Important information
Safety information
This product must be installed by a competent person in accordance with all relevant current Water Supply Regulations.
ALL SHOWERS REQUIRING AN ELECTRICAL CONNECTI0N MUST BE INSTALLED BY A QUALIFIED PERSON FOLLOWING THE
LATEST REVISION OF BS 7671 (WIRING REGULATIONS) AND CERTIFIED TO CURRENT BUILDING REGULATIONS.
This system should be installed so that other taps or appliances operated elsewhere within the premises do not significantly
affect the flow.
The shower must not be used with a hot water supply temperature of over 65ºC.
We recommend the MAXIMUM outlet temperature is set to 46ºC (factory pre-set at max 45 ºC).
The Digital processor must be installed in an accessible location for servicing and maintenance.
The Digital processor must not be installed in situations where the ambient temperature is likely to exceed 40ºC.
The control must not be installed in situations where the ambient temperature is likely to fall below 5ºC or rise above 70ºC.
We do not recommend the use of Quartz Digital in steam therapy facilities.
This appliance must be earthed.
Cables which are chased into the wall must be protected by a suitable conduit or sheathing.
Surface mounted cables must also be protected by a suitable approved conduit.
Please note that special protection of the data cable may be required in vermin infested areas.
The power lead must only be replaced by the manufacturer or his accredited agent.
The user control is supplied from a safety low voltage source.
This product is suitable for domestic use only.
Quartz Digital is supplied complete with a 5 year guarantee.
Installation of Digital pumped processor (for gravity stored systems)
The Quartz Digital pumped shower system is designed to operate up to maximum static pressure of 100kPa
((1 bar)(10 metres head)(14.5psi)).
Under no circumstances must the pumped processor be connected directly to the water main or in line with another booster pump.
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 anticipated demand.
Installation of Digital standard processor (for balanced high pressure and unvented
systems, combination boiler systems and separately pumped gravity systems)
Pressures: The Quartz Digital standard shower system 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 (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, THE SHOWER FLOW RATE MAY VARY
WITH CHANGES TO THE MAIN INLET TEMPERATURE. INLET TEMPERATURE CHANGE MAY ALSO CAUSE THE DIGITAL
CONTROLLER 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.
