I've been following this channel for a while now and i have to say Quentin is quite brilliant. It would be great to train under a technician like him. Keep these videos coming guys.
I am just continuously impressed with the professionalism in these videos! You guys really know what you are talking about and, even better, you know how to convey that to the everyday Joe, or Jane, to help them understand the content. Keep up the great work!
If you’re searching the comments wondering how does taking 91° from 27° = 36° 🤔 Just keeping you on your toes 😉 I meant to say: 91° from 127° = 36° of Discharge superheat Remember: Discharge pipe temp - Condenser Temp (Tc) = Discharge Superheat Suction pipe temp - Evap Temp (Te) = Suction superheat Like and subscribe to see what we put out next!
Thanks for sharing this video . I have been too all of the Daikin Training that’s offered and unfortunately they have not went over valuable information like this . This reinforces the knowledge that I have learned in the field through OJT ..
Almost all indoor units utilize a bolt-on style valve driver motor. The valve will go 100% open with the driver motor removed. If the EEV has a slip-on (coil) style driver, the valve will remain in whatever position it was in before the coil was removed.
@@quentinbutlerhvac5410 thank you,it makes more sense to me now. What about if you disconnect the LEV plug from the PCB (or cut the power to the system), will the valve body stay in the same position? Is the outcome different depending on whether the LEV is bolt on or clip on?
@@LC-qi5ff Another great question! If you power down the system or unplug the EEV, the valve will remain in its last position due to the construction of the valve. We will make a video on the internals of the EEVs used on VRV to provide additional clarity. Thanks for watching!
If you’re only replacing a FCU, you don’t need to run a test, but you should conduct a system recount. To conduct the system recount, press and hold the return button at the master outdoor unit for 5 seconds - 3 small squares should populate on the 7 segment LCD display during the system recount. If the existing FCU that is being replaced had a Group Address and/ or an Airnet address, input those addresses into the new indoor unit.
@@MechanicalPros sir my Clint have bee using Daikin VRV 4 system 3. But currently system break down so I have replace 3 fancoil . After replacing how to test up that’s all
Another way to check for bleed by is to put the system in forced operation, all indoor fan coils except 1 or 2 in fan mode. Put the 1 or 2 in cooling. Then watch the indoor fan coils, if you get a temp drop across those fan only eevs your bleeding by. We see this alot- probably dirty install
So my United Refrigiration sold me d-checker with empty software cd & said it can't help me anymore & daikin is helpless when trying to contact them they kuat keep saying contact your rep, I REALLY NEED THE SOFTWARE HOW DO I GET IT

Thank you @shannonedwards1872 !
Thank you gents. Definitely need more training on the Daikin checker so videos like this are a god send
You’re welcome! More to come!
Thank you Quentin, keep them coming 💪🏼💪🏼💪🏼💪🏼
It is our pleasure, David! Thanks for watching!

He made mistake...He meant 127 ;) Look at the cheker

Glad it was helpful!
Excellent video. What is the eev’s default position, say when the head has been removed? Thank you

Please make more videos about troubleshooting VRV’s using the service checker.
@@MechanicalPros do you have a service checker file that you recorded where it shows a stuck 4 way valve or faulty main EEV on the outdoor unit?
I wish you could use this tool on the normal Daikin Split system not just VRV..
Hi sir I hav daikin vrv 4 but I have to change only fcu . So how to test run please pm me
