Power Supply / Power Wiring Specifications
Outdoor unit(s) and Hydro Kits must be provided power from separate breakers. For detailed information, see the Multi V Outdoor Unit Engi-
neering and Installation Manuals on www.lghvac.com.
Hydro Kits
• Hydro Kits require 1Ø, 208-230V, 60Hz power (maximum ac-
ceptable power fluctuation range is 187V to 253V), but each
unit draws minimal power. See Hydro Kit Electrical Data table at
right.
• Where permitted by NEC and local codes, multiple Hydro Kits
(and indoor units / heat recovery units) can be powered from a
single breaker.
• Service switches typically must be installed for each Hydro Kit
(and each indoor unit / each heat recovery unit).
• Ground each Hydro Kit (and indoor unit / heat recovery unit) separately to a solid earth ground source per NEC and local code require-
ments.
WARNING
• All power wiring installation must be performed by trained service providers working in accordance with local, state, and NEC regulations
related to electrical equipment and wiring, and following the instructions in this manual. Failure to do so will lead to electric shock and bodily
injury or death.
•
it will generate heat and / or cause a fire, resulting in physical injury or death.
• Install appropriately sized breakers / fuses / overcurrent protection switches and wiring in accordance with local, state, and NEC regulations
related to electrical equipment and wiring, and following the instructions in this manual. Generated overcurrent will include some amount of
direct current. Using an oversized breaker or fuse will result in electric shock, physical injury or death.
• Use the appropriate type of overcurrent protection. Generated overcurrent will include some amount of direct current, and if the appropriate
type of overcurrent protection is not installed, there is a risk of fire, electric shock, and physical injury or death.
• Ground wiring is required to prevent accidental electrical shock during current leakage, communication problems from electrical noise, and mo-
tor current leakage.
•
• Install appropriately sized breakers / fuses / overcurrent protection switches and wiring in accordance with local, state, and NEC regulations
related to electrical equipment and wiring, and following the instructions in this manual. Generated overcurrent could include some amount
of direct current. Using an oversized breaker or fuse will result in equipment malfunction and property damage.
• Do not connect ground wire to refrigerant, gas, or water piping; to lightning rods; to telephone ground wiring; or to the building plumb-
ing system. Failure to properly provide a National Electrical Code-approved earth ground can result in property damage and equipment
malfunction.
