It’s a Thursday night… and I’m watching a Gree Flexx Video. This is my life
LOL! We think you've made strong life choices...and we bet the homeowners think so too!
Mine too :-) That’s how professionals roll. Always staying up to date on changing technologies!
2:15:11 The rotary inverter compressors can run up to 7200 RPM. They need to be balanced better or redesigned so that they are quieter. No way will I ever use a wall mount bracket. again. Glad it was my own on my shop.
You guys are one of the few videos in English. I hope more manufactures learn from you guys. Keep up the good work.
Great points! GREE is the first to manufacture a true cold climate heat pump that runs the compressor at lower rpms to avoid this problem. Thanks for tuning in. You may also be interested in this video about Cold Climate Heat Pumps : ruclips.net/video/qyLDKAVZrCE/видео.htmlsi=YlfA0fv4u5nq4lje
@@GREEComfort my shop unit is an Airtemp 30.5 SEER, so the same as Gree Sapphire. That is my only issue and only in heat mode at certain RPM’s. I love the 132F supply air temperature at 20F odb. Felt like gas furnace!
Love the point on dehumidification. People are clueless on this subject
Why do you use such a non-standard filter size? It's practically impossible to find 23x20x1 filters.
I just did a ACIQ 3ton inverter handler combo not sure who makes it. It’s not the gree/Mr cool brand I’ve installed those before as well. Maybe midea 🤷
@greecomfort I am getting a P8 error code immediately upon powering on the Flexx unit. Since its considered an overtemperature protection, would it be best to replace one of the circuit boards?
I saw a UVW light tester on one of your slides. Can you tell me where to purchase one as well as EEV magnets to manually rotate the rotor? Thx.

In the service manual, 2.3.7 Forced Operation Control, it says "01" denotes that
turn on the forced operation cooling mode; "02" denotes that turn on the forced operation cooling mode. I'm assuming this is a typo and they meant to say 02 denotes heating mode? Please confirm. Will this mode also turn on the air handler blower? Thanks
Yeah has to be a typo. Ran into that today
1:46:57 you said earlier not to unplug components - specifically the outdoor fan motor when power is on. But now you’re saying to unplug components to troubleshoot as we might see the bus voltage go back up after being dragged down by a bad component. Which is it?
Cut the power and make sure the dc voltage is gone then unplug. Don’t unplug while power is still present cause it will short a board. Had it happen to me
How do I get 325cfm/ton on a 2 ton with 0.6” esp??? It looked like 840cfm or 420cfm/ton was the minimum we can set. Thx.
Thats my only issue with these systems. They have a ton of features but no dehumidification controls like many other do. It needs slower blower speeds at 2 ton and slow speed at startup then ramp up like many other brands will do.
