OPERATION / MAINTENANCE
Risk of electrical shock. Can burn or cause
death.
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 operat-
ing, 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 sub-
merged in at least 5” of water as the seal may be
damaged if allowed to run dry.
2. The motor is equipped with an automatic reset ther-
mal 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 automati-
cally and restart the motor. If the protector trips
repeatedly, the pump should be removed and
checked as to cause of difficulty. Low voltage, long
extension cords, clogged impeller, very low head or
lift, etc., could cause cycling.
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.
Float Switch Tether Length, Models 2990 and 2995.
NOTICE:
Do not change the tether length of the float
switch. The float must be able to swing through its com-
plete arc without interference.
