Myers WHV-5 Waste Handling Sump Pumps

NOTE! To the installer: Please make sure you provide this manual to the owner of the equip ment or to the responsible party who maintains the system.
CALIFORNIA PROPOSITION 65 WARNING:
WARNING This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
The WHV-5 series waste handling pumps are single phase 1/2 HP. Pumps have plug-in cords to operate as a manual pump by plugging directly into a grounded receptacle or  into series plug of switch cord for automatic operation. Cords are furnished in 20′ lengths. Plug is cut off when pump is used for duplex operation so as to connect directly to  terminal block in control box. Also available are pumps with attached control floats for automatic operation.

LEVEL SWITCHES
WHV-5 manual pumps must be used with separate level controls for automatic operation. Switches are sold and packaged separately and come with complete installation instructions.
WHV-5 automatic pumps have their own attached control float switches.

APPLICATIONS
The WHV-5 series waste handling pumps are designed for residential and commercial applications and will handle all wastewater, paper and other material normally found in  sewage. Pump will handle 2″ diameter solids. Not intended to pump large rags or mop heads.

PIPING
Pump case is fitted with 2″ NPT female thread for 2″ standard pipe.
Pipe can be galvanized steel or schedule 80′ plastic pipe. Schedule 40 plastic pipe can be used with proper cement adapters.

CHECK VALVE
A 2″ check valve must be used at pump discharge.
This should be a free-flow valve that will easily pass solids. The Myers CV-200 valve is designed especially for this service.

INSTALLATION

The WHV-5 waste handling pump is always installed in a gas tight sump basin. Myers offers complete packaged basin systems for simplex and duplex operation. Packaged  basin systems include all parts except pump, level control, check valve, pipe and duplex control box. The WHV-5 pumps should be used in 24″ dia. or larger basins. Do not use WHV-5 in an 18″ diameter basin.

SIMPLEX BASIN
The B20-3036 basin package is for 1/2 HP pumps and has a 30″ x 36″ fiberglass basin with a steel basin cover and two cast iron pump covers. One cover is blank, for  installation of second pump at later date if required, other cover has flange for 2″ or 3″ discharge pipe and has flange for mounting switch. Basin has 3″ vent flange and inlet  flange for 4-1/2″ O.D. plastic pipe. This basin gives extra storage capacity needed for the larger pumps.

DUPLEX BASIN
The B20-3036D and B30-3036D basin systems are for duplex operation. This system has a 30″ x 36″ fiberglass basin with steel basin cover that supports two separate cast iron covers. Covers have sealing flange for discharge pipe either 2″ or 3″ as ordered. Covers also have mounting flanges for switches. Basin has 3″ vent flange and inlet flange  for 4-1/2″ O.D. plastic pipe. An inlet flange for 6-5/8″ O.D. plastic pipe, catalog number 1F-600 is also available. Inlet flanges are shipped loose for mounting in the field at inlet height required.

SUMP COVERS
Myers offers separate pump covers for simplex and duplex systems to be used with existing basin as a replacement, or with customer basin.
Cover BC20-30D is for duplex system in 30″ diameter basin with flange for 2″ discharge pipe.
Cover BC30-30D is for duplex system in 30″ diameter basin with flange for 3″ discharge pipe.
With separate cover, the steel basin cover must be sealed to basin top with caulking compound. All covers include switch mounting flange and 3″ vent flange.

INSTALLING BASIN SYSTEMS

The sump basin is usually installed at time of pouring cement floor so that it can be cemented in place, level with the floor.
Pumps are installed after construction is completed.
Covers should be left on basin until after construction, so trash will not accumulate in basin.
Check basin before installing pump and remove any rocks, cement chunks or other trash that could damage pump.
Inlet flange is installed in the field and hole cut in basin at height required. More than one inlet flange can be used if required to bring extra lines into basin.
CAUTION – Before installing pump in basin, turn pump on side and turn impeller with screwdriver in slotted shaft. Impeller must turn free on this test. Pump cord is sealed  through cover with split rubber bushing.

INSTALLING CHECK VALVE
The check valve is always installed in horizontal position to prevent solids from settling on top of clapper, causing clogging. A union and gate valve are recommended for use  in discharge pipe to provide easy removal of pump.

STARTING PUMP – SIMPLEX SYSTEM, AUTOMATIC PUMP

1. Plug pump cord into 115 or 230 volt grounded receptacle. The 230 volt receptacle has in-line blade openings so that 115 volt plug cannot be plugged in.
   CAUTION – Never cut off grounding pins or use an adapter to plug into an ungrounded receptacle.

2. Run water into sump until control turns on pump. Allow pump to operate until level drops, turning pump off.

3. Run pump through several cycles to check switch operation.

4. If pump runs but does not deliver water, stop and start pump several times by unplugging and plugging in cord to clear air.
   Also, make sure the check valve is installed properly, with flow arrow in the correct direction.
   Check elevations of discharge piping that the height of the discharge is not greater than the total head capability of the WHV-5.

5. If pump does not start at all, the trouble could be in the wiring, float switch, or the pump itself.

STARTING PUMP WHV-5P (AUTOMATIC) USING MECHANICAL SWITCH WITH SERIES PLUG – SIMPLEX SYSTEM

1. These pumps have a mechanical (mercury-free) float switch with a 10 ft. or 20 ft. cord with a 115 volt or 230 volt series piggyback plug with switch mounted to the  pump.
2. Plug the switch cord plug into a proper voltage, properly grounded outlet.
3. Plug the pump power cord into the back of the switch cord.
4. Tape the cords to the discharge pipe every 12″.
5. Run water into sump until pump starts. Be sure discharge line valve is open.
6. Allow pump to operate through several on/off cycles.

SETTING LEVEL CONTROLS – SIMPLEX SYSTEM WITH CONTROL PANEL
Three FLC mercury floats are used for simplex operation. Cords from these controls must be marked so they can be connected to proper terminals in the control box.
The turn ON float should be set so that the water level raises at least to the top of the WHV-5 pump’s motor housing before the pump turns on. With the WHV-5 setting on  the basin bottom, this height would be 14″ minimum above the bottom of the basin. The setting of the ON float may be set as high as 6″ below the bottom of the inlet pipe  coming into the basin.
Set the OFF float such that there is 6 to 7″ of water remaining in the basin. The water level should not drop below the junction point of the WHV-5 volute case and motor  housing.
The HIGH WATER (alarm) float should be set so that the water level is 4″ above the level at which the pump turns on.

STARTING PUMP – SIMPLEX SYSTEM WITH CONTROL PANEL

1. Turn HAND-OFF-AUTO switch to OFF position and close circuit breaker. Turn HAND-OFF-AUTO switch to the AUTO position and run water into the sump or  basin.
2. When water level reaches the ON float switch, the pump should start and run. Yellow indicator light on the panel will be illuminated. Pump will lower water level to the  OFF float switch and the pump will stop.
3. If the float switches are not set at the correct heights to result in the water levels as described above, turn the HAND-OFF-AUTO switch to OFF and adjust the float  switches heights. Repeat Steps 1 and 2.
4. If for any reason the water level reaches the HIGH WATER float, the alarm light or buzzer will be activated. Alarm will stop as soon as level drops below the HIGH  WATER float.
5. If pump operates as described, set HAND-OFF- AUTO switch to AUTO position and pumps are ready for service.
6. If pumps do not operate properly, make checks, as given in Steps 4 and 5, of STARTING PUMP, SIMPLEX SYSTEM, AUTOMATIC PUMP. Set HAND-OFF-AUTO  switch to HAND position to check operation of the pump.
7. Check for electrical trouble – explained in the control box instructions. A competent electrician should make checks in the control box to locate trouble.
   CAUTION – NEVER WORK ON PUMPS OR CONTROL BOX UNTIL CIRCUIT BREAKER IS TURNED OFF.

SETTING LEVEL CONTROLS – DUPLEX SYSTEM WITH CONTROL PANEL
Four FLC mercury floats are used for duplex operation. Cords from these controls must be marked so they can be connected to proper terminals in the control box.
The turn ON float should be set so that the water level raises at least to the top of the WHV-5 pump’s motor housing before the lead pump turns ON. With the WHV-5  setting on the basin bottom, this height would be 14″ minimum above the bottom of the basin. The setting of the ON float may be set as high as 12″ below the bottom of the  inlet pipe coming into the basin.
Position the lag pump ON (override) float switch about 6″ above the lead pump ON float.
Set the OFF float such that there is 6 to 7″ of water remaining in the basin. The water level should not drop below the junction point of the WHV-5 volute case and motor  housing.
The HIGH WATER (alarm) float should be set so that the water level is 4″ above the level at which the lag pump turns on.

STARTING PUMP – DUPLEX SYSTEM WITH CONTROL PANEL

1. Turn both HAND-OFF-AUTO switches to OFF position and close circuit breaker.

2. Turn both HAND-OFF-AUTO switches to the AUTO position and run water into the sump or basin.

3. When water level reaches the first ON float switch, one pump should start and run. Yellow indicator light on the panel will be illuminated for the operating pump.
   Pump will lower water level to the OFF float switch and the pump will stop.

4. Run water into the sump again. When water level reaches the first ON float, the opposite pump will start. The yellow light will show which pump is operating.

5. This cycle will continue and pumps will alternate on successive cycles.

6. If excessive flow enters the basin that is more than one pump can handle, the sump level will rise and activate the override float, which will start both pumps and activate the alarm.

7. The same condition can occur if one pump fails for any reason. Then level will rise to the override float, and the good pump will start and operate until failed pump is replaced or repaired. If for any reason level reaches fourth float, alarm light or buzzer will be activated. Alarm will stop as soon as level drops below the alarm float.

8. To check override operation, turn both HAND-OFFAUTO switches to OFF position and fill basin until level is above override float (3rd float).

9. Turn both HAND-OFF-AUTO switches to AUTO position and both pumps should start.

10. Repeat this operation with one pump off, which will duplicate a failed pump condition. In this case, when level reaches override float, the pump that is in the ON position should start. Operation will continue on this one pump.

11. lf pumps operate as described, set both HANDOFF-AUTO switches to AUTO position and pumps are ready for service.

12. lf pumps don’t operate properly, make checks as given for simplex system. Use HAND-OFF-AUTO switch in HAND position to check operation of each pump.

13. Check for electrical trouble given in the control box instructions.
    A competent electrician should make checks in the control box to locate trouble.
    CAUTION – NEVER WORK ON PUMPS OR CONTROL BOX UNTIL CIRCUIT BREAKER IS TURNED OFF.

CHECK POINTS IF PUMP DOES NOT RUN AND OPERATE PROPERLY

1. Be sure fuse is not blown or circuit breaker is not tripped. Pump should have separate circuit with its own fuse or breaker. If on circuit with other equipment, nuisance tripping may occur.
2. CAUTION – Always unplug pump cord before removing pump from sump basin. Remove pump and check for plugged inlet or trash stuck in pump. Be sure pump impellers turn freely after removing any trash.
3. If pump does not operate after cleaning, stator may be damaged or burned out. Occasionally, lightning may damage a motor.
