Introduction
The Siren product range includes an exposed or a concealed valve complete with an adjustable height shower head.
Siren valves feature a single lever control to turn the shower on and off and to control temperature.
Siren thermostatic valves provide close temperature stability and fail safe protection on appropriate high and low
pressure systems. Please refer to the product specification section below.
If at any stage during installation you have any questions, please contact the Aqualisa customer helpline
on 01959 560010 for assistance.
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply
Regulations.
THE SHOWER MUST NOT BE USED WITH A HOT WATER SUPPLY TEMPERATURE OVER 65ºC.
The Siren range is designed for domestic use only.
Product specification
Siren products are suitable for all gravity, boosted gravity, balanced high pressure and combination boiler systems*.
Pressure range 0.1bar – 10bar max (static).
*The combination boiler MUST have a minimum rating of 24kW (80,000 Btu) and be of the type fitted with a fully
modulating gas valve.
If any doubt, please contact the appliance manufacturer before installation commences.
When fitted to combination boiler systems, Siren shower valves have been designed to give optimum temperature
control and stability from fully modulating combination boilers and instantaneous gas water heaters. The Siren
valves are supplied complete with flow regulators to control the incoming hot water flow rate into the cartridge.
The following regulators should be fitted to suit the relevant rated appliance as listed below:
YELLOW = 24kW (80,000Btu)
GREEN = 28kW (100,000Btu)
BLUE = 35+kW (120,000+Btu)
Please refer to pages 12 and 15 for fitting the regulator instructions.
Connections
Siren products are designed for conventional supplies with HOT on the left and COLD on the right as viewed from
the front.
Siren shower valves incorporate 15mm compression fittings. Tube should be cut using a rotary type cutter.
If plastic pipe is used, the tube insert must not increase the tube diameter or extend the cut off length by more
than 2mm.
Supply lines must be flushed clear of any debris before installation of the unit. Any debris accumulation in the
shower valve and head may result in damage and poor performance.
Important information
Siren 2 installation guide:Dolphin install Guide 17/1/11 10:27 Page 4

Pipe sizing
Long pipe runs, on both inlet and outlet, will reduce the flow rate at the shower head. If long pipe runs are
unavoidable, use copper pipe rather than plastic. If plastic pipe is used, minimise the number of elbows as pipe
inserts are very restrictive. Consideration should be given to using 22mm plastic or copper pipe especially if a
diverter valve is to be fitted.
Flushing
Some modern fluxes can be extremely corrosive and, if left in contact, will attack the working parts of the unit. All
soldering must be completed and the pipe work thoroughly flushed out in accordance with current Water Supply
Regulations prior to connection of the product.
Filters
To ensure ongoing optimum performance, Siren products are protected by inlet filter assemblies in the internal
waterways. Debris accumulation may result in reduced flow from the shower head and noisy operation.
As this condition is not covered by our standard warranty terms, it is suggested that the filters be removed and
checked by a competent person. In the event of any difficulties please contact the Aqualisa customer helpline
for assistance.
Isolating valves
Suitable full way isolation valves must be fitted to both supplies in accordance with current Water Supply
Regulations and our terms of warranty.
Due to their restrictive characteristics, stopcocks and ball type valves that reduce the pipe bore size must not be
used on gravity and boosted gravity installations.
Pressures
The Siren cartridge is designed to operate from the mains at a maximum of 10bar. If the mains pressure is likely to
exceed 10bar, a ‘drop tight’ PRV must be fitted on the supply pipe after the main stopcock. A setting of 3bar is
recommended. It should be noted that daytime pressures approaching 8bar can rise above the stated maximum
overnight.
A suitable PRV is available from Aqualisa.
Siren products are not suitable for mixed supply systems, e.g. gravity hot and mains cold.
Gravity fed hot and cold supplies
Services must be installed according to good plumbing practice having regard to pipe sizing, long pipe runs and low
head situations.
The cold supply for the valve assembly must be taken directly from the cold water storage system. The hot supply
may be taken from the vent/draw off pipe of the hot water cylinder at a point below the cylinder connection or
alternatively from the underside of the horizontal draw off.
Rising pipe work must NOT be connected into the horizontal draw off from the cylinder or to any point in the
vent/draw off pipe above the cylinder connection.

6
CYLINDER TEMPERATURE IN EXCESS OF 65°C MAY RESULT IN POOR SHOWER
PERFORMANCE
To minimise pressure loss we recommend that the hot and cold supplies are run in 22mm as close as reasonably
possible to the mixing valve before reducing to 15mm.
Siting
For optimum performance, with gravity fed systems the distance between the bottom of the storage cistern and the
shower head should be not less than 1m (when using an adjustable height head). If using a fixed head, the highest
point of the pipe work must be below the underside of the cistern.
Please refer to the typical system layout on page 8.
Pump installation
UNDER NO CIRCUMSTANCES MUST A PUMP BE FITTED DIRECTLY TO THE WATER
MAIN
A pump must only be used to boost the pressure from tank fed supplies.
A minimum 1 bar twin ended booster pump is recommended.
ENSURE THE MINIMUM GRAVITY FLOW RATE IS SUFFICIENT TO OPERATE THE PUMP
FLOW SWITCHES.
PLEASE REFER TO THE MANUFACTURERS PUMP INSTALLATION GUIDE FOR PUMP
INSTALLATION INFORMATION.
Please refer to the typical system layout on page 8.
Stored water capacities
The minimum capacity of the cold storage cistern should be not less than 225 litres (50 gallons). The capacity of
the hot cylinder must be capable of meeting the anticipated demand.
Combination boiler/multipoint system
Siren products are suitable for use with combination boiler systems. The combination boiler MUST have a minimum
rating of 24kW (80,000 Btu) and be of the type fitted with a fully modulating gas valve. This is sufficient to operate
one outlet at a time.
If in any doubt, please contact the appliance manufacturer before installation commences.
The cold supply can be taken from the nearest convenient mains supply and the hot supply can be taken from the
nearest hot water draw off point. Account must be taken of the pressure drops that will occur when other draw off
points are used while the shower is in use.
Please refer to the typical system layout on page 9.
When fitted to combination boiler systems, Siren shower valves have been designed to give optimum temperature
control and stability from fully modulating combination boilers and instantaneous gas water heaters. The Siren
valves are supplied complete with flow regulators to control the incoming hot water flow rate into the cartridge.

GREEN = 28kW (100,000Btu)
BLUE = 35+kW (120,000+Btu)
Please refer to pages 12 and 15 for fitting the regulator instructions.
Balanced high pressure system
The cold water supply must be drawn from the same mains supply as that to the hot water system (down stream of
the cylinder manufacturer’s pressure limiting valve, where supplied) and the hot supply from the nearest convenient
draw off point. Account must be taken of pressure drops that may occur when other draw off points are used while
the shower is in use.
