Warranty Registration

Congratulations on purchasing a new Sentinel Dehumidifier. Your new dehumidifier comes with an extensive warranty plan. To register, simply fill out and return the warranty form provided in the dehumidifier box.
Be sure to note your dehumidifier serial number as you will need it for registration.

Safety Notes

The Sentinel Series Dehumidifier must always be connected using a grounded electrical connection (as required for all electrical appliances). If non-grounded wiring is used, all I iability reverts to owner and the warranty is voided.
Sentinel Dehumidifiers should only be maintained and repaired by a qualified technician.
Sentinel Dehumidifiers are only intended for operation when oriented with the unit sitting on its feet and level. Operating the unit in any other orientation could allow water to flood electrical components.
Always unplug dehumidifier before moving.
If there is a chance that water flooded the dehumidifier, it should be opened and allowed to dry thoroughly before reconnecting to electrical power and restarting.
To ensure proper operation, neither the inlet nor discharge should be positioned against a wall. The inlet requires a minimum of 6′ clearance and the discharge requires a minimum of 6′ clearance.
For better use of the dehumidifier, both air inlet and air outlet should be facing the open area of the space.
Do not insert your fingers or any object into the inlet or discharge.
All work on the dehumidifier should be done with the unit “off’ and unplugged.
Do not use water to clean the exterior of the machine. To clean unit, unplug from power, then use a damp cloth to wipe exterior.
Do not stand on the machine or use it as a device to hang clothes.

Identification

For future reference, write down the model, serial number, and date of purchase for your dehumidifier.
This is extremely helpful if you need to seek assistance in the future. The data label on the side of your unit has the key characteristics of your specific machine.

Electrical Supply

Power Supply: 115 V, 60 Hz AC, Single Phase
Outlet Requirement: 3-Prong, GFCI
Circuit Protector: 15 Amp
WARNING 240 Volts AC may cause serious injury from electric shock.
To reduce risk of injury:

Disconnect electrical power before servicing .
Only plug unit into grounded electrical circuit.
Do not use an extension cord.
Do not use a plug adapter.

Principle of Operation

The Sentinel Series Dehumidifier utilizes its integral humidistat to monitor the conditioned space.
When the relative humidity goes above the selected set point, the dehumidifier will energize. Air is drawn across an evaporator coil, which is cooler than the dew point of air. This means moisture will condense out of the air. The air is then reheated through the condenser coil and distributed back into the room.

Installation

The area to be controlled should be sealed with a vapor barrier. If unit is installed in a crawlspace, all vents should be sealed.
WARNING Do not install your dehumidifier in a corrosive environment. Some liquid vapor barriers dry via “solvent evaporation”. Always make sure that barrier is completely dry and area is thoroughly ventilated before installing dehumidifier.

Step #1: Place dehumidifier on a level surface.
Do not place directly on vapor barrier. For example, use blocks, or pavers to create a level surface. If the unit is handled in such a manner that the compressor did not remain in the upright position, you will need to place it on a level surface, then wait a minimum of 2 hours before turning “on”.

Step #2: Set Up Drain Line.
The included drain line attaches to unit via a compression type fitting on the discharge end of the unit. To attach drain line, remove the compression nut and slide it over the end of the hose to be attached to unit. Slide compression nut side of hose over the insert on the compression fitting completely. Tighten compression nut.

Step #3: Plug unit into 15 amp grounded circuit.

Key Functions

The “ON / OFF” Button
Press this button to turn ON/OFF the dehumidifier.
When the dehumidifier is turned off, there would be a 120 seconds delay on the fan. Do not unplug the unit until the fan is off.
“SET” Button
This button is used to change the humidity setpoint from 25% to 80%. The dehumidifier may also be set at “CO” or Continuous Operation mode to run the dehumidifier continuously. The setpoint has 5% increments of each press.
The dehumidifier will automatically turn on/off when the Relative Humidity Percentage(%) is 3% – 5% higher/lower than the setpoint.
“Drain” Button
Hold this button down for at least 3 seconds to switch the drain system to use. Either pump drain system or gravity drain system.
Water Pump Drainage Mode
If the “Pump” light is turned ON, ii indicates that the pump drain system is in use.
The “Drain” button can be pressed once to force the water pump to remove the collected moisture from the water tray for 14 seconds. This button is not valid when the pump is draining.
If the water pump float switch detected a high level of water in the tray, the pump will automatically run and drain the collected moisture for 14 seconds. If a high level of water is still detected, after the pump runs for 14 seconds, the screen will display an “E4” error code, and the entire machine will be turned off.
Gravity Drainage Mode
If the “Pump” light is turned OFF, it indicates that the gravity drain system is in use.
The Water Tray Plug should be removed from the dehumidifier to properly use this drain system. This allows the dehumidifier to continuously drain the moisture collected.
If a high level of water is detected by the float switch for 14 seconds, the screen will display an “E4” error code and the dehumidifier will STOP from running to avoid a water leak.
Note: When moving the machine from one location to another, wait at least 10 minutes after turning off. This will allow the moisture in the coil to drip down in the water tray and you may tilt the dehumidifier in the direction of the drain hole to remove the collected moisture or water, completely.
“GPP” button
This button is used to change the humidity reading from RH% to GPP (Grains per pound).
GPP is the unit used to measure the weight of moisture in the air. The number of grains per pound of dry air expresses the specific humidity of the air. The GPP setpoint can be set at 25 to 200.
Relative humidity (RH) refers to the moisture content of the atmosphere, expressed as a percentage of the amount of moisture that can be retained by the atmosphere at a given temperature and pressure with condensation.
“SET +Drain” key
if you press the combination button “SET +Drain” for 3 seconds, the temperature of the room will be displayed in Celsius.
“SET +GPP” key
“SET+ GPP” key combination press for 3 seconds to display the temperature of the coil in Celsius.

Indicator Lights

Humidity Display Screen

The display screen has two functions:

When the unit is powered on, it shows the humidity of the space.
While setting the desired humidity level, the screen will show the set humidity. After a brief delay, the display will revert to current humidity level.

Remote Control Instructions

Sentinel Dehumidifiers can be controlled using an optional remote accessory.The Sentinel Remote Control connects to your Sentinel Series Dehumidifier via a 25′ CAT 5 cable. The remote control contains an integrated sensor which gives you multiple options for remotely controlling your unit, in addition to monitoring the conditions surrounding the dehumidifier. One application for the remote control is to install the dehumidifier in one room with the conditioned air ducted into a second room that contains the remote. For example, the dehumidifier could be installed in a laundry room and ducted into a living room. The remote would then be mounted in the living room so the remote sensor can control the humidity and provide easy controls for the user.
Another useful application for the remote control is if the dehumidifier is in area that’s difficult to access on a regular basis. For instance, if your dehumidifier is installed in your crawl space, the remote could be mounted in your living space or garage. This provides you with an easy way to monitor the dehumidifier.

Water Pump Maintenance and Application

Normal use of water pump

Determine whether the forced drainage function is useful
When the power is on, press the “Drain” button, the water pump runs normally, the pumping water is normal, there is no vibration and noise, and the water flows smoothly.
Determine whether the automatic drainage function of the water pump water level line is useful
Press the” ” button, the machine will perform dehumidification work. When the water level in the water collector reaches a certain height, the floating ball rises, and the water pump automatically enters the water pumping state, without vibration and noise, and the water flows smoothly.
Turn on the power and run the dehumidifier
If there is no abnormality in the forced drainage function and the automatic drainage function, the user can rest assured to use this equipment. If the water pumping is abnormal, the machine will display an error code of “E4”, at this time, the user can simply repair the pump failure by himself.
When the user is unable to repair, contact the manufacturer via email or phone.

Usage of gravity drainage pipe ( It can choose gravity drain or pump drain with the working environment ) .

For gravity drainage, the dehumidifier should be placed on a plane with a certain height. Pull out the screw tooth rubber plug at the outlet of the water collector of the dehumidifier, and plug in the water pipe.
The condensate dripping from the coil will be discharged along the water pipe, which can be collected into the water storage container or discharged out of the room (Note: the water pipe should not be higher than the dehumidifier and should be discharged towards the ground).

Water pump function

Solve the inconvenience that gravity drainage can only place the machine at a fixed height, it can be put in various places in the house for work.
The drainage pipe can be laid at will, without space restriction, up to 19.6ft.
It can be allowed to pump water automatically when it reaches a certain water level, or it can be pumped manually at anytime, which is more flexible and convenient.
The advantages of the water pump itself, low noise, low vibration, small size, long life, self-priming function, simple maintenance and easy replacement.
Use the rubber stopper plug the drain hole when you use the pump drain.

The fault judgment and maintenance method of the water pump

Problem judgment when “E4” error code appears:

The drainage hose is blocked or bent and deformed by foreign matter.
The drainage height exceeds the standard.
Water level switch failure.
Water pump failure or expiration of service life.
Internal water pump hose is blocked or bent and deformed by foreign matter.

Pump repair method

Use a Phillips screwdriver to unscrew the five screws on the water pump panel, you can see the fixed state of the water pump.
Use a Phillips screwdriver to loosen the two screws of the water pump fixing bracket.
Pull out the hose fixed in the water storage box, and take out the water pump for replacement.
