Meter Calibration
Meter calibration is required upon installation, after disassembly, after significant wear, or
when dispensing a different viscosity fluid. Your FR902 series dispenser is factory calibrated
using mineral spirits. Calibration must be done between 6 and 40 GPM (23 and 151 LPM).
Meter calibration can be easily changed by following the calibration procedure. A container of
KNOWN
volume will be needed for the calibration procedure. For the FR902 Series
dispenser, a five gallon container or larger, or a 20 liter container or larger should be used.
Procedure for Meter Calibration
1.
For the most accurate calibration, install the
dispenser as it will be used. Dispense liquid
into a container of known volume.
2.
If calibration is required, turn off pump and
release any pressure in the system.
Remove seal screw to access calibration
screw (figure 2). If meter reads more than
was dispensed, turn calibration screw
counter-clockwise. If meter reads less than
was dispensed, turn the screw clockwise.
3.
Be sure to re-install the seal screw when
calibration is complete.
Operating Instructions
For accurate measurement and to prevent dispenser damage, dispenser and piping must
always be filled with liquid and be free of air. The meter portion of your dispenser should be
calibrated per instructions in this manual prior to its use.
1.
Reset register to “0”.
DO NOT RESET WHILE IN OPERATION!
Damage will result.
2.
Remove nozzle from holder and turn the power on by lifting the switch handle.
3.
Dispenser is ready for use. Insert nozzle into container to be filled and start flow of liquid.
Do not exceed 50 PSI of line pressure.
4.
When desired amount of liquid has been dispensed, stop the flow at the nozzle. Turn the
power off by pushing the switch handle down. Return the nozzle to its holder.
Maintenance
Your Fill-Rite FR902 series dispenser should operate virtually maintenance free. Certain
liquids, however, can dry out while in the meter housing, causing it to stop or perform poorly.
If this happens, dispenser should be thoroughly cleaned.
Cleaning Instructions
For a thorough cleaning, disassemble the dispenser per “ASSEMBLY / DISASSEMBLY”
section, “Dispenser Chamber Assembly” subsection. Rinse all components thoroughly.
Recalibrate dispenser following calibration instructions above.
IMPORTANT!
When returning a dispenser for service, it must be triple rinsed
and accompanied by a note stating what chemicals have been pumped through
it. Dispensers not adhering to these specifications may be refused for service.
