GAS AND ELECTRICAL INSTALLATION
At the outlet of the gas tank, a model 10-080 high pressure regulator must be installed, with a pressure gauge
in order to verify the correct supply pressure. The pipe used for the connection is 3/4”of diameter,
either L-type copper or 40-gauge black tubing.
The length of the pipe should not exceed 10 meters, from the outlet of the gas tank. A union nut must be installed
between the stopcock and the low-pressure regulator. Before the machine’s gas input, a low pressure regulator
must be installed.
Verify that the electrical connection is 220v. No short circuits, no loose or bare wires.
