The Lavit Cold Beverage Dispenser
The Lavit Beverage Dispenser is designed to dispense either cold still water, cold sparkling water,
or a Lavit beverage, which can be made with either still water or sparkling water, depending on
the beverage type. When selecting a Lavit beverage using sparkling water, the beverage can be
crafted using a choice of carbonation levels: soft, medium, or full.
The Lavit Cold Beverage Capsule
The Lavit beverage capsule and top lidding are made from aluminum and
are fully recyclable without any additional processing. Each capsule is
designed to be a single use mixing chamber for the beverage selection. This
approach eliminates all possible beverage cross contamination.
Cold Mix Chamber
The primary function of the Lavit Beverage Dispenser is to make cold, flavored, and healthy
drinks. The mix chamber is designed to receive a Lavit beverage capsule, crack and peel the top
lidding, introduce a mix stream, and process and merge the beverage stream with a still or
sparkling water finishing stream. The key components of the mix chamber include the blue
capsule tray where a capsule is placed, the silicone water nozzle for the mix and finishing streams,
and the entire capsule carriage which tilts forward to dispense the mixed beverage into the
finishing stream. The carriage begins and ends it cycling at the HOME POSITION.
Cold Tanks
The cold still water tank has a storage capacity of 1.3 gallon (5 liter) of cold water and is made
from 304 stainless steel. Sparkling water is made in a secondary 0.26-gallon (1 liter) capacity
tank made from 304 stainless steel. The sparkling water tank sits inside the cold still water tank
in a unique tank in tank system. The whole assembly is made cold by a fully immersed direct chill
evaporator. The cold-water temperature is microprocessor controlled, is non --- adjustable, and is
factory set at 37.4F (3C)
Filter and CO2 Cylinder Side Compartment
The door on the right side of the dispenser provides access to the filter and CO2 cylinder
compartment. The recommended Lavit ECO3 filter or a Lavit Bottled Water pump is mounted
towards the front of the compartment. Connection points for both are molded in the compartment
side wall. The CO2 pressure regulator and gas cylinder are mounted towards the rear of the
compartment.

6
Rear Panel
The rear panel on the Lavit Dispenser has the following features:
CO2 Purge –the toggle on the upper left (from the front of the unit) allows CO2 gas to be
purged from the system. Purging is required on the initial set up and at any time gas
pressure is to be released from the unit.
Power Socket –the supplied power cord attaches into the power socket on the lower right.
Power Switch –the power switch is used to power on or power off the unit.
Water Inlet –a quick connect ¼” fitting for the inlet water line. When initially installing
the water, line push the line in a second time when water pressure is applied to ensure
a complete seal.
Water Drain –the drain on the lower left of the panel is used to drain down the 5-liter
cold water tank. The drain plug is secured with a screw. To remove the drain plug rotate it
90 degrees to the left.
Microprocessor Control and Touchscreen
The Lavit Dispenser is a microprocessor-controlled beverage and water dispenser with a LCD
touch screen providing the user an operating interface and to display process information. The
microprocessor controls temperature, water filling, water levels, capsule mixing, water finishing
streams, operating of the mix chamber, and dispenser status. The touchscreen will default to the
HOME SCREEN when the unit is ready to dispense water or a beverage.
ANY SCREEN (OTHER THAN THE HOME SCREEN) CAN BE EXITED AT ANY TIME BY PRESSING
THE BACK ARROW ON THE UPPER LEFT OF THE DISPLAYED SCREEN.

Service Screen and Date/Time Settings
The date and time set up screen and the service menu can be easily accessed by pressing the gear icon in
the lower left of the Home Screen. After setting the date and time the service menu can be
accessed by pressing the SERVICE SET UP icon. USE THE PASSWORD TO ENTER THE SERVICE
MENU IS 8888.
From the Service Menu the technician can set the ozone on time, the allowed Max Temp for
beverage and water dispensing, enabling or disabling Sleep Mode and the Filter Timer, and
entering a Water Set Up Screen. The Pod ID setting is currently non --- active for future use.
Lavit Button
The black Lavit button MUST BE PUSHED TO DISPENSE WATER OR A BEVERAGE. The use of a
final dispense button allows the user to verify their drink selection and ensure a cup is placed
under the dispense point prior to dispensing.
The button has a halo ring which changes color based upon the dispenser status. The halo colors
are:
Blue halo= Stand by. Unit will dispense cold still water when pressed.
Green halo = Ready to dispense after menu selections are complete.
Flashing green = Dispensing. PRESSING THE BUTTON WHILE FLASHING GREEN
TERMINATES THE DISPENSE AND SENDS THE BEVERAGE CARRIAGE TO HOME
POSITION.
Red Halo = Waiting for selections to be completed.
Flashing red halo = Fault condition. REFER TO TOUCHSCREEN GRAPHIC.

8
Disinfection
The cold tank water system is disinfected every 24 hours at 3 am (factory setting). The Ozone
Generator will turn on for 1 hour and as the generator runs, ozone is injected into the cold tank by
means of the cold tank circulation pump. This ensures that the entire content of the cold tank is
exposed to ozone every 24 hours. The ozone start time can be changed as required through the
service screen.
Filtration for POU installation
Lavit recommends using the Lavit ECO3 Filter for dispenser installations to a building’s main
water supply (POU). The filter is a 0.5-micron carbon block rated at 1500 gallons, and is NSF
certified to standard 42 Classes 1, chlorine taste and odor, and standard 53 cysts, lead and
asbestos. The Lavit ECO3 also has a NSF certified multi-layer sediment particulate membrane to
protect the carbon block. In any known high sediment water areas please use a pre --- sediment filter
before the machine and filter.
Antimicrobial Protection
The contact parts of the Lavit Dispenser are protected by Lavit through silver ion technology. A
silver ion additive is added to the raw plastic parts as they are manufactured. This inhibits the
growth of bacteria on contact surfaces. The additive will not leach out and will be effective for the
life of the machine.
Bottled Water Installation
In addition to a POU installation, the Lavit Dispenser is designed to also work with a 5 --- gallon
bottle water supply. A bottled water installation will require the fitting of a Lavit bottle water
pump kit, which is supplied separately.
Transporting the Lavit Dispenser
The Lavit Unit should not be transported with water in either tank or with a CO2 cylinder attached.
Please drain the unit of all water per the instructions provided in this manual before moving the
unit. The CO2 cylinder should also be removed and the CO2 regulator secured in place with tape.
CO2 Cylinders
CO2 cylinders are provided to distributors and dealers by authorized Lavit distributors. Each filled
cylinder contains 1.5 pounds of liquid CO2 which when released to atmosphere converts to a gas.
Sparkling water is created by mixing CO2 gas in cold chilled water. Each cylinder is filled with food
grade or beverage grade CO2. It is imperative that a minimum of food grade gas is provided. It is
critical that distributors and dealers and their service personnel properly handle, store, and
transport filled cylinders.

CO2 Cylinder Handling
1. DO NOT expose filled Lavit CO2 cylinders to temperatures above
120°F (49°C) or below 34°F (1°C). If exposed to heat for aperiod of
time the safety pressure seal on the cylinder will burst and may
cause injury if the cylinder is in close proximity to thetechnician.
2. DO NOT wash the Lavit CO2 bottles in the dishwasher and DO NOT
rinse the bottle in hot water. DO NOT place the bottles in the
freezer. Doing so will compromise the integrity of thecarbonating
bottle material and may result in serious personalinjury.
3. DO NOT use any CO2 bottle not specifically designed to work with
the Lavit dispenser. Use only a LAVIT labeled cylinder providedby
an authorized Lavit Cylinder Distributor.
4. The Lavit CO2 cylinder should be properly installed prior to
operating the Lavit dispenser.
5. The CO2 cylinder should be inspected prior to use for any dents,
punctures, or other damage. If any are detected, DO NOT use the
CO2 bottle and contact your cylinderprovider.
6. Mishandling the Lavit CO2 cylinder can result in serious personal
injury. Always keep CO2 bottle away from any heat source and out
of direct sunlight. Do not store or leave filled cylinders in aservice
van for long periods of time especially when experiencing warm
weather.
7. Do not transport the Lavit Dispenser with the CO2 cylinder
connected.
