Please leave it with the owner when the job is complete. Illi RECEIVING AND HANDLING Upon receiving dampers, check for both obvious Illi and hidden damage. If damage is found, record all �, necessary information on the bill of lading and file t. a claim with the final carrier. Check to be sure that Ih / all parts of the shipment, including accessories, Ill', `I_t. are accounted for. Dampers must be kept dry and clean. Indoor I storage and protection from dirt, dust and the . / weather is highly recommended. Do not store at temperatures in excess of 100°F(37°C). 4, . -' -,,, 1 c, ��� �, SAFETY WARNING: �� Improper installation, adjustment, alteration, `�I service or maintenance can cause property damage, injury or death. Read the installation, operating, and maintenance instructions ,� thoroughly before installing or servicing this equipment. Due to continuing research, Greenheck reserves the right to change specifications without notice. Pre-Installation Guidelines The basic intent of a proper installation is to secure the damper into the opening in such a manner as to prevent distortion and disruption of damper operation.The following items will aid in completing the damper installation in a timely and effective manner. 1) Check the schedules for proper damper locations within the building.Visually inspect the ii A spreeeerear damper for damage. All ll MAI.IMIA PttacM1meMS 2) Lift or handle damper using sleeve or frame. Do not lift damper using blades or linkage. 1111mallmminns When handling multiple sections assemblies, use sufficient support to evenly lift at each �l==_ section mullion(see Figure 1). Do not drag,step on,apply excessive bending,twisting, or M1=== racking. -=_- =�. MWti section Campers 3) Do not install screws in damper frame that will interfere with damper blades and prevent Figure 1-supports for lifting a them from opening and/or closing. multi-section damper 4) Damper must be installed into duct or opening square and free of twist or other misalignment. Damper must not be squeezed or stretched into duct or opening.Out of square, racked,twisted or misaligned installations can cause excessive leakage and/or prevent free operation. 5) Damper must be kept clean,dry and protected from dirt,dust and other foreign materials prior to and after installation. Examples of such foreign materials include but are not limited to: a) Drywall/mortar dust b) Firesafing materials c) Wall texture d) Paint overspray Pre-Installation Guidelines continued.... 6) Damper should be sufficiently covered as to prevent overspray if wall texturing or spray painting will be performed within 5 feet(1.50m)of the damper. 7) ACCESS:Suitable access must be provided for damper inspection and servicing.Where it is not possible to achieve sufficient size access, it will be necessary to install a removable section of duct. Counterweight Adjustment Procedure for BR Models Dampers are shipped from the factory with frame flange location and flow direction as ordered.Location and size of both counterbalances(blade edge,adjustable blade weights)are dependent upon flow direction and damper size.The damper must be mounted square and plumb and must operate freely before any weight adjustments are performed.Contact Greenheck for required modifications to change flow directions. The following instructions should be followed when attempting to adjust counterweights on the BR series damper. Figure 1,1A,& 1B shows the typical location of the adjustable counterweight assembly.Depending on the size of the damper and specified start open pressure,the damper may have more than one counterweight assembly.

When adjusting the counterbalance weights,you will need to adjust the full open pressure and start open pressure.Both steps will need to be done. Adjusting Full Open Pressure and Closing Force Figure 2 Adjustable counterweight assembly Adjusting the closing force will also affect the full open pressure. Figure 3 shows the blade in the full open position.Additional weights can be added to increase the closing force.Removal or trimming of weights will reduce the closing force.After adjustment,verify blades close under no airflow from the full open position.Increase the closing force if the blades fail to close. • Counterbalance Adjustment for BR-1X Series: Horizontal mount - Vertical Up Airflow cont Damper Blade Adjusting Start Open Pressure y / Counterweight Adjustment When the blades are in the closed position,the adjustable weights are used for the start open pressure Bracket Counterbalanced I of the damper.Sliding the weights toward the blade seal will increase the start open pressure and sliding Weights\ the weights toward the blade edge counterweight will decrease pressure(Figure 4). / y mil If sliding the weights to the furthest left position(toward the blade seal)does not provide a high enough start open pressure,additional weights can be added.In this case,the closing force will also increase. �JI Blade Edge Counterweight m m , Figure 3-Adjustable Increases Start Decreases Start counterweight assembly Open Pressure Open Pressure detail Figure 4:Counterweight adjustment for start open pressure.Blade is shown in full close position Dampers are factory adjusted to the start open pressure,based upon your order, for the specified flow direction.Typically,a minimum of one weight plate will be used to keep blades closed,although only the mounting bracket may be sufficient for small damper sizes.

Final Adjustment Check After adjusting the counterweights,verify that no interference occurs between the counterweights and the adjacent blades.If any interference,adjust counterweights.Also verify that the damper blades close under no airflow from the full open,1/2 open,and 1/4 open positions.If blades do not close,adjust weights as required.
