the power is restored, the wired controller sends power-on/power-off signals to
the water heater according to the status memorized before the power is cut off. This
ensures that the unit can run according to the original status after the power is
restored.
15 Notes on Winter Use
(1) Temperatures in winter are low. If the unit is not used for a long time, before
starting the unit, connect it with electricity for at least 8 hours.
(2) Outdoor temperatures in Winter are relatively low, do not disconnect the unit
from electricity if it needs to be shut down for a short time. Otherwise, the automatic
freeze-proof protection function will fail.
At low ambient temperatures, the automatic
freeze-proof protection function enables the unit to heat the water before water
temperature approaches the freezing point. When the water temperature rises to a
safe temperature, the function is disabled.
However, this function does not apply to
the water inlet and outlet pipes of the water tank. If the water tank is inevitably
installed outdoors, reduce the outdoor part of pipes including the refrigerant
connecting pip and water inlet and outlet pips of the water tank. Otherwise, the heat
loss is large, power consumption increases, and the water system is vulnerable to
freezing.
In addition, pay attention to thermal insulation of special positions such as
valve joints and pipe bends. Otherwise, these positions are vulnerable to freezing.
(3) If the unit is not used for a long time, drain the water in the water tank and
the pipes by following drain operations. Otherwise, the water system may be frozen
and damaged.
Use the unit after the water is drained and then the water tank is full
filled with water.
Tips:
If it is inconvenient or dangerous to perform the preceding operations,
directly contact your local dealer or authorized service center of C
&H
, and
GREE will dispatch professional personnel to provide inspection, drainage, water
replenishment, commissioning, cleaning, and maintenance services.
