4. Wash bio-wiper ™ and/or copper faceplate with soapy water. Rinse and dry
thoroughly. Note the condition of the copper on the instrument side of the wiper. It is
normal for copper to corrode and turn green, especially after the instrument has been
removed from the water. This corrosion will slightly reduce the shutter’s anti-fouling
ability the next time it is deployed.
5. Buff each with a pad of green Scotch Brite
®
(or similar) until shiny.
6. Clean the bio-wiper ™ shaft and the shaft hole using an isopropyl alcohol-saturated
cotton swab. Allow to dry.
7. Re-install faceplate.
8. Check the screw used to secure the bio-wiper to the shaft: a hex key must fit
snugly into the screw socket. If the socket is in any way compromised, use a new
screw (4-40 x 3/8 in. 316 stainless steel treated with anti-seize. These are shipped
as part of the meter’s spare parts kit.)
9. Slide the bio-wiper ™ over the shaft. Be careful not to twist it on, thus rotating the
shaft. If the wiper does not slide on easily, insert the screw into the expander hole,
turning slowly until the b
io-wiper ™ slides easily onto the shaft.
10. Rotate the bio-wiper ™ into the closed position.
11. Set the gap between the b io-wiper ™ and the instrument face to 0.03 in. (0.8 mm).
An improperly set gap will either fail to clean the face or cause the motor to draw
excessive current.
To gauge 0.03 in., fold a piece of paper in
half, then in half again, then fold a third time,
creasing the edges. It’s now 8 sheets and
about 0.03 in. thick.
