CAUTION

  •  Do not use the pump for pumping liquids other than plain water, such as 

oil, salt water, or organic solvents.

 

•  Use with a power supply voltage variation within ± 10% of the rated voltage.

 

•  Use the pump at the water temperature of between 0 and 40°C.

   

•  Failure to observe these precautions could cause the pump to malfunction, 

which may lead to current leakage or electrical shock.

 

Critical Use Pressure

CAUTION

   Do not operate the pump in an area that is exposed to a water pressure that 

exceeds the values given below.

 Pre-Installation Check

Using a megger, measure the resistance between the tip of 

the cabtyre cable plug and the ground pole (using alligator 

clips) to verify the insulation resistance of the motor.

Note:

 

The insulation resistance reference value of 20 MΩ minimum is based on a new or repaired 

pump. For reference values of a pump that has already been put into operation, refer to "7. 

Maintenance and Inspection" in this manual.

Note:

 To use the pump for a special solution, contact the dealer where the pump was purchased, 

or the Tsurumi sales office in your area.

Insulation resistance reference value 

= 20M Ω minimum

 Precautions During Installation

WARNING

  When installing the pump, be mindful of the pump's center of gravity and 

weight. If the pump is not suspended properly, the pump may fall and break, 

which may lead to injury.

CAUTION

  When installing or moving the pump, do not suspend the pump by the 

cabtyre cable. Doing so will damage the cable, which may cause a current 

leakage, electrical shock, or fire.

Refer to the installation examples illustrated below and pay attention to the points 

described below to install the pump.
