Minimal Maintenance Required
The IW25 was built to run, so to make sure you get the most out of your dehumidifier, take time to perform regular maintenance. Although minimal effort is required, dehumidifier maintenance will keep your unit in good condition, extending the operating lifespan of your investment while helping to improve Indoor Air Quality (IAQ).
All air-treatment devices require a certain amount of scheduled maintenance. Regular maintenance of the IW25 In Wall/On Wall dehumidifiers is takes little time and keeps the systems in peak operating condition. Following recommended dehumidifier maintenance procedures can be combined with routine HVAC filter change to help keep your air cleaner.
What’s that blinking red light?
The IW25-4 is equipped with an LED filter maintenance reminder. When the light blinks red, it’s time to clean or change the air filter. If the filter is not changed within 14 days, the unit will automatically shut down to prevent system damage. At that point, you’ll need to access the controls behind the protective cover to reset the timer to a 60- or 75-day reminder and reset the “power” button to reactivate the system. Then proceed with regular maintenance below.
IW25-4 DEHUMIDIFIER MONTHLY MAINTENANCE REMINDERS:
1. Clean or change the reusable filter.
- Remove the front diffuser cover plate to snap the filter out of frame and reinsert a clean filter.
- OR, clean the filter, vacuum or wash with low pressure water. Shake the filter lightly to remove excess water.
- Reset the filter maintenance light. (See What is the Red Light on my Dehumidifier?)
- Keep clean filters on hand to help expedite the process.
2. Lightly wipe or vacuum the grill, humidity sensor, and coil fins.
- Check humidity sensor for dust and dirt. Wipe clean with damp cloth to remove debris.
- To clean coil fins, lightly vacuum or spray with a mild coil cleaner or all natural vinegar and water solution, sprayed directly on coils. No need to rinse foaming coil cleaner or vinegar solution.
3. Check the airways and drain hose to make sure they are unblocked.
- Check drain hose connects to “house drain” and water can flow continuously.
- Nothing should be directly in front of the grill as this could prevent proper air flow.
