Designed for both residential and light commercial applications, this slim ducted solution provides dependable comfort while maintaining a clean, unobtrusive interior appearance.

Powerful & Efficient Performance

The PEFY-L06NMSU-A delivers 6,000 BTU/H of nominal cooling capacity and 6,700 BTU/H of nominal heating capacity, making it an ideal choice for small rooms, offices, and tightly zoned areas requiring precise temperature control.

Built with a high-efficiency DC fan motor (96W), the unit supports multiple airflow stages of 176, 212, and 247 CFM, allowing it to adjust output based on comfort needs and duct design requirements.

Low Static Ducted Comfort with Flexible Air Distribution

Designed for low external static pressure applications, the PEFY-L06NMSU-A supports adjustable static pressure settings of 0.02, 0.06, 0.14, and 0.20 in. WG. This flexibility makes it well-suited for short duct runs, multi-room distribution, or concealed airflow delivery through supply grilles.

Its horizontal-ducted configuration allows installers to hide the unit above ceilings while maintaining even, controlled air distribution throughout the conditioned space.

Ultra-Quiet Operation for Sound-Sensitive Spaces

Operating as quietly as 22 dB(A), the PEFY-L06NMSU-A is an excellent option for bedrooms, study areas, healthcare settings, or offices where low noise levels are essential.

Even at higher fan speeds, sound output remains minimal (up to 28 dB(A)), ensuring comfort without disruption.

Compact, Ceiling-Ready Design

With a slim cabinet height of only 7-7/8", this indoor unit is specifically engineered for low-clearance ceiling installations. Its compact dimensions measure:

• 31-1/8" W × 27-9/16" D × 7-7/8" H

• Weight: only 42 lbs

This lightweight, space-saving design makes it ideal for retrofit projects, tight mechanical spaces, and modern construction where minimal visual impact is desired.

Built-In Condensate Management

The PEFY-L06NMSU-A includes an integrated condensate lift pump capable of lifting condensate up to 21-11/16", simplifying drain routing and improving installation versatility.

A 1-1/4" O.D. drain connection ensures reliable condensate removal for both gravity and pumped drainage applications.

Smart Controls & System Integration

This unit supports a wide range of advanced control options, including:

• Wired MA controllers

• RedLINK® wireless remote systems

• Third-party thermostat interfaces

• Building automation compatibility via BACnet® or Modbus® (with adapters)

• kumo cloud® Comfort App connectivity through optional wireless interfaces

These control capabilities allow the PEFY-L06NMSU-A to integrate seamlessly into both single-zone and multi-zone Mitsubishi Electric ductless systems.

Reliable Refrigerant & Electrical Configuration

The PEFY-L06NMSU-A is designed for modern R454B refrigerant systems and connects via:

• 1/4" liquid line

• 1/2" gas line

Electrical requirements include 208/230V, single-phase, 60 Hz operation, with an MCA of 0.79 and MOCP of 15 amps for safe and dependable performance.

Engineered for Hidden, Zoned Comfort

Purpose-built for concealed ceiling installations, the Mitsubishi PEFY-L06NMSU-A offers an ideal combination of compact sizing, whisper-quiet operation, and ducted airflow flexibility.

Perfect for small zones and precision comfort applications, this low static horizontal-ducted unit delivers efficient, reliable, and unobtrusive climate control in spaces where aesthetics and performance matter most.
