Weekly Maintenance
Check Feed Water Pressure (35 to 100 psi; 241.5 to 689 kPa) – The feed
water pressure of some water systems tends to fluctuate. If water pressure goes
below 35 psi (241.5 kPa) or above 100 psi (689 kPa), it could damage the MIOX
OSG.
Check for Leaks – Ensure that hoses and fittings are tight and leak-free. Correct
any leaks with Teflon tape. Do not use any type of Teflon paste since excess could
potentially break free and gum up the brine proportion pump or water softener. If
the cell perimeter is seeping, tighten all perimeter bolts (Table 13). Check the brine
proportion pump fittings regularly for seepage and check the connections to verify
that there is no salt around the flange sealing area.
Check for Loose Connections/Corrosion – Check cell leads and lugs for
corrosion. For light corrosion, clean cell leads and lugs with a fine sandpaper or a
wire brush. If severe corrosion is present, replace the cell lead. Torque cell lead
connections to 40 ft-lbs (54 N·m).
Check Chlorine (FAC) Production – Check and note chlorine production on the
MIOX OSG Log Sheet (Appendix D) to identify trends over time.

Check Water Softener (< 1 grain) – Test water flow from the water softener with
a hardness test kit to ensure that the softener is functioning properly. Water should
be less than 1 grain (17.1 mg/l as CaCO
3
) hardness.
