Notes:
Other manufacturer's controls providing similar function may be used, if properly 1.
located and selected.
Use low water cut-off function only. Pump controller function must only be handled 2.
by the primary control.
When pump control is used with feedwater tank, install pump control on boiler and 3.
make-up water feeder on tank. Use separate low water cutoff on boiler when back-
up is needed. Do not install combination low water cutoff and feeder as back-up
control on boiler. Feeder will operate before pump control operates.
