Preventive Maintenance Calendar
To keep the Jerome 631-X operating at peak performance, follow the maintenance schedule below

time, your requirements may be different from the listed schedule. Call AZI Customer Service at
800-528-7411, 602-470-1414, or e-mail support@azic.com for additional guidance for your
environment and operation.
