zontal or vertical. Anodes should be inspected periodically * and replaced

anode varies with water quality and PH.
* Zinc anodes should be inspected every twelve (12) months. Magnesium
anodes, which are consumed at a faster rate, should be inspected ever three (3)
or four (4) months.
2A.2 AUXILIARY COOLING
For pumps not equipped with standard gearbox cooling, a cooler option is
available to protect the gearbox, the apparatus engine, and the pump. The
gearbox cooler circulates pump water to transfer heat from the gearbox oil
to the pump discharge, thus maintaining proper operating temperatures.
