3.3 INITIAL START-UP
Attention!
All pipes and wire connections must be tightened!
Furthermore, before start-up:

The pipes must be cleaned of scale , abraded material from the
threading, or other similar impurities.

All isolation valves upstream of the prefilter and downstream of the
afterfilter should be closed. The bypass valve (if installed) should be
open.

The ambient temperature must not be less than 33°F.
NOTE: Failure resulting from faulty installation or start-up does not fall under the
Sullair warranty obligation. Start-up by factory trained personnel is highly
recommended.
Perform the following tasks in sequence for the initial start-up:

Remove purge exhaust mufflers for the initial 1 to 2 hours of operation

Slowly open the inlet isolation valve and observe the pressure build-up on the
chamber pressure gauge of the adsorption dryer. Avoid an abrupt pressure build-
up as this may damage the dryer.

Turn the switch to the DRYER ON position.
NOTE: Do not switch to DDS ON during the first eight hours of operation.

The adsorption dryer must be powered approximately 3 to 4 hours with the
isolation valve downstream of the afterfilter closed.
This regenerates the
desiccant.

After the regeneration phase, open the shut-off valve behind the afterfilter slowly
while observing the chamber pressure gauge. If the shut-off valve is opened
abruptly, it could put a stress on the system. Close the bypass valve (if installed).
The adsorption dryer is now ready for operation and functions continuously and fully
automatically.
After eight hours of operation, it is appropriate to engage the DDS
feature:

Fully open the inlet valve to the sample cell

Partially open the discharge valve of the sample cell to bleed off a small amount
of sample air. Do not fully open discharge valve.
