Anleitung Zusammenfassung
If a louver is not present and one must be installed, it should be mounted in the center of the uppermost portion of the gable. The area of the louver should be greater than outlet area of ventilator. (See Figures 4 and 5.) 2. There are four sets of holes spaced 90. apart in housing, providing a choice of four depth positions. Reversing brackets produces eight positions. Select proper mounting holes to align bracket and mounting structure on louvers. (See Fig. 3.) Figure 3 — Mounting Housing to Brackets 3. Ventilator may be mounted directly against a gable louver as shown in Figure 4. If louver is sufficiently strong, mounting brackets may be nailed or screwed onto it. Figure 4 — Mounting to Gable Louvers 4. If mounting the vent directly to gable louver is undesirable, a pair of furring strips may be suspended vertically at a minimum of 16 3/4” apart. 5. Ventilator may also be mounted on rectangular louvers as shown in Figure 5. 6. For better performance, cover any open louvered area around vent with plywood or other suitable material. This will improve efficiency of air exchange between attic and outside air. It will also prevent thermostat from being directly affected by outside air. 163. 163.4” MIN. 4” MIN. Figure 5 — Mounting to Rectangular Louvers MINIMUM ATTIC INTAKE AIR REQUIRED Sufficient intake area must be provided in the attic to ensure that fan will not be overloaded and that it will deliver its rated CFM. This can be accomplished with some type of attic venting such as gable louvers or undereave vents. The table below shows minimum intake area needed for each fan installed. MINIMUM ATTIC INTAKE OPENING REQUIRED UNRESTRICTED WOOD LOUVER METAL LOUVER 5.1 Sq. Ft. 6.4 Sq. Ft. 5.9 Sq. Ft. Note: If openings are covered with 1/2” hardware cloth or large mesh expanded metal, increase area by 20%. Double area if fly screen is used. WIRING WARNING: TO REDUCE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT USE THIS FAN WITH ANY SOLID STATE SPEED CONTROL DEVICE. Note: This fan is designed to run on 120V, 60 HZ power only. 1. Thermostat box can be screwed or nailed to a rafter by mounting bracket provided. If nailed, remove thermostat from box before nailing to avoid damage. Connection to existing circuit must conform to local electrical code regulations. 2. Wiring of this unit is done inside attic. Remove cover from thermostat/junction box. Bring power cable at least 6 inches into the box. Fasten power cable to box with appropriate connector. 3. For standard installation, connect the two leads in thermostat/ junction box to the two supply leads. Attach ground wire from the supply to the green ground screw in the box.

See Fig. 7 for wiring dehumidistat to ventilator. 120V, 60 Hz SUPPLY WHITE GROUND BLACK DEHUMIDISTAT TO FAN MOTOR THERMOSTAT & JUNCTION BOX ASSEMBLY Figure 7 — Wiring Diagram for Dehumidistat 5. Replace cover to thermostat/junction box. OPERATION Set automatic thermostat to meet your requirements. The thermostat has an adjustable range from 60. to 120. and operates on a 15. differential. For example, factory setting is 100.. At this setting, as soon as temperature reaches 115., thermostat will close and start ventilator. When temperature has been reduced to 100., thermostat will open and ventilator will stop. Dial pointer may be set at temperature that is best for local conditions. NOTE: Remember the 15. differential. If dial point is set on 120., ventilator will start at 135. and operate until temperature has been reduced to 120., a difference of 15.. (See Figure 8.) Figure 8 — Thermostat F A N O F F 90 60.F 120 MAINTENANCE WARNING: MOTORS ARE THERMALLY PROTECTED AND AUTOMATICALLY TEMPERATURE CONTROLLED AND MAY START WITHOUT WARNING. THEREFORE, MAKE CERTAIN THAT POWER SOURCE IS DISCONNECTED BEFORE ANY ATTEMPT TO SERVICE OR DISASSEMBLE ANY COMPONENTS! IF POWER DISCONNECT IS OUT-OF-SIGHT, LOCK IT IN THE OPEN POSITION AND TAG TO PREVENT APPLICATION OF POWER. Lubricate motor every 6 months using SAE 20 non-detergent oil. Insert 2-3 drops of oil in the oiling hole on the back plate of the motor. TROUBLESHOOTING CHART WARNING: ITEMS MARKED WITH AN ASTERISK (*) SHOULD BE PERFORMED ONLY BY EXPERIENCED AND QUALIFIED PERSONNEL. SYMPTOM POSSIBLE CAUSE CORRECTIVE ACTION Excessive noise. 1. Propeller blade contacting housing. 2. Foreign material inside housing. 3. Motor loose. 4. Motor needs oiling. 5. Dirt accumulation on propeller, causing imbalance. 1. Realign or replace. 2.
