4.10 DO NOT APPLY PLUMBING CEMENT ON CONNECTION. WHENEVER NECESSARY, USE ONLY THREAD OR SEALING TAPE.

ELECTRICAL INSTALLATION

WARNING!

5.1 This Electric Water Heater must be earthed. Improper grounding could cause electrical shock.
5.2 Remember to SWITCH OFF the power supply before carrying out any electrical work.
5.3 Refer to TABLE 1 for the correct cable size.
5.4 Use double insulation cable of over 2.5mm² for 2.4kW, 3.5kW 3.8kW, 4.5kW 4.8kW models and 4mm² for 3.6kW and 6.0kW model.
5.5 Lead the power cable from 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 to the terminal block inside the Electric Water Heater (Fig. 4)

PROCEDURE

5.6 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’. (Fig. 6)

5.7 Connect the cable as following: (Fig. 5)
BROWN or RED –LIVE (L) BLUE or BLACK –NEUTRAL (N) GREEN or GREEN/YELLOW –EARTH ( )
5.8 Clamp the cable to the correct position. The technician need to confirm the wire before installation. CHECK IF THE WIRING CONNECTION IS CORRECT and replace the cover.
5.9 When putting back the Front Cover, please take note of the procedure shown below :

• Ensure the position is correct, turn the Temperature Control Knob Insert to OFF position as shown in Fig.A (At the Heater Base)
• Install the Front Cover,turn the Temperature Control Knob to OFF position to align with the VR shaft as shown in Fig.B (At the Front Cover)
  5.10 Fix the Temperature Control Knob and screw ‘A’ (Fig. 2).

 TEST RUN

7.1 Turn on the water supply and 3 in 1 Stop Valve, the water will flow through the Handshower.
7.2 Switch on the power supply. The 3 LED Indicator light shall run ON/OFF 3 times in sequences to indicate the set are self checking. If the Electric Water Heater is not earthed properly, the Earth Led indicator light will OFF, during usage or standby. Earth Led indicator light also OFF if Live & Neutral reverse connection.
7.3 Turn the Temperature Control Knob to ‘ON’, the Red indicator light (HEATER POWER) will turn on, (ELCB/Power Led indication are combine Led indicator light- ELCB is GREEN & Power is RED) hot water will flow out within a few seconds. The more Temperature Control Knob being turned in clockwise direction, the hotter is the water.
7.4 The Electric Water Heater might not be hot enough even at the ‘MAX’ position if the incoming water supply from the mains is too cold or the pressure of water is too high. In this case, you may adjust the 3 in 1 Stop Valve to reduce the water inflow in order to get the desired showering temperature. (Recommended flow rate of below 6litre/min)
7.5 Check the Built-in ELCB as follows:

•  Press the “TEST” Button, the Built-in ELCB should trip and cut off the power supply, ELCB and Power Indicators should light off.
• Press the “RESET” Button, the 3 LED
  Indicator light shall run ON/OFF 3 times in sequences to indicate self-checking as in 7.2 above and the Electric Water Heater should resume normal function, the Green LED Indicator should light on. If procedures stated above prevailed, the ELCB is functioning in normal condition.
  7.6 The height and direction of the Shower The holder are adjustable by releasing the shower holder knob clockwise and anticlockwise.
  7.7 Move the Handshower to the desired angle. A ratchet mechanism in the Shower Holder will hold the Handshower in selected position.
  7.8 It is unnecessary to turn the Temperature Control Knob to the “OFF” position when the Instant Hot Shower is not in use.
  7.9 Switch OFF the power supply after shower.
  7.10 For Pump model: The pump will auto ON when power ON and 3 in 1 stop valve open (and there is water supply)
  7.11 Booster Pump Function: After the incoming power supply is ON, and water supply flow-through 3 in 1 stop valve while open position but the water flow rate is not sufficient to activate the flow sensor, Booster Pump Function can be useful to help to increase the incoming water flow rate. Press the pump button to activate the booster pump function. The booster pump function will be ON to increase the incoming water flow rate. While the Booster Pump Function is working and the incoming water flow rate can be maintained above flow sensor activation level, the Electric Water Heater will be resumed working continuously as normally. If the incoming flow rate can not be maintained above 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 is too low. (Advisable to avoid applying Booster Pump Function to increase the incoming water flow rate more than 3 times of each showering).

 HANDSHOWER SPRAY

This Innovative adjustable Handshower has 5 different spray patterns (STANDARD, JUMBO, SOOTHE, MIX and MASSAGE. The patterns are described as follows:
