Important Information in UsingtheSystem:
A period of time after the system shutoff, the product
water TDS value will be higher in less time, this is a
normal condition, just to discharge a small amount of
product water;
(System Alarm is a natural concomitant of this condition ,
if the alarm disappeared after producing the water a
minute later , system do not need any treatment;)
Before prolonged periods of non-use (such as during a
vacation) it is recommended that the cold water supply
valve be turned off. If it is more than one week, please
flush the filter thoroughly for at least 5 minutes before
reusing it;
If leaks occur and persist on system, please first turn off
the water supply valve. Call Kohler -Free Technical
Support line directly or your local distributor authorized by
Kohler;
Local water conditions and actual volume of water can
affect filter life. Be sure to replace the cartridge when
prompted by the performance LED indicator.
