(3) Installation requirements of Y-filter
Screw threads are G1/2''. The direction of installation should be consistent with the water inlet
direction, while the drain outlet of the filter should be downward.
(4) The water tank's supply water pressure ranges 0.15MPa ~ 0.5MPa. 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 sure the safety use
of the tank.
7. Electrical Wiring
ATTENTION
●
The 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.
●
Use all-pole disconnection device which has at least 3 mm contact separation when connecting
the power.
●
Double check the electrical circuit before connecting to the power supply.
●
Don't disconnect or disassemble the ground wire, nor use broken cables and switches under
any circumstances. If you find out any breakage, the power cord must be replaced as soon as
possible.

Note:
When the air source heat pump water heater is running, if there is no operation or
malfunction for 35 seconds, the display only displays the current water temperature, while it
displays no value in stand-by status. When the water temperature indicator flashes continuously, it
means the appliance's disinfection function is on.
