IMPORTANT NOTE: To ensure proper operation of a Model RHH, the opening through the roof must be the same
area as the inside dimension of the roof curb. Inside area of the roof curb under a Model RHH must be open.
*Configuration may also include an evaporative cooling module. The evaporative cooling module does not affect the length of the
roof curb.
