Spectra Watermakers Bimini 300, Installation And Operating Manual

Page: 31 / 78

31
Adjustments for your Bimini 300 are typically calibrated from the factory to ensure that sea wa-
ter is thoroughly flushed out of the watermaker using the least amount of fresh water.
However, due to different lengths of hose runs, different rates of flow, and different pressures in
shipboard fresh water systems, the flush duration should be optimized for your boat. The flush
cycle is adjusted with 2 settings: the pump speed and the flush duration.
Check the pump speed
1. Close the thru - hull for the raw water inlet.
2. Push the Fresh Water Flush button. The flush valve will open and the feed pump will start at
Flush Speed. If the flush completes normally, then the Flush Cycle is set properly.
3. If the display alarms ‘ Service Prefilters ’ then the fresh water pump is not supplying enough
water, and the feed pump needs to be slowed down.
Slowing down the pump during a Fresh Water Flush
You can slow down the feed pump from the Spectra Connect Display ’ s Dealer Access Settings.
Logging into the Dealer Access Settings is outlined in the Spectra Connect Programming section
of the manual,
Once in the Dealer Access settings navigate the screens as follows:
Bring down the Fresh Water Flush down 0.5 (for example from 2.9 to 2.4) and preform another
test. If you still get the alarm repeat this process until the Bimini flush speed matches that of
your fresh water system and you no longer are received an alarm.
Once you ’ ve adjusted the speed correctly, the speed controller will stay programmed for this
speed during fresh water flushes.
