In addition to normal safety rules which should be observed with stationary
Ozone Generators and equipment, the following safety directions and pre-
cautions are of special importance.
When operating this unit, the operator must employ safe working practices
and observe all related local work safety requirements and ordinances.
The owner is responsible for maintaining the unit in a safe operating condi-
tion. Parts and accessories shall be replaced if unsuitable for safe operation.
Installation, operation, maintenance and repair shall only be performed by
authorized, trained, and competent personnel.
Normal ratings, pressures, temperatures, time settings, etc., Shall be dili-
gently adhered to.
Any modifi cation to the Ozone Generator, and/or related equipment, shall
only be performed in agreement with Azco Industries Limited and under
supervision of authorized, competent personnel.
If any statement in this book, especially with regard to safety, does not
comply with local legislation, the stricter of the two shall apply.
These precautions are general and cover several machine types and
equipment; hence some statements may not apply to the unit(s) de-
scribed in this book.
INSTALLATION
1. The Ozone equipment should only be lifted with adequate equipment in
conformity with local safety rules. Wear a safety helmet when working in
the area of overhead or lifting equipment.
2. Place the unit where the ambient air is as cool and clean as possible. If
necessary, install a suction duct. Never obstruct the air inlets. Care should
be taken to minimize the entry of moisture into the air inlet.
3. The unit shall be installed in such a way that an adequate fl ow of cooling air
is available.
4. Ensure that the rear exhaust vents are not in contact with or near to fl am-
mable materials.
5. All Azco products are designed to operate under vacuum. DO NOT operate
under pressure.
6. Install the equipment on a solid fl oor suitable for the weight, this applies to
all other equipment as well e.g. SPT’s and Foam Fractionator’s. If ground
is not level or can be subject to variable inclination, consult Azco Industries
Limited.

SAFETY PRECAUTIONS

OPERATION
1. ATTENTION: Please read the section labeled “First Start-up” prior to
operating the unit.
2. Air hoses shall be of correct size and suitable for the working vacuum/
pressure. Never use frayed, damaged or deteriorated hoses. Use only the
correct type and size of hose end fi ttings and connections.
(Caution: Use extreme care with the ozone gas lines when in operation, the unit must be
turned off before any of the ozone lines are disconnected. Carbon face masks should be
worn if an ozone leak arises.)
3. Never operate the unit when there is a possibility of taking in fl ammable
or toxic fumes.
4. Never operate the unit at pressures below or in excess of its limit ratings
as indicated on the product specifi cations sheet.
5. Keep all body panels closed during operation. Caution (High Voltage
inside)
6. Periodically check that:
• All hoses and/or pipes inside the unit are in good condition, se-
cure, and not rubbing
• There are no leaks
• All electrical leads are secure and in good order
• Air outlet lines are in good repair and free of wear or abuse.
MAINTENANCE
1. Maintenance and repair work shall only be done under supervision of
someone qualifi ed for the job.
2. Use only the correct tools for maintenance and repair work.
3. Use only genuine Azco spare parts
4. All maintenance work, other than routine attention, shall only be under-
taken when the unit is stopped, the main power supply is switched off and
the machine has cooled down. Take precaution to ensure that the unit
cannot be started inadvertently.
(In addition, a warning sign bearing a legend such as “work in progress; do not start” shall
be attached to the starting equipment.)
5. Never use fl ammable solvents or carbon tetrachloride for cleaning parts.
Take safety precautions against toxic vapors of cleaning liquids
6. Make sure that no tools, loose parts or rags are left in or on the unit.
7. Never use caustic solvents which can damage internal components and
materials. All responsibility for any damage or injury resulting from neglecting
these precautions, or by non-observance of ordinary caution and due
care required in handling, operating, maintenance or repair, even if not
expressly mentioned in this book, will be disclaimed by Azco Indus-
tries Limited.

Rear

Gas Line Plumbing
Plumbing of this equipment only requires the connection from the water trap (diagram 3) to the S.S. Ball
valve and then to the injection point. The Rear Orientation diagram shows all of the connections on the rear of the
RM900.
All connections to the water trap MUST use Tefl on® lined, Solid Tefl on® tubing, or 316 SS. The connections are as
follows,
1. Vacuum sensor port not present for use with RM900
2. Ozone-In ports. These ports are to be connected to the ozone generators’ ozone-out ports (#6 rear orientation).
3. Ozone-Out port(s). Connected to S.S. ball valve shown on the fl ow diagram on page 12 and then to the injector.
Physical Space
The RM900 is 590mm Wide by 750mm Deep by 1645mm Tall. This equipment is both air and water cooled and
thus requires space to allow the air to enter and escape. At least 30 cm (~12”) should be free from obstructions in
the front and rear of the machine. All controls and fan inlets are located in the front and rear and under NO circum-
stances is this to be obstructed. This equipment should be placed near a drain so that the water trap can be allowed
to expel access water before it reaches the sensitive electrical equipment (via the water trap).
AZCO Industries LTD. is not liable for water release due to a failure of any part or failure to control the external water
supply, The customer shall provide proper drainage of the space below the unit. Going beyond the pressure limits
may cause damage internally to the RM900 causing potential water leaks.
Environmental Conditions
A clean, well ventilated environment is vital to the equipment’s longevity. Major factors that should be consid-
ered when installing are as follows:
• Ambient Temperature must be maintained below 35 degrees Celsius.
• Ambient Relative Humidity must be maintained below 85% non condensing.
• Corrosive and oily vapors as well as dust must be kept to a minimum.
• Proper ventilation is also a must and can greatly help in keeping the above mentioned problems in check.
• The equipment must also be indoors sheltered from rain and other hazardous environments.
• An adequate supply of fresh air is necessary to prevent temperatures from building

Cooling Water Plumbing
Both inlet and outlet ports are located on the Back side of the ma-
chine Diagram 4. The inlet port (#2) is a 1/2 NPT female connection. The
outlet port (#1) is a 3/4” NPT female connection. It is critical to maintain
the fl ow in the correct direction for the safety of the equipment as well as
the potential output of the machine.

After verifying that all gas, water plumbing and electri-
cal connections are correct, you will be ready to turn on the
system for the fi rst time. The following steps and diagrams
are designed to make this initial start-up as quick and easy
as possible. Diagrams are numbered to correspond with the
steps below. Remember to use the ORIENTATION diagrams
for reference.
Step 1:
Turn on the main power to the RM900 by lifting the Cir-
cuit breaker (#1) on the back panel of the RM900.
Step 2:
Now that the main power has been turned on, you can
proceed to use the ON/OFF switch on the front panel (#10)
At this point the RM900 should have the status lights lit and
the main display turned on. The next series of steps will
involve preparing and/or clearing the status LED’s one by one
until we have all the conditions green and producing ozone.
Step 3 deals with the ORP settings.
Step 1:
Turn on the main power
Step 2:
Turn on the RM900
Step 3:
Adjust ORP Levels
• Hold “high” and press + or -
• Hold “Low” and Press + or -
Step 4:
• Plug in ORP Probe
• Override with jumper
