excessive evaporation.
Note: After a power interruption, the machine will restart automatically,
including the cleaning pump if pump switch (E) is in the ON position.
14. When using the machine, it is recommended to lock the front wheels in order
to give it more stability.

RECOMMENDED PREVENTIVE MAINTENANCE

Lift sink (G). A retainer bar at the back will maintain it the open position.
Do not open the sink while heavy objects are placed inside as the weight
may exceed the force of the retainer bar.
1. If unit is to be idle during weekends or for several days, it should be topped
up and the machine must remain ON.
2. If the unit is to be idle for more than one week, it is recommended to turn the
unit off. Before doing so, lift sink (G) and skim off or absorb any accumulation
of oil from the surface of the liquid. The unit should not remain turned off for
more than 4 weeks.
3. If a high concentration of non-digestible contaminants remains in suspension
inside the liquid, turn on the cleaning pump and let the fluid circulate for a
couple of hours. The liquid will flow through the filter (H) and the filter bag (M)
which will remove the contaminants.
4. Liquid filter (H) should be inspected periodically. If filter is clogged or very
dirty, (weak or no liquid flow through brush and flexible faucet) replace it. The
same process applies for the filter bag (M). This filtering is essential to keep
your liquid clean. See the section "ACCESSORIES" for a listing of available
filter cartridges and filter bags.
5. Ensure that the float switch floats freely in the liquid.
6. The pH of the cleaning solution should always be between 6 and 9. If the
pH of the solution is outside this range, please contact the BIO-CIRCLE™
technical support line. See page 17 for contact information.
7. Inspect the electrical cord and plug regularly. Replace any damaged parts.

ANNUAL MAINTENANCE

Walter recommends that your MINI 100A be inspected and cleaned annually to
perform at optimal efficiency.
Depending on the application, non-digestible matter can accumulate as sludge at
the bottom of the tank over time, which can negatively affect the bioremediation
activity. To facilitate the removal of the sludge, the tank bottom is tapered towards
the drain valve.
- Turn main power switch (I) to "0" and unplug unit.
- Connect a 1 in. hose to the barbed fitting of drain valve (K). Fully open the
valve, wait a few seconds and then close the valve. Repeat these steps 3
times to remove most of the sludge.
If the sludge cannot be removed with this method, follow the instructions below:
