3. How to Install the Indoor Unit

3-1. Preparation for Suspending

This unit uses a drain pump. Use a carpenter’s level to check that the unit is level.

3-2. Suspending the Indoor Unit

(1)Fix the suspension bolts securely in the ceiling using the method shown in the diagrams, by attaching them to the ceiling support structure, or by any other method that ensures that the unit will be securely and safely suspended. (Fig. 6-1)

(2)Follow the diagram to make the holes in the ceiling.

(3)Determine the pitch of the suspension bolts using the supplied full-scale installation diagram. The dia- gram shows the relationship between the positions of the suspension fitting, unit, and panel. (Fig. 6-2)

3-3. Placing the Unit Inside the Ceiling

(1)Be sure to remove the fan protection (4pcs) for transportation before hanging up the indoor unit.

(2)When placing the unit inside the ceiling, determine the pitch of the suspension bolts using the supplied full-scale installation diagram. (Fig. 6-3)

Tubing and wiring must be laid inside the ceiling when suspending the unit. If the ceiling is already constructed, lay the tubing and wiring into position for connection to the unit before placing the unit inside the ceiling.

(3)The length of suspension bolts must be appropriate for a distance between the bottom of the bolt and the bottom of the unit of more than 19/32" (15 mm) as shown in the diagram. (Fig. 6-3)

(4)Thread the 3 hexagonal nuts (locally purchased) and 2 supplied washers onto each of the 4 suspension bolts as shown in the diagram. Use 1 nut and 1 washer for the upper side, and 2 nuts and 1 washer for the lower side, so that the unit will not fall off the suspension lugs. (Fig. 6-4)

(5)Adjust so that the distance between the unit and the ceiling bottom is 1/2" (13 mm) to 23/32" (18 mm). Tighten the nuts on the upper side and lower side of the suspension lug. (Fig. 6-4)

CS-KS18B4UW & CZ-18BT1U, CS-KS12NB41 & CZ-18BT1U, CU-KS12NK1A, CU-KS18NKUA specifications

Panasonic has long been a reputable name in the HVAC (Heating, Ventilation, and Air Conditioning) industry, continuously innovating to provide efficient and sustainable solutions. Among their latest offerings, the CU-KS18NKUA, CS-KS18B4UW, CU-KS12NK1A, and CS-KS12NB41 split systems stand out for their advanced features and technologies designed to enhance user comfort while minimizing environmental impact.

The CU-KS18NKUA and CS-KS18B4UW units are high-capacity air conditioning systems that cater to larger spaces. One of their defining features is the inverter technology, which allows the compressor to adjust its speed according to the demand, leading to significant energy savings. The units operate quietly, contributing to a peaceful environment whether in homes or offices. Furthermore, the super-efficient energy consumption aligns with modern sustainability practices, reducing users' carbon footprints.

The advanced R32 refrigerant used in these systems is another highlight. R32 is known for its lower global warming potential compared to traditional refrigerants, making it an eco-friendly choice. These models are equipped with a powerful cooling capability while maintaining a compact and sleek design, seamlessly integrating into various interior styles.

In terms of indoor air quality, both models incorporate a multi-stage filtration system. This system effectively filters out dust, allergens, and harmful particles, ensuring cleaner indoor air. Additionally, the nanoe-G technology helps in deodorizing and purifying the air, enhancing the overall comfort and health of the environment.

The CU-KS12NK1A and CS-KS12NB41 models cater to smaller rooms but do not compromise on performance. They share similar inverter technology and energy-efficient characteristics as their larger counterparts, ensuring that users can enjoy a comfortable climate in a smaller footprint.

With an emphasis on user-friendly design, all these models come with intuitive remote controls, allowing for easy temperature adjustments and scheduling. Some units even offer Wi-Fi connectivity for remote access and monitoring via smartphone apps.
