Locate the pump as near the water source as possible. We recommend a ooded suction installation. IT MUST NOT BE RUN DRY.
PLEASE READ CAREFULLY: No air intake into the pump.
3. The pump is not self-priming. Therefore, if the water level is below the pump, a non-return valve must be installed below water level. The pump
and inlet line must be primed prior to start up. For non-ooded installations, a strainer basket and check valve are recommended.
4. Mount the motor base to a secure, immobile foundation.
5. Use only plastic ttings on both the inlet and discharge ports. Seal the inlet & discharge ttings with PTFE tape. These ttings should be
self-supported and in neutral alignment with each port (i.e., Fittings must not be forced into port alignment which may cause premature line
failure or damage to the pump volute).
6. Never restrict the inlet! Keep both inlet 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. Never use an inlet line of smaller diameter than the discharge line. Minimize the suction lift.
7. Always protect your pump from rainfall.
ELECTRICAL HOOK-UP
CAREFULLY, EXAMINE THE POWER CORD BEFORE USE. DO NOT USE THIS POWER CORD IF THERE IS ANY VISIBLE DAMAGE. DO NOT USE THIS POWER CORD IN WATER
OR IF THE MOTOR OR ELECTRICAL RECEPTACLE IS IN CONTACT WITH ANY STANDING WATER! THIS POWER CORD SHOULD ONLY BE PLUGGED INTO A PROPERLY
INSTALLED RCD! ALWAYS TEST CYCLE A RCD TO DETERMINE ITS CONDITION BEFORE USE!
We congratulate you on your choice of the Sequence® 8000 / 10,000 / 12,000 centrifugal pump! (Also referred to as the Sequence® 750
pump range). Its leading edge design provides you with high output at a minimal operating cost. It is carefully constructed to give you
long term, reliable service. To insure proper performance, we urge you to carefully follow the instructions in this manual. If you have any
questions, please call your Evolution Aqua Dealer for assistance.

WARNING: ALWAYS SHUT OFF ELECTRICAL POWER BEFORE INSTALLATION AND / OR SERVICING THIS PUMP! ELECTRICAL INSTALLATIONS MUST BE
DONE BY A QUALIFIED ELECTRICIAN. A RESIDUAL CURRENT DEVICE (RCD), ALSO KNOWN AS THE RESIDUAL CURRENT CIRCUIT BREAKER (RCCB),
WITH A TRIPPING CURRENT NOT EXCEEDING 30mA MUST BE INSTALLED IN THE SUPPLY CIRCUIT. A MEANS OF DISCONNECTION FROM THE SUPPLY
HAVING A CONTACT SEPARATION OF AT LEAST 3MM IN ALL POLES MUST BE INCORPORATED IN THE WIRING.

DISASSEMBLY
1 . Shut off power to the motor before servicing any pump!
2. Unplug the power cord.
3. Disassemble the volute from the bracket - six P-Bolts and six anged lock nuts. The volute may remain
attached to the plumbing to help simplify re-installation.
4. Lock the shaft by placing a screwdriver blade into the shaft slot at the fan end of the motor. Unthread the
impeller from the motor shaft - Take care not to misplace the small metal impeller washer.
5. Remove the ceramic, with rubber boot, from the impeller hub (if you are replacing the seal).
6. Loosen the four M-Bolts attaching the bracket to the motor. Rotate the bracket counter-clock wise until
the screw heads are located in the large key hole slots. Lift off the bracket from the motor.
7. Remove the carbon-graphite seal assembly from the bracket by pressing it out from the motor-side of the bracket.
Do not pry it out with a screwdriver from the pump cavity-side of the bracket (if you are replacing the seal)!
PUMP END ASSEMBLY
1 . Inspect all pump parts (O-ring, O-ring groove, impeller hub ID, motor shaft, etc.) and clean if necessary.
2. Apply silicone sealant to the bracket bore ID wall and around the seal case - follow sealant mfg. instructions.
3. Press the carbon graphite seal into the bracket while taking care not to touch or damage the carbon graphite face. Never touch or apply pressure
to the carbon graphite seal face!
4. Screw four M-Bolts ve complete turns into the threaded holes located on the motor face.
5. Mount the bracket to the motor by aligning the key holes over each bolt head, then rotate clockwise which will position the small key hole slot
under each bolt head. Tighten each bolt with a wrench to secure the bracket to the motor (8-25 lb. in.).
6. Carefully, lubricate the seal seat elastomer OD and impeller hub ID with water. Press the seal seat into the impeller hub making certain that the
ceramic is in evenly - the sealing surface should be parallel with the impeller hub.
7. Apply CLEAN water to the carbon-graphite and seal seat sealing surfaces. Do not use silicon lubricants or grease!
8. Lock the shaft by placing a screwdriver blade into the shaft slot at the fan end of the motor. Thread the impeller onto the motor shaft.
Thread until the washer securely contacts the shaft shoulder.
9. Seat the large O-ring into the bracket O-ring groove.
10. Assemble the volute onto the bracket with six P-Bolts (10-24 x 2 3/4” carriage bolts) and six anged lock nuts. Tighten in a cross pattern (30 lb. in.).
11. Install the drain plug and O-ring, into the volute drain hole.
12. Before operating the Sequence® pumps, allow a proper cure time for the sealant used in step 2.
