Safety Instructions 

1.1.

 

Setup / Commissioning 

The use and maintenance of the machine shall be limited to trained personnel only. 

Place the unit upright standing in a horizontal, level, dry, and clean place. Ensure that the power connection 
cable is routed directly to the socket. Do not locate multiple portable socket-outlets or portable power 
supplies at the rear of the appliance. The connecting cable must never be kinked or squeezed and the 
lateral openings require a free distance of 5 cm to provide the required air circulation. The free distance 
behind and above the dispenser must be as well 5 cm. The dispenser front, with the tap outlet must stay 
open and uncovered. 

As an operator pay attention to the listed safety measures: 

 

Operate dispenser within a temperature range of +6 to +35°C  

 

Prevent dirt (dust, fibers, etc.) from entering the unit 

 

Connect only the specified supply voltage. 

 

The wall socket used must be connected to an overcurrent protection device (16A). 

 

The device may only be operated with a properly wired protective earth conductor. 

 

Protect the device against moisture 

 

Do not insert objects into rotating parts (fan or compressor) 

 

Observe the warning, safety and service instructions in this manual 

1.2.

 

Operations 

The device described here may only be operated by suitably trained persons. Children shall not play with 
the machine. This machine can be used by children aged from 8 years and above and persons with reduced 
physical, sensory or mental capabilities or lack of experience and knowledge if they have been given 
supervision and instruction concerning use of the machine in a safe way and if they understand the hazards 
involved. Cleaning and user maintenance shall not be made by children. 
Do not use a water jet for cleaning purposes. 

Keep ventilation openings, in the appliance enclosure, clear of obstruction. The air circulation must be 
possible at any time. 

Do not damage the refrigerant circuit. The R290 refrigerant is an extremely flammable gas.  

Serious personal injury and material damage can be caused by: 

 

Improper use 

 

Incorrect installation or operation 

 

Unauthorized removal of the necessary protective covers or housings 

 

Invalid opening of the device during operation 

 

Failure to comply with the applicable legislation / standards for beverage dispense installations. 

 

Service and repair jobs where access to the machine inside is required, may only be carried out by a 
trained or instructed technician 

If, for any reason, it can be assumed that the safety is impaired or when it is changed from normal 
operation, the appliance must be put out of service and marked so that it is not inadvertently put back into 
service by a third party. In addition, the customer service has to be notified. Safety may be impaired if the 
appliance is not working properly or is visibly damaged.
