Installation of Digital pumped processor (for gravity stored systems)
The ilux Digital pumped bath 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.

ilux Digital Bath with diverter installation instructions Page 5
Installation of Digital standard processor (for balanced ig pressure and
unvented systems, combination boiler systems and separately pumped
gravity systems)
Pressures: The ilux 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.
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.

TO F ASH; THIS IS NOT NECESSARI Y CHANGING THE OUT ET 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 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 bath outlet or 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.
After installation
Familiarise the end user with the ilux Digital operation and hand them this guide. Complete and post the guarantee
