Crawl Space Dehumidifiers

1. First, you will need to remove the control board access panel (on the duct side of the machine). To do this, simply use the screw driver or drill to remove the four screws on the panel.

2. At this point, you will need to unplug the following wires on the control board: (starting in the upper left corner and moving clockwise around the board)
• Compressor (Black)

• Power (White)

• Fan (Blue & Brown)

• Hot Gas Bypass Valve (Black)

• Pump (Black & White)

• Pump ( Red with White Cap)

• Pump (Red with Blue Cap)

• Coil Sensor (White)

• RH Sensor (Red)

• Display (White)

• Data Port (Black &Red)

• Dry Contacts/Terminal Strip (White & Blue)

• Power Cord (Black)

• Compressor (Brown & Blue)

3. Once the wires are unplugged, you can lift the the control board out of the machine. To do this, you will need to use the needle nose pliers. Use the pliers to push in the 4 “arrowhead” tabs (one in each corner). Simply squeeze each tab with the pliers so the control board can be lifted over the tab.

4. Now you’re ready to set the old control board aside and insert the new one. Carefully set the replacement control board in place, ensuring the tabs secure into place.

5. Next, reinsert the wires into the control board. It’s helpful to go in the reverse order removal: (starting at the bottom left corner and moving counterclockwise)
• Compressor (Brown & Blue)

• Power Cord (Black)

• Dry Contacts/Terminal Strip (White & Blue)

• Data Port (Black &Red)

• Display (White)

• RH Sensor (Red)

• Coil Sensor (White)

• Pump (Red with Blue Cap)

• Pump (Red with White Cap)

• Pump (Black & White)

• Hot Gas Bypass Valve (Black)

• Fan (Blue & Brown)

• Power (White)

• Compressor (Black)

6. Once all the wires are plugged in, all that is left is to replace the easy access panel. Set the panel in place, then replace the screws.

1. First, you will need to remove the easy access panel so you have access to the pump. To do this, use the screwdriver or drill to remove the 4 screws holding the panel in place.

2. After that you will need to disconnect the drain tube from the pump. Simply press in the button at the drain tube connection and lift the drain tube away from the pump.

3. Once the drain tube is disconnected, you can use the cutters to cut the zip tie holding it to the pump.

4. Now you will need to use the screwdriver to remove the screw holding the pump to the base.

5. Now you’re ready to lift the pump off the base. Gently place your screwdriver in the notch on the side of the pump and lift it off the base.

6. As you remove the pump, you will notice that it is connected by three wires- black with white cap, white with red cap, and white with white cap. Unplug all three then set old pump aside.

7. Keep in mind that the pump base will stay in the dehumidifier- you’re only switching the pump. At this point, wipe out any dirt or water thats in the base with paper towels.

8. Now you’re ready to install the new pump. Start by reconnecting the wires you unplugged in Step #6.

9. Next, set the new pump on the base, being careful not to tangle the wires in the process. Use the screwdriver to insert the screw.

10. Once the pump is screwed in, you can reattach the drain hose.

11. Finally, close up the access panel by replacing the four screws.

1. First, mix your cleaning solution using one of the options listed above.

2. Next, you will need to open the drain side end cap so you have access to the drain tray. To do this, use the screwdriver or drill to remove the screws (one on each side of the end cap).
NOTE: If you have moved your dehumidifier out of the crawl space, make sure the drain line has somewhere to drain, prior to proceeding to the next step.

3. Once the end cap is open, press the drain button on the display to drain the reservoir. Disconnect power to the dehumidifier.

4. Next, slowly pour the cleaning solution into the drain train. Continue pouring all of the cleaning solution, moving from side to side to evenly distribute it.

5. Let the cleaning solution soak for 10-15 minutes. Reconnect the dehumidifier to power.

6. Pour the clean water into the drain tray, until you hear the pump activate twice (normally 16-32 ounces)

7. Finally, close up the end cap, and secure the two screws (one on each side).

1. First, you will need to open the end cap so you have access to the display board. To do this, use the screwdriver or drill to remove the screws (one on each side of the end cap).

2.Gently open the end cap.

3. Next, unplug the display wire from the display board.

4. At this point, use the screwdriver or drill to remove the 4 screws holding the display board in place (one screw in each corner).

5. After the screws are removed, lift the display board away from the cabinet.

6. Now set the new display board in place, and secure with the 4 screws.

7. Once the display board is secure, plug in the display cable.

8. Finally, close the cabinet door, then secure both sides.

1. First, you will need to open the end cap so you have access to the display board. To do this, use the screwdriver or drill to remove the screws (one on each side of the end cap).

2.Gently open the end cap so you have access to the sensor.

3. Once the end cap is open, you will need to remove the sensor cover. Use the screw driver or drill to remove the four screws (one in each corner).

4. Lift the sensor cover off and slide the cover down so you have access to the sensor.

5. Unplug the sensor from the sensor (RH) cable. Set the sensor aside.

6. Grab the new sensor and plug it into the sensor cable.

7. Slide the sensor cover down the sensor wire and position the cover and sensor in place on the cabinet. Secure the sensor by replacing the 4 screws.

8. Finally, close the end cap and replace the screws (one on each side).

1. First, you will need to open the end cap so you have access to the drain tray (the coils are being the end cap without the display board). To do this, use the screwdriver or drill to remove the screws (one on each side of the end cap).

2.Carefully open the end cap so you have access to the coils.

3. Next, evenly spray the coils using the coil cleaner.

4. That’s all you have to do. There’s no need to rinse the coils because when you start using the unit again, the dehumidification process will do that for you.

5. Repeat this process once a year.

1. First, mix your cleaning solution using one of the options listed above.

2.Next, you will need to open the end cap so you have access to the gravity drain. To do this, use the screwdriver or drill to remove the screws (one on each side of the end cap).
NOTE: If you have moved your dehumidifier out of the crawl space, make sure the drain line has somewhere to drain, prior to proceeding to the next step.

3. Once the end cap is open, slowly pour the cleaning solution into the drain train. Continue pouring all of the cleaning solution, moving from side to side to evenly distribute it.

4. Let the cleaning solution soak for 10-15 minutes.

5. After the cleaning solution has soaked, pour in the clean water to flush out the drain line. Move from side to side to evenly distribute, just as you did with the cleaning solution.

6. Finally, close up the end cap, and secure the two screws (one on each side).
