Safety Warnings
Models ST1033 & ST1050
WARNING
• ALWAYS disconnect the pump from the power source before servicing or making
adjustments.
• NEVER handle the pump or motor with wet hands or when standing on a wet or damp
surface while the pump is plugged into the power source.
• MAKE SURE THERE IS A PROPERLY GROUNDED RECEPTACLE AVAILABLE. This pump is
wired with a 3-prong grounded plug. To reduce the risk of electric shock, be certain that
it is only connected to a properly grounded, 3-prong receptacle (preferably with ground
fault circuit interrupt). If you have a 2-prong receptacle, have a licensed electrician
replace it with a 3-prong receptacle according to local codes and ordinances.
• NEVER bypass grounding wires or remove the ground prong from the plug.
• DO NOT use an extension cord. The electrical outlet should be within the length of the
pump’s power cord, and at least 4 feet above the floor level to minimize potential
hazards from flood conditions.
• DO protect the electrical cord from sharp objects, hot surfaces, oil, and chemicals. Avoid
kinking the cord.
• MAKE SURE the supply circuit has a fuse or circuit breaker rated to handle the power
requirements noted on the nameplate of the pump.
CAUTION
• DO NOT use the power cord or strain relief to carry the pump. Use the pump handle.
• DO NOT expose the control unit to rain or snow.
• DO NOT operate the pump or control unit if it has been damaged in any way.
• DO NOT use sump pumps in pits handling raw sewage, salt water, or hazardous liquids.
• DO NOT disassemble the pump or control unit. When service is required, contact
Glentronics technical support at 800-991-0466, option 3. Return the product to the
manufacturer for any repairs at the following address:

NOTICES
• When a check valve is used, a 1/8” (3.2mm) air bleed hole must be drilled in
the PVC pipe above the pump. Drill the hole at a 45º angle toward the bottom
of the sump to avoid splashing water outside the sump pit. Make sure the hole
is above the water line, and below the check valve. If a hole is not drilled
above the pump, an air lock may prevent the pump from operating.
• The control unit must receive 115V AC +/- 5% and 60 Hz from the AC outlet.
• These primary pumps will not provide protection during a power outage. With the
risk of property damage from high water levels, the addition of a Pro Series battery
backup sump pump system is highly recommended.
• After the initial installation, be sure to check the operation by filling the sump
with water and observing the pump operation through one full cycle.
• For continuous duty operation, the pump must be submerged at least 3/4 of the
depth of the pump at all times.
• In instances where the discharge line is exposed to freezing temperatures, the pipe
must be sloped downward so any remaining water will drain out. Failure to do so
will prevent water from exiting the sump and damage the pump if the line freezes.
Installation Instructions
Prior to Installation
1. Visually inspect your pump. Products may be damaged during shipping. If the
product has been damaged, contact your place of purchase or Glentronics, Inc.
before installation.
2. Thoroughly read the instructions provided to learn specific details regarding
installation and use. This manual should be retained for future reference.
WARNING
1. Use a pit that conforms to all local codes
and is large enough to accommodate the
pump and float switch. The minimum
requirements for the 1/3 HP pump with the
double float assembly are 8⬙ in diameter and
14⬙ deep, for the 1/2 HP pump they are 10"
in diameter and 16" deep. However, larger
sump pits are preferred, since they will
extend the discharge cycle and reduce the
number of times the pump turns on.
2. Clean the pit of all debris. The pump’s
strainer must be kept clear.
3. The pump should not be set directly onto a
clay, earthen, or sand base. You may install
bricks or blocks under the pump to provide
a solid base.
4. The pump should be level.
5. Install discharge plumbing according to
local, regional and state codes. Rigid PVC
pipe is recommended.
6. An in-line check valve is recommended to
prevent back-flow. This check valve is
mandatory when sharing a discharge line
with another pump (i.e. a back-up pump or
a second primary pump).
(a)
When a check valve is used, a 1/8” (3.2mm) air bleed hole must be drilled in
the PVC pipe above the pump. Drill the hole at a 45º angle toward the
bottom of the sump to avoid splashing water outside the sump pit. Make sure
the hole is above the water line, and below the check valve. If a hole is not
drilled above the pump, an air lock may prevent the pump from operating.
7. Install a gate valve or ball valve if required by any codes.
8. The pipe must be positioned in a downward slope so any remaining water will drain
away. Failure to do this will prevent water from exiting the
pit and damage the pump if the line freezes.
9. If you are replacing an old sump pump:
(a) Unplug the pump from the outlet.
(b) Loosen the check valve or rubber union by unscrewing
the bottom hose clamp. (If the existing system is
installed without a check valve or rubber union, saw
the pipe apart above the sump pit.)
(c) Remove the old pump and unscrew the pipe and adapter.
(d) If the adapter fits into the new pump, screw the pipe into the pump. If not,
cut a piece of rigid PVC pipe and connect it to the new adapter by cleaning and
cementing the two pieces together. (Follow the instructions on the PVC cleaner
and cement.)
(e) Loosen the enclosed stainless steel hose clamp by turning the screw
counterclockwise and slip it over the pipe on top of the pump.
This installation must be in accordance with the National
Electric Code and all applicable local codes and ordinances.
9B
9C
(f) Hold the float switch against the discharge pipe so the cage or sensor rod is below
the bracket.
(g) Position the bottom of the float or sensor rod at the height you want the pump to
activate and turn the screw clockwise to tighten the hose clamp, but do not
tighten it completely at this time. If installing the ultimate sensor, be sure to
place the drive mechanism of the clamp on the opposite side of the sensor. This
will allow the extra material of the clamp to be as close as possible to the sensor
once it is completely tightened.
(h) Lower the pump into the sump by the handle.
(i) To avoid debris pouring onto the float or sensor, it should be positioned on the side of
the discharge pipe opposite the drain tile. Note: It is desirable to mount the float or
sensor below the drain tile that empties into the pit. Mounting it above the drain tile
would allow water to fill the drain tile before the pump is activated. (See diagram).
(j) Once the switch is in the desired position, tighten the hose clamp.
(k) Connect the pipe on the pump to the existing discharge pipe with a rubber union
or check valve and tighten the hose clamps securely.

Connecting the Pump and Controller
WARNING
Dual Float Controller (DFC1)
Plug the control box into a properly
grounded, 3-prong receptacle (preferably
with ground fault circuit interrupt), then
insert the pump plug into the receptacle on
the control box. You should provide
additional protection for the control unit by
using a surge protector.
For a neater installation, secure the power
cord and the float switch cord to the
discharge pipe with wire ties or hose
clamps. Keep the cords separated from
each other on opposite sides of the pipe.
Deluxe Dual Float or Ultimate Solid
State Controller
1. Mount the controller to the wall
through the 2 holes on the cabinet
using the proper mounting hardware
for the application. The controller
should be mounted at least 4⬘ from
the floor and within 4’ of the outlet.
2. Open the plastic door on the top of
the unit and using a flat head
screwdriver adjust the dial to select
the number of seconds that the
pump will run after the water falls
below the sensor. The timer can be
adjusted from 5-45 seconds. The manufacturer default is about 10 seconds.
Install a 9V alkaline battery and replace the plastic door.
3. Plug the control box into a properly grounded, 3-prong receptacle (preferably
with ground fault circuit interrupt). Then, plug the pump into the receptacle
on the control box. Do not use an extension cord.
4. Make sure the Power Failure Alarm slide switch is in the ON position.
Completing the Installation
1. After the initial installation, be sure to check the pump operation by filling the sump
with water and observing the pump through one full cycle. The pump should run for
10 seconds after the lower float drops. Note: When the pump activates, it should have
a “normal pumping” sound. Any abnormal sound, vibration, or lack of output is the
signal of a problem. Stop the pump and refer to the troubleshooting guide.
2. Replace the pit cover making sure not to pinch or crimp the pump wire with the
cover. The pit cover either has a ‘hole punch’ that will allow the cord to be passed
through or one can be drilled in the cover.
Make sure the outlet is single phase, 115V and 60HZ
for all the pump installations.

Product Operation
Dual Float Switch
The dual float switch contains two large floating rings
enclosed within a protective cage. Water will lift the
bottom float by a 1⁄4⬙, which will activate the pump. If
for any reason the lower float does not activate the
pump, the water will rise and activate the second switch.
As the pump evacuates the water from the pit the floats
will drop. The pump will run for an additional 10 seconds
to extend the cycle after the lower float drops. Note:
When mounting the float switch, position the bottom of
the cage at the height you want the pump to activate.
Dual Float Controller (DFC1)
The Dual Float Controller will activate the pump when
either float is lifted, and then shuts off automatically 10
seconds after the float drops. Plug the pump cord into the
piggyback switch on the control unit.
Ultimate Sensor
The “Ultimate Sensor” uses a unique, patented, smart sensor
that has no moving floats. A single 3.5” corrosion proof,
stainless steel, sensor rod will detect virtually any liquid. It’s
imbedded smart sensing software adjusts to the harshest
conditions regardless of any accumulated coating. The 10’ sensor
wire includes a connector that can be separated from the
controller when the wire needs to be threaded through small
openings in sump pit covers.
The Deluxe Dual Float Controller (DFC2)
The PHCC Pro Series Deluxe Dual Float Controller features a
series of warnings (audible and visual) that pinpoint potential problems with the
pump, switch and power conditions. The controller will sound an alarm when power
has been interrupted, when the pump has run for more than 10 minutes continuously, or when the 9V battery is low. The 9V battery (sold separately) runs the
controller during a power outage, allowing it to sound an alarm if the circuit breaker
trips, the controller is not plugged in securely, or the home’s power is interrupted.
Note: The 9V battery will only power the switch, not the pump. The Deluxe Controller
has a dial (located in the battery compartment) to adjust the
number of seconds that the pump will run after the float drops.
The Deluxe Controller will also run the pump once a week for
approximately four (4) seconds. This test will exercise the
pump and help ensure the pump is working properly.
The Ultimate Solid State Controller (USC3)
In addition to having all of the features as the Deluxe Dual Float
Controller, the Ultimate Solid State Controller has a monitoring
feature that will sound an alarm if the controller detects a weak
signal or has lost the signal from the sensor. The solid state
circuitry of the controller also has no moving parts which make it
the best choice for high cycling applications.
Operating the Pump in a Continuous Duty Application
The Pro Series pumps are rated for continuous duty and may be used in applications
requiring continuous pumping including fountains, ponds, etc. For use in any continuous
duty application the pump should be plugged directly into the wall outlet without
of the controller. The outlet must be a single phase properly grounded 3-prong receptacle,
115V, 60HZ (preferably with ground fault circuit interrupt). For continuous duty operation,
the pump must be submerged at least 3/4 of the depth of the pump at all times.
Understanding the Warnings & Alarms Deluxe and Ultimate Controllers
AC power is out
There are several causes for power failure.
The most common causes are a power
outage by the electric company or a
tripped circuit breaker. Although the
deluxe controller can not run the pump, it
will sound an alarm indicating the loss of
power. This will allow the homeowner to
address the problem.
If this warning light and alarm are on, the
control box is not receiving AC power for
one of many reasons:
1. The control box is not plugged in
2. The power to the house is out
3. The circuit breaker to that outlet has been tripped
4. The ground fault interrupter on that outlet has been tripped
5. A power brownout is taking place

Power Failure Alarm slide switch
When the controller is not receiving AC power, the monitoring features and the
audible alarms are powered by the 9-volt battery. This type of battery will power
the controller for many hours, but not indefinitely. Once the source of the AC
power alarm is determined, it is suggested that the Power Failure Alarm slide
switch be turned to the OFF position until the power is restored. This will preserve
the battery and silence the alarm. When AC power is restored, slide this switch
back to the ON position. Note: If the AC power is restored and the slide switch is in
the OFF position, the alarm and light for the 9-volt battery warning will activate,
even if the battery is good. This is a reminder to reset the alarm. Slide the switch
to the ON position. If the battery is good, the light will go out. If the alarm
continues to sound, replace the battery.
The system is operating
This light should be ON and flashing at all times. It is included to indicate that
the system is monitoring the sump conditions. This light will not illuminate when:
1. The power is out and the Power Failure Alarm slide switch is in the OFF
position
2. The power is out and the 9V battery is discharged
3. The controller is not functioning. Contact the Glentronics service department
The 9-volt battery low or slide switch is OFF
1. The 9-volt battery located in the top of the control box is coming to the end of
its useful life. Replace it with a new 9-volt alkaline battery.
2. The Power Failure Alarm switch is in the OFF position. It must be in the ON
position at all times, except when silencing an actual power failure condition.
Pump, float or sensor problem
This key feature monitors the time that the float switch (or sensor rod) is up
continuously or in the activated position. It is unusual for a pump run for 10 or
more minutes continuously. This can occur for many different reasons. Either the
float is stuck in the up position, there is a mechanical problem with the pump, or
there is a problem with the plumbing connections. Please refer to the
Troubleshooting Guide on the back.
Controller has lost signal from sensor (USC3)
This alarm will sound if the controller has detected a weak signal or has lost the
signal from the sensor. Check for a secure connection between controller and
sensor wire or clean the sensor rod.
Maintenance Check List
Maintenance should be performed 1-2 times per year.
1. Remove all debris from the bottom of the pit.
2. Remove all debris floating in the water.
3. Remove all debris from the float switch cage
or clean the sensor rod.
4. Fill the pit with water. Make sure pump turns on at the intended level.
5. While the pump is running, make sure pump is evacuating water at a good pace.
6. While the pump is running, make sure a stream of water is escaping from the air
bleed hole. If not, clear the hole of any deposits or debris.
Backup
Installation
When the power goes
out, the Pro Series AC
sump pumps will not
operate. For protection
during a power outage,
a Pro Series battery
backup system can be
installed. There are
three systems with
matching batteries that
will provide protection.
The illustration at right
is an example of a
typical battery backup
installation.
