Condensate Pump / Drain Installation
Description
Condensate piping installed correctly on indoor units. Material used is acceptable under local code. Insulated as necessary to
prevent condensation.
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 (no traps, and connect to the top surface of
the main drain line).
Multi F-Multi F MAX / Multi F-Multi F MAX with LGRED outdoor unit 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
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 / Multi F / Multi F MAX with LGRED outdoor unit was field supplied, solid or stranded,
and installed per all local, state, and NEC requirements.
For Multi F / Multi F with LGRED Systems
• Communication / connection (power) wiring from the outdoor unit to the indoor unit is minimum 14 gauge, four-conductor, stranded,
shielded or unshielded. If shielded, must be grounded to chassis at the outdoor unit only.
• Use of 14 AWG, four (4) conductor, stranded, shielded or unshielded wire is allowed for lengths up to the published maximum pipe
length, plus recommended slack at both ends.
For Multi F MAX / Multi F MAX with LGRED Systems
• All power wiring / communication cable to be minimum 14 AWG from the Multi F MAX outdoor unit to the BD unit 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.
• Communication / connection (power) wiring from the BD unit to the indoor unit is minimum 14 gauge, four-conductor, stranded,
shielded or unshielded. If shielded, must be grounded to chassis at the BD unit only.
• Use of 14 AWG, four (4) conductor, stranded, shielded or unshielded wire is allowed for lengths up to the published maximum
pipe length, plus recommended slack at both ends.
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 / 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 / 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.
