J Electromagnetic noise enters into TV sets or radios

Is the unit grounded?

Yes

Is the distance between the antennas and the indoor unit within 9.91 ft., or is the distance between the antennas and the outdoor unit within 9.91 ft.?

Is the distance between the TV sets or radios and the indoor unit within 3.28 ft., or is the distance between the TV sets or radios and the outdoor unit within 9.91 ft.?

Yes

Ground the unit.

Extend the distance between the antennas and the indoor unit, and/or the antennas and the

outdoor unit.

Extend the distance between the TV sets and/or radios and the indoor unit, or the TV sets or

radios and the outdoor unit.

Are the antennas damaged? Is the coaxial cable damaged?

Is there any poor contact in the anten- Yes na wiring?

No
Is the indoor/outdoor connecting wire of
the air conditioner and the wiring of the	Yes
antennas close?	Yes
No

Replace or repair the antenna.

Replace or repair the coaxial cable.

Extend the distance between the indoor/outdoor connecting wire of the air conditioner and the wir-

ing of the antennas.

Even if all of the above conditions are fulﬁlled, the electromagnetic noise may enter, depending on the electric ﬁeld strength or the installation condition (combination of speciﬁc conditions such as antennas or wiring).

Check the followings before asking for service.

1.Devices affected by the electromagnetic noise TV sets, radios (FM/AM broadcast, shortwave)

2.Channel, frequency, broadcast station affected by the electromagnetic noise

3.Channel, frequency, broadcast station unaffected by the electromagnetic noise

4.Layout of ;

indoor/outdoor unit of the air conditioner, indoor/outdoor wiring, grounding wire, antennas, wiring from antennas, receiver

5.Electric ﬁeld intensity of the broadcast station affected by the electromagnetic noise

6.Presence or absence of ampliﬁer such as booster

7.Operation condition of air conditioner when the electromagnetic noise enters in

1)Turn OFF the power supply once, and then turn ON the power supply. In this situation, check for the electromagnetic noise.

2)Within 3 minutes after turning ON the power supply, press OPERATE/STOP (ON/OFF) button on the remote controller for power ON, and check for the electromagnetic noise.

3)After a short time (3 minutes later after turning ON), the outdoor unit starts running. During operation, check for the elec- tromagnetic noise.

4)Press OPERATE/STOP (ON/OFF) button on the remote controller for power OFF, when the outdoor unit stops but the indoor/outdoor communication still runs on. In this situation, check for the electromagnetic noise.

MUY-D36NA, MUZ-D30NA, U1, MUY-D30NA, MUZ-D36NA specifications

Mitsubishi Electronics has long been at the forefront of innovation in heating and cooling solutions, and its latest lineup of multi-zone air conditioning units—MUZ-D36NA, MUY-D30NA, U1, MUZ-D30NA, and MUY-D36NA—reflects this commitment to quality and efficiency. Designed for both residential and commercial applications, these units offer advanced features that enhance comfort and energy savings.

One of the standout characteristics of these models is their energy efficiency. Each unit is equipped with high SEER (Seasonal Energy Efficiency Ratio) ratings, making them ideal for users looking to reduce energy consumption while maintaining optimal indoor climates. The efficiency is complemented by inverter technology, which allows the compressor to adjust its speed based on the cooling demand. This results in a smoother operation, reduced noise levels, and significant energy savings over time.

These units also feature advanced filtration systems that improve indoor air quality. The included high-performance air filters capture dust, allergens, and other particles, ensuring that occupants breathe cleaner air. Additionally, some models are equipped with a plasma filtration system that actively neutralizes odors and airborne contaminants, making them particularly suitable for allergy sufferers.

Mitsubishi's advanced climate control technologies set these models apart. The system can be easily controlled using a user-friendly remote or via a mobile app, offering convenience and flexibility. The intelligent temperature control ensures that rooms are heated or cooled consistently, regardless of external conditions.

Installation versatility is another highlight. These units can be configured for multi-zone systems, allowing for tailored comfort in different spaces. The compact and sleek design makes them suitable for various installations, whether in homes, offices, or retail environments.

Furthermore, the MUZ-D and MUY-D series are equipped with quiet operation features, ensuring minimal disruption in both residential and commercial settings. This is particularly beneficial in spaces where noise could be a concern, such as bedrooms or conference rooms.

In summary, Mitsubishi's MUZ-D36NA, MUY-D30NA, U1, MUZ-D30NA, and MUY-D36NA offer a powerful combination of energy efficiency, advanced filtration, intelligent controls, and quiet operation. These features make them an excellent choice for anyone looking to enhance indoor comfort while minimizing environmental impact. Whether it's for a single room or an entire building, these units are engineered to deliver reliable performance year-round.
