in-plant requirements. All changes should be documented by plant personnel.
Table 5: Table of Scheduled Maintenance
Frequency Component Suggested Service
Weekly Mutator Shaft
Bearing
Lubricate each fitting with a handgun, approximately three shots.
Use a suitable NLGI Grade-2 bearing grease. (Not required for Extra Heavy Duty
Votator II.)
Shaft
Assembly
Remove shaft assembly at least once a week. Always use the removal trough skid
to avoid bottom blades scoring the heat transfer tube. Replace the mechanical seal
shell O-rings.
Product Tube Inspect the tube’s inner chrome surface to be sure it is smooth and bright. If rough
areas, marks or chrome plating deterioration exist, locate and correct the cause.
Replace the tube, if necessary.
Scraper Blades Examine scraper blades weekly, or after 40 operating hours. Based on amount of
wear, establish service frequency.
Maintain blades in good condition for longest machine life and best production
rates. Reserve a complete set of spare blades for routine replacement. Worn or
rough blades reduce heat transfer and can damage the heat transfer tube.
Jacket/
Accumulator
Purge gathered oil from accumulator section of accumulator jacket. If ammonia
charge is dumped from accumulator daily, oil is carried back with it.
Monthly Inlet and
Outlet Fittings
Replace O-rings on inlet and outlet fittings monthly, or more frequently as needed.
Gearmotor Check oil level and add as required.
Semi-
Annually
Refrigerant Inspect for oil and/or contaminants.
Flange O-rings Replace O-rings at least every 12-18 months.
