How to use Sentinel HD55S Dehumidifier

If you want to optimize the efficiency of the sentinel HD55S Dehumidifier, you need to do the following:

· Place the dehumidifier on a dry level surface. Avoid putting it on a vapor barrier such as a damp basement.
· Consult the manual when installing the unit
· When you want to switch the unit on or off, make use of the remote control.
· Avoid using the power switch to switch it off.
· Use the arrow keys to set your desired humidity level. Choose anything between 50- 55%.
· Even after the unit has been switched off via the remote control, ensure that you allow the fan to continue running until it stops. It helps to remove the dissipated heat.
· The unit drains itself automatically as it operates. However, if you are planning to keep it in-store, you must give an allowance of at least 10 minutes so that it can defrost. You should lean the drain a little bit to ensure that the unit drains completely.  

When you want to store the unit, the following must be observed.

· Turn off the dehumidifier and allow it to dry
· The power code should be wrapped and secured
· The filter mesh should be protected by covering it
· Ensure the unit is stored in a clean dry place

 

Where It Can Be Used Application

The unit finds a lot of applications in warehouses, basement, crawl spaces, and even offices. It is also used in shops, storage areas, apartments, and factories. Other places where the unit is likely to be used are in bars and restaurants and museums. It is also widely used in computer rooms to reduce dampness or dust. Sentinel HD 55 is an energy-efficient product that is, CE, ETL.

It is a whole-house dehumidifier that can be relied on to solve damage to any building. If a building suffers from dampness, Sentinel HD55S can be deployed to provide a solution to the humidity problem. The dehumidifier comes with a filter that makes installing it much easier.  The fact that it features optional duct mounting flanges reduces the time it takes to have it installed.

 

How the Unit Operates

You will select the relative humidity you want. It uses the integral humidistat to monitor the space and conditions. When the humidity level rises beyond the set levels, the unit energizes. When this happens, it draws air across the evaporator coils. Typically, the coils will be cooler than the dew point of the air. Moisture will then condense out of the air.  The remaining air will then be reheated and distributed into the condenser coil. It will then be redistributed in the house.

 

Installing The Unit

Ensure that you use vapor barriers to seal off the areas where you want to control their humidity levels. If it is the crawl spaces, check and ensure that all the vents are sealed.

Also, ensure that the environment in which you want to install the dehumidifier is not corrosive. Notice that we have some liquid barriers that dry through solvent evaporation. So it is your mandate to ensure that the barrier is dry and that the area is sealed.

Before using the dehumidifier, check and ensure that it is placed on a level surface.  Avoid placing it in a vapor barrier.

Set the desired humidity level using the up and down button.  Choose the most comfortable level for you. It should range from 36-90%. Once you set your point, the machine will stop dehumidifying as long as the set point has been reached. When indoor humidity rises above the set level, the machine automatically starts operating.

You can choose to set the machine into continuous mode. This can be done by using the up and down arrow. Check and ensure you see the continuous button illuminate green. It indicates that the unit has been switched to a continuous mode. You will see CO on the display screen.

 

Cleaning the unit

To optimize the use of the dehumidifier, it is necessary that you clean its body.  You need is a soft piece of cloth to do this. Soak it in water without soap or solvent and use it to wipe the dehumidifier. Also, you may unplug and clean the filter by washing it with soap-less water. Alternatively, you may choose to vacuum the unit.  Just try to ensure that it dries before reinstalling it.  Notice that the coil must also be cleaned once a year. You may use an approved coil cleaner to do this job.

 

Precautions

· Before powering the sentinel dehumidifier, ensure that it is connected using a grounded electrical connection.
· When you choose to have the unit repaired or maintained, ensure that you get a competent technician.
· If you choose to move the dehumidifier to another place, unplug it from the power supply.
· If the unit gets flooded with water, it is recommended that you open it so that it can dry before attempting to reconnect it.
· Don't position the discharge and the inlet onto the wall. Ensure that the inlet has a 12" space clearance while the discharge should have a 36" clearance.
· If the unit is close to a wall, ensure that the inlet is parallel to the wall while the discharge should face away from the wall.
· If you choose to clean the unit, ensure that it is unplugged from the power source.
· Don't use the machine as a support when you want to reach items that are high.

Love this unit. It is extremely powerful and effective. Also, Alorair has the best customer service. After a couple years, the blower motor was making some loud noises. The helped me diagnose the issue and sent replacement parts with detailed videos on how to fix it. All super easy, quick and covered by the warranty. Great experience!

Keeping the humidity down very well in my crawl space. Need a separate pump, but I like that.

I like this ALORAIRE dehumidifier. Mounted on a small level precast concrete pad. Very easy to handle, as it is not a huge unit. Used a separate float activated pump, available from Amazon. The combination has been keeping the humidity down in my crawl space, to prevent mold and musty odors.
Defective begin and noisy end

Upon installing it, it did not power on at the beginning. I have checked the breakers on the electric panel and everything is working correctly. But finally I make it work after tech support for troubleshoot some issue on the machine. However, it is a little too noisy when the machine is on. My tenants complain about the noise pollution and not comfortable when the machine is on. That is what I just experienced.

Encapsulated crawl space

From the Amazon

By 'Amazon Customer', Reviewed on June 02, 2023
After going through 3 big box dehumidifiers in 7 years my last two only lasted 3 years. I selected this unit because of design and the warranty. After a week with no dehumidifier, my crawl space humidity was reading 62% rh when I installed this unit and set it for 48%. The encapsulated space is 2000 sq ft averaging about 3 1/2 to 4 feet high or 7-8000 cf. The humidity is monitored by a separate remote unit, in 6 hours it dropped to 51%, and checking the next morning to 46%. The performance is excellent, quiet, easy to install, my only problem was a failure on the leveling feet but was easily corrected. If you are connecting your drain tube to a 5/8" fitting soak the tube end in very hot water for about a minute to fit the tubing on the fitting.

The humidity in my gravel bottom crawl space was registering 80%+. I set this humidifier in the crawl space with the water tube going into the sump pump. I set the humidity level at 55% and it brought down to that level in about a week and has maintained it at that level ever since. The unit is also very quiet.
