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 downwards and
stay open to the frost-free environment.
(3) The pressure ranges of the water tank is 0.15MPa~0.8MPa. 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 0.8MPa, you need to add a reducing valve of
0.8MPa at water inlet pipe so as to make sure the safety use of the tank.
7. Electrical Wiring
● This appliance should use specified power cord, which should be required as below. The voltage of
power should 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.
