PRE INSTALLATION INFORMATION
Check Contents
Separate all parts from the packaging and check you have each part according to the
pack contents section, pages 4-6. Pay attention to the variations of the different models.
Make sure all parts are accounted for before discarding any packaging material.
If any parts are missing, do not attempt to install your electronic tap.
Please call 0800 0723 404 immediately to notify us.
Warning
1) To avoid reflection problems keep a distance
of more than 300 mm. between the sink and the
spout.
2) This tap model, with an infrared sensor
pointing down, is not intended to be used
together with a sink of a reflective material such
as stainless steel.
3) If a sink strainer is straight below the tap
sensor, use a strainer with a non reflective finish
(do not use a chrome plated one).
Preparation for installation
Flush water supply lines thoroughly before installing the tap.
Do not allow dirt, Teflon tape or metal particles to enter the tap.

Important
All plumbing is to be installed in accordance with applicable codes and regulations.
6 | Dolphin Blue | 400 Series
PRE INSTALLATION
Warning
● To
avoid reflection problems it is recommended to keep a distance of more
than 300mm between the sink and the spout. If the distance is below 300mm
a simple mock-up should be effected to confirm the tap functions as desired
in your application before final installation. You may require a Dolphin Blue
remote control to adjust the range.
● Do
not connect water or power supplies or remove the black label
covering the infra-red sensor until you have read and understood
these instructions. Please see page 13.
● It
is not recommended to use DB400 series with a polished stainless steel
sink. For this type of application a separate panel-mounted sensor should be
used – please speak to our technical sales team.
● Please
observe the guide to minimum cavity depths as shown in the table.
This is important because the water supply hose must not be kinked due to
lack of space. Please note we have provided this information as a guide and
cannot be held responsible for fundamental design errors. If your situation
differs to those shown below please call us on 0800 0723 404, and we will
provide you with a solution.

Tap Solenoid Inspection Instructions
User Manual
Please read carefully before use
DOLPHIN
Tap Solenoid Inspection Instructions for Panel Mounted Taps
Turn off water supply before removing the solenoid.
Unplug the solenoid connector (red arrow)
Unscrew the solenoid (yellow arrow)
Please ensure that the flow direction arrow (green circle) is pointing towards the tap. The solenoid
WILL NOT WORK if the fitting is reverse plumbed! The tap will continuously flow at a reduced rate.
The diaphragm is then accessible.
It can be seen that leaking can be caused by very small particles. The larger the particle the faster
the tap will be leaking.
Remove the diaphragm and inspect very closely for particles on the surface, and clean.
Take care not to lose the piston in the centre of the solenoid housing.
The solenoid seating in the tap body should also be checked for particle ingress.
The piston should click and hold down when pushed into the solenoid. If the tap has been leaking a
steady stream of water it is very likely to be that the piston spring has become dislodged.
If the piston does not hold in the depressed position it should be carefully removed to reveal the
small spring beneath it. If it is lying on its side across the base, rather than standing upright as
shown, it should be removed with a small slotted screwdriver.
Do not deform the spring but allow the coils to grip the screwdriver blade.
Occasionally there is no debris causing the leak but the spring needs to be carefully stretched 1mm
to give increased pressure on the diaphragm. Take great care not to deform the spring.
Replace the piston with the spring inserted into the piston base.
Holding the solenoid housing upside down, and inserting the piston swiftly will assist this operation.
The solenoid housing should then be reassembled and replaced in the tap body.
If the tap is still leaking please recheck the diaphragm for particles as the smallest contamination will
cause leaking. Also wipe the diaphragm to remove any greasy deposits that may be present.
A new diaphragm should be fitted if the tap is still leaking after thorough inspection and cleaning.

Dolphin Blue
Infrared Systems Important Design Tips
DOLPHIN
Dolphin Blue Infrared Systems
Designing a washroom including Dolphin Blue Infrared Systems
Dolphin Blue Infrared Taps, Shower Controls and Urinal Flush Valves offer
significant water and energy savings. However, there are some simple
DO’s and DON’Ts and TIPs which will help avoid 99% of the situations
often associated with infrared systems for washrooms.
It should be noted that these details are not exhaustive but will help
eliminate 99% of situations. It is recommended that for larger projects
especially where design restraints will result in taps being set on minimum
or maximum settings, we would advise a very simple mock-up be set with
materials to be used to ensure infrared device operates as desired.
DO’s
Battery Back up
Pressure
DO include a battery back-up device when
installing a transformer powered infrared
tap in an accessible washroom.
DO ensure the static and dynamic pressure
at the Dolphin Blue device is within the
tolerances stated on the product literature /
data sheet (please ask if you cannot find it).
Most devices are tested to operate between
0.5 and 8 bar. If pressures are outside the
stated tolerances please contact the
Technical Helpline on 01424 20 22 24.
Security Time
DO ensure security time is set at
approximately 20 seconds on infrared taps
especially in locations susceptible to
vandalism. Also important: to be set at 20
seconds to comply with ECA/WTL
scheme.
Flow Rate
DO specify what flow rate is required when
placing your order.
Taps - 6 litre / minute is standard. 4 litre /
minute is readily available.
Filters
Do ensure filters supplied with the Dolphin
Blue device are installed. It may not be
sufficient to rely on the filters often included
with thermostatic mixing valves as the
gauge of the filter mesh may not be fine
enough. It is also important to ensure
pipes are flushed prior to connection and
filters are inspected on a regular basis.
Time between inspections will depend on
hardness and quality of water.
Shower head - 9 litres/ minute is standard,
8 litres / minute is available.
Distance from Transformer
Please speak to the Dolphin Technical
Helpline for other flow rates if required.
It is recommended you ensure the
maximum distance between a Dolphin
Blue Infrared Tap and its power source is 5
metres.
DON’Ts
Mirrors
Panel Mounted Infrared Taps
It is not advisable to locate a Dolphin Blue
Infrared device directly opposite a mirror
where the infrared eye faces the mirror in
such a way that it could reflect itself as this
can cause false activations
even if the mirror is 2-4 metres
away from the infrared eye.
It is very important to ensure the distance
between the sensor and the bottom of
basin when installing a panel mounted
Dolphin Blue Tap with an integral sensor is
a minimum of 300mm
above the bottom of the
basin.
Two Infrared Taps
It is not advisable to locate
infrared taps directly opposite
each other where the infrared
eyes face each other as this
can also cause false activations
even when there is a fair
distance between them.
TIPs
Minimum 300mm
distance critical
Polished Traps and
Sink Surfaces
When installing a Dolphin
Blue Panel Mounted Tap
with an integral sensor it is
recommended that you
avoid a highly polished
chrome trap or sink
surface –
it will act like a mirror to
the tap sensor, potentially
causing false activations
and wasted water
Avoid polished/
chrome strainers
High Visibility Clothing
‘Tall’ Version Taps and Spout Lengths
It is a feature of most infrared devices in
the washroom market that the reflective
strips on high visibility clothing may cause
the device to operate, even if someone just
walks past, with no intention of using it.
Consider the position of the water outlet /
aerator in relation to the basin.
The DB51 Dolphin Blue Remote Control
can be used to reduce the range of a
device to reduce these false activations
but may not eliminate the phenomena
completely.
Please feel free to discuss
spout lengths with the
Dolphin Technical Helpline on
01424 2022 24.
