Important Safety Instructions
SAVE THESE I STRUCTIO S. This manual contains important SAFETY WARNINGS and
OPERATING INSTRUCTIONS for the Basement Watchdog pumps. You will need to refer to
it before attempting any installation or maintenance.
ALWAYS keep these instructions with the unit so that they will be easily accessible.
Failure to read and follow these warnings and instructions could result in property
damage, serious injury, or death.
•ALWAYS disconnect the pump from the power source before servicing or making
adjustments.
•EVER 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 GROU DED 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.
•EVER bypass grounding wires or remove the ground prong from the plug.
•DO OT 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.
•DO OT use the power cord or strain relief to carry the pump. Use the pump handle.
•DO OT expose the control unit to rain or snow.
•DO OT operate the pump or control unit if it has been damaged in any way.

The 3/4 P pump will accomodate a 2" discharge pipe. owever, most
homes have 1-1/2" pipes. Therefore we have included a 2" x 1-1/2"
reducer adapter with this pump. You may replace your 1-1/2" discharge
pipe with a 2" discharge pipe, and a 2" adapter to obtain the optimum
gallons per hour.

•When a check valve is used, a 1/8 in. (3.2mm) air bleed hole must be drilled
in the PVC pipe above the pump. Drill the hole at a 45° 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 z 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 Basement
Watchdog 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.
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 1/2 P pump with the double float
assembly are 8⬙in diameter and 14⬙
deep, for the 3/4 P 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 in. (3.2mm) air bleed hole must be
drilled in the PVC pipe above the pump. Drill the hole at a 45° 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.
(f) old the float switch against the discharge pipe so the cage is below the
bracket.
(g) Position the bottom of the float 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.
(h) Lower the pump into the sump by the handle.
(i) To avoid debris pouring into the float, it should be positioned on the side of the
discharge pipe opposite the drain tile. Note: It is desirable to mount the float
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
Dual Float Controller
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.
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 p mp activates, it sho ld have
a “normal p mping” so nd. Any abnormal so nd, vibration, or lack of o tp t is the
signal of a problem. Stop the p mp and refer to the tro bleshooting g ide.

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.
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
mo nting the float switch, position the bottom of the cage
at the height yo want the p mp to activate.
Dual Float Controller
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.
Operating the Pump in a Continuous
Duty Application
The Basement Watchdog 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 the use of the controller. The outlet must be a single phase properly
grounded 3-prong receptacle, 115V, 60 Z (preferably with ground fault circuit
interrupt). For contin o s d ty operation, the p mp m st be s bmerged at least 3/4 of
the depth of the p mp at all times.
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.
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.
Backup Installation
When the power goes out, the Basement Watchdog AC sump pumps will not operate.
For protection during a power outage, a Basement Watchdog battery backup system
can be installed. There are three systems with matching batteries that will provide
protection. The illustration below is an example of a typical battery backup
installation.
