Condensate Water Pipe Connection
Ensure the condensate water pipe, connected with condensate water outlet, is unobstructed and toward floor
drain without bended. (Figure 4)
Control box connection
When installing the control box on the wall, if the threading groove or wire
clamper is installed on the surface, please put the control wire directly into the
threading groove or wire clamper and then set the control box on the fixed
plate (standard configuration) which is preinstalled on the wall. If the
threading groove is pre-buried in the wall, firstly open the cover of the control
box then remove the 4 screws from the control box. And open the control box
and tale out the control wire from it, pulling out it from the display board.
And then let the control wire pass through the wire pipe (please note not to
damage the two-core plug and the wire), inserting the two-core plug on the
display board. Next send the display board back to the control box and close
the lid of control box with tightened screw. Finally fix the whole control box
on the 86 box which is preinstalled on the wall.
Power Connection
z
All the wires must come with water heater and be installed or replaced by authorized dealer, instead of
being installed by user’s own.
z
It must be reliable grounded as showed in Figure 6 to avoid electric shocking. Make the ground wire
connect the longer wire core than others and be the final one to be tightened under external force.
z
Ensure the wires be fixed well with the plates after finish connecting.
Water Filling
After all the pipes connection, open the outlet valve of the heater and then the
inlet valve. Fill heater tank with water until water flowing smoothly through
outlet pipe, which means the tank is full of water. Shut off the outlet valve,
and check if there is any leakage at joints. If yes, evacuate the tank, fix joints
and repeat until no leakage appears.
