Precautions for using R410A
refrigerant devices
Please supplement
refrigerating system with liquid
refrigerant. In the case of
gaseous refrigerant,
composition of refrigerant in
the system may change.
Do not mix into other
refrigerants.
Do not use the following tools
ever used for common
refrigerants (such as R22):
pipeline pressure test devices,
charge hoses, leakage
detection devices, refrigerant
charge base, and refrigerant
recovery devices.
Make sure to use vacuum
pump dedicated for R410A
series.
Precautions at trial operation
When the system is powered
on for the first time or after
being left unused for a long
time, ODU power must be
connected 24 hours before
use. Otherwise, the
compressor may be burnt
(make sure the air
conditioner is in standby
mode at the seasons they are
needed most).
Do not turn on the air
conditioner when the panel or
protection screen is removed.
The moving parts inside the
air conditioner may hurt
people or other objects.
Do not touch refrigerant
pipeline during operation or
just at the end of operation.
The pipeline of the air
conditioner may be very hot
or cold during its operation,
which may lead to scald or
frostbite.
Do not turn off power
immedia
tely after the unit
stops. Wait at least for five
minutes to prevent water
leakage.
Please cut off general power
supply during seasons the air
conditioners are not used to
prolong the service life and
save energy.
All the IDUs and ODUs of the
same syst
em must be
supplied with power
simultaneously.
