Convergence of Technological Innovation with Flexibility and Style
Single Zone Wall
Mounted Art Cool
Premier Systems
Choosing an LG Single Zone Wall Mount-
ed Art Cool Premier product provides a
system designer an edge to engineer
a system with individual control, and
design flexibility with advanced controls.
These single-zone systems are avail-
able in a nominal capacities of 3/4 to 2
tons. These are best suited for applica-
tions with zones that require heating or
cooling, such as residential, and small
business office buildings. Single Zone
Wall Mounted Art Cool Premier out-
door and indoor units are available in
208–230V/60Hz/1Ph.
Adaptable and Flexible
Single zone wall mounted split systems
allow cooling or heating for the entire
residence or just a single room without
the need for invasive ductwork. There is
minimal renovation needed.
Long refrigerant piping lengths allow
for extra design flexibility in indoor unit
installation.
These units may be used for a number of
residential or commercial environments
such as:
• Older homes
• New home construction
• Office buildings
• Restaurants
• Hospitals / Medical facilities
• Schools
• Nursing homes
• Retail establishments
• House of worship
Inverter Technology
Inverter variable-speed duct-free split
systems are measurably quieter and
consume less energy than conventional
air conditioners. The inverter compressor
ramps up or down to match the required
room capacity and maintain the comfort
level. When the selected temperature
is reached, the inverter compressor
operates at low speed to maintain that
comfort level, thereby using less energy.

PRODUCT FEATURES AND BENEFITS
Single Zone
Wall Mounted Art Cool
Premier
Single zone systems are equipped with
inverter components that offer superior
load matching and long piping installation.
The product works for optimizing power
consumption in residential and small office
buildings. Utilizing multiple indoor wall mount
units each with custom temperature controls
allow for precise temperature settings in
each zone of the building. Single zone sys-
tems allow flexibility in interior design and
complement any decor.
Low Sound Levels
When outdoor units run at full load, they
have a quiet operating sound level. To pro-
mote a quiet, comfortable environment, the
LG single zone system indoor units operate
at sound levels as low as 25 dB(A) (17 dB(A)
in sleep mode) and the outdoor units as low
as 45 dB(A) at full load. All rotating compo-
nents are soft-started by the controller using
digitally controlled inverters, which reduce
undesirable noise caused by fans and com-
pressors cycling on and off.
Comfort Control at Its
Best
Unlike traditional air conditioning control
systems, which use thermostatic controls to
maintain room temperatures, LG single zone
inverter controls continuously vary the indoor
unit fan speed and refrigerant flow.
LG single zone one-to-one systems continu-
ously measure the room temperatures and
adjust system operations accordingly to
maintain set temperature.
The outdoor unit responds by varying the
compressor speed and outdoor fan mo-
tors as needed to maintain system operat-
ing pressure. As a result, the single zone
systems deliver targeted space temperature
control.
Inverter Driven
The twin rotary compressors are optimized
to maximize compressor efficiency, which
reduces power consumption and monthly
utility bills. This latest inverter technology
allows single zone system outdoor units to
vary the compressor motor shaft speed to
deliver an appropriate amount of cooling to
the indoor unit. Precise refrigerant volume
delivery translates into long periods with coil
surface temperatures below dew point and
minimizes compressor and fan component
run time which may lead to lower utility us-
age.
Simplified Installation
Cooling and heating applications that use
single zone systems simplify and reduce the
mechanical and control system design time.
The designer no longer has to be concerned
with interconnecting chilled and condenser
water piping, air-distribution duct systems,
matching and selecting chillers, towers,
pumps, coils, fans, air handlers, or Variable
Air Volume (VAV) boxes.
Operating Range
Single zone systems have a nominal capac-
ity range of 3/4 to 2 tons (depending on
outdoor/indoor units).
Outdoor unit operating ranges for single
zone systems:
Cooling: 14°F DB to 118°F DB
Heating: -13°F WB to 65°F WB
(Installing an optional Low Ambient Wind
Baffle Kit will allow operation down to 0°F in
cooling mode for these single zone sys-
tems.)
Compact Size
Single zone outdoor units have the following
footprint:
LAU090HYV1, LAU120HYV1:
(WxHxD [in.]) 30-5/16 x 21-1/2 x 11-5/16.
LAU150HYV2, LAU180HYV2
(WxHxD [in]) 34-1/4 x 31-1/2 x 12-5/8.
LAU180HYV1, LAU240HYV1
(WxHxD [in]) 34-1/4 x 31-1/2 x 12-5/8.
Fin Design with Gold-
Fin™ Coating
All single zone outdoor units are provided
with large surface coils made of copper
tubes with louvered aluminum fins designed
to maximize unit operating efficiency over a
wide range of ambient conditions.
Standard from the factory, every single zone
outdoor unit coil fin surface is coated with
LG’s exclusive GoldFin™ anti-corrosive
coating designed to prevent natural surface
corrosion of the aluminum fins. This main-
tains heat transfer properties of the coil for
an extended time.
A hydrophilic coating is applied to the
outdoor unit coil fin surface over the GoldFin
coating. This coating enhances the develop-
ment of heavier water droplets gathering on
the fin surface. As a result, the droplets roll
off the fin surfaces, delaying the point when
frost forms on the coil surface during heat-
ing operation. This coating also makes it
possible to easily clean the outdoor unit coil
using a mild soap.

out the need for a separate interface device. The main screen for LGMV shall allow user to
view the following real time data on one screen:
Additional screens can be accessed by tabs on the main screen:
1. Cycleview: Graphic of internal components including:
2. Setting: Converts metric values to imperial values.
3. Making Data: Recording of real time data to a separate file created to be stored on the
user’s computer.
4. Loading Data: Recorded data from a saved “.CSV” file can be loaded to create an LGMV
session.
5. Electrical Data: The lower half of main screen is changed to show the following:
• Compressors showing actual speeds
• EEVs
• IDUs
• Low and high pressures
• Temperature and pressure sensors
• Four-way reversing valve

EQUIPMENT SELECTION PROCEDURE
Cooling/Heating Correction Factors
For Single Zone Art Cool Premier systems, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, de-
termine the elevation difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction
factors as shown in the table below. Multiply the correction factors by the cooling or heating capacity obtained from the capacity tables using
design conditions. The resultant is the NET cooling or heating capacity.

BUILDING VENTILATION DESIGN GUIDE
Method 1: Decoupled Dedicated Outdoor Air System (DDOAS)
Provide a separate, dedicated outdoor-air system designed to filter, condition, and dehumidify ventilation air and deliver it directly to the con-
ditioned space through a separate register or grille. This approach requires a separate independent ventilation duct system not associated
with single zone systems.
Advantages
• May be used with single zone systems.
• The outdoor air unit may supply “neutral” air to the occupant space
even when the single zone system indoor unit fan changes speed
or cycles on and off. DDOAS controls do not have to be interlocked
with the single zone system.
• In lieu of installing localized smaller outside air treatment
equipment throughout the building, this method centralizes the
ventilation air source making service and filter changes easier and
less disruptive for the building occupants.
• Third-party demand control ventilation controls are more readily
accommodated.
Disadvantages
• Ceiling space is required to accommodate ductwork between the
centralized outdoor air unit and ceiling diffusers.
LG recommends using the DDOAS method in all installations.

Building Ventilation Design Guide
ASHRAE 62.1 and local codes specify the minimum volume of outdoor air that must be provided to an occupied space. Outdoor air is re-
quired to minimize adverse health effects, and it provides acceptable indoor air quality for building occupants. The three methods of accom-
plishing this with single zone systems are summarized here.
Although we believe that these building ventilation methods have been portrayed accurately, none of the methods have been tested, veried, or
evaluated by LG Electronics, U.S.A., Inc., In all cases, the designer, installer, and contractor should understand if the suggested method is used, it
is used at their own risk. LG Electronics U.S.A., Inc., takes no responsibility and offers no warranty, expressed or implied, in law or in fact, including
but not limited to any implied warranty of merchantability or tness for a particular purpose.
• For a complete copy of Standard 62.1-2010, refer to the American Standard of Heating and Air Conditioning Engineers (ASHRAE)
website at www.ashrae.org.
• For more information on how to properly size a ventilation air pretreatment system, refer to the article, “Selecting DOAS Equipment with
Reserve Capacity” by John Murphy, published in the ASHRAE Journal, April 2010.

BUILDING VENTILATION DESIGN GUIDE
Method 2: Unconditioned Outdoor Air (Non-Ducted, Natural Ventilation)
Natural ventilation devices, such as operable windows or louvers may be used to ventilate the building when local code permits. The open
area of a window or the free area of a louver must meet the minimum percentage of the net occupied floor area.
Advantages
• Occupants control the volume of the ventilation air manually.
• Useful for historic buildings that have no ceiling space available for
outdoor air ductwork.
• May be used with single zone systems.
Disadvantages
• In some locations, it may be difficult to control humidity levels when
windows are open.
• Thermal comfort levels may be substandard when windows are
open.
• Indoor units may have to be oversized to account for the added
heating and cooling loads when windows are open.
• Provides outdoor air to perimeter spaces only. Additional mechani-
cal ventilation system may be required to satisfy requirements for
interior spaces.
• Outdoor air loads may be difficult to calculate since the quantity of
outdoor air is not regulated.
• May affect indoor unit proper operation when open.
Method 3: Unconditioned Outdoor Air (Non-Ducted, Fan Assisted Ventilation)
When approved by local codes, the fan assisted ventilation method uses exhaust fans to remove air from the building, and outdoor air is
drawn into occupied spaces through a wall louver or gravity roof intake hood. Supply fans can also be used to push the outdoor air into the
space and building positive pressure will vent the exhaust air through louvers or roof-mounted exhaust hoods. Outdoor air is neither cooled
nor heated before entering the building.
Advantages
• Outdoor air may be manually controlled by the occupant or auto-
matic controls may be installed to open/close outdoor air dampers
or to turn on/off ventilation fans.
• Useful for large open spaces like warehouses, garages, and
workshops.
• Outdoor air volume is a known quantity. Air loads may be easier to
calculate since fans will regulate the amount of outdoor air.
• May be used with single zone systems.
Disadvantages
• In some locations of the country, it may be difficult to control
humidity levels while outdoor air louvers/hoods are opened.
• Thermal comfort levels may be substandard when louvers/hoods
are opened.
• Indoor units may have to be oversized to account for the added
heating/cooling loads when louvers/hoods are open.
• Hot, cold, and/or humid areas may be present if the outdoor air is
not evenly distributed to the different spaces.
This may result in loss of building pressurization control, increasing inltration loads with adverse effects.

PLACEMENT CONSIDERATIONS
Selecting the Best Location
DANGER
To avoid the possibility of re, do not install the unit in an area where combustible gas may generate, ow, stagnate, or leak. Failure to do so will
cause serious bodily injury or death.
Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Do not install the unit in a location
where acidic solution and spray (sulfur) are often used as this may cause serious bodily injury or death. Do not use the unit in environments
where oil, steam, or sulfuric gas are present as this may cause serious bodily injury or death.
Select a location for installing the outdoor unit that will meet the following conditions:
• Where there is enough strength to bear the weight of the unit.
• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode.
• Include enough space for air flow and for service access.
Dont's
• Where the unit will be subjected to direct thermal radiation from other heat sources.
• Where operating sound from the unit will disturb inhabitants of surrounding buildings.
• Where the unit will be exposed to direct, strong winds.
To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or
severe wind chill or cold:
1. Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these are unusual phenomena.
2. Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall. If snow piles up and blocks the airflow, the
system may malfunction.
3. Remove any snow that has accumulated by 4 inches or more on the top of the outdoor unit.
4. Place the outdoor unit on a raised platform at least 20 inches higher than the average annual snowfall for the area. In environments where
there is a possibility of heavy snow, the frame height must be more than two (2) times the amount of average annual snowfall, and should
not exceed the width of the outdoor unit. If the frame width is wider than the outdoor unit, snow may accumulate.
5. Install a snow protection hood.
6. To prevent snow and heavy rain from entering the outdoor unit, install the suction and discharge ducts facing away from direct winds.
7. Additionally, the following conditions should be taken into consideration when the unit operates in defrost mode:
• If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot
of natural light. (Example: Install on a rooftop.)
• Sidewalks or parking lots near the outdoor unit may accumulate moisture after unit operates in defrost mode that can turn to ice.
The indoor unit may take longer to provide heat, or heating performance will be reduced in winter if the unit is installed:
1. In a narrow, shady location.
2. Near a location that has a lot of ground moisture.
3. In a highly humid environment.
4. In an area in which condensate does not drain properly.
Ambient Air Conditions
• Avoid exposing the unit to discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumb-
ing vents, or substances that may degrade performance or cause damage to the unit.
• When installing multiple outdoor units, avoid placing the units where discharge of one outdoor unit will blow into the inlet side of an adja-
cent unit.
Avoid exposing the unit to sources of extreme temperature or gases to prevent serious bodily injury.

General Mounting for Outdoor Units
Securely attach the outdoor unit to a condenser pad, base rails, or
another mounting platform that is securely anchored to the ground
or building structure. Attach the outdoor unit with a bolt and nut on a
concrete or rigid mount. Refer to the applicable installation manual
and follow applicable local codes for clearance, mounting, anchor
and vibration attenuation requirements.
All referenced materials are to be eld-supplied. Images are not
to scale.

Foundation
Mounting Platform
The underlying structure or foundation must be designed to sup-
port the weight of the unit. Avoid placing the unit in a low lying area
where water may accumulate. When installing the outdoor unit on
the wal, or roof top, anchor the mounting base securely to account
for wind, earthquake or vibration.
Tie-Downs and Wind Restraints
The strength of the Single Zone system frame is adequate to
be used with field-provided wind restraint tie-downs. The overall
tie-down configuration must be approved by a local professional
engineer.
Always refer to local code when designing a wind restraint system.
Snow and Ice Conditions
In climates that experience snow build-up, place the unit on a raised platform to ensure condenser airflow. The raised support platform must
be high enough to allow the unit to remain above possible snow drifts. Mount the unit on a field-provided snow stand at a minimum height
that is equal to the average annual snowfall plus 20 inches. Design the mounting base to prevent snow accumulation on the platform in front
or back of the unit case. If necessary, provide a field fabricated hood to keep snow and ice and/or drifting snow from accumulating on the coil
surfaces. Use inlet and discharge duct or hoods to prevent snow or rain from accumulating on the fan inlet and outlet guards. Best practice
prevents snow from accumulating on top of the unit. Consider tie-down requirements in case of high winds or where required by local codes.
More than 5 inches
More than
4 inches
More than
4 inches
At least 6.5 feet from the floor
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on
sidewalks or driveways which may create unsafe conditions.
CAUTION
Follow recommended best practices when choosing an indoor location for the
single zone indoor unit.
• Use a metal detector to locate studs in the walls. Anchor unit following stud
location, to prevent damage to the wall.
• Clearance gap between any wall or enclosure and the left or right side of the
unit must be greater than 4 inches.
• Minimum clearance of the indoor unit from its top to the ceiling is 5 inches.
• Unit should be at least 6.5 feet from the oor for adequate clearance.
• Keep unit away from any indoor steam or excessive heat.
• No obstacles should be placed around unit.
• Condensation drain (leakage piping) should be routed away from the unit.
• Do not install near doorway.
If the outdoor unit is installed between standard and minimum
clearances, capacity decreases approximately 10 to 20%.

Outdoor Unit Clearances
PLACEMENT CONSIDERATIONS
Minimum Clearance Requirements for Single Zone Art Cool Premier Systems
Proper clearance for the outdoor unit coil is critical for proper unit operation. When installing the outdoor unit, consider service, inlet and
outlet and minimum allowable space requirements as illustrated in the diagrams below.
Specific clearance requirements in the diagram below are for the Single Zone Wall Mounted Art Cool Premier systems. Figure 13 shows the
overall minimum clearances that must be observed for safe operation and adequate airflow around the outdoor unit.
When placing the outdoor unit under an overhang, awning, sunroof or other “roof-like structure”, observe the clearance requirements (as
shown in Cases 1 and 2 in Figure 13) for height in relation to the unit. This clearance ensures that heat radiation from the condenser is not
restricted around the unit.
Adhere to all clearance requirements if installing the unit on a roof. Be sure to level the unit and ensure that the unit is adequately anchored.
Consult local codes for rooftop mounting requirements.
In order to have successful service access to the outdoor unit, see Figure 13 for minimum spacing. When installing multiple outdoor units,
see Cases 4 and 5 in Figure 13 for correct spacing requirements.

3. Calculate the equivalent pipe length of each pipe segment.
Using Elbows
Field-supplied elbows are allowed as long as they are long radius and designed
for use with R410A refrigerant. The designer should be cautious with the quantity
and size of fittings used, and must account for the additional pressure losses in
equivalent pipe length calculation. The equivalent pipe length of each elbow must
be added to each pipe segment. See the table for equivalent lengths.

Refrigerant Piping Design & Layout Best Practices
Field-Provided Isolation Ball Valves
LG maintains a neutral position on using isolation valves in refrigerant piping systems. LG does not endorse any manufacturer of isolation
valves. It is recognized that installing isolation valves may simplify future maintenance requirements, and, if used, considerations should be
taken including, but not limited to, the following:
• Pressure drops for any component used, including isolation valves, must be known in equivalent pipe length and calculated into the total
and segment equivalent piping lengths and compared to product design limitations.
• In all cases, materials must be suitable for the application and any applicable codes, including, but not limited to, diameter and wall thick-
ness continuity per ACR standards.
Failure to do so may cause significant performance degradation. Proper leak checks must be performed. Using isolation valves does not
automatically void any LG product warranty, however, a limited warranty may be voided in whole or part should any field supplied accessory
fail in any way that causes product failure.
Refrigerant Piping System Layout
INSTALLATION & LAYOUT BEST PRACTICES
No Pipe Size Substitutions
Using a different size is prohibited and may result in a system malfunction or failure to work at all.
In-line Refrigeration Components
Components such as oil traps, solenoid valves, filter-dryers, sight glasses, tee fittings, and other after-market accessories are not permitted
on the refrigerant piping system between the outdoor unit and the indoor unit. Single Zone Wall Mounted Art Cool Premier air-source systems
are provided with redundant systems that ensure oil is properly returned to the compressor. Sight-glasses and solenoid valves may cause
vapor to form in the liquid stream. Over time, dryers may deteriorate and introduce debris into the system. The designer and installer verify
the refrigerant piping system is free of traps, sagging pipes, sight glasses, filter dryers, etc.
Pipe Supports
A properly installed pipe system should be adequately supported to avoid pipe sagging. Sagging pipes become oil traps that lead to equip-
ment malfunction. Pipe supports should never touch the pipe wall; supports shall be installed outside (around) the primary pipe insulation
jacket. Insulate the pipe first because pipe supports shall be installed outside (around) the primary pipe insulation jacket. Clevis hangers
should be used with shields between the hangers and insulation. Field provided pipe supports must meet local codes. If allowed by code, use
fiber straps or split-ring hangers suspended from the ceiling on all-thread rods (fiber straps or split ring hangers can be used as long as they
do not compress the pipe insulation). Place a second layer of insulation over the pipe insulation jacket to prevent chafing and compression of
the primary insulation within the confines of the support pipe clamp.
A properly installed pipe system will have sufficient supports to avoid pipes from sagging during the life of the system. As necessary, place
supports closer for segments where potential sagging could occur. Maximum spacing of pipe supports must meet local codes.
If local codes do not specify pipe support spacing, pipe must be supported:
• Maximum of five feet (5′) on center for straight segments of pipe up to 3/4" outside diameter size.
• Wherever the pipe changes direction, place a hanger within twelve (12) inches on one side and within twelve to nineteen (12 to 19) inches
of the bend on the other side as shown.

Obstacles
When an obstacle, such as an I-beam or concrete T, is in the path
of the planned refrigerant pipe run, it is best practice to route the
pipe over the obstacle. If adequate space is not available to route
the insulated pipe over the obstacle, then route the pipe under the
obstacle. In either case, it is imperative the horizontal section of pipe
above or below the obstacle be a minimum of three (3) times greater
than the longest vertical rise (or fall) distance.

Pipe Sleeves at Penetrations
LG requires that all pipe penetrations through walls, floors, and pipes buried underground be properly insulated and routed through an
appropriate wall sleeve of sufficient size to prevent compression of refrigerant pipe insulation and free movement of the pipe within the
sleeve. Underground refrigerant pipe shall be routed inside a protective sleeve to prevent insulation deterioration See figure below.
Figure 20: Pipe Sleeve Options.
Underground Refrigerant Piping
Refrigerant pipe installed underground should be routed inside a
vapor tight protective sleeve to prevent insulation deterioration and
water infiltration. Refrigerant pipe installed inside underground
casing must be continuous without any joints. Underground refriger-
ant pipe must be located at a level below the frost line.

Piping
Figure 27: Refrigerant Pipe Brazing.
It is imperative to keep the piping system free of contaminants and debris such as copper burrs, slag, or carbon dust during installation.
All joints are brazed in the field. Single Zone Wall Mounted Art Cool Premier
refrigeration system components contain very small capillary tubes, small orifices,
electronic expansion valves, oil separators, and heat exchangers that can easily
become blocked. Proper system operation depends on the installer using best
practices and utmost care while assembling the piping system.
• While brazing, use a dry nitrogen purge operating at a minimum pressure of three
(3) psig and maintain a steady flow.
• Blow clean all pipe sections with dry nitrogen prior to assembly.
• Use a tubing cutter,
do not use a saw to cut pipe. De-burr and clean all cuts
before assembly.
• Store pipe stock in a dry place. Keep pipe capped and clean.
• Use adapters to assemble different sizes of pipe.
• Do not use flux, soft solder, or anti-oxidant agents.
• Use a 15% silver phosphorous copper brazing alloy to avoid overheating and produce good flow.
• Protect isolation valves, electronic expansion valves, and other heat-sensitive control components from excessive heat with a wet rag or a
heat barrier spray product.
Refrigerant Piping System Insulation
All refrigerant piping, field-provided isolation ball valves, service valves, and long radius elbows shall be completely insulated using closed
cell pipe insulation. The liquid and vapor lines must be insulated separately.
To prevent heat loss/heat gain through the refrigerant piping, all refrigerant piping including liquid lines and vapor lines shall be insulated
separately. Insulation shall be a minimum 1/2″ thick, and thickness may need to be increased based on ambient conditions and local codes.
All insulation joints shall be glued with no air gaps. Insulation material must fit snugly against the refrigeration pipe with no air space between
it and the pipe. Insulation passing through pipe hangers, inside conduit, and/or sleeves must not be compressed. Protect insulation inside
hangers and supports with a second layer. All pipe insulation exposed to the sun and outdoor elements shall be properly protected with PVC,
aluminum vapor barrier, or alternatively placed in a weather-resistant enclosure such as a pipe rack with a top cover, and meet local codes.
The design engineer should perform calculations to determine if the factory-supplied insulation jackets are sufficient to meet local codes and
avoid sweating. Add additional insulation if necessary. Mark all pipes at the point where the insulation jacket ends. Remove the jacket. Install
field-provided insulation on the run-out and main truck pipes first. Peel the adhesive glue protector slip from the insulation jacket and install
the clam-shell jacket over the fitting.
Charging
Each outdoor unit is factory charged (nameplate charge) for the
evaporator as well as a standard 41 foot (9k, 12k HYV1 ) or 25 foot
(15k, 18k HYV2; 18k, 24k HYV1) line. Any time a line set is used
longer then the standard line set length, the refrigerant charge has to
be adjusted.
You must adjust the charge based on how many feet of piping are
added based on 0.22 or 0.38 oz. of R410A per foot. The factory
charge accommodates pipe lengths up to the standard length without
requiring refrigerant removal.
Example: A 50 ft line set is used --
9 additional feet x 0.22 oz per ft = Add 1.98 oz
of R410A
If you are uncertain of the unit charge, reclaim, evacuate and weigh
in the correct charge using the unit nameplate (capacity) charge
adjusting for line sets longer than 24.6 or 41 ft. This will prevent any
interruptions to the functioning of the unit and possible damage.
