2. Servicing
- 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
authorises their competence to handle refrigerants safely in accordance with an industry
recognised assessment specification.
- Servicing shall only be performed as recommended by the equipment manufacturer.
Maintenance and repair requiring the assistance of other skilled personnel shall be carried
out under the supervision of the person competent in the use of flammable refrigerants.
Do not use means to accelerate the defrosting process or to clean, other than those
recommended by the manufacturer.
The appliance shall be stored in a room without continuously operating ignition sources
(for example: open flames,an operating gas appliance or an operating electric heater)
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
Be more careful that foreign matter(oil, water,etc) does not enter the piping. Also, when
storing the piping, securely seal the opening by pinching, taping, etc.
For indoor units, use R32 flareless joint assy only when connecting the indoor unit and
connecting piping(when connecting indoors). Use of pipes, flareless nut or flare nuts other
than specified, may cause product malfunction, burst piping, or injury due to high internal
pressure of the refrigerant cycle caused by any inflow air.
