This unit can maintain optimal humidity in homes or workplaces. 

The adverse effects of high humidity or moisture content in the air are quite severe, especially to non-prepared structures and individuals. Excessive humidity can wreak havoc on a home or a workplace. It will make the air feel heavy and stale. It will lead to the growth of mildew and molds.

Why wait until a health problem creeps up before you tackle the issue?

Crawlspaces or basements tend to have increased humidity levels. This is mainly because these spaces are either partially or completely underground. Once the moist air comes into these spaces, the moisture condenses on the walls or floor. This causes increased dampness.

Increased dampness creates the perfect environment for increased dust mites and the growth of mold and mildew. According to the American lung association, these are known allergens that can cause respiratory problems and asthma.

The AlorAir Sentinel HDi90 Duct-able Version Basement/Crawl Space Dehumidifier works to get rid of the moisture content in the air. It ensures that your home is free from excess moisture, helping you breathe healthy air.

Sentinel HDi90 is a duct-able dehumidifier with a built-in humidistat and push-button port for remote control of the dehumidifier from anywhere in the building or using an optional wireless remote sensor. The remote sensor can be placed up to 150 feet away from the unit. When used in conjunction with the optional wireless remote humidistat, humidistat readings can be displayed on an LCD screen on the front of the unit.

Safety Precautions When Using Sentinel HDi90 Duct-able Version Basement/Crawl Space Dehumidifier

•    For your own safety, ensure that the unit is connected using a grounded electrical connection.

•    Ensure that maintenance and repair is only done by qualified and competent technicians

•    The dehumidifier should only be powered when it is sitting upright on a leveled ground. Don’t operate it in any other orientation since it will allow the water to flood the components and could lead to an accident.

•    If you are moving the unit to another location, ensure that it is plucked off the power.

•    If you notice that the unit was flooded with water at some point, allow it to dry first before you reconnect or start it.

•    The inlet and the discharge should never be positioned on the wall. There should be at least 12’’ clearance between the unit’s inlet and an obstacle. Also, ensure that the clearance between the discharge and any obstacle is 36’’.

•    Let the discharge blow away from the wall while the inlet should be parallel to the wall.

•    No fingers should be inserted in the object's inlet.

•    When working on the unit, ensure that it is in an off position

•    The exterior surface should never be cleaned with water. Just use a damp cloth to wipe its exterior.

•    Do not step on the machine when you want to reach a certain height.
