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.

Does the job

From the Amazon

Bought it for our crawlspace which is about 1200 ft.2 with a sand floor. It has taken care of all the moisture issues. Only thing I wished is it would come with two filters so you could clean one and let it dry and put the other one in and they really should send you two for the price you pay
Failed after about 8 months (*revised review*)

From the Amazon

By 'M. Schulte', Reviewed on February 22, 2023
Update 3-21: The company quickly contacted me and offered me a full refund. Once I received the shipping label, I sent the unit back and they refunded me the full amount. Given the cost of this unit, I really appreciated their offer. I will likely be purchasing this unit again as they clearly stand behind their product. Original review: Dehumidifier worked great for the first 8 months, but now it does not work. It trips the breaker when plugging it in, which appears to be a faulty motor or bad wiring inside the unit. Disappointing especially considering the cost of this unit.
Semi good.

First unit worked well. Refrigerant leak after a year. Paid to ship back. They sent me a replacement after I bought another shipping label. Super expensive to ship these things. New unit will not dehumidify to specified value. Unit just runs all day and never shuts off. Just not a very well engineered product. Gets old going into the crawl space to swap the units out. I will give a better review if they send me another unit. But they will have to reach out to me.. going to just buy a different brand this time. The company is in California so very expensive to ship. Not worth the hassle, you donot know if the unit is going to work or not. On to the next one.
Works fine. Arrived quite dented.

From the Amazon

By 'John Grover', Reviewed on February 19, 2023
Have the unit hanging in a basement, so I donot REALLY care how it looks. But the unit had quite a few dents in it which tells me it got some rough handling at some point. Filter was pushed inward, and the control panel sheet metal was pushed outward. I decided to just use it rather than return it, but if you care what it looks like be aware that there may be cosmetic problems.
Working so far... but costly to run.

This has helped pull my humidity down in my crawlspace. However, my unit runs 100% of the time. Costly to run. Canot find anyone to reinstall my gutter during the winter in Colorado. As soon as I can, I will resell it.
Great for crawl space

More expensive than the regular box store dehumidifier I used before but well worth the price. This is a Heavy duty work horse that self defrosts as well. Glad I decided to buy!
Works VERY well: Quiet, efficient, and definitely commercial grade

From the Amazon

By 'Richard Grove', Reviewed on January 09, 2023
This really is quite literally a commercial grade product. Quiet and very efficient. You WILL need to buy an external condensation sump(pump) to handle the water UNLESS you can drain it directly somewhere ... like a drain?!? I wish that a better "hanging" mounting option was available because you REALLY donot want this unit anywhere near rising water. I positioned mine between floor joists underneath my house after a minor flooding incident.
Great Dehumidifier and Customer Service!

My crawlspace humidity was consistently above 65% Rh and I have gone through at least 3 other brands(models) and none could bring it down to the 50% target I set on these units. This obviously would be a great environment for mold growth. I purchased the Alorair Sentinel HD55 last April after reading great reviews about the unit ability to remove humdity and the company 5yr warranty on their products. I installed the unit in my crawlspace and within 24 hours, it dropped the humidity from 65% down to the target Rh of 50% and has been able to keep my crawlspace consistently between 50-54% Rh since it was installed. Two weeks ago, the unit inexplicably stopped working and my humidity shot up to 75% over Christmas. I sent an email to support and they promptly wrote back and asked me to confirm a few details about the unit and issue as well as some photos of the unit. Sam and his support team from Alorair were able to determine it was due to a refrigerant leak and promptly issued a replacement. It is due to arrive Thursday and I will update this review. They stand behind their product and I will definitely purchase from them for my future dehumidification needs without question.
Versatile
By 'Alice', Reviewed on July 01, 2022
I am running an Alorair Sentinel HD55 dehumidifier unducted in my finished basement. The unit is solidly built, efficient, effective, and relatively quiet. Set at 48% relative humidity, it operates reliably with six-point hysteresis, turning on at 51% and turning off at 45%. The remote controller, purchased separately and located in still air about four feet from the HD55, is giving longer and more efficient duty cycles than I was getting with the onboard humidistat. With the HD55 level and its filter clean, I measure 65db at three feet. The sound is almost entirely that of rushing air. The compressor is audible, but at a significantly lower and less grating frequency than those of dehumidifiers from Frigidaire and Tosot that I tried earlier this year and found intolerable. Overall, I find the Alorair HD55 to be of higher quality, and to offer greater versatility than any other dehumidifier I have used.
Excellent!
By 'Michaelia', Reviewed on December 12, 2021
So far, the HD55 is doing an excellent job in conjunction with a Little Giant condensate pump to lift the discharge to an overhead pipe. The HD55 is quieter than my Frigidaire and does not freeze up (thanks to the HDV defrosting system), and I particularly like the easy access and disassemble modular all-metal construction. It is effortless to get at all the components if I need to repair them. The HD55 is expensive compared to most homeowner-priced units. Still, a bargain when you consider the cheaper plastic ones break down with regularity can be a real pain to take apart, and the cost of replacement parts makes them almost a waste of time to try and fix. I see lots of those in the scrap pile at our local town dump.

Hello, make sure the Sentinel HD55 dehumidifier is placed on a dry horizontal surface and avoid placing it on a wet surface. Besides, do not place the discharge port and entrance on the wall, make sure the entrance is parallel to the wall, and the discharge port should face away from the wall. Thanks for your question!
