Installation of Indoor Unit con’t

Connecting Indoor and Outdoor Electric Wires

(1)Open the front panel.

(2)Remove the wiring cover connect and fix power connection cord to the terminal board as shown in Fig 6.

(3)Make the power connection cord pass through the hole at the back of indoor unit.

(4)Reinstall the cord anchorage and wiring cover.

(5)Reinstall the front panel.

Note: AYX09NCJ and AYX12NCJ indoor units may be supplied with 3 pin power cable.

Note: All wires between indoor and outdoor units must be connected by a qualified electrical contractor.

●Electric wires must be connected correctly. Improper connection may cause malfunction.

●Tighten the terminal screws firmly.

●After tightening the screws, pull the wire slightly to confirm whether it's firm or not.

●Make sure that connections are earthed and grounded properly to prevent electric shock.

●Make sure that all wiring connections are secure and the cover plates are reinstalled properly. Poor installation may cause fire or electric shock.

The piping can be output from right, right rear, left or left rear.

(1)When routing the piping and wiring from the left or right side of indoor unit, cut off the tailings from the chassis when necessary (As shown in Fig.7).

(i)Cut off the tailings 1 when routing the wiring only;

(ii)Cut off the tailings 1 and tailings 2 when routing both the wiring and piping.

(2)Take out the piping from body case, wrap the piping, power cords, drain hose with the tape and then make them pass through the piping hole. (As shown in Fig.8)

(3)Hang the mounting slots of the indoor unit on the upper hooks of the mounting plate and check if it is firm enough. (As shown in Fig.9)

(4)The installation site should be 250cm or more above the floor.

Installation of Connection Pipe

(1)Align the centre of the piping flare with the related valve.

(2)Screw in the flare nut by hand and then tighten the nut with spanner and torque wrench by referring to the following:

Hex nut diameter	Tightening torque (N-m)
Ф 6	15～20
Ф 9.52	30～40
Ф 12	45～55
Ф 16	60～65
Ф 19	70～75

Note: Connect the connection pipe to indoor unit at first and then to

outdoor unit. Handle pipe bending with care. Do not damage the connection pipe. Ensure that the tapered nut is tightened firmly, otherwise, it may cause leakage.

AE-X12NCJ, AE-X28NCJ, AE-X09NCJ, AE-X18NCJ, AE-X24NCJ specifications

The Sharp AY-X12NCJ, AE-X18NCJ, AY-X28NCJ, and AY-X18NCJ, AE-X28NCJ models are remarkable air conditioning units designed to provide efficient cooling and heating solutions for various spaces. These units combine advanced technology and user-friendly features that cater to the needs of residential and commercial environments.

One of the standout features of these models is the incorporation of Plasmacluster Ion Technology, which helps to purify the air by generating positive and negative ions. This technology effectively eliminates bacteria, viruses, and allergens from the air, promoting a healthier indoor environment. The air purification feature is particularly beneficial for individuals with allergies or respiratory issues, as it continuously improves air quality.

Additionally, the Sharp AY-X and AE-X series is equipped with inverter technology, allowing for variable speed operation. This technology ensures that the compressor runs at different speeds tailored to the desired temperature setting, leading to significant energy savings. Inverter systems not only enhance energy efficiency but also provide a quieter operation, creating a more comfortable atmosphere without the disruptive noise often associated with traditional air conditioners.

Another notable characteristic is the modification of the cooling and heating modes. These units come with several modes that can be adjusted based on user preferences, such as turbo cooling for rapid temperature adjustment or sleep mode that gradually adjusts the temperature for optimal comfort during the night.

Moreover, the Sharp AY-X and AE-X series includes smart features such as remote control capabilities, allowing users to set and modify settings from a distance. This convenience is especially advantageous for busy individuals who want to come home to a pre-cooled or heated space without the hassle of manual adjustments.

Energy efficiency is further enhanced by the use of R32 refrigerant, which has a lower global warming potential compared to traditional refrigerants. This environmentally friendly refrigerant not only contributes to reducing energy consumption but also aligns with global initiatives to promote sustainability.

Overall, the Sharp AY-X12NCJ, AE-X18NCJ, AY-X28NCJ, AY-X18NCJ, and AE-X28NCJ models are designed for those seeking reliable, efficient, and advanced air conditioning solutions. With features that promote air quality, energy efficiency, and user convenience, these units stand out in the competitive market of HVAC systems.
