Spectron spectropur LE 61 Instructions For Use

6. Operation and maintenance
6.1 Pressure regulators have always to be protected against damage
(visual inspections in regular intervals).
6.2 Pay attention to a perfect status of seals, sealing surfaces and pressure gauges.
!
6.3 In case of malfunctions, e. g. an increase in the outlet pressure during the supply, or
in case of leakage versus atmosphere or a defective pressure gauge, shut down the
upstream gas supply and take the pressure regulator out of operation.
7. Shut-down
7.1 For short-term interruption of work
Close the shut-off valve at the comsumer unit.
7.2 For longer interruptions or at the end of the work:
Close the gas cylinder valve and the shut-off valve at the consumer unit.
! 7.3 Before disassembly pay attention that pressure gauges and indicate zero.
8. Repair
8.1 Repairs may only be carried out in authorized workshops by expert persons.
8.2 Only original spare parts may be used.
type in each instance. So always specify the gas type.
8.3 In case of unauthorized repairs or use of non-original spare parts, any form of
liability for resulting damages will expire as well as the manufacturer's warranty.
8.4 After beeing repaired, the pressure regulator must be checked
proper function, leak-tightness and cleanliness of the gas-wetted surfaces.

1. Application
1.1 Designated use
Use the pressure regulator for gases dissolved under pressure, compressed or
liqufied gases. The pressure regulator LE 61, LE 71 and LE 81 reduce an inlet
pressure to an as constant as possible outlet pressure.
1.2 Non-designated use
!
Do not use the pressure regulator for gases in the liquid phase.
! Do not use the pressure regulator for unsuitable gas types or caustic gases.
