Aprilaire 800 Steam Humidifier Overview
The Aprilaire Model 800 is a canister steam humidifier designed to deliver humidity in the form of steam. It uses an HVAC system duct or an optional fan pack for distribution to the conditioned space.
Model 800 Functionality
The Aprilaire 800 steam humidifier operates by generating steam, which is then dispersed into the living space through the home’s ductwork or an optional Aprilaire fan pack. This process ensures that the humidity is delivered effectively. The model uses a canister system to produce steam, and it is designed to work in conjunction with the HVAC system to provide whole-house humidification. The steam is released into the air stream of the heating system, effectively increasing moisture levels during dry periods. It is important to ensure proper installation for efficient and safe operation;
Installation Prerequisites
Prior to installation, it’s crucial to understand that qualified HVAC and electrical contractors must perform the work. Compliance with local, state, and federal regulations is also mandatory.
Qualified Installer Requirement
The installation of the Aprilaire 800 steam humidifier mandates the expertise of qualified HVAC and electrical professionals. This requirement ensures that the system is installed correctly and safely. These professionals possess the knowledge and skills necessary to handle the complexities of the installation process, including the electrical connections and integration with the existing HVAC system. This also ensures proper setup and adherence to safety regulations for optimal performance and longevity of the unit.
Compliance with Regulations
Adherence to all local, state, and federal regulations is absolutely essential during the installation of the Aprilaire 800 steam humidifier. This ensures that the installation is not only safe but also legal. Installers must be well-versed in the relevant codes and standards to maintain compliance. This includes adhering to guidelines related to electrical work, plumbing, and the overall integration of the humidifier with the existing building systems to ensure safety and proper function of the system.
Location and Placement

ADMC Installation Location
The Aprilaire ADMC, or Advanced Digital Manual Control, must be installed within the conditioned living space. This ensures accurate readings and proper functionality of the humidifier system. Refer to the “Determine Location For Control” section of the ADMC installation manual for specific guidelines. Proper placement is crucial for effective humidity control throughout the home, and should be carefully considered before proceeding with the installation. The chosen location should also be accessible for future maintenance and adjustments.
Dispersion Tube Mounting
The dispersion tube for the Aprilaire 800 steam humidifier must be mounted with its plate positioned vertically. This orientation is critical for proper steam distribution and optimal performance of the humidification system. Incorrect mounting can lead to issues with steam absorption and may affect the overall efficiency of the unit. It is essential to adhere to this vertical mounting requirement to ensure the system functions as intended, providing consistent humidity levels throughout the space.
Wiring and Electrical
The Aprilaire 800 requires specific wiring, including a blower activation relay, part number 4851. Consult the installation instructions for detailed wiring diagrams to ensure proper connections and safe operation.
Blower Activation Relay
The Aprilaire 800 steam humidifier often requires a blower activation relay, specifically part number 4851. This relay is crucial for proper functionality, ensuring that the HVAC system’s blower operates when the humidifier is active. This ensures that the steam generated by the unit is properly distributed throughout the conditioned space, providing consistent humidity levels. Correct installation of this relay is vital for optimal performance and preventing operational issues. Refer to the appropriate wiring diagrams in the installation manual for proper connection details.
Wiring Diagrams
The installation of the Aprilaire 800 steam humidifier necessitates careful attention to the provided wiring diagrams. These diagrams, found within the installation instructions, detail the correct connections for the transformer, circuit board, and other components using 18 AWG wire. Proper adherence to these diagrams is crucial to ensure safe and effective operation of the humidifier. Incorrect wiring can result in malfunctions or damage. Always consult the specific manual for accurate wiring instructions before installation begins.
Initial Setup
During the first heating season, the humidifier control requires initial settings. This ensures proper operation of the Aprilaire 800. Refer to the manual for specific instructions.
First Heating Season Settings
During the initial heating season, it’s crucial to configure your Aprilaire humidifier control correctly. These initial settings are essential for proper operation and to ensure the humidifier effectively maintains the desired humidity level within your home. Consult the provided installation manual for specific instructions on setting up the control during the first heating season, as these settings might differ from ongoing operational parameters. This step is vital to the humidifier’s performance and longevity.
Operation and Maintenance
Regular maintenance of the Aprilaire 800 includes replacing the steam canister. This ensures the humidifier continues to operate efficiently. Consult the manual for specific replacement instructions.
Steam Canister Replacement
The Aprilaire 800 steam humidifier requires periodic replacement of its steam canister to maintain optimal performance. Genuine Aprilaire replacement model 80 steam canisters are available through your installing contractor, or from most heating and air conditioning contractors. It’s crucial to follow the manufacturer’s guidelines provided in the installation and maintenance manual for the correct procedure. The canister replacement process will ensure the system continues to deliver humidity effectively and prevent any operational issues. Always ensure the unit is powered off before initiating any maintenance.
Control Systems
The Aprilaire 800 utilizes a control system, which can include a thermostat with integrated humidifier control or a separate humidifier control. These systems may operate in manual mode.
Humidifier Control Installation
The Aprilaire Humidifier Control is typically installed within the cold air return duct. During the initial heating season, specific settings need to be configured on the control. For detailed installation instructions, it is important to consult the provided installation manual. Proper setup of the control ensures accurate humidity management throughout the home, and facilitates efficient operation of the Aprilaire 800.
Manual Mode Operation
When the Aprilaire 800 is operating in manual mode, the homeowner assumes responsibility for making adjustments as needed. This requires the homeowner to monitor and adjust the humidifier settings directly. Using manual mode means that the system will not automatically adjust to changing conditions, and requires consistent user interaction to maintain desired humidity levels, following the guidelines in the installation manual for proper usage.
Duct Humidity Sensor Placement
The duct humidity sensor must be placed in the supply duct, at least six inches from any fresh air intake, and twelve inches from any moisture source, per the manual.
Sensor Location Guidelines
When installing the duct humidity sensor, ensure it is positioned in the supply duct for accurate readings. Maintain a minimum distance of six inches upstream from any fresh air intake ducts to avoid inaccurate measurements due to outside air influence. Furthermore, position the sensor at least twelve inches upstream from any potential moisture sources within the ductwork. This placement helps prevent false readings caused by localized humidity and ensures the sensor provides a reliable measure of the overall duct humidity for optimal humidifier performance.
