Installation Guide 03
Installation of the standard (unpumped)
Quartz Smart Valve
™
(for balanced
high pressure and unvented systems,
combination boiler systems and
separately pumped gravity systems)
Pressures: The standard (unpumped) Quartz
Smart Valve
™
is designed to operate up to a
maximum static pressure of 700kPa ((7 bar)
(100psi)). Where pressures are likely to exceed
700kPa ((7 bar)(100psi)), a pressure reducing
valve must be fitted to the incoming mains
supply. A setting of 400kPa ((4 bar)(60psi))
is recommended. It should be noted that
daytime pressures approaching 600kPa
((6 bar)(80psi)) can rise above the stated
maximum overnight.
Special notes for combination
boiler systems
The appliance must have a minimum domestic
hot water rating of 24kW 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 SMART
VALVE
™
OUTLET FLOW RATE RESULTING IN
VARYING SHOWER FLOW RATE AND FLOW
CONTROL RANGE. 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 and universal/negative
head pumps (for divert systems)
We recommend a
MINIMUM pump rating
of 1.5 bar. For optimum performance a 2.5 bar
pump should be used for all separately
pumped installations.
A twin ended pump is required for use with
single outlet products.
A universal/negative head type twin ended
pump (works on both positive and negative head
conditions) MUST be used with divert products.
The minimum actual capacity of the cold water
storage cistern should be not less than 225
litres (80 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.
Shower Heads
The range of shower heads has been designed
for use with Rise
™
systems.
Installation of any shower heads other than
these may result in poor shower performance.
If at any stage during installation you have any
questions then please contact the Aqualisa
Customer Service Department on 01959
560010 for advice.
Connections
This product incorporates 15mm ‘push-fit’
type connections. Tube should be cut using
a rotary type cutter and lubricated using a
silicone grease, petroleum jelly, or similar, prior
to insertion into the fitting. 15mm pipework
must be used to connect the product.
If plastic pipe is 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. COMPRESSION
FITTINGS MUST NOT BE USED.
Pipe sizing
PLEASE NOTE: Check pipe size requirements
for connections to outlets and accessories.
Long pipe runs, on both inlet and outlet, will
reduce the flow rate at the shower head, 22mm
pipe work should be used on inlets and reduce
down to 15mm as close to the valve as possible
to reduce pressure losses and help maintain
flow rate. If using 15mm pipe, copper pipe is
preferred, to optimise performance minimise
the number of elbows used. If long pipe runs
are unavoidable on the outlet, use copper pipe
rather than plastic, particularly if a diverter
is used, and minimise the number of elbows as
the pipe inserts are very restrictive.
