Installation of Digital pumped pro essor (for gravity stored systems)
The HiQu 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 pro essor (for balan ed high pressure and
unvented systems, ombination boiler systems and separately pumped gravity
systems)
Pressures: The HiQu 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.
Spe ial notes for ombination 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.

Conne tions
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-off length by more than
2mm.
THESE FITTINGS ARE NOT SUITAB E FOR STAIN ESS STEE TUBE.

HiQu Digital Concealed installation instructions Page 6
Pipe sizing
ong pipe runs, on both inlet and outlet, will reduce the flow rate at the shower head. 22mm pipe work should be
used on the 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 then copper pipe is preferred, and 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 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.
After installation
Familiarise the end user with the HiQu Digital operation and hand them this guide. Complete and post the
guarantee card or register online at www.aqualisa.co.uk

!
Isolation valves are supplied with the Digital
processor and must be fitted on both inlets
and the blended water outlet. All pipe work
should be run in 15mm pipe. All pipe work
should be supported. For externally pumped
gravity fed installations, 22mm pipe work
should be run as close to the processor as
possible before reducing down to 15mm.
2
The inlet supply centres are 48mm. The inlet supply centres deviate from
EN1111 and EN1287, but are deemed to be a special case.
Please note arrow on isolation valve to indicate direction of flow.
Compression fittings should not be used on the inlet and outlet spigots and
may affect the warranty if fitted.

The Digital processors are supplied factory set
with the flow rate at either ‘NORMA HP’ or
‘NORMA GRAVITY’ mode depending on
which shower system has been ordered.
STANDARD PROCESSORS ON BA ANCED HP
SYSTEMS:
Standard processors fitted to balanced high
pressure systems may be set to ‘NORMA HP’
or for water economy ‘ECO’ modes.
N.B. As ‘ECO’ flow can be achieved by the HiQu Digital controller,
we recommend the processor is set to ‘NORMA HP’ mode.
STANDARD PROCESSORS ON COMBINATION BOI ER SYSTEMS:
For Standard Digital processors installed on combi boiler systems, for optimum
performance we recommend setting the flow rate to the ‘COMBI’ mode.
18
N.B. The ‘ECO’ flow rate mode should not be selected for shower systems
fitted to combination boilers.
PUMPED PROCESSORS:
Pumped processors fitted to gravity systems may be set to ‘NORMA GRAVITY’
or for water economy ‘ECO’ flow rate modes.
N.B. As ‘ECO’ flow can be achieved by the HiQu Digital controller,
