Filling the internal refrigerant
tank
Before the ACS 151 can be used, the internal refriger-
ant tank must be filled with R134a.
R134a can be procured from the local gas supplier. It is
normally stored and transported in tanks with connec-
tion fittings.
If cylinders without dip tube are used, the liquid ports
of the external cylinders should be connected to the
internal refrigerant cylinder. The cylinder should be
placed in an inverted position during the filling process.
If external cylinders with dip tube are used, the cylin-
ders can be placed in an upright position.
1. Apply the brakes on the front wheel.
2. Connect the adapter to the connection on the
external refrigerant tank.
3. Connect the HP quick coupler of the ACS 151 to the
connecting adapter on the external refrigerant tank.
