Water Heater
They instantly heat water as it flows through the unit. It will keep heating the water flowing though it indefinitely, on demand. Hot water when you want it.
Warranty period of the product will be active from the day the product has been purchased.
Please check that the electrical supply to the heater is switched on. Check that the green light on the water heater is lighted up. Instant water heater: Turn on the stop valve and the red light will light up with water flowing out from the shower head. Storage water heater: Check that the storage water heater has a red light turned. If you still do not have hot water, call us at our hotline.
It will normally take 4-5 working days after receiving product in our place.
When the water pressure supplied to water heater is too high, especially for water storage heaters, it can cause the pressure relief valve to release the high pressure through the overflow pipe. Please call the building management personnel to find the cause of this high pressure. High water pressure can cause unnecessary water leakage.
It is advisable for clients to arrange a service meeting with our technicians because a doorstep service allows our technician to rectify problems such as water supply or electric supply problem
The problem of water pressure arises from household water supply. The water heater only heats up the water from the existing water pressure supplied to the heater.
1. Insufficient water flow, incoming water flow too low, which just able to activate the flow switch.
Dirt particles blocking hand shower spray, or dirt particles blocking filter at inlet stop valve. See 1.1 & 1.2 remedy.
2. Increase of incoming water temperature, where water cistern on roof top and it is exposed under the sun.
Turn the temperature control knob to minimum or off and increase water flow rate by
– turn the stop valve’s regulator to a maximum flow.
– turn pump speed control to maximum speed.
Warranty card and proof of purchase must be available for any warranty claims.
It could be possible that your wiring problem such as MCB under size. Please check and rectify it with your wireman and if it still trips after being checked, that means there is something wrong with thermostat & heating element.
The term Dryburn is used to explain the problem of storage water heater electrical being switched on before water is filled within the tank causing the heating element or thermofius to burn. The copper heating element is to heat up the water like any element in the kettle. It’s important to ensure that the tank is full of water to ensure heating element is always immersed in the water to avoid it from dryburn. Upon experiencing water shortage, please switch off your electrical supply to your storage water heater.
Problems in installation normally arise from wrong installation or wiring problems. Please read the instruction manual carefully before performing any installation. Inlets and outlets must be on the correct side and ensure that water supply is on and there is proper electrical supply to the heater before turning on the water heater.
1. Dirt particles blocking filter at inlet stop valve.
Remove filter at inlet stop valve and clean.
2. Dirt particles blocking hand shower spray.
Rub hand shower rubber nozzle to remove dirt particles. *this procedure must be made with water spraying out from hand shower.
3. Interrupted Water Supply.
Check whether the water supply is available, by taking out inlet stop valve connection and check if water supply is available.
4. Incoming water supply stop valve, service valve turned off.
Turn on stop valve & service valve.
5. Low water supply
Heater require minimum 2 liter per minute or 3 psi to activate flow switch.
6. Malfunctioning on Flow Switch (magnet jammed or reed switch failed).
Magnet jammed / dislocated. Replace with new part.
Reed Switch Failure. Replace with new part.
1.Interrupted of Power Supply.
Check if unit’s Built in ELCB trip, Mains Distribution Panel On/Off Switch turn off, Mains Distribution Panel’s ELCB Trip, or MCB Overloaded. Check other appliances sharing the same ground network has current leakage, which causing ELCB Trip.
2. Thermal Cut- Out 85 º C manual reset has operated.
Reset by pressing button of thermostat. Check root cause of thermal cut-out operated. 4 possibility: Magnet jammed, Reed Switch failure, EC Control board failure, Triac shorted. Replace the components one by one to troubleshoot.
3. Unit’s built in ELCB trips.
1. Check if current leakage is happening, where heating element burnt, L&E or N&E is connected, or L&N open circuit, replace if -necessary.
2. Check if the ELCB is struck by lightning (varistor blown), replace if necessary.
3. Check if the ELCB’s fuse is connected, replace if necessary.
1.Earth wire in bad connection.
Check earth wire connection (by appointing a qualified electrician)
2. Other appliances sharing same earth network having current leakage.
Check other home appliances, whether current leakage has occur to other appliances in the house, which sharing the same earth network.
1. Heating element current leakage.
Replace heater tank.
2. Wrong wiring during installation or wiring faulty, Live wire touching Earth wire, or Neutral wire touching Earth wire.
Ensure wiring connection is correct and check for faulty wiring.
