Installation Requirements for Series E and Series S

When installing a Storage Water Heater, it is essential to ensure the following 4 environmental conditions are met for optimal performance:

1. Wire Conductor
   
   a. Provide a dedicated circuit with a power outlet rated at 240V. Amperage of 13A, 16A, or 20A (depending on the kW power rating of the model). The standard calculation formula for current: Power (W) / Voltage (V) = Current (I), which is in Amperes (A). For example, a model with 3kW has a current of 3000W / 240V = 12.5A. In theory, a 13A power switch is suitable and won't overload. However, according to Malaysia Suruhanjaya Tenaga’s guidelines, the installation of electrical products with ratings of 3kW, 3.8kW, and 4.5kW requires a 20A power outlet socket for optimal safety protection.
   
   b. Wire diameter of at least 4mm²
   
   c. Must be permanently earthed
   
   💡 Note: If there is already an existing power supply dedicated to the water heater in your home, you can typically find the maximum current load (in Amperes) it supports on the switch outside the bathroom. If no power supply has been installed yet, please allocate a 20A supply for the Esio Storage water heater.
   
   
2. Hot and cold water pipes
   To ensure seamless connectivity between the water source and the storage water heater, we kindly ask for your confirmation regarding the pre-embedding of both cold and hot water pipes within your residence.
   
   
3. Drainage
   To address potential drainage and pressure release during the heating process of the storage water heater, it is imperative to ensure that the installation location is equipped with a drainage pipe or drainage hole.
   
   
4. Wall Structure
   To ensure the stability of the installation and safety of use, the wall structure must be made of concrete or reinforced concrete (RC) material.

For users in need of the Online Assessment Service, please contact Esio Malaysia WhatsApp and provide complete photos of the installation environment and power switch for evaluation by Customer Service Representatives.

• Please ensure that the installation space and environment photos include the following elements:
• Hot and Cold water pipes
• Wire conductor（240V and wire diameter of at least 4mm²）
• Drainage hole

• When taking a photo of water heater power switch, kindly ensure that the following elements are clearly visible:
• The amperage rating on the switch
• The switch is for an independent dedicated circuit

*Furthermore, to ensure precise assessment of the installation space requirements, kindly share the overall width and height of the desired installation space. When taking photos, kindly ensure the exclusion of any piping or miscellaneous items to ensure assessment accuracy.
