How Your Storm Dehumidifier Works

The Storm Pro dehumidifier /The Storm Ultra dehumidifier utilize its integral humidistat to monitor the conditioned space. Once conditions are outside the desired setpoint, the compressor energizes and air is drawn across an evaporator coil. The evaporator coil is cooler than the dew point of the air so water vapor will turn into liquid condensation. The air is reheated through the condenser coil and distributed back into the room.

Compressor on waiting interface display

Compressor protection time not shown:ALORAIR Storm Ultra Commercial Dehumidifier-13“Compressor ready IN 03:00” indicates: That the interface will be displayed when the compression is in a protected state. (including power-on and shutdown, the humidity rises immediately after the arrival of LO HI, and the shutdown resumes immediately after the emergence of LO H/). Displays the countdown in seconds. If the above situation does not occur within 3 minutes, it is not shown.

Water Pump working interface display

Compressor protection time not shown:ALORAIR Storm Ultra Commercial Dehumidifier-14“Pump working countdown”: Indicates: No matter in which working state and interface, as long as the pump works, this interface appears and counts down to 28 seconds.However, the interface only displays the previous working status and interface after 3 seconds. For example, after 3 seconds, there is a drainage icon on the main interface and it will flash until the drainage is finished.

Interface display in case of failure

Machine running time fault display:ALORAIR Storm Ultra Commercial Dehumidifier-15Make fault judgment and take corresponding actions after starting up. Regardless of the state, the fault is executed first and the fault code is displayed on the interface. If there is a fault in the sub-menu operation, immediately return to this interface display fault (including defrosting state). (The fault is judged when the pump works, and the fault is displayed as usual, but the pump needs to complete the water pumping this time). Multiple faults can be displayed at the same time.

Description of fault display:

  • Humidity sensor fault: when the humidity sensor unit fault or signal can not be transmitted, the fault is judged to be E1. The machine is out of operation (power on again after troubleshooting). The pump button can operate.
  • Ambient temperature T<2: When the sensor continuously detects the ambient temperature of inlet air T=2 degrees for 600 seconds, the fault is judged to be LO and the whole machine is stopped. Other values, correspond to the temperature region operation. (recoverable). At this time, the interface cannot be operated. The pump button can be operated.
  • Ambient temperature T>45: When the sensor continuously detects the inlet air environment temperature T=45 degrees for 15 seconds, the fault is judged to be Hl and the whole machine is stopped. Other values, correspond to the temperature region operation. (recoverable). At this time, the interface cannot be operated. The pump button can be operated.
  • When the compressor is started, if the coil temperature value detected is greater than or equal to (ambient temperature -3 degrees) for 30 minutes continuously, it is judged to be fluorine deficient (except defrosting), E5 is displayed, and the machine cannot be stopped for operation (It needs to be powered up again after troubleshooting).
  • After the power is back on, the machine runs continuously for another 30 minutes for judgment. (The temperature probe is broken, the temperature needs to be minimal). The pump button can be operated. After the pump works for 28 seconds when the high water level is switched on, E4 fault is judged when the high water level switch is switched on for 3 consecutive seconds, and E4 fault is displayed. The machine stops and cannot be operated (The pump needs to be powered up again after troubleshooting). The pump can be operated.

Preparing the Unit for Use


  1. Position the machine so there is a minimum of 8″ clearance for the back and sides. or directly toa specific location for spot dry. If the compressor didn’t remain vertical during transportation, wait a minimum of 30 minutes before turning the unit on.
  2. The included drain line attaches to the unit via a quick connection fitting that is located on the base of the unit. The drain line should be routed to a suitable drain or outside. Since the unit has an integral drain pump, the drain line may go up vertically (no more than 15′) prior to reaching the final drain location.ALORAIR Storm Ultra Commercial Dehumidifier-16ALORAIR Storm Ultra Commercial Dehumidifier-17
  3. Firmly insert the power cord into the socket on back of the unit under the air outlet.
  4. Turn on the dehumidifer and use the control panel to set up the dehumidifier as desired.

Optional Duct Installation

Ducting of the unit allows you to condition an adjacent room or focus the discharge to a specific area. The diameter for the supply/discharge ducting is 6″.Flex or layflat ducting can be used for this purpose.ALORAIR Storm Ultra Commercial Dehumidifier-18

Integral Pump Maintenance

NOTE: This pump requires routine maintenance that is not covered by your 1 year parts warranty. Only a defective pump will be repaired or replaced under the warranty. As with all pumps, preventative maintenance is necessary to prevent issues from dirt and slime that may accumulate in the drain system. This includes the drai pan, hose to the condensate pump, pump reservo ir, pump head, float assembly, and discharge tubin The pump 1s des1gned wi th quick connection construction, making it easy to access the pump and components for service and maintenance. To Remove Pump from Reservoir:

  1. Unplug the unit.
  2. Upen the back housing as shown on page l12.
  3. Remove the condensate tube from the pump.
  4. Use the quick connect fittings to disconnect the main power and float switch electrical cable
  5. Use a flathead screwdriver to gently pry the pump off the reservoir.

At least once per year, clean your pump system. Basic Pump Cleaning:

  1. Press the pump button (PURGE) to drain any water from the reservoir.
  2. Disconnect power to the dehumidifier.
  3. Mix a 16 oz cleaning solution of one of the following: I 0z bleach / 15 oz water or 4 oz white vinegar 12 oz water. Pour the solution into the drain tray at the base of the coils.
    NOTE: If you get any cleaning solution on the coils, flush with water
  4. Allow cleaning solution to soak for 15 minutes.
  5. Reconnect power to the dehumidifier.
  6. Pour clean water into the reservoir so the pump activates twice (about 16-32 0z. water).
  7. Repeat if needed or refer to Advanced instructions.
Advanced Pump Cleaning
  1. Use the manual pump button (PURGE) , to drain any water from the reservoir.
  2. Unplug the unit, and remove pump from reservoir (see page 13).
  3. Use a wet dry vac or paper towels to remove any rema in ing water from the pump reservoir.
  4. Fill the pump reservoir with a cleaning solution (15 oz water /1 oz bleach or 12 oz water /4 oz white vinegar).
  5. Reassemble the pump and use the manual pump button to flush the mixture through the discharge tubing.
  6. Mix another batch of cleaning solution then pour it slowly into drain pan under evaporator coil and allow it to clean the hose from pan to pump. This process can be stopped when the pump energ1zes I time.
    NOTE: If you get any bleachwater mixture on coils, flush with water.
  7. Pour sufficient clean water through the drain pan so that the pump activates twice (16-32 ounces).
  8. Reassemble the unit and return it to operational status.

Cleaning the Coils

The coils on your dehumidifier also need to be cleaned once per year. To clean, simply spray with a self-rinsing, foaming coil cleaner (such as WEB Coil Cleaner).

Storing Your Dehumidifier

If you plan on storing your dehumidifier for an extended period of time

  1. Turn unit off and allow to dry.
  2. Manually drain pump reservoir.
  3. Wrap and secure the power cord.
  4. Clem the filter.
  5. Store in clean, dry environment.

E5 Error Code Refrigerant Leak Contact Your Installer for Assistance

If an E4 code appears on the display:

  1. Reset the unit by disconnecting the power cord and then reconnecting it.
    NOTE: The unit will not function until the code has been cleared.
  2. Manually check to see if pump is operational by pressing the drain button. Verify that 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 an obstrution, then clean the balance of the pump system (see “Maintenance” section for details).
  4. Replace the hoses and/or pump, if maintenance alone isn’t sufficient.
