Insta ation of Digita pumped processor (for gravity stored systems)
The HiQu Digital pumped bath 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.

HiQu Digital Bath installation instructions Page 5
Insta ation of Digita standard processor (for ba anced high pressure and
unvented systems, combination boi er systems and separate y pumped
gravity systems)
Pressures: The HiQu Digital standard bath 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.
Specia notes for combination boi er 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.
P EASE NOTE: DUE TO PERFORMANCE CHARACTERISTICS OF COMBINATION BOI ERS, SEASONA IN ET TEMPERATURE
CHANGE WI AFFECT THE PROCESSOR OUT ET F OW RATE RESU TING IN VARYING BATH F OW RATE. THIS WI AFFECT
PRE-SET DEPTH EVE S. IN ET TEMPERATURE CHANGE MAY A SO CAUSE THE TEMPERATURE ED’S TO F ASH; THIS IS NOT
NECESSARI Y CHANGING THE OUT ET TEMPERATURE.
Specia notes for separate y 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 SUITAB E FOR USE WITH A SING E ENDED PUMP.
Connections
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.
TO MAXIMISE F OW RATES WE RECOMMEND USING COPPER PIPE WITH THE MINIMUM AMOUNT OF E BOWS. THESE
FITTINGS ARE NOT SUITAB E FOR STAIN ESS STEE TUBE.
Pipe sizing
ong pipe runs, on both inlet and outlet, will reduce the flow rate at the shower head. If long pipe runs are
unavoidable, use copper pipe rather than plastic. If plastic pipe is used, minimise the number of elbows as the pipe
inserts are very restrictive, consideration should be given to using 22mm plastic or copper pipe.
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.

ital 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 exter-
nally pumped gravity fed installa-
tions, 22mm pipe work should be run
as close to the processor as possible before re-
ducing down to 15mm.
