Night Mode Operation
NOTICE
Night mode enables machine operation when person-
nel are not present. If the machine encounters a prob-
lem during Night mode, such as a hose rupture or
electrical problem, property damage may result.
Night Mode is used to maintain chemical temperature
and to circulate the chemicals in low-pressure circula-
tion during periods when the machine is not is use, such
as at night or over a weekend. At specified intervals
Night Mode cycles the pumps on and off. If installed, the
temperature control may also be cycled on and off. Dur-
ing Night Mode, the agitators may be turned on or off
when desired but will not cycle on or off with the
"on-time" and "off-time" periods. To run agitators, simply
turn them on as usual either before or after beginning
Night Mode.
When Night Mode is turned on, the period of time known
as "off-time" begins. The machine stays at rest for the
specified amount of time, which will be displayed on the
screen and counted down until the time has elapsed.
When the specified duration for off-time has elapsed,
the period known as "on-time" begins. During on-time,
the Iso and Poly Pumps are on. The Temperature Con-
trol will also be activated. Just as in off-time, the amount
of time remaining will be displayed on the screen. When
on-time has elapsed, the pumps are turned off and
off-time begins. This sequence of going from off-time to
on-time and back will continue until Night Mode is turned
off.
To see how the night mode information is displayed, see
Status Screen, page 19.
