NOTE
The following procedure applies for both nitrous oxide and oxygen gases:
a. Turn on gas cylinders by rotating the valve stem on the cylinder counter-clockwise slowly two full
rotations. Use customer-supplied cylinder wrench or use wrench available through your
MATRX by Parker dealer.
b. Examine reading on pressure gauges located on regulators. For a full tank of oxygen, the
pressure should be about 2000 PSIG. For a full tank of nitrous oxide, the pressure should be
about 750 PSIG.
c. The regulators are factory set to 50-55 PSIG. If you think the output pressure is outside this
range, adjust the regulator output pressure by the following steps 1-5.
1. Install a low pressure gauge capable of monitoring 50-55 PSIG into the low pressure outlet of
the regulator. This may be accomplished as shown below:
