Do not use solvents or cleaners on or near the display or circuit board. 2. Unplug the dehumidifier before servicing. Sudden operation may cause personal injury or property damage. PRINCIPLE OF OPERATION Your Aprilaire® Whole-Home Dehumidifier installs as part of your home’s central heating and cooling system, removing excess moisture and reducing the damage that mold and mildew can have on the sustainability of your home and the health of your family. The Model 75 digital control constantly monitors and displays the relative humidity of the air in your home and controls it to the level you set, putting you in control of your comfort. OPERATING INSTRUCTIONS DEHUMIDIFIER Begin by plugging in the dehumidifier and turning the On/Off switch ON. CONTROL The control will allow you to set the desired relative humidity (%RH) level in your home and can be used to turn dehumidification On or Off. Begin by pressing the ON button and ON will be displayed on the LCD Screen (see LCD display in Figure 1). Use the arrow buttons to set the control at 59% when first installed. Allow the dehumidifier to run until the initial setpoint has been reached, before deciding if you want to change the humidity setting. Raise the setting if you prefer the air to be less dry; this will reduce the amount of time that the dehumidifier runs. Lower the setting if you prefer the air to be more dry; this will increase the amount of time that the dehumidifier runs. Your comfort is the best measure of how to adjust your setting. When first installed, your dehumidifier has to remove all the moisture that is initially in your home. The 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 FIGURE 1 – Control Display and User Buttons LCD Display Mode Buttons – Use to turn control On/Off.

As a result, it is not uncommon for the dehumidifier to operate for an extended period of time when first installed. Energy Savings Tip #1: Adjust the setting to be as high as is comfortable to reduce dehumidifier run time – if it feels clammy or smells damp or moldy lower the setting. To save energy, turn the dehumidifier control OFF when you open your windows just as you would with air conditioning. Energy Savings Tip #2: If vacating your home for an extended period in the summer, set the RH at 59% and set your thermostat to as high as you are comfortable setting it in the cooling mode. Consult with appropriate professionals regarding the highest temperature that is safe for your pets or possessions. This will keep the humidity at a controlled level to help prevent mold while minimizing the amount of cooling energy used.

See Control Limits, page 3. 90-1636 TURNING CONTROL ON/OFF • Pressing the ON button will turn on the control. • Pressing the OFF button will turn off the control. • The control will continue to display the measured humidity when OFF. • The humidity setting cannot be changed when the control is OFF. FIGURE 3 – ON/OFF Buttons CHANGING THE HUMIDITy SETTING • The first press of either the or button will display the humidity setting on the LCD. • Each subsequent push of the up or down buttons will change the setting by 1%. • If a button is held down, the setting will continually change by 1% every 1/2 second for as long as the button is pressed. • The control will exit the humidity setting screen 5 seconds after the last button press/release. FIGURE 4 – UP/DOWN Buttons FIGURE 5 – Humidity Setting Screen 90-1637 HOW DOES THE CONTROL WORK? • When the measured humidity is greater than the setting, the control will turn on the dehumidifier and ON will blink on the LCD display. • When the measured humidity falls 3% below the setting, the control will turn off the dehumidifier and ON will stop blinking, but remain displayed on the LCD. CONTROL LIMITS The control limits are used to make sure the dehumidifier does not run when conditions are outside of the operating limits. Dehumidifiers are not as effective when conditions are outside of the operating limits. For example, the dehumidifier will not remove much moisture when conditions are cool and dry. Control limits allow the dehumidifier to work efficiently within the operating range and turn off when conditions are outside of these limits. • Dew Point Lower Limit: 40°F • Temperature High Limit: 99°F SEQUENCE OF OPERATION • The dehumidifier will turn off if one of the control limits has been exceeded. • If the control measures a dew point below 40°F OR a temperature above 99°F, the control will deact...
