          (see Section IV-E).
  B. Faulty Meter
     B-1. Disconnect the red wire from red terminal
          B of the fuse block and connect a 0-50 amp
          DC ammeter between the red wire and red
          terminal B. Record the amperage reading during
          the treatment cycle. Compare with the treatment
          meter reading. Use Figure 8 at the end of this
          section to determine amperage on treatment meter.
          If amperage readings do not correlate (= or - 2 amps)
          the meter is defective. Replace meter.

Zero Meter Reading (Treatment Light Operates)
  A. Fuse B blown
     A-1. Replace fuse B. Be sure to check fuse specifications
          given in parts list on page 38.
     A-2. Check to see that connections on fuse clip are
          clean. Dirt and corrosion cause heat buildup
          which can result in a blown fuse.
     A-3. If replacement fuse blows in the next operating
          cycle, or soon after, the electrodes must be
          inspected for a short between the plates. The
          short can be caused by impingement of a conductive
          foreign body such as a bobby pin lodged between
          the plates. Remove the foreign object.
     A-4. Fuse B can also blow if the salt concentration
          in the flush water is excessive. Replace fuse,
          close valve on salt feed tank, and flush head
          3 or 4 times without activating treatment cycle.
          This will dilute the salt concentration.

Zero Meter Reading (Treatment Light Operates)
   A. Fuse B blown
    A-1.  Check meter reading during treatment cycle if
          meter reading registers in the High range, salt
          concentration is excessive. Adjust salt
          concentration. Close salt feed valve Flush toilet
          for a short period and then run operating cycle.
          Check meter reading. Repeat until meter reading
          is in Normal range. Readjust salt feed valve.
          (see Section IV)

  B. Faulty Electrode Pack
    B-1. Disconnect the red wire from red terminal B of
         the fuse block and connect a 0-50 amp DC ammeter
         between the red wire and red terminal B. If there
         is no amperage and the salt concentration is at
         the proper level, then the electrode pack is
         defective. Replace electrode pack
    B-2. During treatment cycle check for proper voltage
         and amperage across electrode pack terminals
  C. Faulty Meter
    C-l. If there is proper voltage and amperage and
         meter does not register in treatment cycle, it
         is defective. Replace meter.

Zero Meter Reading (Treatment Light Inoperative)
  A. Blown Fuses
    A-1. Check fuses B and C. Replace if blown. See
         Treatment Light inoperative for fuse C and Zero
         Meter Reading.
         (Treatment Light Operates) for fuse B.
B. Defective Timer
    B-1. Check for proper voltage (12, 24, or 32 VDC)
         to timer with a voltmeter, between terminal
         T-2 on the timer and terminal D on the relay.
         If there is no voltage, see System inoperative.
    B-2. If there is proper voltage, check timer operation.
         Check for proper voltage (12, 24, or 32 VDC)
         between terminal L-2 on the timer and terminal D
         on the relay during the flush/pretreat cycle.
         If there is no voltage, the timer is defective.
         Replace timer.
    B-3. Check for proper voltage (12, 24, or 32 VDC)
         between terminal T-3 on the timer and terminal D
         on the relay during the treatment cycle. If there
         is no voltage, timer is defective. Replace timer.

  C. Defective Relay
    C-l. Check for proper voltage (12, 24, or 32 VDC)
         between terminals D and G on the relay during
         a treatment cycle. If there is no voltage, check
         all connections and re-check timer.
    C-2. Check for proper voltage (12, 24, or 32 VDC)
         between terminals D and F on the relay during
         the treatment cycle. If there is no voltage relay
         is defective. Replace relay. If there is proper
         voltage, recheck all electrical connections.

Toilet Does Not Flush
  A. Salt Feed Tank Empty
    A-1. Refill salt feed tank (Section V-E)
    A-2. If small end of spring of the check valve is
         toward metering plug, reverse the spring
         "end for end" and slip the large end of spring
         over the large boss on metering plug,
         to reduce tension.

VII. Preventive Maintenance

To assure continued trouble-free performance of the LECTRA/ SAN System, a number of routine preventive maintenance procedures should be performed periodically. The following table lists the parts to be checked, the recommended frequency of maintenance, and the maintenance procedures to be taken.

Salt Feed Tank, Monthly
   1. Thoroughly rinse and wipe out tank.
   2. Check to make sure the tiny vent hole In
       tank cap is not blocked.
   3. Rinse out control valve with fresh water.
Salt Feed Line, Every two months
   1. Remove tubing from salt feed tank and from toilet,
       and remove metering plug. Check all parts for
       obstructions.
   2. Wash out tubing, siphon check valve, and metering plug
       with fresh water.
Treatment Unit, Every two months
   1. Check to see that cover hold down bolts are
       properly tightened.
   2. Clean cover motors and electrical contacts.
   3. Check to see that terminal contacts are properly
       tightened.
Control Unit, Every two months
   1. Inspect and clean electrical connections.
Hose Fittings, Every two months
   1. Inspect all hose fittings and check for tight hose clamps.
