Product Warnings - Electrical
Product Warnings - Chemical
Product Caution
WARNING! Electric shock. The electrical equipment in this system must be
connected to a ground fault interrupting circuit. Failure to do so can cause elec-
trical shock resulting in severe personal injury or property damage.
WARNING! Electrocution. Never stand in water when handling electrical equip-
ment. Water is a conductor of electricity. Standing in water while operating this
equipment can cause electrical shock or electrocution resulting in severe per-
sonal injury.
WARNING! Electric Shock. Disconnect the main power before servicing any
electrical components. Failure to do so can cause electrical shock resulting in
personal injury.
WARNING! Severe personal injury. Chlorine tablets are harmful if swallowed.
Avoid contact with eyes, skin, and clothing. Wear protective gloves and eye
wear when handling the chlorine tablet. Keep chlorine tablets in tightly closed
container and away from heat, combustible materials, and hot surfaces. Wash
hands thoroughly after handling.
Precautionary Statements: Contact with skin or eyes may cause severe irrita-
tion or burns. Ingestion may cause severe burning to mouth, throat, and stom-
ach and may be fatal.
First Aid Procedures: If a chlorine tablet is swallowed, do not induce vomiting.
If conscious, give two glasses of water or milk. In case of contact with skin or
eyes, immediately flush with plenty of water for at least 15 minutes. In all cases,
contact a physician. Consult Safety Data Sheet for further health and safety
information.
CAUTION! Equipment damage. Follow all nationally and locally approved elec-
trical codes when installing this equipment. Failure to do so can result in equip-
ment damage.

Introduction 1
Introduction
The Geno RO/DI Water System is a dual water purification system producing Type 2 water (1 to 15 MΩ)
at a rate of 20 or 40 litres per hour. Type 2 water is stored in an external storage tank where it can be dis-
pensed as needed, or be connected to a distribution system.
All recorded data, warning messages, and dispensing information is displayed on a screen located on the
front panel of the unit.
All components of the system are assembled in a metal chassis and protected by a plastic housing that is
designed for bench or wall-mounting. The front panels are secured with magnets and can be removed for
easy access to consumables. The back panel is secured on the top and bottom with screws.
Geno Models
The content of this manual applies to these models. Some models include a submersible ultraviolet (UV)
light for sterilization.

2Introduction
Purification Process
In normal operation, feed water enters the system through the inlet solenoid valve (V3), engaging the
reverse osmosis pump (P1). the conductivity of the feed water is measured by the conductivity sensor (Q1)
before it reaches the pump.
The untreated water is pumped through the carbon-based pre-treatment module (TC001) to detain larger
particles greater than 20 micron in size and chemicals such as insecticides, pesticides, herbicides, and chlo-
rides. The pre-treatment module is essential to protecting the RO membrane and must be replaced at the
stated intervals to retain the integrity of the RO membrane as effectively and efficiently as possible.
After the pre-treatment module, water passes over the RO membrane (TC026). The RO membrane rejects
almost all bacteria, viruses, heavy metal compounds and organics, as well as removing 98 percent of the
salt content from the water. A percentage of the rejected water, referred to as concentrate, is sent to drain
through flow restrictor (R1), while the remaining water re-enters the loop to pass through the RO mem-
brane again, conserving water.
The product water, referred to as permeate, is measured through the permeate conductivity sensor (Q2) as it
leaves the membrane. If the water quality measure within the set limits, then the permeate solenoid valve
(V5) is opened and the permeate water reaches the next level of purification. If the water quality measure
is outside the set limits, the system will display a warning for the user to act accordingly and the permeate
is recycled or flushed to drain.
The accepted water is then pushed through the Endure Purification Pack 1 (TC002) which contains ion-
exchange resins. The de-ionization process occurs and the product water quality is measured by the post-
treatment conductivity sensor (Q3). If the quality above the set point, valve (V9) opens and the permeate
water is fed into the required external storage tank (TANK) where it is held as Type 2 water. It is recom-
mended that the tank is fitted with the submersible UV light (TC008) to maintain bacteria sterilization
while the water is stored.

•The permeate valve closes, the flush valve opens, and the system depressurizes for 30 seconds
as shown below.
6. When the pressure screen shown below appears, observe the pressure gauge to verify the system
has depressurized.
NOTE: The system does not measure the pressure, so it is essential that the user verify that there is
zero pressure before continuing.
7. When the system has been confirmed to be depressurized, touch . The flush valve closes.
