3.4 Chemflo Flow Rates
The flow rate of the
Chemflo
is varied using a duty cycle, so for most of the time the pump does
not operate. For example, the pump will be ON for 2.5 minutes per 15 minute cycle when it is set to
99. When the unit is set to 50, the pump will be ON for half the time, i.e. 1.25 minutes per 15
minute cycle. Refer to the table below.
The only time that the pump operates continuously is when the control is set to FULL.
