Safety precautions
Please read this manual before attempting to unpack, set up, or operate the equipment
and pay attention to all the warnings, cautions and notes. Failure to do so may result in
injury to the operator or damage to the equipment.
1. This equipment has been designed to operate on either a 115 V 60 Hz or a 230 V
50/60 Hz AC power supply, as specified at the time of ordering. The electrical
requirements for each unit are indicated on the label above the power receptacle on
the rear of the base unit. Do not attempt to use the equipment with any other power
source than is indicated on this label.
2. Most of the modules making up the system have been designed to be drip and splash
resistant, but they are not waterproof. Take care to avoid submerging the components
or subjecting them to unnecessary amounts of water. This is particularly important in
the case of the base unit, where water could enter the ventilation holes. If water does
enter the base unit or recycle injection module, immediately disconnect the equipment
from the power supply. Leave the equipment to drain and dry out completely, then
have it checked by a qualified electrician before using again.
3. The jar support platform (illuminated diffuser) is sealed to the base unit and can accept
spillage from the jars. From time to time, check that the diffuser is not cracked or
damaged, and that there is no visible leakage of water through the joint between the
diffuser and the base.
4. Do not hold the paddles while they are turning, or in any other way try to stop them
from rotating. This could cause injury or damage the drive mechanism. Turn the motor
switch off before placing the mixer module on the base or removing it.
5. Each air injection station has an on/off switch on the recycle module. Except when
being used for recycle injection, these switches should always be in the off position.
This will ensure that there are no unintended discharges of recycle water resulting from
accidentally pressing a start button or some other cause.
6. The saturator vessel is charged with compressed air during normal operation. Before
refilling the vessel, release the pressure by pulling the pull ring on the pressure relief
valve. Do not attempt to open the vessel until all pressure has been released. The
pressure relief valve has been factory set at 140 psi, and is not adjustable.
7. Do not operate the saturator with an insufficient quantity of water. Doing so could result
in a violent discharge of air from the saturator vessel to the injection nozzles, and
splashing of water from the jars. Before each run, check that there is an adequate
volume of water in the saturator. This can be gauged by the weight of the saturator
vessel, or by shaking it gently.

8. The main power supply to the unit is protected by a 2 amp fuse. Repeated failure of this
fuse indicates a faulty electrical condition and the equipment should be checked by a
qualified electrician. Do not replace the fuse with one of a higher rating.
