SBX-300, 500, 600
2-SPEED MOTOR CONTROL & IONIZATION FIELD TEST

Pre Set Switches and Jumpers

1. Turn off power to the Smart Box.
2. On the front panel set the Automatic/Manual switch to Auto position
3. On the front panel turn the Ion Output Adjust knob to the off or "0" position. (N/A on 300)
4. On the front panel if an Intermatic time clock (large black body) is used, push all detentes down and rotate the time clock one full turn.
5. On the front panel if a Borg or Grasslin (gray body) push all the detentes away (out) from the center and rotate the time clock one full turn.
6. On the circuit board (Front) mounted to back of front pane; set Hi to Low timeout (red 10 position switch, S-1) to position 1 (test position)

Manual Switch Test

1. Apply power to unit.
   The POWER MONITOR indicator on front panel will be lit.
   The pump will be off.
   The FLOW indicator on the front panel must be off.
   The ION OUTPUT light on the front panel will be out.
2. Turn the AUTOMATIC/MANUAL switch on the front panel switch to MANUAL.
3. Units produced and not updated before January 1989.
   Pump will not turn on.
   Turn the time clock to an "on" position.
   Pump will turn on, after three (3) minutes the pump will still be in high speed.
   When the pump is on, the FLOW light on the front panel will be lit.
4. Units produced or updated since January 1989.
   Pump will turn on. The Manual position overrides the time clock.
   After two (2) minutes the pump will still be on and in high speed.
   When the pump is on, the FLOW light on the front panel will be illuminated.
5. Turn the AUTOMATIC/MANUAL Switch to the AUTOMATIC position.
   The pump will turn off.
   The FLOW light on the front panel will be off.

Automatic Operation Test

1. Place some of the time clock detentes to the "on" position (detentes up or toward the center of the time clock). Rotate the time clock to an "on" position. Rotate the ION OUTPUT control to about 30% (N/A on the 300).
   The pump will turn on and run in high speed.
   The pressure switch will close and the FLOW light on the front panel will illuminate.
   The ION OUTPUT light will be on. (N/A for the 300)
   The POWER MONITOR light will change color about every 3 1/2 minutes.
2. After about 1 1/2 minutes the pump should switch to low speed and stay in low speed.
   The pressure switch will remained closed and the FLOW light on the front panel will stay illuminated.
   The LOW SPEED light on the front panel will light.
   The pump will stay in low speed operation. (If it returns back to high speed there is most likely a problem with the pressure switch, cable or clear plastic tube between the unit and plumbing line or the water flow through the pump and filter.)
   The ION OUTPUT light will be on. (N/A for the 300)
   The POWER MONITOR light will change conditions about every 3 1/2 minutes.
   
   Note: If the flow switch remains closed, the unit will stay in low speed until the filter cycle is complete (time clock rotates to an off position). If for any reason the flow switch opens, the pump will return to high speed. Once flow is established the unit will attempt to return to low speed operation.
   
   
3. Rotate the time clock to an "off" position.
   The pump will turn off.
   The FLOW light will turn off (the pressure switch will be open).
   The ION OUTPUT light will be off.
   The LOW SPEED light on the front panel will turn off.
   The POWER MONITOR light will be on.

FREEZE CIRCUIT TEST

1. Set time clock to an off position.
2. Set Auto/Manual switch to the Auto position.
3. The freeze switch will usually be installed in the plumbing and connected to the Smart Box via the black and white wires (with bullet connectors) in the cord connecting the electrodes and freeze switch. On later models the freeze switch is mounted on the outside and underneath the Smart Box.
   When the temperature is close to freezing the freeze switch will close.
4. On a unit with the freeze switch in the plumbing: Remove the bullet connectors from the freeze switch and connect them together.
5. On a unit with the freeze switch mounted under the enclosure: Disconnect the wires at TB4 pins 4 and 5 and insert a wire jumper in pins 4 and 5.
6. The pump will turn on and run in high speed.
   (When TB-4 pins 4 and 5 on the back board are shorted the unit thinks the freeze switch is closed.)
7. On a unit with the freeze switch in the plumbing: Disconnect the bullet connectors from each other.
8. On a unit with the freeze switch mounted under the enclosure: Disconnect the jumper wire between TB4 pins 4 and 5.
9. The pump will turn off.
10. Reconnect the freeze switch wires.

IONIZATION FIELD TEST (N/A for the 300)

1. Turn the pump on with the MANUAL switch.
2. Rotate the ION OUTPUT knob to 0%.
3. Disconnect the wires from the electrodes and short them together for no longer than 15 seconds.
4. Rotate the ION OUTPUT knob to 30%.
   The ION OUTPUT light should illuminate.
5. Remove the short between the electrode wires.
   The CHECK ELECTRODES or ELECTRODE MONITOR light should illuminate.
6. Turn the pump off with the MANUAL switch.
7. Rotate the ION OUTPUT knob to 0%.
8. Reconnect the wires to the electrodes.
9. FOR A COMPLETE IONIZATION CIRCUIT OUTPUT TEST PLEASE REFER TO OUR IONIZATION OUTPUT TEST.

Set Switches for Normal Operation

Turn off Power to the Smart Box.

Automatic/Manual switch to Auto position

Ion Output Adjust - set to the desired output level. (N/A on 300)

Set time clock:
Intermatic Time Clock: Pull detentes up for the desired filter cycle "on" time and rotate the time clock one full turn.
Borg or Grasslin Time Clock: Push the detentes toward (in) the center for the desired filter cycle "on" time and rotate the time clock one full turn.

Synchronize the time clock to normal time.

On the circuit board (front) mounted to back of front panel: Set Hi to Low time out, red 10 position switch S-1, to position 6 (factory setting for 2 1/2 hours high speed to low speed timeout).

This completes the basic operation field test.
