Important information
Introdu tion
The Aquatique Thermo is an antique style brass bodied thermostatic shower valve designed for built in and concealed panel
mount and exposed installations.
The Aquatique Thermo provides close temperature stability and fail safe protection when installed on approved gravity or
pumped systems and balanced high pressure systems. A cold inlet flow regulator is provided for use with instantaneous
(multipoint) gas water heater and combination boiler applications.
Flexible and 5” and 8” drencher heads are available to complement the Aquatique Thermo valves, dependent on your water
system, and should be purchased separately.
If you have any questions at any stage during installation please contact the Aqualisa customer helpline on 01959 560010 for advice.
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply Regulations.
Flushing
Some modern fluxes can be extremely corrosive and, if left in contact, will attack the working parts of this unit. All soldering
must be completed and the pipe work thoroughly flushed out in accordance with Water Supply Regulations prior to connection
of the product.
Conne tions
The Aquatique Thermo is supplied for connection to conventional supplies with HOT on the LEFT and COLD on the RIGHT
when viewed from the front. However, the valve can be adapted for use with non-conventional supplies by rotating the valve
body by 180˚. Please see installation instructions overleaf to reverse the valve.
The Aquatique Thermo exposed valve is supplied complete with 15mm compression elbow fittings at 198mm centres. The
Aquatique Thermo concealed valve is NOT supplied with any elbow connections. Suitable ‹÷¢” BSP union connections will be required.
Pipe work connections to this product should be cut using a rotary type cutter.
Isolating valves
Suitable isolation valves such as gate valves must be fitted to both supplies in accordance with the 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 or gravity pumped installations.
Filters
To ensure ongoing optimum performance the internal control mechanism ‘cartridge’
is protected by a two-part filter system. 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
cartridge be removed and the filters checked by a competent person. In the event of
any difficulties please contact the Aqualisa customer helpline for assistance.
Siting
For optimum performance, with gravity fed systems the distance between the bottom of the storage cistern and the shower
head should not be less than 1m (when using an adjustable shower kit). If using a fixed head, the highest point of the pipe
work must be not less than 1m below the underside of the cistern. Please refer to the system layouts on the reverse of this guide.
Pump installation
UNDER NO CIRCU STANCES UST A PU P BE FITTED DIRECTLY TO THE WATER AIN
A pump must only be used to boost the pressure from tank-fed supplies. A typical
layout is shown on the reverse of this guide.

Important information
Stored water apa ities
The minimum capacity of the cold storage cistern should be less than 225 litres (50 gallons). The capacity of the hot cylinder
must be capable of meeting the anticipated demand.
Pressures
The Aquatique Thermo valve is designed to control static pressure up to 10 bar. Where pressures are likely to exceed 10 bar a
pressure reducing valve (PRV) must be fitted into the incoming mains supply. A setting of 3 bar is recommended. It should
be noted that daytime pressures approaching 8 bar can rise above the stated maximum overnight.
A suitable PRV is available from Aqualisa.
Gravity fed hot and old 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.
CYLINDER TE PERATURE IN EXCESS OF 65˚C AY RESULT IN POOR SHOWER PERFOR ANCE
To minimise pressure loss we recommend that the hot and cold supplies are run in 22mm as close as is reasonably possible to
the mixing valve before reducing to 15mm.
Balan ed high-pressure system
The Aquatique Thermo cartridge is designed to operate with unvented hot water storage systems up to a maximum pressure
of 10 bar. A PRV must be used if either supply exceeds 10 bar. The cold water supply must be drawn from the same mains sup-
ply as that to the hot water system (down stream of the cylinder manufacturers 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. Pipe work can generally be run in 15mm.
A typical layout is shown on the reverse of this guide.
Combination boiler/multipoint system
The gas water heater must be capable of raising the temperature of the incoming water by 35˚C and delivering a flow rate of
no less than 9 litres (2 gallons) per minute to the shower valve. This is sufficient to operate one outlet point at a time.
The Aqualisa Thermo cartridge is designed to operate from the mains at a maximum pressure of 10 bar. If the mains pressure
exceeds 10 bar a ‘drop tight’ PRV must be fitted on the supply pipe after the main stopcock.
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. Pipe work can generally be run in 15mm.
A typical layout is shown on the reverse of this guide.
Complementary shower heads
Various shower heads are available to complement the Aquatique Thermo unit, which are available separately. Please select
from the following options:
Option 1. Adjustable height kit. Choose from adjustable height kit concealed or exposed (compatible with any water system).
Option 2. 5” drencher head. Choose from exposed or concealed (compatible with most water systems – the flow switch on
combination boilers should be capable of passing a minimum of 12 litres per minute at 55ºC. If in any doubt, please contact
the appliance manufacturer before installation commences.
Option 3. 8” drencher head. Choose from exposed or concealed (compatible with high pressure or boosted systems only).
Please refer to the installation guides supplied with the shower heads for full fitting instructions.

Reversed supplies
The Aquatique Thermo is designed for conventional supplies with HOT on the Left and COLD on the Right as viewed from the
front. However, the Aquatique Thermo can be adapted for use with reversed supplies, adopting the following procedure.
1 Set the temperature lever to the vertical position and remove the temperature screws and temperature lever/on/off assembly.
2 Remove the elbow connections and loosen the locking screw in the bottom of the valve base plate. Rotate the valve body
180˚ and tighten the locking screw in the valve base plate.
3 Unscrew and remove outlet connector using a 12mm hexagonal key or radiator key and remove the outlet plug using a snug
fitting screwdriver taking care to avoid any damage to the plated surfaces.
4 Reposition and refit the outlet and outlet plug as required.
5 Refit the elbow connections.

Replace the temperature lever/on/off assembly ensuring the temperature lever is in the vertical position. Secure the assembly to
the valve body with the four screws, hand tight only.
Temperature Limiting Devi e
For additional safety, for example when the very young or elderly people will be using the shower, the Aquatique Thermo incor-
porates a temperature limiting device enabling you to set minimum and maximum temperature adjustment if required.
Temperature adjustment is limited by inserting the limiting pins provided into the small holes in the face of the cartridge.
The pins are fitted as follows:
1 Ensure the temperature lever is set to the vertical position.
2 Remove the four temperature control lever fixing screws and detach the lever and on/off control.
3 Replace two of the screws in the top and bottom threaded holes of the temperature ring.
4 To set the AXI U temperature, insert a limit pin into the mid-position hole in the upper set of holes.
5 Using the two screws in the cartridge face as a lever, turn the temperature control ring clockwise until a stop is reached.
6 Temporarily replace the on/off control and temperature control lever and turn the valve on to check the temperature is at the
desired maximum temperature. If not, turn the valve off, re-position the pin in a higher hole and turn on the valve to
check the temperature is sufficient. Repeat the procedure as necessary.
7 If a minimum temperature is required, use the lower set of holes in the cartridge face and repeat the above procedure. If no
minimum temperature is required, do not position any pins in the lower set of holes
8 Snap off the pins by levering outwards. Turn the temperature control ring to the vertical position and remove the two fixings
screws. Replace the temperature control lever and on/off control assembly in its original position and fix with the four tempera-
ture screws, hand tight only.
