  • Page 4: Safety Considerations

    1. Safety Considerations IMPORTANT! Please Read Before Starting This air conditioning system meets strict safety and operating standards. As the installer or service person, it is animportant part of your job to install or service the system, so it operates safely and efficiently.
  • Page 5 firehazard. When Transporting Be careful when picking up and moving the indoor andoutdoor units. Get a partner to help, and bend yourknees when lifting to reduce strain on your back. Sharpedges or thin aluminum fins on the air conditioner cancut your fingers. When Installing ●In a Ceiling or Wall Make sure the ceiling/wall is strong enough to hold theunit’s weight.
  • Page 6 regulations 2. Marking of equipment using signs Compliance with local regulations 3. Disposal of equipment using flammable refrigerants Compliance with national regulations 4. Storage of equipment/appliances The storage of equipment should be in accordance with the manufacturer's instructions. 5. 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.
  • Page 7 Where electrical components are being changed, they shall be fit for the purpose and to the correct specification. At all times the manufacturer's maintenance and service guidelines shall be followed. If in doubt consult the manufacturer's technical department for assistance. The following checks shall be applied to installations using flammable refrigerants: –...
  • Page 8 8. Repair to intrinsically safe components Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed the permissible voltage and current permitted for the equipment in use. Intrinsically safe components are the only types that can be worked on while live in the presence of a flammable atmosphere.
  • Page 9 This process may need to be repeated several times. Compressed air or oxygen shall not be used for this task. Flushing shall be achieved by breaking the vacuum in the system with OFN and continuing to fill until the working pressure is achieved, then venting to atmosphere, and finally pulling down to a vacuum.
  • Page 10 equipment are closed off. k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and checked. 15.Labelling Equipment shall be labelled stating that it has been de-commissioned and emptied of refrigerant. The label shall be dated and signed. Ensure that there are labels on the equipment stating the equipment contains flammable refrigerant.
  • Page 11 The appliance shall be stored in a well-ventilated area where the room size corresponds to the room area as specified for operation. The appliance shall be stored in a room without continuously operating open flames (for example an operating gas appliance) and ignition sources (for example an operating electric heater). Any person who is involved with working on or breaking into a refrigerant circuit should hold a current valid certificate from an industry-accredited assessment authority, which authorized their competence to handle refrigerants safely in accordance with an industry recognized assessment...
