2.4 SAFETY REGULATIONS
2.4.1 IMPORTANT SAFETY NOTES:
1. When operating the air dryer the operator
must employ safe working methods and
observe all recommended/local safety
instructions and applicable regulations.
2. Prior to installation, the dryer and the com-
pressed air system must be depressurized
and disconnected from the electrical main
supply.
3. The user is responsible for safe operating
conditions. Parts and accessories must be
replaced if inspection shows that safe opera-
tion cannot be assured.
4. Installation, operation, maintenance and
repair are to be performed only by autho-
rized, trained and certified technicians.
5. DO NOT exceed the minimum and maximum
values of all the parameters mentioned on
the Main data label, Electrical data label and
accompanying specification sheets if any.
6. All safety precautions mentioned in this
manual must be adhered to at all times and
by all personnel working on the dryer
2.4.2 TRANSPORTATION
1. Use care and caution when transporting the
dryer. Avoid sudden jerks, tilting, dropping
and other physical abuse.
2. A forklift can be used to transport the dryer
provided the forks are long enough to sup-
port the full width or length. Caution must be
used throughout the move.
2.4.3 POSITIONING
1. The dryer must be installed horizontally. A
minimum of at least 1 ½ feet clearance
around the dryer is necessary to allow free
air circulation and easy access for servicing.
2. The ambient temperature in the room
should not exceed 120° F and should not
be below 40° F, taking into account the
heat radiated by the dryer. (About 18 watts
for each SCFM under ISO 7183-5 condition
or 40 watt for each liter/sec under ISO 7183-
A condition).
2.4.4 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. Optional air by-pass valve: Install one (1) air
by-pass valve and two (2) switch off valves in
the line before the dryer to allow easy main-
tenance and for possible isolation of the
dryer without interrupting the compressed air
flow.
4. In Line Filter: install one compressed air filter
in line before the dryer to protect it against
dirt and possible clogging of heat exchanger.
Contact your Sullair representative/dealer for
suitable filter.
2.4.5 STEPS TO UNDERTAKE BEFORE
OPERATING
1. Read this manual completely.
2. Review all safety precautions.
3. Use recommended pipe sizes as per specifi-
cations.
4. Never operate the dryer at pressures above
the maximum specified on the dryer label
(check the technical specifications).
