Installation precautions
WARNING:
Installation and maintenance must be performed by a qualified professional.
CAUTION:
• Make sure that all connecting pipe work is water tight.
Safety rules
• Service should not be performed on any valve in an active hydronic loop.
• Before attempting to make any required adjustments, properly isolate and drain the
branch loops or system that require service and allow the valves to reach a safe
handling temperature and zero pressure condition.
• Use proper safety equipment including gloves, goggles, or similar tools to avoid
contact with system fluids and common hazards.
• Use proper tools and lifting equipment when installing or servicing the valve. Be sure
it is properly supported at all times.
• Failure to follow these instructions could result in personal injury, death, and property
damage.
Installation guidelines
• The valve is uni-directional and can be installed in most attitudes. The preferred
installation is to mount the valve in the return piping.
• Installation of strainers and isolation valves is recommended.
• Valves can be used with up to 50% ethylene or propylene glycol mixtures.
• Be sure to install the valve with the arrow pointing in the direction of flow.
• Do not position the actuator below the horizontal axis of the pipe. See
Install the
actuator (page 9)
• When installed in vertical pipes, be sure to position the valve with the actuator cable
connections facing downward.
• There must be a minimum of 8 in (200 mm) access space above the actuator.
• There must be a minimum of 4 in (100 mm) access space surrounding the actuator.
• Follow all instructions provided with the valve actuator for proper wiring and
connections.
NOTICE:
The hydronic system must be properly vented to remove all entrained air. Liquid media
containing debris or other particulates should be filtered to avoid damage to or
obstruction of the pressure independent control valve, which could cause the valve to
malfunction.
Pipe hanging installations
Be aware of water weight in the valve and connected piping when installing your system.
