Features 6RWU0-03A 5.
6RWU0-03A Features Washable Filters The Unit uses two filters on the indoor side which can be slid easily. These filters can be taken out without removing the Front Grille and then cleaned by washing or brushing. The filters should be checked and cleaned every two(2) weeks or as necessary to maintain the optimal performance of the air conditioner depending upon the region and purpose of application.
6RWU0-03A Features Electric Heater Electric heaters are used in cold regions when instant heating is required in the room. In such cases, electric heaters are preferred over heat pump models which sometime require long time to achieve the desired heating effect. Fig : Coil Heater Electric Heater are of two types – Coil Heater and PTC Heater Fig : PTC Heater Deice Control When the unit starts operating in the heating mode, then, to protect the outdoor unit pipe from freezing, “deice” control is used.
6RWU0-03A Features Infinite Impulse response (IIR) The IIR function senses the temperature several times per second and make micro adjustments accordingly. Compressor Restart Delay This feature extends the overall life of the compressor by preventing the short cycling of the air-conditioner. When the compressor restarts, LG PTAC is designed to give it a minimum of three minutes to have a time of equalizing the refrigerant pressures for optimizing the cycle.
Features 6RWU0-03A Outdoor Air Temperature switchover This feature changes the operating mode of the unit from the heat pump mode to total resistance heat. Temperature limits The unit is programmed to provide both heating and cooling temperature limits by dip switches on the control panel. The limits are from 50˚ F to 90˚ F. These temperature limits help to prevent overheating and overcooling thereby reducing the energy costs.

POWER • To turn the air conditioner ON, push this button. To turn the air conditioner OFF, push the button again.
6RWU0-03A Control Device Additional Controls Additional controls can be seen after removing the front grille and the option cover of the control box. To remove the front grille, pull out the bottom at both the sides and then lift up the grille as shown in the figure on the right. And to install the front grille back to itʼs original position, place the tabs over the top of the unit and push the bottom of the front grille until the clips snap into place.
Control Device 6RWU0-03A • Remote/Local Control When remote/local switch #1 is on, it allow the unit to operate by the Remote Wall Thermostat. The unit control by knobs are not available. • Energy Saver The energy saver switch #2 is on. This switch is set at cycle fan to provide continuous fan operation in cool or heat modes. When the switch is off the continuous fan allows continuous circulation of room air and make the more balanced temperature of the room.
6RWU0-03A Control Device Remote Wall Thermostat When the wires are connected, the unit will be controlled by a remote wall thermostat. The thermostat connections supply the 24 Volt AC. When you install the digital/electronic thermostat, you must set it to 24 Volt AC. See the installation instruction in this manual for the Remote Wall Thermostat.
