Prior to using this system you must ensure that:
• The system is installed in a safe and dry environment
• The system enclosure has adequate drainage in the event of leakage
• Any transport plugs are removed
• The pipe-work is correctly sealed and supported
• The pump is primed correctly
• The power supply is correctly connected
• All steps have been taken for safe operation
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 above
the lamp cover & connector end for lamp removal.
To protect your system from the weather, make sure the site is ood proof,
water proof, frost free and has adequate ventilation. Allow for drainage, to
avoid damage due to ooding etc., that over time may occur from leaking
pipe joints or seals.
POWER CONNECTION
Connect lead to power supply designated on control box label. Check that
the earth is connected to the stainless steel chambers using bolt provided
on the chamber.
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.
WARNING: When servicing or attending your Aquashield MAX, 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.
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.
NOTE:
a) For protection, the Davey® pump motor is tted with an automatic
“over temperature” cut-out. Constant tripping of this overload device
indicates a problem e.g. low voltage at pump, excessive ambient
temperature (above 50°C) in pump enclosure.
b) The Torrium®control device may have to be reset after rectifying any of
the above operating troubles. This is done by pushing in the “prime”
button and releasing it after 2 seconds, or switching the power supply
off then on.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction
concerning use of the appliance by a person responsible for their safety.

6
PIPE CONNECTIONS
For best performance use P.V.C. or
polythene pipes at least the same
diameter as the pump’s inlet and
delivery outlet openings. Larger
diameter pipe may be used to
minimise resistance to ow when
pumping longer distances.
Use unions at pipe connections to enable easy
removal and servicing. Use sufcient tape to ensure
airtight seal and hand
tighten only. To prevent strain on pump threads
always support heavy inlet and outlet pipes. If
there is a likelihood the water supply may contain
solid particles such as pieces of plant or vegetable
matter, a lter should be installed before the pump to avoid blocking of
water ways. Lay suction pipe at a constant gradient to avoid air pockets
which may reduce pump efciency.
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.
NOTE: Suction leaks are the largest cause of poor pump performance and
are difcult to detect. Ensure all connections are completely sealed using
thread tape only.
Do not use pipe thread sealing compounds on any part of this pump. ONLY
use Teon sealing tape.
NOTE: Prior to installation remove the transport plugs from the inlet, outlet
and lamp end cap.
Do not use pipe thread sealing compounds (especially hemp) on any part
of this unit. ONLY use Teon sealing tape.
RainBank® controllers can only be connected to mains water, by a qualied
licensed plumber.

PUMP CONTROLLERS
TORRIUM®
Your new system incorporates ‘Torrium®’, electronic ow controller – a
Davey designed unit that enables the use of a highly efcient pump design
and offers the following benets:–
1. Enables the pump to deliver a constant ow of water particularly at
low ow rates – reducing the inconvenience of pressure variation in
showers etc.
2. Provides automatic “cut-out” protection should the pump run out of
water or overheat*, should the pump fail to start due to low voltage or a
blockage in the pump.
3. Provides warning indications for critical and noncritical system faults.
4. Has adaptive pressure cut-in which allows the pump to start at
approximately 80% of the maximum pressure at last shut-down. This
allows the controller to accommodate varying inlet pressures and pump
performance.
5. Automatic retry functions in the event of a critical system fault.
* Motor overload / overheat protection included. Motor has its own overload
/ overheat protection.
Status Indicator
The Torrium®has a status indicator light on the front panel. This light will
enable you to understand what your pump is doing.
Condition Indicator readout Pump operation Restart / Reset Method
Standby mode Red light Standby Pressure drop

The electrical connections and checks must be made by a qualied
electrician and comply with applicable local standards.
The Davey Torrium® tted to this pump has a status indicator light mounted
on its front panel. This light will be illuminated whenever the Torrium®
senses that there is electrical power available. The light will only work
when unit is connected to the correct electrical supply.

8
Both the Red & Green Indicators are shown in the same window. It is
possible for the pump to be running (ie. Green indicator) and for a Red ash
sequence to happen at the same time. In that case the Red ash will show
as a Yellow or Amber ash.
Cistern Fill Mode
When your new HP or HS pressure system is used to ll toilet cisterns or
troughs, a special feature of the Torrium®controller may be activated. This
special feature is activated when the controller detects three quick stop start
sequences in a short period. When activated the status indicator will glow
“Amber”, and the pump will run on for two minutes before shutting down.
This allows the cistern to be lled with the minimum number of pump cycles.
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.
Only one fault condition will be indicated at once.
DO NOT DISASSEMBLE ANY COMPONENTS UNTIL YOU HAVE FULLY READ
THESE INSTRUCTIONS!
Ultra violet radiation is harmful to skin & eyes.
DO NOT LOOK AT UV LAMP WHILE LAMP IS OPERATING.

9
Auto-retry and Water Return Modes
Should your Torrium®detect a loss of prime, after stopping the pump, it will
wait ve minutes before activating Auto-retry and Water Return modes.
Auto-retry automatically starts the pump to see if the pump is now primed.
It does this after 5 mins, 30 mins, 1 hr, 2 hrs, 8 hrs, 16 hrs and 32 hrs.
Water return mode will restart the pump automatically if the Torrium®detects
water ow through it.
Priming and Operation
The Torrium® module tted to your HM or HS system is provided with a
push button “Prime” button. This button is used during initial priming of the
pump and also acts as a reset button if the Torrium®switches out in pump
protection mode.
1. Remove priming plug and ll
casing and suction line (on
ooded suction, simply open
gate valve to pump). When
full, replace priming plug.
2. Ensure outlet nearest
to pump is open.
3. Ensure all valves in suction line
are open.
NOTE: If multiple errors are present, the highest priority error (least number
of ashes) is indicated. Any previous fault code is lost until it recurs.
4. Switch on power - The
status indicator light
will be illuminated
green and the pump
will run. A full ow
of water should be
discharged from the
open tap.
5. If the pump stops with the
tap open see troubleshooting
checklist.
6. Close the open outlet or tap and
the pump should stop after a
few seconds (the status indicator
light should be illuminated red
(constant). If not, consult the
troubleshooting checklist.
To Reset if Pump switches out in
Pump Protection Mode
1. Make sure pump is primed.
2. Open tap, push prime button.
3. Close tap and pump will stop.

RAINBANK®– HOW IT WORKS
1. When there is demand for water from your toilet, washing machine or
garden tap RainBank®senses this demand and checks the level of water
in the rainwater tank. Note: demand must be greater than 1.5 litres per
minute or mains water will be delivered.
2. If there is rainwater in the tank RainBank® switches on the pump. The
pressure of the pump is sufcient to overcome the pressure of the mains
water inside RainBank®and this closes a dual check valve and allows
the rainwater to ow. Note: mains water pressure is limited to 300kPa.
3. When there is no longer a demand for water, RainBank®detects that
water has ceased to move inside the pipes, switches off the pump and
waits for another water demand.
4. If RainBank® senses a water demand and detects insufcient water in
the rainwater tank it will automatically allow the mains water to ow.
5. If there is a power failure during a demand for water RainBank®will
automatically supply the mains water as backup.
Fit oat switch to rainwater tank
IMPORTANT
• The level switch is suitable for installation in polyethylene and breglass
tanks. It can be tted in steel tanks but cutting through the zinc alum
or colourbond coating of the tank exposes bare steel and this can rust.
Check with the tank manufacturer before drilling.
• The oat switch is designed to be installed from the outside of the tank.
There is no need to get inside the tank.
• The sealing grommet of the oat switch is designed to work in a maximum
tank wall thickness of 25mm. It is not suitable for concrete or very thick
plastic walled tanks. There is an alternative oat switch that can be
lowered into the top of these types of tanks (Davey Part Number 13449).

Work out the correct position for the hole for the
oat switch. With a corrugated prole tank wall this
is on the upper at section of the prole as shown
below.
Work out the correct location of the oat switch
relative to the pump outlet.
The oat switch location should also be:
• At least 40mm above the pump inlet.
• Placed away from the rainwater entry into the tank so that the incoming
ow does not interfere with the operation of the switch.
Before cutting the hole check again that the 5m lead from the oat switch
will reach the RainBank®and plug comfortably into it.
1. Drill a 22mm hole in the side of the tank in the
correct position. A hole saw is the best tool for this
job. Ensure all swarf is removed from the hole.
If installing the switch in a corrugated tank you
should make sure that it is installed on the at
section between the radii as shown below.
2. Ensure the compression nut is loosened so that
the sealing grommet is not expanded. Remove
the sealing nut and insert the switch into the hole
as below.
3. The switch will not work properly if it is not
properly orientated. Make sure the word
“UP” is seen at the very end of the switch
body. Now tighten the compression nut to
expand the seal (as shown below).
4. Ensure that the switch is still correctly
orientated. With the word “UP” visible, screw
on and tighten the sealing nut to nish the
installation of the oat switch.

Test the operation of RainBank®.
1. With the mains connected and the rainwater tank empty turn on one of
the taps in the laundry that feed the washing machine or ush the toilet.
Mains water should ow normally. The pump should not turn on. When
this is completed turn off tap.
2. Fill the rainwater tank with sufcient water to activate or cover the oat
switch.
3. Check that the pump is correctly primed and there are no air locks that
will interfere with its operation as per the Davey instructions. This is
essential for the proper operation of the unit. See the instructions on how
to do this for all types of Davey pump in the Priming section on page 26.
4. Turn on a tap or ush a toilet in the rainwater system. The pump should
run and deliver rainwater. Allow to run for several minutes to clear air
from pipes.
5. Remove the oat switch connection from the RainBank®– this should
stop the pump and conrms that the oat switch and power connections
have been made correctly - ret the oat switch connection. Press the
manual override button to operate the pump if needed.
6. Check for leaks around RainBank®, the pump, pipework and ttings.
IMPORTANT: To allow easy connection it is strongly recommended that you
have exible copper pipes that allow some movement so that they can line
up exactly with the mains water and rainwater outlet. These pipes must be
3 ⁄4 inch in diameter.
IMPORTANT: It is highly recommended that an isolation valve be tted to
where the mains water enters RainBank®and between the pump and the
rainwater tank. This facilitates easy removal of the unit if required without
turning off the household water or losing stored rainwater.
NOTE: Do not instal additional suction check valves on RainBank®systems
except where a foot valve is required (eg. suction lift installations). In the
case of suction lifts, to allow for the correct operation of your RainBank®
and for movement of the tank and pump which may occur over time, the
suction pipe must have a length of exible suction hose from pump to
top of tank. This hose can be braided hose, reinforced suction hose or
polythene pipe at least 1 metre in length.

13
PRE-TREATMENT (FILTRATION)
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, this is provided in Stage 1 ltration.
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, as provided in Stage 2 ltration.
Temperature Rating
Maximum 50oC - Minimum 8oC
Sediment Cartridge Filter Life
Once the housing is properly installed, a reduction in ow/pressure (to
such an extent as to cause inconvenience) will indicate when the cartridge
is becoming clogged and needs replacing/cleaning. Sediment cartridges
should be replaced/cleaned/sanitised when the water ow has been
noticeably reduced/or after 3-6 months - whichever comes rst (this is for
hygiene reasons).
Changing the Filter Cartridge
1. Turn off the valve to stop the ow of water.
2. Release the pressure by opening a tap downstream, or use the
pressure relief valve that is available in the lid of some lter housings.
3. Unscrew the bottom housing from the lid and pull out the used cartridge
and discard or wash. The inside of the lter housing and the lid should
be checked for cleanliness - they will usually need to be cleaned or
sanitised - use hot water and dishwashing liquid, thoroughly scrub all
surfaces and then rinse.
4. Check that the oring is in position in the top of the housing base,
lubricate with a coating of white petroleum jelly (Vaseline), place the
Caution: The housing must be protected against freezing. Failure to do so
may result in cracking of the housing and water leakage.
NOTE: Actual ltration/purication life of cartridge can vary with the
condition of incoming water.
NOTE: Clean lter Stage 1 once a pressure drop of 100 to 150kPa from
clean, or between Stages 1 and 2.
WARNING: CAREFULLY AND GENTLY TIGHTEN WITH HOUSING SPANNER
as the bowl should only be tightened enough to avoid water leaking
during operation.
WARNING: If the water system is not going to be used for extended
periods, the cartridge should be removed from the housing and replaced
with a new or cleaned cartridge when the system is used again.

14
IMPORTANT: When opening the lter housing to install or change the
cartridge (element) it is common for the oring seaI to lift out of the groove
and, at times, it may even stick to the cap.
CAUTION WHEN INSTALLING
1. This is a plastic product with a female thread. If you cross-thread a
male tting, and/or you over pack with sealing tape, you could do
permanent damage.
2. If you use a tapered thread male tting do not over tighten.
3. No warranty claims will be considered for damage due to incorrect
installation.
oring into the groove and with two ngers wipe the oring down into the
groove. Do not wipe the oring clean of lubricant after it has been properly
seated in the groove because the lubricant prevents “crawling” of the
oring during the tightening of the lid and thus prevents water leaks.
5. Screw the housing onto the lid and hand tighten. Open the tap
downstream of the lter and then open the inlet valve.
STERIFLO®
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.

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.
Connect lead to power supply designated on control box label. Check that
the earth is connected to the stainless steel chambers using bolt provided
on the chamber.
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 appliance is not intended for use by young children or inrm persons
without supervision. Young children should be supervised to ensure they do
not play with the appliance
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 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.

16
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.
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 at 100mg/L. This solution should be left in
the piping for at least an hour and preferably overnight.
The Steritank 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 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 can not accept responsibility for loss
or damage resulting from incorrect or unauthorised installations.

17
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.
Quartz Sleeve Cleaning :
If dirt is allowed to build up on the quartz sleeve it will impair the UV output.
The quartz sleeve should be removed after one month and inspected for
deposits. Clean with calcium lime and rust remover (CLR). Apply some
CLR to a soft cloth and wipe the quartz sleeve. Once clean, wipe any
residual CLR off with a wet soft cloth. Handle the sleeve with tissue to keep
it clean. The sleeve should be cleaned every three months or as required.
Sleeve removal (use care-fragile) :
1. Remove lamp as described.
2. Remove drain port cap and empty water from chamber.
3. Undo nut at one end of the chamber and remove o-ring, repeat with nut
at other end and remove o-ring, withdraw sleeve carefully.
4. Inspect o-rings for damage, replace annually.
CAUTION: Handling lamp and quartz sleeve. Keep the quartz components
free of nger marks to avoid loss of output through dirt or grease shadows
- handle the lamps by their ends where possible. Wipe lamp and sleeve with
clean cloth or tissue if needed. The o-rings should be replaced annually or if
damaged – do not grease the o-rings.
NOTE: When withdrawing sleeve take care not to let the end drop into the
chamber as it could break - a clean dowel inserted right through the sleeve to
support it is useful.

18
MAINTENANCE CONTINUED...
Reverse procedure when replacing sleeve.
When replacing quartz sleeve after cleaning, the sleeve should stick out
about 1cm at each end. Place o-ring over closed nut end and t closed nut,
fastening it hand tight. Hold the other end of the sleeve in position during
the tightening with the other hand, then t open end o-ring and cap.
A tiny amount of silicon spray or CRC in the end of aluminium endcap
threads will aid easy tightening. Do not use excessive force when tightening
nuts. Do not re-use quartz sleeve or o-rings if damaged.
WATER QUALITY
Where the water being pumped contains unusually high levels of dissolved
solids (hard water), iron, manganese or biological organisms, a deposit
build up on the quartz sleeve may occur over time. This will compromise
the effectiveness of the UV system and the sleeve should be cleaned as
required to maintain it in a clean condition. Discoloured water will reduce
the effectiveness of the UV system and ltration should be installed.
LAMP ALARM SYSTEM
If the UV lamp is out due to a failure or bad connection the alarm buzzer
will sound and the red LED will light and the alarm will disconnect power
from the pump preventing untreated water from being delivered. The alarm
function can be checked by switching the unit off, disconnecting the lamp
and then switching the unit back on.
The lamp should be replaced after a year’s running time. The alarm will
beep intermittently after the internal clock has measured this time as a
reminder to change the lamp. Pressing the recessed ‘reset’ button with
a ballpoint pen will silence it for 24 hours at a time to allow time for a new
lamp to be obtained. Once a new lamp is installed press the reset button for
5 seconds to start another year’s timing. Do this whenever a new lamp is
installed. The alarm light ashes slowly during normal operation to show the
timer circuit is running.
If alarm sounds when new lamp is inserted, turn power off for ve minutes
to allow for internal reset of the power supply.
