Basement Watchdog Greenline BW Series - Manual (Page 2)

• The Basement Watchdog BW1033 and BW1050 come equipped with a built-in
air relief valve located on the top of the pump. While the pump is active,
some water may come out of the valve. This is normal. The valve is needed to
prevent an air lock within the pump. DO NOT obstruct the air relief valve or an
air lock may prevent the pump from activating.
• 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
pumps with the double float assembly
are 7
Љ in diameter and 14Љ 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).
7. Install a gate valve or ball valve if required by any codes.
8. In instances where the discharge line is exposed to freezing temperatures, 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 a 1-1/2” PVC adapter by
cementing the two pieces together.
(Follow the instructions on the PVC cleaner and cement.) Then screw the new
piece into the pump.
(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, some
water may come out of the air relief valve located on the top of the pump. This is
normal. The pump should have a “normal pumping” sound. Any abnormal sound,
vibration, or lack of output from the discharge pipe 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.
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.
