ALORAIR HDi90 Duct Able Version Basement Crawl Space Dehumidifiers

Warranty Registration

• Comes tulion epsire warany elan. To register, simply email us and remit the warranty form provided in your 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 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 it to another location.
• If there is a chance that water floods 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 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 objects 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. 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.

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 unit.

Model Number: Sentinel HDi90

Electrical Supply

• Power Supply: 115 V, 60 Hz AC, Single Phase
• Outlet Requirement: 3-Prong, GFI
• Circuit Protector: 15 Amp

Principle of Operation

• The Sentinel Series Dehumidifiers utilize 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 vapour 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 vapour 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 the unit directly on the vapour 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, and then wait a minimum of 2 hours before turning “on”.

• Step #2: Set Up 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 com pletely. Tighten the compression nut.

• Step #3: Plug the 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 two beeps 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 shutdown.

Arrow Buttons

• Use the up and down arrow buttons to set the desired humidity setpoint on the display screen.
• The set point can be any number between 36-90%. 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%).

Continuous Mode

• To switch into continuous mode, simply use the down arrow key to set the humidity below 36%. At this point the Cont. light should illuminate green on the display board to indicate you have successfully switched to continuous mode. The display screen will show “CO”.
• When set to continuous, the dehumidiffer will run constantly, regardless of the humidity level until you 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 above 36%.

Central Control

• This model does not apply to the Sentinel HDi90.
• The central Control light should be 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.

Pump Trouble Warning

When the pump reservoir water level is too high, the high water sensor will activate to prevent overflow. When this occurs, the dehumidifier will stop the compressor automatically and the display will show “E4”. After a 1 minute delay, the fan motor will turn off and the machine will not operate until the problem is resolved. To reset the unit after an “E4” error, check the pump to verify it is functioning, then unplug the unit for two minutes.

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.

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 the 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” before performing any service.
• When the power light is blinking, it means that the unit has reached the humidity setpoint.

Continuous Mode/Auto Defrost Light

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

Compressor Light comp

• 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 an area that’s difficult to access regularly. 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.
