Precautions for Installation
1. Install the HOCl storage tank in a well ventilated place. Avoid direct sunlight. (If you want to install the device outdoors, please contact your local seller.)
2. Do not install in humid place. (Avoid places where condensation may occur, especially during winter.)
3. Water supply condition: Temperature: 10~40℃(50℉~104℉), Flow Rate : 1.3~2.0 L/min, Water Pressure : 3 - 5 bar
4. Check the pH of the water before installation.
5. Do not block the HOCl outlet.
6. When installing on a table, install it horizontally on a stable table.
7. For the optional specifications, contact your local seller.
8. If re-location is needed after installation, contact your local seller.
1. Do not install in an enclosed place without ventilation. (Install in a well-ventilated area.)
2. Do not install in areas of explosion hazard or flammable material.

Cautions for Use
Caution
This device is for single-phase
AC 100~240V, 50~60Hz only.
Hold the power plug when unplugging.
Please contact your local seller
for repair of the power plug.
If the main unit is submerged, it may
cause an electric shock. Unplug the
power plug from the electric outlet, pull
up the main unit and ask your local seller
to repair it.
If the electric outlet is wet, unplug the
power plug and dry it completely before
use.
Do not use damaged power plug or
loose socket outlets.
This may cause a fire or electric shock.
Do not pull the power cord.
This may cause a fire or electric shock.
Do not touch the power plug with
wet hands.
Do not twist or press the power cord
and make sure it is not broken.
Be sure to unplug the power plug when
moving, repairing, or inspecting the device.

HOCl Cautions
1. HOCl must be kept in a storage tank made of PE, PVC or FRP.
2. When HOCl is exposed to organic materials, it may reduce the sterilizing ability.
3. Note that the sterilizing ability of HOCl will decrease rapidly when HOCl is exposed to light.
4. When using stored HOCl, check the pH and chlorine concentration before use.
1. Do not add anything to HOCl. If any chemicals added, this may generate chlorine gas.
2. Do not use HOCl at 50℃(122℉) or higher.
3. Do not use HOCl in enclosed places.
4. Do not place HOCl storage tank nearby the inflammables.
※For more information, please refer to the Safety Data Sheet (SDS) provided by your local seller.

Precautions for handling 3% HCl Solution
1. Use only the 3% HCl solution supplied with the device.
2. When handling, wear protective goggles, gloves and clothes if necessary. Also wash your hands thoroughly after handling.
3. If the 3% HCl is spilled on metal, rinse with sufficient amount of water.
4. Do not subdivide or transport into other containers.
5. Do not reuse the container. Used container should be washed with water before disposal.
6. Make sure to ventilate when using. Chlorine gas may be generated.
7. When spilled on the floor or appliances, wash it with plenty of water.
8. Keep away from direct sunlight.
9. Handle carefully during transportation as it may leak.
1. 3% HCl solution is highly corrosive.
2. Skin contact may cause burns or inflammation.
3. Inhalation or ingestion may cause irritation.
4. Do not mix with other chemicals.
5. Eye contact may cause blindness.
6. Use it only for intended use.
※For more information, please refer to the Safety Data Sheet (SDS) provided by your local seller.

Contact on clothing or shoes ▶Remove contaminated clothing or shoes and wash skin with plenty of water.
Do not try to neutralize the acid with alkaline solution.
Eye contact ▶Do not rub your eyes and wash immediately with running water for at least 15 minutes.
Ingestion ▶Drink plenty of water and immediately contact a doctor.
Inhalation ▶Move to a place where there is fresh air.

Mechanism of
HOCl Generation
ecoTree SLB-120
ecoTree SLB-120 uses un-divided electrolytic cell system.
It generates Hypochlorous acid (HOCl) through electrolysis of 3%
HCl and dilution with water.
Electrolysis
In general, electrolysis refers to the oxidation-reduction reaction of
an electrolyte using electric current. HOCl, widely known as an eco-
friendly disinfectant, is generated by this mechanism.
