Especially in windy areas, install the unit to prevent the admission of wind. Installation in the following places may result in trouble. · A saline-place such as the coast. · A place where high-frequency waves are likely to be generated, such as from audio equipment, welders, and medical equipment. Strong wind Fig. Draining the Water · Holes are provided on the base plate of the outdoor unit to ensure that the defrost water produced during heating operations is drained off efficiently. If a centralized drain is required when installing the unit on a balcony or wall, follow the steps below to drain off the water. Proceed with water-proofing by installing the water-proof rubber caps in the 2 elongated holes on the base plate of the outdoor unit. [How to install the water-proof rubber caps] 1) Place four fingers into each cap, and insert the caps into the water drain holes by pushing them into place from the underside of the base plate. 2) Press down on the outer circumferences of the caps to ensure that they have been inserted tightly. (Water leaks may result if the caps have not been inserted properly, if their outer circumferences lift up or the caps catch on or wedge against something. ) 10-4-3. [. . . ] When there is the heating part near the electric parts box, a fire may generate. Be sure to set the heating part on the outdoor unit base plate at the fan room side or near it. (within 20cm from the outdoor unit base plate) * Be careful that the cord heater does not hit the fan. Fix the cord heater without any loosening or sag. [. . . ]
