1. General information
All persons involved with the assembly, operation and/or maintenance of pressure reducer HON 219 must
read and understand all of the following documents:
- Technical product information 219.00 - it contains the equipment's technical data and dimensions as well
as instructions concerning set-up 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 219.20 – this document contains more detailed
information on assembly and operation of pressure reducer HON 219.
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 rst instance. However, in the
mid-term, intervals must be adapted to the requirements of each specic 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 specically recommended in the Honeywell
operating and maintenance instructions for spare parts.
In the event spare/wear parts and/or lubricants & oils other than those specically 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 specic 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.

2. Specic operating instructions
2.1 Changing setpoints
Increase the setpoint by turning the setpoint adjusting screw. Having changed the setpoint of the
control stage, be sure to secure the setpoint adjuster using at head screw (213, 313) or nut (3).
Be sure to adjust the connection between lever and lever eye to the central position.
Find the central position by test-turning the diaphragm all the way to the stops on the left and on the right.

Note
Safety relief valve does not allow the setpoint to be changed.
The following setpoints have been pre-set:
– 5 bar approx. – for measuring units M, G, GS, F
– 10 bar approx. – for measuring unit V
Danger
Replacing distance piece (23)
Do not dismount inlet connection piece (23, 59).
When installing the pressure reducer on a pipework system and when removing it, be sure
to use an SW wrench to secure inlet connection piece (23, 59) and outlet connection piece
(33) so they don't move and/or come loose.
When replacing jet connecting piece (23) and/or distance piece with jet and piston guide
(28), be sure to observe proper piston mounting position.
See also “Mounting and dismounting sealing shim (29)”.
Mounting and dismounting sealing shim (29)
When dismounting piston and seal (29): Do not start to unscrew jet connecting piece (59)
and/or distance piece with jet and piston guide (23, 27, 28) before you have dismounted
cap (4) from body (18).
When mounting piston and seal (29): always mount together with jet connecting piece
(59) and/or distance piece with jet and piston guide (23, 27, 28) while diaphragm (10) and
cap (4) are still o. Be sure to nd the correct mounting position of the piston inside the
jet.
