Disposal Of Equipment Using Flammable Refrigerants - Black & Decker BXAC9001E Original Instructions Manual

ENGLISH (Original instructions)
♦ Purge the refrigerant circuit with nitrogen for 5 min.
♦ Evacuate again.
♦ Remove parts to be replaced by cutting, not by flame.
♦ Purge the braze point with nitrogen during the brazing
procedure.
♦ Carry out a leak test before charging with refrigerant.
♦ Reassemble sealed enclosures accurately. If seals are
worn, replace them.
♦ 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 refrigerant 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
16
Transport of equipment containing flamma-
ble refrigerants
♦ Attention is drawn to the fact that additional transpor-
tation regulations may exist with respect 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 gen-
erally 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 employers
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 diminished 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 accordance with
the manufacturer's instructions.
♦ Storage of packed (unsold) equipment
♦ Storage package protection should be constructed 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 determined by local
regulations.
