CAUTION: These water meters are

not recommended for installation

downstream of the boiler feedwater

pump where installation fault may

expose the meter to boiler pressure

TROUBLESHOOTING and REPAIR

CAUTION! Never attempt to remove a

ow sensor when there is pressure in

the pipe. Loosen the compression nut

slowly to release any trapped pressure.

If uid sprays out when removing the

sensor, stop turning and depressurize the pipe. Fail-

ure to do so could result in the sensor being thrown

from the pipe, resulting in damage or serious injury.

WARRANTY/RETURN

Rotor Replacement.Rotorsareeasilyeld-replaced.Shaft

and rotor are a single unit, and are not replaced separately.

If replacement is due only to normal shaft wear, bearing re-

placement is probably not necessary. If the rotor has been

damaged by impact, the bearings should also be replaced.

Rotor and bearings can be ordered as a kit (see parts listing).

Followthesesteps:

1.Unscrewthethreadedbearinghousingstoexposethe

shaft ends. If bearings are being replaced, back them

completely out.

2.Removetherotor.Putthenewrotorinitsplace.

3. Thread in one bearing housing part way, then the

other. Take care to start the end of the shaft into

the bearing hole before tightening further.

4.Screwinbearinghousingsuntiltheybottom.

Note: Do not use excessive force.

5.Checkforfreespin.Blowinglightlyontherotor

should result in it spinning rapidly and coasting

to a smooth stop.
