WORKING PRINCIPLE

CO exits the bottle, gets through pressure regulator and CO line, goes on keg head firmly adjusted to beer barrel.
2
With pressure of CO which is higher than pressure in the barrel, beer is pressed through the valve on keg head
2
and with beer line it is brought to the cooling unit. Beer is cooled by passing through beer coils which are
connected to taps (for undercounter unit they are mounted on tower) for beer dispensing in the glasses (mugs).
To prevent risk of injuries and damages, bottle CO2 always has to be positioned in vertical position,
!
fixed on wall holder. If there is any doubt on gas release, especially in small spaces, it is necessary to
Danger
ventilate potentially contaminated space.

INSTALLATION

In accordance to current law regulations, installation and release of cooler in function, this needs to be
!
done by specialized and trained technical staff.
Warning
There are 2 basic groups of coolers for cooling and dispensing beer:
- Coolers for cooling beer with water bath
- Coolers for cooling beer with aluminum block
Each cooler consists of cooling device and cooling bath or aluminum block.
Cooler can be installed in outdoor ambient under condition that it is protected from rainfall and direct sun rays. If it is
installed in inner ambient, it needs to be in the space where room temperature does not over cross borders of climate
class which can decrease cooling efficiency.
Cooler needs to be properly set on surface where maximally allowed incline is 2 degrees. For installation of cooler with
air cooling it is necessary to assure enough free space for cooler (0,4m in front of air entrance/exit). Cooler needs to be
set on straight surface with enough fresh air, away from heat source, minimally 7cm from the wall and 30cm from the
other cooler. Free air circulation around cooler needs to be assured.
!
Please assure enough air circulation for fan !
Warning
Each cooler produced with refrigerant R290 in amount of 150g (look at Technical data), needs to be
installed in ambient with minimum volume of 19m3 (max allowed is 8g/m3). Coolers cannot be
installed in ambient used as halls or emergency exits. Coolers from group 3 (in the cooling system is less
Danger than 150g) can be installed anywhere without extra precautions according to the norm EN-60335-2-
89.
