The Kelda shower system is a ground breaking, patented technology that injects water into an air stream to deliver a unique “real rain” effect showering experience. This provides a shower force equivalent to twice that of a conventional shower, thereby offering water savings of over 50%* and associated water heating energy savings.

The Kelda shower system is designed to be used in conjunction with virtually any pre installed water valve. General arrangement — refer to diagram on page 5. The Shower head (1) is installed within the shower area against a service area wall. The Control Hub (2) is installed on the wall within the ceiling void area. A 150W-36V AC electrical supply (3) is required to be connected to the Control Hub via a 32mA RCBO device.

Water supply is plumbed to a shower control mixer/valve (not supplied). The outlet of this valve is then plumbed directly to the shower head attached to the compact. Air is supplied to the shower head from the air outlet connection of the Control Hub with the hose supplied.

Factory settings

Your Kelda shower’s flow rate is set via a flow regulator fitted within strainer and flow regulator assembly. This is shipped separately to the site specific showers depending on what flow rate is required and what water pressure your system is running at.

Water flow rate

Air volume

A i r o ve r ru n fu n c t i o n

The system has an air overrun function which allows the air to continue to operate for approximately 1-2 seconds after the water flow stops. This function purges the water from the shower head, reducing the build up of lime-scale.

The rate at which the air is delivered to the shower will automatically modulate as water flow changes to maintain optimum water/air ratio. However when commissioning the shower, the air flow rate has to be set to take into account site variations, or changed to suit the user’s requirements.

Changing the fan speed (10 settings)

• The factory setting is set at 7 • Press Speed DWN once, the number of LED flashes next to the button indicate what fan speed setting the Control

Hub is currently set at. (There are 10 speed settings: 1-10)

Symptom Likely cause Action/RemedySystem does not operate: Electricity supply (the standby power

LED is not illuminated).Check power supply is connected properly and electricity is turned on.

Fuse blown/RCBO tripped indicatingpossible electrical fault.

Check group fuse box/RCBO and replace if necessary, contact customer services if problem continues.

Water isolation valve. Turn on valve.

Shower mixer/valve not functioning. Check valve, replace if necessary.

Power is on but LED not illuminated:

Wire has disconnected from correct terminal/Fuse has tripped.

Open Control Hub’s front cover and check wire from PCB to cover is properly connected/ Check group RCBO.

Water flows from shower head but no shower spray:

Electricity supply (the standby power LED is not illuminated).

Check power supply is connected properly and electricity is turned on.

Conduct “hard reset” by switching electricity off, wait 10 seconds, switch electricity on.

Air hose disconnected. Make sure air hose is connected properly refer to HOSE INSTALLATION for help.

Kink in air hose. Make sure air hose is unkinked with a steady bend (NO SHARP CORNERS).

Temperature fluctuating: Group 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. Disconnect water inlet hose, remove and clean filter, replace filter.

Water flow too strong: Flow regulator not installed. Check if the flow regulator is properly installed (In the shower head water inlet).

Operation1. 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 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.
