UNPACKING
-WARNING
HEAVY ITEM
Carefully remove the DD3000 dehumidifier unit from its transit box 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, it will be useful when transporting the dehumidifier unit in the
future.
INTRODUCTION
Dehumidifiers remove moisture from the air that is circulating through the unit.
The resulting reduction of relative humidity helps prevent rust, rot, mould,
mildew and condensation within the room, or other enclosed spaces where
the dehumidifier is used.
The DD3000 is of the desiccant wheel type designed to dry air by passing a
large volume of air, the “process” air through a slowly rotating Silica gel rotor.
Silica gel is a hygroscopic material that absorbs moisture direct from the air.
As the air passes through the rotor the humidity of the air is reduced, whilst
the moisture content of the rotor is increased. A smaller volume of air, the
reactivation air, is heated by an internal heater and passes through a portion
of the rotor in the opposite direction. As this heated air passes through the
rotor it will “reactivate” it by removing the moisture content from the silica gel
material. The reactivation air will leave the humidifier as warm, moist air and
must be vented to outside of the building.
Continuous circulation of the air through the dehumidifier unit gradually
reduces the relative humidity in the space.
The DD3000 dehumidifier is a robust unit designed to control the humidity in
the enclosed space in which it is placed. The casing is fabricated from Steel
then painted and has been designed for the exacting conditions which can
prevail in offices, shops, houses, restaurants, public houses etc. It combines
compactness with high reliability and strength.
The unit is thermally protected and will automatically switch off in excessive or
abnormal conditions.
The dehumidifier has two separate filters. One in the “process” air inlet and
one in the “reactivation” air inlet, used to clean the air entering the
dehumidifier.

UNIT CAPACITY
The ambient conditions of the area to be dehumidified will determine the
amount of water extraction the unit is cable of.
Measure the ambient conditions of the area to be determined and then use
that information with the following capacity diagram to determine the unit
capacity.

INSTALLATION
The DD3000 is designed for indoor use. The unit should be placed on a level
surface and a space of 1 meter free around all faces to allow access for any
duct work and servicing.
Connecting duct work:
The regeneration outlet must be ducted to outside the area being
dehumidified. The outlet duct spigot is 10” diameter and only 10” ducting or
greater should be attached. A damper for adjusting the airflow must be
installed
The process outlet can be ducted to a specific area or another room. The
outlet duct spigot is 16” diameter and only 168” ducting or greater should be
attached.
Both the regeneration and process air inlets are provided with filters. The
dimensions of the ducts are as follows:
Process air inlet L 740mm x W 535mm (29.1” x 21”)
Regeneration air inlet L 485mm x W 485mm (19.1” x 19.1”0
Power Supply & Humidistat Control:
The unit must be connected to a suitable 460V, 3 phase, 50Hz supply.
Feed power cables through the gland provided and then wire the unit as
shown below.
An external humidistat can also be used to control the relative humidity in the
dehumidified area. If a humidistat is used then the wires should pass through
the gland provided and then wired as shown in the diagram at the back of this
manual.

Control Settings
Once the unit is positioned correctly, required duct work attached and the
power supply connected, the process fan speed and temperature control need
to be set correctly.
The fan speed control is located within the main electrical control. The
controls are numbered 1 to 10, with 10 being the maximum speed.
For normal (efficient) operation the process airflow should be set to 3000m³/h
(1766 cfm). Measurements should be taken at the duct outlets using a
suitable instrument.
The regeneration air flow is fixed and cannot be adjusted. Setting of the
correct airflow is to be carried out by the installation of a damper control
within the regeneration outlet airstream,
The temperature control regulates the temperature of the reactivation airflow
onto the desiccant wheel. The control can be set up to a maximum of 145°C
The controller displays the set value (Green display) and also the actual value
(Red display)
To adjust the temperature control simply press the ▲or ▼buttons to select
the required setting. The controller will automatically store this value.
The temperature setting should be set to 90°C above the ambient
temperature of the area being dehumidified
If high moisture extraction is required it will be necessary to increase the
process airflow. The temperature control setting should also be increased.
If very low humidity levels are required then the process airflow should be
reduced.
The following table should be used as a guide:

FAN PERFORMANCE CURVES
For example:
If the total system resistance is 600pa then the process fan selector would
have to be set to No 5 to achieve the required airflow of 3000m³/h (1766 cfm)
For example:

Drawing : TPC465
Issue : C
Date : 05/01/2017
If the total system resistance is 800pa then the regen airflow will be 750m³/h
(441 cfm). Adjustment of the damper may be required to achieve the required
regeneration airflow.
OPERATION
The electrical controls are located on the front of the unit. They are:
•ISOLATOR
•On / Off Switch
M
Dehumidifier in continuous operation
A Dehumidifier operation by means of an external
humidistat

Dehumidifier OFF
•An hour counter is provided to display the total time the unit has been
in operation
•DRYING lamp (GREEN) – unit is in drying mode.
•HEATING lamp (GREEN) – indicates heating elements are on. Cycle
on/off when in drying mode.
•OVERLOAD FAULT lamp (RED) – Fault on the regeneration motor
•PROCESS FAN FAULT lamp (RED) - Fault on the process motor
•HIGH TEMPERATURE FAULT lamp (RED) – Overheat protection
within the heater duct has operated
To start the dehumidifier, switch the ISOLATOR to the ON position. The
temperature controller will illuminate, showing the current temperature and the
set temperature for the heaters.
Adjust the On / Off switch to position M. (Manual for continuous operation)
After a slight delay the fans will operate – air can be felt blowing from the air
outlets and the heater will come on.
Both the HEATING and DRYING lamps will be illuminated - the unit will
operate continuously at this setting.
If an external humidistat control is fitted, turn the unit to switch to position A.
Depending on the setting of the humidistat, the dehumidifier may switch off as
the relative humidity in the room decreases. As the humidity increase the unit
will automatically switch back on.

High Temperature Cut-Out:
The DD 3000 dehumidifier has been designed to work in ambient conditions
of -20ºC to +40ºC. Should the temperature in the room become excessive a
manual overheat protector will operate, switching off the heaters. The fans
and drive motor will continue to operate but the HIGH TEMPERATURE fault
lamp will illuminate. Prior to resetting the protector, check that the
dehumidifier is installed correctly and the ambient temperature does not
exceed 40°C.
See repairs section for details on resetting device.
Motor Protection:
The process fan motor and regeneration fan motor are provided with
protection in the event of failure.

ROUTINE SERVICE & REPAIR
To ensure continued full efficiency of the dehumidifier, maintenance
procedures should be performed as follows:
•We recommend that the filters are checked at least once a month.
Intervals for cleaning or replacement of filters will depend on the
installation
•Never operate the dehumidifier without the filters, as the rotor can be
damaged by dust.
To carryout the following, it is necessary to remove the side panels.
This machine should be serviced by qualified Ebac Industrial Products Ltd
personnel or other persons having technical competence in servicing
electrical equipment following the instructions in this Service Manual.
•The rotor is maintenance free. However, should it be necessary to
clean the rotor, compressed air should be used to carefully blow dirt
from the rotor.
•The heaters are maintenance free. However should it be necessary to
clean the heaters, compressed air should be used to carefully blow dirt
from the heaters.
•Check that the fans are firmly secured and that the fan rotates freely.
•Check all wiring connections.
•Check the belt tensioning at regular intervals.
•The overheat protector is located inside the control panel. To reset this
device press the red button.
