Others Name Owner's manual Installation manual ­ 49 ­ FILE NO. 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 Gauge manifold 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). When purchasing a charge hose, be sure to confirm the port size. As pressure is hight 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. -- Charge hose Electronic balance for refrigerant charging Torque wrench (nominal diam. 1/2, 5/8) Flare tool (clutch type) Gauge for projection adjustment Vacuum pump adapter 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. Exclusive for HFC refrigerant. Gas leakage detector · Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R410A) and protector coating in the U. S's ARI specified rose color (ARI color code: PMS 507). · 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. ­ 50 ­ FILE NO. [. . . ] Attachment 1) Insert the claws of the fan guard in the hole of the front cabinet. Push the hooking claws (8 positions) by your hand and fix the claws. Requirement: This completes all the attaching work. Check that all the hooking claws are fixed to the specified positions. [. . . ]
