Mode!: Smart-18EP / 18E Water supply from house hold

GENERAL INFORMATION

WATER

1. The heater works at a minimum water flow rate of 3 liters/min. Note that for heater model without built-in pump an incoming water with consistently flow rate of 5 liters/min and above would excel its performance.
2. A typical plumbing connection is shown in diagram 2.

SAFETY:

Note: An approved type of Residual Current Device (RCD) of 10mA sensiti be installed in conjunction with the heater. ity should

1. The built-in Earth Leakage Sensing Device (ELSD) would cut off the power supply to the heater in the event of current leakage of as low as 15mA.
2. Upon power on at mains, the heater will perform 10 seconds ‘self-test routine. If the ELSD is in_proper working condition after the ‘self-test, the AUTO TEST indicators will light up GREEN and heater will be in power. If ELSD is faulty, its AUTO TEST indicators will blink RED and power will be cut off from heater.
3. The built-in Line Fault Detector will indicate ‘GREEN’ light if wiring is done correctly or ‘RED” light if improper electrical wiring is detected.
4. The heater operates when there is sufficient water to trigger the Flow Switch.
5. The Thermal cut-out would automatically breaks off the power supply if there is abnormal rise in shower temperature.
6. Heater casing designed to high degree of protection IP25 prevents water from entering into the heater during shower.

IMPORTANT NOTE:

1. This heater is tested suitable for use in the shower cubicles. However, do not install the heater unit where i consistent spray directly over the unit.
2. If the heater’s ELSD trips during normal operation, switch off the mains supply and contact the sales agent for repair(s).
3. If the Auto Test and Line Fault Indicator indicate RED light, switch off the mains supply and contact a qualified electrician to check the electrical supply line (refer Page 11 for possible cause(s)).
4. In the event the heater malfunctions, never attempt to repair the unit yourself.
5. The outlet point of this heater, hose and handshower act as a vent. They must not be blocked, obstructed or modified in any way. Fittings not recommended by manufacturer must not be connected. The use of unapproved accessories may not only affect its performance and salely of the user but also invalidate its guarantee.
6. If there is a sudden reduction of incoming water, the shower temperature will increase. This does not indicate the fault of the heater. Adjust the Temperature Control Knob (to reduce heating power) or Regulator Unit (to increase flow) in order to get the desired shower temperature.
7. Always test the water spray temperature with your hand before stepping into the shower.
8. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
9. Do not leave your children, elderly, infirm or disable persons unattended in the shower.

INSTALLATION PROCEDURE

IMPORTANT:

•  All plumbing work should be completed before proceeding to electrical wiring connection.
• Metalic / Chromed hose and conductive control valve shall not be used (in Malaysia only- Malaysian government’s regulations. Optional for others).
• Heater outlet shall not be connected to any tap or fittings not recommended by manufacturer.
• The – heater unit must be installed on solid wall to avoid the possil y of distorting the unit.
• Inlet and Outlet connections of the heater should not be reversed.

Decide the mounting position

a) Tum off the water source.
b) Remove screw at the bottom of the heater.
c) Remove Heater Cover by lifting the bottom upward.
d) Mark out 4 mounting points on the wall.

lift up Cover from bottom

Note:
It is recommedded that mount the bottom of the heater be 1.50 meters /5 feet above the floor of the bathroom. However the height of the installation level is at the discretion of the user.

Mounting of the heater

a) Drill the 4 holes with 5.0mm diameter drill bit.
b) Putin the wall plugs and install the heater to the wall with screws provided.

Shower Accessories Installation

a) Fix the Shower Holder and Rail Supports (Top and Bottom) on to the Sliding Rail.
b) Mark the positions of the 2 holes of the Rail Supports – be sure that the top portion is in level or not higher than the top of the heater.
c) Drill the holes and mount the shower accesories \ with wall plugs and screws provided. Insert the Rail | \ Support Caps on to the Rail Supports.

Connection of heater Inlet and Outlet

a) Connect Stop Valve to heater Inlet with use of the rubber seal provided.

b) Connect incoming water supply to Stop Valve. If necessary make use of the == sealing tape to prevent water leaking.

c) Connect Flexible Hose to heater Outlet (Do not connect the other end of flexible hose to handshower at this stage).

d) Turn on the water supply to drain out all the plumbing dirt and to fill up the heater tank. (This step will prevent damage to Heating Element.)

e) Connect the other end of flexible hose to handshower – be sure to put in the Filter Mesh Washer in order to prevent dirt from entering the handshower.

Note:

• Do not apply excessive force to tighten any of the connections.
  

• Excessive force may cause damage to the connector.
  

• Do not bend the Flexible Hose or install any accessories which can block the water flow at heater outlet.
  

Electrical Connection

CAUTION :

Make sure the electrical mains is off before carrying on the electrical work

a) Insert electrical cable through the rubber grommet for side entry or wall embedded entry.
b) Connect cable to Terminal Block and fully tighten them as follows:

RED or BROWN
LIVE (L)
BLACK or BLUE……… NEUTRAL (N)
GREEN/YELLOW or
YELLOW/GREEN EARTH()
c) Replace the Heater Cover

1. To ensure correct position, turn the Electronic Control Unit and Pump Control Unit (at Heater Base) to the off position (as shown in picture).

2. Install the heater cover and ensure that the Temperature Control Knob and Pump Control Knob are aligned (point to ‘OFF) to their control unit accordingly.

3. Secure the screw as shown.

Test Run Of Heater

a) Turn on Stop Valve.
b) Switch on heater switch. The ‘AUTO TEST’ and ‘LINE FAULT INDICATOR’ will light up. Proceed to step (c) if ‘AUTO TEST’ and ‘LINE FAULT INDICATOR’ displays green light.

CAUTION:
Stop using the heater and check the wiring if ‘AUTO TEST’ and ‘LINE FAULT INDICATOR’ displays RED light (refer page 11 for possible causes).

c) Turn on the Temperature Control Knob. The ‘HEATER’ indicator will light up. The water should be warm in a few seconds.
d) The water would get warmer as the Temperature Control Knob is turned clockwise.
e) Check the built-in ELSD as follow:

• Press ‘TEST’ button: unit should trip and cut off power supply.
• Press ‘RESET’ button: unit should resume normal function.

If the above mentioned steps prevail, the ELSD is functioning normally.

OPERATING PROCEDURES

1. Switch on the heater switch outside the bathroom. The ‘AUTO TEST’ and ‘LINE FAULT’ indicator would light up.
   CAUTION:
   “AUTO TEST’ and ‘LINE FAULT INDICATOR’ must indicate green. Otherwise the unit must not in use and contact agent for repair

2. Turn on the Stop Valve. Adjust the Regulator Unit for suitable water shower volume.

3. Turn on Temperature Control Knob. The ‘HEATER’ indicator would light up. The shower would get warmer as the knob is turned clockwise from ‘ON’ to ‘MAX’.

4. Normal cold shower can be selected by setting the Temperature Control Knob to ‘OFF’ position.

5. Switch off the heater switch when not in use.

Note:

•  The shower water may not be hot enough even at ‘MAX’ in areas where the water pressure is exceptionally high and cold. This can be remedied by reducing the water inflow or replacing the unit with one that is of higher power (if it is approved by relevant authorities).
• The built-in Pump can be independently controlled by using the Pump Control Knob. In low pressure areas (below 15 p.s.i.), adjust pump speed to obtain desired spray of water. If water pressure is high (over 15 p.s.i.), turn “OFF” the Pump Control Knob to achieve hotter shower. (Model Smart 18EP/181)
• The Pump Activator is specially designed for low pressure areas where the water pressure is too weak to trigger the Built-in shower Pump. Just press the Pump Activator Button and the Shower Pump will spring into action. (Model Smart 18EP/18i)
• It is recommended that the pump be operated at intervals of 30 minutes with 30 minutes rest in between. (Model Smart 18EP/18i)
