Refrigerant filling
After the vacuum is qualified, close the high
and low pressure valves at the same time,
connect the Yellow pipeline to the bottle
opener, and then screw the bottle opener
into refrigerant R134a, rotate the bottle
opener to pierce the refrigerant bottle, and
then rotate the bottle opener to release the
refrigerant. (at this time, the red and blue
switches of the high and low pressure
meters are all closed), the air in the
maintenance pipeline can be discharged,
and the refrigerant can be seen to be
ejected.
Note: The weight of the refrigerant of single
row vehicles and double row vehicles is
different. The single row plus is 400g, and
the double row plus injection is 450g.
Please find professionals for operation
when you add a bet.
High port filling
Turn on the high-pressure filling knob (red),
and fill with high-pressure. At this time, the
refrigerant is added into the system as a
liquid (refrigerant bottle is inverted), and
a bottle (220g) is added. In this process, it is
forbidden to start the air conditioning
system. After filling, close the high-pressure
filling knob.
Low port filling
Take off the bottle opener slowly to prevent
frostbite caused by the rapid ejection of
residual refrigerant. Replace the new
refrigerant bottle, repeat the above
refrigerant opening and exhaust process,
turn on the low pressure filling knob (blue),
and keep the high pressure (red) closed. At
this time, the refrigerant is added into the
system in gaseous state. Keep the
refrigerant bottle upright, start the air
conditioning system, and adjust the blower
to the maximum, maintain the idle state.
