Procedure Safety point
Jigs and
tools
1 Plug the power supply cord of the main unit.
2 Connect the coupler of the high-pressure side (red hose) and the
low-pressure side with the compressor main body sequentially.
Purge residual pressure before connecting because the
connection of coupler becomes firm if there is residual pressure in
the unit.
(Usually it has been performed at work end. Refer to Flow No.14.)
Be careful to the
scaffold
3 Attach all freon cans. (6 cans)
Tighten as it is though the gas leaks a little when attaching. Be careful that gas
liquor does not splash
4 Turn ON the automatic gas sweep switch. (to increase degree of
vacuum)
(If the gas is insufficient, turning OFF is allowed.)
5 Set the time switch to "20 minutes".
(Set to longer period if there is a time.)
6 Turn the power switch to the automatic side. (starts vacuum)
7 Vacuum operation is finished when the buzzer sounds 15-20
minutes later. Starts gas charging.
8 Engine start is allowed when buzzer sound stops. (Turn ON the air
conditioner switch.)
(Keep idling for at least 10 minutes --- specified by DENSO.) Make sure to check
surroundings
9 Turn OFF the power switch when the gas disappears from the
remainder gas sight glass of the main unit.
10 Check the air-conditioning capability
Temperature control: : Maximum cool
Blower: : Hi
Engine speed : Approx. 2000 rpm
The blowing temperature must be in the graphic chart value.
(Refer to the graphic chart.)
(Near the outside air temperature scale in the gauge is a standard
pressure.)
11 Stop the engine Pull out the key
12 Wait for two minutes until pressure falls, and detach the
high-pressure side and low-pressure side quick couplers. Be careful to the
scaffold
13 Test gas leakage. (for all hose connections)
(Check the gas leakage from the lower side because the freon is
heavier than air.)

14 Detach the empty gas can, and purge pressure in the hose.
1) Set the timer knob to the vacuum side.
2) Set the power switch to the automatic or manual.
3) Turn OFF the power switch when the high/low-pressure gauge
indicates approx. "0" pressure-value after a few seconds.
15 Finish the work.
Unplug the power supply cord, and put away the gas charge unit.
