Installing the Remote Controller Batteries
As part of the test run, two (2) AAA (1.5V) batteries need to be inserted into the remote controller, and the remote controller may need to be
powered on to operate the indoor units (depending on the indoor units included in the system). To insert the batteries follow the steps below. For
information on using the remote controller, refer to its owner’s manual.
Multi F Systems
Additional charge (oz.) = (Installed Length of Branch [A] – Chargeless Pipe Length [L]) x a
+ (Installed Length of Branch [B] – Chargeless Pipe Length [L]) x a
+ (Installed Length of Branch [C] – Chargeless Pipe Length [L]) x a
+ (Installed Length of Branch [D] – Chargeless Pipe Length [L]) x a
- CF (Correction Factor) x 5.29
Multi F MAX Systems
Additional charge (oz.) = (Total Main Piping Length [A] - Chargeless Pipe Length of Main Pipe [L]) x a
+ (Installed Length of Branch [B1] – Chargeless Pipe Length [B]) x b
+ (Installed Length of Branch [B2] – Chargeless Pipe Length [B]) x b
+ (Installed Length of Branch [B3] – Chargeless Pipe Length [B]) x b ...
- CF (Correction Factor) x 3.53
• Number of installed length of branches depends on system specications.
• CF = Maximum number of connectible indoor units – Total number of connected indoor units
Refrigerant Charge
LG Multi F and Multi F MAX outdoor units ship from the factory with a charge of R410A refrigerant. A trim charge may need to be added to take
into account additional piping length. To find the R410A factory charge of each outdoor unit, see the Multi F / Multi F MAX Outdoor Unit Installa-
tion Manuals.
To determine the additional refrigerant that is needed, apply the formulas below, and record the results. If the total additional refrigerant charge
value is a negative number, then an additional trim charge does not need to be added to the system.
Optional Modes
Multi F and Multi F MAX outdoor units include optional functions such as mode locks for
cooling and heating, night quiet modes, and others. The modes are set by powering off
the system, setting the applicable DIP switches on the PCB of the outdoor unit, and then
turning the power back on. These modes must only be set by an authorized, trained and
licensed technician during the installation process. For a complete list of optional modes
that are available for specific outdoor units, and the detailed procedures necessary to
properly set the modes, see the complete Multi F / Multi F MAX Installation Manual.
WARNING
The circuit breaker must be turned off or the power source of the product must be shut
off before setting the DIP switch. There is risk of physical injury or death due to electric
shock.
• Unless the applicable DIP switch is set properly, the system may not work.
• If a specic function is desired, request that the installer set the appropriate DIP switch
during installation.
