valve at the water outlet of the water tank. They must be installed if the water tank is far away (the hot
water pipe is longer than 20 m) from the location for water use or all locations for water use are lower
than the cold water inlet of the water tank.
(3) Installing the safety valve
Use a PPR pip to connect the safety valve delivered with the unit to the water inlet of the water tank
(note: the direction indicated by "" should point to the water tank). The other end of the safety valve is
connected to the tap water for water replenishment. To ensure safe use, please strictly follow the
installation order shown in Figure 5-2. Safety valve must install diversion tube and be reliably fixed to
prevent falling off; lead the drainage hose to floor drain downward naturally and properly without bending
or any twine. After that, the surplus hose must be cut to avoid water in drainage hose getting frozen due
to blocking of drainage or low temperature.
To avoid any inconveniences or property losses due to water leakage or safety valve discharging
water which is resulted from improper connection of water pipe, water tank and safety valve shall not be
installed inside the room or balcony which is without discharge floor drain.
(a) Installation method 1(inlet cold water pressure is between 0.1MPa and 0.5MPa)
(b) Installation method 2(inlet cold water pressure is less than 0.1MPa)
(c)
(4) Installing the drainage pipe
As shown in Figure 3-4, remove the plug of the three-way valve. Then, use a drainage pipe to
connect the three-way valve to the floor drain, and ensure that the drainage pipe and the joint of the floor
drain are lower than the bottom of the water tank. Otherwise, the water cannot be drained. In addition,
the cut-off valve must be installed in the position at which the user can conveniently operate it.
