Securely fit the installation plate onto the wall by screws with the upper and lower catches, that hold the indoor unit, facing out. To mount the installation plate on a concrete wall use anchor bolts. Drill the anchor bolt holes previous page. Install the installation plate horizontally and level. 10-3-3. 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. This appliance can be connected to a main circuit breaker in either of the following two ways. Changing drain hose For left connection, left-bottom connection and rear-left connection's piping, it is necessary to relocate the drain hose and drain cap. Stripping length of the connecting cable Fig. 10-3-6 110mm 10mm How to remove the drain cap Earth line Clip drain cap with needle-nose pliers, and pull out. 10mm 50mm Fig. 10-3-7 NOTE : WIRE TYPE : More than 1. 0mm². (H07 RN-F or 60245 IEC 66). How to remove the drain hose The drain hose is secured in place by a screw. Remove the screw securing the drain hose, then pull out the drain hose. Heat insulator Drain hose Fig. 10-3-10 ­ 57 ­ Piping preparation How to attach the drain cap 1. Insert hexagonal wrench (4 mm). In case of bottom right or bottom left piping · After making slits on the front panel with a knife or similar tool, cut them out with a pair of nippers or an equivalent tool. Slit 4 mm Fig. Firmly insert drain cap. Left-hand connection with piping Bend the connecting pipes so that they are positioned within 43 mm above the wall surface. If the connecting pipes are positioned more than 43 mm above the wall surface, the indoor unit may be unstable. When bending the connecting pipe, make sure to use a spring bender to avoid crushing the pipe. No gap Do not apply lubricating oil (refrigerant machine oil) when inserting the drain cap. If applied, deterioration and drain leakage of the drain plug may occur. Insert a hexagon wrench (Ø4mm) Refer to the table below for the bending radius of each connection pipe. Outer diameter 6. 35 mm Bending radius 30 mm 50 mm Fig. [. . . ] 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. Detail C for RAS-18SAV-E 12 Detail C for RAS-22SAV-E TS sensor (Suction pipe temperature sensor) · Attachment With its leads pointing downward, point the sensor in the direction of the packed valve, and install it onto the straight pipe part of the suction pipe. TD sensor (Discharge pipe temperature sensor) · Attachment With its leads pointed downward, install the sensor onto the vertical straight pipe part of the discharge pipe. TO sensor (Outside air temperature sensor) · Attachment Insert the outdoor air temperature sensor into the holder, and install the holder onto the heat exchanger. 13 14 Detail A TS sensor Detail B TD sensor Arrow D TO sensor CAUTION During the installation work (and on its completion), take care not to damage the coverings of the sensor leads on the edges of the metal plates or other parts. It is dangerous for these coverings to be damaged since damage may cause electric shocks and/or a fire. [. . . ]
