Spectron Spectrocem FE 121 Instructions For Use

5.2 Pressure regulators have always to be protected against damage (visual
inspection at regular intervals).
!
5.3 The adjustment of the relief valve (4) must not be altered!
5.4 Ensure perfect condition of seals, sealing surfaces and pressure gauges.
5.5 In case of malfunctions, e. g. an increase of the outlet pressure during the
!
supply, or in case of leakage versus atmosphere or a defect pressure gauge, shut
down the upstream gas supply and take the pressure regulator out of operation.

6. Shut-down

! 6.1 For longer interruptions or end of work:
Close the gas cylinder valve (1) first by releasing the hand knob (6) to
depressurize the cylinder pressure regulator.
6.2 Before disassembly purge the regulator (where applicable) and make sure that
pressure gauges (3) and (5) display zero pressure.

7. Repair

7.1 Repairs may only be carried out
persons.
7.2 Only original spare parts must be used. The materials have been adapted to the
gas type in each instance. So always specifiy the gas type
7.3 In case of independent repairs, the use of non-original spare parts or changes on
the side of the user or a third party without the approval of the manufacturer,
any form of liability for resulting damages will expire as well as the
manufacturers warranty.
7.4 After being repaired, the pressure regulator must be checked with respect to
proper function, leak-tightness and cleanliness of the gas-wetted surfaces.When
the system is used again, a sufficient purging operation must be carried out first.

1. Application
1.1 Designated use
Use with pressure gas cylinders for compressed high purity gases, gases dissolved
under pressure and liquid gases to reduce the cylinder pressure and maintain an as
constant as possible outlet pressure.
1.2 Non-designated use
!
Do not use pressure regulator for gases in the liquid phase.
! Do not use for unsuitable gas types.
Do not use pressure regulator in operating conditions, that it was not designed for.
!
Do not use at temperatures below -30°C or above +60°C.
