(1.4 BAR/6.2 BAR).
• Always use the water supply line supplied when
installing this appliance. Never reuse an old supply
line.
• Main supply CO

50 psi/80 psi (3.5 BAR/6.2 BAR).
• Minimum clearances must be maintained from all
walls and combustible materials.
• Keep equipment area clear of combustible
material.
Carbon Dioxide (CO2) displaces oxygen.
Exposure to a high concentration of CO
causes tremors, which are followed rapidly by
loss of consciousness and suffocation. If a CO
gas leak is suspected, particularly in a small area,
immediately ventilate the area before repairing
the leak. CO2 lines and pumps must not be
installed in an enclosed space. An enclosed
space can be a cooler or small room or closet.
This may include convenience stores with glass
door self serve coolers. If you suspect CO
build up in an area, venting of the B-I-B pumps
and / or CO2 monitors must be utilized.

Caution
GENERAL
All wiring must conform to local, state and
national codes.
MINIMUM CIRCUIT AMPACITY
The minimum circuit ampacity is used to help select
the wire size of the electrical supply. The wire size (or
gauge) is also dependent upon location, materials
used, length of run, etc., so it must be determined by a
trained & qualified electrician.
ELECTRICAL REQUIREMENTS
Refer to Model/Serial Plate for voltage/amperage
specifications.
Operate equipment only on the type of electricity
indicated on the specification plate.
