Quartz™ Bath Installation Guide 05
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.
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-
o 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.
Flushing
Some modern fluxes can be very 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 local and national Water Supply
Regulations prior to connection of the product.
Declaration of conformity
