to the nozzle, if present. Installation to metal con –
nections is not recommended. Install as follows:
- If necessary, remove nozzle from hose.

- If necessary, attach nozzle to meter.
- Hand tighten the meter at the housing ends.Do not use a wrench or similar tools to tighten the meter housing. The plastic housing could be damaged.
OPERATION
Batch and Cumulative Totals
The meter main tains two totals. The batch total may be reset to measure flow
during a single use.
The cumulative total provides continuous measure – ment and may not be
manually reset. The batch total is labeled as TTL1. The cumulative total is
labeled
TTL2.
When the cumulative total reaches a maximum reading of 9999, it will
automatically reset to zero. Press the DISPLAY button briefly to switch
between the batch and cumulative total. Activate the Meter
Turn the meter ON by starting water flow or briefly pressing the DISPLAY
button. The meter will display the batch or cumulative total from last use.
Press DISPLAY briefly to display the batch total. Hold the DIS PLAY button
down for three seconds to reset the batch total to zero. The meter is

Turbine Rotor The meter is virtually maintenance-free.However, it is important
the rotor moves freely. Keep the meter clean and free of contaminants.
If the rotor does not turn freely,apply a penetrating lubricant on the
rotor,shaft, and bearings. Remove any debris or deposits from the rotor using
a soft brush or small probe. Be careful not to damage the turbine rotor or
supports.
_ CAUTION : Blowing compressed air through the _turbine assembly could
damage the rotor.
Battery Replacement
The meter is powered by two AAA alkaline batteries which may be replaced while the meter is installed. When batteries are removed or lose power, the batch and cumula tive total sreset to zero but the factory calibration is re tained. If the meter display becomes dim or blank,replace the batteries as follows:
- Remove the four Phillips-head screws from the face of the meter and lift the face plate from the turbine.
- Remove the old batteries and clean any corrosion from the terminals.
- Install new batteries. Make sure the positive post is in the correct position.
- When the batteries are replaced,the face plate will power ON. Check the display to ensure normal functions have resumed before assembling again.
- Reseat batteries, if necessary, and position the face plate on the turbine housing. To avoid moisture damage,makes retheO-ring is fully seated.
Tighten the four screws on the face plate.
