² 460-v motors are 2-speed.

Air delivery values are based on operating voltage of 230-v. or 460-v., dry coil, without filter or electric heater. Deduct wet coil, filter, and electric heater pressure drops to obtain external static pressure availabe for ducting.

Do not operate the unit at a cooling airflow that is less than 350 cfm for each 12,000 Btuh of rated cooling capacity. Evaporator coil frosting may occur at airflows below this point.

Dashes indicate portions of the table that are beyond the blower motor capacity or are not recommended.

mild detergent-and-water-solution. Rinse coils with clear water, using a garden hose. Be careful not to splash water on motors, insulation, wiring or air filter(s). For best results, spray outdoor- coil fins from inside to outside the unit. On units with an outer and inner outdoor coil, be sure to clean between the coils. Be sure to flush all dirt and debris from the unit base.

Inspect the drain pan and condensate drain line when inspecting the coils. Clean the drain pan and condensate drain by removing all foreign matter from the pan. Flush the pan and drain tube with clear water. Do not splash water on the insulation, motor, wiring, or air filter(s). If the drain tube is restricted, clear it with a ``plumbers snake'' or similar probe device. Ensure that the auxiliary drain port above the drain tube is also clear.

Step 5ÐOutdoor Fan

Keep the Outdoor fan free from all obstructions to ensure proper cooling operation. Never place articles on top of the unit. Damage to unit may result.

1.Shut off unit power supply and install lockout tag.

2.Remove outdoor-fan assembly (grille, motor, motor cover, and fan) by removing screws and flipping assembly onto unit top cover.

3.Loosen fan hub setscrews.

4.Adjust fan height as shown in Fig. 21 or 22.

5.Tighten setscrews.

6.Replace outdoor-fan assembly.
