To ensure that the air conditioner operates correctly, do not install the remote control unit in the following places: ● In direct sunlight ● Behind a curtain[...]

16 S4359128 ■ Wired Remote Control Unit (Option) (1) To access the printed circuit board, remove the cover plate of the electrical component box. (2) Attach the remote control connectors securely to the mating connector pins on the printed circuit board. (3) Turn the R.C.U. switch from “WIRELESS” to “WIRED”. (4) Replace the cover plate. D[...]

S4359128 17 5. Address Switches If you are installing one indoor unit or one group of indoor units in the same room, it is necessary for you to assign each unit its own address so that each can be operated by its own remote control unit. You assign the addresses by matching the switch position of each indoor unit with the switch position of its rem[...]

18 S4359128 6. Electrical Wiring 6-1. General Precautions on Wiring (1) Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following the wiring diagram. (2) Provide a power outlet to be used exclusively for each unit, and a power supply disconnect and circuit breaker for overcurrent pro[...]

S4359128 21 7. How to Process Tubing The narrow tubing side is connected by flare nut, and the wide tubing side is connected by brazing. 7-1. Use of the Flaring Method Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper t[...]

22 S4359128 7-4. Precautions during Brazing ● Replace air inside the tube with nitrogen gas to prevent copper oxide film from forming during the brazing process. ● Do not allow the tubing to get too hot during the brazing process. The nitrogen gas inside the tubing may overheat, causing refrigerant system valves to become damaged. Therefore all[...]

S4359128 23 Because capillary tubing is installed in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. Therefore, to prevent heat loss and wet floors due to dripping of condensation water, both tubes must be well insulated with proper insulation material. The thickness of the insulation material should be a min. [...]

24 S4359128 CAUTION 8. Air Purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. Therefore, they must be purged completely. ● pressure in the system rises ● operating current rises ● cooling (or heating) efficiency drops ● moisture in the air may freeze and block capillary tubing ● water[...]
