INSTALL HIGH-PRESSURE C02 REGULATOR, C02 CYLINDER AND LINES
(FOR CARBONATED UNITS ONLY)
1. Install high-pressure C02 regulator, (S-101) on C02 cylinder using a new seal gasket.
MAKE SURE NEW WASHER IS INSIDE REGULATOR ASSEMBLIES COUPLING NUT
BEFORE CONNECTING TO CYLINDER.
WARNING-: To avoid personal injury and/or property damage, always secure C02
cylinder with safety chain to prevent cylinder from falling. It is recommended that
the C02 cylinder be installed away from heavily traveled areas such as doors,
passageways, corridors, etc.
2. Connect 1/4" inner braided plastic tubing from outlet of high-pressure C02 regulator,
(S-101), on C02 cylinder to Tee connection at low-pressure regulator, (S-221), using
prefabricated gas charging line, (S-105).
3. A line must be fabricated at this time. Cut inner braid tubing to size and install nipple,
(S-145), and nut, (S-150), to each end of tubing making sure either oetiker or ferrule is
previously installed on line. Secure these connections by use of proper tool. Connect
¼“, inner braid plastic tubing from outlet of tee at low-pressure regulator, (S-221),
(optional furnished with unit), to supplied line from unit marked gas.
INSTALL LOW-PRESSURE REGULATOR AND LINES (OPTIONAL)
1. Install low-pressure C02 regulator on the wall or another supporting structure in
general vicinity of cooling unit, C02 cylinder, B.I.B. rack or syrup tanks.
2. Connect 1/4" inner braided plastic tubing from outlets of low-pressure C02 regulator,
(S-221), to inlets of B.I.B. pump or syrup tanks.
