4. Special Conditions for Safe Use
Sudden dynamic high-pressure inlet pressures should be avoided, and preferably be gradually
increased to protect against damage to the regulator.
5. Hazardous Location Usage
This equipment has not been manufactured specifically for use in potentially explosive
atmospheres and as such an ignition hazard assessment has not been carried out on this
product. If the user should wish to use this product in such an environment where there may
be a potentially explosive atmosphere then it is the responsibility of the user to conduct an
ignition hazard assessment against 99/92/EC.
6. Servicing and Maintenance
Servicing and maintenance work on the MF-414 regulators should only be performed after
fully reading and understanding the Operating and Servicing Manual. Due to the typical
nature of the gases the regulator can be used with, the operator should not endanger
himself/herself or others by working on this regulator without prior knowledge on the Health
and Safety concerns relating to handling of technical gases. Any uncertainty should be
clarified with Pressure Tech before working on the regulator.
Pressure Tech Ltd recommends the use of Krytox GPL 205 during servicing.
Prior to commencing service, please ensure that:
-
The equipment has been de-pressurised
-
The load spring has been de-compressed by turning the adjusting mechanism fully
anti-clockwise
-
Applications involving toxic, flammable or corrosive media have been fully purged
To ensure the best possible results from servicing, when re-assembling the regulator and any
assemblies within it, ensure that all areas of the components and the regulator body are
cleaned and free from contaminants which may result in failure of the regulator.
