Testing, Operation, Troubleshooting | Greenheck Fan 474750 specification

Testing

1.Turn fan switch on, then off to ensure proper fan operation before cooking equipment is started. Once this is verified, testing can proceed.

2.Heat up cooking equipment with fans off. Once the duct temperature reaches the set point of the temperature controller the fans will start within

5 minutes. If the fans take more than 5 minutes to start, decrease the temperature set point by adjusting the set point on the temperature controller (see Calibration).

3.If an adjustment was made in Step 2, repeat now.

4.After verification of fan start-up, shut down cooking equipment. The fan switch should still be in the off position. Once cooking equipment has cooled below the set point plus hysteresis, the fans will shut down.

NOTE

During testing, if fans do not start automatically in the first 10 minutes of cooking equipment activation, manually start fans to avoid accidental fire system dump due to heat build-up.

Operation

1.Turn fans on and off using the fan switch. It is normal for the fans to remain running after the switch is turned off. The exhaust duct temperature controller will open after heat is no longer present under the hood and the temperature is below the set point plus hysteresis, the fans shall shut down.

2.In the event that the cooking equipment is started without turning the fans on manually, the fans will turn on automatically and remain running with the presence of heat under the hood. Once the temperature is below the set point plus hysteresis, the fans shall shut down.

Troubleshooting

Fans do not turn on automatically upon cooking equipment activation.

•Check wiring to control panel or relay box

•Multiple sensors must be wired separately

•Temperature set point too high, decrease set point

•No power to fans, check breakers/starters/relays

Fans do not shut off.

•Switch must be in the off position

•Cooking equipment hot, wait for it to cool

•Temperature set point too low, increase set point

•Ensure wires connected to appropriate control circuit

Fans cycle off to on when turned off.

•Cooking equipment not cooled enough, retry in

5 minutes

Fans do not turn on quick enough.

• Decrease temperature set point

Maintenance

Daily

Clean the temperature sensor with cloth and degreaser. Keep clean for best performance.

Weekly

Dependant on grease production and grease filter type, clean temperature sensor.

Seasonal

May have to change temperature setting on the temperature controller if ambient kitchen temperatures fluctuate between summer and winter seasons.
