Line 21:

If the power is out for an extended period (hours) and the utility estimate for repair is long, the pH and ORP probes should be removed and placed into water to prevent damage due to drying out.

=== Restarting ===

=== Restarting the Main Pump ===

Observation has suggested that even a relatively brief outage (more than 30 minutes) may result in cloudy water being pumped to the pool upon startup. Therefore, it is recommended that a brief backwash is performed first after an outage above this threshold (until the outflow is clear). Otherwise, it may take several hours for the pool to clear.

Once the pump is operating (after completing the backwash):

* Bleed air from all four sand filter tanks.

* Bleed air from the boiler.

* Reset the low water cut-off on the boiler (as needed).

* If the boiler was operating when power was lost, a thermal trip fault may have occurred. Clear the fault by pressing the red button on the front of the boiler.

Note that the ORP probe tends to read low when out of water for a period of time. Expect the ORP reading to have dropped, resulting in extended chlorinator operation. Minor overshoot of ORP (and chlorine PPM) may result.
