PRECAUTIONS TO BE TAKEN WHEN USING OF R-410A Refrigerant:
R-410A refrigerant is used in the unit; the following standard precautions for this gas should therefore be taken:
- The Vacuum Pump must have a Check Valve or Solenoid Valve fi tted.
- Pressure Gauges and Hoses for exclusive use with R-410A Refrigerant should be used.
- Charging should be carried out in the Liquid Phase.
- Always use scales to weigh-in charge
- Use the Leak Detector exclusive for R-410A Refrigerant.
- Do not use mineral oil, only synthetic oil to ream, expand or make connections.
- Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, fi lings, burrs, etc.).
- When there is a leak, collect what remains of the charge, create a vacuum in the unit and completely recharge with new R-
410A Refrigerant.
- Brazing should always be carried out in a nitrogen atmosphere.
- Reamers should always be well sharpened.
- Take very special care if 4-way or check valves are to be replaced since these have internal components that are very heat-sensitive such as
plastic, tefl on, etc.
- If a
compressor is to be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing
screws and replace the old compressor with the new one. Check that the new compressor has the correct oil charge, screw it to
the base and connect the lines and electrical connections.
- Evacuate above and below through the Schrader valves of the outdoor unit until -750 mm Hg is reached.
Once this level of vacuum has been reached, keep the pump running for at least one hour.
DO NOT USE THE COMPRESSOR AS A VACUUM PUMP.
- Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are no leaks.
4.- MAINTENANCE
4.2.- CORRECTIVE MAINTENANCE
All the components derived from the recycling of the unit should be managed according local legislation, and have
to be classifi ed and separated while dealt by authorized waste manager or be left in local waste facilities.
Refrigerant fl uids, electronic boards, heat exchangers and the oil extracted from the refrigerant circuit, as well as
the oil recipients used must be recycled as hazardous waste according the local normative through an authorized
waste manager or be left in local waste facilities.
The rest of the components considered as non-hazardous wastes must be recycled according to the corresponding
norms.
At the end of its life, the equipment should be recycled in local waste facilities or by an authorized waste manager.
