C. Defective Timer
     C-l. Check for proper voltage (12, 24, or 32 VDC)
          to the 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.
     C-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, timer is defective.
          Replace timer.
     C-3. Check terminal a on LED for tightness.

Treatment Light Inoperative
  A. Fuse C blown
     A-1. Replace fuse C. 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, then the macerator (larger)
          motor must be inspected for damage or excess
          loading on the shaft. Replace defective motor
          or clean shaft and impeller.

NOTE: See Specification Section for proper amperages
     A-4. Check terminal c on LED for tightness.
  B. Defective LED Board
     B-1. Check for proper voltage (l2, 24, or 32 VDC)
          between terminals (c) and (d) on the LED Board
          during the treatment cycle. If there is proper
          voltage and the treatment light does not operate,
          then the LED Board is defective.
          Replace LED Board.
     B-2. If the proper voltage does not register between
          terminals (c) and (d) on the LED Board, check
          fuse C. (See A above ) If fuse C is good,
          check timer.
  C. Defective Timer
     C-1. Check for proper voltage (12, 24, or 32 VDC)
          to the 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.
     C-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,
          timer a defective.
          Replace timer.
     C-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-4. Check terminal D for tightness.
  D. Defective Relay
     D-1. 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 recheck timer.
     D-2. Check for proper voltage (l2, 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.

LOW Meter Reading
  A. Insufficient Salt
     A-1. Check salt feed tank supply Refill if needed (Section V-E)
     A-2. Check for restrictions in salt feed line.
     A-3. Open valve on salt feed tank.
     A-4. Inspect siphon check valve (Item 5, Fig 11)
          for proper orientation. Be sure it is free of dirt
          or foreign materials. Clean in fresh water.
     A-5. Inspect T-Check Valve (Item 7. Fig 11) or metering
          plug (item 8, Fig. 11) if Raritan Crown Head
          being used. Check for restrictions. Clean in fresh water.

  B. Low Voltage
     B-1. Check voltage with voltmeter between electrode
          studs on Treatment Unit during treatment cycle.
          Low voltage is less than 11.5 VDC (23 VDC for
          Model 24 VDC and 31 VDC for Model 32 VDC). If
          voltage is low, go to B-2. below. If there is
          proper voltage go on to C and D, below.
     B-2. Check voltage to the Control Unit between
          lugs D and E on the relay (see Fig 6) during
          the treatment cycle. Low voltage is less than
          12 VDC (24 VDC for Model 24 VDC and 32 VDC for
          Model 32 VDC). If the proper voltage does not
          register, check main power wiring for proper
          size. Check connections if there is proper
          voltage, recheck wiring and connections between
          Control Unit and Treatment Unit.
     B-3. Check for fully charged battery.

  C. Fouled Electrodes
     C-l. Inspect and clean electrodes (see Section VII).

  D. Faulty Meter
     D-l. 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
          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.

  E. Electrode defective
     E-l. During treatment cycle, check amperage across
          electrode terminals (1/4" studs in center of
          treatment tank)
     E-2. During treatment cycle, check voltage across
          electrode terminals.
     E-3. Check battery voltage at battery during treatment
          cycle. There should be no more than 1 volt difference
          between the battery voltage and treatment tank
          terminal voltage. If voltage drop is greater,
          undersized wiring or a poor connection is indicated.

NOTE: Check Specification Section for proper electrode amperage.

  F. Motor(s) Inoperative
     F-l. Check operation of mixer (smaller) motor during
          flush/pretreat cycle. Check operation of
          macerator (larger) motor during treatment
          cycle. Replace defective motor(s).

High Meter Reading
  A. Excess Salt
     A-1. Close off salt feed valve slightly
