Consequently, it is important that the fan be carefully inspected for visible and concealed damage before installation. Report any damaged or missing items to the shipper immediately. Follow the installation sequence shown below. Attach the plenum and hood to the roof curb using a suitable fastener in each of the prepunched mounting holes. Care must be taken not to bend or distort the plenum and fan components during installation. Hood Installation Sequence 1. The roof curb is mounted and secured over the roof opening to the roof structurals. Lifting Lugs 2. The plenum (factory assembled) is lowered through the curb and roof opening until its mounting channels rest on the roof curb. Lifting Lugs are provided. (Fig. 1) Roof Curb Mounting Channels Plenum 3. The hood is lowered onto the curb/plenum assembly. (Fig. 1) 4. The hood and plenum are secured to the roof curb. (Fig. 2) Fig. 1 Fig. 2 Electrical Connections Before electrical connections are made, the supply voltage, phase and ampere capacity must be checked for compatibility with the fan motor. In addition, the supply wiring must be properly fused and conform to local and national electrical codes. If fan is to be wired to a control center, which is available through Greenheck, the control center wiring instructions must be followed. Pre-Starting Checks Check all fasteners and set screws for tightness. The propeller should rotate freely and not rub on the fan panel. The unit was aligned and test run at the factory prior to shipment, however movement of various components may occur during shipment. Proper propeller rotation should be determined by momentarily energizing the fan in the exhaust mode. If the rotation in the exhaust mode is for supply the motor wiring between the fan and the controls should be changed. For 3 phase units, simply interchange any two of the three electrical supply leads. Single phase units should not rotate the wrong direction, since the fan has been pre-run at the factory. Guards Guards are required to protect the fan and nearby personnel. If guards are not ordered with the fan, they must be supplied by the installer. When ordered with the fan, the guard is attached to the bottom of the double venturi panel. Damper Plenum Linkage Adjustments Plenum dampers should open to 45o from closed position. Consult factory before adjusting damper linkages. 2 Routine Maintenance WARNING Disconnect and secure to the “OFF” position all electrical power to the fan prior to inspection or servicing. Failure to comply with this safety precaution could result in serious injury or death. Once the fan has been put into operation, periodic maintenance should be performed on the following items: 1. Motors Greasing of motors is intended only when fittings are provided. Many fractional horsepower motors are lubricates for life and require no further lubrication. Motors supplied with grease fittings should be greased in accordance with the motor manufacturer's directions given on the motor nameplate. 2. Removal of Dust and Dirt Model ESRMD fans require periodic cleaning to maintain proper air performance and reliability. Dirt left to accumulate on propeller blades may cause an unbalanced condition resulting in excessive vibration and premature failure of the fan. Dust and dirt should also be cleaned from the exterior surface of the fan motor and damper actuator(s). Dirt accumulation on the motor/actuator(s) can block ventilation holes and prevent proper cooling. 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 Birdscreen or Filters Low Leakage Control Damper Low Leakage Control Damper VCD-1020 (2) Fan Motor Damper Actuator ACCESS DOOR Control Damper Control Damper VCD-2120 Motor Plate Drive Frame Angle (2) Propeller Optional Diffuser Optional Diffuser Double Venturi Panel Model ESRMD & ESRMDF Warranty Butterfly Dampers (2) Greenheck warrants this equipment free from defects in material and workmanship for a period for one year from the purchase date.
