The PQSH1200 Drain Pan Heater for Multi F Systems easily installs into your Multi F / Multi F Max outdoor unit. By installing the Drain Pan Heater, you can extend the cooling range of your CHV or HV unit from 14°F down to -4°F. It can also prevent ice build-up that may come from extreme winter weather.
Compatible outdoor units include Multi F and Multi F Max Outdoor units (LMU18-36CHV and LMU480-600HV units), and Single Zone 18,000+ BTU LUU***HV units (18, 24, 36, 42, and 48K) using cassette and high static duct indoor units.
This is a great option for computer rooms or other temperature sensitive rooms where cooling is needed year round.
