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. ­ 54 ­ 10-3. Installation Place · A place which provides enough spaces around the indoor unit as shown in the diagram. · A place where there are no obstacle near the air inlet and outlet. · A place which allows easy installation of the piping to the outdoor unit. · The indoor unit shall be installed so that the top of the indoor unit is positioned at least 2 m in height. [. . . ] 3) Remove the hooking claws by pushing minus screwdriver according to the arrow mark in the right figure, and remove the fan guard. Minus screwdriver Hooking claw 2. Attachment 1) Insert claws of the fan guard in the holes of the front cabinet. Push the hooking claws (9 positions) by hands and fix the claws. All the attaching works have completed. Check that all the hooking claws are fixed to the specified positions. ­ 101 ­ No. 11 Part name Procedure Remarks TE sensor (Outdoor heat exchanging temperature sensor) · Attachment With the leads pointing downward and the sensor leads pointing in the direction shown in the figure, install the sensor onto the straight pipe part of the condenser output pipe.
