3.1 Receiving and Inspecting the Equipment
The equipment is supplied in a sturdy wooden crate designed to be moved using a forklift truck or pallet truck. On delivery of the equipment check
the crate and its contents for damage and verify that the following items have been included with the dryer. If there are any signs of damage to the
crate please inform the delivery company immediately and contact your local Parker domnick hunter office.
3.1.1 Storage
The equipment should be stored, within the packing crate, in a clean dry environment. If the crate is stored in an area where the environmental
conditions fall outside of those specified in the technical specification, it should be moved to its final location (installation site) and left to stabilise
prior to unpacking. Failure to do this could cause condensing humidity and potential failure of the equipment.
3.1.2 Unpacking
The panels of the crate are secured using nails. Starting with the top, carefully remove each panel in turn and store them safely for future use.
3.1.3 Lifting and Handling
The purifiers are heavy and should be lifted into position using suitable lifting equipment. Lifting pockets have been provided on the BA-DME050-
E - 080-E modules to facilitate lifting with a fork lift truck.

4 Installation and Commissioning
4.1 General
The module should be installed, downstream of a 'wet' air receiver. Additional condensate management equipment may be installed to meet both
the specification and local environmental requirements.
4.1.1 Locating the Equipment
The equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in temperature,
humidity, and airborne pollution will affect the environment in which the equipment is operating and may impair the safety and operation. It is the
customers' responsibility to ensure that the environmental conditions specified for the equipment are maintained.
4.1.2 Space Requirements
The equipment should be mounted on a flat surface capable of supporting its own weight plus the weight of all ancillary parts. The minimum
footprint requirements are specified below, however there must be adequate space around the equipment to allow airflow and access for
maintenance purposes and lifting equipment. A minimum spacing of approximately 500mm (20 ins) is recommended around all sides of the
modules and 1000m (39.4 ins) above it.
Do Not position the equipment so that it is difficult to operate or disconnect from the electrical supply.
4.2 Mechanical Installation
4.2.1 General Requirements
Ensure that each filter condensate drain is suitably piped away and any
effluent is disposed of in accordance with local regulations.
It is important to ensure that all piping materials are suitable for breathing
air applications, clean and debris free. The diameter of the pipes must be
sufficient to allow unrestricted inlet air supply to the equipment and outlet
air supply to the application.
When routing the pipes ensure that they are adequately supported to
prevent damage and leaks in the system.
All components used within the system must be rated to at least the
maximum operating pressure of the equipment. It is recommended that
the system be protected with suitably rated pressure relief valves.
4.2.2 Securing the Dryer
Once positioned, the equipment may be secured to the floor using M12
bolts. Four mounting holes are provided in the base of each dryer (BA-
DME012 - 040) and on the base of the skid frame (BA-DME050 - 080).
4.2.3 Piping Connections
Remove the protective dust covers from the inlet and outlet ports and
connect the system piping. Isolation valves should be fitted to both ports
to allow the module to be isolated during maintenance.
4.2.4 Purge Air Flow
The purge air flow is factory set for 6 bar g (87 psig) minimum system
pressure. Should the minimum supply pressure be higher or lower than
this figure the air flow must be reset in order to maintain the specified
dewpoint.
The purge should only be set by Parker domnick hunter approved
service personnel.

4.3 Electrical connections
4.3.1 Connecting the electrical Supply
The dryer is supplied with a C14 IEC wireable inlet socket. This socket
should be wired using 1.0mm2Tri rated cable. We recommend that
the cable be no longer than 2m in length.
Check the rating plate for the correct supply voltage and frequency.
Connect the electrical power cable, supplied with the equipment, to
the IEC320 socket and engage the wire retaining clip. Connect the
plug directly to the electrical supply, do not use an extension cord.
Note. The IEC socket has an integral fuse fitted, replacement fuses
should be of the type detailed in the technical specification.
4.3.2 Auxiliary Connections
The dryer can be connected to external control and alarm circuits
using the dedicated terminals on the timer board located inside of the
control box.
Fault Relay Output
This provides a 24Vdc drive for an optional relay (24Vdc 1W max) for
remote indication of a fault condition. Under fault conditions this signal
is removed.
Refer to “Power Indicator and Fault Indicator Operation” on page 14
for operating status of these relays.
Stop / Start (Standby)
The operation of the dryer can be controlled remotely. Applying a
24Vdc signal to this input will put the dryer into standby mode.
External Dewpoint Sensor
The DDS and Dewpoint Alarm Inputs provide the interface with
external dewpoint sensor. Please contact dhFNS for advice.
A fully qualified electrical engineer must undertake all field wiring and electrical work in accordance with local regulations.

Purge Economy
Allows the dryer to be controlled based upon demand. Applying a 24Vdc signal to this input will freeze the dryer’s cycle and close the exhaust
valves. The dryer will remain in this operating state until the signal is removed, at which point it will continue cycling from the stage in the cycle
when the signal was applied.
Connecting to the Auxiliary Connections
1 Unscrew the facia screws and carefully pivot the facia forward.
2 Disconnect the tubes from the pressure gauges.
3 Gently prise the facia away from the body of the dryer, at the pivot points, and rest the facia on the floor.
4 Remove the control box lid.
5 Use the spare glands on the side of the control box for cable access.
Fault Relay Output
6 Referring to the image below for guidance, connect the coil of the switching device to the terminals #3 and #4 of the digital outputs
connector.
Stop / Start and Purge Input
7 Connect terminal #1 of the digital outputs connector (24Vdc) to the common pole of the switching device.
8 Connect the required contact of the switching device to the required terminal of the digital outputs (Stop / Start - terminal #3, Purge Input -
terminal #4).
Note. The image below shows connection to the normally open contact of the switching device, however the configuration of the contacts is
dependent upon the customers system.
Purge economy should not be used if a wet air receiver is installed between the compressor and the dryer as this could lead to overflow of
the dryer with the possibility of performance degradation or deterioration of the desiccant.
Only use a volt free contacts such as a dedicated pressure switch, relay or auxiliary on the compressor contactor. It is not designed to be
used with a current or voltage input.
Ensure wire lengths do not exceed 3m.
Ensure that the dryer is isolated from all supplies prior to connection.
The electrical enclosure will contain more than one live circuit as the relay connections will remain live when the supply to the dryer has been removed.

4.4 Initial Start Up
4.4.1 Getting Started
Before starting up the system check the following:
1 The dryer has been installed correctly as detailed in this guide.
2 The inlet and outlet ball valves are closed and all covers on the BA-DME are fixed securely in place.
3 A suitable supply of compressed air is available, refer to the technical specification for compressed air requirements.
Note. If a refrigeration dryer has been installed upstream of the adsorption dryer unit the refrigeration dryer must be switched off for at least
one week prior to the start-up of the adsorption dryer unit. After this period the refrigeration dryer can be put back on line. Should the
adsorption dryer unit switch into ecomode earlier than this, the refrigeration dryer can be placed immediately on line again.
4.4.2 Start-Up
1 Switch on the electrical supply to the dryer and verify that the yellow “power on” LED on the control panel has illuminated.
2 Slowly open the inlet ball valve until fully open, the adsorption dryer will commence cycling.
3 Verify that there are no leaks within the system.
4 Test the condensate drains of the coalescing filters and verify that they are discharging correctly into a suitable collection vessel.
5 When the dryer is pressurised to full system pressure, slowly open the outlet ball valve.
6 Verify that the column pressure gauges are cycling between zero and full system pressure every three minutes.
7 The dryer will continue to cycle automatically without further intervention.
Note. It will take a period of time for the dryer to reach the specified pressure dewpoint of -40oC. Once the required dewpoint has been
reached the system is ready for use, and the upstream refrigeration dryer (if fitted) can be placed back on-line.
All valves must be opened and closed gradually. Pressure peaks will lead to a destruction of the filters and the desiccant.

5 Operation
5.1 Normal Operation
During normal operating conditions, the BA-DME is fully automatic and
requires no further attention until shutdown. In this state the power indicator will
be illuminated continuously.
The BA-DME range of desiccant dryers operate on the Pressure Swing
Adsorption (PSA) principle to produce a continuous stream of clean dry air. A
dual chamber column, filled with desiccant material, is capped by an inlet and
outlet head to produce a two bed system (A + B). When one bed is online,
drying the compressed air, the other bed is offline regenerating the desiccant.
Drying Compressed Air - Compressed air enters the dryer at the inlet head
and is directed to the online bed by the inlet valves. As the compressed air
flows over the desiccant material, water vapour transfers from the wet air to the
dry desiccant. The clean dry air flows into the to the outlet head, via the outlet
valves, and exits the dryer.
Regenerating the Desiccant - A controlled volume of dry compressed air
(purge air) is used to regenerate the desiccant material within the offline bed.
The bed is at full line pressure when it goes off line. Opening the exhaust valve
causes the pressure to drop and allows the purge air to flow, from the upper
manifold, into the bed. The air within the bed expands from line pressure to
atmospheric pressure and flows downwards over the desiccant material.
Changeover - To maintain the pressure and dewpoint of the air leaving the
dryer, the offline bed must be re-pressurised before the beds change over.
Closing the dryer’s exhaust valve allows the purge air to pressurise the
regenerated bed.
5.2 Dewpoint Dependent Switching (DDS)
The fixed timing cycle above is based upon the dryer operating at its full capacity and the desiccant bed being fully saturated at the point of
change over. In reality dryers rarely operate at full capacity and therefore the desiccant is not likely to be saturated. As the energy used to
regenerate a bed is fixed, more energy (purge air) is consumed than is actually required.
The DDS energy management system incorporates a hygrometer (BA-DME DS models only) that monitors the pressure dewpoint of the air at the
outlet of the dryer. At the end of the half cycle, when the regenerating bed is pressurised (3 minutes), both beds will be at line pressure and no
purge air will be consumed. The dryer is in a state of zero energy consumption. If at this time the air at the outlet is drier than the pre-set dewpoint
(-40oC), regeneration is not required and change over is delayed. The economy indicator will illuminate continuously in this state.
Change over will occur when the pressure dewpoint of the air at the outlet of the dryer reaches the preset level or when the moisture override time
has been exceeded.

Recommended Service
(1) Unlike oil aerosol removal filters which are changed annually to guarantee compressed air quality, the lifetime of an oil vapour removal filter can be attributed to various factors and
require more frequent changes. Factors affecting the lifetime of adsorption filters are:
Oil vapour concentration -The higher the inlet concentration of oil vapour, the faster the activated carbon capacity will expire.
Bulk oil - Adsorption filters are designed to remove oil vapour and odours, not liquid oil or aerosols. Poorly maintained or non-existent pre-filtration will cause the OVR filter capacity to
quickly expire.
Temperature - Oil vapour content increases proportionally to inlet temperature, reducing element life. Additionally, as temperature increases, the adsorption capacity decreases, again
reducing element life.
Relative Humidity or Dewpoint - Wet air reduces the adsorptive capacity of the carbon.
Compressor oil changes - When compressor oil is changed, the new lubricant burns off “light ends” which increases the oil vapour content for hours or even weeks
afterwards. This increase in oil vapour content is adsorbed by the OVR filter, significantly reducing its adsorptive life.
ACS / AC element performance is based upon a maximum oil vapour inlet concentration of 0.018mg/m3, with compressed air at 21oC and a pressure dewpoint of -40oC PDP.
These elements should be replaced upon detection of vapour, odour or taste.
