About this Item

Mitsubishi M-Series Multi Zone Concealed Duct Heat Pump System, Bundle Includes - Outdoor Unit: MXZ-5B42NA, and Indoor Units: SEZ-KD12NA4R1.TH (x2), SEZ-KD15NA4R1.TH (x1)
  • Energy Star Estimated Cooling Cost: $765
  • SEER: 14.5

Product Highlights

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

System Includes

  • Outdoor Unit:   MXZ-5B42NA
  • Indoor Units:   SEZ-KD12NA4R1.TH (x2), SEZ-KD15NA4R1.TH (x1)
  • Required, but not included: 1/4" x 3/8" line set (x2) & 1/4" x 1/2" line set.   Linesets are available in various lengths from 15ft to 75ft.

This MR SLIM INVERTER-driven three-zone heat pump system, with concealed horizontal ducted indoor units, is ideal for conditioning rooms with limited wall space, because the evaporator stays hidden in the ceiling, floor, or closet.

Control Options
This system is compatible with the optional MHK1 wireless, RFI-RedLINK™ enabled, full-function wall mount controller, allowing homeowners to control their unit from a remote PC, smartphone or tablet (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 and linear expansion valve (LEV) 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 (19-35 decibels). According to a study performed by the National Institute for Occupational Safety and Health, most 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)
  • Ultra thin indoor unit body: 7-7/8" high
  • Built-in condensate removal mechanism with up to 21-11/16” lift
  • Long-life air filter is included with indoor units
  • Quiet outdoor operation ranging from 49-58 dB(A)
