Methods of installation

Note:
Please ensure to use the accessories provided along with the product to install this water heater. The heater cannot be hung on the support until it has been confirmed to be firm and reliable. Otherwise, the heater may drop off from the wall, resulting in damage to the heater, and even serious accidents. When determining the location of the bolt holes, it shall be ensured that there is a clearance not less than 0.2m on the right side of the heater. This may be required during the maintenance of the heater.

• This water heater shall be installed on a solid wall. If the strength of the wall cannot bear the load equal to two times the total weight of the heater filled fully with water, it is then necessary to install a special support.
• After selecting a proper location, determine the positions of the two holes used for expansion bolts with a hook (20 mm). Make two holes in the wall with the corresponding depth and size matching the expansion bolts attached to the heater, insert the bolt, turn the hook upwards, tighten the nuts to fix firmly, and then hang the water heater on it (see Fig.3).
• Install the supply socket on the wall. The supply socket should be 3 pins, single phase,230V/16A.lt is recommended to place the socket on the right side above the heater. The height of the socket to the ground shall not be less than 1.8m (see Fig.4).
• If the bathroom is too small, the heater can be installed at another place. However, in order to reduce the pipeline heat losses, the installation position of the heater shall be as near as possible to the bathroom.

Connection of pipelines

• The dimension of the multifunction valve and the inlet /outlet pipe is ½”BSP.
• Connection of multifunction valve: install the multifunction valve with the heater on the inlet of the water heater.
• In order to avoid leakage when connecting the pipelines, the rubber seal gaskets provided with the heater must be added at the end of the threads. Ensure leakproof joints.

Multi-outlet connection

• If the users want to install a multi-way supply system, refer to the method shown in Fig.5 for the connection of the pipelines.

Illustration of Control Panel

Display:

1. A two-digit digital screen displays the set temperature or actual temperature.
2. “Heating/Warming” function light: the red light is on for normal heating, and it flashes under antifreeze heating. The green light is on when keeping warm.
3. “Electronic Anode” function light: The light is always on when the electronic magnesium rod is working normally, and it flashes when it is abnormal.
4. “wifi” function light: it lights up according to the actual situation. If it is not connected to the network for a long time (30s), the WIFI icon does not light up.

Operation instruction:

1. “Power” button: Shortly press this key in the standby state after power on, the system is turned on immediately with the previous reserved parameters. When the machine is on, press this key and the system will switch to standby. Press and hold for 3 seconds when power is on, it will transfer to the WiFi network mode.
2. “Temp” button: under the instant heating mode, tap this button to increase the set temperature. The temperature would increase by 1 °C each time. Long press the key to increase the data rapidly (5 times/S), the temperature range would be from 30°C to 75°C (it would jump to the lower limit when adjusted to over the upper limit).
3. “Setting” button: When pressing this button after turning on the machine, it could choose “Anti-Bacteria” or “Instant heating” working mode.

Features:

1. Instant heating: under this working mode, after heating to the set temperature value, it will transfer to the warming state, and when the current water temperature drops to the value of 8°C lower than the set value [set temperature -8°C], it will start heating to the set temperature again, and keep the cycle going.
2. Anti Bacteria: under this mode (the temperature is not adjustable), the system will enter the heat preservation state after heating to 80°C, and return to instant heating after 30 minutes of heat preservation.
3. Anti-frost: Under standby mode, when the temperature of the water in the inner tank is lower than 5°C, the anti-frost heating function will be activated, and the “Heating/heat preservation” function light will flash at 1 Hz, and the heating will stop when heated to 10°C and standby; if the machine is on, the system would heat in normal mode.
4. Timing: set the appointment water time via APP, and the water heater will heat to the set value before the appointment time.
5. Smart Mode: The system memorizes the user’s last week’s water consumption habits and automatically adjusts the set temperature.
6. Failure and protection: When there is a dry-heating failure, sensor failure, or overheating failure, the digital screen displays the corresponding failure code, the electric water heater immediately disconnects the electric heating element’s power supply, and any button operation is invalid. Only after fixing the failure with power off, then turning on power again, can the fault protection function be quit.

Cautions

• During heating, there may be drops of water dripping from the pressure release hole of the multifunction valve. This is a normal phenomenon. If there is a large amount of water leak, please contact the customer care center for repair. This pressure release hole shall, under no circumstances, be blocked otherwise, the heater may be damaged, even resulting in accidents.
• The drainage pipe connected to the pressure release hole must be kept sloping downwards.
• 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.
• Unscrew the threaded screw on the multifunction safety valve, and lift the drain handle upwards (See Fig. 7) to drain the water from the inner tank.
• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or related qualified person in order to avoid a hazard.
• 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 the use of the appliance by a person responsible for their safety.

Maintenance

1. Check the power supply plug and socket frequently to make sure that they have good, reliable contact and are well-grounded without overheating phenomenon.
2. If the heater is not used for a long time, especially in regions with low atmospheric temperatures (lower than 0°C), the water inside the heater shall be drained away. This will prevent damage to the heater due to water freezing in the inner container, ( Refer to Cautions in this manual for the method to drain away the water from the inner container).
3. In order to ensure that the water heater operates efficiently for a long time, it is recommended to clean the inner container and the deposits on the electrical heating components periodically.
