Here's fifteen different codes I have either used or come across. I have two Cooltech 34788 machines. I usually buy 5 generic filters and 5 real ones at a time. I use each code twice, once in each machine. I use the generic filters when I use the code the second time.

There is no Weight in the machine. Machine show Filter weight that you have been recover refrigerant from the vehicles since last filter change! After every 68KG/150LBS of refrigerant recovery you must change the Spin-no filter. The machine ( Model-34788 ) will lock-up when filter capacity reach to 68kg & you will not abel to access the machin till replace new the filter.
When the machine show the filter weight 68kg on screen just press YES key,then add the 10 Digit code of new filter ( Code is stick with evey filter). If the code is accepted then open the old filter & replace new one.Follow the on screen direction to compleat the process.
