Pipeline Connection Explanation
Installation of the water inlet or outlet pipes: the
specifications of the water inlet or outlet thread is
RC3/4” (internal thread).
Pipes must be heat-resistant and durable.
PIPELINE CONNECTION
5.
•
Installation of the pipe for PT valve: the specifications
of the valve conncting 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.
•
A safety valve should be installed at the water
inlet of the Unit.
Arrange water pipes and connected fittings as it is
shown in Fig. 5-1.
In case of installation in a place where outside
temperature is below freezing point, insulation must
be provided for all hydraulic components.
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.
If you do not comply with the above
instructions, explosions and injuries
may occur.

•
Installation of the One Way Valve: the specifications
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 specifications
of the Y-shaped filter thread in accessories is RC3/4”.
It is used to filtrate inlet water.
•
After installation of all pipes, 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 pressure is less than 0.15MPa, a pressure
pump should be installed at the water inlet.
For guaranteeing the long safety using age of tank
at the condition of water supply higher than 0.65MPa,
a reducing valve should be mounted at the water
inlet pipe.
•
Since during the drainage, water leakages may
take place, it is recommended to use a water
collector, as it is shown in Fig. 5-2.
