Carefully read the instructions
Working on components with safety-relevant functions jeopardises the safe op-
eration of the installation. In case it is necessary to replace components, only
use approved parts from GREE Electric, the Original Equipment Manufacturer
(OEM) or Gree released or authorised components. The system contains the
refrigerant R-290 (propane). This condition requires special safety precautions
to be observed. While working on the system, the presence of any kind of igni-
tion sources (e.g. sparks, open flames, hot surfaces, static electricity) are strictly
prohibited. At the installation site, no matter what kind of activities are executed,
smoking is strictly prohibited!
Likewise, ensure the installation site is well ventilated. For further details on the
handling of the refrigerant R-290 see also pages 11 and 41.
Do not charge the system with any refrigerant which is not R-290! Do not mix
any refrigerants! Before filling the system, ensure that there is no air (or other
non-condensable gases such as nitrogen) left in the system, otherwise there is
severe danger of damage to the system caused by excessive high pressure.
After charging the system with refrigerant, carefully examine and confirm the
tightness by the use of an appropriate electronic leak detector!
