Cautions for using R32/R290 refrigerant
Installation (Space)
- That the installation of pipe-work shall be kept to a minimum.
- That pipe-work shall be protected from physical damage.
- That compliance with national gas regulations shall be observed.
- That mechanical connections shall be accessible for maintenance purposes.
- In cases that require mechanical ventilation, ventilation openings shall be kept clear of
obstruction.
- When disposing of the product is used, be based on national regulations, properly processed.
-The appliance shall be stored in a well-ventilated area where the room size corresponds
to the room area as specied for operation.
-Spaces where refrigerant pipes shall be compliance with national gas regulations.
2. Servicing
- Any person who is involved with working on or breaking into a refrigerant circuit should
hold a current valid certicate from an industry-accredited assessment authority, which
authorises their competence to handle refrigerants safely in accordance with an industry
recognised assessment specication.
- 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 ammable 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 ames,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 areless joint assy only when connecting the indoor unit and
connecting piping(when connecting indoors). Use of pipes, areless nut or are nuts other
than specied, may cause product malfunction, burst piping, or injury due to high internal
pressure of the refrigerant cycle caused by any inow air.
Appliance shall be installed, operated and stored in a room with a oor area larger than
X m² (Please see the following form ). The appliance shall not be installed in an
unventilated space, if that space is smaller than X m² (Please see the following form ).
