Guys, do I need to remove the white cover? The manual doesn't say anything.

Dont mention then why you bother?

Only do what was asked in the manual. Stainless steel hook? Wow...

Okay finally completed installation of the Bayu fan.

Sadly, the fan might be defective.

1. It briefly spins backwards, before spinning forwards when turned on
2. When switching speeds, it takes around 10 seconds before applying the new speed. It's not instant, there is some delay there

Can someone confirm if this is indicative of a defective unit?

old fan are worth to fix. new 1 very nipis and quality so so only unless pay premium.
