exposed to the vapor. The water may be out-flowed from the pressure relief 
valve,  so  the  outlet  pipe  must  be  opened  wide  towards  the  air.  In  order  to 
drain away the water inside the tank (inner container), open up the pressure 
relief valve. Twist off the thread screw of the pressure relief valve, and lift the 
drain  handle  upwards  (see  picture  1).  The  drainage  pipe  that  connected  to 
the  pressure  relief  hole  must  be  kept  sloping  downwards  and  placed  in  a 
frost-free  environment.  The  water  may  drip  from  the  discharge  pipe  of  the 
pressure  relief  valve;  therefore,  this  pipe  must  be  left  open  to  the  air 
(atmosphere). 

 

During the heating process, there may be drops of water  dripping from the 
pressure relief hole of the pressure relief valve, and this is a normal case. The 
pressure relief hole shall not be blocked under any circumstances; otherwise, 
the water heater may get damaged or even resulting on accidents. If there is 
a  large  amount  of  water  leak,  please  contact 

MODENA

  Customer  Care  for 

repair. 

 

The pressure relief valve needs to be checked and cleaned regularly, to make 
sure it will not be blocked. 

 

Since the water temperature inside the water heater can reach up to 75 °C, 
the hot water must not be exposed to human bodies when it is initially used. 
Adjust  the  water  temperature  suitably  to  the  endurance  of  human  skin  to 
avoid scalding. 

 

If  any  parts  and  components  of  this  water  heater  are  damaged  please 
contact 

MODENA

 Customer Care for repair.
