Pentair HP 230 - Manual (Page 28)

MANDATORY BONDING TO POOL STEEL
(This is in addition to electrical ground)
Make sure that the unit cabinet is bonded to the pool steel.
Most codes require that the circulation pump be bonded
as well. You can connect at that point using at least a #6
gauge or larger solid copper wire. Use the external bond
lug on the cabinet to insure a good bond.
Bonding the unit to the pool steel will help reduce the
chance of electrolysis, also know as electrical corrosion.
A heater left un-bonded may experience corrosion to the
metal water tubing inside the heater.
