Precautions
•
The vacuum pump should not be used to remove acid or alkaline solutions or corrosive
gases. Such substances will cause the pump's fixed scroll, orbiting scroll, and other parts to
be corroded and shorten the lifespan of the pump. The vacuum pump can be used in
applications where organic solvents need to be removed. If the pumping medium contains
water vapor or liquid water, it may adversely affect the pump's throughput and lengthen the
time needed to attain an acceptable level of vacuum.
•
The vacuum pump uses PTFE material for the tip seal on the compression chamber. It is
normal for a small amount of PTFE powder to be present in the exhaust during pumping.
Therefore, it is strongly recommended that no exhaust silencer or muffling system be used
at the pump's outlet. If a filter-type silencer must be installed due to noise, it is
recommended that the filter be cleaned regularly and replaced every six months. The
silencer may cause the exhaust pressure of the pump to rise due to the air resistance and
shorten the lifespan of the pump.
•
The vacuum pump is not suitable for removing substance which contains a large amount of
powder. The composition, size, and content of the powder will affect how well the pump
works. Please contact the service department first before purchasing to confirm that the
vacuum pump is suitable for your application if a large amount of power needs to be
pumped.
•
If the pump has been unused for more than 3 days, or the customer needs to
pump the chamber to below 5 Pa, it is recommended that the pump be first run for 20
minutes with no loading (open the air inlet first and vent for 1-2 minutes).
•
If a small amount of liquid water or water vapor gets into the pump, it will affect the pumping
rate and increase the amount of time to achieve vacuum. It is recommended that the pump
run with the gas ballast open for about 20 minutes to remove any water from the pump.
•
The vacuum pump should not be operated with an open inlet port for any significant time.
