The displayed value will be a letter from A to Z.7 To exit this mode, turn the main power key switch to the off position.Selection of Low Voltage Cutout Threshold:FACTORY DEFAULT: S (STANDARD)The AquaRide is equipped with a low voltage cutout feature to prevent over-discharging the batteries. This feature will automatically shut down thescrub system when the battery voltage falls to the selected threshold. The cutout level is adjustable. The standard setting is 31 volts (1.72 volts percell) and the alternate setting is 32.5 volts (1.81 volts per cell). Select the proper cutout level based on the battery manufacturer’s specifications. Itis important to note that some maintenance free batteries (including some gelled electrolyte cells) are capable of being safely discharged down to1.72 volts per cell. To select between the two cutout levels:1 Turn the main power key switch to the off position.2 Press and hold the scrub system off switch.3 While holding the scrub system off switch turn the main power key switch to the on position.4 Continue to hold the scrub system off switch until the scrub off indicator turns green.5 Release the scrub off switch.6 The status display will now show “S” or “A”.

The maintenance mode settingsare 1 to 5 and the restore mode settings are 6 to 9. For each mode (maintenance or restore) the values represent a relative load on the motorswith the small numbers (1 & 6) being the least load and the larger numbers (4 & 9) being the greatest load. A setting of 1 for the maintenance modeand 6 for the restore mode will provide an equal load for the motors. The same is true for settings 2 & 7, 3 & 8, and 4 & 9. NOTE: 4 & 5 providethe same load for the maintenance mode.Fixed Pressure Mode1 Turn the main power key switch to the off position.2 Press and hold the maintenance mode switch.3 While holding the maintenance mode switch turn the main power key switch to the on position.4 Continue to hold the maintenance mode switch until the maintenance mode indicator is green.5 Release the maintenance mode switch.6 Press the scrub system off switch to proceed to the pressure adjustment operation.7 The status display will now show a number from 1 to 5. This represents the maintenance mode scrub pressure. Use the maintenance modeswitch to set the desired pressure.8 Press the scrub system off switch to save this setting.9 The status display will now show a number from (1 + the setting from step 7) to 9. This represents the restore mode scrub pressure. The restoremode indicator will now be illuminated. Use the restore mode switch to set the desired pressure.10 Press the scrub system off switch to save this setting.11 The status display will now show “d” to indicate that the procedure is done.12 The new setting will be saved and will remain in effect until it is changed again.
