Recommendations and Warnings
Receiving inspection
Upon receiving the pump, it should be inspected for damage or shortages. If
damage has occurred, file a claim immediately with the company that delivered
the pump. If the manual is removed from the packaging, do not lose or
misplace.
Storage
Any product that is stored for a period longer than six (6) months from the
date of purchase should be bench tested prior to installation. A bench test
consists of, checking the impeller to assure it is free turning and a run test
to assure the motor (and switch if provided) operate properly.
Controls
Manual models require a separate approved pump control device or panel for
automatic operation. Be sure the electrical specification of the control
selected properly match the electrical specifications of the pump.
Submergence
The pump should always be operated in the submerged condition. The minimum
sump liquid level should never be less than above the pump’s volute (See
Figure 1).
Liquid Level Control
Typical Discharge Pipe Mounted: Refer to Figure 2 below which shows a typical
installation of a 1 phase 115 volt pump using a level control mounted to the
discharge piping with a piggyback plug. The level control should have adequate
clearance so it cannot hang up in it’s swing and that the pump is completely
submerged when the level control is in the “Off” mode. By adjusting the cord
tether the control level can be changed.
Typical Discharge Pipe Mounted Level Control
Level Control Basic instructions
Plug the level control plug into the GFI receptacle, then plug the pump
into the piggy-back plug (See Figure 3). One cycle of operation should be
observed, so that any potential problems can be corrected.
It is recommended that the level control float should be set to insure that
the liquid in the sump never drops below the top of the motor housing or a
minimum level of 6 inches above the basin floor.
Installation
Installation
These pumps are recommended for use in a sump or basin. The sump, basin or
lift station shall be sealed and vented in accordance with local plumbing
codes. This pump is designed to pump sewage, effluent or wastewater, non-
explosive and non-corrosive liquids and shall NOT be installed in locations
classified as hazardous in accordance with the National Electrical Code (NEC)
ANSI/NFPA 70 or Canadian Electric Code (CEC). The minimum sump depth should be
at least 24″. Check the dimensions for minimum sump diameter. These are
minumum requirements.
The pump should never be installed in a trench, ditch, or hole with a dirt
bottom. The legs will sink into the dirt and the suction will become plugged.
- Excavation: Excavate the hole as small as possible, with minimum recommended 8″ diametrical clearance around the tank. Never place basin directly in contact with rocks or other sharp objects. Place only fine, 1/8″ to 3/4″ pea gravel or 1/8″ to 1/2″ washed, crushed stone as bedding between the basin and the hole walls. Do not use sand or native soil as backfill. Properly compact underneath the basin to provide a solid level base that can support the weight of the filled basin.
- Inlet Connection & Initial Backfill: Only fine, 1/8″ to 3/4″ pea gravel or 1/8″ to 1/2″ washed, crushed stone should be used around the bottom of the basin to hold it in place. Do not use sand or native soil as backfill. Make the inlet connection as required for your basin.
- Final Backfill: Only fine 1/4″ to 3/4″ pea gravel or 1/8″ to 1/2″ washed crushed stone is recommended. Do not use sand or native soil as backfill.
Discharge Piping
Discharge piping should be as short as possible and sized no smaller than the
pump discharge. Do not reduce the discharge pipe size below that which is
provided on the pump. Both a check valve and a shut-off valve are recommended
for each pump. The check valve is used to prevent backflow into the sump. The
shut-off valve is used to manually stop system low during pump servicing.
Electrical Connections Power cable:
The power cable mounted to the pump must not be modified in any way except
for shortening to a specific application. This pump is provided with a 3 wire
cord and 3 prong grounded plug that must be connected into a 3 wire grounded
Ground Fault receptacle. DO NOT USE THE POWER CABLE TO LIFT PUMP. Do not use
an extension cord.
Always rely upon a Certified Electrician for installation.
Overload Protection:
Single Phase – The stator in-winding overload protector used is referred to as
an inherent overheating protector and operates on the combined effect of
temperature and current. This means that the overload protector will trip out
and shut the pump off if the windings become too hot, or the load current
passing through them becomes too high.
IMPORTANT – The overload will then automatically reset and start the pump up after the motor cools to a safe temperature. In the event of an overload, the source of this condition should be determined and corrected immediately.
Pre-Operation
- Check Voltage and Phase -Compare the voltage and phase information stamped on the pump name plate.
- Check Pump Rotation – Improper motor rotation can result in poor pump performance and can damage the motor and/or pump. Incorrect rotation for Single-Phase pumps is unlikely. If the rotation is incorrect contact factory.
- Name Plate – Record the information from the pump name plate to drawing in front of manual for future reference.
- Insulation Test – An insulation (megger) test should be performed on the motor. Before the pump is put into service. The resistance values (ohms) as well as the voltage (volts) and current (amps) should be recorded.
- Pump-Down Test – Be sure pump has been properly wired, lowered into the basin, sump or lift station, check the system by filling with liquid and allowing the pump to operate through its pumping cycle. The time needed to empty the system, or pump-down time along with the volume of water, should be recorded.
Troubleshooting Chart
Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
Symptom| Possible Cause(s)| Corrective Action
Pump will not run
|
- Poor electrical connection, blown fuse, tripped breaker or other interruption of power; improper power supply
- Motor or switch inoperative (go to manual operation)
- Float movement restricted
- Switch will not activate pump or is defective
- Defective motor
- Insufficient liquid level
|
- Check all electrical connections for security. Have electrician measure current in motor leads, if current is within ± 20% of locked rotor Amps, impeller is probably locked. If current is 0, overload may be tripped. Remove power, allow pump to cool, then re-check current.
- Reposition pump or clean basin as required to provide adaquate clearance for float
- Disconnect level control. Set ohmmeter for a low rang, such as 100 ohms full scale and connect to level control leads. Actuate level control manually and check to see that ohmmeter shows zero ohms for closed switch and full scale for open switch. (Float Switch)
- Check winding insulation (Megger Test) and winding resistance. If check is outside of range, dry and re-check. If still defective, replace per service instructions.
- Make sure liquid level is above the pump
- Re-check all sizing calculations to determine proper pump size.
- Check discharge line for restrictions, including ice if line passes through or into cold areas.
- Remove and examine check valve for proper installation an o d freedom of op m eration
- Open valve
- Check impeller for freedom of operation, security and condition. Clean impeller cavity and inlet of any obstruction
- Loosen union slightly to allow trapped air to escape. Verify that turn-off level of switch is set so that the suction is always flooded. Clean vent hole
- Check rotation. If power supply is three phase, reverse any two of three power supply leads to ensure proper impeller rotation
- Repair fixtures as required to eliminate leakage
- Check pump temperature limits and fluid temperature
- Replace portion of discharge pipe with flexible connector or tighten existing piping.
- Turn to automatic position
