INSTALLATION

Pump Location

Install the pump in a clean, dry, and ventilated location that provides adequate drainage, room for servicing, and protection from freezing temperatures.

Bolt down the pump evenly on a good foundation, preferably concrete, to prevent the development of unnecessary stress. Locate the pump as close as possible to the water supply to reduce friction losses in the suction pipe and to provide for maximum capacities. A foot valve must be used.

Suction Pipe

Use only new, clean pipe or hose the same size as that of the pump suction tapping. If the pump is installed any appreciable distance away from the water supply, increase the suction pipe by one size. The suction pipe must always slope upwards from the water source to the pump to avoid air pockets in the line. It is advisable to use a 90° or 45° elbow on the suction line. This enables the pump to prime sooner and also prevents kinking of the hose. A check valve is recommended to ensure easier priming. In cases where a maximum volume of water is required over a prolonged period, the suction line should be led almost horizontally to the pump. Use non-toxic thread compound on all pipe joints, and tighten all connections thoroughly. Connect a strainer to the bottom end of the suction pipe and ensure that it is well submerged at all times.

Grounding the Motor

Wiring to this pump must be installed and maintained in accordance with the National Electrical Code or your local electric code. If more information is needed, call your local licensed electrician or your power company.

It is recommended that a permanent ground connection be made to the unit using a conductor of appropriate size from a metal underground water pipe or a grounded lead in the service panel. Do not ground to a gas supply line. Do not connect to electric power supply until unit is permanently grounded. Connect the ground wire to the approved ground and then connect to the terminal provided.

WARNING RISK OF ELECTRICAL SHOCK

Wiring: Make sure the voltage and frequency of the power supply agrees with the voltage of the pump. If in doubt, check with the power company. Connect wiring to terminal board located inside motor terminal box cover.

Single Shallow Well (Figure 4)

The single shallow well (Figure 4) is typically a drilled well with a 4" or 6" steel or plastic casing running vertically into the ground. The surface of the water should not exceed 25 feet in depth. Connect the foot valve to the first length of suction pipe and lower into well. Add pipe sections as needed, securing them using one of the sealing methods previously mentioned. The foot valve should be AT LEAST 5 feet below the surface of the water to allow for water draw down. Seal the top of the 4" or 6" well casing with a well seal to prevent debris from falling into the well.

A. Suction Port Connection (Figure 5)

1. Attach the foot valve or well point to pipe assembly and lower pipe and foot valve until it is at least five feet below the water level. If you are using a well, temporarily clamp the pipe to the well casing to prevent the pipe from sliding into the well. If well is in a 4" or 6" casing, use a well seal at the surface. Never use a suction pipe size smaller than the size of the suction port on the pump.

2. Connect the necessary elbows, fittings, check valves, and pipe from the water to the pump suction port on front of pump. When using PVC, pre-assemble pipe and fittings to the pump BEFORE applying PVC cement to ensure proper cuts and inventory. Use PTFE tape on all male threads, wrapping clockwise (when facing pipe) 1 to 2 layers thick. Tighten all threaded pipe fittings until snug. DO NOT OVER-TIGHTEN PIPE AND FITTINGS. Tighten joints hand-tight plus 1/2 turn with pipe wrench.

B. Discharge Port Connections (Figure 6)

1. Thread male adapter or pipe nipple into discharge port on top of pump. (Use PTFE tape on thread.)

2. Connect pipe between the sprinkler manifold and the pump discharge. Discharge pipe size should increase with long pipe runs. Discharge pipe size may equal discharge port size for distances up to 100'. Increase discharge pipe size by one size for distances of 100' to 300'. For 300' to 600', increase pipe size by two sizes. This will reduce pressure loss caused by friction.

3. Tighten all threaded pipe connections with pipe wrench until snug. Do not over-tighten.

OPERATION

A priming port plug is provided in the top of the casing to fill the pump with water. Once filled and the priming plug replaced, the pump will prime. The priming time depends upon the vertical and horizontal distance between the pump and the water level.

Remove priming port plug from pump (Figure 7). Open discharge valves and any hoses on discharge side of pump. Fill pump with water through the priming port on top of pump. Allow trapped air to escape for a few minutes, then add more water until full Replace priming port plug and tighten with wrench, using PTFE tape on pipe threads. Start the pump. A properly primed pump should discharge water without air at a consistent pressure. If the pump does not produce water after five minutes, stop the pump, release all pressure, remove priming port plug, add more water, replace plug, and try again. Ensure that a foot valve is properly installed on the suction pipe (Figure 5). If an exceptionally long suction line is used, the water in the pump casing may become overheated or vapourlocked. Should this occur, replace the water in the casing with cold water and continue priming.

MAINTENANCE

WARNING ELECTRICAL PRECAUTIONS

All wiring, electrical connections, and system grounding must comply with the National Electrical Code (NEC) and with any local codes and ordinances. Employ a licensed electrician.

WARNING RISK OF ELECTRICAL SHOCK

• Have an electrician provide electrical power to the motor.

• Motor must be grounded and terminal cover in place to reduce electrical shock hazard.

• Keep motor operating area as dry as possible.

• A ground fault circuit interrupter (GCFI) protected circuit is recommended for use with any electrical device operating near water.

• Always disconnect power before servicing.

• Not investigated for use in swimming pool areas.

Lubrication: The pump requires no lubrication.

Draining

Should the pump be subject to freezing temperatures, it will be necessary to drain the pump completely. To drain, remove the drain plug located at the bottom of the front face of the pump casing and the priming plug and make sure that the drain hole is not restricted. After all the water has been drained, operating the pump for a few seconds will ensure that the impeller is devoid of water (make sure that the suction line is also devoid of water).

Pump Storage

Drain liquid from pump to prevent freezing. It is recommended that a good rust inhibitor be put in the liquid end to prevent excessive corrosion. Be sure motor is kept dry and covered. When restoring the use of the pump, replace all plugs and make sure all connections are tightly sealed. After a complete check is made, make the initial prime according to the OPERATION section.

Disassembly

1. Shut off the power to the pump at the main service panel and disconnect the power supply from motor.

2. Open a tap in the water system to release the pressure.

3. Remove the drain and fill plugs (8, 10) to allow the pump to drain.

4. Remove the four bolts (9), the casing (11), the gasket (12) and O-ring (6).

5. Remove the screws on the diffuser (7) to separate the diffuser (13) from the motor adapter (3). Remove the cap (16) and insert a screwdriver to prevent the shaft from turning while unscrewing the impeller (5). If impeller cannot be turned by hand, insert a flat object into the impeller vane.

NOTE: Use a strap wrench on the impeller eye to remove the impeller.

6. Slip the rotating seal (4) off the impeller hub.

7. To replace the seal seat (4A) remove four bolts to remove the case adapter (3) to separate from the motor (2). Push the seal seat (4A) out of the case adapter from the motor side.

Reassembly

1. Clean all the parts thoroughly before assembling.

2. Lightly lubricate (with soapy water) the rubber cap on the ceramic seal (4) and push it into the adapter (3) using your thumbs only. Make sure the smooth surface of the ceramic seat faces outwards

NOTE: If the pump will remain out of service for longer than one week, the seal components must be installed dry (no lubrication).

3. Put the adapter back on the motor with the four bolts removed previously.

4. Lubricate the rotating seal (4) (with soapy water) and slip it onto the impeller hub with the ‘carbon’ ring towards the ceramic seat. Apply thread locker to shaft threads prior to installing impeller.

5. Replace the impeller (5) and the diffuser (13).

6. Replace the casing (11) making sure that the gasket (12) and O-ring (6) are not damaged and is in place.

7. Reconnect the tubes to the casing and to the pressure switch.

8. Reconnect the power.

9. Prime pump, start the pump and check for leaks.
