4. Use steel or plastic pipe for all connecting lines
between pump and sewer outlet.
Note:
Some city regulations do not allow installing a
pump with plastic pipe. Check local regulations.
5.
Drill a 1/8″ inch hole into discharge pipe 4 inches
above the pump’s discharge.
6. A check valve should be installed in discharge
pipe, above the cover of the basin.
7. Connect to power source using 3-prong
grounded 115 volt AC receptacle. Do not remove
ground pin from electrical plug. Do not use an
extension cord.
8. Use pump submerged for sump, dewartering
applications (temperature to 120° F).
9. In applications where the pump may sit idle for
months at a time, it is recommended that the
pump(s) be cycled every few months to ensure
the pumping system is working properly when
needed.
10. An audible alarm for high water conditions
should be installed for additional protection
against high water conditions.
Your pump warranty is void...
If...power cord has been cut.
If...pump has been used to pump mud, cement,
tar, abrasives or chemicals.
If...pump has been used for pumping hot water
(above 120°F ).
If...cord tag has been removed.
Servicing should be performed only by an authorized

Note:
Automatic thermal overload protects the sealed-
in-oil motor. Running dry may overheat the motor and
activate the overload protector until the unit cools.
Pump does not run or just hums.
1. Line circuit breaker may be off, blown or loose.
2. Cord prong may not be making contact in
receptacle.
3. If all symptoms check okay, motor winding may
be open; take to authorized service center for
check.
Pump runs but does not deliver water.
1. Check valve may be installed backward. Arrow
on valve points in direction of flow.
2. Discharge gate valve, if used, may be closed.
3. Pump may be air locked. Start and stop several
times by plugging and unplugging cord. Check
vent hole in pump case for plugging.
4. Ion
®
Technologies pumps have a small air vent
hole in the impeller cavity to let out trapped air. If
this hole becomes plugged, pump may air lock.
To break the air lock, use a small screwdriver to
clear hole in the impeller cavity.
5. As a secondary precaution in installations of this
type –
1
/
16
″ hole should be drilled in the discharge
pipe below the check valve. The check valve
should be installed in pump discharge above the
cover on the basin.
Note:
In sumps where the pump is operating daily, air
locking rarely occurs.
1. Pump head may be too high. Pump cannot
deliver water over 33
'
vertical lift. Horizontal
distance does not affect pumping, except for
friction loss through the pipe.
2. Inlet in pump base may be clogged. Remove
pump and clean out openings.
3. Impeller or volute openings may be plugged or
partially plugged. Remove pump and clean out.
