Cleaning

The surfaces of the ceramic stator and rotor inside 402’s valve are treated to give optimum airtight operation. If the valve has been used with alcohol based liquids, and then left unused for a while, a grinding noise may be heard during valve switching the next time the pump is used. This is because of friction between the ceramic surfaces. To correct this problem, you should disassemble the valve and clean the ceramic surfaces with a damp cloth.

Cleaning

Cleaning the Exterior

The instrument cover and front panel may be cleaned. Ensure that the instrument is switched OFF and the power cord is removed when you clean the instrument.

When you need to clean the instrument, use one of the three following methods:

1)A clean dry cloth.

2)A cloth dampened with water.

3)A cloth dampened with soapy water.

If a cloth dampened with soapy water is used to clean the instrument, only domestic soap may be used. No other form of detergent or chemical may be used.

Parts in the liquid flow path may be cleaned with ethanol or bleach (10 % Sodium Hypochlorite).

Cleaning the Valve

The valve must be cleaned after using the 402 with corrosive or hazardous liquids, if leakage has occurred, or if liquid flows back into the waste tubing, or if the dilutor has been left unused for a while after pumping alcohol based liquids. The valve must be dis-mounted from the 402 and separated from the syringe, then disassembled. The valve can then be cleaned or autoclaved. It is not necessary to autoclave the valve axle or the spring.

Dismounting the Valve

1)Disconnect all tubings from the valve.

2)Separate the syringe from the valve.

3)Undo the two screws securing the valve to the 402 front plate and remove the valve.

Disassembling the Valve

Hold the valve body firmly in one hand, undo the valve axle guide, using a 17 mm open ended spanner. Separate the axle guide from the body of the valve.
