IMPORTANT PLEASE READ:
The information, specifications and illustrations in this manual are based on the latest information available at the time of
printing. The manufacturer reserves the right to make changes at any time without notice.
This manual is intended as a guide for service of the valve only. System installation requires information from a number of
suppliers not known at the time of manufacture. This product should be installed by a plumbing professional.
This unit is designed to be installed on potable water systems only.
This product must be installed in compliance with all state and municipal plumbing and electrical codes. Permits may be
required at the time of installation.
If daytime operating pressure exceeds 80 psi, nighttime pressures may exceed pressure limits. A pressure reducing valve must
be installed.
Do not install the unit where temperatures may drop below 32°F (0°C) or above 125°F (52°C).
Do not place the unit in direct sunlight. Black units will absorb radiant heat increasing internal temperatures.
Do not strike the valve or any of the components.
Warranty of this product extends to manufacturing defects. Misapplication of this product may result in failure to properly
condition water, or damage to product.
A prefilter should be used on installations in which free solids are present.
In some applications local municipalities treat water with Chloramines. High Chloramine levels may damage valve components.
Correct and constant voltage must be supplied to the control valve to maintain proper function.
