Power wiring is field supplied and must comply with the applicable local and national

codes.

This unit comes with a dry nitrogen charge.

All capacities are net with a combination ratio between 95-105%.

Rated capacity is certified under AHRI Standard 1230. Ratings are subject to change

without notice. Current certified ratings are available at

www.ahridirectory.org

Max. power input is rated at maximum setting value.

Low ambient performance with LGRED° heat technology is included in Multi V 5 Air

Source Units produced after February 2019.

Take appropriate actions at the end of HVAC equipment life to recover, recycle, reclaim or

destroy R410A refrigerant according to applicable regulations (40 CFR Part 82, Subpart F)

under section 608 of CAA.

Sound Pressure levels are tested in an anechoic chamber under ISO Standard 3745.

All communication cable to be minimum 18 AWG, 2-conductor, twisted, stranded, shielded

and must comply with applicable local and national codes. Ensure the communication

cable is properly grounded at the master outdoor unit only. Do not ground the ODU-IDU

communication cable at any other point.
