If the units have their own breakers built in then you may not need the disconnects but you generally need a disconnect that is within sight of the AHU.

Use of AHUs are 24/7 operation, This is in the ADX superMax. so they never shut down but for service. I have talked to the maintains men onsite there ok with them being removed but bring up that when there off others come in to service the units or trouble shoot. the others are form the other prisons here.
