CAUTION
• The handle of TP Valve should be pulled out once per half year, to make sure that there is no jam of the valve.
• Please beware of burn, because of the high temperature of water.
Handle
Drainage pipe
• Do not pull on the handle of TP Valve. Do not dismantle the TP Valve.
• The drainage pipe should be well installed ,in order to avoid freezing up in cold weather.
• Do not block off the drainage pipe.
• It will cause explosion and injury, if do not comply with the above instruction.
• Installation of the One Way Valve: The spec of the One Way Valve thread in accessories is RC3/4”. It is used to prevent
backflow of water.
• Installation of the Strainer : The spec of the Strainer thread in accessories is RC3/4”. It is used to filtrate inlet water.
• After all the pipes installed turn on the cold water inlet and hot water outlet and start effusing the tank. When there is
water normally flowing out from water outlet, the tank is full. Turn off all valves of outlet pipes and check all pipes. If there is
any leakage, please repair it.
• If the inlet water pressure is less than 0.15 MPa, a pressure pump should be installed at the water inlet.
• For guarantee the long safety using age of tank at the condition of water supply hydraulic higher than 0.5MPa, a reducing
valve should be mounted at the water inlet pipe.
