WARNING
Risk of electric shock. This pump is supplied with a grounding conductor
and grounding-type attachment plug. To reduce risk of electrical shock, connect
only to a properly grounded, grounding-type receptacle.
TO REDUCE THE RISK OF ELECTRIC SHOCK, INSTALL ONLY ON A CIRCUIT
PROTECTED BY A GROUND-FAULT CIRCUIT-INTERRUPTER (GFCI).

INSTALLATION AND USE
• An acceptable motor-control switch shall be provided at the time of installation.
• Thermally protected
1. This pump works under an automatic surface control
system whereby it is automatically switched
on and off by a float switch.
2. The pump starts automatically when the water level rises
and the float comes up to the ON water level, and stops
automatically when the water level falls and the float
comes down to the OFF water level.
3. The ON and OFF water levels can be adjusted by
loosening the cord band bolt. However, the length
of the cord between the cord band and the float
switch should be between 50 mm and 150 mm,
otherwise the float switch will not operate normally.
4. The float switch should be installed where it does
not come into contact with walls or is any other
obstructions.
5. The pump should not be installed where water is
discharged directly onto the float.
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.
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 110 V AC or
220 V AC, 50 Hz.
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
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.

MAINTENANCE AND INSPECTION
1. Periodically check the insulated condition with a megger tester.
To be acceptable, the resistance between the earthing wire and the power cord
should be 100 Megohm and higher.
2. The shaft of the water-tight mechanism as the most critical part 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 230 cc 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 lower side of the pump body.
