Product Highlights

IMPORTANT: This model requires remote controller MHK1 or PAR-32MAA-J, which must be purchased separately to complete the installation.

System Includes:

  • Outdoor Condenser Model: SUZ-KA09NA.TH
  • Indoor Ceiling Cassette Model: SLZ-KA09NAR1.TH
  • Decorative Discharge Grille: SLP-15AAUW
  • Required, but not included: 1/4" x 3/8" line set

This MR SLIM INVERTER-driven ceiling cassette ductless split system is ideal for conditioning bedrooms, home offices, living rooms, and dining rooms with limited wall space. These high efficiency heat pump systems offer a wide 4-way airflow pattern for maximum air distribution with an unimposing presence, and can be conveniently installed in a hard ceiling with an access panel or a 2" x 2" drop ceiling. Many of these 1:1 system configurations are Energy Star rated, and they have rated capacities ranging from 8,400-15,000 BTU, while operating at 15-16 SEER.

Control Options
The SUZ-K/SLZ-K models offer the optional wireless, RFI-RedLINK™ enabled, full-function wall mount controller, allowing homeowners to control their unit from a remote PC, smartphone or tablet (MHK1 sold separately). If you prefer a standard, fully wired and functioning wall mount control, this system also works with the PAR-32MAA-J (sold separately).

INVERTER Technology
The M-Series INVERTER-driven compressor works with the system's sophisticated electronic controls to detect temperature changes in a room or zone, automatically changing speeds to adjust for precise capacity and temperature control.

Quiet Operation
Mr. Slim Indoor Units operate at very low sounds levels (19-34 decibels). According to a study performed by the National Institute for Occupational Safety and Health, Mr. Slim Indoor Units are quieter than a human whisper (30 decibels) at low speed.

Environmentally Friendly
Mitsubishi was clearly taking the environment into consideration when designing the M-Series line by using R410A refrigerant with zero Ozone Depletion Potential (ODP), 83% recyclable components, and washable filters made from natural materials on all models.

Additional Features & Benefits

  • Auto fan speed feature plus three speed settings available (Low, Medium, High)
  • Contains Ventilation air knockouts
  • Condensate lift mechanism with up to 20" lift
  • Auto restart feature works after a power outage
  • Indoor unit is powered by the outdoor condenser

Please Note: Mini Split Systems must be installed by a licensed Contractor with an EPA Refrigerant Certification to qualify for warranty.

Which line set kit do I need?
This system uses (1) 1/4" x 3/8" line set. These are sold separately, and you can choose from our 15 ft, 25 ft, 35 ft, and 50 ft lengths. The length needed depends on the needs of your project and how you will set up the system (distance from outdoor condenser to indoor air handler).

Can I install this myself?
While installation of a ductless split is much easier than a central air system, it's still much more advanced than installing a window unit or portable. Furthermore, the manufacturer warranty is only valid if a licensed professional does the installation. So while it is possible to do the installation yourself, we strongly recommend you hire an HVAC professional in your area.

Is this backed by a warranty?
Yes, it comes fully backed by a manufacturer's warranty (click here for more details), and ComfortUp is an authorized online seller of these systems. Our Customer Care Team will provide assistance should you ever need to file a warranty claim with the manufacturer. Please be aware that only systems that are installed by a licensed HVAC contractor are backed by the warranty. Proof of licensed installation is required. The receipt/invoice from your contractor should be sufficient.
