EPD50 / DH12XX

The dehumidifier can be placed in many places out of sight including in the attic,cellar, ceiling voids and even in cupboards.

EPD50 / DH12XX has a more powerful turbo fan so longer ducting lengths can be added. Air can be drawn through several vents by ducting to the unit, dried then ducted to a central vent in the home to recirculate.

When ducting is used it is advisable to use an external humidistat EPHUM24DF to get a faster reaction time to changes in humidity. Also draw air from bedrooms or bathrooms to prevent any feeling of draughts.

EPD30 / DH8XX

The dehumidifier is an ideal space dryer. Put in a room, connect the exhaust and simply dry the space. The room can be any room in the home.

Both models are perfect even for outside spaces such as holiday homes & garages as they work below freezing and are unaffected by frost.

Also, both models are very portable so can be carried to places for temporary drying such as boats, RVs & vacation homes.

The EPD50 / DH12XX use a turbo fan and can duct dry air out.

The EPD30 / DH8XX has an axial fan and no exhaust option for dry air.

SIMPLE INSTALLATION FOR THE WHOLE HOME

EPD50 / DH1200 LOCATING IN AN ATTIC

A popular location for the EPD50 / DH1200 is in the attic or in a void in the attic, crawl space or basement.

1, Exhaust the wet air through a duct to an overhang eaves through soffit boards. It is also possible to put the exhaust duct through the gable end of the home. In both instances a suitable vent cover should be used to prevent animals entering the duct and help prevent any wind blowing back into the exhaust. Ensure the exhaust is on a slight decline or insulate the exhaust if not insulated .

2, Push dry air to several points whether bedrooms or bathrooms with ducting. These are usually the worst affected rooms such as spare bedroom or bathroom. Use Y-connectors to increase the number of outlets. Blowing dry air into these rooms may feel draughty only if the air stream is in contact with human skin. Outlet grills should avoid these areas and be position in corners for instance.

3, Damp air from the home can be taken from one central point. Usually, this is on the landing area at the top of the stairs. Moisture in the home will migrate upwards from the lower floor/s. The convection current in the home means damp air rises. Drying homes on one floor may need additional fans to circulate the air or more than one dehumidifier if a larger home. Separate consideration is needed for basements, crawl spaces, attics, conservatories and garages.

4, Leave doors slightly ajar to promote air flow around the rooms

5, A humidistat is built into the EPD50 / DH1200. However, when ducting is fitted to the dehumidifier, it may be necessary to use an external humidistat such as EPHUM24DF which fits in seconds. This humidistat can be placed ideally on the top of the stairs or next to the home heating controls for more accurate monitoring of the air and improves dehumidifier reaction time if that is key.

6, The filter of the dehumidifier will need to be cleaned periodically. To avoid having to go into the attic or ceiling void to clean the filter, consider adding a suitable filter grill to the inlet that includes a dust filter built in. These can then be periodically cleaned rather than the air filter on the dehumidifier itself. That filter can be removed provided they are of comparable filter material which is reticulated foam.

7, On longer duct runs, consider using wider than prescribed to increase air flow to maintain the level of airflow. See below.

8, A power supply to the dehumidifier should be from the mains supply. Although, the maximum power consumption is only 500-550 Watts, power should not be taken from the any lighting circuit. Consult a qualified electrician.

9, Set the RH (Relative Humidity) control to a low (10%) for typically 2-3 weeks. It will work continuously. After the humidity in the home is under control, increase the RH level to a higher level that is right for your home typically 60-65%. In that way the dehumidifier will switch on when needed. Times can be added but we do not recommend. Read More

10, Remember to periodically clean the inlet grill filter.

Ducting Vapour Upwards aND eXTENDING dUCTS

Keep all ducts as short as possible and gradual bends to maximise airflow. If spiral wound flexible ducting is used ensure it is stretched for minimum air resistance. Use smooth plastic such as drain pipe for maximum efficiency. Ensure access to the air filter is possible.

Use wider ducting than prescribed to improve air flow on longer ducts. Check all air flows before ducts are fitted and after to compare performance.

use under the home in crawl spaces, cellars or basements

Both dehumidifiers are ideal for crawl spaces.

Dry air will equalise in the space but it is important there is a flow of air to prevent dead spots. These are pockets of dry or damp air in the room being dried. Use ducting if needed to help circulate & distribute air. It is better to vent trough a duct rather then feed air in via a duct. Additional air movers may be needed over a larger area with low head height. However, ducting air both in and out is also possible on the EPD50 / DH1200.

Allow air to flow around the space. Ensure the dehumidifier is not blowing or sucking air from an alcove, recess, fireplace or corner of the space. Air should be directed in a circular direction around the space being dried.

External air vents can be shut off as there will normally be enough air to replace the exhaust air through other slight openings in the room. Very few rooms are actually air tight. Ensure ducts are short as possible especially the exhaust duct.

Don’t forget to clean the filters. Dust will prevent air movement and the amount of air that can be dried..

DUCTING OPTIONS EPD50 / DH1200

Dehumidifier Installation

This is a 3-Hole dehumidifier meaning that there is one fan inside. It is a turbo fan like the other larger units in the range. Part of the dried process air is turned around, heated and used to purge the internal adsorption wheel of moisture that can be then vented away.

Moisture is "vented away". No water is produced. The moist air is vented to the outside or moved to another area that is well ventilated. Most common installation. If the machine is in the room being dried the internal humidistat can be used to regulate humidity. If ducted and outside the room or house being dried an external humidistat may be needed.

Perfect for crawl space areas or attic areas. Close openings to the crawl space and the unit will regulate the humidity. Use ducting to help spread the dry air around the crawl space area.

Recirculating the air to be dried gives a compound effect and gives faster drying. This system is a "Negative Pressure" system. Air has to replace the air that has been exhausted. In a normal home air is actually being replaced frequently typically 2.5 times per hour. No home is air tight.

The dehumidifier can be hidden from sight. It can be placed in a cupboard, in a ceiling void or under a floor. Dry air is taken from the room, dried and then clean, dry filtered air returned. External humidistat may be needed in that instance.

Strong Machine Even Used For Commercial Spot Drying

The model is build to a standard that professionals can also use. The machine is perfect for focus drying. Wet air is focussed to where the moisture is. Example of "Positive Pressure" or forcing the dry air into areas it is needed

Having the machine in the area being dried and recirculating the air is the most efficient way of drying. This system is "Negative Pressure. In a small enclosure, covered with plastic sheeting a frame is needed to ensure the tent maintains structure. Rooms generally are not air tight so in larger rooms air can leak under doors etc

Used on Boats as a "Carry on" or Installed

Perfect for ducting around the boat or for area such as cabin, engine room or forward locker. Read More

DUCTING OPTIONS EPD30 / DH800

Dehumidifier Installation

This is a 3-Hole dehumidifier meaning that there is one fan inside. It is a Axial fan unlike the other larger units in the range. Axial fans have the advantage of needing less power but have less fan pressure. Fan pressure is needed to force through ducting. That is why there is no ducting flange on the outlet of this unit. Part of the dried process air is turned around, heated and used to purge the internal adsorption wheel of moisture that can be then vented away.

Perfect for crawl space areas or attic areas. Close openings to the crawl space and the unit will regulate the humidity. Use ducting to help spread the dry air around the crawl space area.

The machine can just be put in any room such as a garage. Here the larger model is shown but in smaller garages it can be sufficient. Moisture is simply vented away. To read more about garages see here
