Frequently Asked Questions - DEH CRAWL SPACE 70 MSW

What are the dimensions and weight of the DEH CRAWL SPACE 70?

The dimensions are 330 x 605 x 380 mm (LxDxH) and the weight is 23.5 kg.

What is the dehumidification capacity?

The capacity is 45 L/day at 30°C and 80% RH, and 26 L/day at 27°C and 60% RH.

How to install the dehumidifier in a crawl space?

Place the appliance vertically on a flat surface. Seal the area with a vapor barrier and plug all vents. Ensure the air inlet has 12" (31 cm) of free space and the outlet has 36" (92 cm). A side panel should face the wall for better diffusion.

How to connect the drain hose?

Route the drain hose to a suitable outdoor drainage. Avoid loops or kinks in the hose. Ensure the passage point is sealed with a vapor barrier.

How to clean or replace the filter?

Unplug the appliance. Open the air inlet plate (held by a magnet) and remove the filter. Vacuum it or replace it. The filter should be changed every 1500 hours of use.

What do error codes E1, E2, E3, and E4 mean?

E1 = coil sensor error; E2 = humidity sensor error; E3 = temperature sensor error; E4 = water tank full or drainage blocked. Replace the faulty sensor for E1-E3, empty the tank or check drainage for E4.

Can I use a remote control or a wall controller?

Yes, optional. You can connect a wall controller via a CAT5 cable (25 feet) or use a remote control. The functions are identical to the built-in controls.

How to set the timer?

Press the MODE button several times until the delayed shutdown time setting appears (display on or off). Use the up/down buttons to adjust from 00 to 23 hours. Confirm by briefly pressing MODE.

Why doesn't the dehumidifier turn on?

Check the power supply and outlet. If the display shows E4, empty the water tank or check the drain hose. Make sure the appliance has been vertical for at least 2 hours.

How does automatic defrost work?

At low temperature, the appliance defrosts automatically. During this phase, the fan continues to run but the compressor stops. The defrost indicator lights up red.

Installation Requirements

The area where the dehumidifier is located should be sealed with a vapor barrier.

If the unit is installed in a crawl space, all vents should be sealed.

For the best air diffusion, install the unit so that a side panel faces the wall.

For proper ventilation, neither the inlet nor discharge should be positioned against a wall. The inlet needs a minimum of 12" (\~31 cm) clearance and the discharge require a minimum of 36" (\~92 cm) clearance.

The dehumidifiers are only intended for operation when the unit is upright and level with the feet on the ground.

Installation

1. Place your dehumidifier on a flat surface.

- Avoid putting it against a vapor barrier. Don't use anything to support it at the base. Place it on the floor. If your device was place in any other position other than upright place it upright and allow two hours before turning it on.

1. Arrange the line of drainage

2. Route the drain hose to a suitable drainage outside.

3. There should not be any loops or dips on the drainage hose.

4. Seal of the point where the dehumidifier is located using a vapor barrier.

5. Seal off all openings if the unit is installed in a crawl space.
6. Avoid placing the inlet and outlet against a wall. This ensures proper ventilation. You need to give a 12" (\~31 cm) allowance of space with the inlet and 36" (\~92 cm) clearance for the discharge.
7. Place the side panel facing the wall so that the dehumidifier delivers the best diffusion.
8. Your dehumidifier is designed to be placed on the ground at the same level with the feet. Place it upright.
9. Maintenance should be conducted with the power switched off or unplugged.

Remote Control Instructions (Optional)

Dehumidifiers can be controlled using optional remote accessories:

Option 1. Wall mounted controller connecting 25'CAT 5 cable.

Option 2. Remote control.

If your dehumidifier is installed in your crawl space, the wall mounted controller could be mounted in your living space or garage. This provides you with an easy way to monitor the dehumidifier. So as the remote control, you can operate the device in a distance.
