2 Safety notes
2.1 General safety notes
Warning
Risk of injury from sharp-edged plates and chemicals
Wear protective gloves for all maintenance and repair work.
Wear protective clothing, protective gloves and protective goggles when dealing with chemicals.
Never insert or pull out the plug with wet hands.
Never remove the plug from the socket using the cord.
Do not look directly into the water outlet and the UVC lamp behind it.
2.2 Carbonic acid bottle
Danger
Danger of suffocation by carbon dioxide
Carbon dioxide (CO2) is a colourless and odourless gas and, at high concentrations in
the air, leads to suffocation.
Outflowing carbon dioxide is heavier than air. A risk of suffocation occurs in the case of a
high accumulation in closed rooms.
Only use the supplied gas hose for the gas connection. For other hoses with the same outside diameter,
the wall thickness may be too low.
The carbonic acid bottles may only be used in combination with a suitable gas pressure reducer (max.
5 bar operating pressure).
Please follow all the instructions in the water dispenser operating instructions for the operation and stor-
age of the carbonic acid bottle.

2.3 Maintenance and repair work
The plug must be pulled from the power supply for all installation and maintenance work.
Maintenance and repair work may only be performed by service technicians authorised by EauVation.
Inappropriate maintenance or repair work can result in serious risks for the user, for which EauVation
shall not accept liability.
Original spare parts must be used for repairs or to replace consumable parts. If original spare parts are
not used, the warranty is invalidated.
Caution
Possible leakage from improperly cut hoses
Use the hose cutter to ensure the hose cross section remains round and that the hose is
cut straight.
Caution
Possible leakage from damaged hoses
Check the hose. If there are any scores on the hose, shorten the hose or replace it to
ensure a tight plug connection.

4.1 Requirements
Raw water requirements
The quality of the water at the inlet must fulfil the valid drinking water regulations applicable to the specific
country. In addition, the following threshold limits must be adhered to (16).
Installation site requirements
Frost free
Well ventilated, clean, dry
Firm, level surface for the water dispenser
No sources of heat next to the water dispenser
See Chapter 16 for space requirements and minimum clearance from the wall.
The water shut-off valve and the water dispenser must not be more than 3 m distance from one another.
Stagnant water in long hoses can lead to contamination.
Minimum room size to prevent a hazardous concentration of carbon dioxide (please see table).

IMPORTANT A gas alarm device must be installed if the room is less than the minimum room size.
Alternative: 2-fold air exchange within 24 hours (continuous exchange of air).
If the water dispenser and the carbonic acid bottle are located in different rooms, the
minimum room size shall apply to both rooms.
4.2 Water connection
Warning
Possible contamination
The water stop cock and the water dispenser must not be more than 3 m distance
from one another. Stagnant water in long hoses can lead to contamination.
Only use the supplied water hose for the water connection.
Caution
Possible leakage from improperly cut hoses
Use the hose cutter to ensure the hose cross section remains round and that the hose is
cut straight.

IMPORTANT: Do not insert the hygiene filter yet.
Wash hands, put on protective gloves and spray with EAUVATION N° 2.
Connect hoses to all the components. Before inserting the hoses, spray the end of the hoses with
EAUVATION N° 2. Do the same for the hose connections of the components.
The pressure gauge is removed again later. Therefore, the hose between the pressure gauge and the
water clock must be sufficiently long.
Insert the water connection hose into the
“FILL THE ICE-BANK” connection.
All connectors must be secured with locking clips.
Setting the water clock
Set 8000 l water volume (12).
4.3 Waste water
The drip tray can be connected to the waste water.
Waste water connection requirements:
Trap
Level lower than the drip tray
Hose to the waste water connection has a steady gradient to ensure no backlog of water

Setup and connection

4.4 Gas connection
Caution
Possible discharge of carbonic acid
The gas connection must always be performed by an instructed service technician.
National guidelines must be observed.
Secure the carbonic acid bottles to prevent them from falling over by using the sup-
plied securing strap. If a bottle is not standing up, the liquid carbonic acid ices up the
gas pressure reducer and puts it out of operation.
Only use the supplied gas hose for the gas connection. For other hoses with the same
outside diameter, the wall thickness may be too low.
Caution
Possible leakage from improperly cut hoses
Use the hose cutter to ensure the hose cross section remains round and that the hose is
cut straight.

Before installation
Check whether the following conditions are met:
Carbonic acid bottle available and sealed tightly.
Carbonic acid is of food quality grade (E290 marking).
Size of the room matches the size of the carbonic acid bottle (4.1).
Gas pressure reducer is approved up to 5 bar: see red marking on the operating pressure gauge.
Seal is present and undamaged in the union nut of the gas pressure reducer.

Open the valve of the carbonic acid bottle and check whether carbonic acid leaks as gas (not in liquid
form).
Close the valve of the carbonic acid bottle.
Screw the gas pressure reducer tightly to the valve of the carbonic acid bottle using a suitable open-end
spanner.
Connect a shut-off valve to the gas pressure reducer with a short hose (approx. 100 mm).
Close the shut-off valve.
Connect the water dispenser and the water shut-off valve with a hose.
All connectors must be secured with locking clips.
Do not yet open the valve of the carbonic acid bottle.
Point out to the operator that he/she is responsible for the following:
The room in which the water dispenser and the carbonic acid bottle are placed must be sufficiently
large (4.1). If the room is too small: ensure adequate ventilation or have a gas detector installed.
Access to this room must be marked with the warning signs W18 with additional text and W029.
Create a safety risk assessment.
Place a sign where the carbonic acid bottle is placed about the maximum size of the bottle.
Keep a logbook.
