Page 4: Cautions For Safety
0.3 Cautions for safety Danger When toxic or flammable gases are exhausted from the pump, they may leak not only from the pump outlet but also from the pump unit itself. Take proper measures suitable for the type of gas. Danger After the pump has been used for exhausting toxic gasses, not only the pump itself but also vacuum pump oil (hereinafter called “pump oil”) get toxic. - Page 5 Warning Do not use the pump in an explosive atmosphere. Failure to do so will result in injury or fire. Warning Mount vacuum valve and leak valve between the vacuum chamber and pump. To stop the pump, always close vacuum valve and then open leak valve. If this procedure is neglected, the pump oil fills the cylinder, making restart difficult or causing damage to the pump.
- Page 6 Caution Fluoride rubber material is used for the internal parts of a pump. There are some for which the chemical resistance of Fluoride rubber material is not suitable. Especially, be careful of the following chemical. Ammonia, Acetone, Ethylene oxide, Ethylene diamine, Zinc acetate, Amyl acetate, Aluminum acetate, Isopropyl acetate, Ethyl acetate, Lead acetate, Calcium acetate, Cellosolve Acetate, Nickel acetate, Butyl acetate, Propyl acetate, Methyl acetate, Nitroethane, Nitropropane,...
