INTRODUCTION
Manufactured unit. It should be given the same attention
accorded to any precision machine.
The satisfactory operation of this controller depends to a
large extent upon proper installation. These in-structions
cannot answer every question that may arise as each
installation will be different. The installer and the
operator of this equipment must use good judgment to
adapt these procedures to the installation.
INSTALLATION
temporarily encircle the roll with tape to secure.
Carefully lower the Electrode Housing assembly, bulb
first, through the opening in the cover over the basin until
the mounting flange rests on the basin cover. Remove
tape.
MOUNTING FLANGE: The Sealtrode Series P Pump
Controller is furnished with one of two styles of mounting
flanges: standard for mounting on metal basin covers,
and style F for concrete mounting, both illustrated on
page 5.
The Mounting Flange (15) has been preset at the factory
for the correct basin depth and should require no further
adjustment. Refer to page 5 for factory settings.

TERMINAL HOUSING ASSEMBLY: For aid in
installation the factory has pre-assembles the terminal
housing (27) reducer tee (12) and compression coupling
(13) together. This assembly also includes the
suspension wires (18), electrodes (19) and fill-vent tee
(5).
Remove tape from and straighten the electrode wires.
Remove kinks if necessary. Make sure all wires are
marked. Wire “A” is the longest, wire “B” is the next
longest, etc.
Feed electrodes (19) and wires (18) into the Electrode
Housing, being careful not to tangle or twist wires. Place
terminal housing assembly on top of Electrode Housing
(17) and press down on terminal housing assembly until
pipe is inside of compression coupling (13). Hold the
terminal housing in position and screw the cap on the
compression coupling until the assembly is secured to
the electrode housing (17).
VENT: Atmospheric venting is required for this unit to
operate. In normal, non-explosive atmospheres, venting
is accomplished via the small pierced hole in the metal
closure installed in the side opening of the fill-vent tee. If
the terminal housing is to be installed in an explosive
atmosphere, pry the metal closure from the tee and
discard. The exposed vent opening should be connected
to uncontaminated air by means of pipe or tubing. The
opening is threaded behind the closure to accommodate
a ¾” pipe fitting.
CAUTION
Never block, plug or close off Vent openings. Inspect
closure for presence of pierced hole and add if missing.
This device will not function without venting.
FILLING FLEXIBLE BULB: Fill the basin with water to
a level approximately 4” below the cap to which the bulb
is attached. Remove the plug from the top of the fill-vent
tee. Tee is located near the terminal housing. Pour in the
electrolytic solution (a mixture of 3 ½ quarts of distilled
water and one (1) package of sodium bicarbonate.)
Replace the top plug.
WARNING
Before attempting repairs to
installation, disconnect the power supply. Controls
are automatic. This prevents accidental running of
pump motor. Starting motor during repair activities
could damage pump and may cause personal injury.
WIRING: Remove the cover (1) from the terminal
housing and install conduit from the housing to the
control box. Use 14 AWG wire with 600 volts rated
insulation and 3/64 inch minimum insulation wall
thickness to connect the letter coded wires to the
indicated terminals in the control box. Be sure electric
current is the same as that stamped on the control box
nameplate. Wire per wiring diagram supplied with
control panel. If diagram is lost or misplaced copies may
be obtained from your local Peerless Pump
representative.
NOTE: When the Sealtrode Control Box is remotely
located the distance from the SEALTRODE in the
pumping station to the control box or panel should not
exceed 100 feet.
Two separate metallic conduits are required from the
pumping station to the building housing the control, one
for the SEALTRODE r wires and one for the wires
between the motors and controls.
GENERAL: The installation of the controller is now
completed and the level within the 1 ½” Electrode
Housing will faithfully duplicate the liquid level in
the basin actuating the control as the liquid rises
and falls and making and breaking contact with the
electrodes.
HOW TO ADJUST ELECTRODE SETTING: The
electrode elevations have been pre-set at the factory
and no further adjustment should be necessary. Should
it be desirable, however, to readjust the factory settings
refer to page 5 and note the assembly arrangement for
anchoring the wires within the terminal housing. Also
refer to page 5 and note and select the proper letter
coded wire to be adjusted.
To adjust electrode remove the terminal housing cover
(1) and slowly loosen the compression fitting (8) just
enough to be able to slide the selected suspension wire
up or down as required. When adjustment has been
made, re-tighten the compression fitting.
There is sufficient suspension wire coiled inside the
terminal housing to permit each electrode to be lowered
a maximum of one foot, with the exception of the lowest
electrode, which is the pump cut-out electrode with
suspension wire labeled “A”. The low electrode wire
marked “A” is already positioned near the bottom of the
1 ½” Electrode Housing and should not be lowered
further. This also applies to electrode wire mark A1 or
A2.
BELOW GRADE MOUNTING: When installing below
grade make electrical connections above grade. There
are 48 inches of suspension wire furnished past the
terminal housing for below grade mounting.
CAUTION
Do not allow the liquid leveling the basin to
submerge the terminal housing.

OPERATION
As the liquid level rises in the wet well, a hydrostatic
pressure on the flexible bulb is exerted. The hydrostatic
pressure tends to squeeze the bulb, causing a
displacement of its liquid. The displaced liquid rises in
the electrode housing toward the electrodes. The liquid
level within the electrode housing will always be equal to
the level of the liquid in which the controller is
submerged, since the density of both liquids are equal.
As the liquid within the electrode housing rises and falls,
it makes a and breaks electrical circuits with the
electrodes, thereby actuating the pump starters through
the controller relays.
CAUTION
This controller should not be used in liquids having a
temperature exceeding 140º F. or less than 35º F.
MAINTENANCE
The SEALTRODE r Series P Controller, if properly in-
stalled, requires little or no maintenance. It has no
moving parts, except for the control relays which should
be inspected semi-annually for worn or pitted contactors.
It is recommended that the operation of the controller be
observed for several complete operating cycles when
making routine maintenance and inspection of the pump.
REFILLING FLEXIBLE BULB: The electrolytic solution
within the control bulb should seldom, if ever, be
replenished because of evaporation. However, should it
become necessary to replenish the liquid within the bulb,
proceed in the following manner:
1. Refer to installation print showing the setting of the
electrodes.
2. Note the setting of the highest electrode and what
circuit it controls.
WARNING
Before attempting repairs to installation, disconnect the
power supply. Controls are automatic. This prevents
accidental running of pump motor. Starting motor during
repair activities could damage pump and may cause
personal injury.
3. Disconnect all electrical devices (pump starters) which
are not controlled by the highest electrode to prevent
their operation during the process of refilling the bulb.
4. Fill the basin to the highest electrode setting and then
slowly pour distilled water thru the tee. Fill the
connection until the high electrode circuit operates.
When the circuit operates, add an additional quart of
water.
5. In the event that the bulb has been over-filled, and
the pumps do not cut-off, remove and empty the bulb
and refill as outlined on page 3 under the heading “Filling
Flexible Bulb”.
LOCATING TROUBLE
IF THE PUMP FAILS TO START:
1. Make sure sodium bicarbonate has been added to
water.
2. Check the electrical service, making sure the current
characteristics are the same as that stamped on the
control box nameplate.
3. Check to see if the control wiring is in accordance with
the wiring diagram supplied with controller.
4. Determine if the electrical power at the control box
has been interrupted or disconnected.
5. Check set screw (14) and make certain it is right.
6. Short circuit the pump start electrode terminals in the
control box with a piece of insulated wire. This should be
done by a qualified electrician. If the pump operates
check the following:
a. Inspect the wiring from the terminals in the control
box to the controller terminal housing making sure that
all connections are clean and tight. Look for broken
wires.
b. Check the wire connections at the electrodes to
see if they are broken.
c. Check to see if the flexible bulb has been
damaged. If the bulb is damaged, liquid from the basin
may have entered the housing and coated the
electrodes with grease or oil. Grease and oil will
insulate the electrodes.
d. Check the bulb for loss of electrolytic solution.
e. Check the setting of the pump cut-in electrode. It
may be set too high.
f. Check for proper open venting of housing.
7. If the pump fails to operate after short circuiting the
electrode terminals in the control, check the following:
a. Check the ground wire, making sure that it is not
broken and terminal connections are clean and tight.
b. Check the control box for burned out transformer or
relay coils.
c. Check the relay contacts to see if they are corroded,
worn or pitted.
8. If the pump fails to cut off check the following:
a. Check the wire connections and insulation in the
terminal housing and control box, making sure they are
not forming a short circuit by being grounded to the box
or housing.
b. Check the electrodes, making sure they are properly
shielded. An electrode not properly shielded may form a
short circuit with the electrode housing.
c. Check the relay contacts in the control box to see if
they are stuck.
d. Too much liquid in the flexible bulb. Excessive liquid
in the bulb will keep the low pump cut-off electrode
submerged and the pump cut-in relay will not open.
