CAUTIONS AFTER USE
1. After use, always make sure to disconnect the power plug and lift the pump out of the water.
The insulation will degrade and it will cause an electric shock or an electric leakage.
2. If the pump is used in water containing a large quantity of sand or heavy filth, and it is left
standing after being stopped, the sand, etc. will remain inside the pump.
Before storing the pump, wash the inside thoroughly and dry it completely.
REPAIR AND INSPECTION
1. Check insulation resistance
Check the resistance of the insulation regularly.
Use a tester to measure the resistance between the ground wire and the power cord.
• 20 MΩ or more: Normal
• 1-20 MΩ: Sufficient to operate the pump but the power cord and motor should be
inspected as soon as possible.
• 1 MΩ or less: Abnormal. Conduct inspection and repair.
2. Replacing the paraffin
The shaft seal whitch is the pump's most important water tight component is sealed with
liquid paraffin.
Inspect the liquid paraffin every 1,000 hours (or every 3 months).
If the liquid paraffin gets impure when removed, or if water is mixed into it, the seal assembly
(mechanical seals, etc.) needs to be replaced.
(The amount of liquid paraffin in the seal is 280 cc.)
