Make sure the area is outdoors or adequately ventilated before breaking into thesystem m or
doing hot work. During the duration of the work, a certain degree of ventilation must remain.
The ventilation should safely distribute released refrigerant and preferably release it into the
atmosphere from the outside.
When electricalcomponents are replaced, they must be suitable for the purpose and the
correct specification. The manufacturer's maintenance and service guidelines must be
followed at all times. If in doubt, contact the manufacturer's technical department. For
installations with flammable refrigerants, the following tests shall be carried out: The filling
quantity corresponds to the size of the room in which the refrigerant-containing parts are
installed. The ventilation units and outlets function properlyand are not disabled. If an indirect
refrigeration circuit is used, the secondary circuit must be checked for the presence of
refrigerant. The marking of the device is still visible and legible. Markings and signsfor
are illegible, shall be corrected; Refrigeration lines or components are installed in a place
where they are unlikely to be exposed to substances that can attack refrigerants containing
components
unless thecomponents are made of materials that are inherently corrosion-resistant or suitwise
protected against corrosion.
Repairs and maintenance of electrical components shall include initial safety checks and
component inspection procedures. If there is a fault that could jeopardise safety, no
electrical supply shall be connected to the circuit until it is satisfactorily resolved. If the fault
cannot be rectified immediately,operations must continue and an appropriate temporary
solution shallbe used. This must be communicated to the owner of the device so that all
parties are informed.
The first safety tests include the following: Discharge ofcondensers: This must be done in a safe
manner to avoid sparking. No live electrical components and cables must be exposed while
the system is being charged, restored or flushed. that there is a continuity ofcommitment.
In the case of repairs to sealed components, all electrical supply lines must be disconnected
from the equipment to be processed before removing sealed covers, etc. If an electrical
supply of the equipment is absolutely necessary during maintenance, a permanently
functional form of leak detection must be present at the most critical point to warn of a
potentially dangerous situation.
Particular care must be taken to ensurethat when working on electrical components, the
housing is not altered in such a way that the level of protection is impaired. This includes
damage to cables, too many connections, terminals that do not correspond to the original
specification,damage toseals, incorrect assembly of fittings, etc. Make sure that the device is
securely mounted. Make sure that seals or sealing materials are not damaged and no longer
serve the purposeof preventing the entry ofcombustible atmospheres. Spare parts must
comply with the manufacturer's specifications.
NOTE: The use of silicone sealants may affect the effectiveness of some types of leak
detectors. Intrinsically safe components donot need tobe insulated before work.
Do not apply permanent inductive loads or capacitance loads to the circuit without ensuring
that they do not exceed the allowable voltage and current for the device beingused.
