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
