Setting the Time of Day, the Days of Backwash and
performing manual backwashing with the 942F
controls.
Setting the Time of Day
Rotate the Clock Dial
clockwise
until the pointer
indicates the correct time of day. With the time of day
set, the conditioner will backwash at approximately
2:00 a.m. If it is desired to have the unit backwash at an
earlier or later time, simply offset the current time of day
accordingly. For example, to have the unit backwash at
4:00 a.m., set the Clock Dial 2 hours earlier than the
actual current time of day.
Note:
Do not rotate the Calendar Cap by hand
. The
Clock Dial indexes the Calendar Cap daily. To manually
index the Calendar Cap, rotate the Clock Dial
clockwise
one complete turn for every day to be
indexed. Day pins should be in the outward position
during Clock Dial rotation to prevent an undesired
backwash. Reset day pins when completed.
Setting the Days of Backwash
Setting the days that the conditioner will backwash is
accomplished in two simple steps:
1. Pull all of the day pins outward.
2. Push in the day pin(s) for the day(s) on which a
backwash is desired.
NOTE:
The NEXT DAY pin is noted on the control face.
Pushing this pin will insure a backwash the next day at
approximately 2:00 a.m. since the Calendar Cap
progresses in a clockwise direction, pushing the day
pin immediately following the NEXT DAY pin
counterclockwise will insure a backwash occurs the
following day at approximately 2:00 a.m. This
progression is noted on the control face as “FUTURE
DAYS”.
Manual Backwash
Excessive water usage or other service related issues
may create the need to manually backwash the filter.
This function is performed by rotating the Indicator
Knob
COUNTERCLOCKWISE
to the “START”
position. Once in this position, the filter will begin a
backwash within a few minutes. The normal schedule,
established with the pushed in day pins, will not be
disrupted by a manual backwash.
24 Hour Clock
The Performa Cv Series 942F control utilizes a 24 hour
clock dial. This is typically referred to as “Military Time”.
The hours of the day between 12:00 a.m. (midnight)
and 12:00 p.m. (noon) are designated on the clock dial
by the numbers 1 through 12, with 1 being 1:00 a.m.
The hours of the day between 12:00 p.m. (noon) and
12:00 a.m. (midnight) are designated on the clock dial
by the numbers 13 through 24, with 13 being 1:00 p.m.
Be sure to set the correct time of day accordingly.
