SECURITY CHARACTERISTICS

The max inlet pressure is 0.8MPa.

• Following warming sentences:
  If the supply cord is damaged. it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

• The pressure-relief device is to be operated regularly to remove lime deposits and to verify than is not blocked.

• CAUTION: In order to avoid a hazard due to inadvertent resetting of the thermal cut-out, this appliance must be not supplied through an external switching device, such as a timer, or connected to a circuit that is regularly switched on and off by the utility.

• This appliance can be used by children aged from 8 years and above and persons with reduced physic sensory or mental capabilities or lack of experience and knowledge if they have been given supervision instruction concerning use of the appliance in a sate way and understand the hazards involved. children shall not play with the appliance, cleaning and users maintenance shall not made by children without supervision.

• This electrical water heater must be installed with a mono-directional safety valve at the inlet pipe(blue indicator) when the tank’s pressure is over 0.8 MPa, this will automatically active the safety valve, water will exit at the drain pipe outlet (Diagram1). In any condition, this outlet must not be blocked.
  If there is a need to empty the water in the tank, first, close the mains water. Remove the fixed screw nail on the safety valve. lift up the plastic handle (see diagram 2) to let the water flow out naturally.

THE OPERATING PROCEDURES

• Check all the piping connection for leakage before turning on the electric power of the heater.
• Make sure that the tank is fully filled up with water, otherwise it will cause the heating elements to be damaged.
• Turn on the mains electrical power supply and then adjust the temperature knob clockwise for higher temperature and anticlockwise for lower temperature.
• The water heater needs to be turn on for a certain period of time to reach the acceptable temperature.
• During the heating process, it’s normal fo see a slight drip at the safety valve. Please do not cover up the safety valve outlet hole.
• Connect this outlet hole to a discharge pipe. Water may drip from the discharge pipe of the safety valve, therefore this pipe must be exposed to the atmosphere.
• The safety valve is to be operated regularly (preferably at least every six months) to remove lime deposit and to ensure that it is not blocked.

PRODUCT STRUCTURE

INSTALLATION INSTRUCTIONS

• The installation for electrical and plumbing work must be carried out by qualified personnel, according to the installation instructions and in compliance to the local authority regulations.
• Unit has to be installed as near as possible to the service points, in order to reduce heat loss along the pipes. To facilitate maintenance, allow a distance of 50cm for easy access to the electrical parts.
• This electrical water heater should be mounted on a solid cement wall, preferably where it is close to the power source’s sockets and water source.
• Please use our company’s fitted accessories to mount this electric water heater.
• Before determining the bolt hole’s position, you should ensure that the heater is more than 200mm from the ground or ceiling board. This will leave space for maintenance when necessary.
• Assembling method: After selecting the proper fixing positions, use the inflating bolt to secure the hanging board firmly, then hook the electric water heater. (Diagram )

PIPE CONNECTION

• All piping parts are BSP 1/2”. Wind some white tape at the thread sector of the inlet pipe (marked blue).
• Fix the safety valve to the inlet pipe and then connect it to the cold water pipe of the mains.
• Install a water drainpipe to the safety valve to drain away water discharge. (drain pipe joint outlet — diagram 5).
• Install the drainpipe in a continuously downward direction and in a frost free environment.
• Connect the hot water pipe (marked red) to the outlet pipe.
• Do not over-tighten the safety valve and all pipes joint as it may cause damage to the joints.
• Make sure all pipes are clean before installing the taps and showers.
