MODEL 8636 / 8636-LN / 8636-BAC SUREFLOW™ ROOM PRESSURE CONTROLLER INSTALLATION INSTRUCTIONS WARNING: The Model 8636 Room Pressure Controller must be wired to 24 VAC only. Wiring the unit to 110 VAC will cause serious damage to the unit and void the warranty. The pressure sensor must be mounted through the wall between the controlled space (laboratory) and referenced space (hallway). These installation instructions guide the installer through the installation of the TSI Model 8636 SUREFLOW™ Room Pressure Controller. The installation instructions cover all controller versions: electric actuator/damper, and variable frequency drives (Motor). Unless specified otherwise, figures and instructions apply to all three versions. Please read these instructions thoroughly before beginning installation. This product is classified by Underwriters Laboratories, Inc.® for use in through-penetration firestop systems. See UL fire resistance directory.

Pressure Sensor Installation Figure 2: Pressure Sensor Orientation and Mounting Template WARNING: 800326 pressure sensor must be mounted through the wall between the controlled space (laboratory) and referenced space (hallway), exactly as shown in Figure 2 and 3. 1. Determine pressure sensor location (Figures 1, 2 and 3). Pressure sensor typically mounts in the reference space, and the dummy housing mounts in the laboratory. NOTE: Pressure sensor is not symmetrical. If sensor is to be centered over hallway door, measure one inch to the left of center for 2¼-inch hole. Dummy sensor will be 2” off center on other side of wall. 4. Drill a 7/8 inch hole on the side of the wall that the pressure sensor will be mounted. This hole is for the six-conductor sensor cable. Refer to Figure 2 for a hole mounting pattern. 5. Slide sensor cover to right and remove screw that holds the sensor base to the pressure sensor (Figure 2). Remove pressure sensor and store in a safe place. 6. From the side of the wall the sensor will be mounted, slide the sensor tube through the wall. Mark the tube where it is flush with wall. Remove sensor tube and cut tube 1/8inch shorter than flush marking. NOTE: If 12” sensor tube is not long enough add a 1” to 2” adapter and extend with 2" OD tube. The base of the dummy housing will need to be drilled out to accommodate 2” tube. Do not extend sensor tube with 1” tubing. 2. The pressure sensor must be orientated on the wall as shown in Figure 2. Looking at the mounted sensor, sensor hole is on the left (2¼”) and wire hole is on the right. 3. Drill a 2¼-inch hole through each side of the wall to accept the sensor tube. -2- 7. From the side of the wall the sensor will be mounted, slide the sensor tube through the wall. Slide the dummy base over the end of the tube. Screw the pressure sensor base and dummy base to the wall (Figure 3). 10. Install and screw the pressure sensor and dummy cover onto the bases. Slide covers to the left to hide the sensor. Finished installation should look as shown in Figure 4. 8. Wire the pressure sensor per Figure 7. Run sensor cable to the room pressure controller 4” x 4” electrical rough-in box. WARNING: Do not touch the sensor element in the pressure sensor. Do not run wires through the air passage. Doing so will damage the sensing element. 9. Insert fire protection sealant (provided) into 7/8” wire hole to seal. Figure 3: Cutaway View of Mounted Pressure Sensor Figure 4: Pressure Sensor Mounting -3- Transformer Installation WARNING Make sure no power is applied until all wiring is complete. Follow all applicable electrical codes, and have qualified personnel install the transformer. Figure 5: Transformer Installation Note: 115 Volt, single phase, 60 Hertz power source is required to power the 800420 transformer. If TSI Transformer is not installed, a regulated 24 volt, single phase, 60 Hertz power source is required to power the controller. 1. Damper Version—Mount a standard 4" 4" 1½" electrical box at a convenient location within 20 feet of the damper/actuator. 2. Motor Version—Mount a standard 4" 4" 1½" electrical box at a convenient location within 20 feet of pressure controller. 3. Run 115 Volt, single phase, 60-Hertz line voltage (115 VAC) to electrical box. Follow all applicable electrical codes. 4. Connect 115 VAC line voltage HOT wire to BLACK wire on transformer and NEUTRAL wire to WHITE wire on transformer (Figure 5). 5. Connect the RED wire on 800414 transformer cable to either YELLOW wire on the transformer and the BLACK wire to the remaining YELLOW wire. 6. Screw the transformer to the electrical box. 7. Damper Version—Run transformer cable from the transformer electrical box to the damper/actuator box. Have at least 8 inches of cable coming out of the damper/actuator box before trimming cable to length. 8. Motor Version—Run transformer cable from the transformer electrical box to the pressure controller. Have at least 8 inches of cable coming out of the pressure controller rough in electrical box before trimming cable to length. -4- Pressure Controller Installation Pressure Controller Rough-in 1. Select the mounting location of the pressure controller. The construction plans normally show the mounting location. If no location is specified, then the unit is typically installed as shown in Figure 1, either in the laboratory or in the hallway. 2. Install a standard double gang electrical box (4” 4”). 3. Slide the pressure controller cover to the right and remove three screws holding the electronics to the base (Figure 6). Remove base. 4. Install the base to the 4” 4” electrical box. The base’s “THIS SIDE UP” arrow must be pointing towards the ceiling. Note Two screws are hidden behind the cover when full open. The cover will slide to the right approximately 2 inches until a stop is hit. Pull cover to completely remove from electronics and expose the screws. Figure 6: Pressure Controller Mounting Pressure Controller Wiring WARNING: Do not connect more than 24 VAC to any terminal. Do not apply voltage to the RS-485 output or analog output. Severe damage may occur to the unit if voltage is applied. 1. Remove the connectors from the back of the pressure controller. 2. Refer to the wiring diagram for proper wiring installation. 3. If additional options need to be wired, refer to building prints for proper wiring diagram. 4. Plug the connectors back into the pressure controller. 5. Carefully push the wires into the electrical box and mount the pressure controller. Install three screws to hold pressure controller firmly to base. Install cover and slide left to hide display. -5- WARNING: Monitor must be wired exactly as diagram shows. Making modifications to the wiring may severely damage the unit. Figure 7: - Wiring Diagram – Electric Actuator -6- TSI Actuator/Damper Installation WARNING: Building prints normally determine damper location and mounting configuration. They supersede the guidelines below. 1. The actuators are shipped mounted to the damper. No adjustments are needed prior to mounting the assembly. 2. The damper must be installed with the damper shaft parallel to the ground (Figure 8). 3. Slip-fit dampers mount INSIDE the ductwork. Rivet slip-fit damper to duct work to ensure damper rotates correctly. Alternate: use 1-inch or shorter screws. Make sure screws do not interfere with damper blade rotation; damper blade rotates outside of damper sleeve. 4. Bolt flanged dampers securely to ductwork, but do not “force” damper to fit (deforms damper). No ductwork can be inside of dampers, or interfere with damper rotation.
