Aquacal sq225 heat pump wiring

[anthony21078]

At the last step of wiring up the heat pump. I see the bond lug on the bottom part of the frame with a little ground sticker that says B. Inside the unit on the empty ground lug it also has a ground sticker for with a B.

Bond wire only goes to the bottom lug correct? And my ground wire goes to the lug inside the unit above the small green wire correct?

The bond wire is not supposed to connect to the bottom lug and then run upward to the unused lug in the unit while doubling up the ground with smaller green wire below it right?

Unless the instructions say to do it differently, the 8g bond wire goes to the external bond lug, the electrical ground goes to that internal lug. Since they are both attached to the cabinet they are actually connected through the cabinet to each other.

The B and ground symbol printed on both stickers had me confused but you clarified it. The manual I have does not go into wiring specifics.

On another note, I've been reading a lot about GFCI breakers on heat pumps and whether or not they are required or needed as per manufacturer specs. Family relative is an electrician in New York and stated all the pool equipment must have GFCI breakers. I spoke to aquacal who stated they do not recommend GFCI breakers because of the likelihood of tripping when in fact there wasn't a fault. They said when the ambient temperature typically falls below 65 there can be excessive condensation build up in the unit which can cause a GFCI breaker to trip. Aquacal said down in Florida where they are based they typically don't have this problem but in the Northeast if I decide to run the unit in colder months I can have this problem. For now I have a 60 amp GFCI in there but I have a regular 60 amp breaker on standby. Anyone have experience with this?
