It is suggested to run this feature once every 3 months. 4 Page 19 Owner's Manual Owner's Manual Operating Instructions 4 An Important Note Regarding Operating Temperatures The system is designed to run within a certain range of temperatures, which are listed below. There are built-in protections with the system that may stop the appliance when the ambient temperature goes outside of these ranges. Inverter Air Conditioner Temperature Operating Mode COOLING Mode HEATING Mode DRYING Mode Current Room Temperature 63°F - 89°F 32°F - 86°F 63°F - 89°F Ambient Outdoor Temperature 5°F - 127°F -13°F - 86°F 59°F - 127°F NOTE After stopping and restarting the air conditioner, or after the mode is changed during operation, the system does not restart immediately, and will come on when three minutes have elapsed (as a protection for the compressor). Full system-rated capacity and efficiency is obtained at the standard rating conditions as developed by the testing and rating agencies. Deviations from the rating conditions, especially the atmospheric conditions, will be compensated by the variable speed compressor, within certain limitations. Heat pump systems function by exchanging energy, in the form of heat, between the indoor air and the outdoor ambient air (atmospheric). The system's net cooling or heating capacities and efficiencies change by atmospheric conditions, as well as the indoor air conditions (such as temperatures and humidity levels). Capacity of the system required for a specific area or application must be determined professionally using detailed calculations, which are based on several internal and external factors. To further optimize the performance of your unit, be sure to do the following: · Keep doors and windows closed. · Limit energy usage by using TIMER ON and TIMER OFF functions. · Do not block air inlets or outlets. · Regularly inspect and clean air filters. Page 20 Maintenance of the Air Conditioner 5 Maintenance Instructions Periodic Maintenance Is Essential for The System! Maintaining the air conditioner will ensure that is stays efficient.

Page 25 Indoor Unit Installation 6 Indoor Unit Installation Instructions Preparing the Refrigerant Piping of the Indoor Unit The piping "pigtails" pre-attached to the indoor unit can be run in 3 different ways as shown in the illustration. Decide which type of configuration is most suitable before continuing. By default, it is routed for a left side exit as shown in #1. This method can either use the left side knockout for a side exit, or a wall hole can be drilled on the left side of the unit's rear. Routing it straight through the back of the system (#2) will facilitate the connections to the copper pipe extensions to be made outside. This is recommended to simplify the process. #3 is a right-side exit, but is not recommended as it involves a 180° bend of the piping, which increases the risk of kinking or collapsing the lines dramatically. Bend slowly and cautiously. If a side-exit is chosen, there are knock-out panels on either side of the unit that can be cut out along the groove to provide a notch for the pipe to exit from. Use a cutter to do this. For the method chosen, run the piping in the direction of the wall hole. Bind the copper pipes, drain line, and power cables together with tape, with the drain pipe at the bottom so that water can flow freely. Ensure that the bundle is exiting at a continuous downward pitch. 3 21 Downward Inclination CAUTION · Do not remove the cap from the pipe until it is time to connect it, to avoid dampness or dirt from entering. · If the pipe is bent/pulled too often, it will become stiff. Do not bend the pipe more than three times at one point. Be extremely careful not to kink any piping. · When extending the coiled copper pipes, straighten them by unwinding gently, as shown in the picture. Page 26 NO YES Unwind the coil gently rather than pulling at ends 6 Indoor Unit Installation Instructions Indoor Unit Installation Connecting the Drain Hose By default, the drain hose is attached to the left-hand side of unit ("left" when facing the back of the unit). However, it can also be attached to the right-hand side. 1. To ensure proper drainage, attach the drain hose on the same side that your refrigerant piping exits the unit. 2. Attach any drain hose extensions (sold separately) to the end of drain hose. 3. Wrap the connection point firmly with Teflon tape to create a good seal, and to prevent leaks. 4. For the portion of the drain hose that will remain indoors, wrap it with foam pipe insulation to prevent condensation. 5. Remove the air filter and pour a small amount of water into the drain pan to make sure that water flows from the unit smoothly. NOTE ON DRAIN HOSE PLACEMENT Make sure to arrange the drain hose according to the illustrations. DO NOT kink the drain hose. DO NOT create a water trap (siphon). DO NOT put the end of the drain hose in water or in a container that will collect water. DUAL DRAIN HOLE LOCATIONS EXIST The indoor unit has 2 drain connections on left and right sides. Either one can be utilized. One side will have a hose connected, while the other is plugged.
