Factory Settings
Air volume
Air overrun function
The system has an air overrun function which allows the air to continue to operate for approximately 1 second after the
water ow stops. This function purges the water from the shower head, reducing the build up of lime-scale.
Your Kelda shower will have a di󰀨erent fan speed setting depending on what shower head and water ow rate your prod-
uct has. This will be set at the factory.
The hub will automatically adjust fan speed to match minor changes in ow rate which may result from changes in
water pressure.
However the fan speed can be manually changed if for example the ow regulator is changed to a di󰀨erent value or for
other site specic reasons.
Changing the fan speed (10 settings)
• The fan settings are pre-set by the factory.
• To change the fan speed settings, press speed DWN once, the number of LED ashes next to the button indicate
what fan speed setting the Control Hub is currently set at. (There are 10 speed settings: 1-10)
1 . Speed down button
2 . Speed up button
Fan overheat protection
In the unlikely event of the fan overheating from being jammed with debris or being continuously run in a hot environment,
then a protection mode will be triggered with reduced fan speed and fast LED ash on Hub. The fan will return to normal
operation once debris is cleared or the temperature returns to operational level.
Fan Test Function
Press and hold both up and down fan speed buttons simultaneously to run the fan independently of full shower operation.
Time Delay Feature
• This is only if shower is being used with a digital push button or PIR control
• The factory setting is set at 30 seconds (3 LED Flashes)
• Press Timer DWN once, the number of LED ashes next to the button indicate what timer setting the Control Hub is
currently set at. (There are 5 timer settings: 10s,15s,30s,45s,60s)

Troubleshooting
Operation
1 . Turn on the water isolation valve.
2 . Turn on the electricity supply.
3. Check the Control Hub for power. (The Kelda Logo power indicator should be illuminated).
4 . The Kelda Technology system operates by detecting water ow. It starts when water ow is detected and stops when
the water ow ceases.
5. Open the shower mixer/valve. Water should start to ow from the shower head, followed very quickly by the air ow.
Once the water valve times out, the water will cease to ow and the air will continue to operate briey. This purges
water from the shower head.
Congratulations, you’re now ready to experience the greenest shower in the world and start saving water and
energy costs.
Symptom Likely cause Action/Remedy
System does not operate fully
(reduced or no water ow):
Hot or cold water supply isolation valve
closed
Check and open valve
Debris has caused blockage in mixer Isolate mixer and service strainers and
cartridge see mixer instructions to service
Pressure di󰀨erence between hot and
cold supplies is too high
Adjust screws on mixer to balance. Or t
pressure reducer on high pressure supply.
Shower mixer/valve not functioning. Check valve, replace if necessary.
Water ows from shower head
but no air:
Does the fan run? if so check seal of air hose connections
and that hose is kink free.
Is the LED on the front of the Control
Hub illuminated?
If no check electricity supply
Conduct hard reset by switching o󰀨
electrical supply and waiting 10 seconds
before turning on.
Debris in fan Clear any debris from fan and follow Fan
Test Function p.12.
If fan runs then check ow sensor is not
jammed or faulty.
Temperature uctuating: Thermostatic control/Boiler issue. Check thermostatic mixer valve/boiler for
an issue, call a specialist if necessary.
Poor/no water ow: Blocked water lter/strainer. Isolate water supply and service strainers
in mixer or group mixer.
Water ow too strong: Flow restrictor not installed. Check if the ow restrictor is properly
installed (in the back of the head).

Kelda Technology products are designed for easy maintenance and should give continued superior and safe
performance, provided:
1 . Kelda Technology products are installed, commissioned, operated and maintained in accordance with this installation
guide.
2 . Periodic attention is given as necessary to maintain the product in good functional order.
Guidelines for frequency are given below. Maintenance must be carried out in accordance with these instructions, and
must be conducted by designated, qualied and competent personnel. Kelda showers are built with the highest quality
components which are designed for a long life, but due care must be taken during maintenance to avoid damage.
Daily/Weekly hygiene
External surfaces of the chrome plated showerhead wiped clean with soft cloth and a mild detergent. Take care not to get
detergents on to stainless steel. Stainless steel should be regularly cleaned with warm water and soft cloth, taking care to
remove any dirt and remnants of shampoo or soap. See Stainless Steel Care for more details.
Quarterly hygiene*
Shower heads to be dismantled to clean, de-scale and sanitise main shower head components.
Please see instructions for dismantling and reassembling head for cleaning.
Unlike a conventional showerhead a Kelda showerhead is highly unlikely to block due to limescale and so service timings
can set purely for hygiene.
*This service point can be adjusted to suit site specic maintenance regime and shower usage levels.
Bi-annual visual & hygiene
Check internal component condition of the shower head and hoses. Inspect for debris, scale deposition, deformation,
damage, etc. Maintain or renew if necessary. Instructions for cleaning and disinfecting air hoses are given in this booklet.
Shut o󰀨 water supply, check stop valves then remove and clear lters of debris. These may be located in thermostatic
mixer if an one is tted.
If a mixer is tted into panel then please follow maintenance guide which is specic to that model of mixer.
Stainless Steel Care
Stainless steel requires regular cleaning for to keep its anti-corrosion properties, this can be done just with a soft cloth
and warm water. Glass cleaner can be used to remove ngerprints (we advise you spot test the use of any cleaner rst).
Chlorine, bleach, detergents, shampoos and soaps can all all strip stainless steel of its anti-corrosion properties and if left
uncleaned this can result in rust spotting. If you believe any of these substances have been in contact with the stainless
steel or if the panels need cleaning following a period of neglect, then use a stainless-steel cleaner – these are widely
available but stop test any cleaner rst.
If cleaning has been missed and rust spotting has occurred, then vigorous cleaning with stainless-steel cleaner can bring
back original anti-corrosion properties.
