SECTION 2 PRODUCT USER MANUAL
15
1. Only authorized, trained and skilled engi-
neers should install the compressed air
dryer.
2. Safety devices, protecting covers or insula-
tions in the dryer are never to be removed or
modified. Each pressure vessel or accessory
installed outside the dryer with compressed
air (Any pressure above atmospheric pres-
sure) must be fitted with individual pressure
relief safety valves.
3. Install one (1) air by-pass valve and two (2)
switch off valves in the line to isolate the
dryer to allow easy maintenance and for pos-
sible isolation of the dryer without interrupt-
ing the compressed air flow.
4. In Line Filters: install one compressed air fil-
ter in line (particulate filter) before the dryer
to protect it against dirt and possible clog-
ging of heat exchanger. Install an After-filter
(coalescing filter) that can act as a backup
during short periods when the by-pass valve
is open to perform maintenance on the dryer.
Contact your Sullair representative/dealer for
suitable filters.
5. Water Filter: For dryers with water cooled
condensers, a water filter should be installed
in the supply water piping. (Water Cooled
Units Only)
6. The interconnecting piping must be of the
correct size, pressure rating and match that
of the dryer Inlet and Outlet pipe sizes. DO
NOT use pipes of lesser diameter as this will
lead to additional pressure loss and will
affect the performance of your air dryer. If
you are in doubt, contact your Sullair distrib-
utor. It is recommended to use the same pipe
size as that of the dryer Inlet and Outlet.
