Check that the gas and liquid side service valves are fully open. Measure the temperature of the intake and discharge of air. Ensure the difference between the intake temperature and the discharge is more than 46. 4°F(8°C) (Cooling) or (Heating). Intake temperature Prepare remote control 1. Remove the battery cover by pulling it according to the arrow direction. Insert new batteries making sure that the (+) and (­) of battery are installed correctly. Reattach the cover by pushing it back into position. NOTE: · Use 2 AAA(1. 5volt) batteries. · Remove the batteries from the remote control if the system is not going to be used for a long time.
