Precautions for use
• Be careful not to drop the pump onto the
fl
oor. A strong
impact may reduce pump performance. Do not use a pump
which has once damaged. Otherwise an electrical leak or
shock may result.
• The pump is a light water-/dust-proof structure of IP66, but
is not totally waterproof. Do not have the pump wet with the
liquid handled or rainwater.
• Never wet the pump head, control unit and drive unit. Oth-
erwise, Failure or an accident may result. Immediately wipe
off liquid if the pump has got wet.
• Do not close the discharge line during operation. Other-
wise, liquid may leak or tubing may break.
• Remove the control unit only when necessary. Note that an
applicable control unit differs with each drive unit. Do not at-
tach a control unit to an inapplicable drive unit. Otherwise, an
electrical circuit or the drive unit may fail.
• Release the pressure from the discharge line before disman-
tling the pump or removing tubing. Otherwise, chemical liquid
gushes out.
• Be careful not to come in contact with residual liquid.
• Do not clean the pump or nameplate with a solvent such
as benzene and thinner. This may discolour the pump or
erase printing. Use a dry cloth or a wet cloth with water or
neutral detergent.
