[. . . ] Fix the pipings onto the wall by saddle or equivalent. Seal a small opening around the pipings with gum type sealer. Drain Pipe Work I Drain Piping of Ceiling Cassette · Drain piping must have down-slope (1/50 to 1/100): be sure not to provide up-and-down slope to prevent reversal flow. · During drain piping connection, be careful not to exert extra force on the drain port on the indoor unit. · The outside diameter of the drain connection on the indoor unit is 32mm. Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings · Be sure to install heat insulation on the drain piping. Heat insulation material: Polyethylene foam with thickness more than 8 mm. I Install the drain raising pipes at a right angle to the indoor unit and no more than 300mm from the unit. Drain raising pipe Clamp metal(attached) Drain hose(attached) Pipe clamp Indoor unit Upward routing not allowed Maintenance drain port 300mm or less 1 -1. 5m 700 or less Drain test The air conditioner uses a drain pump to drain water. Use the following procedure to test the drain pump operation: Feed water Main drain pipe Drain port Flexible drain hose (accessory) Drain Pump Glue the joint Drain hose connection Use the clip (accessory) · Connect the main drain pipe to the exterior and leave it provisionally until the test comes to an end. · Feed water to the flexible drain hose and check the piping for leakage. · Be sure to check the drain pump for normal operating and noise when electrical wiring is complete. 6) Be sure that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the name plate. 7) Confirm that the cable thickness is as specified in the power sources specification. (Particularly note the relation between cable length and thickness. ) 8) Never fail to equip a leakage breaker where it is wet or moist. 9) The following troubles would be caused by voltage drop-down. · Vibration of a magnetic switch, damage on the contact point there of, fuse breaking, disturbance to the normal function of a overload protection device. · Proper starting power is not given to the compressor. HAND OVER Teach the customer the operation and maintenance procedures, using the operation manual (air filter cleaning, temperature control, etc. ). 30 Ceiling Cassette Air Conditioner Installation 9. Optional Operation 1) Two Thermistor System (1) Open the rear cover of the wired remote-controller to set the mode. (2) Select one of three selectable modes as follows. · Position 1: The room themperature is controlled by the thermistor of the wired remote-controller, control the temperature according to the position of wired remote-controller. · Position 2: The room temperature is controlled by the thermistor of the main body. · Position 3: The room temperature is controlled by lower temperature between the temperature of main body and of remote-controller sensor. [. . . ] Connect the vaccum pump to the center hose of the manifold gauge. Connect the service port of the gas side valve to the low side of the gauge. - Confirm that the gauge needle has moved toward-76 cmHg (vacuum of 4 mmHg or less). Close the Low handle of the gauge turn off the vacuum pump, and confirm that the gauge needle does not move(approximately 5 minutes after turning off the vacuum pump). [. . . ]
