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.

• LED Diagnostics

All units have this feature indicating the problem when the unit is not operating properly with easy-to-read diagnostics. For
example, 1 blink every 2 seconds indicates compressor failure.

• 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 50˚ F to
90˚ 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.

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 16 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.

4)

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.

2)

Connect the charging cylinder as shown in Figure
16B.
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.

3.1 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.

Insulation strip must be
attached to prevent the re­circulation of exhaust air to
inward side from the either
side of condenser space. The
insulation strip is provided
with the box.
Refer to the diagram below.

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.

Condensate Disposal Pump Kit
Installation

Part No: AYSB2101

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.

Receiving

Upon receipt of the product, inspect the shipping carton for
signs of visible damage. Report any damage or shortage to
the carrier and note it on the delivery receipt. Unit must be

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 36. 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 37 and 38.

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 39 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.

Indoor Drain Kit Installation

The internal drain is installed on the bottom of the wall sleeve
when it is required to drain the condensate into a drain
system inside of the building.
The components of the wall sleeve drain kit are shown in
Detail A. Use components C (2), D, E, mounting screws (6)
and the Outdoor drain fitting.

1. The components D, E, and drain fitting of the kit are
mounted on the bottom of the wall sleeve prior to the
installation of the sleeve. It may be located in a feasible
area on the bottom of the sleeve which is inside of the
room except when a subbase is used. When a subbase is
installed, the drain may be a minimum of 3 1/2 " from the
front flange of the wall sleeve. The minimum clearance
should provide adequate clearance for the subbase, see
Figures 40 and 41.

2. Cut out the template in the lower right hand corner of these
instructions to locate the field drilled holes. (Two to mount
the plate and one for the Outdoor drain fitting). See Detail
A on how the components have to be installed after the
holes are drilled in the bottom of the wall sleeve. If the
drain fitting is not connected to an indoor drainage system
immediately after the wall sleeve is installed, it must be
plugged with a cork to prevent indoor water damage in
case it rains.

An indoor tube or hose (furnished by others) must be installed
on the drain fitting and interconnected to the drain system
inside of the building.

Install the two blank-off plates C and gaskets A on the
outdoor portion of the wall sleeve as shown in Figure 40.
These components may be installed after the sleeve is
secured in the wall opening just prior to the installation of the
condenser grille and chassis.

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.
