Operation
1.
Turn on the water isolation valve.
2.
Turn on the electricity supply.
3.
Check the Control Hub for power. (The LEDs inside the Hub should be illuminated).
4.
The Kelda Showers system operates by detecting water flow. It starts when water flow is detected and stops when
the water flow ceases.
5.
Open the shower mixer/valve. Water should start to flow from the shower head, followed very quickly by the air flow.
Once the water valve times out, the water will cease to flow and the air will continue to operate briefly. 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!
Troubleshooting
Symptom
Likely cause
Action/Remedy
System does not operate fully
(reduced or no water flow):
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 difference between hot and
cold supplies is too high
Adjust screws on mixer to balance. Or fit
pressure reducer on high pressure supply.
Shower mixer/valve not functioning.
Check valve, replace if necessary.
Water flows 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 off
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 flow sensor is not
jammed or faulty.
Temperature fluctuating:
Thermostatic control/Boiler issue.
Check thermostatic mixer valve/boiler for
an issue, call a specialist if necessary.
Poor/no water flow:
Blocked water filter/strainer.
Isolate water supply and service strainers
in mixer or group mixer.
Water flow too strong:
Flow restrictor not installed.
Check if the flow restrictor is properly
installed (in the back of the head).
