Fitting/installation
The arrow on the valve housing indicates the direction of the flow.
The male thread has to be sealed in the usual manner.
To avoid condensate precipitation and possible icing, the combination valve should be insulated with the accompanying insulation.
On filling with refrigerant
Close valve 1. Connect the refrigerant fill to valve 3 according to the flow arrow. Connect the refrigerant return to valve 4. After filling, close the filling valves 3 and 4, open valve 1.
Cleaning the filter
Close the valves 1 and 2, unscrew the filter cover 5, clean the filter. When refitting, the tap below the filter holder should be fitted in the hole provided in the filter housing. Fill with a few centiliters of refrigerant to prevent air entering the system.
