leakage. Battery terminals should be
kept clean, tightly connected, greased
and protected from accidental short
circuiting. Refer to separate instructions
in the Owner’s manuals including wiring
diagrams.
E. PLUMBING SYSTEMS
All pumps and oat switches should be
checked frequently to ensure proper
operation.This isan especially important

H. ELECTROLYSIS AND GALVANIC
PROTECTION
Saltwaterallowselectriccurrenttoowfrom
anodic to cathodic materials. The relative
positionoftwometalsontheGalvanictable
determines which material (the Anode) will
lose material and which will remain largely
unchanged(theCathode).
