1.2 FEATURES AND BENEFITS

The PTAC has many features, some of which are different than those found on conventional PTAC units. The servicer must be familiar with these features in order to properly service the unit.

• IIR (Infinite Impulse Response) The IIR function senses the temperature several times per second and makes micro-adjustments several times per

• Compressor Restart Delay

This feature extends the overall life of compressor by preventing the short-cycling of the air-conditioner. When the compressor restarts, LG PTAC is designed to give a minimum of three minutes to have a time of equalizing the refrigerant pressures for optimizing cycling.

• Fan-Only Setting - High/Low

The fan can run at HIGH or LOW speed without COOLING or HEATING to provide air circulation and ventilation.

• Indoor Fan Speed Selections - High/Low

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

• Two Fan motors

The unit has two fan motors to provide quiet operation and maximum efficiency.

• Indoor Filters

The unit uses two indoor filters which slide in and cut easily. The filters may be cleaned by washing and brushing without removing the front grille.

• Rotary Compressor

The unit uses a rotary compressor for quiet, reliable operation and long life.

• 2 Position Discharge Grille

The discharge grille can provide air flows upward at an angle of 40 off vertical or 15 degree 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 falls to less than 40° F the unit activates the fan motor and either the electric resistance heater or the hydronic heater to prevent pipes or fixtures from freezing. This also overrides front desk control of the unit mounted or 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. For additional information, refer to the unit operation section.

• Compressor Overload Protection

This feature prevents the damage of the compressor by sensing the indoor tube temperature in heating. If the indoor temperature is over 130˚ F, the outdoor fan will be switched off and back on when the temperature drops below 120˚ F.

• Outdoor Air Temperature Switchover

This will effectively change the unit from heat pump mode to total electric resistance heat.

• Temperature limits

The unit is programmed to provide both heating and cooling temperature limits by dip switches on control panel from 54˚ F to 86˚ F. Temperature limits help to prevent overheating and overcooling and reduce energy costs.

• Condensate Drain Valve

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

• Quick Heater Recovery

The unit is designed to operate the electric heater to warm the room to the temperature set point as soon as heat pump cycle is on in heating. This feature has an advantage of reducing the time to reach the set point and improving the temperature increase for better comfort.

• Reverse Cycle Defrosting - (PTHDs only)

The unit will activate the reverse cycle defrost when the outdoor coil temperature has remained at a cold temperature to form the ice on the coil.This ice will reduce airflow though the coil and will also reduce the efficiency of unit. The LG PTHP will employ an active reverse cycle defrost function to melt the ice off the outdoor coil for insuring room comfort conditions and savings from extended operation.

• High Temperature Heat Pump Operation Protection

The compressor will be switched off to prevent damage when the heat pump is operated in high outdoor temperatures.

• Remote Thermostat Control

Each unit is built to be operated from any standard 4 or 5 wire remote-mounted thermostat, if desired. The unit has a built-in low voltage power source which can accommodate a large variety of thermostat choices-manual, auto changeover, or programmable. A remote thermostat can also be added to any installed unit.

• Zone Sensor

Occupants enjoy ultimate comfort with consistent climate control. Attach an optional, inexpensive remote Zone Sensor to exactly match the functions of the PTAC without disabling any features.

TEMPERATURE CONTROL

Set the Thermostat control to the desired temperature mark 5 (the mid-point is a good starting position). If the room temperature is not satisfactory after a reasonable time, adjust the control to a cooler or warmer setting, as appropriate.

OPERATION MODE SELECTOR

OFF Turns air conditioner off. LOW FAN Low speed fan operation without cooling. HIGH FAN High speed fan operation without cooling. LOW COOL Cooling with the low speed fan operation. HIGH COOL Cooling with the high speed fan operation. LOW HEAT Heating with the low speed fan operation. HIGH HEAT Heating with the high speed fan operation.

• VENTILATION

The ventilation lever is located to the lower left side of the unit. The ventilation lever must be in the CLOSE position in order to maintain the best cooling conditions. When fresh air is necessary in the room, set the ventilation lever to the OPEN position. The damper is opened and outdoor air is drawn into the room. This will reduce the cooling or heating efficiency.

When the air conditioner has performed a cooling or heating operation and is turned off or set to the fan position, wait at least 3 minutes before resetting to the cooling operation.

A slight heat odor may come from the unit when first switching to HEAT after the cooling season is over. This odor, caused by fine dust particles on the heater, will disappear quickly. This is harmless.

— Replacement of the refrigeration cycle.

1. When replacing the refrigeration cycle, be sure to discharge the refrigerant system using a refrigerant recovery system. If there is no valve to attach the recovery system, install one (such as a WATCO A-1) before venting the refrigerant. Leave the valve in place after servicing the system.

2. After discharging the unit completely, remove the desired component, and unbraze the pinch-off tubes.

3. Solder service valves into the pinch-off tube ports, leaving the valves open.

4. Solder the pinch-off tubes with service valves.

5. Evacuate as follows.

1) Connect the vacuum pump, as illustrated

Figure 17 A.

2) Start the vacuum pump, slowly open manifold

valves A and B with two full turns counterclockwise and leave the valves closed. The vacuum pump is now pulling through valves A and B up to valve C by means of the manifold

and entire system.

3) Operate the vacuum pump for 20 to 30 minutes,

until 600 microns of vacuum are obtained. Close valves A and B, and observe the vacuum gauge for a few minutes. A rise in pressure would indicate a possible leak or moisture remaining in the system. With valves A and B closed, stop

the vacuum pump.

Remove the hose from the vacuum pump and place it on the charging cylinder. See Figure 16 B. Open valve C. Discharge the line at the manifold connection.

5) The system is now ready for final charging.

6. Recharge as follows :

1) Refrigeration cycle systems are charged from the high-side. If the total charge cannot be put in the high-side, the balance will be put in the suction line through the access valve which you installed as the system was opened.

Connect the charging cylinder as shown in Figure 17B. With valve C open, discharge the hose at the manifold connection.

3) Open valve A and allow the proper charge to enter the system. Valve B is still closed.

4) If more charge is required, the high-side will not take it. Close valve A.

5) With the unit running, open valve B and add the balance of the charge.

a. Do not add the liquid refrigerant to the low-

side.

b. Watch the low-side gauge; allow pressure to

rise to 30 lbs. c. Turn off valve B and allow pressure to drop. d. Repeat steps B and C until the balance of the

charge is in the system.

6) When satisfied the unit is operating correctly, use the pinch-off tool with the unit still running and clamp on to the pinch-off tube. Using a tube cutter, cut the pinch-off tube about 2 inches from the pinch-off tool. Use sil-fos solder and solder pinch-off tube closed. Turn off the unit, allow it to set for a while, and then test the leakage of the pinch-off connection.

NOTES

If high vacuum equipment is used, just crack valves A and B for a few minutes, then open slowly with the two full turns counterclockwise. This will keep oil from foaming and being drawn into the vacuum pump.

3. INSTALLATION

3.1 HOW TO INSTALL THE UNIT

For existing sleeve, you should measure the wall sleeve

dimensions. Install the new air conditioner according to these installation instructions to achieve the best performence. All wall sleeves used to mount the new air conditioner must be in good structural condition and have a rear grille that securely attaches to the sleeve or the flange of the sleeve to secure the new air conditioner.

• To avoid vibration and noise, make sure the unit is installed securely and firmly.

When installing the sleeve, make certain there is nothing within 20" of the back that would interfere with heat radiation and exhaust air flow.

1) Take out the insulation strip from the upper packing.

2) Attach the insulation strip onto the rear upper side of the

wall sleeve.

3) To improve unit energy efficiency, it is recommended the

change of outside grille for an unit protection and an addition of a plastic rear grille. (This is optional.)

4) Insulation strip prevents the exhaust air from re-entering

from either side of condenser space which may decrease the cooling efficiency of condenser.

3.2 WALL SLEEVE INSTALLATION

3.2.1 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.

Regardless of the installation, there are several things to consider when selecting a location for installing the unit. For instance, drapery location could interfere with air discharge, and placement of furniture may have an impact on the performance of the unit. The following information is intended to minimize installation problems and assure you of trouble-free installation.

Refer to page 24 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. See page 40 for requirements for custom louver sections.

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

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, locating the wall case must be done correctly.

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.

Page 23

—23—

3.2.2

PREPARATION OF THE FRONT GRILLE

Carefully remove shipping tape from the front grille.

Brick, Frame, Stucco and Shingle Construction

For new construction, the opening for the wall case should be framed and the wall case 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

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 23.

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.

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 19. 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 locate 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.

Condensate Disposal Pump Kit Installation

Part No: AYSB3101

Description

The internal condensate pump serves as a means for disposing of condensate generated during heat pump operation by transferring it to the indoor coil. The warm coil surface and the warm room air help in evaporation of the condensate while adding humidity to the room. As with any equipment of this type, the addition of this kit will decrease the effective heating capacity of the unit. This kit is not intended for use in seacoast or corrosive environments.

NOTE:

Under extreme high humidity conditions, the internal condensate pump may not be able to dispose of all the condensate produced, and condensate would then drip from the outside of the wall sleeve. If this condensation is unacceptable, then a drain system (including factory approved drain kit for the wall sleeve) should be installed.

Outdoor Drain Kit Installation

Before installing the wall sleeve louvered condenser grille, it must be determined if the optional outdoor wall sleeve drain kit is to be installed. The drain kit will allow the condensate from the outdoor and indoor coils to be routed to a suitable area. The drain kit can be installed so the condensate can be drained from the right or left hand side of the wall sleeve. See Figure 39. See local codes for proper condensate disposal.

To install the outdoor drain components proceed as follows:

1. Remove the rear enclosure panel and the sleeve stiffener. These items may be removed from the inside of the building.

2. The drain fitting can be installed on the left or right hand side of the sleeve. (Illustration will be for a right hand installation.) Insert the drain fitting in the opening of gasket A and hole of plate B. Secure this assembly to the rear of the sleeve with two sheet metal screws into holes G provided in sleeve. See Figures 40 and 41.

3. Locate the other gasket A on the back of blank off plate C and secure the assembly to the left rear of wall sleeve with sheet metal screws provided. See Figure 42 for finished left hand side installation.

If the unit chassis is to be installed right away, install the condenser grille to wall sleeve with hardware provided. See condenser grille installation instructions.

If the unit chassis will not be installed right away, replace the rear enclosure panel in the wall sleeve. This will help protect the inside of the building from weather damage.

If a subbase is used, be sure the right hand subbase cover is removed before the chassis is installed in the sleeve. Slide the chassis into the wall sleeve until the chassis flanges

contact the front edge of sleeve. Secure the chassis to the wall sleeve on each side with screws provided.

Re-install the cabinet front.

Check voltage at outlet. Correct if none. Check voltage to rotary switch. If none, check

power supply cord. Replace cord if circuit is open. Check switch continuity. Refer to wiring diagram

for terminal identification. Replace switch if defective.

Connect wire. Refer to wiring diagram for terminal identification. Repair or replace loose terminal.

Test capacitor. Replace if not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged.

Fan blade hitting shroud or cross flow fan hitting scroll. Realign assembly.

Units using slinger ring condenser fans must have 1/4to 5/16inch clearance to the base. If it is hitting the base, shim up the bottom of the fan motor with mounting screw(s).

Check fan motor bearings; if motor shaft will not rotate, replace the motor.

Check voltage. See limits on this page. If not within limits, call an electrician.

Test capacitor. Check bearings. Does the fan blade rotate freely? If not, replace fan motor.

Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor.

Check grommets; if worn or missing, replace them. If cracked, out of balance, or partially missing,

replace it. If cracked, out of balance, or partially missing,

replace it. Tighten it. If knocking sounds continue when running or

loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor.

COMPLAINT CAUSE

REMEDY

Check the voltage. See the limits on the preceding page. If not within limits, call an electrician.

Check overload, if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool, and retest.)

If not running, determine the cause. Replace if required.

Remove the cabinet. inspect the interior surface of the condenser; if restricted, clean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before reassembling.

If condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to cycle. Straighten the fins or replace the coil. Test capacitor. Check the terminals. If loose, repair or replace. Check the system for restriction. If restricted, clean of replace. Close if open. Determine if the unit is properly sized for the area to be cooled. Check the set screw or clamp. If loose or missing, correct. If the blower or fan is hitting air guide, rearrange the air handling parts. Carefully rearrange tubing not to contact, compressor, shroud, and barrier.
