1 Safety precautions
1.1 Safety icons
Danger: Indicates an imminently hazardous situation which, if not avoided, will result in
death or serious injury.
Warning: Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
Notice: Indicates a potential situation which, if not avoided, might result in property damage
or in an undesirable result or state.
Note: Indicates important information.
1.2 General safety precautions
Danger: The condensate drain is under pressure. Suddenly escaping compressed air may
result in serious injuries. Do not carry out mechanical or electrical work on the condensate
drain as long as the condensate drain is under pressure.
Danger: Touching live parts might result in serious injury or death.
Danger: There is a risk of leakage of condensate into the environment. Water spots on the
floor may be very slippery and result in serious fall injury. Water spots should be properly
removed from the floor immediately.
Danger: Exceeding the maximum allowable operating conditions may result in serious injury
or death. It is the duty of the operator to ensure that the operating pressure and temperature
fall within the values provided by the condensate drain; these values are indicated on the
identification plate.
Danger: Damages of the condensate drain may lead to unpredictable hazardous situations.
Operating a damaged condensate drain may result in serious injury or death. Never start or
operate a damaged condensate drain.
Danger: The condensate drain components are not designed to withstand any external
overloads; the condensate drain may burst due to additional pressure. Any bursts of
pressurized components may cause serious injuries and/or death. Transmission of loads or
stress into the connections of the condensate drain is not permissible.
Warning: All responsibility for any damage or injury resulting from neglecting these
precautions, or non-observance of the normal caution and care required for installation,
operation, maintenance and repair, even if not expressly stated, will be disclaimed by the
manufacturer.
• Read the instruction book carefully.
• The operator must employ safe working practices and observe all related local work safety
requirements and regulations.
• If any of the following statements does not comply with local legislation, the stricter of the two
shall apply.
Instruction book
4 2920 7213 30
• Installation, operation, maintenance and repair work must only be performed by authorised,
trained, specialised personnel.
• Before carrying out any maintenance, repair work, adjustment or any other non-routine checks,
stop the device. In addition, the power isolating switch must be opened and locked.
1.3 Safety precautions during installation
• The use of personal protection equipment (P.P.E.) during installation and maintenance
operations is recommended.
• Install the equipment where the ambient air is cool and as clean as possible. Consult section
Reference conditions and limitations.
• During installation or any other intervention on the equipment or one of the connected
machines, the machines must be stopped, de-energized and the isolating switch opened 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 start equipment.
• Install the equipment in an area free of flammable fumes, vapours and particles, e.g. paint
solvents, that can lead to internal fire or explosion.
• The electrical connections must correspond to the applicable codes. The equipment must be
earthed and protected against short circuits by fuses in all phases. A lockable power isolating
switch must be installed near the equipment.
• For machines controlled by a central control system, a sign stating "This machine may start
without warning" must be affixed near the instrument panel.
• In multiple compressor systems, manual valves must be installed to isolate each compressor.
Non-return valves (check valves) must not be relied upon for isolating pressure systems.
• Never remove or tamper with the safety devices.
• If the maximum pressure of the compressor is higher than the design pressure of the connected
equipment (e.g. a nitrogen generator or an oxygen generator), a full flow safety valve must be
installed between the compressor and the connected equipment, in order to be able to blow off
the excessive pressure.
• Only use pressure-proof installation material. The feed line must be firmly fixed. The discharge
line should be a short pressure hose or a pressure-proof pipe. Ensure that the condensate
cannot squirt onto persons or objects.
• Avoid excessive tightening of the connectors on the inlet and outlet. When tightening the
connectors, two keys have to be used: one to hold the valve, the other to tighten the nut.
• In areas where freezing temperatures are expected, the device should be provided with
thermostatically controlled heating (optional equipment).
• During electric installation, all regulations in force need to be adhered to (e.g. VDE 0100 / IEC
60364).
Note: Also consult following safety precautions: Safety precautions during operation and
Safety precautions during maintenance or repair.
Note: The precautions apply to electrical devices.
Note: For precautions applying to the connected equipment, consult the relevant instruction
book.
Note: Some precautions are general and cover several machine types and equipment;
hence some statements may not apply to your device.
