MODEL 600 SERIES HUMIDIFIER

WARNING

1.ELECTRICAL SHOCK HAZARD.

CAUTION

RISK OF PROPERTY AND EQUIPMENT DAMAGE.

SPECIFICATIONS

HUMIDIFIER DIMENSIONS

Disconnect electrical power to the furnace before starting installation. Failure to do so could result in serious injury from electrical shock.

2.SHARP EDGES HAZARD. Sharp

edges may cause serious injury from cuts. Use care when making plenum openings and handling ductwork.

3.RISK OF SCALDING. Water

temperature over 125°F can cause severe burns and scald instantly. Shut off the hot water supply before disconnecting or tapping into any hot water supply line.

1.Do not install humidifier where freezing temperatures could occur. The water line could freeze and crack causing water damage to the home.

2.Do not install humidifier or bypass connection on the furnace jacket.

3.Do not install humidifier or bypass connection on a plenum face where the blanked off ends of the cooling coil will restrict air movement through the humidifier.

4.Do not set humidity level above recommended or to recommended level if condensation exists on inside windows of any unheated space, as condensation damage may result. Excess humidity can cause moisture accumulation which can allow the possibility for mold growth in the home.

5.Do not connect Model 600 or 600M transformer to blower motor wiring. Premature component failure may result.

6.When installing Humidifier Control on downflow furnace, ensure blower continues to run after a heat call is satisfied to eliminate high temperatures from damaging the Control.

7.Do not install humidifier where water pressure exceeds 125 psi, since damage to the humidifier may result. Follow codes in effect concerning pressure reduction.

8.Do not install humidifier on systems with greater than 0.4 in. wg pressure differential between supply and return plenums.

600M specifications

Aprilaire is a leading brand in the field of indoor air quality, and its series of humidifiers like the 600A, 700M, 400A, 500A, and 600M have been designed for optimal performance and user convenience. These humidifiers are engineered to maintain ideal moisture levels in your home, which is especially important during dry winter months.

The Aprilaire 600A is an advanced model equipped with automatic humidity control. This feature enables the humidifier to adjust moisture levels based on the outdoor temperature, ensuring a comfortable indoor environment throughout the changing seasons. The 600A is also easy to install and integrates seamlessly with your home’s HVAC system, supplying humidity throughout the entire house.

In contrast, the 700M is a manual humidifier option that offers flexibility in controlling humidity levels. This model is particularly suitable for homeowners who prefer a hands-on approach. The 700M can deliver up to 0.75 gallons of moisture per hour, making it effective for larger homes or spaces where humidity needs to be closely monitored.

The Aprilaire 400A and 500A models are geared towards versatility and space efficiency. The 400A, designed for homes with lower humidity requirements, operates quietly and offers a less invasive installation. It is suitable for areas up to 4,000 square feet, making it ideal for many average-sized homes. The 500A, on the other hand, is particularly designed for homes with a higher demand for moisture, providing consistent humidity control for larger spaces.

The Aprilaire 600M is another manual option that combines a straightforward user interface with robust performance. Similar to the 700M, it allows users to manually adjust humidity levels but features a slightly superior output rate.

One of the standout characteristics shared among these models is their ability to minimize the effects of dry air. By maintaining the right humidity levels, these humidifiers help reduce the likelihood of respiratory issues, dry skin, and static electricity, along with protecting wooden furniture and flooring from damage.

Overall, the selection of Aprilaire humidifiers offers something for every homeowner, from automated models that take the guesswork out of humidity control to manual options that provide a personal touch. Each model boasts its unique features while ensuring a healthier and more comfortable living environment year-round.
