1.3.3 Control of gas pressure (only for poles without pressure gauge / Pressure switch)
1. Close metering pressure valve
2. Connect metering pressure gauge to pole.
3. Read pressure compensation for temperature as shown on page 14. If reading
Is between 2.0 and 2.5 disconnect gauge.
4. Disconnect the operating device by disconnecting the voltage to the motor
and operate by hand “close” and “open”.
5. Close cylinder reducer valve.
6. Close charging valve.
7. Open cylinder main valve, and note reading on gauge (should show approx.
70 bar for full cylinder).
8. Open the reducer valve until a reading of 2.5 bar pressure is registered.
(If the reading is too high, close reducer valve and release gas by opening
charging valve with hose disconnected).
9. Open charging valve a little so that the gas leaks a little, thereby emptying
Hose of any air.
10. With the use of the snap connection, connect the hose to the metering tube.
11. Open the metering pressure valve.
