Consumables

Consumable parts are those

required to support the day-to-day operation of this equipment. We established

two types of consumables; those items that

must periodically be replaced to maintain performance (filters,

resin cartridges, etc.) and other items of limited life (fuses, etc.) that you can expect to replace on a more or

less random basis. Where practical, we recommend the frequency of replacement, or provides information on

life expectancy from which you may calculate a replacement interval compatible with your usage pattern.

The replacement of consumable parts is discussed in the

Maintenance and Servicing

section to assist you

in accomplishing your own service. Consumables may be ordered separately and in some cases, as an

expendables kit. Check with your customer service representative for additional information on the expend-

ables kit.
