Air outlet could be connected to the air duct to bring fresh cool air into the rooms.
If this measure is carried out, a reversing valve should be installed in the air duct to make the
cool air blows to outdoors in winter.
Ventilation
The unit can extract the indoor air during its running to achieve the ventilation, which can purify
the indoor air. In the low ambient temperature, it can also improve the efficiency of unit
performance.
Because the supplied hot water absorbs heat from the surrounding air and release the heat
at heat exchanger side. Once ambient temperature goes down, the heating capacity may
decrease accordingly.
3 minutes protection
When stopping after running, the user immediately starts the unit or turns on manual
switch, the unit will not run within 3 minutes. This phenomenon is to protect compressor by the
main controller.
In heating mode, if the unit freezes, the machine will automatically defrost to promote
heating capacity.(2 to 10 minutes) Under defrosting process, the fan motor of the unit will stop
running and compressor continue running.

The unit only can use tap water .Please do not use the water from any lake, river or
underground water which are not filtrated or treated.
If power is cut during machine running, the unit will stop immediately.
If the unit is mis-works because of thunder, wireless of motor car, power net fluctuation, please
turn off the power switch by hand. After the unit restarts, the user can re-press the running/stop
button.

The unit must be connected with power net through current leakage protector.
When water temperature reaches 75°C, the electric heater will be off(automatic recovery). When
water temperature reaches 85°C, the fuse of electric heater will fuse (un-recovery)
In the water system will be installed the P&T valve. When the tank pressure reach
0.7MPa,or the temperature reach 99°C, the P&T valve to open sluice.
ATTENTION
P&T valve is a necessary component of the unit.
Do not hold the handle of the P&T valve;
Do not block the drain outlet;
Lead the drain pipe to an open drain channel.
Please Obey the above instructions to avoid any possible injury or unexpected accident. Do
not use stainless steel fittings to connect directly with other metals to prevent galvanic
corrosion.
