WALTON WWH-MVH50L Electric Water Heater User Manual

WALTON WWH-MVH50L Electric Water Heater

Product Information

The WWH-MVH50L is a 50L water heater with a heating power of 220V~ and 75. It has a temperature limiter that cuts off electricity if the water heater is overheated or if the thermostat is damaged. In such cases, manual resetting is required. Non-professionals are not allowed to disassemble the temperature limiter to reset it. Please contact professionals for maintenance. Otherwise, the company will not take responsibility if any quality accident happens because of this. The product also includes a pressure relief valve, a mixing valve, and a shower nozzle.

Methods o f installation

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

Installation

• This electrical water heater shall be installed on a solid wall. If the strength of the wall cannot bear the load equal to two times of the total weight of the heater filled fully with water, it is then necessary to install with special support.
• After selecting a proper location, determine the positions of the two holes used for expansion bolts with hook Make two holes in the wall with the corresponding depth and size matching the expansion bolts attached with the heater insert the screws, turn the hook upwards, tighten the nuts to fix firmly, and then hang the electrical water heater on it (see Fig.2.).
• Install the supply socket in the wall. The supply socket should be 3 pin, single phase, 230V /16A. It is recommended to place the socket on the right above the heater. The height of the socket to the ground shall not be less than 1.8m
• If the bathroom is too small, the heater can be installed at another place. However, in order to reduce the pipeline heat the installation position of the heater shall be as near as to the heater.

Connection

Connection of pipelines

• The dimension of multifunction valve & the inlet /outlet pipe is Y2″ 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 (see fig.3). Ensure leak proof joints.

Multi-outlet connection

• If the users want to realize a multi-way supply system, refer to the method shown in Fig.4 for connection of the pipelines.

Methods of use

• First, open any one of the outlet valves at the outlet of the water heater, then, open the inlet valve. The water heater gets filled with water. When water flows  out of the outlet it implies that the heater has been filled fully with water,  and the outlet valve can be closed.

Note: During normal operation, the inlet valve shall be always kept open. Inset the supply plug into the supply socket, and switch ON.

The POWER indicator will light up, adjust the thermostat suitably the HEATING indicator will light up
The thermostat will automatically control the temperature. When the water temperature inside the heater has reached the set temperature, it will switch off automatically, when the water temperature falls below the set point the heater will be turned on automatically to restore the heating. When the heater is switched off automatically, the heating indicator will switch off.

Cautions

• The supply socket must be earthed reliably. The rated current of the socket shall not be lower than 16A. The socket and plug shall be kept dry to prevent electrical leakage.
• The installation height of the supply socket shall not be lowerthan 1.8m.
• The wall in which the electrical water heater is installed shall 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 shall be adopted.
• The multifunction valve attached with the heater must be installed at the cold water inlet of this heater (see Fig. 5).
• When using the heater for the first time (or the first use after maintenance), the heater cannot 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.
• 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 training or Instructions concerning use of the appliance by a person responsible for their safety.
• 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 customer care center for repair . This pressure release hole under no circumstances, should 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 750C, 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 thread screw on the multifunction safety valve and lift the drain handle upwards). (See Fig.6) to drain the water from the inner tank.
• 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.
• If any parts and components of this electrical water heater are damaged, please contact customer care center for repair.

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 the regions with low atmospheric temperature (lower than OOC), the water inside the heater shall be drained away. This will prevent the damage to the heater due to water freezing in the inner container, ( Refer 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 long time, it is recommended to clean the inner container and the deposits on the electrical heating components pericxiically.
4. It is recommended to examine the anode protection materials every six months or so. If all the material has been consumed, please replace with the new material.
5. The temperature limiter cut off electricty if water heater is overheated or thermostat is damages.Manual resetting is needed. Non-professionals are not allowed to disassemble temperature limiter to ræet . Please contact professionals to maintain.Otherwise our company will not take responsiblity if any quality accident happens  because of this.
