Requirements for use
It should be an explosion-proof vacuum pump that
can ensure certain precision and its vacuum degree
should be lower than 10Pa.
It should be a special explosion-proof filling device,
have certain precision and its filling deviation should
be less than 5g.
It should be calibrated regularly, and its annual leak
rate should not exceed 10g.
A) The maintenance site should be equipped with a
fixed-type combustible refrigerant concentration
detector and connected to a safeguard alarm
system; its error must not be more than 5%.
B) The installation site should be equipped with a
portable combustible refrigerant concentration
detector which can realise two-level audible and
visual alarm; its error must be not more than 10%.
C) The concentration detectors should be calibrated
regularly.
D) It is necessary to check and confirm the functions
before using the concentration detectors.
The pressure gauges should be calibrated regularly
(a pressure gauge used for R410A can be used for
refrigerant R32).
It is necessary to carry fire extinguisher(s) when
installing and maintaining an air conditioner. On
the maintenance site, there should be two or more
kinds of dry powder, carbon dioxide and foam fire
extinguishers. Such fire extinguishers should be
placed at stipulated positions, with eye-catching
