CAUTION 
◇NEVER use any gas that is not specified as usable in this Manual. The use of such gas may corrode the STP pump and damage it.
◇A hazardous live voltage may exist at connector/terminal that marked 
. DO NOT touch the terminal. Doing so may result in electric shock.
When operating connection/disconnection to terminal, always power OFF the STP pump (Switch the breaker “OFF”).
◇Always check the STP pump has stopped, then turn OFF the primary power (switch the breaker “OFF”) before proceeding to any of the following operations. Failure to do so may cause the STP pump to rotate accidentally, which may injure operators seriously or result in electric shock.
Connect or disconnect cables;
Connect an external battery;
Perform maintenance and inspections such as replacement of the internal battery and/or fuses as well as inspections of deposit and/or the air cooling fan (when replacing fuses, always disconnect the internal battery connector);
Perform investigations into probable causes and action/measures taken in the event of occurrence of a problem; or
Open and close the STP control unit front panel (hereinafter referred to as the front panel) in order to check or reset the "BATTERY NG" (hereinafter referred to as "BATTERY NG") lamp.
◇The STP pump and the STP control unit are heavy products. Always use a crane or the like when lifting them. When lifting the STP pump by hands for unavoidable reasons, it must always be lifted by two or more people. Failure to do so may damage their hipbone or injure them due to occurrence of an accident such as fall.
◇Install the STP control unit not only by fitting it with the front panel fitting screws but also by supporting it from the bottom side. Fitting the STP control unit with the screws only cannot sustain its weight, and therefore resulting in product damage.
◇Always use the STP pump, STP control unit and STP connection cables of the same model name, serial number and cable length, which are specified on their own name plate. Failure to do so may result in product damage. If you use units with the same model name but different serial number and cable length; they must be adjusted. If the model names are different, they may not be used even when performing adjustment. In both cases, contact Seiko Instruments.
◇Use the STP connection cable and the motor connection cable that have a label affixed
.
The use of different cables may result in product damage.
◇Connect the cables securely. NEVER bend nor place heavy objects on the cable. Doing so may result in electric shock or product damage.
◇Always use the power voltage specified on the name plate for the primary power voltage of the STP control unit. Wire the power cable securely. Incorrect wiring may result in electric shock or product damage.
◇NEVER remove the splinter shield from the STP pump. Doing so may result in product damage.
