When choosing the proper model Draw
Thru Air Handler, primary consideration should be given to
calculated BTU loads and available power supply.
AH-DT2 series air handlers are
ductable units, designed to be installed low in cabin areas (under
berths, lockers, etc.) and ducted to high supply air grilles. These
units have rotatable blower-motor assemblies, providing flexibility
to fit specific space requirements and allowing for proper duct work
installations. Combinations of transition boxes may be used to
supply air into more than one area from a single unit.
Securely fasten the AH-DT2 to a solid,
level surface, using the four (4) mounting rails provided in the
base. Rotate and secure the blower, if necessary, to its proper
position to provide the most direct routing of the ducting to
transitions and supply air grilles. Rotate and secure the blower, if
necessary, to its proper position to provide the most direct routing
of the ducting to transitions and supply air grilles. Route all
ducting to be as smooth and straight as possible. Trim off excess
ducting before making final connections. Secure the ducting every
48" (min..) to prevent movement while the vessel is under
The return air inlets must be properly
sized and located to allow adequate return air flow to the units. A
clip-on type return air filter is supplied standard with each unit.
These filter assemblies should be checked periodically and cleaned
when necessary. Return air grilles should not be located in such a
way as to allow the supply air stream to blow directly into its
opening. This will cause "short cycling" of the unit,
resulting in poor performance.
