Important information
Introduction
The Quartz Thermo is designed for both built-in and concealed panel mount installation and is supplied complete with
adjustable height head. Quartz 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.
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply Regulations.
Quartz Thermo is designed for domestic use only.
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 pro duct.
Connections
The Quartz Thermo valve incorporates ‘push fit’ type connections for use with 15mm British Standard copper tube. Tube
should be cut using a rotary type cutter and lubricated using a silicone based lubricant or petroleum jelly (Vaseline or similar)
prior to insertion into the fitting. Supply lines must be flushed clear of any debris before installation of the unit.
If plastic pipe is to be used, the tube insert must not increase the tube diameter or extend the cut off length by more than 2mm.
THESE FITTINGS ARE NOT SUITABLE FOR STAINLESS STEEL TUBE
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 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 page 15

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 Quartz 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.
Quartz 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 oon page 15.
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 oon page 15.
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 oon page 15.
