authorized maintenance
center.
If an exception persists, the
air source water heater may
be damaged, which may
even cause an electric shock
hazard or cause a fire.
Do not operate the water
heater with wet hand.
Otherwise, an electric shock
hazard may be caused.
Before installation,
check whether the
voltage of the local
power grid
accords with the
voltage on nameplate
of the unit, and
capacity of the power
supply, power cord or
socket is suitable for
input power of this unit.
Dedicated lines must be
used for the power supply
to prevent a fire.
Do not use multipurpose
sockets or mobile wiring
boards to connect wires.
Otherwise, overheating or
even a fire may be caused.
Pull out the power plug
and drain the main unit
and water tank when water
heater is not in use for a long
time to prevent cracking
caused by cold weather.
Do not
damage wires or use
undesignated wires.
Otherwise,
overheating or a fire
may be caused.
Before cleaning, please
cut off the power supply.
Otherwise, an electric
shock hazard may be
caused.
Use dedicated circuits with
a leakage circuit breaker
protection for the power
supply and ensure sufficient
capacity.
Otherwise, overheating, a
fire, or an electric shock
hazard may be caused.
Do not change the
power cord or
socket without any
consent. Wiring tasks
must be completed by
qualified electricians.
Ensure proper

unit at a well-ventilated
place. Do not block the air
inlet or outlet of the main unit.
Otherwise, energy efficiency
may be reduced, and
shutdown or even a fire may
be caused.
Keep chemical
sprays, gas tanks at

(about one month) basis to
check whether it is blocked.
Perform sewage disposal
by following the guide on a
regular (about once a year)
basis.
It is normal that the safety
check valve drips.
The pressure relief
opening of the safety
check valve must be
connected to one end
of a securely fixed
guide hose, and the
other end is
connected to the floor
drain. Ensure that the
guide hose is not
twisted or folded.
The installation direction
of the safety check valve
must be correct; that is, the
direction indicated by the
arrow on the safety check
valve must be the same as
the flow direction of
cold water.
You are advised to install
the filter horizontally after the
main shutoff valve of the
user's water pipe. Ensure
that the direction indicated by
the arrow on the filter must
be the same as the water
flow. If impurities inside
the waterway need to be
cleared, open the end cap of
the filter.
When the filter is
installed vertically, the
direction indicated by
the arrow must not be
upward and the end
cap must be placed
slantwise downwards.
The fuse model and
