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.
