Anleitung Zusammenfassung
This accessory is designed for indoor installations in either upflow or horizontal air discharge applications. This unit is for use only on R.410A systems with thermal expansion valves. Prior to installation, study the decision tree on page 16 to confirm that all application requirements for EDA installation are met. NOTE . For downflow application, refer to Installation Instruction Supplement, Installing EDA Unit in Downflow Configuration 505,134M. Shipping & Packing List . 1 . Assembled EDA indoor unit . 1 . Bag assembly (includes check/flow restrictor for use on EDA coil, EDA notification label). . 1 . Outdoor fan relay and wiring harness (used only with outdoor units equipped with variable speed fan motors) Check the components for shipping damage. If any damage is found, immediately contact the last carrier. Other Required Components Separately-ordered components are restricted to those listed in the Engineering Handbook and the price book: .

These instructions are intended as a general guide and do not supersede local codes in any way. Consult authorities having jurisdiction before installation. The Humiditrol® EDA unit will operate to dehumidify, as required, when ambient temperatures are below 95.F. When temperatures reach 95.F, the cooling and dehumidification requirements will both be satisfied by the increased system runtime. In applications that include a Humiditrol® EDA unit, a call to activate the dehumidification mode at or above 95.F is unnecessary and would not be issued or allowed by the SignatureStat room thermostat. Prior to system checkout, consider the outdoor ambient temperature. REMEMBER, the EDA unit does NOT function in temperatures at or above 95.F. Plan testing to be conducted when temperatures are between 65.F and 95.F to ensure proper EDA set up and checkout operation. IMPORTANT The approved application for the EDA Series unit is restricted to those listed in the Engineering Hand- book and price book. 505,021M . WARNING Risk of explosion or fire. Can cause injury or death. Recover all refrigerant to relieve pressure before opening the system. WARNING This cased product contains fiberglass wool. Disturbing the insulation during installation, maintenance, or repair will expose you to fiberglass wool dust. Breathing this may cause lung cancer. (Fiberglass wool is known to the State of California to cause cancer.) Fiberglass wool may also cause respiratory, skin, and eye irritation. To reduce exposure to this substance or for further information, consult material safety data sheets available from address shown below, or contact your supervisor. Lennox Industries Inc. P.O. Box 799900 Dallas, TX 75379.9900 IMPORTANT The Clean Air Act of 1990 bans the intentional vent- ing of refrigerant (CFC’s, HFC’s, and HC...
