Refrigerant Circuit

The refrigerant circuit is difficult to check for leaks without the prop- er equipment. If inadequate cooling is suspected, contact your local dealer for service.

!WARNING

EXPLOSION, BURN AND ENVIRONMENTAL HAZARD

Failure to follow this warning could result in personal injury, death or property damage.

System under pressure. Relieve pressure and recover all refrigerant before system repair or final unit disposal. Use all service ports and open all flow-control devices, including solenoid valves.

Unit Panels

After performing any maintenance or service on the unit, be sure all panels are fastened securely in place to prevent rain from entering unit cabinet and to prevent disruption of the correct unit airflow pat- tern.

Regular Dealer Maintenance

In addition to the type of routine maintenance you might be willing to perform, your unit should be inspected regularly by a properly trained service technician. An inspection (preferably each year, but at least every other year) should include the following:

1.Inspection and, if required, cleaning of the outdoor and indoor coils.

2.Inspection and, if required, cleaning of the indoor coil drain pan.

3.Inspection and cleaning of blower wheel housing and motor.

4.Inspection of all supply-air and return-air ducts for leaks, obstructions, and insulation integrity. Any problems found should be resolved at this time.

5.Inspection of the unit base to ensure that no cracks, gaps, etc., exist which may cause a hazardous condition.

6.Inspection of the unit casing for signs of deterioration.

7.Inspection of all electrical wiring and components to assure proper connection.

8.Inspection for leaks in the refrigerant circuit. Pressure check to determine appropriate refrigerant charge.

9.Inspection of compressor oil level by service person to ensure proper oil level is maintained in the compressor when it is installed and running.

10.Operational check of the unit to determine working conditions. Repair or adjustment should be made at this time.

Your servicing dealer may offer an economical service contract that covers seasonal inspections. Ask for further details.

Complete service instructions can be found in the unit Installation, Start-up and Service Instructions.

Before you call for service...

...check for several easily-solved problems.

If insufficient heating or cooling is suspected:

( ) Check for sufficient airflow. Check the air filter for dirt. Check for blocked return-air or supply-air grilles. Be sure they are open and unobstructed. If these checks do not reveal the cause, call your servicing dealer.

If your unit is not operating at all, check the following list for easy solutions:

( ) Check to be sure that the temperature specified by your User Interface is set below the indoor temperature during the cooling sea- son or above the indoor temperature during heating season. Be sure the User Interface is set to COOL or HEAT and not OFF.

( ) If your unit still fails to operate, call your servicing dealer for troubleshooting and repairs. Specify the model and serial numbers of your unit. (Record them in this manual in the space provided.) If the dealer knows exactly which unit you have, he may be able to offer suggestions over the phone, or save valuable time through knowledgeable preparation for the service call.

In Case of Trouble

If you perform the steps above and unit performance is still unsatis- factory, shut off the unit and call your dealer.

50GL-A specifications

The Carrier 50GL-A is a cutting-edge air conditioning unit that exemplifies excellence in climate control technology. This model, designed for both residential and commercial spaces, is equipped with an array of features that enhance comfort while ensuring energy efficiency.

One of the standout characteristics of the Carrier 50GL-A is its advanced inverter technology. This innovative feature allows the compressor to adjust its speed according to the cooling or heating demand, maintaining a consistent temperature with minimal fluctuation. By operating at variable speeds rather than a fixed rate, the unit effectively reduces energy consumption, resulting in lower electricity bills and a smaller carbon footprint.

The 50GL-A also boasts a high Seasonal Energy Efficiency Ratio (SEER) rating, indicating its capability to deliver significant energy savings over traditional models. This rating demonstrates the unit's efficiency in converting electricity into cooling power over a typical cooling season, which is a critical factor for environmentally conscious consumers and businesses.

A notable feature of the Carrier 50GL-A is its advanced filtration system. The unit is equipped with a high-efficiency air filter designed to capture a wide range of airborne particles, including dust, pollen, and other allergens. This filtration system not only contributes to improved indoor air quality but also prolongs the life of the unit by protecting the internal components from dust accumulation.

The design of the 50GL-A incorporates a quiet operation mode, ensuring minimal noise disruption. This is particularly advantageous for environments where a quiet atmosphere is essential, such as offices, libraries, and bedrooms. The unit's fan design and sound-dampening materials work in tandem to create a serene indoor environment.

In terms of installation and usability, the Carrier 50GL-A offers a user-friendly interface coupled with smart technology integration. Many models include Wi-Fi capability, allowing users to control their air conditioning system remotely via an app on their smartphones. This feature not only enhances convenience but also enables users to monitor and adjust settings while away from home or office.

Durability is another key aspect of the Carrier 50GL-A. Constructed with high-quality materials, the unit is designed to withstand various weather conditions. Its robust exterior helps prevent corrosion, ensuring the longevity of the air conditioning system.

In summary, the Carrier 50GL-A is a premium choice for efficient and reliable air conditioning. With its inverter technology, high SEER rating, advanced filtration, quiet operation, smart technology features, and durable design, it meets the diverse needs of modern households and businesses, all while promoting sustainable energy use.
