Ther mally protected
INSTRUCTIONS FOR USE
1. Please check the type, aperture, output, frequency, and voltage indicated
on the name plate attached to the upper part of the pump.
Pay close attention, in particular, to frequency and voltage as inadequate
frequency and voltage can cause lower pump performance and troubles.
2. Place to use
The pump can be used at almost all places but avoid continuous short-water
operation at a sandy place, as such may accelerate wear of the pump.
Try to install the pump at a position where water can be collected most easily.
When the pump in installed on soft muddy or sandy ground, lay wooden
board or block under the body to prevent setting down. Strictly refrain from
putting into any pond bath, or swimming pool in which anybody is staying.
3. Hose piping
When any hose is used for connection, keep the hose as straight as
possible as excessively bent hose reduces water quantity.
Refrain from placing the discharge port under water Inverse flow may
sometimes be resulted due to siphon effect when the operation is
stopped.
4. Cabtire cable
To transfer the pump or to install, hold the pump on the handle or a rope
tied to the handle. If the cabtire cable is pulled instead of the rope, the
core wires may sometimes be cut off. To extend the cable, use a cable of
the same or larger size than the one attached to the pump. Strictly refrain
from placing the joint between the main line and the extension in water.
5. Earth leakage breaker
Be sure to ground the earthing wire before connecting the cabtire cable
to the power source. The green wire is for earthing. Be sure to attach the
leakage breaker to prevent any possible leakage trouble.

CAUTION
1. Leak Current Breaker
For home use, attach a leak current breaker, GFCI (offered separately)
to ensure safety.
2. Connect the power source
Absolutely refrain from connecting this pump to any other power source
than 110V AC, 50Hz.
3. Water to use
Absolutely refrain from using the pump for any oil, sea water,
*
strong alkaline or strong acidic solution, or any agricultural chemicals.
4. Do not run dry!
Idling can cause trouble, to prevent short cycling place pump at deepest
position as possible.
5. Handling of power cord (cabtype cable)
a. Never lift or move pump by power cord.
Only lift by handle or tie rope supplied to handle.
b. Select and use proper size extension cord.
Do not run extension cord in water.
6. Using in bath, etc.
Do not enter the water when pump is being used.
CAUTION
The pump is used a double mechanical seal.

6. After use
If the pump is left as it is after used for water of high sand content or
other special substances, the sand is accumulated in the pump and will
affect the next operation. Before stopping operation, therefore, be sure to
keep pumping supernatant water or clean water for some time to clean
out the inside.
7. Thermal protector
The pump incorporates a thermal protector to protect the motor, and the
motor is stopped automatically at a over-load operation due to any reason.
When the motor stops automatically, be sure to check after turning
off the power source.
AFTER USING PUMP
1. In cold climates, do not allow pump to freeze.
Remove pump from water to prevent damage due to freezing.
2. Completely drain and dry pump of water before storing.
MAINTENANCE AND INSPECTION
1. Periodically check the insulated condition with a insulation resistance tester.
To be acceptable, the resistance between the ear thing wire and the
power cord should be 100Meg ohm and higher
2. The shaft of the water-tight mechanism as the most critical par t of the
pump is sealed with liquid paraffin. The life changes greatly depending on
the operating condition but the quantity should be checked periodically.
Use 170cc of Crystol No.70 by Exxon Mobil Corporation for the sealing.
The liquid paraffin can be checked easily by removing the hexagon
socket head bolt at a side of the pump body.
