Safety information
This product must be installed by a competent person in accordance with all
relevant current Water Supply Regulations. ALL PRODUCTS REQUIRING AN
ELECTRICAL CONNECTI0N MUST BE INSTALLED BY A QUALIFIED PERSON FOLLOWING THE
LATEST REVISION OF BS 7671 (WIRING REGULATIONS) AND CERTIFIED TO CURRENT
BUILDING REGULATIONS.
This system should be installed so that other taps or appliances operated elsewhere within the premises do not significantly affect the flow. The Digital Shower 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 DIGITAL PROCESSOR MUST BE INSTALLED IN AN ACCESSIBLE LOCATION 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.
Installation of Digital pumped processor (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 processor (for balanced high pressure and
unvented systems, combination 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.
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 RATES. INLET TEMPERATURE CHANGE MAY ALSO CAUSE THE TEMPERATURE LED’S TO FLASH; THIS IS NOT NECESSARILY CHANGING THE OUTLET 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 SUITABLE FOR USE WITH A SINGLE 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 FLOW RATES WE RECOMMEND USING COPPER PIPE WITH THE MINIMUM AMOUNT
OF ELBOWS. THESE FITTINGS ARE NOT SUITABLE FOR STAINLESS STEEL TUBE.
Pipe sizing
Long 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 especially if a diverter is installed.
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
