Safety Cautions For the rear left and left piping Hook 47 mm or more 1 Installation plate Hook 140 mm or more 74 mm or more Hook Wall Insert the cushion between the indoor unit and wall, and tilt the indoor unit for better installation work. 7 Mounting screw Do not allow the drain hose to become slack. Cut the piping hole slightly sloped 5 Zeolite-plus filter Z Shield pipe (for extension drain hose) Make sure the drain hose is sloped downward. 6 Plasma pure filter Air filters Y The auxiliary piping can be connected at the left, rear left, rear right, right, bottom right or bottom left as shown below. 2 Wireless remote controller 100 mm or more from wall (C) 80 mm or more only when unobstructed to the front and both sides In principle, leave open 50 mm or more from wall (D) Right Rear right 4 Remote controller holder (Mounting holes on both left and right sides) 200 mm or more (B) (A) Left Bottom left Bottom right Rear left As shown in the figure, position power cord and connecting cable downward, and lead out along piping connection port. 8 Remote controller holder mounting screw 250 mm or more from wall When installing the outdoor unit, leave open in at least two of directions (A), (B), (C) and (D) shown in the right figure. Ensure sufficient space to allow drainage Power cord Extension drain hose (Option: RB-821SW) Insulate the refrigerant pipes separately, not together. 6 mm thick heat resisting polyethylene foam Before installing the wireless remote controller · With the remote controller cover removed, correctly load the supplied batteries while observing their polarity. 2 Wireless remote controller Cover 3 Batteries ­ 72 ­ 10-2.

Installation/Servicing Tools Changes in the product and components In the case of an air conditioner using R410A, in order to prevent any other refrigerant from being charged accidentally, the service port diameter of the outdoor unit control valve (3-way valve) has been changed. (1/2 UNF 20 threads per inch) · In order to increase the pressure resisting strength of the refrigerant piping flare processing diameter and size of opposite side of flare nuts has been changed. (for copper pipes with nominal dimensions 1/2 and 5/8) New tools for R410A New tools for R410A Applicable to R22 model Changes As pressure is high, it is impossible to measure by means of conventional gauge. In order to prevent any other refrigerant from being charged, each port diameter has been changed. In order to increase pressure resisting strength, hose materials and port size have been changed (to 1/2 UNF 20 threads per inch). As pressure is high and gasification speed is fast, it is difficult to read the indicated value by means of charging cylinder, as air bubbles occur. Incidentally, a common wrench is used for nominal diameters 1/4 and 3/8. By increasing the clamp bar's receiving hole, strength of spring in the tool has been improved. Gauge manifold × × ¡ Charge hose Electronic balance for refrigerant charging Torque wrench (nominal diam. 1/2, 5/8) × ¡ -- -- Flare tool (clutch type) Gauge for projection adjustment Used when flare is made by using conventional flare tool. It is necessary to use an adapter to prevent vacuum pump oil from flowing back to the charge hose. The charge hose connecting part has two ports-one for conventional refrigerant (7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes with R410A a sludge may occur and damage the equipment. Vacuum pump adapter ¡ Gas leakage detector × Exclusive for HFC refrigerant. · Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R410A) and protector coating in the U. · Also, the "charge port and packing for refrigerant cylinder" require 1/2 UNF 20 threads per inch corresponding to the charge hose's port size. ­ 74 ­ 10-3. Installation Place · A place which provides enough spaces around the indoor unit as shown in the diagram. [. . . ] 4306S709 4306S710 4306S711 43067115 Description P Board Ass'y . C.
