For general public use Power supply cord of outdoor unit shall be 1. 5 mm ² (H07RN-F or 60245IEC66) polychloroprene sheathed flexible cord. · · · · Read this "SAFETY PRECAUTIONS" carefully before servicing. [. . . ] In order to prevent any other refrigerant from being charged, the port diameters have been changed. In order to increase pressure resisting strength, hose materials and port sizes have been changed (to 1/2 UNF 20 threads per inch). As working 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. Charge hose Electronic balance for refrigerant charging Torque wrench (nominal dia. 1/2, 5/8) Flare tool (clutch type) By increasing the clamp bar's receiving hole size, strength of spring in the tool has been improved. 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 into the charge hose. The charge hose connecting part has two ports -- one is for conventional refrigerant (7/16 UNF 20 threads per inch) and the other is for R410A. If the vacuum pump oil (mineral) mixes with R410A, a sludge may occur and damage the equipment. Exclusive for HFC refrigerant. Vacuum pump adapter 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" requires 1/2 UNF 20 threads per inch corresponding to the charge hose's port size. 59 High Wall, Heat Pump Type Service Manual 9-3. Installation Location · A place which provides enough space around the indoor unit as shown in the diagram. · Check local electrical regulations for any specific wiring instructions or limitations. Failure to securely install the unit may result in personal injury and/or property damage if the unit falls. · In case of block, brick, concrete or similar type walls, drill 5 mm dia. NOTE Install the installation plate using between 4 to 6 mounting screws, making sure all four corners are secure. Terminal cover Screw Terminal block Earth wire Screw Connecting cable 9-3-3. Electrical Work · 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: H07RN-F or 60245IEC66 (1. 0 mm2) · Make sure the wire length is sufficient before performing wiring work. Earth wire(loop) Cord clamp Terminal block Earth screw 9-3-4. Wiring Connection Connecting cable (Wiring the connecting cable can be carried out without removing the front panel. ) 1) Pull the handles on the bottom of the right and left sides, and open the moving panel until it is horizontal. 3) Insert the connecting cable (or as according to local regulations/codes) into the pipe hole on the wall. 4) Pull the connecting cable through the cable slot on the rear panel so that it protrudes about 15 cm out of the front. Connecting cable about 15 cm 110 mm 10 mm Earth line 10 mm 50 mm 61 High Wall, Heat Pump Type Service Manual NOTE · Connecting cable (Indoor unit/outdoor unit) · Wire type: H07RN-F or 60245IEC66 (1. 0 mm2) 4) Attach the drain cap Insert hexagonal wrench (4 mm). 9-3-5. Piping and Drain Hose Installation Piping and drain hose forming Since condensation results in machine trouble, make sure to insulate both the connecting pipes separately. (Use polyethylene foam as insulating material. ) Rear right Rear left Bottom left Left Bottom right Right Die-cutting front panel slit Changing drain hose 5) Firmly insert drain cap. No gap Do not apply lubricating oil (refrigerant machine oil) when inserting the drain cap. Insert a hexagon wrench (4 mm) Piping preparation 6) Attach the drain hose Insert the drain hose firmly until the connector contacts the insulation, then secure it in place using the original screw. [. . . ] Heater for Antifreeze Detachment 1) Perform steps in 11-3-8. Compressor Assembly (except for step 6). (ST1TØ4 × 10L 1pc. ) 3) Remove the 12 cord clamps fixing the heater to the bottom plate, and detach the heater. 4) Attach a new heater to the bottom plate using the cord retainer and cord clamps supplied with the heater assembly (for service). (Part number: 375-57-729) Bottom plate heater Cord clamp (12 locations) Cord retainer 11-3-10. Fan Guard Detachment 1) Perform the step of detachment in 11-3-2. [. . . ]
