General Information This manual describes the installation of the Round In Round out (VRRF) VAV units with mounting and recommended wiring of the VRRF units. • For controls setup and operation parameters, reference the following literature: Upon receiving the equipment, please inspect each unit and components for external or internal damage. Refer to the bill of lading to insure all equipment and accessories have been received.
Installation Due to their weight and size, VRRF units should be suspended from the uppermost ceiling, independent of the false ceiling grid. Suspension devices are to be supplied by the installer. Units must be installed level in the vertical or horizontal position.To check if the unit is a vertical or horizontal unit, look at the model number of the unit as compared to the Service Model Number Description in this installation guide.

Heat Retrofit not possible(b) Pneumatic Normally Closed Parallel Fan Elec. Heat Retrofit not possible(b) Pneumatic Normally Closed All Others 1 Pneumatic Normally Open Single Duct Elec. Heat 2 Pneumatic Normally Open Parallel Fan Elec.
Installation When installing the VRRF to a pre- existing unit, remove power from pre-existing unit and lock and tag out unit. Remove or pull back insulation and remove the amount of inlet ductwork necessary to install the RIRO damper. (See Figure 2, p. 7 for VRRF lengths.) 6. Remove air valve from existing VAV unit by breaking the seal around air inlet and the VAV unit. Once it is loose, remove air valve. (See Figure 5) Figure 5.
Installation removing the old tubing from the airflow switch and using the black tubing provided in the adaptor kit. Connect the airflow switch to the high pressure port of the VRRF unit.There is a tee located in the VRRF unit control box for this. Installation Option Original Ductwork 1. Make sure the existing VAV unit has its air valve set to the open position allowing airflow.With a DDC unit this can be done with Summit (BMTW-SVN01*-EN), Rover™ (EMTX-SVX01*-EN).
Installation New Facility VRRF Installation (Non-Retrofit) Table 3. Note: When installing VRRF, make sure the controller is level so the transducer can read airflow accurately. Important: Make sure inlet and outlet ductwork are adequately supported before installing VRRF. 1. Before hanging VRRF, ensure that the VRRF will have a minimum of 1.5 duct diameters of strait duct prior to the inlet of the VRRF.

Installation air temperature. In order for the auxiliary sensor to function as a supply air temperature sensor on VAV units with reheat and to properly determine the control action (heat, cool) it must be located upstream of the VAV unit. The auxiliary temperature is then compared to the zone temperature. If the supply air temperature is 10 degrees above the zone temperature, then the control action will be heat.
Installation Table 8. DIP switch settings (continued) Table 8.
Installation All binary outputs from control board are 24 VAC. Connection points for unit UCM controller are shown in Control Diagrams: • All wiring must comply with the National Electrical Code™ (NEC) and local codes. • Ensure that 24 Vac power supplies are consistent in regards to grounding. Avoid sharing 24 Vac between controllers. • Avoid over tightening cable ties and other forms of cable wraps.This can damage the wires inside the cable.
