Any modification will void the warranty and may result in potential hazard. We are not responsible for any injury or damage caused by any non-intended purposes and modifying the instrument without authorization.

1. Check the voltage specified on the name plate and ensure it matches the line voltage in your location.
2. Install the instrument in a clean, dust-less and ventilated area under 40°C.
3. Never use the instrument with any corrosive, chemical, flammable gas or toxic material.
4. Please connect the instrument with high-pressure hose or tubes.
5. The Prote^TM filter cartridge can prevent a large amount of liquid from overflowing into the pump. Please ensure the liquid in the moisture trap not exceed safety level.
6. To ensure proper function of the Prote^TM protection device, the pump must be installing on a flat level surface and should not be moved when operation. If the buoy closes during operation, it must be manually reset by uninstalling and reinstalling the filter cartridge.
7. The filter cartridge is used to absorb moisture and block dust. Please replace the cartridge to maintain pumping efficiency when it becomes dirty or color-changing.
8. The instrument is not designed to start against applied vacuum / pressure. To prevent damage, verify that the inlet and outlet are at atmospheric pressure before each start. If necessary, the inlet (and outlet of Rocker 430) can be vented to atmosphere by partially unscrewing the regulator knob.
9. This instrument has a thermal protection device that automatically shuts-off when it becomes overheated.
10. The temperature of the instrument surface is very high after use or during work, please don't touch it to avoid being burnt.
11. The instrument must not be used to create vacuum and pressure simultaneously.
12. Do not use any lubricant, which may damage the instrument.

Operation

• Operation

1. Press power switch (1) to activate the instrument after making sure all tubing are well-connected.

• cold trap or trap bottle is recommended to connect before air inlet (4) of vacuum pump, while amount of moisture and steam exists.
• A hoop holder is available to fix filtration apparatus securely and save space.

2. To setup vacuum by adjusting the vacuum regulator (8).
   Pressure can also be set up on Rocker 430 by adjusting the pressure regulator (12).

• Pilot 100, vacuum controller (Cat. No. 183100-01(02)) is available for precise vacuum control.

3. Check liquid level of moisture trap (7) daily and drain the liquid when it is up to the neck of the bottle.

1. When pump is used for aqueous solution filtration, please ensure the liquid level of flask not exceed safety level. Failure to comply could result in serious damage to the pump and void the warranty. If it occurs, please contact the distributor immediately for service.
2. While Rocker 430 is operated as a compressor, please ensure a 20-min break while every 30-min working period to prevent the instrument shutdown from overheating.

Maintenance

1. Please remove the liquid in the moisture trap after every use and keep pumping the air for at least 2 minutes to withdraw the residual steam.
2. If the liquid in moisture trap is more than 70%, please stop the experiment immediately to empty the liquid.
3. The instrument is not autoclavable. Please clean the surface by pure water or 75% ethanol.
4. Please replace the cartridge to maintain pumping efficiency when it becomes dirty or color-changing.
5. Valve plate(s), O-ring(s) and silicone tube(s) are consumables, it is recommended to replace it on a yearly basis or as needed to ensure good operation.

• How to reset the Prote^TM protection device

1. Remove the moisture trap (7) and filter cartridge (6) by rotating clockwise.
2. Disassemble the filter cartridge (6) to ensure the buoy is not closed.
3. Reinstall all components, filter cartridge and moisture trap back.

• How to replace cartridge

1. Please replace the cartridge when it becomes dirty or color-changing.
