Care And Maintenance; Customer Service - Rothenberger ROREC Pro Digital Instrucciones De Uso

 Ensure that the operating button is set to the position "Recover".
 Open the outlet connection of the plant.
 Open the high pressure connection on the manifold (if connected). Opening of the liquid
connection has the effect of the liquid being removed from the cycle. After removal of the
liquid, for complete emptying of the plant, open the high pressure connection on the mani-
fold.
 Close the plant at a suitable outlet (see type plate on the plant).
 Press the "On/Off button" in order to start the compressor.
 Leave switched on until the desired pressure has been established and the device switches
itself off.
 Close the low and high pressure connections on the manifold.
 Turn the unit off.
 Close the inlet connection of the unit and proceed with the self-emptying as described in the
next section.
ATTENTION: Empty the device after every use. In the case of non-emptying of the
refrigerant residues, damage can occur to internal components due to acid and
therefore the service life of these components is shortened!
Self-emptying procedure for removal of refrigerant residues from the recovery unit:
 Slowly turn the operating button to the PURGE position and leave the plant switched on until
the desired pressure is achieved and/or the internal pressure switch-off switches off auto-
matically.
 Close the connections of the recovery bottle.
 Interrupt the power supply, remove all hoses and dry the filter.
 Turn the operating button to the CLOSE position.
 In the last step cover the cap on the inlet and outlet connection.
Push/Pull method for liquids:
The Push/Pull method is only used for large plant in which there is at least 10 kg of liquid refrig-
erant.
ATTENTION: A pair of scales must be used for the "Push/Pull" method in order to
prevent overfilling of the disposal bottle itself when the bottle is fitted with a float fill
level indicator!
 Turn the operating button to the RECOVER position.
 The recovery process is switched off automatically on the occasion of going below the max-
imum vacuum value. Then change directly into PURGE mode.

Care and Maintenance

In order to achieve a long service of life and a high efficiency of the extraction unit, please
change the filter regularly. Also only just use one refrigerant for each filter.
