Hardness:
Recommended hardness not to exceed 10 grains per
gallon, or 170ppm . System will operate with hardness over 10 grains
but the membrane life may be shortened . Addition of a water soft-
ener may lengthen the membrane life .
Water Pressure:
The operating water pressure in your home should
be tested over a 24-hour period to attain the maximum pressure .
If the incoming water pressure is above 85psi, a pressure regula-
tor is recommended and if over 100psi, then a pressure regulator is
required .
Copper Tubing:
Reverse Osmosis water should not be run through
copper tubing as the purity of the water will leach copper causing
an objectional taste in water and pin holes may form in the tubing .
Watts supplies speciality filters that can be used if copper tubing
follows the Reverse Osmosis unit . Be sure to follow any state or local
regulations during installation .

Using Quick-Connect Fittings
Cutting
Cut the tube square . It is essential that the outside diameter be free
of score marks and that burrs and sharp edges be removed before
inserting into fitting .
Connecting
Make certain to push the tubing completely into the connector until it
comes into contact with the internal tubing stop . The collet (gripper)
has stainless steel teeth which hold the tube firmly in position while
the O-ring provides a permanent leak proof seal .
Pull on the tube to check that it is secure . It is a good practice to test
the system prior to leaving the site and/or before use .
Disconnecting
To disconnect, ensure the system is depressurized before removing
the tube . Push in collet squarely against the face of the fitting . With
the collet held in this position, the tube can be removed . The fitting
can then be reused .
