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 Pure Water Technology Equipment. Only qualified service technicians
should attempt installation and service of Pure Water Technology 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 Pure Water Technology 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 Pure
Water Technology 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 Pure Water Technology 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.

PW90CT Manual Page 5 - Revision: 7-6-2023
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 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. Pure Water Technology will not be
responsible for injury or damage caused by excessive water pressure. Input or feed pressure
must be 60 psi to 70 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 Pure Water Technology for assistance or help finding an Authorized Service
Representative.
