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 operation.

The supply air grilles must be sized and located to allow for proper air circulation within the cabin area(s). Grille locations close to the ceiling or directed upwards provide for the best air circulation. Under sized grilles and crushed or kinked duct work will result in poor or inadequate air performance.

Both condensation drain lines must be connected to the air handlers' two (2) drain pan spuds using reinforced flexible hose (5/8") and clamps. The drains may be teed together, providing there is a minimum drop of 2" from the drain pan to the tee fitting(s). The drain line must be routed downwards to a proper sump or overboard discharge. Properly secure the drain lines to prevent movement during vessel operation. Check the drains upon completion by pouring two (2) quarts of water into the drain pan. NOTE: Condensation drain lines may need to be insulated when located in high heat load areas to prevent line sweating, which could cause water damage.

Water connections from the circulation circuit to the air handler are to be reinforced flexible hose clamps. Attach the hose to the 5/8" hose barb fittings on the water inlet and outlet of the unit. All hose, pipe and connections must be insulated properly to prevent condensation. Use approved closed cell tube insulation (1/2" minimum) on the hose, and foam tape on the fittings (5-6) wraps.
