following locations are not proper for installation.
①
Vibrating places
②
The places with flammable vapors or particular gas.
③
The places under high temperature/humid
④

5-2.Connection to a vacuum pump
GCD series’ models only are adoptable for our oil rotary pump.
Additional set up is required when we adopt the other models. Please contact us for
further in detail.
Follow instructions at the previous page, P5 drawings and Section 6 for connecting to a
vacuum pump.
5-3. Oil and water separating element
If the element is soaked with water beforehand for 1 to 2 minutes, it helps form the water
separation membrane and improves its function at the operation outset. Always soak with
water before use.
To remove, refer to “10. Replacement of Elements.”
