LATS MULTI V PIPING
DESIGN SOFTWARE
The proper design and installation of the refrigerant piping system
is a critical element of a Multi V system. Multi V Heat Pump systems
require two pipes between components – a liquid line and a vapor
line. Multi V Heat Recovery systems require three pipes between the
outdoor unit and the heat recovery unit – a liquid line, a low-pressure vapor line, and a high-pressure vapor line. A properly designed
refrigerant piping system ensures that refrigerant is delivered to the
indoor unit coils for optimal system performance and capacity.
LG Air Conditioner Technical Solution (LATS) software is a total
design solution for LG Multi V air conditioning systems. This
Windows®-based application assists the design engineer with
specifying and sizing outdoor and indoor units (by calculating
component capacity based on design conditions), laying out the
refrigeration distribution pipe system, checking piping limitations,
calculating refrigerant charge, and generating equipment schedules
and piping diagrams in (.dxf) format for use on CAD building design
drawings.*
* Windows® is a registered mark of Microsoft® Corporation.
Introduction
To ensure that the refrigerant piping design meets LG’s quality standards, a LATS refrigerant piping design must be provided with
every Multi V order. Following the installation, if any changes or variations to the design are necessary, a new LATS file must be
created and provided to LG prior to system commissioning to ensure the proper pipe size has not changed.
Design Choices
LATS Multi V software is flexible, offering the HVAC system engineer an easy to use Tree mode.
Tree Mode
Using the Tree mode, the engineer can quickly create a one-line schematic drawing of a Multi V system. Integration of the engineered pipe
system into the building drawings is done at a later date by the draftsperson using standard drafting software tools.
• Import building loads from an external file (.xls format).
• System components selected using an easy drag and drop process.
• Automatically analyzes and checks the design complies with most
piping design limitations.
• Sizes refrigerant piping.
• Generates a system engineering report (.xls format).
• Generates an equipment schedule (.xls or .dxf format).
• Generates a system piping diagram (.dxf format).
Figure 1: Screenshot of LATS Pipe System Design Tool in Tree Mode.
LATS Report
LATS Multi V software generates a report file (.xls format) containing
project design parameters, cooling and heating design day system
component performance, and capacity data. The report calculates
the system combination ratio, calculates the system refrigerant
charge, and provides detailed bill of material information including a
list of Multi V outdoor units, air handlers, control devices, accessories, refrigerant pipe sizes segregated by building, by system, by pipe
size, and by pipe segments.

Casing
Units are designed to mount on a vertical surface and come complete with an installation mounting guide and a separate hanging
bracket. The unit case is manufactured with coated metal. Cold
surfaces are covered with a coated polystyrene insulating material.
MULTI V Wall-Mounted Indoor Unit Engineering Manual
Finish
The unit case has a light gray / silver matte finish. The front surface
of the unit has a flat glass panel and frame that can accommodate a
Ǝ[ƎSKRWRJUDSKSLFWXUHRUDUWZRUN
Fan Assembly and Control
The indoor unit has a single, direct-drive, turbo fan. The fan wheel
is made of high strength ABS HT-700 polymeric resin. The fan motor
is a Brushless Digitally Controlled (BLDC) design with permanently
lubricated and sealed ball bearings. The fan motor includes thermal,
overcurrent and low RPM protection. The fan/motor assembly is
mounted on vibration attenuating rubber grommets. The fan impeller
is statically and dynamically balanced. The fan speed is controlled
using a microprocessor-based, direct digital control algorithm that
provides a high fan speed in cooling thermal ON and low fan speed
in cooling thermal OFF, high fan speed in heating thermal ON and
fan off in heating thermal OFF. The fan speeds can be field adjusted
between low, medium, and high speeds. The fan speed algorithm
provides a field selectable, fixed-speed or auto-speed setting that
adjusts the fan speed to simulate natural airflow.
Air Filter
Return air is filtered with a removable, washable filter with anti-fungal treatment. Filter access is from the front of the unit without the
use of tools.
Airflow Guide Vanes
The indoor unit is provided with motorized sweeping guide vanes
that automatically change the direction of airflow from side-to-side
and up-and-down.
Microprocessor Control
The unit is provided with an integrated microprocessor controller capable of performing functions necessary to operate the system without the use of a wall-mounted controller. A temperature thermistor is
factory mounted in the return air stream. All unit operation parameters, excluding the operating schedule, are stored in non-volatile
memory resident on the unit microprocessor. Operating schedules
are stored in select models of the optional, wall-mounted, local or
central controllers. The field-supplied communication cable between
the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG,
2 conductor, stranded, and shielded cable (RS-485), terminated via
screw terminals on the control boards. The microprocessor control
provides the following functions: auto addressing, self-diagnostics,
auto restart following power restoration, test run, and will operate the
indoor unit using one of five operation modes:
1.
2.
3.
4.

systems, heated or cooled air delivery
is dependent upon outdoor unit
operating mode.
In Heating mode, the microprocessor
control will activate indoor unit operation when the indoor room temperature
falls below set-point temperature.
At which point, a signal is sent to
the outdoor unit to begin the heating
cycle. The indoor unit fan operation
is delayed until coil pipe temperature
reaches 76°F. Significant airflow is
generated when pipe temperature
reaches 80°F. A field-selectable option maintains fan operation for
30 minutes following cooling cycle operations. The unit is equipped
with an infrared receiver designed to communicate with an LG
wireless remote controller. In lieu of wireless remote or factory return
air thermistor, screw terminals on the microprocessor circuit board
accommodate various models of wall-mounted local controllers.
The unit microprocessor is capable of accepting space temperature
readings concurrently or individually from either:
1. Wall-mounted wired controller(s)
2. Factory-mounted return air thermistor
A single indoor unit has the capability of being controlled by up to
two local wired controllers. The microprocessor controls space temperature using the value provided by the temperature sensor sensing
a space temperature that is farthest away from the temperature
set-point. The microprocessor control provides a cooling or heating
mode test cycle that operates the unit for eighteen (18) minutes
without regard to the space temperature. If the system is provided
with an optional wall-mounted local or central controller, displayed diagnostic codes are specific, alpha-numeric, and provide the service
technician with a reason for the code displayed.
Handling Condensate
The unit is designed for gravity draining of condensate. LG provides
a factory insulated flexible drain hose. If condensate lift/pumps are
needed for the application, they are to be field provided.
Condensate Drain Pan
The condensate drain pan is constructed of expandable polystyrene
resin (EPS).
Coil
The indoor unit coil is constructed with grooved design copper tubes
with slit coil fins, two (2) rows, eighteen (18) fins per inch.

Units are designed to mount on a vertical surface and come complete with an installation mounting guide and a separate hanging
bracket. The unit case is manufactured with coated metal. Cold
surfaces are covered with a coated polystyrene insulating material.
Finish
MULTI V Wall-Mounted Indoor Unit Engineering Manual
The unit case has a light gray / silver matte finish. The front surface
of the unit has an architectural flat panel smoked mirror finish.
Fan Assembly and Control
The unit has a single, direct-drive, crossflow tangential Sirocco fan
made of high strength ABS BSN-7530 polymeric resin. The fan motor
is a Brushless Digitally Controlled (BLDC) design with permanently
lubricated and sealed ball bearings. The fan motor includes thermal,
overcurrent and low RPM protection. The fan / motor assembly is
mounted on vibration attenuating rubber grommets. The fan impeller
is statically and dynamically balanced. The fan speed is controlled
using a microprocessor-based direct digital control algorithm that
provides a high fan speed in cooling thermal ON and low fan speed
in cooling thermal OFF, high fan speed in heating thermal ON and
fan off in heating thermal OFF. The fan speeds can be field adjusted
between low, medium, and high speeds. The fan speed algorithm
provides a field-selectable fixed-speed or auto-speed setting that
changes the fan speed to simulate natural airflow.
Air Filter
Return air is filtered with a removable, washable filter with anti-fungal treatment. Filter access is from the front of the unit without the
use of tools.
Airflow Guide Vanes
5–15 MBh
The indoor unit is provided with a motorized oscillating guide vane
that automatically changes the direction of up-and-down airflow.
The indoor unit includes factory installed, manually adjustable guide
vanes that control the side-to-side direction of supplied airflow.
For Heat Recovery
systems the Auto
Changeover setting automatically
switches control
of the indoor unit
between Cooling
and Heating modes based on space temperature conditions.
For Heat Pump systems, heated or cooled air delivery is dependent
upon outdoor unit operating mode. In Heating mode, the microprocessor control will activate indoor unit operation when the indoor
room temperature falls below set-point temperature. At which point,
a signal is sent to the outdoor unit to begin the heating cycle. The indoor unit fan operation is delayed until coil pipe temperature reaches
76°F. Significant airflow is generated when pipe temperature reaches
80°F. A field-selectable option maintains fan operation for 30 minutes
following cooling cycle operations. The unit is equipped with an infrared receiver designed to communicate with an LG wireless remote
controller. In lieu of wireless remote or factory return air thermistor,
screw terminals on the microprocessor circuit board accommodate
various models of wall-mounted local controllers. The unit microprocessor is capable of accepting space temperature readings concurrently or individually from either:
1. Wall-mounted wired controller(s)
2. Factory-mounted return air thermistor
A single indoor unit has the capability of being controlled by up to
two local wired controllers. The microprocessor controls space temperature using the value provided by the temperature sensor sensing
a space temperature that is farthest away from the temperature
set-point. The microprocessor control provides a cooling or heating
mode test cycle that operates the unit for 18 minutes without regard
to the space temperature. If the system is provided with an optional
wall-mounted local or central controller, displayed diagnostic codes
are specific, alpha-numeric, and provide the service technician with a
reason for the code displayed.
18-24 MBh
Handling Condensate
The indoor unit is provided with a motorized sweeping guide vane
that automatically changes the direction of airflow from side-to-side
and up-and-down.
The unit is designed for gravity draining of condensate. LG provides
a factory insulated flexible drain hose. If condensate lift / pumps are
needed for the application, they are to be field provided.
Microprocessor Control
Condensate Drain Pan
The unit is provided with an integrated microprocessor controller capable of performing functions necessary to operate the system without the use of a wall-mounted controller. A temperature thermistor is
factory mounted in the return air stream. All unit operation parameters, excluding the operating schedule, are stored in non-volatile
memory resident on the unit microprocessor. Operating schedules
are stored in select models of the optional, wall-mounted, local or
central controllers. The field-supplied communication cable between
the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG,
2 conductor, stranded, and shielded cable (RS-485), terminated via
screw terminals on the control boards. The microprocessor control
provides the following functions: auto addressing, self-diagnostics,
auto restart following power restoration, test run, and will operate the
indoor unit using one of five operation modes:

Casing
Units are designed to mount on a vertical surface and come complete with an installation mounting guide and a separate hanging
bracket. The unit case is manufactured with coated metal. Cold
surfaces are covered with a coated polystyrene insulating material.
Finish
MULTI V Wall-Mounted Indoor Unit Engineering Manual
The unit case is manufactured using ABS polymeric resin and has a
pearl white finish.
Fan Assembly and Control
The unit has a single, direct-drive, crossflow tangential Sirocco fan
made of high strength ABS BSN-7530 polymeric resin. The fan motor
is a Brushless Digitally Controlled (BLDC) design with permanently
lubricated and sealed ball bearings. The fan motor includes thermal,
overcurrent and low RPM protection. The fan/motor assembly is
mounted on vibration attenuating rubber grommets. The fan impeller
is statically and dynamically balanced. The fan speed is controlled
using a microprocessor-based direct digital control algorithm that
provides a high fan speed in cooling thermal ON and low fan speed
in cooling thermal OFF, high fan speed in heating thermal ON and
fan off in heating thermal OFF. The fan speeds can be field adjusted
between low, medium, and high speeds. The fan speed algorithm
provides a field-selectable fixed-speed or auto-speed setting that
changes the fan speed to simulate natural airflow.
Air Filter
Return air is filtered with a removable, washable filter with anti-fungal treatment. Filter access is from the front of the unit without the
use of tools.
Airflow Guide Vanes
5–15 MBh
The indoor unit is provided with a motorized oscillating guide vane
that automatically changes the direction of up-and-down airflow.
The indoor unit includes factory installed, manually adjustable guide
vanes that control the side-to-side direction of supplied airflow.
18-36 MBh
The indoor unit is provided with a motorized sweeping guide vane
that automatically changes the direction of airflow from side-to-side
and up-and-down.
Microprocessor Control
The unit is provided with an integrated microprocessor controller capable of performing functions necessary to operate the system without the use of a wall-mounted controller. A temperature thermistor is
factory mounted in the return air stream. All unit operation parameters, excluding the operating schedule, are stored in non-volatile
memory resident on the unit microprocessor. Operating schedules
are stored in select models of the optional, wall-mounted, local or
central controllers. The field-supplied communication cable between
the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG,
2 conductor, stranded, and shielded cable (RS-485), terminated via
screw terminals on the control boards. The microprocessor control
provides the following functions: auto addressing, self-diagnostics,
auto restart following power restoration, test run, and will operate the
indoor unit using one of five operation modes:
1. Auto Changeover (Heat Recovery only)
2. Heating
3. Cooling
4. Dry
5. Fan Only
42
|
STANDARD
For Heat Recovery systems
the Auto Changeover setting
automatically switches
control of the indoor unit
between Cooling and Heating modes based on space
temperature conditions.
For Heat Pump systems, heated or cooled air delivery is dependent
upon outdoor unit operating mode.
In Heating mode, the microprocessor control will activate indoor unit
operation when the indoor room temperature falls below set-point
temperature. At which point, a signal is sent to the outdoor unit to
begin the heating cycle. The indoor unit fan operation is delayed until
coil pipe temperature reaches 76°F. Significant airflow is generated
when pipe temperature reaches 80°F. A field-selectable option
maintains fan operation for 30 minutes following cooling cycle
operations. The unit is equipped with an infrared receiver designed
to communicate with an LG wireless remote controller. In lieu of
wireless remote or factory return air thermistor, screw terminals on
the microprocessor circuit board accommodates various models of
wall-mounted local controllers. The unit microprocessor is capable
of accepting space temperature readings concurrently or individually
from either:
1. Wall-mounted wired controller(s)
2. Factory-mounted return air thermistor
A single indoor unit has the capability of being controlled by up to
two local wired controllers. The microprocessor controls space temperature using the value provided by the temperature sensor sensing
a space temperature that is farthest away from the temperature
set-point. The microprocessor control provides a cooling or heating
mode test cycle that operates the unit for 18 minutes without regard
to the space temperature. If the system is provided with an optional
wall-mounted local or central controller, displayed diagnostic codes
are specific, alpha-numeric, and provide the service technician with a
reason for the code displayed.
Handling Condensate
The unit is designed for gravity draining of condensate. LG provides
a factory insulated flexible drain hose. If condensate lift/pumps are
needed for the application, they are to be field provided.
Condensate Drain Pan
The condensate drain pan is constructed of expandable polystyrene
resin (EPS).
Coil
The indoor unit coil is constructed with grooved design copper tubes
with slit coil fins, two (2) rows, eighteen (18) fins per inch.

General Mounting
Wall-mounted indoor units have several options on how the piping and wiring can be routed (see figures below). Whichever way the piping
and wiring are routed out of the indoor units, the mounting wall on which the indoor unit is installed should be strong and solid enough to
protect it from vibration.
• Mount the installation plate on the wall using the Type “A” screws. If mounting the unit on concrete, consider using anchor bolts.
• Always mount the installation plate horizontally. Measure the wall and mark the centerline using thread and a level.

General Drain Piping Information
General Drain Piping Information
All Gallery and Wall-mounted indoor units generate water during
cooling operation, therefore, properly handling this condensation
must be considered. Gallery and Wall-mounted indoor units apply
the gravity drain method, but a field-supplied condensate pump can
be installed (optional, sold separately). Depending on the location of
the indoor unit, condensation can be drained directly to the outside
of the building, or a common indoor unit drainage piping system can
be installed.
Drain Hose
Gallery and Wall-mounted indoor units have a built-in drain hose.
If necessary, the drain hose can be extended. When the bottom
surface of the indoor unit is at an elevation below the receiving
building drain line connection, install an inverted trap at the top of the
condensate pump discharge riser before connection to the building
drain pipe.
If connecting to a vertical drain line or plumbing system vent line,

Application Guidelines
When the receiving drain line is mounted horizontal, connect the
inverted trap to the top half of the pipe. The connection point of the
inverted trap to the building drain pipe should always be to the top
half of the pipe and should never be over 45° either side of the upper
most point of the horizontal building drain line.

General Drain Piping Information
Common Indoor Unit Drainage System
MULTI V Wall-Mounted Indoor Unit Engineering Manual
It is usual work practice to connect individual indoor unit drain pipes to one common indoor unit drainage system. The diameter of the common vertical drain pipe should be as large as necessary. The diameter of the horizontal pipe should be the same or larger than the vertical
drain pipe. To avoid property damage in the event of the primary drain becoming clogged, and to optimize drain system performance, it may
be prudent to install a secondary drain line. Design the drain system to plan for winter operation (condensate line may freeze up if condensate does not properly drain away). Drain all generated condensate from the external condensate pan to an appropriate area. Install a trap
in the condensate lines as near to the indoor unit coil as possible. To prevent overflow, the outlet of each trap should be positioned below its
connection to the condensate pan. All traps should be primed, insulated, and leak tested if located above an inhabited space.
