Hot water pipe should preferably not be too long in order to prevent heat loss. Note: Make sure that the water heater is securely attached to the hook before letting it go; otherwise it may drop and cause injury or property damage. Installation Precautions When installing the water heater, certain space should be reserved (not less than 250mm from the top and bottom and not less than 700 mm from the front and the sides), for ease of subsequent maintenance and repair. If the water heater was to be built into clip boards, the bottom section of the clip board should be movable for ease of removal of plastic cover during maintenance.

Hot water pipe Sprinkler head Cold water inlet :Direction of cold water :Direction of hot water Installing safety valve Install the safety valve which has a rated pressure of 0.80MPa (its connection is G1/2) into the water inlet pipe with the arrow on the safety valve pointing at the water heater. When the water heater is heated by electricity, a small amount of water will ow from the safety valve's pressure-relief hole due to the expansion of water in the heater. This is normal. The pressure-relief hole should be connected to the atmosphere and free from blockage at all times. Installation method for safety valve's drainage pipe: Attach an end of the water drainage pipe onto the pressure-relief hole on the safety valve. You Small handle for safety valve Pressure-relief hole (connected to water drainage pipe) Make sure the pressure on the water inlet is not less than 0.05MPa, and not more than 0.75MPa. The water heater should be installed indoors in a place where the ambient temperature is above 0oC. The pipes should be closely laid out. The hot water outlet should not be too far away from the point of usage. If the distance exceeds 8 meters, the hot water pipe should have insulation protection, in order to prevent heat loss. The wall on which the water heater should be strong such as it is able to withstand fourth the weight of the water heater when lled with water. If the wall was not weight-bearing wall or made of hollow bricks, adequate protective measures such as addition of support and high-strength wall screw with back panel should be adopted. The water heater should be installed in places such as it is easy to use and maintain and with oor drain, in order that it will not cause damage to nearby facilities or those in the lower levels during a leakage of the water tank or water pipe. It should not be installed over toilet bowls, bathtub, wash basin or door frame in order that users do not feel oppressed or insecure. Power socket for the water heater should be installed in dry places which do not easily come into contact with Do not reverse the installation for the water inlet and outlet. The safety valve should be installed in the designated position and should not be moved without permission. The safety valve's pressure-relief hole should be connected to the atmosphere and free from blockage at all times. Use pen multimeter to check whether the live line and neutral line are reverse. Turn on power supply only when you have ensured that the heater is lled with water and that there is no water leakage. The power supply should also conform with requirements. may cut the water drainage pipe to make it shorter, or extend it depending on the situation. Connect to the other end of the water drainage pipe to the lower water outlet. This will prevent (Fig. 3) Safety reminder: In order to prevent accidents, please use our company's accessories during installation. Do not replace them on your own or use substitutes. Please make sure to contact our Maintenance Department if the pipes
