RECYCLE
1. See RHS730 Setup on Page 4. Turn Main Power Switch on.
The display will show WEIGHT= XX.X LB AUTOMATIC? 5
2. Attach Red and Blue Hoses to the A/C System per the vehicle
manufacturer's instructions. Open the Red and Blue Hose Valves.
3. Press the
>
key one time to display WEIGHT= XX.X LB RECYCLE? 5
and press the ENTER key. The Display will read RECYCLE HOLD TIME
XX MIN 5.
The Recycle Hold Time is the amount of time that the RHS730 waits
for out-gassing or for the pressure in the A/C System being recycled to
rise enough to automatically restart the recycling process. The
minimum time is two minutes. The value entered is stored in the
memory of the RHS730 and is displayed as the default value next time.
4. Press the
>
key to change the value of the field. Press the
<
key to move
to a different field. Press the ENTER key to accept the value. The Display
will then read START? 5.
5. Press the ENTER key to start recycling.
The Display will read WEIGHT= XX.X LB COMPRESSOR ON. The
RHS730 will recycle refrigerant from the A/C system and automatically
cycle OFF when a vacuum is sensed. This vacuum level can be seen
on the Low Pressure Gauge. The Display will read WEIGHT= XX.X LB
COMPRESSOR OFF.
A small quantity of refrigerant will probably remain in the A/C system
as observed by an increasing pressure on the Low Pressure Gauge.
The RHS730 will automatically cycle on to continue recycling
refrigerant if pressure rises to a preset level. This automatic cycling will
repeat, resetting the Recycle Hold Timer each time. When the RHS730
remains off for the duration of the Recycle Hold Timer value entered in
Step 4, the Display will read AMOUNT RECYCLED= XX.X LB 5 and
the Attention Light will turn on.
6. Close the Red and Blue Hose Valves and disconnect the hoses from the
A/C system.
7. Press the ENTER key. The Display will read DRAIN RECOVERED OIL
NOW! 5. Drain any recovered oil using the Drain Recovered Oil
procedure on Page 7.
8. Press the ENTER key to return to the Main Menu.
* This screen will display if there is an internal fault. Turn the RHS730
Main Power Switch off. Contact RTI Technical Support.
** This screen will display if the charge cylinder fills to capacity of
approximately 24 lbs (11 Kg.). If this occurs, the weight must be
lowered using the Charge procedure on Page 9 before the RHS730
can be used to recycle more refrigerant. Press the ENTER key to
return to the Main Menu.
