KIT INSTRUCTIONS
Refer to FIGURE 1 for the following procedures.
1. The medium and low pressure regulator assembly must
be attached to the panel by two sheet metal screws
diagonally .
2. The air/C0
2 changeover valve assembly must be
positioned at the bottom of the panel with two sheet metal
screws horizontally .
3. The CO
2 changeover valve assembly for the CO2 tanks
1& 2 must be positioned on the left and slightly above the
air/CO
2 changeover valve assembly with two sheet met al
screws horizontally .
4. The low CO
2 alarm assembly must be positioned on the
upper left side and attached with two sheet metal screws
diagonally to expose the two mounting holes. The cover
must be removed to expose the two mounting holes.
5. Connect the medium and low pressure regulator
assembly to the air/C0
2 changeover valve assembly by
using the longer of the two 1/4" copper tube assemblies.
6. Connect the air/C0
