NOTE: The commanded cooldown temperature must always be at least 15 degrees Fah-
renheit (8 degrees Celsius) hotter than the hottest ambient temperature or the hottest cold
water temperature that will be encountered. If this rule is not followed, achieving the de-
sired cooler temperature may take a long time, or even be impossible.
During operation, the cooldown bath step starts immediately when the previous (high-tempera-
ture) bath ends.
1. The cooldown valve opens when the cooldown step begins. The cooldown valve does not
close until the end of the cooldown step.
2. When high water level is achieved, the drain opens until the water level falls below high level,
then the drain closes.
3. The drain continues to open and close as needed to maintain high water level.
4. The step timer starts 15 seconds after the desired cooldown temperature is achieved. The tim-
er runs for one minute.
5. When the one-minute step time expires, the cooldown valve closes and the drain opens. The
drain remains closed only if the machine was programmed to not drain, as to prolong the cool-
down or allow the injection of chemicals into the cooler bath.
