INSTALLATION

WARNING! Risk of electric shock. The pump

is supplied with a grounding conductor and

grounding-type attachment plug on the power

cord. To reduce the risk of electric shock, be

certain that it is connected only to a properly

grounded, grounding-type receptacle. Do not cut

off the ground pin or use an adapter ﬁtting.

WARNING! The basin or tank must be vented in

accordance with local plumbing codes. These

pumps are not designed for and cannot be

installed in locations classiﬁed as hazardous in

accordance with the Canadian Electrical Code (CE)

and the Canadian Centre for Occupational Health

and Safety (CCOHS).

CAUTION! Never enter the pump chamber after sewage

or efﬂuent has been in the basin. Sewage water can

give off methane, hydrogen sulﬁde and other gasses

which are highly poisonous.

The dosing tank or pumping chamber must be

constructed of corrosion resistant materials and must

be capable of withstanding all anticipated internal and

external loads. It also must not allow inﬁltration or

exﬁltration. The tank must have provisions for anti-

buoyancy. Access holes or cover must be adequate

size and be accessible from the surface to allow for

installation and maintenance of the system. Access

covers must be lockable or heavy enough to prevent easy access by unauthorized personnel. The

pumping chamber holding capacity should be selected to allow for emergency conditions.

The discharge pipe must be the same size as the pump discharge (2 inches) or larger. In order to

insure sufﬁcient ﬂuid velocity to prevent any residual solids from collecting in the discharge pipe. It is

recommended that a minimum ﬂow of 2 inches per second be maintained. (12 GPM through 1-1/2 in.

pipe, 21 GPM through 2 inch pipe and 46 GPM through 3 inch pipe). It is recommended that PVC or

equal pipe is used for corrosion resistance. A full ﬂow (ball or gate) shut off valve must be installed to

prevent back ﬂow of efﬂuent if the pump must be removed for service. A check valve must be installed

on pressure sewer systems and on other systems where conditions allow to prevent backﬂow and to

reduce wear on the pump system.

A high water alarm must be installed on a separate circuit from the pump circuit. The alarm should

have the ability to be tested for proper operation.

1. Place the pump on a hard, level surface in a suitable, gas-tight basin that is at least 11 in.

(28cm) diameter and 18 in. (46 cm) deep (see ﬁgure 1).

NOTE: Never place the pump directly on clay, earth, or gravel surfaces.

2. Install the pump with ABS, PVC, polyethylene, or galvanized steel pipe. Use the proper

adapters to connect plastic pipe to the pump.

3. Install a check valve in the discharge line to prevent the backﬂow of liquid into the basin. The

check valve should be free-ﬂow valve that will easily pass solids.

CAUTION! For the best performance when handling solids, install the check valve

horizontally or at an angle of no more than 45°. Do not install the check valve vertically

because solids may settle in the valve and prevent it from opening on start-up.

4. When using a check valve, drill a 1/8 in. (3.175 mm) or 3/16 in. (4.8 mm) diameter relief hole

in the discharge pipe below the ﬂoor line between the pump discharge and the check valve.

Otherwise, the pump could air lock and will not pump water even though the pump will run.

See ﬁgure 1.

TESTING

NOTE: When the pump is installed in a basin with a sealed cover, you cannot observe the operation of

the ﬂoat switch. The cover usually will have a spare hole that is blocked with a rubber plug. Remove

this plug to observe the switch operation during testing.

1. Check the pump label for proper voltage required.

WARNING! Do not connect to a voltage other than that shown.

2. Plug the power cord directly into a GFCI equipped electrical outlet.

3. Run water into the basin until the pump starts.

4. Be sure the check valve in the discharge line is open.

5. Allow the pump to operate through several on / off cycles.

MAINTENANCE

CAUTION! Always unplug the power cords or turn off all main and branch circuit breakers before

doing any work on the pump. If the control panel is remote from the pump, disconnect the lead

wires to the motor so that no one can turn the circuit breaker back on.

1. Cycle the pump at least once every month to be sure that the system is working properly.

2. Before removing the pump from the basin for service, always disconnect the electrical power

source to the pump and the control switch. Do not lift the pump by the power cord.

WARNING! Sudden starts. If the power is on to the pump when the thermal overload resets, the

pump may start without warning. If you are working on the pump, you may get an electrical shock

or the impeller may catch ﬁngers or tools.

WARNING! Disconnect the pump from the power source before servicing.

NOTE: This pump has no serviceable parts. The motor housing of the pump is completely sealed and

requires no service. Disassembly of the motor housing or alteration of the power cord will void all

warranties. The power cord on this pump cannot be replaced. If it becomes damaged, the entire pump

must be replaced.
