Step-by-Step Installation Guide

Mount the humidifier on the supply or return plenum. Connect the bypass duct and install the water supply and drain lines. Finally, configure the humidifier control.

Mounting the Humidifier

The Aprilaire Model 600 humidifier can be mounted on either the supply or return plenum of a forced air handling system. Ensure the unit is level and secure. Use the provided hardware to attach it firmly to the plenum. The humidifier is reversible, allowing installation with right or left-hand bypass duct connections. Position it to ensure proper airflow and serviceability. The built-in bypass damper simplifies installation. Mounting near the furnace is recommended for optimal performance. Always follow the installation template and safety guidelines provided in the manual.

Connecting the Bypass Duct

Connect the bypass duct to either the supply or return plenum, ensuring proper alignment and a secure fit. The Aprilaire Model 600 is reversible, allowing installation with right or left-hand bypass duct connections. Attach the bypass duct to the humidifier’s outlet, ensuring it is sealed tightly to prevent air leaks. Use the built-in bypass damper to regulate airflow. Verify that the duct is properly insulated and routed to maintain efficient system performance. Test the connection for leaks before finalizing the installation.

Installing the Water Supply and Drain

Connect the water supply line to the solenoid valve, ensuring it is securely attached. Install the saddle valve on the water supply line and connect it to the humidifier. For the drain, attach the PVC drain line to the humidifier’s drain outlet and route it to a nearby floor drain or condensate pump. Ensure the drain line is properly sloped to prevent water pooling. Test the water supply and drain connections for leaks before completing the installation. Annual maintenance, such as replacing the water panel, is crucial for optimal performance.

Post-Installation Setup

After installation, configure the humidifier control to desired settings. Set the humidity level and test the system to ensure proper operation. Follow manufacturer guidelines for optimal performance.

Configuring the Humidifier Control

Configure the Aprilaire Model 600 humidifier control by selecting either Automatic or Manual mode. In Automatic mode, the control is installed in the cold air return duct and adjusts humidity based on outdoor temperatures. Manual mode allows you to set a fixed humidity level, requiring adjustments as outdoor temperatures change. Ensure the control is properly connected to your HVAC system and set the desired humidity level. Use the Test/Reset function to verify operation and reset the water panel timer. Always follow the manufacturer’s guidelines for optimal performance and to avoid condensation issues.

Testing the System

After installation, test the Aprilaire Model 600 by running the HVAC system and checking for proper water flow and humidistat operation. Use the Test/Reset feature to ensure the humidifier activates and stops correctly. Verify there are no leaks in the water supply, drain, or bypass duct connections.
