Hydrotech 6700 XTR Valve Upflow Automatic Water Softeners Operation Manual - Manual (Page 7)

Operating Instructions
Water Pressure
Your conditioner is designed to operate under normal water pressures from 20 psi to 100 psi.
Regeneration and Automatic Bypass
Water conditioners are factory set to regenerate at 2:00 a.m. during a period of little or no water use. The regeneration
cycle lasts approximately two hours, after which soft water service is restored. While regeneration is taking place, hard
water automatically bypasses the water conditioner if required. Use of water, particularly hot water, should be avoided at
this time to prevent hard water from filling the water heater.
New Sounds
You will notice new sounds as your conditioner operates, such as the hum of the timer or click of the actuator arm. During
regeneration, it will be common to hear the sounds of water running to the drain.
Manual Bypass (Figure 4)
In case of an emergency such as an overflowing brine tank, you can isolate
your water softener from the water supply using the bypass valve located at
the back of the control.
In normal operation the bypass is open with the ON/OFF knobs in line with
the INLET and OUTLET pipes. To isolate the softener, simply rotate the
knobs clockwise (as indicated by the word BYPASS and arrow) until they
lock.
You can use your water related fixtures and appliances as the water supply
is bypassing the softener. However, the water you use will be hard.
To resume soft water service, open the bypass valve by rotating the knobs
counter-clockwise.
