Operation
Operation
Electrical shock hazard . Can burn or kill. Do
not handle a pump or pump motor with wet hands or
when standing on a wet or damp surface, or in water.
Before attempting to check why unit has stopped
operating, disconnect power from unit.
Risk of fire and explosion . Can cause severe
injury, property damage or death. Do not use in
explosive atmospheres. Pump water only with this pump.
1. The shaft seal depends on water for lubrication
and cooling. Do not operate the pump unless it is
submerged in water as the seal may be damaged if
allowed to run dry.
2. The motor is equipped with an automatic reset
thermal protector. If the temperature in the motor
should rise unduly, the switch will cut off all power
before damage can be done to the motor. When the
motor has cooled sufficiently, the switch will reset
automatically and restart the motor. If the protector
trips repeatedly, the pump should be removed
and checked as to cause of difficulty. Low voltage,
clogged impeller, very low head or lift, etc., could
cause cycling. Do not use extension cords.
3. The pump will not remove all water. If a manually
operated pump is operating and suddenly no water
comes out of the discharge hose, shut the unit off
immediately. The water level is probably very low
and the unit has broken prime.

Figure 1 – Float Switch Tether Length
NOTICE: Do not change the tether length of the float
switch (see Figure 1). The float must be able to swing
through its complete arc without interference.
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 built-in anti-airlock hole. See Repair
Parts for the location of the hole. 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.
