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.
