Overall dimension of the unit will vary if an electric heater, a
supply air plenum or a base is used.
This dimension is required for removal of the coil. Only 26" is required for normal servicing.
Although no clearance is required for service and operation,
some clearance may be required for routing the power and control wiring.
Allow enough clearance to trap the condensate drain line.
