FEATURES

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 of 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 of power whenever the water temperature rises to 55°C (Anti-scalding) and 90°C (Abnormal overheat).

5. IP25 Splash Proof
   Livinox’s T-Series 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 T-Series 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.

   Note: When removing the unit from package, small amount of water may be found inside. This is normal as the unit is tested during manufacturing process.
   CAUTION !

2. 1Installation must be carried out by a qualified personnel and in compliance to the local authority regulations.
   2.2 This heater must be permanently connected to the direct main current supply. The use of a plug and socket is not recommended.
   2.3 For the correct size of wire conductor corresponding to different electrical loading, please refer to Table 1.
   2.4 This heater operates at a minimum water flow rate of 2.0ltr/min and maximum working pressure of 6 bars. For direct connection to the water tank, the heater must have a minimum distance of 1.0m below the water tank.
   2.5 This heater will not function if there is insufficient water flow (min 2.0ltr/min) to trigger the flow switch.
   2.6 The built-in ELCB will automatically cut off the power supply in case there is a current leakage of at least 15mA.
   2.7 The thermostat will automatically cut off the power supply if it has sensed an abnormal rise in water outlet temperature.

TEST RUN

1. Turn on the water supply and Stop Valve, the water will flow through the Handsomer.

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 flow 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 enough 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 inflow 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 off 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.

HANDSHOWER SPRAY ACTION

This innovative adjustable Handsomer actions are described as follows.

Clean the Handsomer Head holes by using the soft brush from time to time. (Recommended once a week) Note: Take care not to damage the holes of the Handsomer Head during cleaning.

MAINTENANCE

Read the section ‘IMPORTANT SAFETY INFORMATION ‘first

1. TESTTHE’RCD’REGULARLY
   (This procedure is highly recommended to test at least once a month)
   Turn on the electricity and water supply, all LED indicators will light up. If the
   Temperature Control Knob is in “ON” position, the power LED will light up also.
   Press the RCD button, the RCD/Earth lamp should turn RED and start blinking.
   Press the Reset button to resume back the electricity supply.
   WARNING!
   If the RCD or HEATER lamp does not go off when you press the RCDTest button, SWITCH OFF the mains supply and contact your sales agent for repair. Special skill is required for repair.
   NEVER try to repair the unit by yourself.

2. CLEANING PRECAUTION!
   Do not use thinner, alcohol, petrol or any other organic solution to clean the set, use only a damp cloth with mild detergent.

3. CLEAN THE FILTER REGULARLY (Fig. 9 & Fig. 10)
   
   
   There are two filter located at the stop valve, one is Mesh Filter (installed at the incoming water supply), another one is the built-in filter as shown in Fig. 10).
   Clean the Mesh Filter regularly to prevent blockage. Remove the built-in filter by turn it anti-clockwise as shown in Fig. 9. Take out the Filter and flush it with water to remove any trapped sediments. (as shown in Fig. 1 O)
