How to install the water heater?

Installation must be performed by a qualified professional. Ensure the wall can support the weight, connect to cold water supply and hot water outlet, and install the pressure relief valve. Refer to the manual for detailed steps.

What is the recommended water pressure?

The recommended water pressure is between 0.2 and 0.6 MPa (2-6 bar). If pressure exceeds 0.6 MPa, install a pressure reducing valve.

How to adjust the temperature?

Turn the thermostat knob located near the bottom of the heater. Use a screwdriver to adjust to desired temperature (max 75 °C). Disconnect power before adjusting.

Why is there no hot water?

Check if power supply is connected and the circuit breaker is on. Also verify that the thermostat is set correctly and the heating element is functioning. If issues persist, contact a technician.

How often should I replace the anode rod?

The anti-corrosion anode should be inspected every year and replaced every 2-3 years to prevent tank corrosion. Signs of heavy depletion indicate replacement is needed.

Can I use the heater without the pressure relief valve?

No, the pressure relief valve is essential for safety. It prevents excessive pressure buildup. The heater must never be operated without it.

What maintenance is required?

Periodically check the pressure relief valve for operation, flush the tank to remove sediment, and inspect the anode rod. Refer to manual for detailed maintenance schedule.

Is the heater suitable for hard water areas?

Yes, but hard water may cause scale buildup. Regular flushing and using a water softener can help maintain performance and extend lifespan.

What does the energy efficiency class mean?

Class C indicates moderate energy efficiency. To save energy, set thermostat to 60 °C and insulate exposed pipes. Use during off-peak hours if possible.

How to drain the water heater?

Turn off power and close the cold water supply. Connect a hose to the drain valve, open the valve and a hot water tap to allow air in. Drain completely before servicing.

1. CAUTIONS

Before installing this water heater, check and confirm that the earthing on the supply socket is reliably grounded. Otherwise, the electrical water heater can not be installed and used. Do not use extension boards. Incorrect installation and use of this electrical water heater may result in serious injuries and loss of property.

Special Cautions

- The water heater 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 instructions concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the heater.

- The wall in which the electrical water heater is installed must be able to bear the load more than two times of the heater filled fully with water without distortion and cracks. Otherwise, other strengthening measures must be adopted.

- The supply socket must be earthed reliably. The installation height of the supply socket must not be lower than 1.8m. The rated current of the socket must not be lower than 16A. The socket and plug must be kept dry to prevent electrical leakage. If the flexible power supply cord is damaged, the special supply cord provided by the manufacturer must be selected, and replaced by the professional maintenance personnel.

- The maximum inlet water pressure is 0.5MPa; the minimum inlet water pressure is 0.1MPa, if this is necessary for the correct operation of the appliance.

- When using the heater for the first time (or the first use after maintenance), the heater can not be switched on until it has been filled fully with water. When filling the water, at least one of the outlet valves at the outlet of the heater must be opened to exhaust the air. This valve can be closed after the heater has been filled fully with water.

- The pressure relief valve attached with the heater must be installed at the cold water inlet of this heater, and make sure it is not exposed in the foggy. The water may be outflowed from pressure relief valve, so the outflow pipe must open wide in the air. In order to drain away the water inside the inner container, it can be drained away from the pressure release valve. Twist the thread screw of the pressure release valve off, and lift the drain handle upwards(See Fig.1). The drainage pipe connected to the pressure release hole must be kept sloping downwards and in a frost-free environment. The water may drip from the discharge pipe of the pressure-relief device and that this pipe must be left open to the atmosphere.

- During heating, there may be drops of water dripping from the pressure release hole of the pressure relief valve, this is a normal phenomenon. The pressure release hole shall not be blocked under no circumstances, otherwise, the heater may get damaged, even resulting in accidents. If there is a large amount of water leak, please contact customer care center for repair.

- The pressure relief valve need to be checked and cleaned regularly, so as to make sure it will not be blocked.

- Since the water temperature inside the heater can reach up to 75°C, the hot water must not be exposed to human bodies when it is initially used. Adjust the water temperature to a suitable temperature to avoid scalding.

- If any parts and components of this electrical water heater are damaged please contact customer care center for repair.
