CHECK WATER PRESSURE AND PUMPING RATE:

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:
1)  MINIMUM water pressure required at the softener tank inlet is 20 psi. IF PRESSURE IS OVER 100 PSI, A PRESSURE REDUC-

ING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE WATER SOFTENER.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• 

Do not

 install if water pressure exceeds 100 psi (689 kPa). If the system water pressure exceeds 100 psi, the installation 

must

 use a pressure limiting valve. Contact a licensed plumbing professional if you are uncertain how to check your water 

pressure.

  Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum 

prevention.

IMPORTANT NOTE

If the source is a municipal or a community water supply and daytime water pressure is 85 psi or more, nighttime pressure may 
exceed 100 psi. Call the local water department or plant operator to obtain pressure readings. If the source is a private well, the 
gauge on the pressure tank will indicate the high and low system pressure. Record water pressure data below:

WATER PRESSURE

 Low _______ psi    High _______ psi

2)  If the source of water is a private well, the pumping rate of the well pump must be suffi cient for satisfactory operation and BACK-

WASHING of the WATER SOFTENER. (See SPECIFICATIONS AND OPERATING DATA, Section 5).

LOCATE WATER CONDITIONING EQUIPMENT CORRECTLY:

Select the location of the water softener with care. Various conditions which contribute to proper location are as follows: 
1)  Locate as close as possible to water supply source.
2)  Locate as close as possible to a fl oor or other adequate drain.
3)  Locate in correct relationship to other water conditioning equipment (Figure 1).
4)  Temperatures above 150° F (66° C) will damage the softener and void the factory warranty. 
5)  Do NOT install the softener in a location where freezing temperatures occur. Freezing may cause permanent damage and will also 

void the factory warranty.

6)  Allow suffi cient space around the unit for easy servicing.
7)  Provide a non-switched 110V, 60Hz power source for the control. (Reference transformer to verify proper power supply voltage.)
