1DIUSE MANUAL
This manual:
•Familiarizes the user with the equipment.
•Explains installation and setup procedures.
•Provides basic programming information.
•Explains the various steps of operation.
•Gives specification information.
Read this manual first: Before you operate DiUse, read this manual to become familiar with the device.
Through this manual, special symbols will appear:
NOTE
Is used to emphasize information related with installation,
operation and maintenance without highlighting any
hazard.
WARNING!
Warning is used to indicate a hazard which could cause
injury or death if ignored.
CAUTION!

2LIABILITY AND WARRANTY
2.1 LIABILITY
Voltea will, under no circumstances be held liable for any consequential damages. The recipient hereby disclaims
all representations and warranties, whether expressed or implied with respect to materials and/or prototypes.
Including without limitation any warranties of non-infringement, merchantability or fitness for merchantability
or fitness for any particular purpose save that such shall have been prepared with reasonable skill and care. The
recipient accepts all risks which may be inherent in its use of materials and/or DiUse system and shall hold
harmless and indemnify each of Voltea and its affiliates officers, director, shareholders, employees and agents
from and against any and all claims, damage, losses or other liabilities that may arise directly and solely from
recipient’s use, storage, handling or disposal of the materials and/or systems.
2.2 WARRANTY
CapDI modules supplied with DiUse have been tested and have a guaranteed performance as they have passed
Voltea’s quality control test (a certificate of analysis will be supplied with each module upon request). Voltea
does warrant workmanship (leakage, connections) of the CapDI module for a period of 1 year from shipment
provided that the CapDI module is operated within the recommended operational limits as provided in the
section 4.2 and 4.3. Voltea does not warrant desalination and other performance aspects of the CapDI modules
within the customer application. Voltea warrants the DiUse for a period of 1 year from shipment provided that
the system is operated in accordance with this manual.
3VOLTEA CAPDI -MEMBRANE CAPACITIVE DEIONIZATION
The CapDI system uses Capacitive Deionization technology and its function is the removal of ions from the water.
NOTE: The CapDI system does not disinfect water.
CapDI: A tunable water deionization technology that is designed to remove dissolved salts from a variety of
water sources ranging from tap water and brackish groundwater to industrial process water. CapDI achieves this
at a lower economic cost and reduced environmental impact than any other available technology.

6
A CapDI module consists of a housing which contains multiple stacks of parallel unit cells. Each unit cell consists
of two porous carbon electrodes separated from each other by a spacer. On top of the electrodes, ion exchange
membranes are placed. The spacer between the membranes acts as a flow channel to transport the water to be
desalinated.
The water flows through a small electrical field of approximately 1.5 volts that is created over a pair of
electrodes. Dissolved ions are pulled out of the water stream, toward the electrodes. The electrodes are
separated from the water by the membranes that selectively allow only positive or negative ions to pass. CapDI
is effective at removing all type of ions from water (e.g. calcium, sodium, chloride, carbonate).
Uniquely: Our technology is environmentally friendly by its low energy consumption and minimal to no chemical
usage. Thus, allowing any unrecovered water to flow back into the ecosystem safely.
Scalable: Voltea’s technology treats water types ranging from residential consumer appliances to large-scale
industrial plants. Our systems are modular, allowing easy expansion to meet any increased water demands.
Tunable: CapDI is tunable, allowing adjustable TDS reduction between 25% - 95% depending on customer needs.
Eliminating the requirements for blending to achieve a specific water quality. The customer sets their desired
reduction rate and the CapDI maintains this level, continually adjusting itself to account for any fluctuations in
feed water characteristics.

4DIUSE
Voltea’s miniaturized version of the CapDI systems, specifically made for the point-of-use applications. DiUse
softens and desalinates brackish water for homes and businesses at an advantage to traditional desalination
technologies due to it being a salt-free, chemical-free alternative. DiUse is ideal for the HoReCa industry
alongside small households.
