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
