* Safety information:

1.The water heater must connect with earthing secured; it’s forbidden dismantling the earthing device.

2.  It is forbidden to install and use the water heater invertedly .

3. The rated current of the power switch can not be less than the rated current of the water heater.

4.  The device must be filled with water before power on when use for the first time or discontinued for a long time.

5.  If the water in the device may be freezing, do not power on before confirm that the ice in the water heater has been thawy.

6.   Shut off the power and turn off the inlet valve when you don't use the water heater.

7.  If the power cord is damaged, it must be changed by the manufacturer or maintenance department or the professional person .

8.  Shut off the power when the water heater is blocked and clean the inlet filter and outlet shower.

9.  If  the pressure of  tap water exceed 0.6MPa, it should be installed a reducing valve  at the inlet.

10. When the water temperature is 15 ℃, the water resistivity should be not less than 1300 Ω * cm.

11.The outlet of the water heater should be connected with an inlet hose according with IEC61770.

* Installation Instruction:

1.Please note following items before installing the water heater:

Check the ammeter, wire sizes, fuse and the capacity of power switch carefully if they are qualified;

 

The water heater must be installed vertically ,it should not be flatwise.

 

For the position of the installation, please make sure that the power supply switch must be apart from the area of the showerhead insufflation.

2. Fix the panel.

Press the paper card of water heater on the wall and mark the screw holes by pencil, remove the card and drill the holes , then fix the panel by expansion screws on the wall.

3. Install the water heater

1)Fix the water heater to the 7 holes of the paper card and mark .

2)Drill the holes , and then install the water heater by expansion screws on the wall.

4. Install the inlet and outlet pipes

Please install a suitable control valve at the outlet of the water heater, then connect the inlet of the valve to the outinlet of the water heater, pleas put a filter at the inlet of the heater to the debris (if water pressure exceed 0.6MPa, please install a reducing valve at the inlet of the device.)

If the outlet pipe connected to the sprinkler directly, please connect the hosepipe of the sprinkler to the water heater outlet with the sealing ring.

Note: Do not force to connect the inlet and outlet pipe, so as to avoid damage to the water heater.

DR07A-3N180JDR07A-3N210JDR07A-3N240JMechanic type

1.  Close the external power supply switch, the power indicator light on.

2.  Switch on the inlet valve of the tap water, water flow out from the outlet.

3.  This  is mechanical type water heater ,  it use the mechanical gear knob for power regulation , switch clockwise to full power maximum  and counterclockwise to the minimum power( 2/3 rated power ).

4.  Users can choose the gears or control the water flow through the regulating valve to reach the  temperature you expect.

5.  Switch off the water valve when you are using the device, the water heater will stop working and heating.

6. Open the water valve, water heater will be working again, it do not need to adjust the operating buttons.

Safety protection function

1.When the outlet temperature exceed 75, the water heater will stop heating until the water temperature drop  to below 70. If dry heating happened, the protection device will switch off the power supply automatically. 

2.Over-pressure protection: If the pressure of inlet is too high, the inlet safety reducing valve start to work automatically, until the water pressure return normal. It is natural phenomena if water drip from the valve. 

Maintenance

To make sure the normal use for the hot water, please pay attention to maintain:

1.For there are many impurities in the tap water, they may deposit in the strainer when it use for a long time, it will lead to waterway blockage, affect the normal use of the water heater and damage it,  it is necessary to clean termly.

 

2.Regularly check the power cord, leakage protection switch are connected well and secured and the earthing is firm and reliable.

 

3.Cut off the power supply when you do not use the water heater.

 

4. Do not spray directly when clean the shell, it should switch off the power supply first and wipe gently by soft and wet cloths, then use the dry cloths. Please keep the shell to be dry and clean.

 

5. Descale:It shall be checked by authorized and qualified technicist once a year. Descaling check is necessary, especially for the local hard water exceeded 12 dH (German standard of water hardness).
