STEP 4: Setting Water Hardness
This value is the hardness value of your water in grains per gallon (GPG). If you have the reading in PPM or mg/L,
simply divide that by 17.1 to get the reading in GPG. You must also add (5 x iron level in PPM) to the hardness value.
HARDNESS VALUE = YOUR WATER HARDNESS + (5 x Iron concentration in PPM)
For example, if your water hardness is 20 GPG and the iron level is 0.3 PPM, the hardness value you enter must be
20 + 5 x (0.3) = 20 + 1.5 = 21.5 GPG
Note: If you do not know your water hardness, please call customer service for details on how to send us a water
sample and receive a free water analysis. In the meantime, you can leave the hardness value at default
setting. You can also visit www.rainfresh.ca for details.
STEP 5: Setting Vacation Mode
This function may be activated during a prolonged absence, such as a vacation for more than 2 weeks. The system
will perform a brief backwash and rinse based on advanced setting. The purpose is to keep the water fresh in the
softener tank and plumbing system.
When you return from vacation, return the holiday mode to "NO".
