Refilling the Automotive System with Oil and Refrigerant
Vehicle manufacturers design for and specify a specific amount of refrigerant for 1.
best operation of your vehicle A/C system. This amount is specified in weight. Too
much or too little refrigerant will adversely effect the operation of the A/C system.
Some newer vehicles will shut down the A/C system if too much refrigerant is in
the system.
After recovery, check the amount of used oil separated from the automotive sys-
2.
tem, and be sure there is at least 20 ml more new oil in the New Oil bottle than the
amount removed. If there is not enough oil in the bottle, close the Oil Charge Valve
(I-9) and add oil to the new oil bottle.
Check to be sure the HP and LP valves on the Control Panel are open.
3.
Slowly open the Oil Charge Valve (I-9) allowing new oil to be sucked into the au- 4.
tomotive A/C system. Do not open the valve all the way, rather, use it carefully to
control the flow of oil. Allow oil to flow into the system until 10 ml more than the
amount removed has been added back.
When sufficient oil has flowed back into system, close Oil Charge Valve.
5.
Press the “Refilling” Key on the Control Panel. The machine will begin to replace 6.
refrigerant in the vehicle A/C system. The Refilling Indicator light will be on.
NOTE: If the refilling process is taking too long, you can speed the process by using
7.
the vehicle A/C compressor. Turn off the HP valve on the machine Control Panel.
WARning! never turn the vehicle A/C system on if the hp valve is open. Turn the
vehicle A/C system on. The refilling process will go faster.
After system has been completely refilled, the machine will stop automatically.
8.
Close both the HP and LP valves on the Control Panel. Move the Power Switch to 9.
the OFF position. If the vehicle A/C system is running, turn it off.
Slightly loosen the hose connector, allow a few seconds to stabilize any existing pres-
10.
sure in the hoses, and then back off the hose connectors and remove the hoses.
Always test the vehicle A/C system before returning the vehicle to the customer.
