Grease Boss G25 Model 216

Manufactured prior to 2020

The Grease Boss G25 216 was manufactured from late 2016 through to early 2020. It was produced with two electrical versions: V2.1a and V2.1b. The operation of each electrical version is identical, however the versions have slightly different servicing characteristics.

The G25 216 had the option of a pump-out unit installed (as shown). When installed the pump-out function was manually operated, but protected by an interlock to prevent the pump-out function from emptying the unit while the automatic heating cycle was active.

General Maintenance

Daily & Weekly

Remove and clean the filter basket.

 

Empty or dispose of the FOG container.

 

Check the wiper blade.

 

Element Fault

The “Element??” fault is determined by measuring the temperature rise over a set period. The fault indicates that the system has tried to heat the tank but it did not heat within the pre-set 1 hour 30 minutes allowed.

Cause of fault

The probable cause is an element failure or, less likely, that the element relay has failed. It is also possible that the G25 did not reach temperature because of an unusual inflow of cold water. It’s worthwhile resetting the fault and allowing another cycle to complete, to test that the fault is not an anomaly.

Fault state

The “Element??” fault state is latched until it is reset. The fault state will need to be reset after replacing the element, relay, or to test another cycle.

Reset Version 2.1b

This fault can be reset by depressing the “Fault” and “Heater” buttons on the front panel together and holding for 10 seconds.

Reset Version 2.1a

Remove the electrical controls cover and press the ESC button on the Crouzet Controller for 2 seconds.

Normal System State

The Fault light should be flashing once every 2 seconds.

Pump Out

The pump out option on the Grease Boss 216 can be used to occasionally empty and flush out the unit, it may also reduce the frequency of external pump outs. You may want to do this to eliminate odour or sludge build up, however the usual daily maintenance on the grease trap is still required.

The pump only works in the early morning

The pump out programme will not activate until the oil extraction cycles has been completed. As this usually takes place between 2am and 4am the prime time for pump out is 5 hours after this cycle is complete. This means the pump will only work until 9am.  The pump out should be carried out early in the morning.

Operating the Pump

Open the control panel door and press the blue button marked “PUMP”.

Refill with water immediately

After emptying the unit you must refill with water immediately. If the tank is not refilled with water the heater element will burn out. You can refill the unit by running water into the sink that empties into the grease trap.

Resetting the unit

If you have lifted the lid for any other reason, then you must ensure that the sensor tab is positioned over the sensor unit.

If the red light is not flashing then the unit must be reset. Press the red “POWER ON” button once. After a few seconds the red light should start flashing once every 2 seconds. If the red light stays on constantly then there is a fault with your unit and you should contact your service agent.

Trouble Shooting

Red light is on (continuously without Flashing)

Check the magnetic switch and wiper are in position. If the lid has been removed for any reason, press the red button to reset the machine. The light will change from continuous to flashing mode

Not extracting oil

Is the power on? Check to be sure the power is on and the time control is set correctly. Check mains connection. If power is being supplied and there is still no display check fuses or contact your supplier.

Are removable parts cleaned? Remove the lid and clean away any build-up that may be present on the wiper blades, collection chute or outlet tray. Assure that the wiper blades are properly located in place with the wiper blades contacting   the roller. Replace wiper blades when worn.

Check the heating and extraction cycles are working. Make sure the cycles have been correctly set as per instructions. The default time is 2am-4am (NZ time). The tank should heat for 15 minutes prior to default start time. If the tank does not heat then the heater element may need inspecting.  After the heating cycle the extraction cycle should begin. You should be able to hear the noise of the roller turning. If the motor cannot be heard or the roller is not turning then your system needs to be serviced.

Excessive Water in the Collection Container

Cycle Settings. Check the timer cycle settings are not set for too long a period. The unit should not run excessively after the grease and oils have been extracted (2 hours maximum operation).

Check water flow. Make sure that the water flow to the unit does not exceed the rated flow and that there are no drain line blockages downstream from the unit.

Low level of oil waste. If only a relatively small amount of oil is present in the wastewater, the amount of water that is collected in the oil bin can be more than that of the oil. Adjust the cycle timing so as to reduce the cycle duration.

Water Overflows from the Unit

Has the strainer basket been maintained? If water overflows from the inlet chamber the basket may need emptying. Remove, clean and re-install.

Does the inlet gasket need replacing? General overflowing can also result from a worn inlet gasket or a blocked outlet pipe. Replace gasket and clean all possible blockages downstream of the unit.

Has sediment been allowed to build up over time? Over time, sludge builds up at the bottom of the unit and blocks the path of the flow underneath the outlet baffle. Clean as per maintenance instructions. Build up of sludge may severely reduce efficiency of unit and lead to overflow.

Odour Reported

Has maintenance been carried out? Ensure all recommended maintenance is carried out.

Check the back flow prevention from sewer line and vent the outlet.

Check for scum adhesion especially sour milk froth around the liquid surface level, skim off occasionally or use sink shower to rinse inside with warm water.

Flush occasionally with clear hot water.

Steam Coming from the Unit

Check the water level, steam is usually a result of low water level. Do not run the unit with low water levels as you risk damaging the heater element.

Siphoning can cause a reduced water level in the unit.  This usually occurs when the downstream piping of the unit is not properly installed or has been modified.  Turn off the unit immediately and consult your service agent.
