Automatic Drains should be used where the filter location may make servicing difficult, where filters may be hidden from view and consequently overlooked, or where equipment is in continual use. Areas where large quantities of liquid may accumulate over a short period of time should be equipped with an auto-drain.

  2. Remove manual drain assembly from bowl. Be careful not to scratch or damage the inside surfaces of the bowl.
