  • Installation
    • Install the unit on the wall in an upright position; avoid lying down or upside down. (See Unit Installation Steps on Page 4)
    • There are 2 installation methods: single point usage and multipoint usage. (Refer to Diagrammatic Views on Page 6, 7) Note: former option can lower the possibility of malfunction and extend the life span of unit.
    • Install cold water valve and a swing check valve in the supply pipe work to prevent back flow.
    • Link the shower head and the water heater with the hose provided.
    • For first time use after installation, please allow water to flow into water heater so that the water heater contains water before electricity is connected, at the same time, it can help to clean impurities from pipe line.
    • Install No Fuse Breaker (20A/30A/40A/50A) in accordance with amperage required for the model to prevent electrical overloads.
    • To comply with Electrical Regulation, it is highly recommended to install Super Guider’s leakage circuit breaker in switchboard or next to water heater.
    • Power cord entry points are on the top and on the side of the base brim of water heater unit, which needs to be cut off to extend out the cord.
    • Route the cords (4mm²/6mm²/10mm² standard cords according to model for safety purposes) into water heater and connect the earth cord to terminal “E”, neutral cord to terminal “N”, live cord to terminal to “L”. 
              NOTE: the water heater must be earthed.
    • Turn on electric supply at the isolating switch.

    Unit Installation Steps
    • Make sure it is flat on the wall surface that you want to install the water heater on. Install it using the install sticker and screws provided. Space for each side of the sticker must be at least 25cm.
