Congratulations on your purchase of a high quality, Australian made Sterio
Ultra Violet water treatment system. All components have been designed and
manufactured to give trouble free, reliable operation.
Your new Sterio system incorporates a lamp failure system design feature that
enables you to be warned of a lamp failure by :-
1. A lamp failure LED
2. An audible alarm
3. Remote alarm contacts
In addition when the alarm “beeps” on and off, the lamp is due to be changed so
that effective treatment is maintained.
Before installing your new Sterio, please read all instructions
carefully as failures caused by incorrect installation or
operation are not covered by the guarantee. Your Ultra Violet
water treatment system is designed to handle clean water.
The system should not be used for any other purpose without
specic referral to CCL. The use of the system with ammable,
corrosive and other materials of a hazardous nature is
specically excluded.
NOTE: The quartz sleeve
has been factory tted,
and there is no need to
remove these endcaps
on rst installation. Before
removing endcaps, please
read the Maintenance
section of these instructions
completely.
The appliance is not intended
for use by young children
or inrm persons without
supervision. Young children
should be supervised to

Preparing your system
On removing your Sterio system from its carton you should check all
components, especially the lamp, to ensure all are present and have not been
damaged in transportation. You should have:
1. Power supply control box with indicator light(s) and electrical ex
2. UV lamp (or lamps)
3. Treatment chamber with mounting brackets
Choosing a Site
Choose a site with a rm mounting position. Allow room for removal of the
lamp and sleeve during servicing. Leave a chamber lengths space at the lamp
connector end for lamp removal, with 100mm free at the other end for access to
the end nut. The ‘open’ end nut and the blank end nut are interchangeable, so
lamp removal can be from either end.
Housing your Sterio System
To protect your Sterio system from the weather, make sure the site is water
proof, frost free and has adequate ventilation. The unit should be either
horizontally mounted with the inlet/outlet facing upwards or vertically mounted
with the inlet/outlet at the bottom. Allow for drainage, to avoid damage to ooring
etc., that over time may occur from leaking pipe joints or seals and allow room to
remove the lamp.
WARNING: Some insects, such as small ants, nd
electrical devices attractive for various reasons. If your
site or enclosure is susceptible to insect infestation you
should implement a suitable pest control plan.

6
Power Connection
WARNING: When servicing or attending your Sterio,
always ensure power is switched off and lead
unplugged. Electrical connections should be serviced
only by qualied persons. If the electrical supply lead of
this system is damaged, it must only be replaced by a
qualied service personnel.
Connect lead to power supply designated on control box label. Earth stainless
steel chambers using bolt provided on the chamber (see illustration below).

7
Install the power supply enclosure above the treatment
chamber so that in the event of a leak, water cannot
drip down the lamp lead into the enclosure.
CAUTION: The supply cord is necessary for lamp
changing. The three pin supply plug must remain
accessible after installation. If installed to xed wiring
without the plug a two pole switch must be tted and
its ON and OFF positions shall be marked.
The Sterio control box has a red LED alarm indicator
light mounted on its front panel, adjacent to the amber
“power on” LED. This light will be illuminated whenever
the Sterio control box senses no lamp current. There
is also an audible alarm in the event of lamp failure. The
LED and/or alarm will only work when unit is connected
to the correct electrical supply.

8
Electrical Power Surge Protection
An electrical power surge or spike can travel on the supply lines and cause
serious damage to your electrical equipment. The Sterio control box has a 2 Amp
fuse
to protect the circuit. The fuse is not a lightning arrestor and may not protect the
Sterio if lightning or a very powerful surge hits the unit.
If the installation is subject to electrical power surges or lightning we strongly
recommend the use of suitable additional surge protection devices on ALL
electrical equipment.
We recommend the use of an RCD or earth leakage circuit breaker on the power
supply to your unit.
DO NOT LOOK AT UV LAMP WHILE LAMP IS
OPERATING Ultra violet radiation is harmful to
skin & eyes.
DO NOT DISASSEMBLE ANY COMPONENTS UNTIL YOU
HAVE FULLY READ THESE INSTRUCTIONS!
Pipe Connections
NOTE: Prior to installation remove the transport plugs
from the inlet, outlet and lamp end cap.
Never use PVC pipe directly connected to unit. PVC pipe and ttings can be used
after 90o bends of a suitable material are connected to the inlet and outlet of the
chamber. Larger diameter pipe may be used to minimise resistance to ow, but
maximum ow rates should not be exceeded, as correct water treatment cannot
be assured at higher ows. If ows may exceed the design maximum, install a
ow restriction device.
Do not use pipe thread sealing compounds (especially
hemp) on any part of this unit. ONLY use Teon
sealing tape.
Use unions at pipe connections to enable easy removal and servicing. Use
sufcient tape to ensure airtight seal and do not over tighten. To prevent strain on
unit threads always support heavy inlet and outlet pipes.

9
Pre-treatment (drinking water)
Pre-ltration is usually required to ensure that particulate matter does not shield
micro-organisms from the UV light. Sand ltration or 20 micron cartridge ltration
is the usual minimum. In some cases, particularly with surface water, ner
ltration may be necessary, or if cysts like Giardia or Cryptosporidium may be
present.
In this case 1 micron ltration is required, not necessarily for the whole supply,
ltration for the drinking tap only may be practical.
Lamp Installation
Once the Sterio Treatment Chamber has been connected to the pipework, the
installation should be checked for water leaks.
Attach the “DO NOT LOOK AT LAMP” sticker in an obvious position on the
treatment chamber, check that the chamber is clean to ensure the sticker will
adhere correctly.
The Quartz Sleeve is pre-installed in the treatment chamber, and provided the
endcaps have not been disturbed or undone, is able to withstand well in excess of
the maximum operating pressures.
If the chamber test is successful, it is now time to insert the lamp. DO NOT
INSERT THREE PIN POWER PLUG TO POWER OUTLET YET!
Expose the connection end of the lamp from its transport tube and protective
wrapping. The lamp connection socket is “keyed” to ensure correct alignment.
Carefully remove the tube fully from its transport tube, touching the lamp as little
as possible. Handle the lamp by the ends where possible. Wipe with clean cloth
and methylated spirits if ngerprints or dirt need removing.
Slide the lamp into the chamber, t lamp connection socket and then fasten the
end washer into the endcap, with the screws provided.

10
Operation
Once all leak testing and lamp tment has been completed, open valves and
allow water to ll the chamber. Connect three pin plug to outlet and switch on. The
“Mains On” Amber LED will be illuminated and the red alarm light will ash slowly.
Allow two minutes for the UV lamp to reach full intensity before starting water ow.
Full lamp performance for a new installation will be achieved in 24 hours. On a
new installation where no other form of sterilisation has been in constant usage,
we recommend ushing the pipework with a suitable sanitiser such as Steritank
HP (only available in New Zealand) or Acquasafe at 100mg/L. This solution
should be left in the piping for at least an hour and preferably overnight.
The Steritank HP or Acquasafe solution can be dosed to the water tank or if
necessary added as a shot dose to the bowl of any lter housing installed with the
UV system and slowly ushed into the piping.
If dosed to the water tank the Steritank HP or Acquasafe will be left in the water
as it is tasteless and suitable for use in drinking water. If added as a shot dose it
should be rinsed out through a nearby tap.
Davey Water Products Limited cannot accept responsibility for loss or damage
resulting from incorrect or unauthorised installations.
Maintenance
Lamp changing (every year of operation):
1. Shut valve(s) so that water cannot ow through steriliser
2. Switch off steriliser by unplugging mains
3. Undo end cover screws
4. Unplug lamp connector
5. Remove lamp
Reverse procedure when replacing lamp, ensuring that lamp is centrally located
in the chamber. Handle only by the ends.
