Under normal conditions, drain the bearing hous­
ing once each year and refill with approximately 11
ounces (0,3 liter) clean oil. Change the oil more fre­
quently if the pump is operated continuously or in­
stalled in an environment with rapid temperature
change.
Monitor the condition of the bearing lubri­
cant regularly for evidence of rust or mois­
ture condensation. This is especially im­
portant in areas where variable hot and
cold temperatures are common.
For cold weather operation, consult the factory or a
lubricant supplier for the recommended grade of
oil.
