You are done. Enjoy your cooler. NOTES: • When switching to low cool, you must rebalance your home. Repeat step 4. • Once you balance your home you can cool some areas more than others by opening those windows more and closing the others by the same amount. Repeat step 4 to make sure your home is still air balanced. Installation NOTE: The pump comes installed. The belt, motor pulley, and motor cord and float are included in the cabinet, the motor is shipped separately. A\CAUTION: Make sure that the mounting surface is strong enough to support the operating weight of the cooler when in use. (For operating weight, see Specification Table.) ^CAUTION: Never plug in cooler until installation is complete and unit has been tested for rigidity. Junction Box Install Duct Adapters. If desired, a 4 piece duct adapter is available as an optional accessory. Call 1-800-643-8341 to obtain these from the factory. Align the holes in the duct adapter to the holes in the blower opening and attach using the provided screws (see Fig. 1). Repeat for all four sides. Note: All 4 pieces are identical except for models 5000SD & N55/65S which have an offset piece which attaches to the bottom of the outlet. To install this offset piece, remove the screws holding the cut-off plate and slide the offset duct adapter between the blower opening and the cutoff plate. You may need to loosen other screws to do this. Line up the holes and secure with the screws previously removed. Motor Installation • Install motor cord. For typical 120 V operation, connect motor cord to motor using the following color code: Black - Hi, Red - Low, White - Com., Green - Ground. (See Wiring Diagrams) • Mount motor. Install blower motor in the motor mount yokes, adjusting the yoke if necessary. Fasten with the provided mounting clips (see Fig. 2). • Install pulley. Install the adjustable motor pulley so that it aligns with the blower drive pulley (see Fig. 3) and tighten set screw.

See the wiring diagrams for 120V and 240V installations. Note: Clip pump cord onto cord clip located on the bottom of the junction box to keep cord our of the water. IMPORTANT: When a single speed motor is used, do not use the red lead on the receptacle and motor plug wiring.

Place drain nipple through the hole in the pan, with the rubber washer between the pan and the head of the drain nipple (Fig. 6). Screw on nut and draw up tight against bottom of pan. Insert the overflow pipe in the nipple to retain water. The overflow pipe may be removed to drain the pan when necessary. A garden hose may be screwed on the drain nipple to drain water away from your unit. Connect water supply line. Find the closest supply of water. Use a saddle valve (Fig. 7) to connect 1/4” tubing to the cold water supply or use a Sillcock and water valve connected to an outside faucet (Fig. 8). Place the nut and ferrule on the tubing and tighten the nut until water tight. IMPORTANT: Do not connect the water supply to any soft water applications. Soft wate...
