The Aprilaire dehumidifiers have a 5 year limited parts warranty from date of installation when installed by a licensed HVAC installer on all components including the compressor.
The warranty of our Aprilaire Dehumidifiers, model 1700,1710, 1710A, 1720,1730A, 1750, 1750A, 1770, 1770A, 1830, 1850, 1850F, and 1850W is a limited warranty on parts, 5 years from date of installation, when installed by a licensed HVAC installer.
These dehumidifiers (1830, 1850, 1850F, and 1850W include an onboard control which will automatically turn on the internal blower for 3 minutes each hour to sample the air and measure the moisture level of the incoming ambient air. This process determines if the relative humidity of the incoming air is above the set point (40%–80%). When the relative humidity in the home is above set-point, the dehumidifier will then energize its compressor and continue running until the set point is reached.
Your comfort is the best measure of where to set the humidity level. Maintaining humidity levels below 60% will help prevent mold growth. When first installed your Aprilaire dehumidifier has to remove all the moisture initially in your home. Your home acts like a sponge so the moisture in the materials of your home is at the same level as the air. After drying the air, the materials of the home will release moisture back into the air until they are again at the same level. As a result, it is not uncommon for the dehumidifier to operate for an extended time when first installed.
The air filter is a MERV 8.
Aprilaire dehumidifiers have a limited warranty on parts, 5 years from date of installation, when installed by a licensed HVAC installer. The length of the warranty does not indicate a shorter life. The environment, operating time and dehumidification level being maintained can have an effect on the life expectancy. Aprilaire dehumidifiers are extremely durable, including a 15+ year system life expectancy due to core design improvements as a direct result of continued extensive life-cycle testing, including application of vibrations, frequency harmonics, and forces up to 60g. In addition, Aprilaire dehumidifiers have undergone extensive coastal condition testing on electronics and controls.
Aprilaire dehumidifiers are extremely quiet and averages less than 55 dB (when ducted), which is quieter than a person-person conversation.
These dehumidifiers (1710A, 1750A, 1770A, 1830, 1850, 1850F, and 1850W) manufactured after January 1st 2012 offer the option of using our model 76 digital dehumidifier control to control the humidity level in the basement from any convenient area in your home. Your heating and cooling installer will know the proper wiring for this application.
Aprilaire dehumidifiers models 1750A, 1770A, 1830, 1850F, and 1850W offer zoned dehumidification through an internal control or external control. Your heating and cooling installer will know the proper wiring for this application.
The Aprilaire dehumidifier models 1710A, 1750A, 1770A 1830, 1850, 1850F, and 1850W can be controlled by a non Aprilaire control (Third-Party Control). The dehumidifier must have been installed after February 2011 and for the models 1710A, 1750A, 1770A have a control board with the local /external dip switch. Your heating and cooling installer will know if your thermostat (Third Party Control) can operate our Aprilaire dehumidifier and will be able to wire it accordingly.
The Model 1710A and 1750A dehumidifiers weigh 93lbs. The Model 1770A weighs 100 lbs. Our model 1730A weighs 65 lbs. The model 1830 weight is 67 lbs, 1850/1850F/1850W weigh 75 lbs.
All Aprilaire dehumidifiers are 110–120 VAC. The current draw of the 1730A is 7 amps. The 1710A and 1750A current draw is 8 Amps. The current draw of the 1770A is 14 Amps. The 1830 draws 6.3amps, the 1850/1850F/1850W draw 8 amps.
Aprilaire dehumidifiers are designed to control airborne moisture in areas where the ambient indoor temperatures are 65F-80F. If the ambient air temperatures are lower than 65F, there is less moisture in the air because colder air doesn’t hold as much moisture as warmer air. As a result our dehumidifier’s will remove less moisture at lower temperatures.
Dehumidifiers, including Aprilaire dehumidifiers are not designed to pull moisture off a surface. This includes windows, walls and floors. In order for any dehumidifier to attempt to remove moisture, the moisture needs to be in the air.
During the Summer time our Aprilaire dehumidifiers are designed to maintain an indoor relative humidity of 45% at an indoor ambient temperature of 75F( 52F dew point). Typical winter time conditions in a home are 70F indoor ambient temperature with a relative humidity of 35% (41F dew point). The lowest dew point Aprilaire dehumidifiers will attempt to achieve is 40F dew point. As a result our Aprilaire dehumidifiers usually will not operate in the winter time.
Moisture will form on windows anytime the surface temperature of the window is lower than the dew point temperature of the ambient air. For example indoor ambient conditions of 70F and, 40% Relative Humidity have a dew point temperature of 44F. When the outside temperature is 0F and the surface temperature of the glass at 43F, condensation will form on the windows because the glass surface temperature is below dew point temperature. In comparison, indoor ambient conditions of 70F and 30% Relative Humidity has a dew point temperature of 37F. When the outside temperature is 0F and the glass surface temperature is 43F no condensation will form on the windows because glass surface temperature is above the dew point temperature.
To remove moisture from windows during the winter time, a ventilation product is recommended.
These controls have been used with the models 1710A, 1750A and 1770A. All three of these Aprilaire controls can dehumidify the home based on the conditions in the area where the control is installed rather than using the on board control in the dehumidifier. The model 70 is a dew point control which dehumidifies the home based on the conditions in the area where the model 70 is installed. The model 75 and 76 are relative humidity controls which dehumidify the home based on the relative humidity in the area of the home where the controls are installed (external control). In addition, the model 76 control can be used to control the humidity level of the space where the dehumidifier is located from any convenient location within the living space (remote control).The model 76 displays the humidity level from the area where the dehumidifier is located by receiving the information from the on-board sensor in the dehumidifier. Your heating and cooling installer will know the proper control to use with your Aprilaire dehumidifier.
Our Aprilaire Dehumidifiers are not designed to work in pool applications, due to the corrosive nature of chemicals used in the pool. The chemicals used to treat the water can corrode the circuit boards inside the dehumidifier when the chemicals become airborne. There are dehumidifiers manufactured for use in a pool areas. One company you may consider contacting is Desert-Aire. Their phone number is (262) 946–7400.
The Aprilaire models ( 1830, 1850, 1850F, and 1850W include an onboard control which will automatically turn on the internal blower for 3 minutes at the end of each hour to sample the air and measure moisture level of the incoming ambient air. This process determines if the relative humidity of the incoming air is above the set point of the control dial, (40%–80%). When the relative humidity in the home is above set-point, the dehumidifier will then energize its compressor and continue running until the set point is reached.
