The following safety guidelines must be strictly observed.
• Leave this manual at the place of installation of the product.
• It is essential that only the manufacturer or its appointed agents carry out
maintenance and servicing work.
Users, maintenance and servicing personnel must be familiar with:
• Accident prevention regulations.
• Safety information (general and specic to the unit).
• Safety devices of the unit.
• Measures to be taken in case of an emergency.
• Allow only suitably trained persons to be involved with installation, start-
up, operation, servicing and maintenance of the product.
• It is the responsibility of the installer to ensure that the pipe work to and
from the dryer is suitable, in accordance with applicable legislation and
subject to inspection and testing prior to being put into service. All piping
must be adequately supported.
• Before carrying out any maintenance or servicing work the unit must be
taken out of operation. Users and others will be exposed to risk if work is
carried out while the unit is running. This means electrical disconnection
plus isolation from the compressed air supply and full depressurisation.
• Only trained and competent persons familiar with the electrical
requirements of the unit as laid out in this manual and electrical safety
rules and regulations should be allowed to carry out work on the
electrical components and power supply to the unit.
• When carrying out any work on the unit, use only correctly sized
appropriate tools in good condition.
• Only use original spare parts and accessories from the manufacturer.
There is no guarantee that non-original parts have been designed
and manufactured to meet the safety and operational requirements
of the unit. The manufacturer assumes no liability for any equipment
malfunction resulting from the use of non-approved parts.
• If carrying out installation work above head height, use suitable and safe
working platforms or other means of working access.
• Do not make any constructional changes to the product. Any changes or
modications may only be carried out by the manufacturer.
• Any faults or defects that could affect safety must be put right fully
before using the unit.
• Used items and materials must be disposed of in the correct manner,
complying with local laws and regulations, in particular the desiccant
cartridge.

Manual Handling
As with all areas of the workplace, Health and Safety is of great
importance and must be given due care and attention. While working
with this equipment, manual handling regulations must be considered
and adhered to.
Full advice, support and guidance should be detailed in your Health and
Safety Policy and Manual Handling guide, please take the time to familiarize
yourself with these documents.
The Manual Handling Operations Regulations apply to a wide range of
manual handling activities, including lifting, lowering, pushing, pulling or
carrying.
We ask every person handling this product to take the responsibility for their
own Health and Safety and the Health and Safety of others around them. If
you feel there is a signicant risk, you must take steps to either remove the
risk altogether, or reduce the risk prior to carrying out the activity. If you need
further support or guidance with this, please consult your line manager or
the HR Department.
There are safe systems of work and correct procedures in relation to manual
handling, please consult these documents available within the workplace.
We ask everyone handling this product to:
• Follow appropriate systems of work laid down for their safety.
• Make proper use of any equipment provided for their safety.
• Inform the company if they identify hazardous handling activities.
• Take care to ensure that their activities do not put others at risk.
If in doubt, please seek further advice and ensure you always follow the
correct procedures and guidance.
A 3 amp fuse should be tted as per the wiring diagram.
For more information please see our Health and Safety
manual attached.

7Heatless Desiccant Dryers |Instruction Manual
Function of the Dryer
The dryer is designed to provide a smooth, controlled and uninterrupted
delivery of dry compressed air. Wet air passes through a pre-lter and travels
down to the bottom valve assembly. The air is then fed through the bottom
of the desiccant bed and moves through the high performance desiccant
until it becomes dry. On exit from the desiccant cartridge, the air is passed
through the outlet valve assembly.
During this process, the dryer control system cycles the process air between
the two desiccant towers. While one tower is on stream removing
water vapor, the other is being carefully depressurized in preparation for
regeneration. The desiccant bed is regenerated by expanding a small amount
of dry process air, or purge air, through the saturated desiccant.
Purge air passes to atmosphere through the silencer, which is tted to an
exhaust valve. The tower is then repressurized, with the control system
assuring each tower is at full operational pressure prior to changeover.
This ensures a reliable and efcient operation. The air stream is switched and
the cycle repeats on a continuous basis.

Technical notes
1. Pre-ltration, including a Water Separator is essential to maintain dryer performance.
2. An appropriate Water Separator must be installed. If bulk water enters the adsorption dryer it can cause heat expansion to the
desiccant, substantial rise in the dryer differential pressure, poor outlet dewpoint, potentially resulting in dryer failure.
3. The manufacturer recommends tting a reverse ow 0.01 micron dust lter to the outlet.
4. Call your nearest manufacturer sales team for further information.

Re conguration of the inlet / outlet ports
45 SCFM - 110 SCFM models
• Dryer can be recongured to interchange position of inlet and outlet
ports as per gure 4.8.
• The dryer has two inlet ports (A and B) and two outlet ports (C and D).
Either (A or B) can be used for inlet and (C or D) for outlet. Make sure
the un-used ports are blanked off with provided pressure plugs.
Figure 4.8: Inlet/outlet ports
A
C
B
D
Either of the two outlet ports can be used. Please ensure
that the outlet ow does not exceed specication. Please
adhere to regional regulations.
It is strongly advised to install a non-return (check) valve to
the outlet port of the dryer.
Only use one inlet port at any one time.
Ensure original seals are in place.
Check dryer is leak-free prior to operation.
Ensure that any surges in ow do not exceed the dryers
rated ow capacity.
Tools required
• Adjustable wrench
• Ratchet with 17mm Hexagonal connection

Purge Orice Size Identication
• Reference gure 4.11 and the Purge Plug Identication Table.
• Each dryer is pre-set with the correctly sized purge valve for an operating pressure of 100 psig (7 barg) at point of order.
• The lettering (A through S), located on the purge valve body, indicates the orice size selected to suit the operating pressure of the dryer per the chart
below.
• If the inlet pressure to the dryer will be different than the pre-set orice size, the purge valve can be adjusted.
• Dryers use a single orice purge valve represented by the Red and Blue single letter references in the table below.
• To select the correct orice size, locate the appropriate dryer model at the left side of the table and then the operating pressure at the top.
• Make sure that the correct orice disc (01, 02) has been supplied with the dryer. The discs have the number (01, 02) stamped out at the top.
Every dryer is shipped with a purge orice set up for 100 psig (7 barg) operation. The dryer will also include the necessary purge valve components
to congure the dryer to operate at any pressure from 58 psig (4 barg) to 189 psig (13 barg). For example: A 110 SCFM dryer will be supplied with a
single hole purge assembly with an 02 purge disc installed and indexed to position A. Additional purge valve components will be included to allow
the dryer to be congured to purge settings,
CK, M, G, C, B, A, S, S and P.
Appropriate purge plug selection is very important for function of the dryer. Failure to comply with this may affect your warranty.
