If a field-installed mixing box is that unit is level when hanging from the ceiling). Where the attached, adjust to balance the unit properly.
Installation Panels and Doors Actuators DANGER CAUTION Hazardous moving parts, high static pressure, and/or high voltage. Can Maximum damper rotation is 70°. Maximum shaft torque is 205 in.-lb. cause severe injury or death. Disconnect and lock ALL electric power OFF Greater rotation or torque can cause equipment damage.
Installation Installing Damper Actuator Figure 9: Actuator Manual Override Button and Strap 1. Turn the damper shaft until the blades are fully closed. 2. Place the actuator’s universal clamp over the damper shaft (Figure 8). Make sure that the controls on the actuator cover are accessible.
Installation Reversing the Coil Handing Depending on whether the air handler was purchased from CAUTION stock or if it was manufactured for the specific job, the Sharp edges and coil surfaces can cause personal injury. Avoid contact panel on the opposite side may or may not have predrilled with them.

Installation Reversing the Belt Drive Package Hanging the Unit from a Ceiling A motor side or “hand” is determined by looking in the direction WARNING of air flow with the air contacting the back of the head. The drive Do not suspend the unit from the top. The unit top will not support the weight package on the air handler can be changed to the other side of of the unit.
Installation Piping and Coils Direct Expansion Coils Follow applicable piping design, sizing, and installation information presented in ASHRAE Handbooks in the design Direct expansion coil connection guidelines are listed below. and installation of piping. Observe all local codes and industry Also, refer to Figure standards.
Installation Steam Coils (provided as Specials only) Steam coil connection guidelines are listed below. Also, refer to Figure 17: Steam Coil Connections (Type SS) Figure 1. All steam coils are non-distributing (freeae) type. They are not designed to be used in 100% OA applications. 2.
Installation Water Heating Coils Drain Pan Traps Heating coil connection guidelines are listed below. Also, refer Destiny air handlers have a drain pan connection on both Figure 18 Figure sides of the unit. Drain connections can be made on either side or both sides.
Installation Internal Isolation Assembly Spring Mount Adjustments—Twin Fan Units Adjustment The spring isolators under the four corners of the fan and Units have internally isolated fan and motor assemblies that motor assembly have been factory adjusted while the fan was are secured with brackets for shipment.
Installation Electric Heat Section (Optional) Optional factory installed electric heat section consists of Figure 23: Heater Nomenclature open coil duct heater mounted to the unit at the supply fan C M XX - XX - X X discharge. Heat section includes heating coils and an electrical control box with single point field power connection for heater and supply air fan.
