Setup
Fill the Internal Storage Vessel (ISV)
1 . Press START / YES, and the unit
automatically runs a 5-minute vacuum to
clear all internal air.
Note: The “burping” noise heard during this
process indicates air is being purged from the
system—this is normal.
2. After the vacuum pump shuts off, connect
the fill hose to the liquid connector on a
full source tank.
3. Open the source tank valve.
4. Install the source tank, and secure it to
the unit (using the tank strap) in such a
way that liquid refrigerant is supplied to
the connection.
5. Press START / YES to begin filling the
internal storage vessel. Add at least 8 lbs.
(3.6 kg) of refrigerant to ensure enough
refrigerant is available for charging.
This process takes 15–20 minutes. The
unit stops when a sufficient amount of
refrigerant has been transferred to the
internal tank, or when the source tank is
empty.
Press STOP / NO to pause. Press STOP
/ NO again to exit, or START / YES to
resume.
6. When the fill process is complete, press
STOP / NO to exit. The unit is ready for
operation.
Note: There is no need to calibrate the
scale; it is calibrated at the factory.
