Feed Pump Setup Check
1.
Make sure one of the level sensor options “with
feed pump” is selected. See
Setup
on page 51.
2.
The Premier pump should go through 1 full cycle
(2 top changeovers) before the feed pumps start.
3.
Make sure the Feed Pump Time setting is set high
enough to fill the reservoirs before an alarm oc-
curs. See
Setup
on page 49.
4.
If both full and low level sensors are installed,
make sure the Feed Pump Time setting (
Setup
on
page 49) is set so the alarm for the full level sen-
sor will occur before the low level sensor alarm.
Base the settings on the Premier pump and the
feed pump capacity.
