Surface mounted cables must also be protected by a suitable approved conduit, even in a loft, where there may
be a risk of damage from vermin.
The power lead must only be replaced by the manufacturer or his accredited agent.

This product is suitable for domestic use only.
Quartz Digital is supplied with a 5 year guarantee.
Installation of Digital Gravity Pumped processor (for gravity stored
systems)
The Quartz Digital Gravity Pumped shower system is designed to operate up to a 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 HP/Combi processor (for balanced high pressure
and unvented systems, combination boiler systems and separately
pumped gravity systems)
Pressures: The Quartz Digital HP/Combi 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, SEASONAL INLET
TEMPERATURE CHANGE WILL AFFECT THE PROCESSOR OUTLET FLOW RATE RESULTING IN VARYING SHOWER
FLOW RATE AND FLOW CONTROL RANGE. INLET TEMPERATURE CHANGE MAY ALSO CAUSE THE TEMPERATURE
LED’S TO FLASH; THIS IS NOT NECESSARILY CHANGING THE OUTLET TEMPERATURE.
