In the type of system I am talking about the air handler has it's own separate feed. It does not connect to the outside condenser except for the low voltage control wiring. The manufactures instructions do not show a disconnect either. Now if this was a regular air handler in the attic, a disconnect would be required.
How about a breaker lock? Would that make it a "Lockable" disconnect?
Also there is no plug and cord for the unit I refer to.
