Irregular wastewater inflow, downtime more
than two days.
Should operational shutdown last longer than two
days, flush the separator with 30 litres of water
from the sink daily.
The rubber plug (item 17 page 4 IOM) is removed
because a P-trap is installed after the separator.
Remove the P-trap and return the rubber plug
to the drain hole. The separator has an internal P-trap,
no external P-trap is required on the outlet pipe
The inlet chamber is not maintained.
Remove the inlet chamber cover and use the spray
head to remove deposits on the walls. Do not remove
the basket from the chamber during cleaning.
Oil leaked to the oil valve (pos.5 page 4 IOM).
Clean grease residue from the oil container.
Decomposing grease residue in the oil container.
Clean grease residue from the oil container.
The oil valve slip is clogged
with solidified grease
The heater does not heat.
Check if the green light on the heater is on. If not,
check the plug, the heater thermostat reset button
and the circuit breaker in the electrical switchboard.
The heating element is coated with sludge,
heating itself but not the fat.
Touch the upper sloping plate of the separation
chamber. If operating correctly, the plate should
be hot to the touch. If the plate is not hot then
the heater is coated with sludge and more thorough
maintenance is required, see page 17
- Quarterly maintenance IOM.
Separated grease does not flow
into the oil container.
Clogged oil valve. Plastic ball stuck to the oil valve seat.
Clean the oil valve with a brush - refer to page 15
- Weekly maintenance IOM. Shorten the oil valve
cleaning interval from weekly to daily.
There is only an emulsion or fat free wastewater flowing
into the separator.
-
Water flows into the oil
container.
Oil valve seat or plastic ball is clogged with debris.
Clean the oil valve with a brush - refer to page 15
- Weekly maintenance IOM.
Waste water flows from the
separator
The inlet chamber basket is full of food waste, stopping
water entering the separator.
Empty the basket and consider shortening
the emptying interval to twice daily.
The drain pipe downstream of the separator is partially
or completely blocked.
Clean the drain pipe. Eliminate the cause of the pipe
blockage.
A small diameter drain pipe is used downstream
of the separator and is not able to handle peak
inlet flow.
Replace the inlet reducer with a smaller one to reduce
the maximum flow rate of the separator.
Clogged inlet flow reducer
Bigger pieces of food debris pass through
the sink into the separator.
Install a plughole strainer. Open the inlet chamber lid
and remove any material from the clogged reducer.
