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.
