[. . . ] 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). When purchasing a charge hose, be sure to confirm the port size. 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. The size of opposite sides of flare nuts have been increased. 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. The supply voltage must be the same as the rated voltage of the air conditioner. Prepare a power source for the exclusive use of the air conditioner. NOTE : · Wire type : More than 1. 5 mm² H07RN-F or 60245IEC66. CAUTION CAUTION When installing the installation plate with mounting screw, do not use the anchor bolt hole. Otherwise the unit may fall down and result in personal injury and property damage. Anchor bolt Projection 15 mm or less This appliance can be connected to a main circuit breaker in either of the following two ways. Connection to fixed wiring: A switch or circuit breaker which disconnects all poles and has a contact separation of at least 3 mm must be incorporated in the fixed wiring. An approved circuit breaker or switch must be used. Connection with power supply plug: Attach power supply plug with power cord and plug it into wall outlet. An approved power supply cord and plug must be used. Fig. 10-3-4 NOTE : · Perform wiring work being sure the wire length is long enough. 5 mm dia. Wiring Connection 7 Mounting screw Ø4 × 25 l How to connect the connecting cable Wiring the connecting cable can be carried out without removing the front panel. Open the air inlet grille upward and pull it toward you. Remove the terminal cover and cord clamp. [. . . ] Perform work on a corrugated cardboard, cloth, etc. 3) Remove the hooking claws by pushing minus screwdriver according to the arrow mark in the right figure, and remove the fan guard. 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. Minus screwdriver Hooking claw Check that all the hooking claws are fixed to the specified positions. ­ 107 ­ FILE NO. [. . . ]
