Read Before Use
Your HIDREX tap water iontophoresis device is designed to maximize
functionality and usability. System setup is easy, and the device is simple to
operate. However, the following safety instructions and legal regulations must
be observed and strictly adhered to. To ensure the proper, safe and long-term
functioning of your HIDREX iontophoresis device, the following maintenance,
care and disinfection instructions must be performed regularly.
Please read this information carefully!
Your Safety Is Important
iThis treatment system may only be powered by the HIDREX AC power
adapter (which can be identified by a HIDREX nameplate with Serial-
No.). This power supply is especially designed for this device.
iA change of the therapy device is not allowed. Do not open the device.
This therapy device has no controls inside. All service work is only to be
carried out by HIDREX GmbH.
iTo prevent burns during treatment, make sure the supplied plastic nets or
pads always cover the treatment electrodes. Avoid direct contact with the
metallic surface.
iSeveral devices may not be simultaneously used by one patient.
iPrior to treatment, remove any metallic jewelry (wedding bands, etc.)
which would otherwise be in touch with the water source (trays or pads).
Keeping such accessories on would lead to localized minor (electrical)
burns that are secondary to increased current densities.
iAvoid application of more current as can be safely and comfortably
tolerated by the patient. Always treat carefully and observe patient
reaction.
(As a rule, avoid current intensity greater than 0,2mA/cm2of active electrode area.)
iUse only genuine accessories approved by HIDREX for use with your
device. Other unapproved accessories may result in unforeseen and
dangerous behavior of your device.
Please follow the instructions for your accessories, as well.
iThe long-term effects of chronic electrical stimulation have not been
established.
iKeep the device out of the reach of children and do not leave children
unattended during therapy! There is a risk of strangulation due to the
enclosed cables.
iDo not turn the device off during the therapy. In most cases this causes a
safe but uncomfortable electric shock1.
1These shocks are unpleasant, but absolute safe.

Who Is The Therapy Suitable For? - Contraindications
In principle, the therapy is suitable for all persons from the age of 4 years. The
prerequisite for this is that the therapy is carried out under the supervision of
an adult.
From the age of 12, it is up to the legal guardians to decide whether the therapy
can also be carried out without supervision.
Regardless of age, therapy must always be performed under the supervision
of an adult if the patient is unable to understand the instruction manual and act
according to the instructions contained therein (e.g. cognitive impairment).
Users with the following conditions are considered having contraindications for
iontophoresis, so treatment should not be administered unless otherwise
directed by your physician:
iwith a cardiac pacemaker or ICD (implantable cardioverter/ defibrillator)
iin pregnancy
iwith a metal-containing intrauterine device (IUD)
iwith any metal object within the electric current path
·The electrical current path is considered as the shortest point through the body
between the two electrodes. For example, the current path for a person treating
hands would be from one hand in the tray with an electrode, up the arm, across the
chest, down the other arm and hand to the other electrode.
·This means that a user that has a metal screw in their leg or knee can do hand
treatments, but not foot treatments
iwith piercings in the contact area, which cannot be removed
ithat have within the treatment area any large skin defects / wounds (too
large to cover with petroleum jelly), potentially malignant lesions, acute
localized infections, skin eruptions, or swollen, broken, or inflamed areas
ithat have within the treatment area any impaired or absent sensation
(e.g. patients with polyneuropathies)
iApply electrical current through or across the brain, or sinuses (increased
risk of ventricular fibrillation)
iwith suspected or diagnosed heart problems or epilepsy
Side Effects
The following side effects or effects may occur for a short time after the
therapy session on the treated skin areas:
iMild dysesthesia (tingling or burning)
iShort-term skin irritation (reddening) after treatment
iErythema (skin redness, transient vesicles or blisters)
iSkin irritation or burns at the areas of electrode contact have been
reported with the use of electrical stimulators

User Manual 2019-06-06, Rev.: 1.0
5
Additional Important Safety Considerations
iPlace the treatment device on a firm level surface
iMake sure that the treatment device is at room temperature before you
power it up
iThe system should not be operated near shortwave or microwave devices.
A minimum distance of 2 meters should always be kept
iPrior to using AC wall power, check that your outlet meets the system’s
requirements of 100-240 V~ and 50-60 Hz
iUnplug the AC power adapter if a thunderstorm approaches or if you do
not intend to use the treatment system for a longer time
iThis treatment device should only be used indoors. Do not expose the
system to rain or excessive moisture
iPrior to cleaning the system, turn the device off and unplug all connectors.
For cleaning, use a soft cloth moistened with a mild cleaning agent
iDo not use kerosene, thinner, alcohol, wax remover or other solvents
iPrevent kinking of the cable and do not expose the cable to heat or
chemicals. If the cable is damaged, unplug it from the device and have it
checked by an authorized HIDREX repair center
iDo not perform iontophoresis therapy in parallel with aluminum-containing
antiperspirants in the same treatment area.
iSimultaneous connection of the patient to a ME unit for high-frequency
surgery can result in burns under the electrode surfaces of the stimulation
current unit and damage to the stimulation current unit.
Intended Use / Mechanism Of Action
Intended Use:
This tap water iontophoresis device is intended to treat Hyperhidrosis
(excessive sweating) affecting hands, feet, face, back/ neck and
underarms.
Any other use or usage beyond this scope is considered unintended
use and may have dangerous consequences.
Mechanism of Action:
During the HIDREX treatment, a current flow through the body regions that
are being treated. The water in the trays or pads mediates this current flow.
The skin areas in contact with the water will thereby secrete less sweat.
Although treatment success has been validated in numerous medical
studies, there is still no completely satisfactory scientific explanation for the
mechanism of action. Medical researchers believe that the electrical current
irritates the synapses between sweat-inducing nerves and sweat glands to

6
2019-06-06, Rev.: 1.0 User Manual
such an extent that sweat glands can no longer be stimulated. In other
words: the treatment does not affect the sweat glands directly, it only affects
the nervous input to these glands.
This effect explains why the original condition returns relatively quickly
when the treatment is discontinued.
The treatment current can be adjusted according to your individual sensitivity.
There is no risk involved as the current cannot exceed certain limits.
Treatment Fundamentals
The treatment concept of the HIDREX Tap-Water-Iontophoresis (TWI)
comprises two treatment phases:
Phase 1: The initial phase (therapy initiation) is sometimes conducted under
a doctor’s supervision. During this stage, patients learn to
administer treatments. For therapy initiation, at least three weekly
treatments of approximately 15 minutes each should be scheduled
(not more than one treatment per day). Sweat secretion will
normalize after approximately 10 treatments.
Phase 2: Long-term treatment (maintenance therapy) is necessary because
the TWI treatment effect is reversible. Depending on the severity of
the condition, maintenance therapy involves one to three weekly
sessions of approximately 15 minutes each.
Hint: It is up to the doctor to decide whether the initial therapy should be
partially or fully performed at the medical facility or at home with a loaner.
Hint: When using a special applicator, it is essential that you carry out a trial
phase. Instructions for this trial phase are enclosed with your applicator.
Efficacy Of Treatment And Polarity Reversal
In theory, the efficacy of Tap-Water-Iontophoresis (TWI) does not depend on
the direction of current flow. However, it has been clinically documented that
the area being treated with the anode (connector lA, see chapter Main
System Components) will produce slightly better results initially than the area
being treated with the cathode (connector lB).
HIDREX connect ION - Automatically Change of Polarity:
For a balanced therapy result on both treatment sides from the beginning of
the treatment, the polarity reversal function1(PWF) can be activated.
Therefore, the voltage will be gently reduced to 0V at the first half of your
treatment session, changes the polarity and rises back to your set voltage.
1The polarity change function can only be used if the therapy time is at least 10 minutes, as shorter
times would lead to ineffective treatment.

User Manual 2019-06-06, Rev.: 1.0
7
HIDREX classic ION - Manually Change of Polarity:
Despite this slight difference in efficacy in the current flow, it is recommended
to conduct all treatments in the initial phase (Phase 1) without changing
polarity until one side reaches an acceptable dryness level. Once normal or
acceptable dryness has occurred in one side of the treatment area (for
example, right hand), then it is advisable to reverse polarity and continue the
initial phase without changing polarity up to normal or acceptable dryness has
occurred in the other side of the treatment area (for example, left hand).
Once normal or acceptable dryness has occurred in both sides of the
treatment area (for example, both hands), then it is advisable to reverse
polarity for each treatment during the maintenance phase (Phase 2).
Polarity is reversed simply by changing which side of the treatment area is
treated by the anode or cathode.
For example, on the first treatment in the maintenance phase, if the right
hand was treated with the anode and the left hand was treated with the
cathode, then on the next treatment, the right hand would be treated with the
cathode, and the left hand would be treated with the anode. This sequence
would continue for every treatment.
Remark: Failure to do this does not cause any harm or side effects. Long-
term treatment results do not depend on the direction of current flow.
Types Of Current
The HIDREX devices have several options for the type of current used during
treatment of different areas:
ÖDC: Direct Current (Standard)
ÖPC: Pulsed Current
ÖVPC: Variable Pulsed Current
The classic direct current (GS) has the highest efficiency. However, the current
sensation of the GS is clearly distinct and sometimes unpleasant. Therefore,
the use of PS or VPS is highly recommended for the treatment of sensitive
skin areas (armpits, face, etc.) or children. Pulse current is significantly more
sensitive and the "feeling" of the current is significantly reduced.
The term pulse width:
The term "pulse width" used in this context defines a
parameter of the proportion of active current flow
during the therapy in percent (for example, a pulse
width of 60% means that the current flows in 60% of
the time)

8
2019-06-06, Rev.: 1.0 User Manual
Direct Current (DC):
In DC, the current (voltage) is being transmitted 100% of the time.
Öhighly efficient / distinct feeling of current (sometimes painful)
Pulsed Current (PC):
In PC, the current alternates its transmission between ON (the pulse) and
OFF (the pause) for equal lengths of time. The pulse and the pause are the
same duration1.
Ö sensitive (less feeling of current) / typically slightly less effective
Ö not recommended for treatment of feet or strong hyperhidrosis
Variable Pulsed Current (VPC):
VPC is a type of hybrid current between DC and traditional PC and allows for
the ON part of the cycle (the pulse) to run longer than the OFF part of the
cycle (the pause).
This device allows you to change the pulse-width in 10% increments (for
example, ON 60% and OFF 40% or ON 70% and OFF 30%, etc.). This allows
for more effective treatment AND a better comfort level. It is customizable for
your preferences and tolerance levels.
Övery sensitive (low current sense) / customizable effectiveness
Örecommended for all treatment areas
With increasing percentages of the
pulse-width, the length of the pulse is
increased, and the length of the
pause is decreased accordingly.
Due to the shorter pause, more
current is applied than in PC. The
chart to the right shows how
treatment efficiency increases as
pulse-width increases.
Extensive trials showed that the
efficiency of pulsed current could be
increased dramatically. The
effectiveness is not reduced at all compared to direct current when the pulse-
width is 90%.
1for example, 50 microseconds ON and then 50 microseconds OFF, and then the cycle repeats

Setup for Hands and Feet Treatment
Place one electrode1åinto each side of
the carrying case or ergonomic tray as
pictured at right.
When using the ergonomic trays é, make
sure that the pulled-down side of the tray
(palm rest) is on the side facing you.
Cover each electrode åwith one treatment
cloth æover the entire surface and insert
the two connection cables çaccording to
the colors on the connections of the
treatment electrodes å.
Make sure to forcefully push the connectors all the way onto the necks
of the treatment electrodes.
Fill both case sides äor ergonomic trays é
with warm tap water so that the skin
surfaces to be treated are well submerged.
The tops of the hand or feet should not be
covered with water, unless those areas
need to be treated.
Simultaneously Treatment of hands and feet:
For the simultaneous treatment of hands and feet, you need additional
accessories to work with the included components for hand-foot treatment.
The following items are required: 1) a set of ergonomic trays é2) the
accessory set DUO í(consisting of a pair of treatment electrodes å, plastic
nets æand DUO connection cables).
The carrying case can be used for foot treatment, and the ergonomic trays can
be used for the hands. One plastic net and one electrode should be placed
into each case side and tray, and then the sides and trays should be filled with
hand-warm tap water.
1Please remove the protective foils from the electrodes before using them!

14
2019-06-06, Rev.: 1.0 User Manual
The DUO cables ðare utilized to connect two electrodes each to one of the
grey cables as pictured below:
Now start the treatment in accordance with the instructions in the chapter
“Conduct Therapy”.
Please note that the simultaneous therapy of hands and feet does not always
achieve the optimal result. This is due to the probable different voltage
requirements and recommended pulse-width for each area. (Due to thicker
skin and less sensitivity, the feet are usually treated with higher doses than
the hands, and a higher pulse-width can usually be tolerated).
If the therapy does not have the expected effect on the feet, you should treat
the hands and feet separately.
Hints On Conducting Therapy
- Before starting treatment, thoroughly remove residues of fat-containing
care products from the skin.
- Wash the therapy area (e.g. hands) before each treatment with normal
soap and water to remove the skin's own fat and talc. Even small films of
fat can impair the flow of current and lead to local irritations.
- Do not use cream soap.
- Tap water iontophoresis leads to dry skin with frequent use and especially
at the beginning of therapy. Therefore, treat your skin immediately after
each treatment with a moisturizing care product.
- Use warm water, which is more absorbent and reduces the sensation of
electricity compared to cold water.

Primary Settings And Saving Of Profiles
Your HIDREX device offers you several treatment options that you must set
before starting treatment. The following paragraph explains how you can carry
out these basic settings and save them if necessary.
1) Turn the device on:
After setting up your HIDREX therapy system as described in the chapter
"Installation/Treatment Setup", switch on the control unit with the main switch
j.
First, the main display uwill briefly show
three moving bars for about 5 seconds (self-
test of the device).
Next, the currently set therapy duration is shown in
minutes on the left and the set dose in volts is
shown flashing on the right.
2) Select desired profile:
If a profile is selected (one of the LED •lights up), the device will automatically
suggest the respective stored treatment parameters (time, dose and pulse
width). In the delivery state, recommended default values are stored for each
profile. However, you can also create your own profiles.
If no profile is selected (none of the LEDs •are lit), the device always starts
in manual mode with the settings 15 minutes and 4 volts.
Select the profile as follows:

Begin Treatment
If you have no other treatment parameters known or given to you, the following
values are recommended as initial values for the therapy.
It is strongly recommended that you start treatment of children with reduced
parameters as indicated in the following table. If necessary, increase the
values slowly and pay attention to the patient's sensation! The treatment
should never be unpleasant or painful.
Attention: In order to avoid skin irritation by excessive dose settings in pulsed
mode (where current flow is practically imperceptible), we
recommend that you assess your individual direct current (pulse
width = 100%) thresholds for hands, feet, or armpits before you
start the first treatment session. To conduct axillary treatments, as
a rule the dose should not be raised above 15 volts, because the
sensitive skin may otherwise get burnt.
1) Starting:
Put your hands or feet in each water-filled tray and place them on the plastic
nets æ.
Attention: Avoid direct contact between skin and the metal
electrode! Do not forget to remove any jewelry!

2) Conduct treatment:
The device detects the closing of the circuit
("immersion monitoring") and signals the start
of the treatment. The dose in the display stops
flashing and slowly rises, starting at 4V, to the
previously set value1.
Attention: If you experience any localized pain during treatment, interrupt the
session and cover the painful area with petroleum jelly. Pressing
button •or Žwill stop the automatic increase of the dose.
3) Adjusting treatment parameters:
The treatment dosage may be increased or decreased at any time through-
out the treatment session by pressing buttons •or Ž.
The remaining therapy time cannot be changed once the treatment has
started.
4) Stop the treatment:
The treatment can be paused at any time by removing the hands or feet
easy. The treatment time is stopped (dose flashes again and shows the
selected value).
With stopped therapy, the treatment time and profile can no longer be
changed. The dose can then be changed with the •or Žkeys and the pulse
with by holding key Ž.
The treatment is continued by diving in the hands or feet in the water bath
again. As at the start of treatment, the dose value jumps to 4, stops
flashing and slowly rises again to the desired value.
5) Ending a treatment session:
The remaining treatment time is shown in minutes in the display, with the last
minute in seconds (flashing).
When the treatment time is up, the treatment dose is automatically lowered to
zero. Please keep your hands or feet in the trays until the dose display reads
"End".
Only switch off the device afterwards.
Attention: Do not turn off the device at main switch j, as long as the user is
connected to the device. Otherwise this can cause a safe but
uncomfortable electric shock, even if there are protection features
(electric fence effect).

Important Advice for Conducting Treatments
For your safety, your HIDREX therapy device is equipped with several
protective circuits.
Immersion monitoring
As long as you haven't closed the circuit through the skin surfaces to be
treated, the device won't deliver a therapy dose. All settings you make when
the therapy circuit is open are default settings. When the therapy circuit is
closed, the dose indicator stops flashing. Only then will the dose rise to the
previously set value and the therapy time expires.
Over-Treatment-Protection and therapy monitoring (OTP1)
The device permanently monitors the therapy circuit and the individual body
resistance of the patient. By this, problems in set-up and with the accessories
can be early recognized.
If a value that is too high is detected right at the start of therapy, the device
prevents the start of therapy.
If the device detects an increased value during
the current treatment, the display will alternate
showing the voltage and "ot". In this case you
can continue the therapy without danger.
If the value exceeds the limit for a longer period
of time, the device first reduces the dose briefly
and then slowly returns to the preset value.
If the resistance remains above the limit, the
device will stop the treatment, for your safety,
lock2the device and the display show "StoP".
Hint: If treatment does not start, "ot" or "StoP" is displayed, check the
connections and ensure that they are pushed completely. Also inspect
the electrodes for calcifications3and cleans as necessary. If you do not
notice any errors in the connections and the electrodes have been
adequately cleaned, the OTP feature is very likely to be active. In this
case, please pause the treatments for at least 2 to 3 weeks and at least
until the excessive sweating is clearly noticeable again. If this does not
help, please contact us.
1OTP = Over-Treatment-Protection
2To be able to start a new treatment a restart of the device is necessary.
