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.
PACKAGE INCLUDES
- 1-1/2″ plastic ball shut-off valve and handle
- 1-1/2″ plastic check valve
- Poly junction box with cord grips
- ALC level control switch
- Alarm switch
- Plastic fittings and length of 1-1/2″ plastic pipe
- Plastic adapter for 1-1/4″ and 1-1/2″ NPT thread to 1- 1/2″ solvent weld pipe
- Plastic rope
- 48″ deep tank with inlet holes around bottom, 18″ riser with 1-1/2″ hub for power and 1-1/2″ hub for pump discharge (threaded)
- Fiberglass cover with locking holes
BASIN INSTALLATION
-
A. Remove basin unit from carton.
-
B. Remove parts package from inside basin.
-
C. Remove shipping restraints from orange alarm switch.
-
D. Check to make sure basin assembly will fit into tank and rest on first shoulder (requires 18-1/2″ dia. round hole). If the hole is square, an adapter plate may be required.
Adapter plate will cover a hole as large as 24″. The plate should be caulked or cemented to top of tank so a water-tight seal is obtained. For additional security, holes may be drilled around the edge of the plate and lag bolted to top of tank. -
E. After it has been determined that the tank fits properly into the access hole and that the tank flange arrangement leaves no holes for infiltration, build up an approximately 1″ thick ridge of mortar or caulking around the lip of the access hole.
-
F. Set the basin into the hole making sure that the mortar seals all the way around the basin flange. Care should be taken to make sure discharge flange is pointed in proper direction.
PUMP INSTALLATION
- A. Remove threaded flanged end from valve assembly. Be careful not to drop square sealing ring out of flange. Screw threaded end of flange onto discharge pipe nipple.
- B. The 1-1/2″ plastic discharge pipe must be cut to length and cemented into the check valve and properly sized adapter depending on the type of pump you are using. This dimension is important and should be measured accurately and have a relatively square cut on the end. After the pipe is cut, screw the adapter into the pump discharge case, slip the pipe into the socket and slip the valve assembly over the top of the pipe.
1-1/2″ DISCHARGE PIPE LENGTH

DISCHARGE ADAPTER
| CUT 1-1/2″ PIPE LENGTH TO
S25| 1-1/2″| 42″
S4| 1-1/2″| 42″
WHRE| 2″*| 38-1/2″
*This adapter does not come with package, but may be ordered separately.
Measure from the bottom of the pump to the bottom of the valve. This dimension
should be the same as from the bottom of the basin to the bottom of the flange
on the discharge pipe.
If the pipe is a little short, it can be lengthened slightly when the pipes
are cemented together
(make sure there is enough contact inside solvent weld sleeve to secure pipe).
If the pipe is too long, it may have to be cut off.
- C. The pipes are now ready to cement. Make sure that the pipes are positioned in correlation to pump.
- D. Use a good grade PVC cement. All parts should be clean. Apply a liberal coat of cement on both parts to be mated. Assemble parts and make 1/4 twist. Make sure parts are aligned before cement sets up.
- E. After the cement has set up, fasten the nylon rope to the top of the pump and carefully lower the pump into the tube using the rope to bear the weight of the pump.
- F. Fasten the valve coupling to the valve flange that has been installed on discharge nipple. (Make sure the square sealing gasket has been installed in the flange.) The flange face should line up with the discharge without bending or straining the parts. Secure the top end of the nylon rope by tying around the discharge pipe.
- G. Remove top of junction box by removing 4 screws. Cut off power cord on pump approximately 1′ longer than the top of the basin (pull pump cordso it extends 1′ outside of basin and cut off). Strip outside jacket so about 8″ of single insulated wire is showing. Run power cord through the empty cord grip in the junction box so that the outer cord jacket shows inside the junction box and tighten the cord grip around the cable jacket.
CONNECTING LEVEL CONTROL SWITCH
- A. The weights on the level control switch are preset at the factory.
- B. Screw the weight assembly onto the bottom of the switch plunger.
WIRING
- A. Run wire from entrance panel or other adequate source to junction box. Direct bury or individual stranded wire in conduit may be used. Two wires and ground are required for the pump and an additional 2 wires (14 ga.) are required for alarm.
- B. Enter the 1-1/2″ conduit flange and pull the wires up into the junction box so the leads stick out about 6″. The alarm wires should be marked or color coded so they can be identified.
- C. The incoming lines must be sealed to keep condensation moisture or ground water from entering the junction box.
CONNECTING PUMP, SWITCH AND ALARM
- A. Connect black wire from pump to black wire on ALC (black) switch.
- B. Connect white wire of pump to white wire of incoming power.
- C. Connect the 2 wires from the alarm switch (orange ball) to the 2 incoming alarm wires.
- D. Connect incoming ground wire to green wire of pump.
- E. Make sure wire connections are correct and secure. Push wires into box and put on cover. Make sure the cord grips around the incoming cables are snug.
The fiberglass basin cover may be locked by inserting padlocks through the holes on each side of the cover. If locking is not required, the cover may be held on by bolts supplied.
CONNECTING ALARM
Two types of alarms are available:
- Inside alarm fastens to inside wall and plugs into 110V outlet. Audible alarm warns of high water. Unit also has alarm silence and test switch.
- Outside alarm fastens to side of house or post and has red flashing light. This alarm has 2 circuit breakers, one for pump and one for the alarm. Terminal blocks are supplied for connecting the pump and alarm wires and the enclosure is lockable.
