Special notes for combination boiler systems
The appliance must have a minimum domestic hot water rating
of 24kW (80,000BTU) and be of the type fitted with a fully
modulating gas valve. If in any doubt, please contact the appliance
manufacturer before installation commences.
PLEASE NOTE: DUE TO PERFORMANCE CHARACTERISTICS
OF COMBINATION BOILERS, SEASONAL INLET TEMPERATURE
CHANGE WILL AFFECT THE QUARTZ
TM
SMART VALVE OUTLET
FLOW RATE RESULTING IN VARYING SHOWER FLOW RATES.
INLET TEMPERATURE CHANGE MAY ALSO CAUSE THE
TEMPERATURE DISPLAY TO FLASH; THIS IS NOT NECESSARILY
CHANGING THE OUTLET TEMPERATURE.
Special notes for separately pumped gravity systems
We recommend a twin ended pump with a MINIMUM pump rating
of 1.5 bar. For optimum performance a twin ended 2.5 bar pump
should be used.The minimum actual capacity of the cold water
storage cistern should be not less than 225 litres (50 gallons). The
capacity of the hot water cylinder must be capable of meeting the
anticipated demand.
THIS PRODUCT IS NOT SUITABLE FOR USE WITH A SINGLE
ENDED PUMP.
FOR DIVERT MODELS A UNIVERSAL TWIN ENDED PUMP
MUST BE USED.
Connections
This product incorporates ‘push fit’ type connections.
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.
If plastic pipe is used, the tube insert must not increase the tube
diameter or extend the cut-o length by more than 2mm.
TO MAXIMISE FLOW RATES WE RECOMMEND USING COPPER
PIPE WITH THE MINIMUM AMOUNT OF ELBOWS. THESE
FITTINGS ARE NOT SUITABLE FOR STAINLESS STEEL TUBE.
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 the pipe inserts are very restrictive. Consideration
should be given to using 22mm plastic or copper pipe especially if
a diverter is installed.
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.
Declaration of Conformity
Aqualisa Products Limited declares that the Q
TM
Controller, in
conjunction with the smart valve, complies with the essential
requirements and other relevant provisions of the Low Voltage
Directive (2014/35/EU), the EMC Directive (2014/30/EU) and
the RE Directive (2014/53/EU).
