Connecting Up and Removing Air In the Circuit

Connecting Up and Removing Air In the Circuit

The outdoor units is loaded with sufficient R-22 refrigerant for 5 m(16 25 ft) of piping. The air in the indoor unit and in the pipe must be purged. If air remains in the refrigeration pipes, it will affect the compressor, reduce to cooling capacity and could lead to a malfunction. Refrigerant for air purging is not charged in the outdoor unit. Use Vacuum Pump as shown at the figure.

Adding Refrigerant

Refrigerant must be added if the piping measures more than 5 m(16 25 ft) in length (maximum of “A” m/ft). The quantity of additional refrigerant is variable according to the installation situation. Thus, make sure the outdoor unit situation before adding refrigerant. This operation can only be performed by a qualified refrigeration specialist.

1Connect each assembly pipe to the appropriate valve on the outdoor unit and tighten the flare nut.

2Referring to the illustration opposite, tighten the flare nut on section B first manually and then with a wrench, applying the following torque.

3Connect the charging hose of low pressure side of manifold gauge to the

packed valve having a service port as shown at the figure.

4 Open the valve of the low pressure side of manifold gauge counter clockwise.

5Purge the air from the system using vacuum pump for about 10 minutes.

◆ Close the valve of the low pressure side of manifold gauge clockwise.
◆ Make sure that pressure gauge show -0.1MPa(-76cmHg) after about
10 minutes. This procedure is very important in order to avoid gas leak.
◆ Turn off the vacuum pump.	Vacuum
◆ Remove the hose of the low pressure side of manifold gauge	pump
maintaining a vacuum.

6	Set valve cork of both liquid side and gas side of packed valve to the	A(gas)
	open position.	B(liquid)
7	Mount the valve stem nuts and the service port cap to the valve, and
	tighten them at the torque of 183kgf•cm(13ft•lb) with a torque wrench.
8	Check for gas leakage.
	◆ At this time, especially check for gas leakage from the 3-way valve’s
	stem nuts(A port), and from the service port cap.	3-way valve

ACC2400C, ACC2800C, UCC2400C, UCC2800C specifications

Samsung has consistently been at the forefront of innovation in the electronics industry, and its ACC and UCC series of air conditioners—namely the ACC2800C, ACC2400C, UCC2400C, and UCC2800C—stand as a testament to this commitment. These models are designed to provide exceptional comfort and efficiency for both residential and commercial applications.

The ACC2800C and ACC2400C models are known for their powerful cooling capabilities. The ACC2800C features a robust performance with a cooling capacity of up to 28,000 BTUs, making it ideal for larger spaces. In contrast, the ACC2400C, with a cooling capacity of 24,000 BTUs, is tailored for medium-sized rooms, striking a balance between power and efficiency.

In terms of technology, both models incorporate advanced inverter technology which allows for more precise temperature control, optimizing energy consumption. This means that users can enjoy a cooler environment without worrying about soaring energy bills. Additionally, the units are equipped with an intelligent air flow system that ensures even distribution of cool air throughout the space, enhancing comfort levels across the board.

On the other hand, the UCC2400C and UCC2800C models are recognized for their unique features tailored towards enhancing user convenience. These units come with a state-of-the-art smart control system, which can be managed via smartphones—allowing users to adjust temperatures and settings remotely. This feature is particularly beneficial for those who want to prepare their spaces in advance before arriving home.

The UCC series also includes air purification technology, which helps eliminate allergens and pollutants, promoting a healthier indoor environment. Furthermore, the addition of a self-cleaning function in both models helps maintain optimal performance and efficiency.

Key characteristics of these air conditioner models include whisper-quiet operation, ensuring indoor comfort isn’t disrupted by loud machinery. This is particularly advantageous during night-time use. Moreover, the sleek and modern design of the units allows them to blend seamlessly into any decor, appearing as a stylish addition rather than an eyesore.

Overall, the Samsung ACC2800C, ACC2400C, UCC2400C, and UCC2800C represent a convergence of efficiency, technology, and comfort. With their powerful cooling capabilities, advanced features, and user-oriented designs, they cater to a wide range of needs, ensuring that consumers can enjoy a comfortable environment throughout the year.
