[. . . ] 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. ­ 55 ­ FILE NO. 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 2m in height. · Also, avoid putting anything on the top of the indoor unit. 10-3-2. Drilling a Hole and Mounting Installation Plate Drilling a hole When install the refrigerant pipes from the rear. Pipe hole 65 mm CAUTION 100 mm · Direct sunlight on the indoor unit wireless receiver should be avoided. · The microprocessor in the indoor unit should not be too close to r-f sources. After determining the pipe hole position on the installation plate ( ð ) drill the pipe hole (Ø65 mm) at a slight downward slant to the outdoor side. Remote controller · Should be placed where there are no obstacles, such as curtains, that may block the signal. · Do not install the remote controller in a place exposed to direct sunlight or close to a heating source, such as a stove. · Keep the remote controller at least 1 m away from the nearest TV set or stereo equipment. (This is necessary to prevent image disturbances or noise interference. ) · The location of the remote controller should be determined as shown below. NOTE : · When drilling into a wall that contains a metal lath, wire lath or metal plate, be sure to use a pipe hole brim ring sold separately.
