2 TRIPLE SAFETY SYSTEM (TSS)

The Triple Safety System (TSS) in the heater incorporates the Pressure Relief Valve, the Thermostat with Safety Cut-out and Thermal Fuse.

1. Pressure Relief Valve

The Pressure Relief Valve prevents excessive pressure built-up in the storage tank and must not be removed or replaced. In the event the pressure in the storage tank exceeds 0.9 ± 0.1 MPa ( 9 ± 1 Bar), the drain valve will operate and vent the water through the overflow pipe which must not be closed or blocked. The pressure discharge Lever makes it easy to discharge water from the storage tank when changing the heating element or remove any blockage at the drain valve.

IMPORTANT

Operate the pressure discharge level at least once year to prevent blockage at the drain valve. Closed or blocked drain valve may cause serious damage to the heater tank and void the warranty.

1. Thermostat

CAUTION: The heater must not operate without the Thermostat.

i.) Horizontal Model

The Thermostat incorporates a pre-set temperature and a Safety Cut-out with manual reset. Under normal operation the Thermostat cuts out at approximately 65°C to 70°C (depends on requirement) which is the most economical setting with lower heat loss and less lime scaling. This is indicated by the Red Lamp going off and comes on again when the water temperature drops as hot water is drawn off. Thus maintaining a constant supply of hot water.

ii.) Vertical Model

A control knob is provided on the surface of the installation cover for adjusting the temperature of the water heater from 'OFF' to 70°C (Low - Med - High). Under normal operation the Thermostat cuts out at the set temperature - Low (about 40°C), Medium (about 55°C), High (about 70°C).

Economical Mode

When the hot water consumption required is not in large volume, setting Adjustable Thermostat at Medium will minimize the electrical consumption.

iii.) Safety Cut-out (Horizontal & Vertical Model)

The Safety Cut-out will break the circuit to the heating element in any event the water temperature in the storage tank becomes excessively high (95°C). This is indicated by the Red and Green Lamps going off.

CAUTION: Should this happen, switch off the heater electrical supply point and contact our nearest service centre or sales agent. Do not attempt to repair the heater yourself.

1. Thermal Cut-Off

The Thermal Cut-Off helps to prevent the heating element from being damaged in any event the heater operates without water.

Optional Built-In Heat Elevator

This energy saving Heat Elevator uses patent pending magnetic technology to accelerate convective heat transfer of fluids. The result is faster water heating time and ensures a more constant and uninterrupted flow of hot water.

3 INSTALLATION INSTRUCTION

3.1 WATER HEATER INSTALLATION

IMPORTANT

- Installation should be carried out by qualified personnel with close reference to the installation manual and compliance to the local authority.

- All plumbing works must be completed and heater tank fully filled with water before proceeding to electrical connections. This will prevent any damage to the Heating Element and Thermal Fuse.

• This appliance must be installed indoor only.

- Do not use ABS or PVC plastic pipes for the inlet and outlet pipe connections. Use only recommended Stainless Steel, Copper or Polymer pipe which can withstand high temperature and pressure.

- Do not install in area where the water supply EXCEED 20mg/LITRE (20ppm) OF CHLORIDE as this will cause corrosion to the stainless steel heater tank and void the warranty.

1. Select a suitable location for convenience of water and electrical supply as well as easier for future maintenance. Make sure the location is free from water splash.

2. In case the water supply is from the water tank, the water heater should be connected to a booster pump (minimum 0.15MPa/1.5bar), in order to have sufficient hot water flow.

6 OPERATION

IMPORTANT

• Make sure the heater tank is filled with water before switching on the electrical supply. Failure to do so will damage the heating element and void the warranty.
- To avoid the danger of scalding when operating this water heater, always turn on the cold water faucet first and then adjust the hot water faucet to get the desired water temperature.
- This appliance is not intended for use by young children or infirm persons without supervision.

The first operation and heating of the appliance must be observed by the installing technician after water and electrical connection have been made and heater tank filled with water, before switching on the electrical supply. The standard 3kW heating element (optional 1.5kW) together with automatic regulating thermostat (horizontal model) and an adjustable thermostat (vertical model), heat up water faster and keeps electric consumption to a minimum. In addition, the compact polyurethane foam insulation keeps the hot water longer and ready for immediate use.
