Parker Porter Nitronox Plus Quick Start Manual

1. Pre-Check
Note: To perform these tests, gas supply cylinders or gas supply shutoff valves are required in order to isolate the
gas supply form the device. Attempting to perform these tests with central pipeline supplied gas without a
local shut off mechanism is not recommended.
WARNING: Proper inspection and maintenance of this device is essential to prevent gas leaks. All
hoses, fittings, and connections should be inspected regularly, and all leaks should be repaired
immediately.
WARNING: If precheck test cannot be executed successfully, do not use this device and contact
distributor.

If either pressure has dropped below 40 psi, check
the demand valve to ensure the quick-connect

the delivery port. Inspect all hoses and connections
for leaks; if any hoses are leaking, ensure the
