SPECIAL FEATURES (where fitted)
CONDENSATE PUMP:
The CD-35 dehumidifier unit can be fitted, either in the factory, or as retro-fit,
with a condensate pump. This condensate pump will allow the unit to run
unattended, with the condensate run off to a permanent drain and can be
used up to 150 feet (50 meters), below the level of a permanent condensate
drainage point.
HUMIDISTAT CONTROL:
The CD-35 dehumidifier unit is fitted with a control humidistat which measures
the relative humidity of the air within the room. The humidistat incorporates a
pointer and scale, which can be adjusted, and set to a relative humidity level
that is acceptable to maintain the required conditions within the room. The
humidistat controls the on/off function of the dehumidifier. When the relative
humidity of the air in the room falls below the set point of the humidistat the
dehumidifier will switch off, but when the relative humidity of the air starts to
rise again and passes the set point the unit will switch on. The humidistat is
used for the on/off function as it is a cost effective method which ensures
power is only used when needed.
TEMPERATURE CONTROLLED DEVICE:
The CD-35 dehumidifier unit is fitted with a temperature sensitive device
which operates in conjunction with the defrost control. In normal operation the
defrost control will come into operation every 45 minutes. This is to ensure
that there will be no build up of ice at lower temperatures.
temperatures it is still possible for the defrost device not to clear the ice
completely from the evaporator coil. To ensure that even at these very low
temperatures all the ice is cleared from the coil, the temperature control
device will stop the fan (preventing air movement). This will increase the
temperature of the evaporator coil even higher, causing all the ice to melt from
the coil during the defrost mode. Where year round conditions need to be
maintained, the dehumidifier unit will have to operate across a wider range of
temperatures.
To ensure that the dehumidifier unit operates at its most
efficient, the temperature control device will restrict the defrost operation to
the times when the ambient temperature falls below 25° C.
