ATTENTION:
-
The one-way safety valve must be installed. If not, it could cause damage to the unit, or even
hurt people. The set point of this safety valve is 0.7MPa. For the installation place please refer
to the pipeline connection sketch.
-
The discharge pipe connected to the one-way safety valve is to be installed in
a continuously downward direction and in a frost-free environment.
-
The water may drip from the discharge pipe of the one-way safety valve and that this pipe
must 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 be ware of burn, because of the high temperature of
-
The tank water can be drained through the drainage hole on the bottom of the tank.
-
After all the pipes installed, open stop valves of the cold-water inlet and hot water outlet to
fill the tank.
-
When there is water flowing out from water outlet pipe which means the tank is full. If any
leakage, please repair.
-
If the inlet water pressure is less than 0.15MPa, a pressure pup should be installed at the
water inlet. If water pressure from supply is greater than 0.65 MPa, the pressure-reducing
valve is necessary to be installed at the water inlet pipe.
-
Filters are needed in the air duct inlet side. If the unit is connected with ducts, filter must
be installed to the air inlet side of the duct.
-
To fluently drain condensate water from evaporator, please install the unit at the horizontal
level
-
Otherwise, please make sure the drainage vent is at the lowest place. Recommending the
inclination angle of unit to be ground should no more than 2degree.
