UNPACKING

 

 

Carefully  remove  the  CD425  dehumidifier  unit  from  its  packing  and  visually 
check  for  signs  of  transit  damage.  If  there  is  evidence  of  damage  DO  NOT 
attempt  to  operate  the  unit,  call  your  supplier  for  advice.  Do  not  discard  the 
packing,  as  it  will  be  useful  when  transporting  the  dehumidifier  unit  in  the 
future. 

 

INTRODUCTION 

 

The  Ebac  CD425  dehumidifier  removes  moisture  from  the  air  that  circulates 
through  it.  The  resulting  reduction  in  relative  humidity  protects  buildings  and 
their contents from the adverse effects of excess humidity. 
 
The CD425 Dehumidifier comprises of: 
 

a)

  A compressor 

b)

  Refrigerant evaporator coils 

c)

  Refrigerant condenser coils 

d)

  Circulation fan 

e)

  A drain tray for collecting and disposing of condensed moisture 

f)

  A cabinet to house the above components. 

 
The fan  draws  the  moist  air  through  the  evaporator  coils  which  cools  the  air 
below its dew point. Moisture forms on the evaporator and is collected in the 
condensate tray which leads away to a permanent drain. The cooled air then 
passes  through  the  hot  condenser,  where  it  is  reheated  using  the  same 
energy  removed  during  the  cooling  phase  and  the  additional  heat  generated 
by the compressor. The air is, therefore, discharged from the dehumidifier at a 
slightly higher temperature, but a lower relative humidity, than that at which it 
entered.  Continuous  circulation  of  air  through  the  dehumidifier  gradually 
reduces the relative humidity within the area being dehumidified. 
Where large amounts of moisture are required to be removed from the area, 
more  than  one  dehumidifier  may  be  required,  please  contact  your  local 
distributor for advice.
