2.2 Inspection
■
Daily inspection
Always check for abnormality in vibration, noise, current value, and
discharge capacity. Stop operation on sensing abnormality. And solve
problems on the trouble shooting section.
■
Cleaning
Periodically flush the inside of a supply tank and piping with water
to keep clean conditions.
Turn off power before cleaning the pump exterior. Wait until the
pump cools down if it is right after operation. Wet a cloth with tap
water and wring it out for cleaning the pump. Use a neutral detergent
for greasy dirt and then rub with a dry cloth.
Check the pump exterior is dried before a restart.
CAUTION
Do not clean the pump with solvents such as benzine, alcohol and
thinner. This may discolour the pump.
CAUTION
Risk of electrical shock or short circuit. Do not wet a motor or
electrical wiring.

Wear parts
To run the pump for a long period, wear parts such as an impeller and
an O ring need to be replaced periodically.
Contact your distributor for detail.
