MBTEK heat pump UL or ETL approvals?

Can anyone with experience installing an MBTEK Apollo air to water heat pump post information or a picture of the UL or ETL approvals for the their unit? The product seems attractively priced but would certainly not be a bargain if it fails inspection. Thank you.

I requested that for another product of theirs and they never got back to me. The Macon I ended up buying is ETL listed.
Thanks, where did you purchase the Macon?
As info for future reference, I promptly received the attached certificate from MBTEK regarding their air to water heat pumps after my inquiry...
