Installation and Service Manual
SAFETY
IMPORTANT SAFETY INSTRUCTIONS
Carefully read all safety messages in this manual. Learn how to operate the unit properly. Do not
allow anyone to operate the unit without proper training and keep it in proper working condition.
Unauthorized modifications may impair function and/or safety and affect the life of the unit.
NSF CERTIFICATION
For the revised Product to be considered certified, the certified field modification Flavor Magic shall be used only
on the following certified products: Manitowoc Beverage Equipment, Servend Models MD-150, MD-175, MD-200,
MD-250, MDH-302, MDH-402, SV-150, SV-175, SV-200 and SV-250.
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.

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.

SAFETY
GROUNDING IN STRUCTIONS
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 Ground-
ing Instructions.
