Mitsubishi Electric / Fan Replacement on a PUHZ-YKM & Static Pressure Measurements

Returned to site to carry out static pressure measurements and adjust the dip switch settings accordingly. Then, returned with the outdoor fan to replace. Trying to make the best of a bad situation with this install.

Awesome video!

I think generally to get a reasonable static pressure reading it has to be taken 5 (unsure of exact number) duct diameters downstream from elbows or anything that would cause turbulence.

I appreciate that you originally thought the static would be wicked high, but actually came back to test it to confirm and was lower than you thought. Some people would just say "it's cooked" without testing.

WTAF were they thinking with the ducting....is it some stupid attempt at beauty at the expense of working A/C units....

[@electroshed]

Let's just say hypothetically they replaced those acoustic louvre wall grilles for just mesh fencing, pretty much see through - would the increased airflow lead to a reduction in noise, and would the noise levels from outside the compound be about the same as they were with the acoustic walls and units running balls out? food for thought :)

What a balls up of a job that was!. Probably starving the condensers of air aswell that many condenser in one spit and shitty fresh air flow

The exit point for the added ducts looks heavily restricted by the slats going across. They should have cut them and put a grill in place.

that looks like the worlds biggest shit show
