Motors and actuators should never be sprayed directly with water, steam or solvents. 3. Filter Maintenance (Model ESRMDF) Aluminum mesh filters should be cleaned on a regular basis for optimum fan efficiency. The frequency of cleaning depends upon the cleanliness of the incoming air. To remove filters in fan sizes 24-30, first remove the hood. This is accomplished by removing the two fasteners on one side of the hood and loosening the other two fasteners in the other side of the hood. Hinge the hood over onto the roof deck; DO NOT prop the hood up, the hood could come down accidentally causing injury. The filters can then be pulled from the slide-out racks. On sizes 36 to 54, access panels are provided in the ends of the hood which allow the filters to be removed without removing the hood. Filters should be washed with a mild detergent in warm water. After the filters are dry, an adhesive spray available at most filter distributors may be applied to increase filter efficiency. 4. Fasteners Fan vibration has a tendency to loosen mechanical fasteners. Periodic inspection should include checking all fasteners for tightness. Particular attention should be paid to fasteners attaching the propeller to the motor shaft and the motor to the motor plate. 5. Damper Plenum Linkage Adjustments Plenum dampers should open to 45o from closed position. Consult factory before adjusting damper linkages. 3 Parts List Optional Diffuser Low Leakage Control Damper Control Damper Optional Diffuser Fan Motor Propeller Model ERD ACCESS DOOR Drive Frame Angle (2) Low Leakage Control Damper Optional Diffuser Control DamperControl Damper Birdscreen or Filters VCD-2120 VCD-1020 (2) Fan Motor Damper Actuator Motor Plate Propeller Double Venturi Panel Model ESRMD & ESRMDF Butterfly Dampers (2) VCD-1020 (2) Damper Actuator Motor Plate Drive Frame Angle (2) Double Venturi Panel 4 Warranty Greenheck warrants this equipment free from defects in material and workmanship for a period for one year from the purchase date.
