CALIFORNIA PROPOSITION
65 WARNING:
This product
and related accessories contain
chemicals known to the State of
California to cause cancer, birth
defects or other reproductive harm.
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.
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 sup plied 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 immedi 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 on the H3H. The sensors
au to matcally reset when motor
cools to safe tem per a ture.
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 pro pri ate controls can be
supplied for alarm functions.
Triplex systems use four controls:
one set at turn-off, one set at
turn-on for one pump, one set
at turn-on 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.
