8.7 VENTILATED ROOM
Ensure that the area in question is outdoors or is sufficiently ventilated before entering the system
or carrying out hot work. Sufficient ventilation must be ensured during work. Ventilation must
distribute the released refrigerant safely and preferably guide it out into the outdoors.
8.8 TESTING THE UNIT
If electrical parts are to be replaced, they must comply with the intended use and the correct
specification. The manufacturer's maintenance and servicing guidelines must be followed at all
times. If in doubt, contact the manufacturer's technical department.
The following tests must be carried out for systems with flammable refrigerants:
 The filling amount corresponds to the room size that the parts containing the refrigerant are
installed in;
 The machines and ventilation openings are working properly and are not blocked;
 If an indirect refrigerant circuit is used, check that refrigerant is present in the secondary circuit;
 The markings on the units remain visible and legible. Illegible markings and signs must be
replaced;
 The refrigerant pipes or components are installed so that they are highly unlikely to be exposed
to any substance that could corrode components containing refrigerant, unless they are made
of corrosion-resistant materials or are adequately protected against corrosion.
8.9 ELECTRONIC VERIFICATION
The repair and maintenance of electrical parts requires initial safety tests and procedures for
checking the parts. If there is a defect that could jeopardise safety, no power supply may be
connected to the circuit until the defect has been sufficiently remedied. A temporary solution must
be found if the error cannot be rectified immediately and it is still necessary to continue operation.
The system's owner must be informed of this so that all parties involved are instructed accordingly.
The initial safety checks include:
Discharging the condensers: This must be done safely to avoid the risk of sparking;

Ensuring that no electrical components or lines are live when charging, restoring or flushing

the system;
Ensuring that a continuous earth connection exists.

WARNING!
The system must be installed in rooms that meet the specified room size; see the technical data
regarding this matter.
The system may not be installed in a place where flammable gas could escape.
NOTE!
The manufacturer may provide other suitable examples or additional information about what the
refrigerant smells like.
9.0 DISPOSAL
At the end of your item's long service life, please dispose of the valuable raw materials properly
so that suitable recycling can take place. If you are not sure how best to proceed, local waste
disposal companies or recycling centres will be happy to help.
WARNING!
Releasing refrigerant into the atmosphere is strictly prohibited!
