Intended use

The CyberHandler2 must only be used for ventilation and air conditioning of building. 
It includes:
•  filtering normally polluted air.
•  air cooling.
•  air heating.
•  air humidifying and/or dehumidifying

Proper use also includes observance of the operation manual and instructions from the manu-
facturer of the individual components, as well as the inspection and maintenance intervals stipu-
lated by Stulz.

Any use other than that described above is considered improper. If necessary, check if your 
units are suitable for your intended purpose and application. The manufacturer/supplier is not 
liable for any damages arising from improper use. The user alone bears the risk.

Misuse particularly includes:
•  Conveying any other gases except air
•  Conveying steam or water
•  Coarse filtering and/or filtering any other media except air
•  Chopping up or reducing size of materials
•  Drying out clothing
•  The unit is not suitable for handling abrasive media.

The CyberHandler2 unit is intended to be installed in environments with special conditions (for 
example: explosive areas, rooms with conductive dust, electromagnetic field or aggressive or 
corrosive atmosphere), consult previously STULZ Tecnivel to check the compatibility of the UTA 
with these conditions.

The CyberHandler2 unit should not be accessible to the public.

Safety Instructions

General 

These operating instructions contain basic information which is to be complied with for instal-
lation, operation and maintenance. They must therefore be read and complied with by the fitter 
and the responsible trained staff/operators before assembly and commissioning. They must be 
permanently available at the place where the system is used.

 INFORMATION

This unit contains fluorinated greenhouse gas covered by the Kyoto protocol

The AHU are to be properly assembled and used under precise observation of our instructions.

If the assembly is performed contrary to our regulations, and the defect/damage which has 
occurred is causally associated with inappropriate modification, processing or any other treat-
ment, all claims to damages compensation or warranty are thereby excluded.
