1. General

1.1 General information

All persons involved with the assembly, operation and/or maintenance of the gas mixer HON 985A -100/50-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 type of gas 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 immediately

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 parts with transmission thread and the venturi insert. Any and all defective

parts must be replaced with new ones. The same applies to o-rings removed during dismantling.

Do not use any spare/wear parts and/or oils & lubricants not specifically recommended in the Honeywell operating and

aintenance instructions. In the event spare/wear parts and/or oils & lubricants other than those specifically

recommended are used, Honeywell shall not be held liable for any defects and/or 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 a separate table at the end of the

spare parts list.
