  • Page 5: Lats Overview

    ® 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.

    APPLICATION GUIDELINES General Mounting General Mounting - Wall-Mounted 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.
