Pump
Installation
installing Sump Level Control
Float Controls:
In either simplex, duplex or
triplex systems the lower or
turn-off control is to be set to
maintain a minimum level in the
sump. This level shall be no more
than 3 ⁄ " from the top of the
1
4
motor housing down to the
surface of the sewage.
The second or turn-on control is
set above the lower turn-off
control. The exact
between the two floats must be a
compromise between a frequent
pumping cycle (10 starts per hour
max.) to control septicity, solids
and a slower cycle for energy
economy. This distance should be
determined by the engineer or
consulting engineer depending on
the conditions of the application.
For installation of Hydromatic
supplied level controls refer to
your systems installation and
service manual.
installing Pump in Sump:
Before installing pump in sump
lay it on side and rotate impeller.
Impeller may be slightly stuck
due to factory test water so it must
be broken loose with small bar
or screwdriver in edge of vanes.
The impeller should turn freely.
Do not connect the power until
after this test.
Clean all trash and sticks from
sump and connect pump to piping.
A check valve must be installed
on each pump. A gate or plug
valve in each pump discharge
is highly recommended. This
valve should be installed on the
discharge side of the check valve
so if necessary to service the
check valve the line pressure can
be cut off. Single pump systems
are sometimes installed without a
check valve where it is desirable
to self-drain the discharge line to
prevent freezing. This can be done
only with short discharge lines;
otherwise water will return to the
sump and cause short cycling
of the pump.
Making Electrical Connections:
All electrical wiring must be in
accordance with local code, and
only qualified electricians should
make the installations. Complete
wiring diagrams are included
distance
for use in making the installation.
All wires should be checked
for shorts to ground with an
ohmmeter or Megger after the
connections are made. This is
important, as one grounded wire
can cause considerable trouble.
iMPOrTANT: if equipment
is not properly wired and
protected
Hydromatic warranty is void.

Heat Sensor and Seal Failure
Connections:
If a Hydromatic control panel is
used, terminal
provided for heat sensor, seal
failure connections (See Panel
Schematic). If a control panel
is supplied by others, it must
allow heat sensor and seal
failure terminations.

Pump
Operations
Starting System:
1. Double check
connections.
2. Turn pumps to Off position on
H-O-A switches.
3. Turn on breakers.
4. Turn H-O-A switch to Hand
position on one pump and
notice operation. If pump is
noisy and vibrates, rotation is
wrong. To change rotation,
interchange any two line leads
to pump. Do not interchange
main incoming lines. Check
rotation of all pumps in this
same manner.
5. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until one
pump starts. Allow pump to
operate until the level drops
to turn-off point.
6. Allow sump level to rise to
start other pump(s). Notice run
lights to panel. Pumps should
alternate on each successive
cycle of operation.
7. Turn both H-O-A switches to
Off position and allow sump to
fill to the override control level(s).
8. Turn switches to Auto position,
and pumps should start and
operate together until level
drops to turn-off point.
9. Repeat this operation cycle
several times before leaving job.
10.Check voltage when pumps
are operating, and check the
amp draw of each pump. Check
amps on each wire as sometimes
a high leg will exist. One leg
can be somewhat higher by 5
to 10 percent without causing
trouble. For excessive amp draw
on one leg, the electric utility
company should be consulted.
