5. If the sensors need recalibrating, hold down the Mode (5) and Play (8) keys for 10 seconds.
6. During operation, you can use the up and down arrow keys (2) to jump back and forth between
the views for ambient temperature / T1 / T2 and T2-T1 / overheating / undercooling.

4. Using the ROCOOL 600 (e.g. evacuation and filling)

4.1 Evacuation and filling

1. Press the Start button for 3 seconds and make the desired basic settings (refrigerants etc.).
2. Use a charging hose to connect the system's low-pressure port to the low-pressure port (14)
of the ROCOOL 600. In the same way, if possible, connect the two high-pressure sides with a
charging hose.
3. At the middle T connector (16), you can connect the vacuum pump and the refrigerant tank
(15). So as not to create any overpressure on the vacuum pump during filling, Rothenberger
recommends using charging hoses with shut-off valves.
4. Now turn on the vacuum pump and open the route from the vacuum pump to the system to
begin evacuation.
5. As soon as a sufficient vacuum level of -0.95 is reached, the green LED starts to blink.
6. Turn the vacuum pump off.
7. If the vacuum pump is kept below -0.95 bar for 30 minutes, the green LED stays on conti-
nuously.
8. Start the filling process by opening the route from the refrigerant tank to the system.  The
route to the vacuum pump must be closed off at the charging hose.  If the maximum allo
wable pressure is exceeded during filling, the red LED starts to blink.
9. Connect the plug of the T1 temperature terminal to the connector (12) provided for the pur-
pose on the ROCOOL 600, and clamp the temperature terminal to the system's suction line to
measure superheating.
10. Connect the plug of the T2 temperature terminal to the connector (13) provided for the pur-
pose on the ROCOOL 600, and clamp the temperature terminal to the system's heating gas
line to measure subcooling.  If both temperature terminals are connected, superheating and
subcooling are shown in parallel.
11. Before finishing the filling process, make sure that there is no more refrigerant in the ROCOOL
600 or in the charging hoses.
12. If necessary, rinse the ROCOOL 600 with nitrogen and evacuate the ROCOOL 600 before
using it again.

4.2 Heat Pump Mode

The Heat Pump mode ensures the automatical switch of the low-pressure and the high-pressure
port when heating with inverter units.
1. Press the up and down arrow buttons at the same time for 5 seconds to activate the heat
pump mode
 The turns into a

6. Disposal

Parts of your device can be recycled. Approved, certified recyclers are available for this. Ask your
waste authority about environmentally sound disposal of non-recyclable materials (e.g., electronic
waste). Never throw used replacement batteries in fire or household refuse. Your dealer can dispose
of used batteries in an environmentally sound manner.
