6. Pipeline ConnectionInstructions
(1) Installation requirements ofwater inlet pipes
Screw thread is 3/4" BSP F. The lifetime of pipes and pipe components cannot be shorter than the lifetime
of the appliance, and they should be able to withstand high temperature of 80℃ , so as to avoiddamage.
(2) Installation requirements of safety valve connection pipes
Screw thread of inlet side is 3/4'' BSP M and the outlet side is 3/4'' BSP F. Make sure the water can flow
out of the safety valve and the drainage outlet should be installed straight downwards. After finishing
installation, please make sure that drainage hose connected to the safety valve's drainage outlet should
be maintain downward and stay open to the frost - free environment.
(3) The pressure ranges of the water tank is 0.15MPa~1.0MPa. If the water inlet pressure is always lower
than 0.15MPa and in order to get higher water flow to meet water consumption requirement, you need
to add a booster pump at the water inlet so as to keep the water pressure no lower than 0.15MPa; if the
water inlet pressure is always higher than 0.5MPa, you need to add a reducing valve of 0.5MPa at water
inlet pipe so as to make su re the safety use of the tank.
7. Electrical Wiring
● This appliance should use specified power cord, which should be required as the below table. The
voltage of power should also be suitable with the rated voltage requirement.
● The power supply circuit should have ground wire, which should be connected with outside ground
effectively.
● Wiring connection must be done by professional technical person and operate strictly according to
the electrical diagram.
● Set up earth leakage protection according to the relevant national electrical equipment standards.
● Install all
pole circuit breaker with minimum 3 mm contact separation.
-
●Double check the electrical circuit before connecting to the power supply.
●Do not disconnect or disassemble the ground wire, or use broken cables and switches under any
circumstances. If you find out any breakage, the power cord must be replaced as soon as possible.
