Do not return goods without the prior authorization of Labconco. Unauthorized returns will not be accepted. If the product was damaged in transit, you must file a claim directly with the freight carrier.
Page 19 Step 2 Labconco recommends supporting the blower with 5/16” diameter mounting hardware. See Appendix B: Dimensions for appropriate mounting hole locations. Step 3 Installing vibration isolators or vibration mounting pads between the blower and curb is acceptable. Vibration dampers can be found at local industrial supply company.
Page 20 Step 3 Secure desired outlet position by reinstalling hardware removed in previous step. Reinstall weather cover and hardware saved from Step 1 using the 5/16” nut driver. Connect to Blower Inlet This section will detail how to install the inlet connection according to the blower material.
Page 21 Guy wires from 3 sides are supported off the roof to prevent wind velocities from deflecting the exhaust duct. Structural support is connected to C-clamp coupler. Note: Duct diameters, duct materials, and heights may vary. Labconco does not offer structural supports or guy wires.
Page 22 4722400 adapts the outlet on these blowers to accept 8-inch diameter PVC ductwork. 12” Coated Steel Blowers include a 13-1/2” by 7” rectangular outlet. Transition Adaptor, Labconco part number 7003400, adapts the outlet of these blowers to accept 12-inch diameter PVC ductwork. Section 9: Accessories for additional information on outlet adaptors for Coated Steel Blowers.
Page 23 through the housing. Silicone sealant should be used to seal any air leaks between the duct and blower outlet connection. 12” Fiberglass Blowers feature a 12-3/4” ID outlet connection. 12-inch diameter ductwork will slip into this connection and should be held by sheet metal screws through the housing.
Page 24 Step 3 Locate the harness marked with the “MAIN POWER” label inside the junction box. For 1 HP installations, see Figure 4-6 for a diagram illustrating how to connect the blower to power. Figure 4-6 3-G/Y For 2 HP installations, single or three phase power must be determined The 2HP VFD Motor Spectrum Blowers operates on either single or three phase power.
Page 25 Step 5 Organize all wires and harnesses within the J-box and reinstall the J-box cover and weather cover previously removed. AC Select Switch (For 100-125 VAC 1 HP ECM Only) The 1 HP ECM Spectrum Blower is factory default rated at 208-250 VAC. If connecting to 100-125 VAC, the AC select switch needs be adjusted.
Page 26 This blower contains an electrical motor, which requires proper electrical connection per National Electrical Code to prevent hazards. The National Electrical Code and local codes may require that a circuit disconnect, overload protection, and short circuit protection be included in the installation. The unit should be connected by a licensed electrician.
Page 27 5: Performance Features Spectrum Blowers are dedicated, adjustable laboratory exhaust blowers that maximize energy efficiency for exposure control device installations. These blowers are adjustable and optimized to succeed in most laboratory ventilation environments associated with fume hood and enclosure exhaust. Built-in Vibration Isolation In addition to using vibration dampers on the curb prior to blower installation, isolators are used to mount the motor within the blower housing.
Page 28 20mA and 0-10 VDC input options are standard. Once properly connected, the speed of the blower is set and controlled through the input chosen. If multiple Spectrum Blowers are installed, the BMS inputs can be used to control each Spectrum Blower from one BMS interface.
Page 29 On Board USB Port Allows easy field update of software and download of performance data log. Requires a flat head screwdriver to remove four screws and panel to access USB. 30 days of performance logging can be retrieved from this USB port to aid in troubleshooting. For instructions on how to update software, see Section 7: Using your Spectrum Blower.
Page 30 6: Spectrum Blower Fan Speed Operating System The Spectrum Blower operating system provides user control and useful information with the display screen and keypad. In this section, connecting the blower to a remote ON/OFF switch, choosing control options, setting the speed of the blower, and certification details will be explained.
Page 31 Step 1 Control wires must be run from Figure 6-3 the remote switch to the roof-top blower. For Labconco fume hoods, the blower ON/OFF switch wires are run to the junction box located on the top of the hood. From the hood, it is...
Page 32 Step 3 Remove and replace the green jumper wire that came factory installed in terminals 1 & 2 with the control wires labeled “CONTROL WIRES to terminals 1 & 2” as shown in Remote Switch Terminal Detail of Figure 6-4. Install the white signal ferrule into terminal 1 and the black comm ferrule into terminal 2.
Page 33 Step 2 Set the remote blower switch (if applicable) to its ON position before manipulating the on-board potentiometer. Step 3 Locate the potentiometer on the control panel as seen in Figure 6-2. With a small jeweler screwdriver, adjust the potentiometer setting and measure airflow. Readjust the potentiometer setting as required to set the desired airflow.
Page 34 If not using a remote ON/OFF switch, do NOT remove the jumper as shown in Figure 6-5. Labconco recommends using 22 gauge of shielded cable for the control wires. Using shielded cable will limit interference along the path the cables are ran.
Page 35 (typically a BMS control system). If not using a remote ON/OFF switch, do NOT remove the jumper as shown in Figure 6-6. Labconco recommends using 22 gauge of shielded cable for the control wires. Using shielded cable will limit interference along the path the cables are ran.
Page 36 Step 3 Using the 4-20mA signal, the speed of the Spectrum Blower can be adjusted. Adjust the speed setting by varying the 4-20mA signal and measure the airflow. Readjust the amperage signal as required to set the airflow. Allow a few seconds for the motor to achieve steady state speed after every adjustment.

Page 38 Data Outputs The Spectrum Blower provides both RS-232 & two-wire RS-485 data outputs as follows. Using the outputs provided, the following data can be monitored and logged: 1. Blower status 2. Motor RPM 3. Internal Temperature (°C) 4. Alarms (if any) 5.
Page 39 Settings Motor Configuration This programmed menu option must match the physical motor installed in the Spectrum Blower. Do not change the motor configuration setting of the Spectrum Blower unless it is confirmed to be programmed differently from the physical configuration. See Figure 7-2 to see the physical configuration of both the 1 HP motor and the 2 HP motor without the weather cover installed.
Page 40 Default values of these settings can be seen in Table 7-1. Follow the steps below to change these settings. Delay Time of Alarms There is a delay between alarm condition(s) and alarm warning(s). The default value for this setting is 30 seconds. The purpose of this delay is to limit nuisance alarms by delaying the alarm warning after the conditions for alarms are met.
Page 41 Data Log Rate Data performance logs are stored in the Spectrum and are downloadable for troubleshooting and monitoring purposes. The default is 10 seconds, which logs data every 10 seconds. At a 10 second log rate, the Spectrum can store approximately 30 days of data at a time.
Page 42 To update the software for the Spectrum Blower, the appropriate .hex file needs to be on a flash drive ready for use. To get this file, go to the Spectrum Blower product page on Labconco.com or use the QR code on the product and follow the instructions for downloading the firmware package.

Page 79 Appendix E: Connecting the Spectrum Blower to a Guardian Digital AFM (Airflow Monitor) The following section details how to connect a Spectrum Blower to a Guardian Digital Airflow Monitor. When complete, the Spectrum will be able to communicate to the user at the hood with the AFM.
Page 80 Figure E-2 Step 1 ROOF-TOP Use a flat head screwdriver to remove 6 SPECTRUM screws securing the access panel on the BLOWER Spectrum Blower (Reference Figure 6-1). Pull away the panel to expose the controls display. Save this panel and hardware.
Page 81 for wiring details. For this procedure, input 1 will be used as an example. Once properly wired, the AFM must be programmed to understand the communication being sent from the Spectrum blower. Using the Guardian Digital AFM, follow Steps 4 through 9.
Page 82 This alarm has two notification options: a flashing red LED and displaying ‘External alarm’ on the screen. Set LED and Display icon to desired setting (either enabled or not). Labconco recommends enabling both. Step 8 Select ‘None’ for output relay. It should be the default option.
