Condensate Pump / Drain Installation
Description Check
Condensate piping installed correctly on indoor units. Material used is acceptable under local code. Insulated as necessary to
prevent condensation.
All condensate vertical risers are equal to or less than 27-1/2 inches from the bottom of the indoor unit.
Indoor units with condensate pumps were level. Units with gravity drains were level or slightly canted toward the drain connection
and are supported properly.
Pumped condensate drain lines were properly connected (do not have traps, and connect to the top surface of the main drain
line).
Multi F / Multi F MAX with LGRED gravity condensate drain line was connected and routed where it properly drains away or, if
installed in a mechanical room, was connected and properly routed to a drain terminal.
All condensate lines were properly insulated to prevent condensation.
Power Wire and Communications Cables
Description Check
Ground wire was installed and properly terminated at the unit.
Power wiring was connected to a single phase 208-230V source.
The power supplied was clean with voltage fluctuations within specifications (±10% of nameplate).
Power wiring to the Multi F / Multi F MAX with LGRED outdoor unit was field supplied, solid or stranded, and installed per all local,
state, and NEC requirements.
All communications / connection (power) cable from the Multi F with LGRED outdoor unit to the indoor units is to be minimum four
conductor, 18 AWG stranded, shielded or unshielded (if shielded, it must be grounded to the chassis of the outdoor unit only), and
must comply with applicable local and national codes.
All power wiring / communication cable to be minimum 16 AWG from the Multi F MAX with LGRED outdoor unit to the BD unit, and
18 AWG from the branch distribution unit to the indoor units, stranded, shielded or unshielded (if shielded, it must be grounded to
the chassis of the outdoor unit only), and must comply with applicable local and national codes.
Power wiring to the outdoor unit and communication / connection (power) cable from the outdoor unit to the indoor units or branch
distribution units (Multi F MAX with LGRED only) were separated per manufacturer’s guidelines. These cannot be run in the same
conduit.
Communications / connection (power) cable were run in the same conduit (outdoor unit to indoor unit or branch distribution unit
[Multi F MAX with LGRED only] as provided in the product installation manual.
Proper communications cable was used between each indoor unit and its zone controller where applicable. No cables were
spliced and no wire nuts are present.
Communication type RS-485–BUS type.
Used appropriate crimping tool to attach ring or fork terminals at all power wiring and control cable terminations.
Only LG-supplied Y-cables were used between grouped indoor units, if applicable.
