Discharge Configurations

Installation

Step 1 – Remove Access Door(s)

• Determine the proper discharge configuration based on application and how the fan was ordered from the factory (see to the right)
• Use an Impact driver and a 1/2 inch socket to remove the 5/16 inch fasteners and access door(s) on the left and/or right side of the unit if airflow is desired in that direction
• The number of access doors and fasteners will change depending on the unit size
• Save all fasteners from the access door to install ductwork or Square Duct Adapter flanges
• Left and Right discharges will have a blank off panel installed on the inline discharge of the unit
• Do not power up the fan without removing at least one discharge panel

Step 2 – Remove Housing Fasteners

• Remove (4) additional 5/16 inch fasteners per side on the left and/or right sides of the unit to allow installation of ductwork or square duct adapter flanges (see below)
• Save all fasteners to install ductwork or Square Duct Adapter flanges

Step 3 – Mount Square Duct Adapters (Optional)
If purchased, square duct adapter flanges are provided for the specific discharge configuration that was ordered

• Square duct adapter will come in (2) or (4) piece designs depending on unit size (see below)
• Mount square duct adapters to inlet and outlet(s) depending on discharge configuration using the appropriate number of flange pieces and 5/16 semi-gimlet fasteners removed in Steps 1 and 2
• Reinstall fasteners that were removed in Step 2 in the corners of the left and right discharge flanges, not doing so will void the warranty and could lead to structural issues with the fan

Step 4 – Mount Unit to Structure

• Fans can be mounted in horizontal or vertical applications
• Isolation is recommended but not required. Please use isolation if ordered
• Place the unit in the desired location and mount to the structure

Step 5 – Install Ductwork to Fan

• Using holes on inlet and outlet(s) or using Square Duct Adapter flanges, mount ductwork to fan in all desired locations
  • For Left and Right discharges reuse the 5/16 inch semi-gimlet fasteners removed in Steps 1 and 2.
  • Reinstall fasteners that were removed in Step 2 in the corners of the left and right discharge flanges, not doing so will void the warranty and could lead to structural issues with the fan
  • Hardware for the inlet and Inline discharge is supplied by others
• Install fan with approximately three wheel diameters of straight duct before and after the fan (see below)
• Flexible duct connectors are recommended for mounting to the inlet and outlets of the fan (see below)
• Do not power up the fan without removing at least one discharge panel
