IMPORTANT PLEASE READ:
• Warranty of this product extends to manufacturing defects.
• The information, specications 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 product should be installed by a plumbing professional on potable water systems only.
• This product must be installed in compliance with all local and state and municipal plumbing and electrical codes. Permits may be required at
the time of installation.
• If operating pressure exceeds 100 psi a pressure reducing valve must be installed. If operating pressure drops below 30 psi a booster
pump must be installed.
• Do not install the unit where temperatures may drop below 32°F or rise above 100°F.
• A prelter should be used on installations in which free solids are present.
• A constant voltage of 120V/60Hz (unless otherwise specied) must be supplied to the controller to maintain proper function.
• Union or ange ttings are recommended at the control valve’s inlet, outlet, and drain connections
• If distance of drain line is over a 10 ft. vertical or 25 ft. horizontal run, increase drain line one pipe size over that provided on the control valve.
• Do not make a direct connection to the drain. Provide an air gap of at least four times the diameter of the pipe to conform to sanitation codes
and to permit observation of the ow.
