death. Do not handle a pump or pump motor with wet hands
or when standing on wet or damp surface, or in water.
Before attempting to check why a unit has stopped operating,
disconnect power from the unit.
1. The shaft seal depends on water for lubrication and cool-
ing. Do not operate the pump unless it is submerged in
water as seal may be damaged if allowed to run dry.
2. The pump will not remove all water. On a flat surface
Model No. R33SU will pump down to within 1/8" of the

AIRLOCKS
(FIGURE 2)
When a pump airlocks, it runs but does not move any water.
An airlock will cause the pump to overheat and fail. The pump
has a built in anti-airlock hole. See the exploded view on the
repair parts page 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.
