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).

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.
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 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.
The installation should be at a
sufficient 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
backflow volume.
Installation
There are two methods of installing
effluent 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.
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 "Off" mode. By
adjusting the cord tether the control
level can be changed.

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.
