Saphir Range
Description
The units are designed for the ultraviolet disinfection
of water between 5°C and 23°C and can be fitted
anywhere in a water system provided the maximum
pressure and peak flow requirements are less than
the maximum ratings (see specifications). The slower
the water flow, the more effective the unit will be. The
unit must be protected from frost when not operating.
For ease of maintenance, fitting stopcocks, a bypass
pipe and a drain tap with the unit is recommended.
For single-pass applications, it is best to install the
unit close to the point of use, removing the need
to store large volumes of treated water. If a storage
tank is used it must be closely covered and should
be cleaned and sterilised when the UV unit is fitted.
To ensure the water does not become stagnant the
tank should store no more than a few hours of water
supply.
Safety
• UV light can harm eyes and skin. Never operate the lamps outside of the chamber.
The units are safe when in normal use.
• Read the instructions fully before use – maintenance must only be carried out by
competent individuals.
• Do not operate the unit if any part appears damaged.
• The stainless steel chamber must always be earthed.
• Water and electricity are a dangerous combination - it is essential that there are no water leaks
in or around the unit that could result in the electrical system becoming wet.
If such a leak occurs, do not touch anything electrical when either it, or your hands are wet.
1. Switch off the power at the mains supply point
2. Switch off the water at the mains supply point
3. Find and fix the leak
4. Completely dry the unit and control box (inside and outside) before reusing

The lamps used in the Saphir Systems are filled with
gas and mercury vapour at low pressure. Although
they will not explode if broken there is a toxicity risk
from mercury contaminated glass.
In the unlikely event that mercury is released from a
broken lamp, evacuate the area and ventilate it. Seek
professional help to clean up the spilled mercury.
Do not use a vacuum cleaner as this will heat the
mercury causing it to vaporize and create a greater
widespread hazard.
Daro UV Systems provides a lamp replacement
service which includes the safe disposal of the
used lamp. Please contact our head office for more
information.
Safe Disposal and Risk Due to Damaged Lamps
Water Quality and Filtration
Ultraviolet light penetrates cloudy or coloured water
much less than clear water, therefore, it is essential
to ensure the water is clear before UV treatment.
A filter removing particles down to 5-10 micron in size
will normally ensure the water is suitable and such a
filter must be fitted, unless the water is known to be
completely clear at all times. Filtration will also extend
cleaning intervals. Dissolved organic matter and metallic
salts, mainly iron, will also absorb UV light and reduce
the unit’s effectiveness. If parameters exceed the EEC
maximum admissible concentrations, suitable pre-
treatment should be used to ensure water purity and
effective UV treatment. Individual sites and requirements
vary. Therefore, a site survey is recommended to
determine the necessary ancillary equipment and filtration
required before the UV equipment can be specified. If in
doubt, please contact the manufacturer for advice.
Materials
• The water chamber is made of 316 grade stainless
steel throughout.
• Lamps are isolated from the water chamber by a
quartz sleeve - an O-ring and plastic shim provides
a seal at the top end of the chamber.
• A separate control box houses the lamp control
gear and monitoring equipment.
• A splashproof cover provides protection to the
lampholder connections on the chamber.

Installation
Installation must be carried out prior to making any
electrical connections. See the general arrangement
drawings, supplied at the end of this document.
Chamber Mounting
The unit can be mounted horizontally or vertically,
however, consideration should be given to the following:
Chamber
Before installing the unit, check the tightness of the
quartz clamp. Using the key provided, ensure the clamp
is tightened to 4Nm torque setting. (This is equivalent to
a firm hand tight.)
Vertical Mounting
Water should enter at the bottom and exit at the top.
Lamp access should be uppermost with a clear space
equal to the length of the chamber at the end to allow the
removal of lamp or quartz during routine maintenance.
Horizontal Mounting
Water should exit at the top. If this is not possible, it may
be necessary to fit a non-return valve or an automatic
bleed valve to prevent air pockets, as a significant air
space in the chamber will reduce its effectiveness.
A clear space equal to the length of the chamber should
be left at the end to allow the removal of lamp or quartz
during routine maintenance.
Control Box
The control box can be mounted either to the UV
chamber or to the wall directly. If it is chamber
mounted horizontally, arrange the wall brackets
to be approximately central to the chamber. In all
cases ensure it is positioned so that the lamp cable is
not stressed.
Saphir 1 including Saphir+ and Saphir Pro versions
• Fit the two wall-mount brackets (B) to the wall.
pace apart by about ¾ of the length of the chamber,
with the slots uppermost, using the correct screws
for your wall type (screws not included).
• Open the worm-drive clips to their maximum and fit
over the chamber. Place the chamber on the wall
brackets, slip the clips into the slots on the brackets
and tighten.
• For chamber mounting of the control box, loosen
the worm-drive clip by the lamp holder, fit the slot in
the control box foot over the drive strap and tighten.
• Secure the other end of the control box to the
chamber with the third worm-drive clip.
• For remote control box mounting, mount the
chamber as above. Fit the control box wall brackets
through the slot in the control box feet and screw
directly to the wall.
Saphir 2, 3, 4 and 7 including Saphir+ and Saphir
Pro versions
• Fit the two wall-mount brackets (B) to the wall.
Space apart by about ¾ of the length of the chamber,
with the slots uppermost, using the correct screws
for your wall type (screws not included).
• Open the worm-drive clips to their maximum and fit
over the chamber. Place the chamber on the wall
brackets, slip the clips into the slots on the brackets
and tighten.
• For remote control box mounting, drill four holes
on a grid of 180mm x 140mm (depending on the
required orientation) and fit four off no. 6 screws.
Use the keyholes to mount the control box.
• Where the control box is mounted on the chamber,
undo the third worm-drive clip and thread it
through the two slots on the rear of the control box.
Re-engage the clip around the chamber and
tighten.
Saphir 10 including Saphir+ and Saphir Pro versions
Use the pipe clips provided to secure the Saphir 10
chamber to the wall. Fit the control box as described
above, for types 2, 3, 4 and 7.

Electrical
This unit must be installed by a qualified electrician.
The Saphir range is supplied with a standard, BS1363
UK mains plug and should be connected to an
earthed 220-240V, 50-60Hz, single phase and neutral
supply, via a 3A fused socket.
The control box is provided with a trailing earth
lead – this must be connected to the stud on the
chamber body. If the installation of the chamber has
interrupted a water pipe, bond these together again.
If the UV lamp is switched off at any point wait for
approximately 30 seconds for the electronics to
discharge before switching it back on.
Volt Free Contact Connections
(Saphir+ and Saphir Pro only)
A 4-way (3-ways plus earth) connector is supplied
to mate to the control box volt-free contact socket.
If required, a length of suitable three-core plus earth-
control cable should be used to wire between the
connector and the remote equipment. A junction box
may be required to make the connection.
No voltages are connected internally to the relay –
this must be done via the cable plug. The relay drives
when the lamp is working correctly.
The socket is capped if this feature is not used.
See specifications, below, for relays ratings.
Connections
Terminal 1 - relay common. Connect to supply.
Terminal 2 - relay normally closed. Supply output
when lamp has failed.
Terminal 3 - relay normally open. Supply output
when lamp is OK. Connector Terminal 4 – earth. This
terminal is bonded to earth inside the control box.
Indicators and Controls
The Saphir+ range has the following features:
• Switch to reset the internal hour counter (see
maintenance, lamp replacement).
• Three-way indicator display showing the status of
the system.
• Alarm to warn of lamp failure and end of lamp life,
this can be temporarily silenced.
• Volt-free contact output for remote display of lamp
on indicator (see specification).

Saphir Range

01787 370187 |[e-mail] |darouv.co.uk
The lamp will continue to operate after 12-months of
running time, but the UV output will be reduced, and it
will be more likely to fail as it continues to age.
It should be replaced after 12-months use.
To turn off the audible alarm for 24-hours: press and
hold the reset button for one second, until a single
bleep is heard. This works in both alarm settings;
lamp fail and lamp lifetime.
The alarm will restart 24-hours later but can be muted
again if required.
Note: If the lamp has failed and the lifetime has
expired the three-second alarm sequence will begin.
The display gives an indication of the age of the lamp.
The lamp-on and lamp-status indicators will flash off
for a half-second period once every minute.
The number of flashes show how many year quarters
(three months) have passed, before the lamp-status
indicator alternates from green to red in the twelfth
month.
Age of Lamp Number of flashes
One to three months (first quarter) 1
Four to six months (second quarter) 2
Seven to nine months (third quarter) 3
Ten to eleven months (fourth quarter) 4
Twelve months and over None
Maintenance
The lamp gradually deteriorates during use and must
be changed at regular intervals. It is not possible to
measure the level of UV being produced by the lamp
by visual inspection. Therefore, a regular routine of
lamp replacement is recommended to ensure effective
performance. (see specification for lamp life.)
To replace the lamp:
1. Switch off electrical supply at the unit.
2. Remove the bayonet lampholder cap. Carefully,
partially withdraw the lamp, still connected to the
lampholder, from the chamber.
3. Whilst supporting the lamp disconnect the lampholder
from the lamp and gently slide the lamp straight out of
the quartz sleeve without applying any side pressure.
4. Warning - levering the lamp against the quartz will
result in damage to the sleeve.
5. Reverse the above to fit new lamp.
6a. To reset the hour counter for Saphir+
i) Turn the unit on.
ii) Press and hold the reset button for eight seconds
to activate the reset function. The lamp-on and lamp-
status indicators will flash four times to show the reset
has been successful. (Once the indicators start to
flash, the switch can be released.)
6b. To reset the hour counter for Saphir Pro
i) Reset switch cycles (“switchcycles” on menu, press
the white button to clear, press the red button to confirm.)
ii) Reset UV sensor reading (“adjust” on menu, press
the white button to select “yes”, press the red button
to confirm.)
iii) Scroll to “config”, press the red button to confirm.
The new settings will be applied.

Cleaning
In the event that sediments build up on the surfaces
of the quartz sleeve occasional cleaning will be
required. This is dependent on the nature of the
water supply and its pre-treatment; therefore, no firm
guidelines can be given on how regular this is will
be needed. Less sediment may be experienced when
the unit is vertical. The unit should be inspected after
a few months use to give an indication to the amount
of cleaning necessary. Where possible look into the
unit using a torch once the lamp has been removed.
Where this is not possible the quartz sleeve will need
to be removed as follows:
1. Turn off the power and remove the lamp as above
2. Turn off the water supply, isolate the input and
output and drain the unit
3. Unscrew end seal; remove the shim and O-ring
seal. Remove the quartz tube. Note: Care must
be taken when removing quartz tube, as it is not
supported inside the chamber. To avoid breakage,
it must be kept parallel with the axis of the unit
when being changed
4. Clean the outside of the sleeves using a mild
abrasive such as wire wool or domestic scourer -
a 10% solution of citric acid will help remove any
hard deposits. Vigorous scrubbing will remove
scale but will not scratch the quartz sleeve. When
the quartz is clean, the friction experienced when
cleaning the sleeve will be dramatically reduced.
Do not use an industrial scourer, as these grades
may be impregnated with abrasives which may
damage the sleeve surface
5. Do not attempt to clean the inside of the quartz
sleeve – they are sealed in normal use and this is
unnecessary
6. Replace the O-ring, the shim washer, and tighten
the seal with firm hand pressure and another
quarter turn
7. Dry the unit. Turn on the water and check for leaks
8. Replace the lamp and switch on
Note: Care must be taken when handling the quartz
sleeves
