Erie Motorized Zone Check ValveModel:VT2212G13B020: 1/2" fittingsThe Erie motor operated valves have long been considered the industry standard in fan coil control. Erie's familiar brands are used in residential hydronic temperature control applications.PRODUCT APPLICATION:PopTop Series valve bodies and actuators provide easy installation for a variety of heating and cooling applications. Valves actuator can be installed after valve body has been installed onto fan coil, baseboard, plumbing or air handler. VS Series valves are available for low pressure steam applications.
__________________________________________________________MountingThe valve can be mounted in horizontal or vertical piping. When installed in horizontal piping, the actuator must be above the valve body. When installed in horizontal piping the actuator can be tilted left or right but it must not be tilted below 85° from vertical.__________________________________________________________Erie Motorized Check Valve1/2" sweat connections, spring loaded normally closed, 110volts.[Other configurations can be ordered; see chart below]__________________________________________________________HELP » Contact Customer Support Toll-Free help line offering product info and ordering support Online e-mail technical and installation support__________________________________________________________PRODUCT INSTALLATION:Inspection: Inspect the package for damage. If package is damaged, notify the appropriate carrier immediately. If undamaged, open the package and inspect the device for obvious damage.Return damaged products.Requirements: Tools [not provided] Wrench 1 to 1-5/8" [if threaded valve] Soldering equipment [if sweat fit] or flare Other accessories as appropriatePrecautions: Electrical shock hazard! Disconnect power before installation to prevent electrical shock or equipment damage. Make all connections in accordance with the electrical wiring diagram and in accordance with national and local electrical codes. Use copper conductors only. All conductors shall be provided with insulation rated for the highest voltage motor and end switch circuits. Avoid locations where excessive moisture, corrosive fumes, explosive vapors, or vibration are present. Avoid electrical noise interference. Do not install near large conductors, electrical machinery, or welding equipment. When making lead connections within the actuator, use caution not to put leads or connectors below the motor.Note » make certain there is no overhead water source that may drip onto valve actuator. In normal service, some condensation may occur on or around the valve. A drip pan may be necessary or the valve body may be insulated.PipingThese valves must be piped so the paddle closes against the direction of flow. Flow is from B to A. When installing the actuator to a normally closed valve, the actuator must be placed in the manually open position by using the manual operating lever. The first time the valve is operated electrically, the manual operating lever of the actuator will transfer to the automatic position. The manual operating lever can be used to allow flushing of the system after installation. The valves are designed for application in closed hydronic heating and cooling systems. High levels of dissolved oxygen and chlorine found in open systems may attack the valve materials and result in premature failure. Install over a drip pan if condensation in chilled water applications occurs.Note » Three-way valves always require a normally closed actuator. Three-way valves are always closed at the B port when no power is applied to the motor. On power-up the valve closes to A port on three-way valves. Orient the three-way valve body as needed for normally open or normally closed flow through coil.Sweat Connections:Do not solder with actuator in place, or with paddle against seat, as the heat can damage the unit. Before soldering, move the manual open lever into Open position then remove the actuator from the body. Orient paddle so it is not against a seat.Use lead or tin based solder with melting point below 600 °F. Do not overheat. Direct flame tip away from valve. Cool valve quickly with a wet cloth.Body assembly can be submerged for leak testing prior to attaching the actuator.CHECK OUT: Make sure the valve stem rotates freely before and after installing the actuator. If the stem does not operate freely it may indicate that the stem was damaged and may require that the valve be repaired or replaced. After the piping is under pressure, check the valve body and the connections for leaks. After the valve and actuator are installed, power the actuator and check the operation.THEORY OF OPERATION:PopTop Series are two position spring return valves. When powered, the actuator moves to the desired position, tensing the spring return system. When power is removed the actuator returns to the normal position.PopTop Series two position spring return valves can be purchased with an optional built-in auxiliary SPDT end switch for interfacing or signaling; for example, zone pump burner control.PRODUCT MAINTENANCE:PopTop Series two position spring return valves are maintenance free. Replace defective modules. Actuator may be replaced without removing the valve.Regular maintenance of the total system is recommended to assure sustained, optimum performance.FIELD REPAIR:Replace any damaged or failed components with complete replacement unit.For more detailed instructions click on the link below:LINK » General Instructions [PDF Format]_______________________________________________________A typical solar domestic water heating system components and layout is shown below._______________________________________________________Product Manufacturer: Schneider Electric (Previously Invensys Building Systems, Inc.)
