Caution:
When install the main unit, please set a drain valve at the drain orifice of the unit by self.
Pipeline Connection Explanation
Installation of the water inlet or outlet pipes: The spec of the water inlet or outlet thread is
RC3/4” (internal thread). Pipes must be heat-resistant and durable.
Installation of the pipe for PT valve: The specification of the valve connecting thread is RC3/4”
(internal thread). After installation, it must be confirmed that the drainpipe outlet is exposed in
the air. When flexible drainpipe is jointed to the pressure relief orifice of this valve, it must be
confirmed that the flexible drainpipe is downwards vertically and exposed in the air.
NOTE:
A safety valve should be installed at the water inlet of the unit.
The handle of PT 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.
The drainage pipe should be well installed ,in order to avoid
freezing up in cold weather.
Do not press the handle of PT Valve,
Do not dismantle the PT Valve,
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 specification of the one way valve thread in accessories
is RC3/4”. It is used to prevent backflow of water.
Installation of the Y-shaped filter: The spec of the Y-shaped filter thread in accessories is
RC3/4”. It is used to filtrate inlet water.
After all the pipes installed turn on the cool 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 and check all pipes. If there is any leakage, please repair.
If the inlet water pressure is less than 0.15MPa, 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 0.65MPa, a reducing valve should be mounted at the water inlet pipe.
