Installation, Operation and Maintenance Manual

Installation

Greenheck Model ESRMD & ERD fans are thoroughly inspected and test run at the factory, however

damage may occur during handling and shipping. 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.

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 45ofrom closed position. Consult factory before adjusting damper

linkages.

Installation Sequence

1. The roof curb is mounted and

secured over the roof opening to

the roof structurals.

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)

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)

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.

Routine Maintenance

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 45ofrom closed position. Consult factory before adjusting damper linkages.
