Key Features

• Superior Quality: Constructed with a robust 20x20 306 steel case, 12 aluminum fins per inch, and 3 rows of 3/8" seamless copper tubes for maximum efficiency. Edges and contact points are base brazed for high pressure and temperature resistance.
• Easy Installation & Practical Design: Installation is simplified with four thickened MNPT ports, allowing it to slide directly into the plenum without extra tools. Its compact design saves space without compromising performance.
• Highly Energy-saving: Converts thermal energy directly to a preset temperature, offering good heat transfer and refrigeration performance economically, without consuming electricity or oxygen.
• Wide Application: Provides high thermal efficiency and durability in a compact, lightweight construction, ideal for outdoor wood stoves, residential and commercial heating/cooling, forced air heating, hybrid systems, air conditioning, and dehumidification.

Important Notice

Copper pipes undergo a forging and water-cooling process during manufacturing, which may result in some water stains. These stains do not affect the normal use or performance of the heat exchanger. Please consider this before purchase.

Setup and Installation

The GPOAS Heat Exchanger is designed for straightforward installation. Follow these guidelines for proper setup:

1. Unpacking: Carefully remove the heat exchanger from its packaging. Inspect for any visible damage before proceeding.
2. Placement: Choose an installation location that provides adequate space for the unit and allows for proper airflow. The compact design helps optimize space utilization.
3. Connection: The heat exchanger features four thickened MNPT ports for simplified connection. Slide the unit securely into the plenum. No specialized tools are typically required for this step.
4. Piping: Connect the 1-inch copper ports to your hot water coil system. Ensure all connections are secure and leak-free to prevent system inefficiencies or damage.

Operating Instructions

The GPOAS Heat Exchanger is designed for efficient thermal energy conversion. To ensure optimal performance and longevity, follow these operating procedures:

1. Preheating (Steam Systems): If your system uses steam, it is crucial to preheat the heat exchanger with steam for approximately 10 minutes before starting the fan. This prevents sudden entry of cold steam into a cold heat exchanger, which could cause damage to the unit.
2. Automatic Temperature Control: The heat exchanger automatically heats water to a preset temperature during operation, contributing to energy efficiency and consistent performance.
3. Heating/Cooling Modes: The unit supports both heating and cooling functions. These modes can be switched as needed based on your system requirements and environmental conditions.
4. System Monitoring: Regularly monitor the system for consistent performance and any unusual sounds or indicators.

Maintenance

Regular maintenance ensures the longevity and efficient operation of your heat exchanger.

• Fins Cleaning: Periodically inspect the aluminum fins for dust, debris, or obstructions. Gently clean them using a soft brush or compressed air to maintain optimal heat transfer efficiency.
• Connection Check: Annually check all copper port connections for any signs of leaks or corrosion. Tighten connections as necessary to prevent pressure loss or damage.
• System Flush: Depending on your water quality and system usage, consider periodically flushing your heating system to prevent mineral buildup within the copper tubes. Consult a qualified HVAC professional for this procedure.
