3.Apply torque in one-third steps until required torque is reached. Load all bolts to each one-third step before pro- ceeding to next one-third step.

4.No less than one hour later, retighten all bolts to required torque values.

5.After refrigerant is restored to system, check for refriger- ant leaks with soap solution or Halide device.

6.Replace cooler insulation.

Condenser Coils

COIL CLEANING — For standard aluminum, copper and pre-coated aluminum fin coils, clean the coils with a vacuum cleaner, fresh water, compressed air, or a bristle brush (not wire). Units installed in corrosive environments should have coil cleaning as part of a planned maintenance schedule. In this type of application, all accumulations of dirt should be cleaned off the coil.

Do not use high-pressure water or air to clean coils — fin damage may result.

CLEANING E-COATED COILS — Follow the outlined pro- cedure below for proper care, cleaning and maintenance of E-coated aluminum or copper fin coils:

Coil Maintenance and Cleaning Recommendations — Rou- tine cleaning of coil surfaces is essential to maintain proper operation of the unit. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend the life of the unit.

Remove Surface Loaded Fibers — Surface loaded fibers or dirt should be removed with a vacuum cleaner. If a vacuum

cleaner is not available, a soft brush may be used. In either case, the tool should be applied in the direction of the fins. Coil surfaces can be easily damaged (fin edges bent over) if the tool is applied across the fins.

NOTE: Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers and dirt into the coil. This will make cleaning efforts more difficult. Surface loaded fibers must be completely removed prior to using low velocity clean water rinse.

Periodic Clean Water Rinse — A periodic clean water rinse is very beneficial for coils that are applied in coastal or industrial environments. However, it is very important that the water rinse is made with very low velocity water stream to avoid damaging the fin edges. Monthly cleaning as described below is recommended.

Routine Cleaning of Coil Surfaces — Monthly cleaning with Enviro-Shield™ Coil cleaner is essential to extend the life of coils. It is recommended that all coils, including standard aluminum, pre-coated, copper/copper or E-coated coils are cleaned with the Enviro-ShieldCoil Cleaner as described below. Coil cleaning should be part of the units regularly scheduled maintenance procedures to ensure long life of the coil. Failure to clean the coils may result in reduced durability in the environment.

Enviro-ShieldCoil Cleaner is non-flammable, hypoaller- genic, non-bacterial, USDA accepted biodegradable and 100% ecologically safe agent that will not harm the coil or surround- ing components such as electrical wiring, painted metal surfac- es or insulation. Use of non-recommended coil cleaners is strongly discouraged since coil and unit durability could be affected.

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.
