CAUTION To help ensure high performance and minimize possible equipment failure, periodic maintenance must be performed Failure to perform the test run may result in unit damage, on this equipment. Maintenance frequency may vary depending on geographic areas. property damage, or personal injury. Before the Test Run Troubleshooting A test run must be performed after the entire system has been completely installed. Confirm the following points For ease of service,the systems are equipped with diagnostic before performing the test: code display LEDs on the indoor and outdoor units. The a. Indoor and outdoor units are properly installed. outdoor diagnostic display has two LEDs (Red and Green) b.

Power voltage is the correct voltage for the air conditioner Test run Instructions 1. Open both the liquid and gas service valves. 2. Turn on the main power switch and allow the unit to warm up. 3. Set the air conditioner to COOL mode. 4. For the Indoor Unit a. Double-check to see if the room temperature is being registered correctly. b. Check to see that the drainage system is unimpeded and draining smoothly. c. Ensure there is no vibration or abnormal noise during operation. 5. For the Outdoor Unit a. Check to see if the refrigeration system is leaking. b. Make sure there is no vibration or abnormal noise during operation. c. Ensure the wind, noise, and water generated by the unit do not disturb your neighbors or pose a safety hazard. 6. Drainage Test a. Ensure the drainpipe flows smoothly. New buildings should perform this test before finishing the ceiling. b. Turn on the main power switch and run the air conditioner in COOL mode. c. Check to see that the water is discharged. It may take up to one minute before the unit begins to drain depending on the drainpipe. d. Make sure that there are no leaks in any of the piping. e. Stop the air conditioner. Turn off the main power switch and reinstall the test cover. NOTE If the unit malfunctions or does not operate according to your expectations, please refer to the Troubleshooting section of the Service Manual before calling customer service. 26 EVOX Extreme Heat Heat Pump Appendix Outdoor Unit Diagnostic Guide For ease of service, systems are equipped with diagnostic code display LEDs on the indoor and outdoor units.
