Page 8 1. Installation(where refrigerant pipes are allowed) - 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. - 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.
Page 9 design pressure and the minimum test pressure for the high side of the system shall be the high side design pressure, unless the high side of the system cannot be isolated from the low side of the system in which case the entire system shall be pressure tested to the low side design pressure.
Page 10 NOTE Examples of leak detection ﬂuids are - bubble method, - ﬂuorescent method agents. If a leak is suspected, all naked ﬂames shall be removed/extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system, or isolated (by means of shut o valves) in a part of the system remote from the leak.
Page 11 Explanation of symbols displayed on the indoor unit or outdoor unit This symbol shows that this appliance used a ﬂammable refrigerant. If the refrigerant is leaked and exposed to an WARNING external ignition source, there is a risk of ﬁre. This symbol shows that the operation manual should be CAUTION read carefully.
