Frequently Asked Questions - RODIA-VAC ROTHENBERGER
What type of oil should I use with the Rothenberger RODIA-VAC pump?
Use only high-quality vacuum pump oil with low vapor pressure. For this RODIA-VAC model, a mineral-based oil designed for refrigeration service is recommended. Change the oil when it becomes cloudy or dark.
How often should I change the vacuum pump oil?
Change the oil after every evacuation job if possible, or at least when the oil turns milky or dirty. Regular oil changes prevent moisture and contaminants from damaging the pump and keep the ultimate vacuum performance at its best.
Can I operate the RODIA-VAC without a filter dryer?
It is not recommended. The pump is protected by an inlet filter and an anti-backflow valve. Operating without a filter or with a clogged filter can let debris into the pump and reduce its efficiency. Replace the filter regularly and ensure the suction line is clean.
What is the ultimate vacuum of the RODIA-VAC?
The two-stage design allows the pump to achieve a final vacuum of 20 microns (0.02 mbar) when the pump is running with fresh clean oil and the system is sealed. This is suitable for deep dehydration of refrigeration circuits.
How do I connect the RODIA-VAC to a refrigeration system?
Use a standard 1/4" or 3/8" SAE flare connector. The pump is provided with both inlet sizes. Connect the pump via a vacuum hose to the service valve, open the valve, and start the pump. Make sure all other valves are closed to avoid moisture ingress.
Does the RODIA-VAC have a gas ballast valve?
Yes, the RODIA-VAC features an adjustable gas ballast valve. It is used during the initial part of evacuation to help prevent water vapor from condensing in the pump. Close the gas ballast once the vacuum is deep for final evacuation.
What is the pumping speed of this vacuum pump?
The RODIA-VAC pumps about 50 litres per minute (2.2 CFM). This makes it a good choice for small to medium air conditioning and refrigeration systems, such as split-type units and small heat pumps.
How should I store the RODIA-VAC after use?
After use, seal the inlet and outlet openings to protect the pump from dust. Run the pump for a few minutes with the gas ballast open to purge any moisture. Store the pump in a horizontal position in a clean, dry place. Always keep the oil clean.
Is the pump equipped with overload protection?
Yes, the motor has an internal thermal overload protector. If the pump gets too hot or a locked rotor is detected, the power is automatically cut off to prevent damage. After cooling, the pump can be restarted.
What maintenance does the RODIA-VAC require?
Maintain the oil level and change oil regularly, clean or replace the inlet air filter, check the hoses and connectors for leaks, and occasionally inspect the gas ballast valve. With proper maintenance, the pump will provide many years of reliable service.
