Introduction
Congratulations on the purchase of your DracoDrum Minima Combi
The unit is designed for simplicity of installation and use.
On the following pages we will show you the different components of your combi, how to install it
and how to perform fault finding if something should stop working as it should.

Bypass Plate
If you need to bypass the drum, for instance if you are treating for flukes, there is a bypass plate that
can be removed from inside the drum itself and is secured by 2 self tapping screws. This is accessed
by removal of the waste tray.

Installation
Make sure that the Minima is placed onto a flat surface . The unit is not designed to be moved once
it contains water.
When you receive your Minima the spray bar will be in ‘transit position’. Once unpacked, lift the
spray bar enough to turn the valve clockwise half a turn, until tight and then gently place the spray
bar back down into its holder. The water valve should then look as in the picture below under
‘Connecting the Water’.
Attaining Correct Water Level
When fitted,
Gravity fed mode, running water level should be about 25mm below the lip of the bio chamber.
Pump fed mode, this is automatically governed by the standpipe.
Connecting the Water
Water valve operated spray bar. connect your incoming water supply to the valve. In the UK this
should be via a standard 15mm pipe. For international, an adaptor will be required and the valve
body uses a standard 3/4" BSP female thread.
Float Switch
Gravity fed, adjust the internal (Clean side) float switch so that when fully floating, the sensor is just
below running water level (see Attaining correct water level). Tighten screw to secure.
Pump fed, this is governed by the standpipe.

Control Unit
Using Your DracoDrum Minima
Starting your Drum for the First Time
Turn on controller by twisting and unlocking the stop button. You should see a green light and a red
zero. The drum is now ready to go.
Operation
When running, the drum should show a green light to confirm power is on. Initially you will see a red
zero to the right of the unit. This will change as it displays the minutes between the last 2 washes.
When triggered, the red sensor led will flash. This flashing will only occur whilst the sensor is actually
triggering or whilst you are pressing the green button in. Once triggered this initiates a wash "cycle"
and 2 blue leds will light. One for the wash pump and one for the drive motor.
A wash cycle is approximately 30 seconds. Once the 30 seconds is up, the blue leds will extinguish
and the drum will stop. If the red led continues to flash, the drum will continue to wash until the red
led stops flashing. If this situation lasts for more than 4 minutes, the drum will auto stop, wait for 2
minutes and then continuously monitor the sensor. Once the sensor is no longer active, it will auto
restart. Whilst it is monitoring, the red led will come on solidly (failsafe mode).
You can select up to 2 wash cycles for your wash duration, so you can set the drum to wash for up to
1 minute each time. If you need to manually trigger a wash, for example maintenance, you can press
the green button on the controller to start the drum. If there is an issue with the drum, pushing the
emergency stop will shut off all power within the controller as a safety feature.
Making Adjustments
Your DracoDrum allows you to make 2 adjustments to it, the length of the wash and the height of
the water sensor in gravity mode.
Rotations per wash
You can select between 1 and 2 periods per wash. A period is not a full rotation but rather lasts for
approximately 30 seconds. This is to ensure the same part of the screen is not constantly
underwater and all parts of the drum are used equally.
To adjust the number of periods, simply flick the switch on the control box to either 1 or 2
NB: The system will over ride and continue to wash for more durations if the water level should not
have reached the required minimum height that you have set with the internal water sensor after a
wash.

Adjusting the height of the sensor
For gravity fed units the sensor is on the clean side of the drum. This sensor is triggered when the
micron screen becomes dirty and blocked and the water level starts to drop as not enough water is
able to get through.
With the system running, and the drum has just washed, you will have behind the drum what is
referred to as “running water level”. This can and usually is lower than if the main circulation pump
is turned off. To maximise the area of filter screen under water, the waste tray should be half
submerged at this running water level. The float switch should then be set so that the floating tip of
it is approximately 5mm below that.
Gravity Fed
The unit will continue to wash for as many rotations as necessary until the water level reaches the
required height to re-cover this sensor. E.g. if you have your unit set to only 1 rotation but a single
rotational cycle is not enough to clear the debris attached to the micron screen then it will continue
to rotate and clean until the sensor is re-submerged in water. If however you have the system set to
two rotational cycles even if one rotation clears the screen and allows the water to return to the
normal running height the unit will continue for the specified number of cycle rotations.
Configuring the Biological Chamber.
The Biological chamber can be set for fluid or solid media.
If using solid media, an alternative baffle is available from your dealer to maximise the efficiency of
the chamber.
