1. General information
All persons involved with the assembly, operation and/or maintenance of the HON 372 gas pressure regulator must read and
understand all of the following documents:
-
Technical product information 372.00
— this Honeywell document contains the technical data and dimensions of the
equipment as well as instructions concerning construction and mode of operation.
-
General operating manual for gas pressure regulators and safety devices
– this Honeywell document contains information
on assembly and operation as well as general information on troubleshooting.
- Operating and maintenance instructions/spare parts 372.20
– this Honeywell document contains more detailed information
on assembly and operation of the gas pressure regulator.
There are national laws and regulations for all sorts of jobs on gas pressure governors, from planning to maintenance. Be sure to
comply. (In Germany, for instance, DVGW work sheets G 600, G 459/II, G 491 and G 495.)
Inspection and maintenance intervals depend mostly on operating conditions and the nature and properties of the gas. There
are no general rules or recommendations for intervals. For Germany, we recommend to consider maintenance intervals as
stated in DVGW work sheet G 495 in a first instance. However, in the mid-term, intervals must be adapted to the requirements of
each specific equipment.
During maintenance, components must be cleaned and then checked thoroughly. This is necessary even if there have not been
any unusual observations during operation and/or functional testing. Checks must focus, in particular, on diaphragms and seals
and all movable parts and their respective bearings. Any and all defective parts must be replaced with new ones. The same
applies to
O rings removed during disassembly.
Do not use any spare/wear parts and/or oils & lubricants not specifically recommended in the Honeywell operating and
maintenance instructions for spare parts.
In the event spare/wear parts and/or lubricants & oils other than those specifically recommended are used, Honeywell shall not
be liable for any defects and/or consecutive damages attributable to such use of illegal parts, lubricants, oils etc.
Item numbers mentioned in the specific operating and maintenance instructions correspond with the numbers in the spare
parts lists and drawings.
Some parts in the lists and drawings are marked with a letter
"W"
. We recommend to always have a reserve of those parts in
stock for maintenance purposes. Those spare parts are put together in another separate list at the end of the spare parts list.
