Frequently Asked Questions - EWH-E3883AC(SG) Elba

What is the power consumption of the Elba EWH-E3883AC(SG) water heater?

The rated power is 3.6 kW at 240 V. However, the heater supports multiple power settings (3.5 kW to 8.8 kW depending on voltage and model variant). Refer to the electrical loading table in the manual for details.

Can I install this water heater myself?

No, installation must be carried out by a qualified electrician in compliance with local regulations. Improper installation may cause electric shock or fire hazard.

How do I test the ELCB (Earth Leakage Circuit Breaker)?

Press the 'TEST' button on the unit. The POWER and HEATER LEDs should turn off, indicating the ELCB has tripped. Then press 'RESET' to resume normal operation. Perform this test monthly.

What should I do if the water temperature is too low?

Ensure the temperature control knob is turned clockwise to a higher setting. Also check that the water flow rate is not too high; reduce flow using the pump control knob (if applicable) or partially close the stop valve. Minimum flow required is 2 L/min.

Can I use a metallic flexible hose with this heater?

No, do not use metallic or chromed flexible hoses or conductive control valves. Only use non-conductive hoses recommended by the manufacturer to avoid electric shock.

How do I clean the inlet filter?

Turn off the water supply, then remove the filter knob at the stop valve (if equipped) by turning counterclockwise. Flush the filter mesh with water to remove sediments, then reinstall.

What does the 'HEATER' LED indicate?

The HEATER LED lights up when the heating element is active. If the LED is off but water is not heating, check the temperature control knob setting and ensure water flow is sufficient to trigger the flow switch.

Is the water heater suitable for use with a rain shower?

Yes, the heater comes with an optional rain shower set (FiOtto Series). It includes a 360-degree 3-in-1 rotation diverter and water saver chips. Ensure proper installation to avoid leakage.

What should I do if the ELCB keeps tripping?

Frequent tripping may indicate a current leak. Immediately stop using the heater and consult a qualified technician. Do not attempt to repair it yourself.

Can I use the heater without the pump?

The EWH-E3883AC(SG) is a pump model. If you prefer a non-pump version, consider the Elba EWH-E3881. The pump boosts water flow; it can be turned off via the pump control knob if desired.

A chip that helps you save water up tp 50%!

ALERT

You may remove the two water saver chips if prefer stronger water pressure. Please be reminded that this is up to personal preference.

STEP 2

Do marking for the location of the lower square and upper round bracket. Install the bracket holders on the wall.

Assemble the upper tube with rain shower and lower tube with divider.

Slide down and hook the assembled divider to the mounted square bracket.

Tighten the screws and make sure all joints are completely connected to avoid leakage.

2. GENERAL INFORMATION

INSTALLATION

CAUTION: THIS APPLIANCE MUST BE EARTHED.

1. All the plumbing work should be completed before proceeding to electrical wiring connection. (Table 1)
2. Installation must be carried out by a qualified electrician with close reference to the operation manual and in compliance with the local regulations.
3. The unit works at minimum water flow rate of 2 litre/min, which then would trigger the built-in pump (only for pump model), boosting a stronger shower spray.
4. The built-in electronic Earth Leakage Circuit Breaker (ELCB) would cut-off the power supply to the heater in the event of current leakage of as low as 15mA. (Refer to AUTO INSPECT ALARM Indication - optional)
5. The Thermal Cut-Off would automatically shut off the power supply shall there is any abnormal rise of showering temperature.
6. The unit only operates when there is sufficient water flow to trigger the flow switch.

3. INSTALLATION PROCEDURES

1. All the plumbing works should be completed before proceeding to electrical wiring connection.
2. INLET and OUTLET connection of the heater unit should not be reversed, with stop valve installed on INLET. (Diagram 1)
3. It is recommended that the unit should be mounted above 1.5m or 5-feet above the floor to bottom of the heater. (Diagram 1)

4. Mark mounting position (Diagram 2)

5. Remove screw at the bottom of the heater
   • Lift the plastic cover upward
   • Mark mounting position on the wall
   • Drill the holes with 5.0mm diameter drill bit
   • Install the unit to the wall with plug

6. Heater INLET and OUTLET Connection (Diagram 3)

a) Connect the stop valve to INLET, and be sure to put a gasket to prevent water leakage,
b) Connect the piping from the stop valve to incoming water supply. If necessary, make use of sealing tape for the connection to prevent water leakage.
c) Connect flexible hose to heater OUTLET. Turn on the water mains to drain out all the plumbing dirt and fill up the heater tank. Then, connect the flexible hose to the hand shower.

(Note: This step will prevent damage to the heating element).
