Owner's Guide
The following procedure will operate the pump. This is useful to verify that the pump is operating prop-
erly and to check the water flow rate.
This operation runs the pump and fire the water heater each time the “PUMP” button is pushed to mini-
mize energy consumption. The pump runs until water temperature at the thermistor inside the water
heater reaches 102 °F (38.9 °C) or the water temperature at the thermistor rises 10 °F (5.6 °C) above the
initial temperature of the water. The pump runs for five minutes at the longest. No. 5 DIP switch of the
lower bank needs to be changed to "ON" position in the operation.
Note: The pump timer is not available when the No. 5 DIP swtch of the lower bank is set to "ON".
