12 Maintenance and Inspection

◇ Stop the STP pump, and turn OFF the primary power (Switch the

breaker "OFF"), before performing maintenance of the STP control

unit (battery replacement/fuse replacement).

Failure to do so may result in an accident such as electric shock.

◇ Stop the STP pump, and turn OFF the primary power (Switch the

breaker "OFF"), before performing inspections of the STP pump (for

deposit).

Failure to do so may result in the inadvertent rotation of the STP

pump, which may result in an accident.

◇ Power OFF the baking heater and the air cooling unit, before

performing maintenance or inspections.

◇ DO NOT touch any of the blocks, parts, or connectors inside the STP

control unit (excluding the battery connector). These parts are

excluded from maintenance or inspection.

12.1 Replacing the Internal Battery

The STP pump is equipped with rechargeable batteries for backup during a

power failure inside the STP control unit. In order to ensure that the battery

functions normally during a power failure, replace the batteries before the end of

their life (approx. one year).

See Section 9.4, "How to Replace the Internal Battery."

The "Battery Instruction Label" is affixed to the front panel. After replacing the

battery, always record the next replacement date.

12.2 Inspecting the Air Cooling Fan

In MANUAL OPERATION mode, turn ON the primary power (Switch the breaker

"ON"), and press the "POWER ON/OFF" switch on the front panel to switch it "ON."

Confirm that the air cooling fan in the rear panel of the STP control unit (See

Figure 4.2) is operating.

If the air cooling fan is not operating, contact Service office to replace it.

It is recommended to inspect the air cooling fan when replacing the battery.
