Congratulations on purchasing a new Sentinel Dehumidifier. Your new dehumidifier comes with an extended 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 liability reverts to the owner and the warranty are 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 the 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 12″ clearance and the discharge requires a minimum of 36″ clearance.
The best option for proper diffusion of air throughout the room is to have the discharge blowing away from a wall and the inlet pulling air in parallel to a wall.
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 the unit, unplug from power, then use a damp cloth to wipe the 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.

p p l y

Power Supply: 115 V, 60 Hz AC, Single Phase
Outlet Requirement: 3-Prong,
GFI 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 the unit into a 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 setpoint, the dehumidifier will energize. Air is drawn across an evaporator coil, which is cooler than the dew point of the 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.

I n s t a ll a t i o n

The area to be controlled should be sealed with a vapor barrier. If the 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 the barrier is completely dry and area is thoroughly ventilated before installing a dehumidifier.

S t e p #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”.

S t e p #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 the drain line, remove the compression nut and slide it over the end of the hose to be attached to the unit. Slide compression nut side of the hose over the insert on the compression fitting completely. Tighten compression nut.

S t e p #3: Plug unit into 15 amp grounded circuit.

Key Functions

Power Key
♦ Use this button to turn the dehumidifier on and off. Press once to turn the machine on. You will hear 2 beeps and the light will illuminate green. Press the power button a second time and you will hear one beeps the machine shuts down. Note that there is a one-minute fan delay on the shutdown.
Arrow Buttons
Use the up and down arrow button to set the desired humidity setpoint on the display screen.
The setpoint can be any number between35-90%. Creating a setpoint means that when the indoor humidity is lower than the setpoint, the machine will stop automatically. Conversely, when the indoor humidity is higher than the set level, the unit will operate. NOTE: The humidity levels displayed are approximate only (+/- 5%)
Continuous Mode
♦ To switch into the continuous mode, simply use the down arrow to set the humidity below35%. The Cont. light should illuminate green on the display board to indicate that you have successfully switched into continuous mode. The display screen will show “CO”.
♦ When set to continuous, the dehumidifier will run constantly, regardless of the humidity level. To stop the machine, turn the unit off or switch back to normal humidistat operation. If you would like to switch back to normal humidistat operation, simply move the setpoint above35%.
Central Control
♦ This mode is not applicable on the Sentinel HDi65.
♦ Central Control light should off at all times when not connected to the AC.
Manual Drain Button
♦ For extended storage or movement of the machine, press the “Drain” button to remove water from the integral pump’s reservoir.
Auxillary Terminals A5/A6
♦ The A5/A6 on the terminal strip can be used as a water level warning switch for external condensate pumps.
♦ If an external pump is connected, the pump must have a self-contained power supply and a water level signal line.

Humidity Display Screen
• The display screen has two functions:
1. When the unit is powered on, it shows the humidity of the space.
2. 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.
Power Indicator Light
• This light indicates that the unit is properly powered on and ready to operate. Always make sure the unit is “off’ prior to performing any service.
Continuous Mode/AutoDefrost Light
• When this light illuminates green, it indicates that the dehumidifier is set to the continuous operation mode.
• When the light glows red, it means the unit is in auto defrost mode and clearing the evaporator coil of any ice buildup.
Co m p r ess o r Light
♦ When the compressor light glows red, it indicates the compressor has been initiated but is currently warming up.
♦ Once the compressor light switches to green, it indicates the compressor is in working status.

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 that 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 Matainence 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 at 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 19.6 ft
It can be allowed to pump water automatically when it reaches a certain water level, or it can be pumped manually at any time, 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 four screws on the water pump panel, you can see the fixed state of the water pump.
Use a Phillips screwdriver to loosen the four screws of the water pump fixing bracke
Pull out the hose fixed in the water storage box, and take out the water pump for replacement
Install the new water pump to its original position according to the above steps.
