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 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 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 the 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 the unit, unplug from the 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.

• E-mail: sales@alorair.com

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 the risk of injury:

1. Disconnect electrical power before servicing.
2. Only plug the unit into a grounded electrical circuit.
3. Do not use an extension cord.
4. 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 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.

Installation

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.

AWARNING:
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
the area is thoroughly ventilated before installing a dehumidifier.

Step #1: Place the dehumidifier on a level surface.
Do not place it directly on the 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 “it on”.

Step#2: Set Up the Drain Line.
The included drain line attaches to the 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 the compression nut side of the hose over the insert on the compression fitting completely. Tighten the compression nut.

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

Key Functions

1. Power Key
   

   • Use this button to turn the dehumidifier on and off. Press once to turn the machine on. You will hear 1 beep and the light will illuminate green. Press the power button a second time and you will hear one beep°as the machine shuts down. Note that there is a one-minute fan delay on shut -down.

2. Arrow Buttons

   • Use the button to set the desired humidity setpoint on the display screen.
     The set point can be any number between 25-80%. Creating a setpoint means that when the indoor humidity is lower than the set point, 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%)

3. Continuous Mode

   • When the set humidity is >80%, return the “CO” to continuous mode. When the indicator on the display board is green, it indicates that you have successfully switched to continuous mode. The display will show “CO”, 25%—>30%—>35% …… 75%—>80%—>CO—>25% …… power-off memory.
   • When set to continuous mode, the dehumidifier will no longer be affected by the temperature and will run continuously. To stop the machine, please turn off the unit or switch to normal humidity controller operation.

4. Water Pump Drainage

   • To extend the storage or movement of the machine, press the “drain” button and water is discharged through the accumulation tray of the water pump.

5. GPP button

   • For switching between RH humidity mode and GPP moisture content mode; GPP moisture content range from 25 to 200.
   • In RH mode, the relative humidity is displayed and the device operates according to the set value of relative humidity.
   • In GPP mode, the current moisture content is displayed and the device operates according to the set value of moisture content.

6. Aux. Terminal A 1 ~A6

   • A1 and A2 are designed as dry contact, adding a relay on the circuit board, when the machine is turned on, the relay is closed, and when the machine is turned off the relay is disconnected. (Note: If the machine is running by a fault shutdown, the relay will be disconnected, such as E4, H1, LO, etc. Defrosting is in normal working condition.)

   • A3 and A4 are designed to be connected to the HVAC system and turn to the HVAC control after pressing the HVAC control on/off button. And the machine enters continuous mode and will not be controlled by its own on/off switch, except by drainage and GPP button.
     (Note: A3, and A4 are 24V AC/DC input terminals, when the external HVAC system inputs a 24V signal, the machine will run in continuous mode after receiving the signal. (It will stop if there is a fault such as E4, H1, LO, etc.)

   • AS and A6 is designed for an external pump. When these two interfaces are connected for 14s continuously, the machine will judge the E4 fault and stop the machine. But you can still press the drain button to drain water. After the E4 fault is resolved, it’ll automatically restart without re-powering. (This E4 fault notice is the same as the built-in pump E4 fault.)

Indicator Lights

1. Humidity Display Screen
   The display screen has two functions:

2. When the unit is powered on, it shows the humidity of the space.

3. While setting the desired humidity level, the screen will show the set humidity. After a brief delay, the display will revert to the current humidity level.

4. Power Indicator Light
   This indicator indicates that the device is powered on and ready for operation. Always ensure that the device is in the “off” state before performing any service. After power is powered on, the buzzer will beep twice, and the machine will enter the standby state, and this light is not on. The light is steady on after the machine is turned on and off after the machine is turned off. In other states, the indicator blinks (for example, error codes H1 and LO, humidity reaches slowly blinks, defrosting quickly blinks). (Note: This light is off when an error code E4 stops.)

5. Continuous Mode

   • When this light illuminates green, it indicates that the dehumidifier is set to the continuous operation mode.

6. Pump Pattern Light

   • Water pump mode, this light is on; Gravity drain mode, this light is off. The default mode of the device is gravity drainage.

7. GPP Mode Light

   • When the compressor is in GPP mode, the light is on. In normal mode, this light is off.

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 an 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.

Coil Maintenance

• Once per year, clean the coils with an approved coil cleaner.
• Coil cleaner should be a self-rinsing, foaming cleaner such as WEB® Coil Cleaner.

Dehumidifier Storage

If the unit will be stored for an extended period of time, complete the following steps:

1. Turn off the unit and allow it to dry.
2. Wrap and secure the power cord.
3. Cover the filter mesh.
4. Store in a clean, dry space.

Troubleshooting

If a pump alarm is shown on the display, complete the following steps:

1. Reset the unit by disconnecting the power cord and then reconnecting it.
   NOTE: THE UNIT WILL NOT FUNCTION UNTIL THE ERROR CODE HAS BEEN CLEARED.

2. Manually check to see if the pump is operational by pressing the drain button. Check if the pump ener­gizes and de-energizes properly. Additionally, check to see if any water purged from the system.

3. If you haven’t cleaned the system recently, check the discharge line for obstruction, then clean the balance of the pump system (see “Maintenance” on page 8 for details).

4. Replace the hoses and/or pump, if maintenance alone isn’t sufficient.

Water Pump Matainence and Application

Normal use of water pump

1. 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.

2. 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.

3. Turn on the power and run the dehumidifier
   lf 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

1. 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.
2. The drainage pipe can be laid at will, without space restriction, up to 19.6 ft.
3. 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.
4. The advantages of the water pump itself, are low noise, low vibration, small size, long life, self-priming function, simple maintenance, and easy replacement.
5. Use the rubber stopper to plug the drain hole when you use the pump drain.

The fault judgment and maintenance method of the water pump

Problem judgment when the “E4” error code appears:

1. The drainage hose is blocked or bent and deformed by foreign matter.
2. The drainage height exceeds the standard.
3. Water level switch failure.
4. Water pump failure or expiration of service life.
5. The internal water pump hose is blocked or bent and deformed by foreign matter.

Pump repair method

1. Use a Phillips screwdriver to unscrew the five screws on the water pump panel, you can see the fixed state of the water pump.
2. Use a Phillips screwdriver to loosen the two screws of the water pump fixing bracket.
3. Pull out the hose fixed in the water storage box, and take out the water pump for replacement.
4. Install the new water pump to its original position according to the above steps.
