Run a drain line from the evaporator
coil drain to the pump. Use the flexible
plastic pipe where the code permits.
Insert the pipe 1" below the pump
cover. Do not install inlet drain line that
would interfere with operation of floats.
Connect outlet tubing (copper or vinyl)
to discharge on pump. Do not run
tubing vertical more than is
recommended by the lift on each unit.
For good flow, slant the horizontal run
downward toward the drain. Each CB25
comes standard with a check valve for
connecting to 3/8" O.D. copper tubing.
Each CB50 unit comes standard with a
check valve for connecting to ½" O.D.
copper tubing. A copper tube adapter is
included for vinyl hose hook-up.
Turn the electric power off at the fuse box before making any line voltage connections.

DIAGRAM
FOR CB25
AND CB50.
To test safety float switch, temporarily stop flow of discharge line by sharply bending vinyl tubing. Pour more water into pump
inlet. Water level will rise beyond high level of control float until safety float switch breaks the "Y" thermostat circuit shutting down
air conditioner condensing unit. Unbend the tube and the pump will empty the entire sump. Replace inlet line into pump inlet.
MAINTENANCE AND TROUBLE SHOOTING
1.
Remove dirt that may collect in bottom sump.
2.
Look at vinyl DISCHARGE LINE to see that it is open and water can pass through freely.
3.
Always replace cover to keep electrical parts clear of dust and grime.
4.
See item 7 of Introduction.
