Warning
2. Make sure float (automatic
models) hangs free. It should
not come into contact with
side or bottom of sump pit.
3. Make sure sump is free of
string, cloth, nails, gravel, etc.
before installing pump.
4. Do not set pump directly on
the bottom of sump if it is not
solid. Raise the pump by
placing bricks or concrete
blocks underneath it.
5. 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.
6. Hydromatic check valve
should be installed in
discharge pipe, at least twelve
inches above the discharge
outlet of the pump.
7. Connect to power source
using 3-prong grounded
115/230 volt AC receptacle.
Do not remove ground pin
from electrical plug. Do not
use an extension cord.
8. For proper automatic opera-
tion make sure the pump
power cord is plugged into
the back of the “piggyback”
receptacle on the switch cord.
9. Use pump submerged for
pumping waterlike liquids
(temperature to 120° F).
CAUTION: Do not pump
flammable liquids, strong
chemicals or salt water.
10.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 work-
ing properly when needed.

Pump
Servicing
Servicing should be performed
only by an authorized
Hydromatic service center.
WARNING: Always disconnect
the pump from power source
before handling or making
any adjustments. Always wear
rubber boots when there is
water on the floor and you
must unplug the pump or make
any adjustments.
NOTE: Automatic thermal
overload protects the
sealed-in-oil motor. Running
dry may overheat the motor
and activate the overload pro-
tector until the unit cools.
Pump does not run or
just hums.
1. Line circuit breaker may be
off, blown or loose.
2. Water level in sump may be
too low to activate automatic
float or diaphragm switch.
3. Pump and/or switch cord plug
may not be making contact
in receptacle.
4. If pump is using the series
(piggyback) cord plug, the
two plugs may not be plugged
tightly together.
5. Float may be stuck. Be sure
float operates freely in basin.
6. If the unit is being operated
by the optional float control
switch, unplug the pump from
the piggyback receptacle and
plug the pump directly into
the power source. If the pump
starts each time it is plugged
directly into the receptacle
and does not start each time
when plugged into the piggy-
back switch with the float
raised up to a start position,
replace the complete piggy-
back switch assembly and
retest with new assembly.
7. If all symptoms check OK,
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.
HYDROMATIC 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.
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 12 to 18
inches above pump discharge.
Do not put check valve
directly into pump discharge
opening.
NOTE: In sumps where the
pump is operating daily, air
locking rarely occurs.
4. Pump head may be too high.
Pump cannot deliver water
over 25' vertical lift.
Horizontal distance does not
affect pumping, except for
friction loss through the pipe.
5. Inlet in pump base may be
clogged. Remove pump and
clean out openings.
6. Impeller or volute openings
may be plugged or partially
plugged. Remove pump and
clean out.
Pump runs and pumps out
sump but does not stop.
1. Float is stuck in up position.
Be sure float is not hung up
and operates freely in basin.
2. Switch contacts may be stuck;
replace switch.

LIMITED WARRANTY
HYDROMATIC warrants to the original consumer purchaser (“Purchaser” or “You”) of HYDROMATIC Sump
Pumps, Effluent Pumps, Sewage Pumps (other than 2-1/2"), and Package Systems, that they will be free from
defects in material and workmanship for the Warranty Period of 36 months from date of manufacture.
Our warranty will not apply to any product that, in our sole judgement, has been subject to negligence,
misapplication, improper installation, or improper maintenance. Without limiting the foregoing, operating a
three phase motor with single phase power through a phase converter will void the warranty. Note also that
three phase motors must be protected by three-leg, ambient compensated, extra-quick trip overload relays of
the recommended size or the warranty is void.
Your only remedy, and HYDROMATIC’s only duty, is that HYDROMATIC repair or replace defective products
(at HYDROMATIC’s choice). You must pay all labor and shipping charges associated with this warranty and
must request warranty service through the installing dealer as soon as a problem is discovered. No request
for service will be accepted if received after the Warranty Period has expired. This warranty is not transferable.
EXCEPTIONS: Hydromatic Special Application Pumps, Battery Back-Up Sump Pumps, Filtered Effluent
Pumps, Grinder Pumps, and 2-1/2" Sewage Pumps are warranted for a period of 12 months from date of
purchase or 18 months from date of manufacture, whichever comes first.
HYDROMATIC SHALL NOT BE LIABLE FOR ANY CONSEQUENTIAL, INCIDENTAL, OR CONTINGENT
DAMAGES WHATSOEVER.
THE FOREGOING WARRANTIES ARE EXCLUSIVE AND IN LIEU OF ALL OTHER EXPRESS AND
IMPLIED WARRANTIES, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE FOREGOING WARRANTIES
SHALL NOT EXTEND BEYOND THE DURATION EXPRESSLY PROVIDED HEREIN.
Some states do not allow the exclusion or limitation of incidental or consequential damages or limitations on
the duration of an implied warranty, so the above limitations or exclusions may not apply to You. This warranty
gives You specific legal rights and You may also have other rights which vary from state to state.
This warranty supersedes and replaces all previous warranty publications.
