NOTE · Hole should be made at a slight downward slant on the outdoor side. OK 50 mm or more NO GOOD Do not form the drain hose into the waved shape. Do not rise the drain hose. 1 Hook here [1] Installation plate Do not put the drain hose end into water. Do not put the drain hose end in the drainage ditch. 2 Fig. Put water in the drain pan and make sure that the water is being drained outside. When connecting extension drain hose, insulate the connection part of extension drain hose with shield pipe. Shield pipe Hook Fig. 10-3-19 · For detaching the indoor unit from the installation plate pull the indoor unit toward you while pushing the bottom up at the specified places. Drain hose Inside the room Extension drain hose Fig. 10-3-22 Push Push CAUTION Push (unhook) Install the drain pipe for proper drainage. Improper drainage can result in water dripping inside the room. This air conditioner has been designed to drain water collected from condensation which forms on the back of the indoor unit, to the drain pan. Therefore, do not locate the power cord and other parts at a high place above the drain guide.

Refrigerant Piping · Piping kit used for the conventional refrigerant cannot be used. Piping connections to the outdoor unit should be arranged in the sequence A, B, C, D, E starting from the bottom. (For each piping connection, the gas pipe is on the bottom and the liquid pipe is on the top. ) 2. When multiple indoor units are to be connected to the outdoor unit, make the ends of the pipes and wires from each indoor unit to ensure that they will be connected to the outdoor unit correctly. (Problems caused by indoor units being connected to the outdoor unit incorrectly are very common in multiple-unit installations. ) 3.

[. . . ] If the cover of the sensor lead wire is damaged, it is dangerous because an electric shock or fire may be caused. NOTE) After replacing of parts, check the sensors are mounted at the specified positions. If there are incorrect mounted positions, control of the product does not operate correctly and a trouble may be caused. Pass TG sensor through the Bundling band upper side of connecting pipe of Td sensor PMV unit (Black) and then bind Case thermo it with lead wire of PMV coil. Reactor lead NOTE) Using the bundling band being on the market, be sure to bind the position which was bound. ­ 139 ­ No. 19 Part name Sensor wiring process (Continued) Procedure Bind TS sensor, TE sensor and TO sensor with the bundling band. Pass TE sensor and TO sensor through upper part of the inverter fixing board and then bind them with the bundling band. Remarks Inverter fixing board NOTE) Using the bundling band being on the market, be sure to bind the position which was bound.
