Operation - Ecor-Pro DDH3500 Manual

POSITIONING
The DDH3500 is designed only for indoor use however, it can be placed
inside or outside the room to be dried.
Internal Positioning:
When positioning the unit inside the room, place centrally, ensuring inlet and
outlet ducts are clear of obstruction.
If required, ducts can be connected to the outlet and/or inlet to direct the dry-
ing to specific areas.
The Wet-Air-Out and Regen-Air-In MUST be ducted to and from outside the
room.
External Positioning:
When positioning the unit outside the room, connect ducting to the outlet to
direct the dry air stream into the room to be dried. The Process-Air-Inlet inlet
should also be ducted to the room to give a re-circulation effect.
Note:
As the Wet-Air-Out discharge is warm and very humid ensure it is directed
where it will have no adverse effect on the immediate environment.
All ducting lengths should be kept to a minimum - longer lengths will reduce
performance.
The Wet-Air-Out is warm and humid, when a duct is attached, condensation
may form on the inside of the duct. This duct should slope downwards away
from the unit to prevent ant condensation running back into the unit.
CONTROLS
The controls are positioned on the front of the
unit next to the air outlet duct, they are:
• Power Switch
• Ammeter
• Hour Meter
• Remote Humidistat Switch
• Remote Humidistat Connector

OPERATION

Stand-Alone Operation:
Connect unit to suitable mains supply
Ensure 'Remote Humidistat' switch is set to 'OFF' position
Switch 'Power' switch to 'ON' ( I ) position.
The fan will start and the Ammeter reading will rise. (The ammeter indicates
the current taken by the PTC heater bank. Its reading will depend on the 'Pro-
cess' air temperature and the 'Regen' airflow. Typically, it will indicate between
4 and 6 amps - this will reduce if the airflow is low or the Process air tempera-
ture is high.
Remote Operation:
For remote operation it is necessary to connect a switch or humidistat via the
'Remote Humidistat Connector' - this can be accessed by removing the dust
cap. A connection plug is available on request.
ATTENTION - The remote connector is mains voltage!
The remote switch/humidistat should be connected between pins 1 and 3.
The Earth pin is connected to ground and can be used if required. (see wiring
diagram)
The 'Remote Humidistat' switch should be set to the 'ON' position.
The unit will now operate according to the state of the remote switch.
Air Filter:
The DDH3500 has an inlet air filter, this should be checked periodically and
if necessary cleaned. It can be cleaned with a vacuum cleaner or washed in
mild detergent.
ATTENTION: Do not run the unit without a filter fitted as dust will impair the
performance of the Desiccant Rotor.
