PENTAIR Myers TPL15-R5S Grinder Pump Instruction Manual

PENTAIR Myers TPL15-R5S Grinder Pump

Note: When complete packaged system, including fiberglass basin, is supplied from factory all parts are mounted in basin except pump, check valve, and guide plates. Piping and guide plates for pump are shipped in separate package and must be mounted in the field.

CALIFORNIA PROPOSITION 65 WARNING:
This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.

ASSEMBLING PIPING TO PUMP

Attach guide plate and piping to pump as shown in Figure 1. Be sure piping is plumb, then tighten all set screws. Attach lifting chain to lifting eye with clevis supplied. Pump(s) can now be lowered into position with lifting chain. Retain power and control cords
at surface as pump is lowered. When pump(s) is in place, attach cords to connection box. Remove slack from wires so that they will hang vertical without tangling.

MECHANICAL ASSEMBLY

1. Inlet flange must be mounted to basin at depth required to get gravity flow into basin. Bottom of basin must be at least 36″ below inlet pipe. Two inlet flanges are supplied, one for use with 4 inch SDR 35 PVC pipe and one for use with 4 inch SCHEDULE 40 PVC pipe. Inlet flanges are available for either 4 or 6 inch pipe and more than one inlet may be used if desired.
2. Cut hole(s) through fiberglass basin at desired location using the correct size hole saw. For 4 inch inlets use a 5 inch hole, for 6 inch inlets use a 7 inch hole. Select the inlet that matches the type of pipe being used (4 or 6 inch, SDR 35 or SCH. 40). Insert the inlet into the previously cut hole. Chamfer the ends of the plastic pipe for ease of installation. Lubricate pipe with soapy water. Insert pipe through inlet so that the pipe protrudes through the inlet approximately one inch.
3. This unit is equipped with hold-down guides and hold-down pipe. Upper guides hold to rail and hold-down pipe with set screws. The hold-down pipe is necessary to prevent hydraulic pressure from lifting pump from base. The hydraulic pressure keeps the pumps suspended when in operation so there is no side load on the rails and removal is easier when required.

ELECTRICAL ASSEMBLY

1. Adjust level controls on bracket for proper pumping and alarm elevations. Off level control must be set so that pump will turn off when sump level is 1″ to 2″ above bottom of pump.
2. Connect level control and pump power cords to connection box as shown on connection diagram. Make certain that all compression fittings are tight.
3. Install control box.
4. Run wires to control box through conduit and connect to cords coming into connection box. Mark or trace each incoming wire so that it can be connected to proper cord.
5. Do not install sealing compound into fitting until pumps have been run, to be sure all connections are correct.

INSTALLATION

1. The basin is fiberglass, and concrete must be poured over antiflotation ring to prevent basin from floating up. Do not leave basin in unfilled hole without concrete as ground water or rain may float basin up, breaking inlet, discharge and electrical conduit connections.
2. Cubic feet of concrete to be poured around basin to prevent flotation:

BASIN DIA.

| CUBIC FEET OF CONCRETE REQUIRED PER FOOT OF BASIN DEPTH
---|---
24″| 2 cu. ft.
36″| 5 cu. ft.

STARTING SYSTEM

1. Open 1-1/4″ ball valve.

2. Set H-O-A switch on AUTO position and run water into sump until ON level control starts pump. Allow pump to operate until sump level drops, deactivating OFF level control, stopping pump.
   IMPORTANT – OFF level control should be set so that sump level drops to within 1″ to 2″ from bottom of pump before stopping pump.

3. Turn pump switch to OFF and fill sump over alarm control. Red light should flash.

4. Set H-O-A switch to AUTO position. System is now ready for automatic operation.

IN CASE OF TROUBLE, CHECK THE FOLLOWING

Pump will run but not deliver water.
Cause – 1. Probably air lock. Start and stop pump several times using H-O-A switch. If this does not clear air, turn pump to OFF and run more water into sump 6″ to 12″ higher. If air still does not clear, it may be necessary to raise hold-down pipe and lift pump so that lower seal fitting is out of the discharge case to release air.

Be sure shut-off valve is open in discharge line.

Pump seal fitting leaks.

Cause – Probably cut or broken O-ring. Replace if necessary. Trash may be caught in seal flange. Lift pump and open shut-off valve to back flush discharge casting.
On installations where discharge line is not filled it may be necessary to lift pump until seal flange is out of discharge case, then run pump to flush casting.

CAUTION – Never work on pumps or controls unless power is turned off. If pump is remote from control box, disconnect wires to pump(s) to be certain power cannot be turned on when working on pumps. NEVER PUT FINGERS NEAR GRINDER IMPELLER WHEN PUMP CORD IS CONNECTED.
