PRINCIPLE OF OPERATION SECTION 5
22
5.7 INSTALLATION
In addition to the general mechanical construction
procedures and local regulations, the following
instructions need to be emphasized:
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 acces-
sory installed outside the dryer with com-
pressed air (Any pressure above
atmospheric pressure) must be fitted with
individual pressure relief safety valves.
3. Need to add electrical specifications. Such
as wire size, fuse size, breaker sizing, spec-
ify which models are single phase and which
models are three phase.
4. Install one (1) air by-pass valve and two (2)
switch off valves in the line before the dryer
to allow easy maintenance and for possible
isolation of the dryer without interrupting the
compressed air flow.
5. 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.
6. Water Filter: For dryers with water cooled
condensers, a water filter should be installed
in the supply water piping. (Water Cooled
Units Only)
7. The interconnecting piping must be of the
correct size 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 distributor. It is recommended to
use the same pipe size as that of the dryer
Inlet and Outlet.
S
TEPS TO UNDERTAKE BEFORE OPERATING
1. Read this manual completely.
2. Review all safety precautions.
3. Use recommended pipe sizes as per specifi-
cations.
4. DO NOT operate the dryer at pressures
above the maximum specified on the dryer
label (check the technical specifications).
5. DO NOT operate the dryer in temperatures
above 120°F (50°C) degrees
6. DO NOT operate the dryer with inlet air tem-
peratures above 150°F (65°C)
