 8 

The following rules should always be observed: 

1.

 

Keep the work area clean

. Clutter can create hazards around the device. Keep the work area 

well illuminated. 

2.

 

Do not use the machine in explosive atmospheres or environments

. Do not use the machine 

near flammable substances. 

3.

 

Handle 

the power supply cable with care. 

Do not pull 

the electric cable to disconnect it from 

the plug without removing power from it first. Keep the electric cable away from heat, oil, 
water and sharp edges. 

4.

 

Protect yourself 

from electric shock. Avoid any contact with earthing surfaces. 

5.

 

Never expose

 the device to rain or very damp conditions. 

6.

 

Keep children and people without explicit knowledge

 of the device and its function away to 

a safe distance. 

7.

 

Only use

 demineralised water according to the specification stated in this manual. 

8.

 

Never operate 

the device in confined spaces without additional safety infrastructures, such 

as active ventilation or hydrogen detection systems. 

9.

 

Always wear personal protection devices:

 

a.

 

Wear protective goggles and nitrile gloves 

when handling the electrolyte solution. 

b.

 

Wear ear muffs or plugs

 in noisy areas. 

c.

 

Wear gloves when handling the device.

 Always wear appropriate PPE when handling 

the modules. 

d.

 

Wear appropriate footwear

 when handling the device. 

e.

 

Use lifting aids

 if available when lifting the device. Never lift the device alone. Know 

your local and site-specific health and safety rules and act accordingly. 

10.

 

Always disconnect 

the machine from electricity before any maintenance and transport. 

11.

 

Only  use 

the  machine  in  the  way  and  for  the  purposes  mentioned  in  this  manual.  If  the 

machine is utilised for uses other than what is specified in this manual, unforeseen hazards 
may present themselves. 

12.

 

Ensure  that  the 

back  pressure

  on  the  Electrolyser  (e.g.  by  a  storage  tank) 

never  exceeds 

35 barg

13.

 

Use the handles

 when lifting and moving the device. 

14.

 

Never  attempt  to  repair  the  machine 

by  yourself.  The  machine  must  be  repaired  only  by 

qualified service specialists who use original spare parts; otherwise, risks may arise for the 
operator. 

15.

 

Any  maintenance  activity,  excluding  the  ones  listed  in  the  routine  maintenance  and 
installation sections, are only allowed to be performed by authorized 

trained technicians

16.

 

Any person working on the system must be familiar with the hazards and risks associated with 
installing, commissioning and running the device and attached machines 

17.

 

Do not store

 the unit at temperatures below 1°C. If this occurs, a freezing check sticker placed 

on the EL 2.1 Electrolyte bag box will become RED. In this case, please contact Enapter support 
team before commissioning the device.
