Programming

1. Set days of regeneration on skipper wheel (Figure 11).

• Pull all skipper pins outward (away from control).
• Rotate skipper wheel until day arrow points to current day or number 1.
• Depress skipper pin(s) at day(s) for which regeneration is desired.

2. Set the time of day.

• Grasp timer knob and pull outward.
• Rotate in either direction until the timer arrow points to the actual time of

day.

• Release timer knob.

Note:

With the time of day properly set, the conditioner will regenerate at about

2:30 a.m. If you prefer to have the unit regenerate at an earlier or later time, simply
set current time-of-day accordingly (e.g., to have the unit regenerate at 4:30 a.m.—
two hours later—set the clock two hours earlier than the actual time of day.)

Note:

The Timer Locking Pin should always be horizontal (Figure 11) during

operation.
