SAFETY ALERT SYMBOLS
Read and follow all safety information carefully. The signal words used in this manual are
selected as shown below and based on an assessment of the degree of potential injury or
damage (severe or minor) and the occurrence of injury (occurs or has the potential to occur)
when the warning is ignored:
DANGER!
Indicates a situation which, when not avoided, results in death or severe injury.
WARNING!
Indicates a situation which, when not avoided, has the potential to result in death or
severe injury; and/or severe property damage.
CAUTION!
Indicates a situation which, when not avoided, results in or has the potential to result
in minor injury; and/or minor property damage.
SAFETY PRECAUTIONS
Basic safety precautions should be followed, including the following:
Ensure all Local, State, and Federal Laws and Codes including health and safety guidelines are
met when installing Wellsys Equipment. Only qualified service technicians should attempt
installation and service of Wellsys Equipment. Always read the entire operating instructions
before using the appliance and save these instructions for future use.
DANGER! This product can cause death or severe injury if incorrectly operated, installed or
maintained. The installation, maintenance, sanitizing and any repair must be performed by
qualified persons trained by Wellsys International or their approved distributors only. Do not
remove any panel or cover to protect against electrical shock and exposure to UV radiation.
DANGER! ELECTRICAL SHOCK HAZARD. Always use a dedicated and properly grounded
outlet. Unit should be protected by ground-fault circuit interrupter (GFCI) or residual current
device (RCD) having a rated residual operating current not exceeding 30mA. Use only Wellsys
supplied power cord. Never use extension cords or power strips to connect unit. Do not use if
the power supply cord is damaged. Always unplug from power supply prior to servicing.
WARNING! AUTHORIZED USE ONLY. This appliance is to be used for its intended purpose as
described in this manual. Untrained individuals who use this manual assume the risk of any
resulting property damage or personal injury. This appliance can’t be used by children and
persons with reduced physical, sensory, or mental capabilities or lack of experience.
WARNING! UV-C EMITTER (UV LAMP). This appliance contains a UV-C emitter (UV Lamp).
UV-C radiation may, even in small doses, cause harm to the eyes and skin. Unintended use
may result in the escape of dangerous UV-C radiation. Never operate the UV-C emitter if
damaged or removed from enclosure. Do not touch or look directly into the emitter.

i16 Manual Page 5 - Revision: 2-09-2023
WARNING! DO NOT OPERATE IF DAMAGED. Unplug and isolate water supply if abnormal
conditions exist. Contact Wellsys or authorized dealer for repair, service, and installation to
avoid hazards.
WARNING! HOT WATER. Unit produces Hot Water in excess of 80oC (175oF). Water above
52oC (125oF) can cause severe burns or scalding. Keep unauthorized people and children
away from the unit to avoid accidental dispensing of hot water.
WARNING! CONNECT TO POTABLE WATER SUPPLY. This system is to be used for water only
and is NOT intended for use where water is microbiologically unsafe or with water of
unknown quality without adequate disinfection before or after the system.
WARNING! TIP HAZARD. Dispenser could tip or fall causing serious injury. Always install unit
on a firm, flat, and level surface and secure unit to cabinet, wall, or floor if needed. Never
place heavy items on top of unit and never climb, stand, or hang on unit or storage cabinet to
prevent injury and damage.
WARNING! UNIT IS HEAVY. TWO PERSON LIFT REQUIRED. Transport unit empty and always
use material handling equipment or two people with proper lifting technique to reduce injury
risk.
WARNING! STORE AND TRANSPORT UNIT EMPTY. ALWAYS SANITIZE BEFORE USE.
The unit must be completely drained before storing to avoid stagnation and reduce
microbiological contamination (potential bacterial growth). Always sanitize before use to
eliminate any potential microbiological contaminates.
CAUTION! INDOOR USE ONLY. Intended for Household Use. Never expose to direct
sunlight, heat sources, or ambient air temperature above 37°C (100°F) or below 2°C (35°F).
Install indoors and keep unit away from excessive humidity. Never expose to freezing
temperatures. Ensure there is adequate clearance around the unit to allow refrigeration
system condenser to dissipate heat. Warmer environments require more clearance around
the unit. Minimum clearance around all surfaces of the machine is 2-inches. Installs where
the ambient temperature exceeds 27°C (80°F), require a minimum of 4-inches clearance for
proper heat dissipation and efficient operation.
CAUTION! USE A WATER PRESSURE REGULATOR. Wellsys will not be responsible for injury
or damage caused by excessive water pressure. Input or feed pressure must be 40 psi to 60
psi. Be aware of any potential pressure surges caused by building/municipal pumping
stations.
CAUTION! USE UV STABILIZED SUPPLY LINES. Feed the unit with a potable ambient or
cold-water supply only. Feed water over 37°C (100°F) can damage the treatment
components. Water block devices and external leak detectors are strongly recommended.
Locate the unit as close to the water supply and the electrical connections as possible.
Immediately isolate or close water supply valve and contact service representative if leak is
noticed.
Contact Wellsys for assistance or help finding an Authorized Service Representative.

I16 FEATURES AND BENEFITS
Hot and Ambient Water and Ice
The i16 Water Treatment System comes standard with Hot and Ambient Water Selections to
meet a wide range of customer demands and makes and dispenses chewable ice.
Ice Storage and Water Capacity
The i16 Water Treatment System has 1.25 liters of Hot Water and can hold up to 16.5lbs of Ice.
Large Dispense Area with Recessed Faucet
11-inch dispense height with recessed faucet to protect from cross-contamination.
Leak Prevention
i16 Water Treatment Systems are supplied with a float valve to cut off the water supply in the
case of a water leak or overfill.
Hot Water Safety Function
The i16 Water Treatment System has a built in Hot Water Safety Function. To dispense hot
water, the user must press the hot water selection and then press the dispense button. This
prevents children and the elderly from being burned from hot water. In addition, if hot water is
selected, and not used within a short period of time, the product will automatically switch back
to the ambient water selection (the default selection).
ECO Mode
The i16 Water Treatment System has an Energy Saving Mode. Once the ice level is full, the unit
will automatically turn on ECO mode. The ECO mode save energy by stopping the ice making
operation (for a maximum of 6 hours). The machine can still be used to dispense ice and water
while ECO mode is active.
UV-C LED
Two UV-C LEDs are installed in the ice bin and ice melt area. They sanitize the ice and melt
water to provide more hygienic, cleaner ice.
Optional Base Cabinet
Available with an optional base cabinet to make free-standing.
Optional Hands-free Touchless Dispense Module
Available with an optional Touchless Dispense Module that uses Infrared Technology to activate
dispensing functions.
