Settings - Culligan MARK 89 Installation And Operating Instructions Manual

Settings

The Mark 89 and 812 Water Conditioners are designed to perform efficiently on a wide range of water supplies.
Before the unit can be recharged and put into service, several settings must be made.
BACKWASH
Backwash, the first step in the recharge cycle, expands and loosens the resin bed, and flushes away accumulated
turbidity. The backwash interval is preset at the factory for 10 minutes, which is adequate for most water supplies.
It is adjustable, however, from 5 to 30 minutes. It is recommended that backwash last long enough so that the
effluent from the drain line is clear. Backwash too long and water is wasted, not long enough and the tank becomes
fouled with sediment.
If backwash time adjustment is needed, refer to Fig. 8.
• Grasp the front cover by the slots and carefully pull forward to
remove cover. Lay the cover aside in a safe place.
• Loosen screw (A) about 1½ turns. DO NOT loosen screw (B).
• Holding the cam gear (located beneath the backwash dial),
rotate the backwash dial (C) until the desired backwash time
lines up with indicator mark (D).
• Tighten screw (A).
NOTICE: Adjusting the backwash time may cause the salt dosage
setting to change. If the salt dosage needs to be
reset, do not tighten screw (A), and refer to the Salt Dosage
section.
TIME OF RECHARGE
Although the need to recharge is determined by the Soft-Minder
control, time of day the conditioner will actually
recharge can be set on the timer mechanism.
The timer is factory set to recharge about 2:00 a.m., a time when
water usage is at a minimum for most families. If water is drawn
during recharge, hard water will automatically be bypassed to service. If it would be more convenient to have the
water conditioner recharge at a different time of day, the setting may be changed as follows,
referring to Fig. 8.
• Remove the timer cover.
• The position of the peg (H) in relation to the time-of-day dial (J) determines the time when the unit will begin to
recharge.
• Loosen the screw and lift the white time-of-day dial and rotate it until the desired time of recharge is opposite
the peg (H). Please note that whenever the time of recharge is changed, the time-of-day setting may be changed
also.
NOTICE: Whenever the time of recharge is changed the time of day must be reset also.
TIME OF DAY
Upon completing the installation, the timer must be set to the correct time of day. Time of day must also be reset
after any kind of power interruption, such as that caused by an electrical storm. See Fig. 8.
• Determine the correct time of day.
• Grasp the gear (K) and lift straight up (the white time-of-day dial will lift with it). Rotate the gear until the
correct time of day lines up with the pointer (P). The dial is spring-loaded and will return its position when
released. Make sure the teeth mesh.
