Valve Packages General Data FIELD MOUNTED PACKAGES Rittling hydronic fan coil units have standard valve packages available as a factory built assembly and fieldinstalled option for the main cooling coil and optional heating coil. All valve packages are manufactured within strict tolerances and are hydrostatically tested for leaks. Valve packages are shipped loose for field assembly to ensure a leak free system as factory mounted valve packages often become damaged during shipment. All cooling piping and components are located directly above the auxiliary drain pan to allow condensate to be captured and properly drained. Insulation of the factory valve package is not required. However, all field connections downstream of the valve package should be insulated to prevent condensation from missing the auxiliary drain pan. Valve Package Components Rittling valve packages consist of a variety of components and selection of each combination is dependent upon the application. The following sections provide a detailed description of each of the components. Following this section are additional schematic illustrations and mechanical specifications and photos. Piping System/Placement Valve packages are available for two or fourpipe systems with left and/or right hand connections. The heating and cooling connections can be located on the same or opposite sides of the unit in fourpipe systems. All coil connections are left hand as standard unless specified differently. Interconnecting Piping Interconnecting piping refers to the copper piping which is attached to the coil connections and to which all other components (i.e. control valves, end valves, circuit setters, etc.) are attached. Piping is ½" nominal (5/8" OD) copper. Deluxe or Basic Valve Packages The basic valve package includes only the main components of the valve package (i.e. interconnecting piping, control valves, and end valves). The deluxe valve packages also include unions at the coil connections and a strainer on the supply water pipe along with the basic components. All valve package components are solder end connections. Unions The unions are cast bronze construction and close with a minimum amount of effort. Used for quick connect and disconnect of valve package components to minimize required field labor during servicing of the unit. Strainer The Ytype strainer body is constructed of brass with a 6 mesh 304 stainless steel screen. Used for removal of small particles from the water supply pipe during normal system operation. The strainer helps protect the coil and minimizes the chance of control valves clogging. Screens should be regularly removed and cleaned as part of a routine maintenance schedule. Balance Valves The balance valve body is constructed of bronze and is used to balance hydronic circuits. END VALVES Each basic and deluxe valve package includes a ball valve for the supply water pipe and one of the following end valves on the return water pipe; ball valve, manual circuit setter, or automatic circuit setter. These valves serve as the field connection points on all of the Rittling valve packages. Consult the factory for inclusion of the other types of valves as end valves. Ball Valves Ball valves, also known as end valves, allow the unit to be cut off for servicing purposes. They have a low resistance to water flow, operate easily, and are often used for water balancing. These valves have a compact handle that rotates 90 degrees to a fully open position. The valve body is forged brass and the ball is polished brass with virgin Teflon seats and seals. Ball valves are available as end valves on both the supply and return water pipes. Manual Circuit Setter A manual circuit setter, also known as a manual flow control valve, acts as both a flow setting device and a stop valve, taking the place of a ball valve. This valve allows water flow through the fan coil unit and can be set quickly and accurately. The manual circuit setter includes two measuring ports in the valve body to be used for pressure drop measurements during system balancing. This pressure drop can be compared to factory supplied curves showing the corresponding flow rate. This valve shall have a 360 degree turn handwheel with memory feature including a locking feature for tamperproof setting. Automatic Circuit Setter An automatic circuit setter is an automatic flow control device that includes a ball valve cast in the valve body and is located on the return water pipe. The automatic circuit setter consists of a stainless steel/brass flow cartridge and a contoured orifice plate. As the pressure drop increases, the flow cartridge will move into the contoured orifice plate to decrease the flow. This flexing action provides a constant flow, independent of pressure (280 psi), and makes it difficult to clog and resistant to cavitation damage. This valve sets flow through the coil without any action required by a system balancer. The automatic circuit setter includes two measuring ports in the valve body to be used for pressure drop and temperature measurements. 30

Valve Packages General Data CONTROL VALVES Valve packages are available with or without control valves. All control valve packages are shipped loose for field mounting and wiring. 2Way On/Off Valves These ½" valves are normally closed to the coil as standard and will isolate the coil during a loss of power. Normally open valves are also available upon request. Upon response to a signal from the controller, the valve will be either fully open or fully closed. These valves are located in the water supply pipe, have a c v of 3.5, and close off ΔP of 20 psi. A means of relieving pump head pressure must be accounted for when twoway valves are selected, most notably when used in combination with automatic changeover. 3Way On/Off Valves These ½" valves are normally closed to the coil as standard and will isolate the coil during a loss of power. Normally open configurations are simply achieved by turning the valve around. Upon response to a signal from the controller, the valve will be either fully open allowing full flow to the coil or fully closed to the coil diverting full flow to the bypass line. All 3way valve configurations include a balance fitting in the bypass line to allow proper flow balancing. These valves are located in the water supply pipe, have a c v of 4.0, and close off ΔP of 20 psi. 2Way Modulating Valves These ½", 24V valves modulate the flow of water (000%) through the coil in response to a signal from the controller and are normally closed to the coil as standard. Normally open valves are also available upon request. All modulating valves are threewire floating equal percentage valves, designed for precise temperature control. All valves feature a magnetic clutch to extend the life of the motor and gear train, manual operating lever/position indicator facilitates field setup, and easy to use lever terminal blocks. These valves are located in the water supply pipe, have a c v of 4.0, and close off ΔP of 50 psi. A means of relieving pump head pressure must be accounted for when twoway valves are selected, most notably when used in combination with automatic changeover. 3Way Modulating Valves These ½", 24V valves modulate the flow of water (000%) through the coil in response to a signal from the controller and are normally closed to the coil as standard. Normally open configurations are simply achieved by turning the valve around. 3Way valves allow the water supply from the water supply pipe to mix with bypass water from the bypass line. This mixture exits through the supply water pipe to the coil. All modulating valves are threewire floating equal percentage valves, designed for precise temperature control. All valves feature a magnetic clutch to extend the life of the motor and gear train, manual operating lever/position indicator facilitates field setup, and easy to use lever terminal blocks. These valves are located in the water supply pipe, have a c v of 4.0, and close off ΔP of 50 psi. Please contact the factory regarding any special valve requirements.

WIRING DIAGRAMS Wiring diagrams should be provided at the time the order is released instructing Rittling how to wire the DDC controller and all accessories to meet the required control operation. Rittling Fan Coil with Electric Heat The electric heating elements are located in the fan coil units in the preheat position. They are located in such a way as to prevent stratification and air bypass for optimum heating efficiency. The electric heating elements are situated between the fan discharge and the cooling coil. This prevents access by room occupants. Cabinets: The fan coil unit is fully insulated to ensure safe, low surface temperatures. Motors: Energy efficient 20V/60Hz/Ph permanent split capacitor motors are standard. A 3 speed motor switch is also provided as a standard. Sub Panel and Electrical Blockoff Plate: All fuses, fuse holder, contactors, and terminal blocks are premounted and prewired to the sub panel. The electrical blockoff plate prevents access to the fan coil end pocket which houses all contactors, field wiring terminals, transformers, relays, etc. Magnetic Contactors: The magnetic contactors are furnished to break all ungrounded conductors. The contactor(s) are located in the end pocket premounted and wired to the sub panel. Grounding: Ring type grounding terminals are provided for each power source. Field Wiring Terminals: Field wiring terminals provide a means to easily connect with a single power source. These are suitable for copper wire and are sized in accordance with National Electrical Code. Control Systems: There are four two pipe cooling with electric heat control systems available. One must be chosen with electric heating unit. Each of these is described in detail on pages 4245.. Total electric heat Manual cool/heat changeover 2.

Electric Heating Element Construction Information 2 4 6 3 5 MOUNTING PLATFORM The electric heating elements are mounted to a galvanneal steel plate. This plate is attached to the fan deck by several screws. This allows the motor/fan assembly and electric heat to be removed at the same time for servicing. 2 HEATING ELEMENTS The electric heating element has been designed to handle total electric heating and intermediate seasonal heating requirements. Electric heating elements are designed for 60 hertz/ phase 20, 208, 240 and 277 supply voltages. All electric heating elements are constructed of nickel chromium resistance wire and have a maximum operating temperature of 850 deg F. 3 COIL TERMINALS Coil terminals are constructed of nickel plated steel with ceramic terminal insulators and bracket bushings. 4 LINEAR LIMIT SWITCH The linear limit switch is used as the primary safety protection. It is an automatic reset thermally operated safety device. The switch operates using a long capillary tube which extends the length of the electric heating element. If the capillary senses an excessive temperature (factory preset) at any point, the electric element is deenergized. The break temperature is nonadjustable. The switch automatically reenergizes the electric heating element after the temperature falls to an acceptable range. The electric heating element will be deenergized if the capillary tube is damaged or ruptured. 5 FUSIBLE LINK The fusible link is used as a secondary safety protection device. These cutoffs are manually replaceable with a non conductive thermal pellet holding spring loaded contacts closed. When a preset temperature is exceeded the pellet will melt, allowing the contacts to open and break the circuit.

Determine the required heating element KW using 208V incoming voltage. Step : Determine the room sensible heat loss, in BTUH. In this example, the sensible heat loss is 6,000 BTUH. Step 2: Determine the air temperature rise for the unit size selected. Generally, the unit is selected based on cooling requirements. The CFM for each unit size is listed in Table A on page 8. Use the formula below to determine the air temperature rise. T = BTUH T = 6000 T = 6.8 F required CFM x.085 330 x.085 Step 3: Determine KW and number of heating elements based on air temperature rise required from Electric Heating Capacities Table. Answer: Based on 6.8 F temperature rise required, use a 2.2KW heater element with 208V incoming voltage. 46
