Safety Precautions During Operation - BeaconMedaes HTM Instruction Book

6. Portable and mobile RF communications equipment can affect the unit. They should be used
no closer to any part of the unit, including cables, than the recommended separation distance
calculated from the equation applicable to the frequency of the transmitter (See EN 60601).
7. No external force may be exerted on the inlet and outlet piping. The connections must be free
of strain.
8. If remote control is installed, the machine must bear a clear sign stating "Danger: This machine
is remotely controlled and may start without warning".
The operator has to make sure that the machine is stopped and that the isolating switch is open
and locked before any maintenance or repair. As a further safeguard, persons switching on
remotely controlled machines shall take adequate precautions to ensure that there is no one
checking or working on the machine. To this end, a suitable notice shall be affixed to the
starting equipment.
9. Air-cooled machines must be installed in such a way that an adequate flow of cooling air is
available and that the exhausted cooling air does not recirculate to the inlet.
10. The electrical connections must be made in accordance with the applicable codes. The
machines must be earthed and protected against short circuits by fuses in all phases. A lockable
power isolating switch must be installed near the equipment.
11. On machines with automatic start-stop system or if the automatic restart function after voltage
failure is activated, a sign stating "This machine may start without warning" must be affixed
near the instrument panel.
12. Never remove or tamper with the safety devices, guards or insulation fitted on the machine.
Every pressure vessel or auxiliary installed outside the machine to contain air above
atmospheric pressure must be protected by a pressure-relieving device or devices as
required.
13. Piping or other parts with a temperature in excess of 80˚C (176˚F) and which may be accidentally
touched by personnel during normal operation must be guarded or insulated. Other high-
temperature piping must be clearly marked.
14. For water-cooled machines, the cooling water system installed outside the machine has to be
protected by a safety device with set pressure according to the maximum cooling water inlet
pressure.
15. If no safety valve is present in the air net close to the desiccant dryer (e.g. safety valve of
compressor), full flow safety valves must be installed on the dryer vessels.
16. If the maximum pressure of the compressor is higher than the design pressure of the dryer, a
full flow safety valve must be installed between the compressor and the dryer in order to blow
off the excessive pressure in case the safety valve of the dryer should be out of order or blocked.

Safety precautions during operation

1. Always be careful when touching any piping or components of the dryer during operation.
2. Use only the correct type and size of hose end fittings and connections. When blowing through
a hose or air line, ensure that the open end is held securely. A free end will whip and may cause
injury. Make sure that a hose is fully depressurized before disconnecting it.
3. Persons switching on remotely controlled machines shall take adequate precautions to ensure
that there is no one checking or working on the machine. To this end, a suitable notice shall be
affixed to the remote start equipment.

These precautions apply to machinery processing or consuming air or
inert gas. Processing of any other gas requires additional safety
precautions typical to the application which are not included herein.
Some precautions are general and cover several machine types and
equipment; hence some statements may not apply to your equipment.
