Water Quality Settings on the DewPoint Machine
It is critical that water quality settings in the DewPoint control system are set up correctly.
Failure to do so may result in poor water quality conditions in the boiler. Poor boiler water
quality can cause water carry-over into hay during the baling process, which will damage the
hay and may create a risk of stack fires.
● Obtain water test and recommendations report for your operation.
□
Your water samples should have been processed and the report should be available from your
dealer.
●
ENTER
water quality settings based on water test and recommendations report.
□
SWITCH DewPoint touch screen “ON” with lighted rocker switch on the lower right side of the
touch-screen enclosure.
□ When the computer has initialized, follow on-screen instructions and PRESS “Continue” button.
□ Select “Menu” → “Settings” → “
Water Quality”.
□ Enter location name and water PPM for each tested water source.
● SELECT the water source you will be using for the next operation.
□ Whenever a different water supply source is used please select that water source from the “
Water
Quality” screen.
Water Quality/Blow-Down Principles
●
Boiler Blow-Down.
□ Boiler water quality maintenance is critical in maintaining the health and longevity of your boiler
system. Proper blow-down settings and procedures are a critical element in maintaining boiler
water quality.
□
Blow-down frequency and volume.
•
Frequency of blowdown is dependent upon your water quality test.
•
Water tests prior to the use of the DewPoint machine provide the information you need to
enter in the water quality screen for an appropriate blow-down schedule.
•
If you notice water carryover or “foaming” during field operation you should check your supply
water source to be sure your water treatment is working properly. You may also need change
the settings in the
water quality screen.
•
“Foaming” or water “carry-over” occurs because of high surface tension on the surface of the
boiler water. It is the same reaction that occurs when a pan of spaghetti noodles cooking on the
stove boils over. Surface tension is increased because of high concentrations of contaminants
left behind in the boiler water as steam is produced and discharged from the boiler during field
operation.
•
The blow-down process removes some of the contaminated water in a controlled manner and
allows new clean supply water to replace the old.
