Installing/Replacing The Co; Gas Cylinder And Switching On The Unit - BWT AQA drink Pro 20 CAS Einbau- Und Bedienungsanleitung

» Install a shut-off valve before the device.
» Install the pressure reducer, the water stop and the water filter correctly and connect the
to the water dispenser (WATER INLET).
» Set the pressure reducer to 3 bar to limit the incoming water pressure at the device.
» Open the shut-off valve.
» Now connect the device to the mains or switch on the device.
» Press the selection button for still, cold water (COLD) until water comes out of the water
outlet.
» Press the selection key for ambient water (STILL) until water comes out of the water outlet.
» Briefly press the selection key for sparkling water.
» Check the device for possible leaks.

5.5 INSTALLING/REPLACING THE CO

UNIT
Observe the manufacturer's warnings and transportation and storage regulations.
Protect gas cylinders from excessive heat, mechanical damage and corrosive substances.
Do not connect or store gas cylinders in zones with an increased fire hazard.
Place gas cylinders at a distance of at least 0.5 m from radiators.
Place gas cylinders so that they are easily accessible.
Place gas cylinders away from emergency exits and escape routes.
Store full and empty gas cylinders separately and according to the type of gas.
Gas cylinders may only be stored and transported when the covering cap is screwed on.
Gas cylinders must be stored upright and secured against falling over.
Only connect gas cylinders with pressure reducers and safety valves.
In the event of leaks or fire: close the cylinder valves immediately. Cool heated cylinders with
water.
In workshops and laboratories, set up only as many reserve cylinders as you need for continu-
ous operation.
Do not oil or grease cylinder valves.
Close the cylinder valves when the unit is to be decommissioned or when the gas cylinders
are empty.
Once the device is connected to the water supply, the CO
only food grade CO (E290).

If the calculated gas concentration of 3% is exceeded, the following measures are possible:
» Use of a smaller CO gas cylinder

» Increase in the size of the room (e. g. by removing doors)
» Installation of a CO gas warning device in accordance with DIN 6653–2

» Installation of technical ventilation
A functional check of the gas pressure reducer should be carried out before installing the CO
cylinder.
The CO pressure should be set at 3.5 bar. Depending on personal taste this can be set up to
2
4 bar. The higher the pressure the more sparkling the water.
