Installation Guidelines for slim line air handler 6K-12K

When choosing the proper model Slim Line Air Handler, primary consideration should be given to calculated BTU loads and available power supply.

Slim Line Series air handlers are designed to be direct-discharge or ductable units. Air flow can be supplied to more than one area through the use of properly sized plenums, transitions and ductwork. The SL2 configuration allows for installation in tight areas (shipside panels, narrow bulkhead spaces, short overheads, etc.) in either horizontal or vertical positions.

Securely fasten the slim line air handler units to a solid level surface using the four (4) mounting holes provided in the base. The supply air outlet must be sealed properly either through cabinetry for direct-discharge, or into a plenum for a ductable discharge. All ductwork is to be routed as smooth and direct as possible. Any flexible ducting is to be secured every 48" (minimum) to prevent movement while the vessel is under operation. Trim off excess ducting before making final connections.

The return air inlet(s) must be properly sized and located to allow adequate air flow into the air handler. The SL2 series air handlers have factory installed, removable filters to trap dust and other airborne particles. Return air inlets 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 or inadequate performance.

The supply air grille(s) must be sized and located to allow for proper air circulation within the cabin area(s). Grille locations close to the ceiling, or directed upward, provide the best air circulation. Undersized grilles and plenums, along with any crushed or kinked ductwork, 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. The drain line must be routed downwards to a proper sump or overboard discharge. Properly secure the drain lines to prevent movement or lifting 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 overhead in lockers to prevent sweating of the line , which could cause water damage.

Water connections from the circulation circuit to the unit are to be reinforced flexible hose and double clamped, direction of clamps should be reversed. 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.

All wiring must be sized according to marine design standards. Only stranded, tinned copper wire is to be used. All electrical connections to the air handler are to be made inside the electrical junction boxes provided on the assembly. All units must be properly grounded.
