F-1 a®o Page 12 70 HOW TO MAINTAIN THE F-1000 The F-1000 requires very little maintenance, however, some conditions will cause increased wear on the paddle and/or possible damage to the unit Damage caused by corrosive or abrasive fluids is not covered under warranty •Periodically remove the sensor assembly from the pipe fitting and inspect the meter for signs of wear and obstruc- tions Clean the paddle of any foreign objects Paddle and axle wear can be caused by chemical attack and/or abrasive fluids Replace the paddle and axle if worn Various axle materials are available for corrosive fluids •Although the meter is capable of operating at the high end of the flow range, the meter should not be allowed to operate continuously at flow rates in the upper 1/4 or 25%of the calibrated flow range The paddle and axle life is directly related to the rate of flow and the fluid being measured Corrosive and abrasive fluids moving at high flow rates will cause increased wear requiring frequent inspection and maintenance Ceramic,titanium or rucked axles are available for corrosive and abrasive fluids •O-rings should be inspected periodically Immediately replace the o-rings at any sign of weal;swelling, cracking or discoloration •The meter is designed to withstand minor condensation inside the enclosure Prolonged excessive moisture inside the enclosure, due to high humidity conditions,may damage the meter Reduce the humidity or move the meter to a less humid location •Replace the two AAA batteries every 12 months The program memory is "non-volitile"and will not erase when replacing the batteries Processing power will be maintained for about 45 seconds, preventing the lose of totalizing data, while the batteries are being replaced To replace the batteries, open the rear panel of the enclosure by removing the two Phillips screws After replacing the batteries, be sure the foam insert.s in place and the panel gasket seal ism good condition, before closing the rear panel •Test the electronics by removing the sensor assembly from the pipe fitting and spinning the paddle by hand While +he r. .�.bcr"0" --A n ..+i,- A ..«1..., --1- _ _..4 ....a....*"-.�1__ t...,rs....._ -]_ `t- — -1' sY.i�.:.ng, ua...sua.ay... v .�.a1..11 u. u.., u1aN1ay 'vt111uUry 11LW1 awa ULUL LUt. vatt%,Iy 15 sUp1}J1y1iAg pV WC'r LU U10 WOLCl UUL a signal is not being processed by the circuitry In this case,the circuitry must be serviced by an authorized service center 8.0 TROUBLESHOOTING Situation Leaking Cause.
