Or the next screen may be displayed…
Press START key.
The Fill Cylinder procedure will automatically transfer
refrigerant from a new cylinder of refrigerant to the
internal RHS980 charge cylinder. The value set here
will be the amount of refrigerant which will have been
transferred when the procedure stops automatically.
Enter an amount between 3 and 11 kg. The value will
be displayed as it is entered. Press
START key.
The A/C system can be checked for leaks using a
vacuum leak test. This test will pull the A/C system into
a vacuum and then pause for a period of time. During
this time, the vacuum level will be monitored. If the
vacuum level decreases, it’s an indication that the A/C
system has a leak. This screen prompts for the level of
vacuum to be drawn. Enter an amount between 15
and 25 InHg of vacuum. The value will be displayed as
it is entered. Press
START key.
This screen prompts for the length of time to monitor
the vacuum level to determine if there is a leak in the
A/C system. Enter a number of minutes between 1 and
99. The value will be displayed as it is entered. Press
START key.
A small overcharge of refrigerant is necessary to
compensate for refrigerant which will remain in the
hose after a charge procedure. Enter the number of
KG between 0 and 0.99. The value will be displayed
as it is entered. Press
START key.
The calibration of the weight scale in the RHS980 can
be easily checked using this procedure. A steel ball of
a precise weight is provided with the RHS980 for
performing this calibration check. Press
YES key.
The screen prompts to attach the steel ball to the
bottom of the machine. There is a small post which
protrudes through the bottom plate of the RHS980
(see Parts Identification at rear of this Operation
Manual). This post is magnetic. Attach the calibration
weight to this post. Press
START key.
This screen will display if the weight scale is in
calibration. Or, see next page for screen which will
display if the weight scale is not in calibration.
