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. Do not
pump out of liquid.
Controls
Manual models require a separate
approved pump control device or panel
for automatic operation. Be sure the
electrical specifi cation of the control
selected properly match the electrical
specifi cations 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).
Installation
These pumps are recommended for
use in a sump, basin or lift station.
The sump, basin or lift station shall be
sealed and vented in accordance with
local plumbing codes.
This pump is
designed to pump sewage, effl
uent
or wastewater, nonexplosive and
noncorrosive liquids and shall NOT
be installed in locations classifi ed 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 suffi
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
backfl ow volume.
Pumps are most commonly installed
in simplex, duplex or triplex stations or
basins with a slide rail system, which
allows the pump(s) to be installed or
removed without requiring personnel to
enter the station, or resting on the basin
fl oor.
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 flow during
pump servicing.
Liquid Level Controls
The level control(s) should be mounted
on the discharge piping, a cable rack or
fl oat pole. 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. One cycle of operation should
be observed, so that any potential
problems can be corrected.
It is recommended that the level control
fl 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 10 inches above the basin fl oor.
Electrical Connections
Power/control cables:
The power/control cables mounted to
the pump must not be modified in any
way except for shortening to a specific
application. Any splice between the
pump and the control panel must be
made in accordance with the electric
codes. It is recommended that a junction
box, if used, be mounted outside the
sump or be of at a minimum Nema
4 construction if located within the
wet well.
DO NOT USE THE POWER/
CONTROL CABLES TO LIFT PUMP.
Always rely upon a Certifi ed Electrician
for installation.
