-
be left open to the atmosphere.
- The one-way safety valve is to be operated regularly to remove lime deposits and to verify that it
is not blocked. Please beware of burn, because of the high temperature of water.
The tank water can be drained through the drainage hole on the bottom of the tank.

-
there is water normally following out from water outlet, the tank is full. Turn off all valves and
check all pipes. If any leakage, please repair.
If the inlet water pressure is less than 0.15MPa, a pressure pump should be installed at the
-
water inlet. For ensure the long safety using age of tank at the condition of water supply
hydraulic higher than 0.7MPa, a reducing valve should be mounted at the water inlet pipe.
Filters are needed in the air inlet. If the unit is connected with ducts, filter in there must be put
-
forward to the air inlet of duct.
- To fluently drain condensate water from evaporator, please install the unit at the horizontal floor.
Otherwise, please make sure the drain vent is at the lowest place. Recommending the
