Contact with parts that could become live when the unit is 
started up can result in electric shock, burns or death by 
electrocution.  
When there is no need for circuits to be powered up, set the 
isolating switch on the power line to the OFF position, 
padlock it and post a warning sign. 

MOVING PARTS 

Contact with the fan rotors can cause injury.  
Before removing the protective grilles or the fans 
themselves, make certain the isolating switch on the power 
line to the unit is set to the OFF position and padlocked, 
and post a warning sign.  
Before removing the protective grilles or the fans 
themselves, make certain the isolating switch on the power 
line to the unit is set to the OFF position and padlocked, 
and post a warning sign. 

REFRIGERANT 

In the event of safety valves coming into operation and 
releasing refrigerant gas, persons in the vicinity can be 

injured or suffer toxic effects. Always wear suitable clothing 
and protective goggles when working in potential hazard 
areas.  
In the event of refrigerant gas escaping, refer to the “Safety 
datasheet” for the particular refrigerant. 
If an open flame or heat source is brought into contact with 
the refrigerant, or the pressurized gas circuit should 
overheat (e.g. during welding operations), this can cause 
explosion or fire. Do not position any heat source within the 
hazard area.  
Maintenance or repair operations involving welding must be 
carried out with the system emptied of refrigerant. 

WATER SYSTEM 

Defects affecting pipelines, connections or valves and other 
control componentry can result in water being leaked or 
sprayed from the system, occasioning damage to property 
or causing short circuits in the unit.  
Make certain all hydraulic connections are securely made, 
following the directions given in the present manual.

Special protection means. In close spaces, use the self-breather.  

06 Measures 

against 

the accidental 
leakages of the 
product.  
 

Personal protections. Evacuate the personnel in safety areas. Foresee adequate ventilation. Use means of 
personal protection.
