Model Nos. 2300, 2305, and 2310 will pump down
to within 1/8" of the pumping surface. Model No.
2355 will pump down to within 5/8" of the pumping
surface.
NOTICE: For long cycle times, the pump must be
submerged to prevent the motor from overheating. A
fully submerged pump is preferred for proper cooling
when a pump runs for a long time.
AIRLOCKS
When a pump airlocks, it runs but does not move any
water. An airlock will cause the pump to overheat and fail.
The pumps have a built in anti-airlock hole. See Figure 1
for the location of the hole. Water leakage from the anti-
airlock hole is normal.
If you suspect an airlock, unplug the pump, clean out the
anti-airlock hole with a paper clip or a piece of wire, and
restart the pump.
