FEATURES
2
1. Stepless Power Control
Provides user the ability to adjust the water temperature precisely based on their
own preferences.
2. Built-in Residual Current Device (RCD)
In the event of current leakage, Livinox’s highly sensitive built-in RCD will cut o both
live and neutral power supply
3. Inverter DC Booster Pump
In places where water pressure is inherently low, Livinox’s state of the art DC pump
can help boost water pressure with low noise operation and low energy consumption.
4. Double Thermal Anti-Scalding System
Our safety system cuts o power whenever the water temperature rises to 55°C
(Anti-scalding) and 90°C (Abnormal overheat).
5. IP25 Splash Proof
Livinox’s MB2 water heater comes with internationally recognised rating of IP25
protection. This means you can be rest assured that the internal electronics are always
protected against dust and water.
6. Smart Self-Check Safety Indication
Livinox MB2 water heater comes with an intelligent self-check safety feature that
informs the safety status of the heater before and during usage.
Self-checking function is indicated by power and RCD LED light running in sequence,
after which, one of the following three scenarios may occur:
a. Earth/RCD green light indicates that RCD is functioning normally and heater
safe to use.
b. Earth/RCD green light continuous blinking indicates that there is poor or no
earth connection. User is advised to contact professional technician.
c. Earth/RCD red light blinking indicates that current leakage is detected, and
RCD has tripped. User is advised to contact professional technician.
7. Water Temperature Heat Illuminator*
Water temperature indication is illuminated around the temperature knob area, with
orange light indicating minimum temperature and red light indicating
maximum temperature.
(*) This feature is applicable only for certain models which includes LWH-TS-E-MB, LWH-TS-DC-MB, LWH-TS-DC-RMB, LWH-TS-E-WH,
LWH-TS-DC-WH and LWH-TS-DC-RWH.

This Electric Instant Water Heater is a single point system and the“Water Outlet” can only
be fitted to the PVC Hose and Handshower set provided. NO CONTROL VALVE OR
FITTING CAN BE FITTED TO THE WATER OUTLET.
1. Connect the Stop Valve to the Water Inlet with washer. Use correct tools to tighten the
connection and be careful not to over tighten and damage the plastic nut.
2. Connect the incoming water piping to the Stop Valve (1/2”BSP). Make sure to put the
Mesh Filter between Stop Valve and incoming water piping.
3. If in any case, the Stop Valve is not used or omitted, make sure to put the Mesh Filter
between the heater unit inlet pipe and incoming water pipe.
4. Turn on the water mains to drain out all plumbing dirts, at the same time fill up the
heater tank. THE HEATER TANK MUST BE FILLED UP WITH WATER BEFORE TURNING
ON THE ELECTRICITY SUPPLY TO PREVENT ANY DRY BURNT DAMAGE TO THE
HEATING ELEMENT.
5. Connect the PVC Hose and Handshower to the outlet of Heater, be sure to put in the Washer
6. Hook the Handshower to the Sliding Rail Shower Holder and adjust to your ideal position.
7. Check if any water leakage.
8. Do not use white tape during piping installation.
• THE WATER INLET AND OUTLET MUST BE INSTALLED CORRECTLY , OTHERWISE IT
MAY CAUSE A DAMAGE TO THE HEATING ELEMENT.
• DO NOT APPLY PLUMBING CEMENT ON CONNECTION. WHENEVER NECESSARY,
USE ONLY THREAD OR SEALING TAPE.
• THE WATER INLET OF THIS APPLIANCE SHALL NOT BE CONNECTED TO THE INLET WATER
OBTAINED FROM ANY OTHER WATER HEATING SYSTEM.

1. This appliance must be EARTHED. Improper grounding could cause electrical shock.
2. Remember to SWITCH OFF at mains before carrying out any electrical work.
3. Refer to the previous TABLE 1 for the correct cable size.
4. Use double coated exible cable having nominal cross-sectional area between 2.5mm².
5. Lead the power cable from the MCB to a“ON/OFF”double pole linked switch having
a contact separation of at least 3mm in all poles outside the bathroom, then lead a
cable connected to terminal block inside the unit. (Fig.4)
PROCEDURE:
1. Insert the cable through‘A’for side entry or‘B’for wall embedded cable by cutting
a hole through the source cord rubber holder. (Fig.5)
2. Connect the cable to Terminal Block and fully tighten them as follow
BROWN or RED — LIVE (L)
BLUE or BLACK — NEUTRAL (N)
GREEN or GREEN/YELLOW — EARTH ( )
3. When replace back the Front Cover, please take note the below procedure:
- To ensure the correct position, turn the Temperature VR Knob insert to OFF position
as shown in Fig A. (at the Heater Base)

Fig. 8
1. Turn on the water supply and Stop Valve, the water will ow through the Handshower.
2. Switch on the electrical supply.
3. Turn the Temperature Control Knob to‘ON’, the Yellow Indicator light (Power)
will turn on, hot water will ow out within a few seconds. The more Temperature
Control Knob being turned in clockwise direction, the hotter the shower is.
4. The shower might not be hot enought even at‘MAX’position if incoming water
supply from the mains is too cold or pressure water is too high. In this case, you
may adjust the Stop Valve to reduce the water inow in order to get the desired
showering temperature.
5. Check the Built-in ELCB as following:
- Press the "TEST" button, the Built-in RCD should trip and cut o the power
supply, the Earth/RCD LED indicator should blink red.
- Press the "RESET" button, the heater unit should resume normal function.
All LED indicators should light up.
If procedures stated above prevailed, the ELCB is functioning in normal condition.
6. Switch OFF the electricity supply after shower.
7. For Pump Models: Turn the Pump Knob to test on Pump’s functionality.
If the shower is not hot enough, you may adjust the stop valve until the desired
shower temperature is obtained.
