WARNING!
Do not operate the dryer until the instructions in this manual have been read and understood by
all personnel concerned.
When handling, installing or operating, personnel must employ safe engineering practices and observe all
related regulations, health and safety procedures, and legal requirements for safety.
Most accidents that occur during the operation and maintenance of machinery are the result of failure to
observe basic safety rules and procedures. Accidents can be avoided by recognising that any machinery
is potentially hazardous.
Sullair can not anticipate every possible circumstance which may represent a potential hazard.
The WARNINGS in this manual cover the most known potential hazards, but by definition cannot be all
inclusive. If the dryer user employs an operating procedure, item of equipment or a method of working
which is not specifically recommended by Sullair the user must ensure that the dryer will not be damaged
or made a potential hazard to persons or property.

PLEASE NOTE THAT YOUR WARRANTY MAY BE INVALIDATED IF THE EQUIPMENT HAS NOT
BEEN INSTALLED, COMMISSIONED AND MAINTAINED BY Sullair OR A Sullair APPROVED
AGENT.

INTRODUCTION
The SMC range of compressed air dryers are designed to remove moisture from
compressed air by utilising state of the art technology to obtain dewpoints of -40°F
PDP and by appropriate de-rating -100°F PDP.
SMC dryers have been designed to require minimal maintenance and can be installed
virtually anywhere.
The SMC dryer consists of upper and lower head assemblies joined together with an
aluminium extrusion containing twin internal chambers. The upper head assembly
contains inlet and outlet manifolds, pre-filter and autodrain. The lower head assembly
contains two exhaust valves and a passive shuttle ball valve. Contained in each
internal chamber is a combination desiccant / after-filter cartridge. During operation
one chamber is on-line (drying) while the other is regenerating, using the Pressure
Swing Adsorption (PSA) process.
Pressure Swing Adsorption (PSA)
A small percentage of dried air is taken from the dryer outlet flow and is used to
regenerate the saturated chamber by expanding the dried air from line pressure to
atmospheric pressure. During this process, the moisture is physically removed from
the regenerating chamber and vented to atmosphere through the exhaust.

2.0 INSTALLATION (refer to figure 1)
2.1 ESSENTIAL INFORMATION
Care must be taken to ensure that the dryer is not subject to flows (even peaks) in
excess of the dryers rated capacity, e.g. dryers downstream of an air receiver have
increased potential to be overflowed.
The dryer can be installed free standing, secured to the floor via the fastening points
provided in the base or secured to a wall using optional brackets.
The control enclosure (A) must be at the bottom and the dryer must be installed
vertical and level.
Two inlet and two outlet connections are available at the top of the dryer to enable
connection from either left or right. Unused connections (B) and (C) must be sealed
with the threaded plugs provided. Suitable rated pipe and connections must be used
for the installation. All pipework must be secure and safely positioned.
The purge flow is factory set for 87 psi g minimum operating pressure. Should the
minimum pressure requirement be different, the purge flow must be reset by a Sullair
engineer or a Sullair approved agent.
Ensure the dryer is electrically connected to a supply suitable for the unit. See wiring
diagram printed in 2.3 Electrical Details.
1. Filtration
A 0.01 micron pre-filter is contained within the upper head assembly. 1 micron after-
filters are integral within desiccant cartridges screwed into inserts in the upper head
assembly. Filters must be maintained by Sullair or a Sullair approved agent.
2. By-pass Line (D)
A by-pass line, 3/8" NPT (D) ensures complete safety during maintenance and
enables a continuous supply of compressed air to be maintained if required. It should
be remembered that air bypassing the dryer is dirty untreated air.
3. Valves (E, F, G)
Isolation valves, 3/8" NPT are recommended on the inlet (E), outlet (F) and bypass (G)
lines at the positions indicated in Figure 1.

2.3 ELECTRICAL DETAILS
Only competent qualified electricians must work on dryer circuitry.
Check the rating plate for power supply requirements.
Correct isolator switches must be provided at a safe and accessible point near to the
dryer.
The dryer must be provided with a live, neutral and earth.
Connect power to the dryer (via the conduit entry aperature *) at the fused terminal
block mounted on the small base plate located under the enclosure. Four screws
retain the base plate.
*For CE/BSP dryers, the conduit entry aperature is replaced by a mains cable gland

2.5 RUNNING THE DRYER WITH A MINIMUM PRESSURE BELOW 102 PSIG
If the dryer is to be run with a minimum pressure of 102psig (7 Bar g) an alteration to
the timer board is required.
To carry out the alteration,ensure the electrical supply is isolated, lie the dryer on its
back, to gain access to the control base. Remove the large plate to gain access to the
timer board. Move electric jumper from Position 1 to Position 2, as shown.
