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! 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.

W9 Manual Page 5 - Revision: 10-06-2023
WARNING! TIP HAZARD. Dispenser could tip or fall causing serious injury if installed with a
base. Always install unit on a firm, flat, and level surface and secure unit to cabinet, wall, or
floor if needed and secure to the base, if applicable. 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 or rain. 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 80
psi. Be aware of any potential pressure surges caused by building/municipal pumping
stations. Failure to comply will void all warranties. The manufacturer accepts no liability for
damage caused by excessive water pressure.
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.
WARNING! REFRIGERANT SYSTEM. This system is manufactured with 134A refrigerant.
Repairs to the refrigeration system must be performed by a certified refrigeration technician
only.
CAUTION! DO NOT PLACE HEAVY ITEM OR WATER CONTAINER ON TOP OF UNIT. Water
may leak into the electrical system causing a fire hazard. Heavy items may fall off causing
injury.
Contact Wellsys for assistance or help finding an Authorized Service Representative.

CONTROL PANEL & OPERATING INSTRUCTIONS
•Hot Select Sensor: The left touch-free sensor is
used to select hot or cold water, activating it will
swap between the two options.
•Water Dispense Sensor
: The right touch-free sensor
can be activated to dispense water at the selected
temperature. (Default selection is cold water).
•Temp Selection Indicator: This LED indicator will
show the current selection of water temperature;
Hot or Cold.
•UV Enabled: This light indicates the units UV lights
are active and working properly.
•Call for Service: This light indicates the filters have
been exhausted and need replacement, or a
possible water supply issue.
•Drip Tray “Full” Indicator: This small float protrudes
from the drip tray grill if the water level rises too
high. An indication that the tray needs to be
emptied.

W9 Manual Page 12 - Revision: 10-06-2023
•Resetting Filter Life: Hold hand over HOT SELECT for 5 seconds until the service
indicator flashes. Pull hand away, then hold hands over BOTH the HOT SELECT and
DISPENSE sensors for 5 seconds until a multi-tone chime is heard.
•Changing the Dispense Rate: The flow rate on the W9CT is set to 3L/min, which is
twice as fast as traditional cooler and ideal for larger bottles. If it is deemed
appropriate to lower this flow rate, following these steps will reduce it to 2L/min.
Hold BOTH hands over HOT SELECT and DISPENSE sensors simultaneously for 5
seconds until a multi-tone chime is heard. Remove hands, then again place hands
in front of HOT SELECT and DISPENSE sensors and hold for 5 seconds until the
multi-tone chime is heard. Repeat the same sequence to switch back to 3L/min
flow rate.
•Silencing the Beep and Chime: The unit makes a Beep sound when a sensor is
activated. This sound can be turned off if desired by following the provided steps.
Hold hand over HOT SELECT for 1 second, then hold hand in front of DISPENSE
sensor 5 times in quick succession. The Beep sound should now be silenced. To
switch it back on, repeat this process.
