Important information
Introduction
The Aquavalve 700 Thermo is a brass bodied thermostatic shower valve designed for built in and concealed panel mount and
exposed installations. The Aquavalve 700 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.
If you have any questions at any stage during installation please contact the Aqualisa customer helpline on 01959 560010
for advice.
Commercial applications
This product is suitable for commercial applications. Products BBV001 (exposed) and BBV002 (concealed) should be ordered.
The BBV001 is fitted with the ⁄÷™” outlet at the top of the valve to facilitate the use of an exposed fixed head, rather than at
the bottom of the valve as per the domestic 700.51.01 version.
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 current Water Supply Regulations prior to
connection of the product.
Connections
The Aquavalve 700 Thermo is supplied for connection to conventional supplies with HOT on the LEFT and COLD on the RIGHT
when viewed from the front. However, for non-conventional supplies, the valve can be reversed by 180º. Please see installation
instructions overleaf to reverse the valve.
The Aquavalve 700 Thermo exposed valve is supplied complete with 15mm compression elbow fittings at 198mm centres. The
Aquavalve 700 Thermo concealed valve is not supplied with any elbow connections. Suitable ‹÷¢” BSP union connections will
need to be used.
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 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
or 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 height shower head). 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.

Aqualvalve 700 Thermo installation instuctions page 5
Important information
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 typical layout is shown on the reverse of this guide.
Stored water capacities
The minimum capacity of the cold storage cistern should not be less than 225 litres (50 gallons). The capacity of the hot
cylinder must be capable of meeting the anticipated demand.
Pressures
The Aquavalve 700 Thermo shower 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.
The Aquavalve 700 Thermo is not suitable for mixed supply systems e.g. gravity hot and mains cold.
A suitable PRV is available from Aqualisa.
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 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 TEMPERATURE IN EXCESS OF 65ºC 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.
A typical layout is shown on page 14 of this guide.
Balanced high-pressure system
The Aqualisa 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 supply
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 page 14 of this guide.
Combination boiler/multipoint system
The gas water heater must be capable of raising the temperature of the incoming water by 35ºC 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 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 page 14 of this guide.
