NOTE:
Before starting any maintenance activities, make sure that the supply power is shut OFF.
7 .1 Wash-down recommendations
• Cleaning should only be done by qualified personnel.
• Tolomatic requires the actuator to be stationary and de-energized during cleaning.
• It is recommended that the actuator be fully retracted during cleaning.
• Follow IP69K wash-down standards for pressure, proximity and temperature. Violating the
IP69K standards could be detrimental to the life of the actuator.
• Tolomatic prohibits the use of friction style cleaning such as a wire brush. Wash-down and
wipe down cleaning are the only approved cleaning methods.
• Minimum acceptable concentrations of cleaning chemicals should be used to successfully
sanitize equipment. Consult Tolomatic for chemical compatibility.
• A rinse down of the actuator is required after the cleaning process to minimize seal exposure
to sanitizing chemicals.
7 .2 Seal replacement recommendations
7 .2 .1 General Application Scenario
• One wash-down per day following wash-down guidelines above.
• Actuator is not experiencing side load during operation.
• Thrust rod is not being contaminated by food product or other materials during operation.
• Hardware is not damaged and is still in operating condition.
• Maximum velocity and acceleration limits are not exceeded.
• Actuator is operating within specified temperature range.
7 .2 .2 Recommendation
• Seals should be replaced every 25 million inches of travel. Customer testing or experience
can prolong seal replacement interval.
7 .2 .3 Early Replacement Recommendations
• 50% reduction in seal replacement interval if food product is expected to be present on
thrust rod during operation.
• 50% reduction in seal replacement interval if wash-down frequency is 3+ time per day.
