WARNING

I nstalla tion and servicing is to be conducted by qualied personnel only.

Keep clear of suction and discharge openings. Do not

insert ngers in pump with power connected; the impeller can cause serious injury.

Always wear eye protection

when working on pumps. Do

not wear loose clothing that may become entangled in moving parts.

DANGER

Pumps build up heat and pressure during operation. Allow time

for pumps t o c ool before handling or servicing the pump or a ny accessor y i tems associated with or near the pump.

DANGER

T his pump is not

i n t ended f or use in swimming pools or water installations where there is

human contact with pumped uid.

DANGER

Risk of electric shock. To

reduce risk of electric shock, always disconnec t pump

from power source before handling any aspect of the pumping system. Lock out power and tag.

WARNING

Do not use these

pumps in water over 104º F. Do not exceed manufacturers recommended maximum performance, as this could cause the motor to overheat.

DANGER

Do not lift, carry or

hang pump by the electrical

cables. Damage to the

electrical cables can cause shock, burns or death. Never handle connected power cords with wet hands. Use appropriate lifting device.

WARNING

Sump and sew age pumps often handle materials which could cause illness or disease. Wear adequate protective clothing when working on a used pump or piping. Never enter a basin after it has been used.

DANGER

Failure to permanently

ground the pump, motor and controls before connecting to power can cause shock,

burns or death.

DANGER

These pumps are not to

be installed in locations classied as hazardous in accordance with the National

Electric Code, ANSI/NFPA 70.

WARNING

The Uniform Plumbing Code ( UPC ) sta tes that sewage systems shall have an audio and visual alarm that signals a malfunction of the systems, that are required to reduce the potencial for property damage.

IMPORTANT! - Prior to installation, record Model Number, Serial, Amps, Voltage, Phase and HP from pump name plate for the future reference. Also record the Voltage and Current Readings at Startup:

Recommendations and Warnings

Receiving inspection

Upon receiving the pump, it should be inspected for damage or shortages. If damage has occurred, le 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 ele control selected properly match the electrical specications of the pump.

ctrical specication of the

Installation

There are two methods of installing euent pumps:

1. In a Flex-Hose system, most commonly used in interceptor tanks, and

2. A slide rail in a package system or concrete wet well, which allows the pump(s) to be installed or removed without requiring personnel to enter the wet well.

The sump, basin or lift station shall be sealed and vented in accordance with local plumbing codes. This

pump is designed to pump sewage, euent or wastewater, non-explosive and non-corrosive liquids and shall NOT be installed in locations classied as hazardous in accordance with the National Electrical Code (NEC) ANS 70 or Canadian Electric Code (CEC).

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.

Liquid Level Controls

Typical Discharge Pipe Mounted:

Refer to Figure 2 below which shows a typical installation of a 1 phase 120 or 240 volt pump using a level control mounted to the discharge piping with a piggy-back 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 "O" mode. By adjusting the cord tether the control level can be changed.

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).

Minimum Submergence Level

Bottom of Feet

Figure 1

The installation should be at a sucient depth to ensure that all plumbing is below the frost line. If this is not feasible, remove the check valve and size the basin to accommodate the additional backow volume.

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-o valve are recommended for each pump. The check valve is used to prevent backow into the sump. The shut-o valve is used to manually stop system low during pump servicing.

Drill ¼" dia. vent hole to prevent air locking

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 oat 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 oor.
