Installation and Service Manual

SAFETY

IMPORTANT SAFETY INSTRUCTIONS

Carefully read all safety messages in this manual. Learn how to operate the Chillz unit properly.
Do not allow anyone to operate the unit without proper training and keep it in proper working
condition. Unauthorized modifications to the Chillz unit may impair function and/or safety and
affect the life of the unit.

CARBON DIOXIDE WARNING

DANGER: Carbon Dioxide (CO2) displaces oxygen. Exposure to a high concentration of CO2 gas

causes tremors, which are followed rapidly by loss of consciousness and suffocation. If a CO2 gas leak
is suspected, particularly in a small area, immediately ventilate the area before repairing the leak. CO
lines and pumps should 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 CO2 may build up in an area, venting of the B-I-B pumps and / or CO2 monitors should be utilized.

QUALIFIED SERVICE PERSONNEL

WARNING: Only trained and certified electrical and plumbing technicians should service this unit.

All wiring and plumbing must conform to national and local codes.

2

SHIPPING, STORAGE, AND RELOCATION

CAUTION: Before shipping, storing, or relocating this unit, syrup systems must be sanitized. After

sanitizing, all liquids (sanitizing solution and water) must be purged from the unit. A freezing envi­ronment causes residual sanitizing solution or water remaining inside the unit to freeze, resulting
in damage to internal components.

ADDITIONAL WARNINGS

Installation and start-up of this equipment should be done by a qualified service technician. Operation,
maintenance, and cleaning information in this manual are provided for the user/operator of the equipment.

Save these instructions.

Installation and Service Manual

SAFETY

GROUNDING INSTRUCTIONS

WARNING: Risk of electrical shock. Connect to a properly grounded outlet only.

This appliance must be grounded. In the event of malfunction or breakdown, grounding provides
a path of least resistance for electric current to reduce the risk of electric shock. This appliance is
equipped with a cord having an equipment-grounding conductor and a grounding plug. The plug
must be plugged into an appropriate outlet that is properly installed and grounded in accordance
with all local codes and ordinances.

DANGER – Improper connection of the equipment-grounding conductor can result in a risk of
electric shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment grounding conductor. If repair or replacement of the cord or plug
is necessary, do not connect the equipment-grounding conductor to a live terminal. Check with a
qualified electrician or serviceman if the grounding instructions are not completely understood, or
if in doubt as to whether the appliance is properly grounded. Do not modify the plug provided with
the appliance – if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

WARNING – When using electric appliances, basic precautions should always be followed, in­cluding the following:

a) Read all the instructions before using the appliance.
b) To reduce he risk of injury, close supervision is necessary when an appliance is used

near children.
c) Do not contact moving parts.
d) Only use attachments recommended or sold by the manufacturer.
e) Do not use outdoors.
f) For a cord-connected appliance, the following shall be included:

• Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

• Unplug from outlet when not in use and before servicing or cleaning.

• Do not operate any appliance with a damaged cord or plug, or after the appliance

malfunctions or is dropped or damaged in any manner. Return appliance to the
nearest authorized service facility for examination, repair, or electrical or mechanical
adjustment.

g) For a permanently connected appliance – Turn the power switch to the off position

when the appliance is not in use and before servicing or cleaning.
h) For an appliance with a replaceable lamp – always unplug before replacing the lamp.

Replace the bulb with the same type.
i) For a grounded appliance – Connect to a properly grounded outlet only. See Grounding

Instructions.
