Fig. 6—Suggested Rigging

Lifting point should be directly over the center of gravity for the unit.

Step 6—Connect Condensate Drain

NOTE: When installing condensate drain connection be sure to comply with local codes and restrictions.

Models 50GS and 50GX dispose of condensate water through a 3/4 in. NPT fitting which exits through the base on the evaporator coil access side. See Fig. 2 & 3 for location.

Condensate water can be drained directly onto the roof in rooftop installations (where permitted) or onto a gravel apron in ground- level installations. Install a field-supplied condensate trap at end of condensate connection to ensure proper drainage. Make sure that the outlet of the trap is at least 1 in. lower than the drainpan condensate connection to prevent the pan from overflowing (See Fig. 7). When using a gravel apron, make sure it slopes away from the unit.

Connect a drain tube using a minimum of 3/4 -in. PVC or 3/4 -in. copper pipe (all field-supplied) at the outlet end of the 2-in. trap.

Do not undersize the tube. Pitch the drain tube downward at a slope of at least 1-in. for every 10 ft. of horizontal run. Be sure to check the drain tube for leaks. Prime trap at the beginning of the cooling season start-up.

Step 7—Install Duct Connections

The unit has duct flanges on the supply- and return-air openings on the side and bottom of the unit. For downshot applications the ductwork can be connected to the roof curb. See Fig. 2 & 3 for connection sizes and locations.

IMPORTANT: Use flexible connectors between ductwork and unit to prevent transmission of vibration. Use suitable gaskets to ensure weathertight and airtight seal. When electric heat is installed, use fire proof canvas (or similar heat resistant material) connector between ductwork and unit discharge connection. If flexible duct is used, insert a sheet metal sleeve inside duct. Heat resistant duct connector (or sheet metal sleeve) must extend 24-in. from the unit discharge connection flange into the ductwork.

50GX, 50GS specifications

Carrier has long been a leader in the HVAC industry, and its latest offerings, the 50GX and 50GS series, continue this tradition. These units stand out for their robust design, advanced technology, and energy-efficient operation, making them ideal choices for commercial and light industrial applications.

The Carrier 50GX is a packaged rooftop unit known for its innovative features aimed at enhancing energy efficiency while ensuring optimal indoor air quality. It employs a variable-speed compressor, which allows for precise temperature control and reduced energy consumption. The 50GX is equipped with microprocessor controls that optimize performance and simplify maintenance, offering real-time diagnostics and monitoring.

One of the standout technologies in the 50GX is its use of R-410A refrigerant, a greener alternative that reduces environmental impact without compromising cooling performance. This refrigerant is designed to deliver superior cooling efficiency while meeting strict environmental regulations. Additionally, the system features an integrated economizer, which takes advantage of outside air to improve energy efficiency during cooler months, reducing reliance on mechanical cooling.

The 50GS series, while similar in many respects to the 50GX, is tailored for applications requiring heating solutions. These units offer gas heat as an option, providing flexibility for varying climate conditions. The 50GS also incorporates an advanced heat exchanger design that maximizes heat transfer efficiency and reduces operational costs.

Both the 50GX and 50GS units are built with durability in mind. They feature a galvanized steel cabinet with a powder-coated finish, providing resistance to rust and corrosion. The robust construction ensures a long lifespan even in challenging environments.

Maintenance is made easier with these models, thanks to their accessible design that allows for quick servicing. Both the 50GX and 50GS units come with a host of customizable options, including different airflow configurations and additional filtration systems to enhance air quality.

In conclusion, the Carrier 50GX and 50GS series represent the pinnacle of HVAC technology with their focus on energy efficiency, environmental sustainability, and robust construction. These units are ideal for customers looking to invest in reliable and efficient climate control solutions for their facilities, combining advanced technology with time-tested engineering.
