NOTE
Paraffin oil is bright and transparent in appearance. A slight discolouration, caused by
the running-in process of new mechanical seals or small amounts of leakage from the
fluid handled, has no detrimental effect. However, if the coolant is severely contaminated
by the fluid handled, this will suggest a defect on the mechanical seals.
1. Position the pump set as illustrated.
