A PRODUCTS REQUIRING AN E ECTRICA CONNECTI0N MUST BE INSTA ED BY A QUA IFIED PERSON
FO OWING THE ATEST REVISION OF BS 7671 (WIRING REGU ATIONS) AND CERTIFIED TO CURRENT BUI DING
REGU ATIONS.
This system should be installed so that other taps or appliances operated elsewhere within the premises do not
significantly affect the flow.
The Digital Bath must not be used with a hot water supply temperature of over 65ºC.
The processor is supplied factory pre-set at maximum temperature of 45ºC. The maximum temperature is fully
adjustable to suit site conditions. If adjusted, we recommend the outlet temperature is set to a MAXIMUM of 46ºC.
THE DIGITA PROCESSOR MUST BE INSTA ED IN AN ACCESSIB E OCATION FOR SERVICING AND MAINTENANCE.
The Digital processor must not be installed in situations where either the ambient temperature is likely to exceed 40ºC
or where freezing may occur.
The control must not be installed in situations where the ambient temperature is likely to fall below 5ºC or rise above
40ºC.
We do not recommend the use of HiQu Digital in steam therapy facilities.
This appliance must be earthed.
Cables which are chased into the wall must be protected by a suitably sized conduit or sheathing to allow for
removal in the event of service and maintenance purposes. Ensure that the conduit is run to avoid the controller
fixing holes.
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.
The user control is supplied from a safety low voltage source.
This product is suitable for domestic use only.
HiQu Digital is supplied complete with a 5 year guarantee.
This product is not intended for use by persons (including children) with reduced physical, sensory or mental
capabilities or lack of experience and knowledge, unless they have been given initial supervision or instruction
concerning the use of the product by a person responsible for their safety.
Children should be supervised to ensure they do not play with the product.
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.

Isolation valves are supplied with the Dig-
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.
