1.3 document introduction
This manual provides factory prescribed installation and maintenance procedures for a series 2 heatless desiccant compressed air
dryer. The procedures illustrated in this document are only to be performed by authorized personnel. For further information regarding
the procedures outlined in this document contact the manufacturer before proceeding. Be sure to read this document carefully before
attempting to install or operate the dryer. This document should be permanently available at the dryer installation site and be kept in
an easily accessible place alongside the dryer.
1.4 warranty guidelines
All products are supplied with a 2 year manufacturer’s warranty from the date of purchase, when installed and maintained in accor-
dance with the manufacturers guidelines. Only genuine service parts should be used and no modications made.
1.5 packaging
All products are securely packaged in a specically designed wooden packing box. The dryer will be held in a horizontal position by
wooden struts; using straps to secure the product to the box base. The box top cover can be removed by removing the 4 xing screws
and lifting off in one piece.
1.6 damage to packaging
Check immediately to establish whether damage has occurred to the external packaging and if the damage extends to the product
inside. If there is damage to a product, contact the relevant supplier immediately.
The support packing box permits limited longitudinal stacking; however the central section of the packing box should not
be considered load bearing.
In no circumstances must a damaged product be used in operation. Using damaged products can lead to
irreparable functional faults or cause serious physical harm.

1.7 general safety
No modications must be made to the product. Any modications may reduce the operational safety of the product and invalidate the
manufacturer’s warranty. This could potentially result in damage to the product and serious personal injury.
For your own safety, when carrying out work on this product, all relevant national safety regulations must be complied with relating to
pressurized and electrical systems.
1.8 intended use of the product
The dryer is exclusively intended for the treatment of compressed air, which is free from bulk water, oil and solid matter constituents.
The product should be located within a building and protected from extreme conditions and weather. The dryer must be operated only
in accordance with the data on the rating plate. Any operations that do not comply with those stated on the product rating label will
render the warranty void.
This product is only designed to operate at pressures of between 6 to 16 barg (58 to 232 psig).
It is not suitable for pressures in excess of 16 barg (232 psig).
IMPORTANT: It is essential that the system into which the dryer is installed is fitted with a pressure limiting/relief
device. This device should be between the compressor and the dryer. The device must be set to prevent the maximum
working pressure of 16 barg (232 psig) from being exceeded.
1.9 personnel
Only authorized, competent and trained personnel are permitted to work on this product. This user guide is intended solely for such
personnel and is to be used only as a reference; it should not be used to replace conventional training.
1.10 safe handling

this product. Ensure that the equipment is depressurized and isolated prior to carrying out any of the scheduled maintenance
instructions specied within this user guide.
In no circumstances must a damaged product be used in operation.
Using damaged products can lead to irreparable functional faults or cause serious physical harm.
A suitable lifting aid must be used to minimize the
risk of physical injury or damage to the product.

2.7 site location
When selecting an installation site for the dryer, ensure the following conditions are met:
• Installation site should be located indoors on a at surface protected from the weather and other harmful conditions.
• The ambient temperature must not drop below 1°C (33.8°F) or exceed 50°C (122°F).
• The installation site should be level and able to support the weight of the product
• Ensure sufcient space around the product, to allow access for operation and maintenance.
• Take into account the noise generated by the dryer exhausting while in use when considering location.
IMPORTANT: It is essential that the system into which the dryer module is installed is tted with a pressure limiting/
relief device. This device should be installed between the compressor and the dryer module.

3.1 maintenance and servicing
Maintenance operations should only be carried
out by authorized, suitably trained personnel.
• Maintenance operation should only be conducted when the system has been shut down and fully depressurized.
• Isolate the dryer from the compressed air supply ensuring the system is in a safe condition for maintenance to be carried out.
• All gasket seals removed during maintenance operations must be replaced with new gaskets.
• All connections must be isolated and removed with care, paying particular attention to the areas that become pressurized.
• Do not modify or adjust the control settings.
• Only certied and approved replacement parts should be used.
• Always check all connections for leakage and secure seating.
• Ensure all loose parts are removed or secured to the dryer and it is in safe working condition before operation.
3.2 cleaning
Clean the equipment with a damp cloth only and avoid excessive moisture. If required a mild detergant may be used, however do not
use abrasives or solvents as these may cause damage.
3.3 daily checks
• Check the dryers for any external damage.
(assess and eliminate any defects found)
• Remove any loose dust or dirt from the dryer, clean all surfaces that appear to have attracted unwanted contaminants.
• Always check all connections for leakage and secure seating.
• Ensure all loose parts are removed or secured to the dryer before operation.
