Thanks for pointing out just how stupid the HP switch is on the Daikin units,, I have replaced so many and every time I just shake my head in disbelief as to why they designed it that way where it requires a gas removal process..Yet the HP sensor switch can be removed in minutes by screwing off and screwing back on..
How did u manage to get the last of the gas in? I though the last would go in the suction when on?... I'm trying to learn ac, just incase iv missing something..
So after evacuating the system, I weigh in the refrigerant. In the perfect case, there is enough pressure in the bottle to add all the gas in. If not, then I run the system and add it slowly through the suction line. I hope that helps mate.
Hi Mitch, DAIKIN AIR WATER HIGH TEMPERATURE 16K installed in 2019 I have an error code that remains displayed: Unit 0 E3 12 160 L32 006 F5E Do you have any information regarding this recurring error code? Unit 0 concerns the outer group? Best Regards ;)
Sorry mate I don’t really understand what your talking about. Daikin E3 is a high pressure switch. Something is causing the system to have high head pressure OR the pressure switch is faulty.
It’s a high pressure switch so unfortunately the only way to diagnose this is to reset the system, and run it with some gauges on the unit. If the pressure is indeed getting to high then it could be caused by the top fan not running (if on cooling mode). However if it is coming up with this error when the pressures are fine then I’d put my money on the HPS being faulty.
