Pumps Not Operating or in
Storage:

Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 months
or longer and prior to electrical
start-up.

2

Pumps with tungsten carbide seals
must have impellers manually
rotated (6 revolutions) after setting
non-operational for 3 weeks or
longer and prior to electrical
start-up.

Seal Failure:

An electrode is installed in the seal
chamber so if any water enters the
chamber through the first seal the
electrode will be energized and a
signal will be trans mit ted to the
sen sing unit at ground surface
causing a red light to turn on.
The elec trode probe is installed
in all units, but the sensing unit
is supplied at extra cost and must
be ordered.

In operation the seal failure
unit in di cates only that there is
some water in the seal chamber.
The pump will con tin ue to
operate, but the seal should be
checked im medi ate ly after failure
is indicated.

The sensing unit is recommended
on all installations as good
insurance against motor failure.

Pump:

The submersible pumps in this
manual are supplied for 1 and 3
phase and for 200, 230, 460 or
575 volts. Power cable is supplied
with the green wire for ground. Be
sure green wire is connected to a
good ground such as water pipe or
ground stake.

Heat Sensors:

All motors have heat sensor units
em bed ded in the motor winding
to detect ex ces sive heat. The
heat sen sors are set to trip at
130°C. The sensors au tomatically
reset when motor cools to
safe temperature.

The sensors are connected in
series with the motor starter coil

so that the starter is tripped if heat
sensor opens. The motor starter is
equipped with overload heaters so
all normal over loads are protected
by the starter.

IMPORTANT: If Hydromatic®
electrical starting equip ment is
not supplied, the heat sensor
circuit must be connected in
series with the starter coil
or warranty is void.

Sump Level Control:

Sump level is controlled by
Hydromatic switch controls. The
float is held in position in the
sump by a weight attached to
the power cord above the float.
The cord supports the float
and is adjusted for height from
the surface.

Duplex systems use three
controls: one set at turn-off, one
set at turn-on for one pump, and
one set for turn-on for two pumps.
Pumps alternate op er a tion on each
successive cycle.

Two pumps operate together
only if sump level rises to the
third or over ride control. The
override control also brings on
the second pump in case of failure
of the first pump. Extra floats
with ap propriate controls can
be supplied for alarm functions.
Triplex systems use four controls:
one set at turn-off, one set at turn­on for one pump, one set at turn­on for two pumps, and one set at
turn-on for three pumps. Pumps
alternate each successive cycle.

Three pumps operate together
only if sump level rises to the
fourth control (second override).
This control also brings on the
third pump in case of failure
of either or both of the first
two pumps.

The alarm level is usually set
above the override level so
the alarm will signal only if
the override level is exceeded.

amp draw on these submersible
motors is slightly higher than a
corresponding horsepower surface
motor, so heaters must be sized by
the nameplate rating.

However, some engineers prefer
to have the alarm level set below
the override level as it is pos si ble
for one pump to fail and the other
pump to operate on the override
level with the sump level never

IMPORTANT: Make certain
the heat sensor wires are
connected in series with the
starter coil circuit if other than
Hydromatic starters are used.

par tic u lar ly true in cases of low
inflow capacity.

Installation
Instructions

Electrical Control Panel:

It is recommended that the
Hydromatic control panel be used
with all pumps as proper starter
heat ers and connections for heat
sensor wires are fur nished.

Hydromatic® electrical equipment

NEMA 3R enclosure. The
electrical equipment includes
a main circuit breaker for each
pump, a magnetic starter with
overload protection for each pump,
an H-O-A switch and run light
for each pump, and an electric
alternator and a transformer to
provide appropri ate control for
control circuit and alarms.

Overload Heater:

Starters with 3 leg overload
protection must be supplied if
the Hydromatic electrical panel
is not used. The heaters must
be sized in accordance with the
nameplate amps on the motor. The

Installing Pump in Sump:

Before installing pump in sump,
lay it on side and turn impeller
manually. Im pel ler may be slightly
stuck due to factory test water,
so it must be bro ken loose with
small bar or screwdriver in edge
of vanes. The impeller should
turn freely.

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
line is also recommended. This
valve should be installed on the
discharge side of the check valve
so the line pressure can be cut
off if necessary to service the
check valve. Single pump systems
are sometimes installed without a
check valve where it is desirable
to self-drain the dis charge line to
prevent freezing. This can be done

Sensor Wires Ground Wires

only with short discharge lines.
Otherwise water will return to the
sump and cause short cycling of
the pump.

NEMA 4 Junction Box
(Optional):

A NEMA 4 junction box should
be used to make power and control
con nec tions if electrical control
panel is to be set remote from
the pump sump. The Hydromatic
NEMA 4 junction box is provided
with com pres sion con nec tors
for sealing all wires. No sealing
compound is need ed to make
connec tions wa ter proof.

Wiring diagrams are provided with
the panel for making connections.
The size wire to use from the panel
to sump de pends on motor size
and distance in feet.

Be sure each wire is checked
out so that a wrong connection
will not be made. An ohm me ter
or Megger can be used to check
wire continuity.

Installing Switch Controls:

The controls are supported by a
mount ing bracket that is attached
to sump wall, cover, or to the
NEMA 4 junction box.

Cord snubbers are used to hold
the cord in place. Control level
can be changed at any time by
loosening the snubber and
readjusting cord length.

HEAT SENSOR & SEAL FAILURE

In either a simplex or duplex
system, the lower or turn-off
control is set just above the top
of volute, so that the volute will
always be submerged during
the pumping cycle. The sec ond,
or turn-on control, is set about
24 inches above the lower
turn-off con trol.

More distance between turn-on
and turn-off controls can be used,
but sew age may become septic,
and excessive solids may collect
for the pump to handle. A frequent
pumping cycle is recommended
for best op er a tion.

If an alarm system is used,
this con trol is usually set about 6
inches above the override control.

Making Electrical Connections:

All electrical wiring must be in
ac cor dance with local codes,
and only competent electricians
should make the installations.
Complete wiring diagrams are
glued to the inside cover of the
panel. All wires should be checked
for grounds with an ohm me ter or
Megger after the connections are
made. THIS IS IMPORTANT,
AS ONE GROUNDED WIRE
CAN CAUSE CON SID ER ABLE
TROU BLE.

IMPORTANT: If equipment
is not properly wired and
protect ed as recommended, the
warranty is void.

Heat Sensors and Seal Failure
Connections:

Be sure heat sensor wires are
connect ed in series with the starter
coil. Connections are provided on
the terminal strip.

Pump
Operations

Starting System:

1. Turn H-O-A switch to Off
position and then turn on
main circuit breakers.

2. Open all discharge valves and
allow water to rise in sump.

3. 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 motor 3ø only. Do not
interchange main incoming
lines. If duplex system,
check second pump in the
same manner.

4. Now set both H-O-A switches
to Auto position and allow
water to rise in sump until one
pump starts. Allow pump to
op er ate until the level drops
to turn-off point.

5. Allow sump level to rise to
start other pump. Notice run
lights on panel. Pumps should
alternate on each successive
cycle of op er a tion.

6. Turn both H-O-A switches
to Off position and allow
sump to fill to the override
control level.

7. Turn both switches to Auto
po si tion and both pumps
should start and operate
together until level drops to
turn-off point.

8. Repeat this operation cycle
sev er al times before leaving
the job.

9. 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 (5 to 10%)
without causing trouble.
For excessive amp draw on
one leg, the power company
should be con sult ed.

Phase Converters:

Phase converters are generally
not recommended, but in cases
where only single phase current
is available, phase converters can
be used. Be sure to size the phase
converter large enough for the
amp draw specified on the motor
nameplate, not necessarily by
motor horsepower. The warranty
on all three phase submersible
motors is void if operated with
single phase power through a
phase converter, and 3 leg ambient
compensated extra-quick trip
overload protectors are not used.
