Neater makes different versions of electrolyze based on your needs.
Electrolysis come in AC/DC or DC/DC versions as well as air-cooled or liquid-
cooled versions (LC).
Follow Installation Instructions in the Owner’s Manual
Device out-of-the-box comes in Maintenance mode.
Yellow LED should be steady. Do not leave it turned on and unattended for a
long time.
You must follow owner’s manual for all steps, including pipe and wire connection, operation, transportation, storage and disposal.
Insert the two supplied jumpers into the Dry Con. port in the 3rd and 4th
positions on the front panel of the EL. If you want/need to implement a safety
chain, please refer to Dry Contact Connection Guide in the owner’s manual.
Screw supplied antenna to the Ant. port.
Plug the power cable into the Power port
AC – protective earth on the left, live on the right.
DC – positive on the top. and switch the power on.
Water Inlet Requirements
H2O IN port is used for automatic refilling from connected demineralized water
source during normal operation, first refilling and maintenance. During
hydrogen production water consumption rate is around 400 mL/hr.
Proper inlet water source must be connected before proceeding to the next
steps.
Flush all water pipes with demineralized water before connecting your device
to ensure nothing is stuck in the lines.
Сonnect electrolyze to water supply only through water purification system according to the Owner’s Manual. Water conductivity must be < 20 µS/cm (at 25°C) and pressure between of 1-4 bar.
Optional
External Neater Water Tank
Use Enapter Water Tank to solve the problem of unstable water supply. It can
be filled manually with prepared demineralized water as well as directly
connected to water source.
Enapter Water tank deliveries pressure up to 2.75 bar.
Water conductivity must be < 20 µS/cm (at 25°C).
EL4.0 LC version
Cooling Loop Requirement
Cooling Water ports (normally closed) are used for cooling the system using
water or a water glycol mixture. Check the manual to guarantee the optimal
temperature as a function of your flow rate and ambient temperature.
The required flow rate is 1-2 L/min and input pressure can’t exceed 4 bar.
Make sure you are not reversing the IN and the OUT.
Check H2 Vent and O2 Vent Lines
It is the installer’s responsibility to regularly check and maintain H2 VENT and O2 VENT lines, as well as keeping the lines free of ice and any obstructions.
DO NOT connect H2 VENT line with O2 VENT line.
Mixing these outputs is extremely dangerous.
Always check H2 vent and O2 vent lines for blockage and damage.
Make sure there is no obstruction into the H2 VENT line. This can cause
irreparable damage to your hydrogen system
No blockage should be present on O2 VENT on the user side of the interface.
Connect the Electrolyze to Enapter Cloud
https://play.google.com/store/apps/details?id=com.enapter&hl=ru
To download the Enapter mobile app, scan the QR-code or visit app.enapter.com from your Android or Apple mobile phone.
6 Skip this step for isolated setups with no internet connection.
Power on the device.
Make sure antenna is turned on (blue led steady on the front panel of
electrolyze).
Open the Enapter App and follow the steps to create your site in the Enapter
Cloud.
Press the Add device button.
Scan QR-code located on the front side of the device and follow the Enapter
app instructions.
If you can’t scan the QR code, enter the device ID and PIN manually. You can
find them on the back of the device.
Device connected.
Monitor device activity in Enapter App or Enapter Cloud.
Access the Electrolier’s Web GUI
For Isolated setups with no internet connection use Enapter Web GUI (Graphical
User Interface) to monitor and control the device locally through a web
browser.
Instructions on how to access Electrolier’s Web Interface are available at
handbook.enapter.com.
Option A For sites with a local WiFi network. This connection type allows
users to access web interface of multiple electroliers’ and also use it via
mobile web browser.
Option B Connection via ETH (Ethernet) port on the front panel of the
device allows users to access the web interface of a single electrolyze.
Alternating current voltage of 220-240V is potentially lethal!
Direct current voltage of 48-60V can be a hazard!
The First Electrolyte Refilling
Follow Enapter App or Web GUI instructions to refill the electrolyze for the first time.
Water inlet must be connected during electrolyte refiling and draining routines for Electrolyze 4.0.
Make sure electrolyser is in maintenance mode and drained.
Prepare electrolyte bag with 2L of the 1,54% KOH solution and supplied
refilling pipe. Do not dilute the electrolyte!
Connect the refilling pipe to the bag using the special connector.
Insert the opposite end of the pipe to the Fill/Drain Port.
To start refilling carefully raise the electrolyte bag above the device.
Refilling will start automatically. Pour out all of the solution from the
electrolyte bag. Disconnect refilling pipe from the Fill/Drain port. If you
forget to disconnect the pipe, electrolyser can be overfilled during the next
steps or KOH concentration might be wrong. If that happens, the device will
require service checkup.
Press Exit Maintenance Mode button.
Electrolyser will be filled with required amount of water automatically.
Electrolyser Is Ready for Hydrogen Production.
Electrolyser is Ready for Use!
During normal operation the LEDs indicate the status of the machine. Monitor
device activity in Enapter App, Enapter Cloud or WEB GUI. 
Optional Connect any energy devices to Enapter Cloud
To integrate solar inverters, power meters, fuel cells, irradiance sensors,
etc to Enapter Cloud you will need a suitable Universal Communication Module
(UCM) and a Blueprint.
Visit marketplace.enapter.com to find out
which device integration
Blueprints are already available. To learn how to develop your own Blueprints
visit developers.enapter.com.
