Installations

Installations Cautions

• When installing the water heater, it should leave a certain amount of space (at least 300mm) to facilitate future maintenance. If the water heater is embedded in the gusset plate during installation, the gusset plate near the maintenance cover side should be movable to facilitate disassembling the maintenance cover during maintenance.
• It should ensure that the inlet pressure of tap water is not less than 0.05MPa and the maximum pressure does not exceed 0.75MPa.
• Electric water heater should be installed indoors, where the ambient temperature is above 0°C. The pipeline should be centrally arranged. The hot water outlet should not be too far from the use place of hot water. If it exceeds eight meters, the hot water pipeline should be insulated to reduce the heat loss.
• The wall where the water heater is hung should be sturdy and secure to withstand four times the weight of the water heater after filling with water. If it is a non-bearing wall or hollow brick wall, it is necessary to take appropriate protective measures, add brackets, use crossing screws, and install back boards.
• The installation location of the electric water heater should be selected a place that is convenient to use, maintain and have a floor drain. If the water tank or water pipe leaks, it will not cause damage to nearby or lower level facilities. The installation position try to avoid installing on the toilet, bathtub, washbasin and door frame. So that it does not create a feeling of overwhelming or insecurity for the user.
• Do not reverse the inlet and outlet pipes. The safety valve should be installed in the designated position and should not be altered privately. The pressure relief hole of safety valve should be kept in contact with atmosphere. Do not block it.
• For security, water heaters should use independent sockets (multifunctional sockets are prohibited) and be reliably earthed. And the quality of the socket should be in line with  local national standards. It is strictly forbidden to use the water heater without reliable earthed.
• The power outlet of the water heater should be placed in a dry place where water cannot shower, so as not to affect the normal work of the machine (preferably with a waterproof box).
• Use an electro probe to measure whether the live wire and neutral wire are connected in reverse. After confirming that the machine has been filled with water, the joints do not leak and the power supply meets the requirements, then it can be heated by electricity.
• For avoiding the danger of accidental reset of the over-temperature thermostat, the water heater must not be powered by external switching devices such as timers. It shall not be connected to a circuit that is frequently switched on and off through other settings.
• In order to prevent the occurrence of accidents, the accessories provided by our company must be installed and must not be replaced or substituted by yourself. If the accessories are damaged, it must be notified to our Maintenance Department for repair and replacement with the accessories provided by our company. If the above matters are not complied with, we will not be responsible for any direct or indirect loss caused by the accident.

• In order to facilitate the installation and disassembly of the water heater, it is recommended that the water heater inlet and outlet pipes are installed at the appropriate location  with G1/2 loose joints respectively. Determine the location of the water supply. Connect the water inlet pipe and the tap pipe to the water place respectively. Fill the inner tank with water, check whether the water line is leaking. If there is a leak, it needs to be reconnected.

Warning: It is important to make sure that the hooks on the back of the machine (F1 Serie) or the wall bracket (TF7/VH3 Series) are securely hung on the wall-mounting frame (F1  Serie) or expansion hook (TF7/VH3 Series) before releasing the hands to prevent the water heater from falling and causing personal injury or property damage.

Installation of Safety Valve

• Install the safety valve (its connection is G1/2) with a rated pressure of 0.80MPa in the direction of the arrow on the safety valve (arrow pointing to the water heater) to the inlet pipe. When the water heater is heated by electricity, the water inside the tank is heated and expands. In order to reduce the water pressure inside the tank, a small amount of  water droplets will flow from the pressure relief hole of the safety valve. The pressure relief hole should be kept open to the atmosphere and should not be blocked.

• The pressure relief hole of the safety valve can be connected to the drain pipe. The installation method of the drain pipe of the safety valve is as follows: Screw the one end of the  drain pipe to the pressure relief hole of the safety valve. The drain pipe connected to the safety valve should be kept inclined installed in a frost-free environment in a continuous downward way, and the water overflowing from the drain pipe should drain into the floor drain.
  Note: Drain pipes are sold separately.
