Pentair HP 230 - Manual (Page 18)

The heat pump in equipped with
a internal "Automatic Bypass"
valve. A variable rate spring
valve is used to regulate the wa-
ter flow through the heat ex-
changer. Steady flow will be de-
livered over a wide range of flow
rates. This automatic valve can
handle a maximum flow rate of
90 gallons per minute.
The automatic valve will com-
pensate for flow loss due to nor-
mal filter debris accumulation or
changes if flow due to valving
and other conditions.
See chlorinator
placement guidelines.
