SB-13 Flow Meter Check and Replacement
Model: PT-200FT
Software version: All
Tools required: 2 adjustable wrenches or slip joint pliers
Phillips screw driver
Process:
Check Operation
1. Lock the dish machine into the rinse mode.
2. Turn the power to the PT-200 on.
3. Check for a plumbing bypass (if there is, make sure it is closed to assure flow of
rinse water through the booster.)
4. Watch the flashing green LED on the green control board. Once you see a
pause, start counting the green flashes until the next pause. Verify the count
twice.
5. Divide the number of flashes between pauses by 3. This resulting number will be
the flow rate in gallons per minute. Example - 15 flashes between pauses
divided by 3 = 5 GPM.
6. If you do not see a pause in the green LED with the rinse running, the flow meter
is not sensing flow or no water is passing through booster or you have a
recirculating booster heater (See PT-200RC troubleshooting diagram).
Adjustment or Replacement
1. Be sure the pick-up wire on top of flow meter (2354) is tight.
2. Check flow meter connector to control board.
3. Replace flow meter by the following procedure:
a. Turn off water at shut off valve outside of booster.
b. Remove 4 Phillips screws from side access panel (digital display) &
let panel hang from side. Take care not to damage digital display
wiring.
c. Ensure that the water in the pipe is cool. Using 2 wrenches or slip
joint pliers loosen the union nuts on either side of the flow meter and
remove the flow meter and gaskets (2354 Flowmeter only).
d. Verifying flow direction, install new meter with 2 new gaskets (2354
Flowmeter only) and tighten union nuts (do not over tighten 3226
Flowmeter union nuts).
e. Replace access panel.
f. Test
