Items to Check Before the Test Run(1)(2)Turn the remote power switch ON at least 12 hours in advance in order to energize the crankcase heater.Fully open the closed valves on the liquid-tube and gas-tube sides.NOTE2-11. Preparation for Test Run2-11-1. Switching the temperature sensorTemperature sensors are contained in the indoor unit and wireless remote controller.One or the other of the temperature sensors is used for operation.If (body sensor) appears on the LCD display of the wireless remote controller, then the indoor unit bodysensor is used for operation.To switch to the remote controller sensor, open the remote controller cover and press the SENSOR buttononce. The (body sensor) display disappears and the remote control sensor is used for operation.Even if the remote controller sensor is selected, the sensor will be automatically switched to the indoor unitbody sensor if no temperature signal has been received from the remote controller for 10 minutes. Install theremote controller in a position where the signal can be reliably received by the unit.When group control is engaged, be sure to use the body sensor.2-11-2. Using the remote controllerFace the remote controller toward the receiver (on the main unit). (Fig. 2-8)The signal can be received up to a distance of approximately 8 m.Use this distance as a guide.This distance may vary somewhat depending on the battery capacity and other factors.Be sure that there are no objects between the remote controller and the receiver which may block the signal.The unit beeps when a signal is received correctly. (For operation start only, the unit beeps twice.)Do not drop, throw, or wash the remote controller.Do not place the remote controller in locations exposed to direct sunlight or nearby a stove.Fig. 2-8OPERATION TIMER STANDBYReceiver
