Air Flow can be adjusted by changing the direction of the air conditionerʼs louvers to attain the desired level of comfort and convenience. This can also increase the cooling efficiency of the air conditioner.

In order to attain maximum cooling efficiency, adjust the louvers so that they face upwards.

6RWU0-03A

Washable Filters

Features

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.

Low Noise at High Air Volume

New Blowers and Fans which are bigger and stronger than earlier ones operate at low rpmʼs and have higher efficiency.

High Efficiency Compressor

LG Rotary compressors have low noise, low vibration and higher efficiency and reliability.

Energy save mode

This feature employs a programmable logic which enables the unit to minimize power consumption. When the switch is activated in the “on” position, the Indoor fan turns off as soon as the compressor stops running. And in the “off” mode, the indoor fan runs continuously even if the compressor stops running.

Timer

By this feature we can set the operating time of the air conditioner from one(1) hour up to a time of 12 hours. In the “Off” mode, the Air Conditioner stops operating after the set time, while in the “On” mode, the Air Conditioner timer can be set so that the unit starts operating at the desired time.

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.

Electric Heater are of two types – Coil Heater and PTC Heater Fig : Coil Heater

6RWU0-03A

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. By exercising this control, the cycle is reversed into the cooling mode; to deice or defrost the condenser tubes in the outdoor unit.

Air Ventilation

Air ventilation is carried out by means of a ventilation lever from time to time to induct fresh air into the room. For the air conditioner to maintain the best cooling conditions, the lever must be in the closed position. And when the ventilation lever is set in the open position, the damper opens and the room air is exhausted while at the same time fresh air from outside enters the room.

VENT

Energy saving Gold Fin

Heat exchangers are coated with anti-corrosive and Hydrophilic layers. It prevents the corrosion of heat exchanger.

Fins remain new for a long time and the efficiency of the heat exchanger remains constant thereby saving power and maintenance cost.

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.

Fan only setting

When the Fan only setting is made, only the fan on the indoor side operates while the compressor stops operating and the unit ceases to run in the Cooling or the Heating mode.

Indoor Fan speed setting

The Indoor fan can run at HIGH or LOW speed for either COOLING or HEATING operation.

Two Fan motors

The air conditioning unit has two fan motors for providing a quiet operation and maximum efficiency.

LED Diagnostics and Self Diagnostics

LED Diagnostics feature indicates the problem by its easy to read diagnostics, when the unit does not operate properly. For example, one blink every 2 seconds indicate compressor failure.

While Self Diagnostics feature is used in micom models and it indicates the problem by a displaying a set of error codes.

2 position discharge grille

The discharge grille can provide air flow upwards at an angle of 40˚ off vertical or 15˚ off vertical. The angle is changed by removing the front grille and 4 screws that fasten the discharge grille to the front grille and rotating the louvers to an alternate position.

Indoor room freeze protection

When the unit senses the room temperature to be less than 40˚ F, the unit activates the fan motor and either the electric resistance heater or the hydronic heater, to prevent the pipes or fixtures from freezing. This also overrides the front desk control of the unit mounted controls or the wall mounted controls.

Door Switch/Occupancy Sensor

The unit is capable of accommodating a field installed door switch and occupancy sensor to operate the energy management feature by checking whether any people are present inside the room or not. If there are no people inside the room, the energy management feature is in play.

Compressor Overload protection

This feature prevents damage of the compressor by sensing the indoor coil temperature during the heating mode. If the indoor coil temperature is over 130˚ F, the outdoor fan is switched off and it operates again only when the temperature drops below 120 ˚ F.

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.

Condensate Drain Valve

The unit has a condensate drain valve to prevent water from collecting and freezing in the basepan.

Quick Heater Recovery

The unit is designed to operate the electric heater so as to warm the room to the desired temperature set point as soon as the Heat Pump cycle operates. This feature has an advantage of reducing the time to reach the desired temperature for better comfort.

Reverse Cycle Defrosting – (PTHPʼs only)

This feature enables the unit to activate the reverse cycle defrost so as to prevent the formation of ice on the outdoor unit, which is exposed to cold environment. Formation of ice reduces the airflow through the coil and hence the efficiency of the air conditioning unit. The LG PTHP employs an active reverse cycle defrost function to melt the ice off the outdoor coil for ensuring room comfort conditions and savings from extended operation.

High Temperature Heat Pump Operation Protection

When the unit operates at high outdoor temperature conditions during the cooling cycle, this feature switches off the compressor to prevent damage.

Remote Thermostat Control

The PTAC air conditioning unit is designed and built to be operated from any four(4) or five(5) wire remote mounted thermostat if desired. The unit has a builtin low voltage power source which can accommodate any of the thermostat choices – manual, auto changeover or programmable. A remote thermostat can also be added to any unit.

Zone Sensor

The PTAC air conditioning unit can be controlled by means of a Zone Sensor which carries out the same functions as that of a Wall Thermostat. In other words, it is a remote wall thermostat.

Wall Case Installation Data

General

Generally, units are installed 3" to 5" above the floor

(flush to finished floor installation is possible) as near to the center of the room as possible; underneath a window or a glass panel is typical. Normal installation of the wall case allows installation flexibility; from flush with the finished interior wall to a minimum of 1/4" of the wall case extending beyond the finished exterior of the building.

Special consideration must be given to installations where the wall case does not extend a minimum of 1/4" beyond the finished exterior wall.

framing, moving electrical outlets, and other expensive modifications.

For existing construction it is important that carpentry, masonry and electrical work be performed by competent, qualified personnel. Since installations in existing construction may involve removal of building material from the structure, location of the wall case must be precisely done.

Refer to last page for required wall opening dimensions. Minimum recommended interior and exterior case projection for standard wall thicknesses are shown in the drawings in this manual. The case may be installed flush with the finished indoor wall.

Mounting an outdoor grille or louver section to the building face may cause a space between the outdoor coil and the louver section. Air splitters, aligned with the ends of the outdoor coil, must be installed between the outdoor coil inlet and outlet air streams. Gaps between the outdoor coil and the louver section may allow condenser air recirculation and affect the operation of the unit.

The wall case should be level from side to side and from level to 1/4 bubble tilt to the outdoors.

The condensate disposal system in the unit is designed to dissipate the condensate water generated during cooling operation in accordance with ARI standards and actually uses this water for maximum unit efficiency. A level unit will also insure proper performance of the Internal

Condensate Removal (ICR) system optional on heat pump units.

For new construction, early planning with the architect is necessary. Unit location, electrical connection locations, and wall openings of proper dimension are essential to avoid the necessity of rework, fillers,

Preparation of the front grille

Carefully remove shipping tape from the front grille.

The outside edge of the wall case should extend at least

1/4" beyond the outside wall.

This is necessary for proper caulking, to prevent sealing thedrain holes in the rear flange of the wall case, and to facilitate the installation of an accessory drain, if used.

Shipping Tape

The wall case should be level from side to side and from level to 1/4 bubble tilt to the outdoors. The condensate disposal system in the unit is designed to dissipate the condensate water generated during cooling operation in accordance with ARI standards and actually uses this water for maximum unit efficiency. A level unit will also insure proper performance of the Internal Condensate Removal

(ICR) system optional on heat pump units.

Brick, Frame, Stucco and Shingle

Construction

For new construction, the opening for the wall case should be framed and inserted into the opening during construction. Lintels should be used when the building material is heavy and is not self supporting (such as brick). The wall case will fit an opening of six courses of standard brick or five courses of jumbo brick. Wall framing in this type construction is normally on 16" centers and the wall case will fit a framed opening spanning three 16" O.C. 2" x 4" stud spaces.

For existing construction the indoor and outdoor wall will need to be cut out, allowing for clearances of 1/8" on all sides of the wall case. Work should begin on the inside wall.

Cut the correct dimensions and mark (using drill holes) the outside wall from each corner of the inside cutout. Studding that interferes with the opening must be removed and a suitable frame constructed to secure the wall case and provide adequate support for case and chassis.

Preparation of the Wall Case for All Types of

Construction

As shipped, the LG wall sleeve is ready for installation.

Do not remove the stiffener from inside the wall case or the weather closure panel from the outside face of the wall case until the outdoor grille and chassis are ready to be installed.

Installation of Wall Case in Wall Opening

1. Position the wall case into the wall. The room side edge of the wall case should be at least flush with the finished wall for line cord installations and permanent connection installations when no sub-base is used, and should project into the room at least 2-3/8" when a sub-base is used. If the minimum exterior dimensions are not met, refer to page 60.

2. The wall case should be secured to the wall at both sides.

Use a minimum of two screws or other fastening device on each side. See Figure 2 page 60. Mark the wall case on each side 2" from the bottom and 2" from the top at a point where basic wall structure is located. Drill wall case and use fasteners appropriate for wall construction. All holes for fasteners in the side of the wall case must be at least 2" up from the bottom of the wall case.

Never fasten screws or put other holes in the bottom of the wall case.

If the wall opening is greater than the case dimensions, spacers must be used on the sides between the wall case and the wall support structure to prevent distorting the wall case.

3. Caulk or gasket the entire opening on the outside between the wall case and exterior wall surface (4 sides) to provide total water and air seal.

4. Caulk or gasket room-side opening between wall case and interior wall surface (4 sides). Opening beneath or around the wall case can allow outdoor air to leak into the room resulting in increased operating costs and improper room temperature control.

Care should be taken in location of electrical supply entry in relationship to wall sleeve to assure access to receptacle or junction box once unit is installed.
