(DBF110) Illustration 1 DBF110 Alternative Location Secondary Lint Trap Installation Guidelines Please note: DBF 110 fans are not explosion proof. Do not use the fans if apotentially explosive situation may exist. DONOT USE with heated air in excess 140°F (60°C). Fan and Switch Mounting The recommended location of the booster fan is a minimum of 15 linear (not equivalent) feet of duct from the dryer outlet. If the fan is mounted closer than the recommended 15 feet, it may develop enough pressure to lift wet lint into the fan impeller resulting in excessive lint loading in the fan. The best location for the fan to be mounted is as close as possible to the termination of the duct work. (Exception: If a secondary lint filter is installed between the dryer and the booster fan, the booster fan may be mounted within the minimum distance otherwise recommended (See illustration to left). An NB mounting bracket attached to a rafter or joist should be used to stabilize the fan. Although not recommended, a vertical rigid duct may support the fan if the duct is securely stabilized. (Consult local codes prior to supporting the fan in the duct alone.) Duct work should be attached to the inlet and outlet of the fan by means of FC vibration isolation clamps (not included)or duct tape. The duct connection should be properly sealed to prevent leakage and loss of fan performance. Flex duct connections between the dryer duct connection and exhaust duct should be stretched as smooth as possible. Calculating Duct Run To calculate the length of your planned duct run, measure from the dryer to external venting point in roof or wall. For each bend or elbow add 5-7 feet to your total duct run calculations. The DBF4XL can be used on runs up to 108 feet. Pressure Sensor Switch Operation Fantech’s DBF110 is equipped with Fantech's Patented DB10 pressure switch. The DB10 is a positive pressure sensing switch which recognizes dryer operation and activates the booster fan from an independent electrical circuit. This eliminates connections through the dryer circuit which may void the manufacturers’ warranty as well as manual systems which require the attention of the operator or costly current/ temperature sensing systems. The electricity to the booster fan is connected in series through a normally open terminal on the switch. A pressure tap is connected to a fitting on the side of the switch. When the dryer begins operation, positive pressure in the duct causes the switch diaphragm to expand, closing the circuit to the booster fan. An integral delay-on-break timer in the switch will cycle the fan on for intervals of 10 minutes. This will continue until the dryer has stopped and the timer delay period has lapsed. Drying cycles, the booster fan, the delay timer and the pressure switch are not adversely affected by the starting/stopping intervals. Fan Installation Step 1. Selecting Fan Location Fan must be mounted a minimum of 15 feet from the dryer outlet. If the fan is mounted closer than the recommended 15 feet, it may develop enough pressure to lift wet lint into the fan impeller resulting in excessive lint loading in the fan. (Exception: If a secondary lint filter is installed between the dryer and the booster fan, the booster fan may be mounted within the minimum distance otherwise recommended (See illustration to left).The best location for the fan to be mounted, in any application, is as close as possible to the termination of the duct work. In order to perform recommended maintenance, fan location should allow sufficient access for service. Refer to dimensional drawings shown above. Step 2. Mount Bracket Using the wood screws provided, attach the mounting bracket to a support beam at the selected location. Bracket is provided with grommets in order to isolate any vibration and prevent the transmission of sound through the structure. Be careful not to overtighten. Fan mounting can be in any angle (see ill. 2), however, vertical mounting is recommended to reduce condensation buildup in the fan. If a horizontal installation is necessary and condensation buildup may pose a problem, a .|4" hole drilled in the bottom of the housing (along with an NPT insert [by others] and drain tubing) will allow condensation to drain. Step 3. Mount Fan For proper operation, the switch diaphragm must be positioned vertically. (Illustrations below show diaphragm position for horizontal, vertical and ducts installed at an angle.) Wiring box should be positioned for easy access. Attach fan to the mounting bracket with the self tapping screws provided. Care should be taken not to strip the plastic housing. Although screw pilot holes are not required, .|32" (or smaller) pilot holes are recommended. NOTE: Steps 2 & 3 may be reversed. Electrical Connection DO NOT CONNECT POWER SUPPLY UNTIL FAN IS COMPLETELY INSTALLED. MAKE SURE ELECTRICAL SERVICE TO THE FAN IS LOCKED IN "OFF" POSITION. 1. This unit...
