1. Remove the blocker at gas outlet port that was in place during gas filling process.
2. Connect the gas outlet port to your desired application, e.g. to the inlet of the supply valve of a fuel cell
system.
3. Open the On/Off manual valve by turning it anti-clockwise slowly until the end. Gas from inside the carbon
fiber cylinder will now flow out through the gas outlet port.
4. To turn off the gas at the end of usage, shut off the On/Off manual valve by turning it clockwise.
3.3 USING THE FILLED CARBON FIBER CYLINDER
CHAPTER 3 | OPERATING PROCEDURES
The MGPR can be used as a lab bench-top equipment without being connected to a carbon fiber cylinder.
1. The low regulated output pressure at the gas outlet port is always open. Put a blocker to prevent gas from
coming out.
2. The On/Off manual valve serves to open or close the connection between your Hydrogen source which
enters the MGPR through the refueling port and the carbon fiber cylinder which is connected at the carbon
fiber cylinder plug. If you are not going to use a carbon fiber cylinder, make sure that the On/Off manual
valve is turned OFF (fully clockwise).
Caution: unregulated high pressure gas will gush out from the carbon
fiber cylinder plug if the On/Off manual valve is not fully turned OFF.
3. Turn on your Hydrogen gas supply. Hydrogen gas will now flow through the refueling hose and enter the
MGPR through the refueling port.
4. Remove the blocker from the gas outlet port
.
Regulated low pressure Hydrogen gas will now come out
from the gas outlet port and can be channeled to your desired application, e.g. to the inlet of the supply
valve of a fuel cell system.
5. To turn off the gas at the end of usage, shut off your Hydrogen source directly.
Reminder: the On/Off
manual valve on the MGPR is not in use in this configuration and shall be fully OFF (clockwise) at all times.
