• Weld and braze air conditioning systems without refrigerants only in suitably ventilated rooms.
• If the system emits a pungent smell this means that the refrigerant has decomposed due to
overheating. Immediately leave the room and return only after it has been suitably ventilated or
when wearing a gas mask for acid gases.
• It is absolutely essential to comply with the first aid measures if accidents occur.
1.5. Safety and environmental requirements
The following requirements relate to the operation of refrigerating plants within the European
Community.
• The used components must correspond to the pressure equipment guide-line EC/97/23 and EN
378 part 1-4.
• Independent of the design, the equipment and inspection before the delivery, also the operator of
such plants has duties according to EN 378 and national regulations.
This concerns the installation, the operation and the repeated inspection:
Installation: according to EN 378
Operation:
Determination of emergency measures (accidents, malfunctions)
Creation of an abbreviated instruction and notification (template page)
a. A unit protocol must be kept
b. To be stored in the proximity of the unit
c. Access for competent staff in case of repairs and repeated inspection must
be ensured.
Repeated inspection: according to EN 378. The operator is responsible for the execution.
The operator must ensure that all maintenance, inspection and assembly work is carried out
by authorised and qualified specialist staff who have made an in-depth study of the operating
instructions.
It is absolutely essential to comply with the procedure for shutting down the system described in the
operating instructions. Before maintenance work, the unit must be switched off at the main switch
and a warning sign displayed to prevent unintentional switching-on.
Efficiency of safety devices must be kept during the whole life cycle of the unit. In order to perform
this task, please follow the prescription given in Chapter 8.
First aid measures
• If health problems occur during or after handling fluorinated hydrocarbons, a doctor is to be
consulted immediately. The doctor is to be informed that the work involved the use of fluorinated
hydrocarbons.
• In the case of acute effects, the casualty is to be brought into the fresh air as quickly as possible.
• The casualty must never be left unsupervised.
• If the casualty is not breathing, initiate mouth-to-mouth resuscitation immediately.
• If the casualty is unconscious or very dazed he or she must not be given any liquid.
• Splashes of fluorinated hydrocarbons in the eyes can be removed by an assistant by blowing air or
using a fan. Then rinse with water.
• Independent conversion and manufacture of replacement parts.
• The system may only be converted or modified after consultation with STULZ. Original
replacement parts and replacement parts/accessories authorized by STULZ are an aid to safety.
