MAINTENANCE AND TROUBLESHOOTING
(CONTINUED)
5. Periodic cleaning of pump is required to maintain performance
of the pump. Follow the cleaning steps listed below:
a. Unplug the power cord.
b. Remove the four (4) base screws (Figure 2).
c. Remove the base and impeller plate.
d. Remove the debris and make sure the impeller turns freely.
e. Reinstall impeller plate, base, and screws.
6. Check the priming hole for obstruction. (Figure 2).
Follow the cleaning steps listed below:
a. Unplug the power cord.
b. Remove the four (4) base screws (Figure 2).
c. Remove the base and impeller plate.
d. Use a pin or paperclip to clean the priming hole and air
escape channel.
e. Reinstall impeller plate, base and screws.
7. If pump runs continuously, unplug the unit. Once unplugged,
check for debris stuck inside the sensor body (Figure 3).
Remove any trapped leaves, debris or dirt.
8. If the pump cycles on and off too often the electronic switch
may need cleaning. Unplug the pump and turn upside down.
The sensor probe will be visible inside the switch housing.
Clean inside the housing by gently scrubbing with a small brush
and using soapy water.
Do not use pump if any part of the switch
housing or probe is cracked, broken or missing.
PUMPING HEIGHT
When water is pumped to an elevated position, any volume that
has not reached the discharge outlet can flow back through the
pump when the pump shuts off. This back-flow can cause the
water level in small areas to rise enough to re-start the pump. A
check valve [Check Valve Sold Separately: RIDGID CAT No. 40138]
is required in this situation. For proper operation, make certain the
check valve is oriented as instructed.
In small areas a check valve is required to prevent
backfl ow. Without a check valve the pump may
cycle continuously and potentially wear out the pump components.
