300 NL/minute (Zone 1 and Div 1), or a continuous flow rate of at least 142 NL/minute
(Zone 2 and Div 2). It is good practice to allow for at least 30% additional gas volume.
The supply pipe work and associated valves must be sized to deliver the appropriate
amount of gas during the purging phase of operation, and maintain more than the
minimum supply pressure, 90 PSIG (6 bar) or 60 PSIG (4 bar), at the input to the purge
system during purging. Prior to connecting the gas supply to the purge and
pressurization system, flush the supply pipe work with clean gas to remove any debris
that may have been introduced into the pipe work during installation. Refer to figures
1 through 6.
Note: The air supply temperature must not exceed 40°C (104°F).
Sample Gas Supply
The sample gas supply connected to the unit must not exceed 20 PSIG (1.36 bar) at
any time. It is the responsibility of the user to ensure that if a pressure limitation facility
is used, then it shall comply with the requirements of 2014/34/EU or other applicable
national or local standards, and that proper assessment of fault condition has been
applied. Failure to do so may invalidate the certification of this product.
