AIRLOCKS:
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail.
This pump has a small hole in the side of the pump housing.
See Figure 1. This is an anti-airlock valve. If you suspect an air-
lock, insert a hat pin or a pipe cleaner into the anti-airlock hole
to clean out the debris.
To Replace the Vertical Float Switch:
NOTICE: The float must be able to complete its entire cycle
without interference from any object.
1. Mount the bracket on the switch housing with the bracket
mounting screws. See Figure 2.
Make sure the pin holds the float rod in the
switch housing; otherwise the pump will not shut off.
NOTICE: Pull gently on the rod to make sure the pin holds the
float rod in the switch housing.
2. Mount the switch assembly on the pump with the screw
provided.
3. Run the pump through one complete cycle to verify switch
operation is correct and that nothing interferes with the
switch’s operation.
