- Check safety equipment before putting into
service.
DECOMMISSIONING
- If the safety is affected when the equipment
is putted out of service, the refrigerant charge
shall be removed before decommissioning.
- Ensure sufficient ventilation at the equipment
location.
- Be aware that malfunction of the equipment
may be caused by refrigerant loss and a refrig-
erant leak is possible.
- Discharge capacitors in a way that won't cause
any spark.
- Remove the refrigerant. If the recovery is not
required by national regulations, drain the
refrigerant to the outside. Take care that the
drained refrigerant will not cause any danger. In
doubt, one person should guard the outlet. Take
special care that drained refrigerant will not float
back into the building.
- Evacuate the refrigerant circuit.
- Purge the refrigerant circuit with nitrogen for 5 min.
- Evacuate again.
- Fill with nitrogen up to atmospheric pressure.
- Put a label on the equipment that the refrigerant
is removed.

TRANSPORTATION, MARKING AND
STORAGE FOR UNITS THAT EMPLOY
FLAMMABLE REFRIGERANTS
TRANSPORT OF EQUIPMENT CONTAINING
FLAMMABLE REFRIGERANTS
- Attention is drawn to the fact that additional
transportation regulations may exist with re-
spect to equipment containing flammable gas.
The maximum number of pieces of equipment
or the configuration of the equipment, permitted
to be transported together will be determined by
the applicable transport regulations.
MARKING OF EQUIPMENT USING SIGNS
- Signs for similar appliances used in a work area
generally are addressed by local regulations
and give the minimum requirements for the
provision of safety and/or health signs for a
work location.
- All required signs are to be maintained and em-
ployers should ensure that employees receive
suitable and sufficient instruction and training
on the meaning of appropriate safety signs and
the actions that need to be taken in connection
with these signs.
- The effectiveness of signs should not be dimin-
ished by too many signs being placed together.
- Any pictograms used should be as simple as
possible and contain only essential details.
DISPOSAL OF EQUIPMENT USING
FLAMMABLE REFRIGERANTS
- See national regulations.
STORAGE OF EQUIPMENT/APPLIANCES
- The storage of equipment should be in accor-
dance with the manufacturer's instructions.
- Storage of packed (unsold) equipment
- Storage package protection should be con-
structed such that mechanical damage to the
equipment inside the package will not cause a
leak of the refrigerant charge.
- The maximum number of pieces of equipment
permitted to be stored together will be deter-
mined by local regulations.
