DISPENSMAN ®
Chapter 2
SAFETY & USER PRECAUTIONS
General Safety Precautions
In order to put the instrument into operation as quickly as possible and free from
defects, it is necessary that you read this manual carefully before using this
instrument.
Highest safety precautions should be used when dispensing corrosive,
poisonous, radioactive, or hazardous chemicals.
• Observe the general safety regulations for handling chemicals (e.g.,
protective clothing, protective goggles).
• Use DISPENSMAN only with regard to the chemical resistance of materials
and for the purpose for which is intended (see the chemical compatibility
list, pages 17 and 18).
• Always check the instrument for leak tightness and a firm position of the
plug and socket connection before you use it.
• Never use force. Breakage of any part will lead to hazardous exposure for the
user as well as for other persons.
• Clean the instrument every week and if you want to use DISPENSMAN for
another chemical solution or if you do not use it for a longer time.
• The temperature of the dispenser and reagent should not exceed 40°C (104°F).
• The user is responsible for checking that the instrument is suitable for his
application.
• The proper and secure function is only guaranteed by using the supplied
discharge tube 9 . Do not use any other discharge tube.
• Never use damaged or deformed tubes. If the valve is damaged, the
discharge tube might drop.
• The discharge tube should never face the user and a collection vessel should
be placed underneath.
• Check all fittings for tightness approximately one hour after assembly or
disassembly as temperature variations may cause material expansion, which
can cause leakages.
• If you are unsure about dispensing a specific chemical solution, refer to the
chemical compatibility list in pages 17 and 18 or contact your local Gilson
representative.
Safety Considerations Before Initial Operation
• Check instrument for damage caused in transit.
• The telescopic tube
21
should reach the bottom of the bottle.
• Do not use the outer housing
3
for carrying the assembled dispenser. If you
need to carry the instrument, hold it by the base of the instrument.
• Attach discharge tube
9
and clip on protective sleeve
8
carefully to avoid
damage.
• When screwing on/off the bottle do not hold the instrument at its outer
housing
3
, but at the screw base.
• Do not pump before the instrument has been assembled completely and a
collecting vessel has been placed underneath.
Operating Limitations
Do not use for:
• PTFE swelling solvents
• Hydrofluoric acid
• Chemical solutions that react with platinum-iridium alloys
Liquids used with DISPENSMAN must not exceed the following limits:
