Basement Watchdog BWSS Series - Manual (Page 2)

• 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 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 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 HP pump with
the double float assembly are 8
Љ in
diameter and 14 Љ deep, for the 3/4 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 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) Hold 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, then insert
the pump plug into the receptacle on the
control box.
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 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.
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
Љ, 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.
