Tube Plugging — A leaky tube can be plugged until retubing can be done. The number of tubes plugged determines how soon cooler must be retubed. Tubes plugged in the following locations will affect the performance of the unit: Any tube in the area, particularly the tube that thermistor T2 is adjacent to, will affect unit reliability and performance. Thermistor T2 is used in the freeze protection algorithm for the controller. If sev- eral tubes require plugging, check with your local Carrier rep- resentative to find out how number and location can affect unit capacity.

Figure 26 shows an Elliott tube plug and a cross-sectional view of a plug in place.

Use extreme care when installing plugs to prevent damage to the tube sheet section between the holes.

Retubing (See Table 31) — When retubing is to be done, ob- tain service of qualified personnel experienced in boiler main- tenance and repair. Most standard procedures can be followed when retubing the 10HB coolers. An 8% crush is recommend- ed when rolling replacement tubes into the tubesheet. An 8% crush can be achieved by setting the torque on the gun at 48 to 50 in.-lb (5.4 to 5.6 N-m).

The following Elliott Co. tube rolling tools are required:

B3400 Expander Assembly

B3401 Cage

B3405 Mandrel

B3408 Rolls

Place one drop of Loctite No. 675 or equivalent on top of tube prior to rolling. This material is intended to “wick” into the area of the tube that is not rolled into the tube sheet, and prevent fluid from accumulating between the tube and the tube sheet.

Tightening Cooler Head Bolts

Gasket Preparation — When reassembling cooler heads, always use new gaskets. Gaskets are neoprene-based and are brushed with a light film of compressor oil. Do not soak gasket or gasket deterioration will result. Use new gaskets within 30 minutes to prevent deterioration. Reassemble cooler nozzle end or plain end cover of the cooler with the gaskets. Torque all cooler bolts to the following specification and sequence:

5/8-in. Diameter Perimeter Bolts . . . . . . . . . . . . 150 to 170 ft-lb (201 to 228 N-m)

1/2-in. Diameter Flange Bolts . . . . . . . . . . . . . . . . 70 to 90 ft-lb (94 to 121 N-m)

1.Install all bolts finger tight.

2.Bolt tightening sequence is outlined in Fig. 27. Follow the numbering or lettering sequence so that pressure is evenly applied to gasket.

Air Conditioner specifications

Carrier Air Conditioners have long been synonymous with reliability and innovation in climate control. Founded by Willis Carrier, the inventor of modern air conditioning, the brand has continuously set industry standards through state-of-the-art technologies and features designed to enhance indoor comfort.

One of the standout features of Carrier air conditioners is their energy efficiency. Many models are equipped with advanced inverter technology, allowing the compressor to adjust its speed based on the cooling demand. This results in decreased energy consumption, which not only reduces utility bills but also lessens the environmental impact. Recognizing the importance of sustainable practices, Carrier has integrated eco-friendly refrigerants into their systems, further promoting energy-efficient operations.

Carrier also emphasizes user comfort through its variable speed systems. These systems maintain consistent temperatures while minimizing temperature fluctuations, ensuring an even distribution of cool air throughout the home. Additionally, many Carrier models come with advanced air filtration systems, designed to capture allergens, dust, and other particulates, thereby improving indoor air quality.

The smart technology featured in Carrier air conditioners plays a key role in modern convenience. Many units are compatible with smart home systems, allowing users to control settings remotely via smartphones or voice-activated devices. With features like programmable thermostats, users can easily set cooling schedules to match their lifestyle, ensuring comfort while maximizing energy savings.

Durability and noise reduction are also central to the Carrier brand. Many models are designed with sound-dampening features, making them some of the quietest units on the market. This is particularly advantageous for residential use, where noise can disrupt daily activities and sleep.

In terms of design, Carrier air conditioners come in various styles and capacities to suit a wide range of spaces, from compact apartment units to large central systems for sprawling homes. Their extensive warranty and service offerings further reinforce Carrier’s commitment to customer satisfaction.

In conclusion, Carrier air conditioners represent a perfect blend of cutting-edge technology, energy efficiency, and user comfort. Their emphasis on sustainability and smart features positions them as a leading choice for homeowners seeking reliable and innovative climate control solutions. Whether for cooling a small room or an entire house, Carrier remains a trusted name in air conditioning.
