1. See RHS730 Setup on Page 4.Turn the Main Power Switch on.
2. Attach the Red and Blue Hoses to the A/C system per the vehicle
manufacturer's instructions and open the Red and Blue Hose Valves.
3. Determine the refrigerant capacity of the A/C system to be charged.
1 oz = 0.02835 Kg 1 Lb = 0.45359 Kg
4. Press the
>
key three times to display WEIGHT= XX.X LB CHARGE? 5
and press the ENTER key. The Display will read ENTER CHARGE
AMOUNT= XX.X LB 5.
5. Press the
>
key to change the value of the field. Press the
<
key to move
to a different field. The value entered must be greater than zero. Press the
ENTER key to accept the value. The value entered is stored in the
memory of the RHS730 and is displayed as the default value next time.
The Display will read CHECK HOSES 5.
* This screen will display if the RHS730 charge cylinder contains less
refrigerant than the entered value. When this occurs, the charge
cylinder should be filled using the Fill Cylinder procedure on Page 5.
Press the ENTER key to return to the Main Menu.
Refrigerant is usually charged to the high side of an A/C system
through the Red Hose. The Blue Hose can be connected to the
high side port (where Red Hose is normally connected) if it is
desired to charge to the low side of the A/C system. This should
only be done if the vehicle manufacturer specifies charging to the
low side.
Do not turn on the A/C system.
SAE compliant refrigerant handling stations, like the RHS730,
charge refrigerant in the liquid phase. Adding liquid refrigerant to
a running A/C system may cause immediate A/C compressor
failure.
6. Press the ENTER key to start charging.
The Display will read WEIGHT= XX.X LB CHARGING as refrigerant
leaves the Charge Cylinder. The weight displayed will increase from
zero to the charge amount entered in Step 5 plus a one ounce (0.03
Kg) over charge set at the factory to compensate for refrigerant left in
the hoses (See Set Over Charge Amount on Page 14 to change the
default value). When the RHS730 has finished, the Display will read
CHARGE COMPLETE EVAC HOSES 5 and the Attention Light will
turn on.
7. Press the ENTER key to return to the Main Menu. The A/C system can
now be turned on and tested by monitoring the High and Low Pressure
Gauges.
8. Close the Red and Blue Hose Valves. Disconnect hoses from the A/C
system and go to Page 6 (Recycle) to evacuate the refrigerant from the
hoses.
