It covers both manual valves and valves mounted on air or electric actuators, including valve insertion, securing heater blocks, routing heater and ground wiring, installing heater cartridges, and inserting thermocouples or RTDs. Safety cautions address proper torque to avoid heater cartridge damage and shock risk, and emphasize correct grounding and actuator alignment to prevent flow blockage.","North America, South America, and Australia/Oceania:  \nP.O.

For a manual valve, remove the knob or handle from the standoff assembly (Figure 2) .  \n2. Remove the CR2/clamp ring from the standoff. Since the oven lid is supplied with a CR2 attached, the one supplied with the standoff is not required.  \n3. Slide the standoff assembly through the opening in the oven lid, with the insulation on the lid toward the valve.  \n4. Place the heater block on the valves. Make sure that each valve is fully inserted, with the valve body flat against the surface of the block. Tighten the cap screws to secure the block to the valves. (See Figure 1)  \n5. Secure the standoffs to the lid by tightening the HWSC-SC6-10B screws in the CR2/clamp rings.  \n6. Slide the heater cartridge through the strain-relief bracket in the oven lid and into its hole in the heater block. Gently tighten the heater cartridge cap screws.  \nCAUTION: Over-tightening the heater cartridge cap screw may result in damage to the heater cartridge and can pose a shock hazard. A fraction of a turn beyond the point of contact is adequate.  \n7. Attach the ring lug connector of the ground wire to the heater block at the point provided (see Figure 1) . The heater must be grounded.  \n8. Insert the thermocouple or RTD into the heater block, as required by the application.  \n9. Fit the MHA/manual handle adapter into the standoff, engaging the squared end of the MHA firmly in the squared end of the standoff drive shaft.  \n10. Press the black plastic retainer over the end of the standoff, with the manual handle adapter shaft protruding through the retainer.  \n11. Slide the knob or handle over the MHA with the set screw toward the flat face on the MHA shaft. Tighten the set screw.  \nSee remaining steps in Both Valve Types section beginning on page 4.  \nVICI Technical Note 604-Revised 04/2021 2  \nValve on an Air or Electric Actuator  \nRepeat Steps 1-3 for each valve.  \n1. For a valve on an air or electric actuator, loosen the HWSC-SC8-10B screw in the CR3/clamp ring (Figure 4) and remove the valve/standoff assembly from the actuator.  \nFIGURE 3:  \n2. Remove the CR2/clamp ring from the standoff. Since the oven lid is supplied with a CR2 attached, the one supplied with the standoff is not required.  \n3.
