FOREWORD
The compressed air dryer systems have been designed and manufactured to ensure that maximum
safety and performance is achieved. It is expected that users of these systems will employ safe
working practices and ensure that when installing, commissioning, operating or maintaining the
equipment, any legal requirements are fulfilled. For example, in the UK, users should refer to the
Health and Safety Act, 1974.
All ancillary equipment such as pipework, valves, fittings etc., must be suitable for the pressures and
capacities involved.
Replacement parts are available from your distributor or the manufacturers ( see back page for
information). The adoption of a regular servicing policy is strongly recommended and will result in
ensuring that a high performance is achieved. Serial numbers and customer order numbers should
be referred to in any communication. (Serial numbers can be found on the identification plate
attached to the dryer). The figure number and the appropriate diagram in this manual and the item
number (shown in circle,) will also assist in part identification.
Any warranty will be invalidated if the dryer is not installed in accordance with the manufacturers
recommendations or non-approved parts substituted. Substitute parts could reduce the performance
or service life in addition to creating potential hazards.
The manufacturers reserve the right to modify the contents of this manual without notice. The data
given is a guideline to users and in no way binding on the manufacturers.
BEFORE SERVICING OR DISMANTLING ALL PRESSURE MUST BE RELEASED
FROM THE SYSTEM AND ITS ASSOCIATED PIPEWORK AND ANY ELECTRICAL
SUPPLY ISOLATED.

RECOMMENDED ROUTINE MAINTENANCE
Weekly
1. Ensure drain function / operation on all filters.
2. Ensure the change-over occures approximately every 2 mins.
3. Check all gaskets, control valves, pipes and fittings for air leaks.
4. Ensure moisture indicator paper is blue.
Inlet / Outlet elements should be changed every 6000 / 8000 hrs.

OUTLET HEAD ASSEMBLY SECTION A1
A1.1 UPPER GASKET REPLACEMENT
Disconnect outlet pipework. Remove head bolts, lift head clear.
A1.2 MOISTURE INDICATOR REMOVAL
Remove two screws from sight glass. Change indicator paper and refit, ensuring gasket is in
good condition and the air holes are clear.
A1.3 CHECK VALVE REPLACEMENT
Remove outlet head as above. Remove circlip and valve seat with o-ring. Remove check
valve.
SAR065 - SAR 088
Check the valve is accesible when the head and purge plate are removed. Valve discs can be
changed by securing the valve stem and removing the retaining nut. Valve guides can be
removed by unscrewing from the head.
For re-assembly, follow the reverse procedure always fitting new gaskets.

GENERAL
A1.4 ADJUSTMENT OF VARIABLE PURGE
The variable purge needle valves are situated in the top or rear of the outlet head on the dryer.
NOTE:
The dryer purge needle valves are factory set for 20% of rated flow of the dryer at 7
barg (102 psig) inlet pressure (18% actual @ 6 barg) The purge needle valves only
require adjustment if the inlet pressure to the dryer is not 7 bar g (102 psig).

Turn both valve adjusting screws clockwise until they are fully closed .
DO NOT OVER TIGHTEN THESE SCREWS.
The 4mm or 6mm plastic pipe which connects both valves together should be removed
from the push in connections on the valves by pressing on the face of the connection to
release the collet.
A flow meter (not supplied) which is capable of measuring the amount of purge air
required should be fitted to either one of the purge needle valves.
Allow the column, on which the purge needle valve functions to pressurise. Turn the
adjusting screw in an anticlockwise direction until the desired purge flow setting is
obtained. If the flow meter does not register after THREE TURNS, the adjacent
column is pressurising, wait for the desired column to pressurise and continue.
The operating pressure must be maintained throughout in order for the purge flow
setting to be correct.
When the above operation is complete and the correct purge flow is obtained, wait until
the adjacent column pressurises. Remove the flow meter from the previously adjusted
valve and attach to the unadjusted valve. Turn the adjusting screw anticlockwise until
the desired purge flow setting is obtained.
After adjustment has been carried out, remove the flow meter from the previously
adjusted valve. Replace the 4mm or 6mm plastic pipe. A proportionate amount of
purge air will exhaust when this pipe is being fitted, relative to the capacity of the
dryer.
The correctly adjusted unit is now ready for use. For settings other than 7 bar g, consult
the manufacturer.
NOTE: The maximum rated capacity of the flow meter as recommended by the
manufacturers instructions should be checked before use.
