AIRLOCK
This pump is a centrifugal utility pump, designed to efficiently remove water.
However, it cannot move air. If air is trapped inside the pump (a condition called
“airlock”), the pump cannot pump water out even though the pump is completely
submerged. This pump has an anti-airlock hole. Air flows out through the
anti-airlock hole, eliminating the airlock so that the pump can operate properly. If
debris blocks the anti-airlock hole, unplug the pump, clean out the anti-airlock
hole, and restart the pump. Alternately, drain the water out of the garden hose,
keep the end of the hose out of the water, and plug in the power cord, restarting
the pump.
CAUTION: This hole is for anti-airlock purposes. Leakage of air or water is
NORMAL. DO NOT BLOCK THIS HOLE!
NON-SUBMERSIBLE TRANSFER PUMP INSTALLATION
WARNING: Always disconnect power source before attempting to install, service, or maintain the pump. Never handle a
pump with wet hands or when standing on wet or damp surface or in water. Fatal electrical shock could occur.
CAUTION: Always use the handle to lift the pump. Never use the power cord to lift the pump. To avoid skin burns, unplug
the pump and allow time for it to cool after periods of extended use.
The following picture shows a typical installation. Threaded adaptors are furnished for attaching garden hose where
conditions permit its use. The suction lift of this unit can get up to 8 feet. Be sure to use the suction hose and strainer with
built-in check valve included in the package.
