Page 30: Parts List
Recommended Spare Parts Consumables: Consumable parts are those required to support the day-to-day operation of this equipment. Barnstead International establishes two types of consumables; those items that must be periodically replaced to maintain performance (filters, resin cartridges, etc.) and other items of limited service life (indicator lights, fuses, etc.) that you can expect to replace on a more or less random basis. - Page 31 Barnstead International recommends that you maintain a local stock of those parts listed under “General Maintenance” and “Safety Stock.” In the event of component failure, this safety stock can be drawn upon by you or Barnstead International technicians, thereby, avoiding unnecessary delays in delivery of replacement parts.
