Electrical Installation

WARNING!

EARTHING :

• A) The Earthing installation should be carried out in accordance with the local Wiring Regulations.
• B) The Electric Water Heater must be earthed. Improper grounding, such as Earth conductor not grounded (floating) or having high resistance to ground, could cause malfunction to ELCB (Earth Leakage Circuit Breaker) and electrical shock. Never use water heater if there is doubt on Earthing installation.
• Always SWITCH OFF the mains electric power supply before carrying out any electrical work.
• Use double insulation cable and choose correct cable size as TABLE 1 for electrical installation.
• Refer to SAFETY INFORMATION before Plumbing and Electrical Installation for safety and warning details.

1. Lead the power cable from MCB to an “ON/OFF’’ double-pole switch having a contact separation of at least 3mm in all poles outside the bathroom, then lead a cable to the terminal block inside the Electric Water Heater Unit.

NOTE: Refer to TABLE 1 for electrical loading and correct size of wire conductor

2. Insert the wall embedded cable through Side Entry ‘A’ by cutting a hole at the source cord rubber holder and lead the cable to Cable Bracket ‘B’.

3. Connect the mains cable to the Terminal Block as follows:

4. Reconnect the temperature display cable from front cover to the Main Control PCB. Clamp the cable to the correct position.
   

5. Double-check if the wiring connection is correct.
   For first installation, it is advised to check for earth connection of the water heater.
   Earth light will light up if wire connection is properly done. If the earth light does not light up, installer needs to check the following.
   a. Ensure Live and Neutral wire are fixed in correct position
   b. Ensure Earth wire connection is properly fixed
   If earth light still does not light up, please contact electrician to check household earth connection.

6. Install the temperature knob to the front cover.
   Note: The temperature knob is packed inside the accessory box.

7. Position the temperature knob and the control rod as shown below and reinstall the front cover.

8. Reinstall screw A.

USAGE INSTRUCTION

Each time the power supply is switched on, the unit will run a self-check. The 3 LED Indicators “Earth,” ”Power/Heater,” and “ELCB” will light up white one by one to indicate the unit is self-checking. After self-checking, the 3 LED indicators will remain white. Display will show “on” as no problem.
If there is any issue, the LED indicators will behave as shown below:

If any issue occurs, turn off the mains supply and turn it on again. If the issue persists, contact local Electrolux Service or authorized service technicians.

Temperature Control
Turn on the Temperature control knob to ‘ON’, the 3 LED indicators “Earth,” “Power/Heater,” and “ELCB” will light up amber, and the outlet water will become warmer within a few seconds.
The more Temperature Control Knob being turned clockwise, the hotter the water becomes.

• If the water is overheated or the water flow stops, the 3 LED indicators will light up in white.
• The temperature display will show the set temperature within a range of 32°C to 45°C.
• The Electric Water Heater might not be hot enough even at the ‘MAX’ position if the incoming water supply is too cold or the flow rate of water is too high. In this case, you may adjust the 3 in 1 Stop Valve to reduce the water flow rate to get the desired showering temperature. (Recommended flow rate should be below 6 liter/min)
• If the water flow rate is too low, the heater cannot be activated.
• It is unnecessary to turn the Temperature Control Knob to “OFF” position when the Instant Hot Shower is not in use.
• Switch OFF the power supply after the shower.

Cold Shower
Turn the Temperature Control Knob to ‘Off,’ the 3 LED Indicators “Earth,” ”Power/Heater,” and “ELCB” will light up white. Heater will be off.

Check the Built-in ELCB

1. Press the “TEST” Button, the Built-in ELCB (Earth Leakage Circuit Breaker) should trip and cut off the power supply. The “Earth” and
   “Power/Heater” indicator should turn off. ELCB indicator will blink with amber. Meanwhile, the display will show “E1”.

2. Press “Reset” button, the unit will run a self-check (refer to Self Check section in page 11)
   If there is any issue, the LED indicators will behave as shown in the self- check section.
   Pump feature (For model with pump feature only)
   Basic Pump Function
   Turn on the Pump Control Knob to increase the water flow rate when necessary. You may adjust the pump speed until the desired water flow rate and shower temperature is obtained.
   Booster Pump Function
   If the power supply is ON, and the water flow rate is not sufficient to activate the flow sensor, the Booster Pump Function can be useful to help increase the incoming water flow rate. Turn the pump knob to OFF position, then turn to Max position, the Booster Pump Function will be actived to increase the incoming water flow rate. If the increased water flow can be maintained above the flow sensor activation level, the Electric Water Heater will resume working continuously as normal. If the increased water flow cannot be maintained above the flow sensor activation level, the Booster Pump Function will be auto OFF, and the Electric Water Heater will not be able to function normally due to the incoming flow rate being too low. (If the water flow is too low, the pump feature cannot be activated after the Booster Pump Function. It is advisable to avoid applying the Booster Pump Function to increase the water flow rate more than 3 times of each showering).

MAINTENANCE

Read the section “SAFETY INFORMATION” first.

1. TEST THE ‘ELCB (Earth Leakage Circuit Breaker)’ REGULARLY.
   This procedure is highly recommended to test at least once a month. Refer to the “Check the Built-in ELCB” for the testing procedure.

2. CLEAN THE FILTER REGULARLY
   Turn off the water supply before removing the filter.
   Clean the Mesh Filter regularly to prevent blockage. Remove the Built-in Filter by turning its cap anticlockwise. Whenever needed, flush the internal strainer with water to remove any trapped sediments. Whenever fixing back the Built-In Filter, beware of the alignment of Internal Strainer. Use the protruded guideline within Stop Valve to position the Internal Strainer.

Clean the Hand shower Head holes using the soft brush from time to time. (Recommended once a week)
Note: Take care not to damage the holes of the Hand shower Head during cleaning.
WARNING!
If the Power/Heater Indicator does not turn off when you press the ELCB (Earth Leakage Circuit Breaker) Test Button, switch OFF the mains supply and contact Electrolux Consumer Care Centre for repair service. Special skill is required for repairing. NEVER try to repair the unit by yourself.

CLEANING PRECAUTION!
Do not use thinner, alcohol, petrol, or any other organic solutions to clean the set. Use only a damped cloth with mild detergent.
Do not spray on the unit.
