The MRCOOL Olympus concealed ducted mini-split air handler hides above a ceiling or in a soffit and delivers air through ductwork to one or more grilles. It comes in 9,000 to 24,000 BTU sizes, handles 0 to 0.4 in. w.c. of external static pressure (up to 0.8 on the 24,000 BTU size), and pairs with an Olympus E Star condenser of the same capacity or an Olympus Multi-Zone condenser.
It suits rooms where no head should be visible. Installation is by a licensed HVAC contractor.
Features
Out of Sight
The metal cabinet installs in a ceiling or soffit and only the supply and return grilles show in the room.
Adjustable Static Pressure
Four static pressure settings cover 0 to 0.4 in. w.c. on the 9,000 to 18,000 BTU sizes and 0 to 0.8 in. w.c. on the 24,000.
Wired and Wireless Control
A hard-wired wall controller comes with the unit, along with a handheld remote.
Built-In Condensate Pump
An internal pump handles condensate where a gravity drain is not practical.
Quiet Operation
Sound ranges from 23 dBA on the 9,000 BTU silent setting to 40 dBA at turbo on the largest sizes.
Leak Detection
An A2L refrigerant sensor watches for R-454B leaks and shows an error code if one is found.

About MRCOOL
MRCOOL designs heating, cooling and water-heating equipment from its home base in Hickory, Kentucky. The range runs from DIY ductless mini-splits, built around MRCOOL's patented pre-charged Quick Connect line sets, through contractor-installed mini-splits, central split systems, packaged units and gas furnaces, to HeatWise water heaters and CoolBlade HVLS fans for warehouses and shops.
Olympus Multi-Zone is MRCOOL's contractor-installed ductless heat pump for several rooms on one outdoor unit: four R-454B condensers from 18,000 BTU (up to three zones) to 48,000 BTU (up to six zones), each serving a mix of Olympus wall-mount air handlers, four-way ceiling cassettes and concealed ducted air handlers in 9,000 to 24,000 BTU sizes. The same indoor heads pair one-to-one with the Olympus E Star single-zone condensers.
