1This dimension will vary if an electric heater, a supply air plenum or a base is used.
2This dimension is required for normal installation and service.
3Although no clearance is required for service and operation, some clearance may be required for routing the power and control wiring.
4Allow enough clearance to trap the condensate drain line.
Note: If the coil has to be removed, the blower section can be unbolted and set aside and the coil can be lifted out the top of the evaporator section.
