General information
All persons involved with the assembly, operation and / or maintenance of the gas mixer
HON 985B -140/65-ZW-N-NI must attentively read and understand these operating and
maintenance instructions in their entirety.
Inspection and maintenance intervals depend mostly on the operating conditions at the respective
system. Amongst other factors, the device used and the corresponding gas composition, and the
existing gas contamination as well as any accumulating condensates must be taken into account.
There are no general rules or recommendations for intervals. Therefore, it is advisable to include the
devices in the gas engine maintenance intervals.
If operational irregularities are discovered during the operation or during a functional
test, unplanned maintenance work on the mixer is required. This must be performed
Note
as soon as possible after the discovery of the deviation in operating behaviour.
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.
The check must include in particular seals, all moving parts such as the transmission thread and
Venturi insert. 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. In the event spare / wear parts and/or lubricants & oils other
than those specifically recommended are used, Honeywell shall not be held liable for any defects and
consecutive damages attributable to such use of illegal parts, lubricants, oils etc.
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.
