E. Maintenance and service
Examination before trial run
1. Check the water tank is filled with water, and open the water outlet tap till water flow out.
2. Check the water pressure is normal (0.15Mpa~0.7Mpa).
3. Check the air inlet or outlet is well connected; and the air outlet pipe heat insulation is completed.
4. Check the power supply voltage is normal, whether according with the nameplate
requirement. (Range ± 10%).
5. Check whether the equipped parts are screwed /locked well.
6. Check whether the wirings are according with the Circuit diagram, and the earthwire
is connected.
7. Check whether the wind inlet and outlet has been cleaned up and no obstacle.
8. Check whether the condensate drain pipe is connected well and no blockage.
9. After power-ON, check the control panel display is normal.
Trial running
1. After the machine starts, to hear and determine whether there is abnormal sound or collision
during operation, if there is abnormal sound, stop the unit immediately and check for it until
there is no abnormal sound to continue operation.
2. For the first time power on, the compressor will have 3 minutes delay protection function.
3. Observe whether the drainage of condensate water is smooth, prevent the chassis stagnant or
spill water.
4. For the first time discharge hot water or start the units after a long time closure, the water tap
of outlet pipe may flow muddy water, this is a normal phenomenon, and continue to drain for a
period of time can be cleared.
5. After stop operation for a long time, there may have condensation water hereabout the air
outlet or pipe (especial in humidity weather), this is a normal phenomenon, use a dry washcloth to
clean it or by air dry.
6. The advance setting parameters of the operation panel has been set at the factory, users no
need to reset it, the maintenance person should be carefully set if needed.
Maintenance and service
1. After carry and move the unit by the first time installation, and connects the water pipes and
filled the tank with water. The machine should be rest for 1-2 hours before start trial running.
2. The water heater inlet filter needs to be cleaned once per 3 months. At the same time, per
half year we suggest draining all the storage water and repeatedly wash for 2-3 times to
remove the dirt and sediment.
3. To keep the unit in good heating performance, suggest cleaning the Air inlet /outlet filter net
per month, or using high pressure air tube to clean the Heat exchanger. Be careful not to
damage the copper tube.
4. Clean the Electric Heater per 6 months. (When clean the Electric Heater or Heat Exchanger
must cut off power supply.)
5. Change the Anode (Magnesium rod) per 6 months for better anticorrosion and antiscale.
According to different water quality, change the Anode rod when it's expended.
6. When clean the Tank, Electric Heater, Heat Exchanger or Anode rod must cut off power
supply.
7. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a
similarly qualified person.
8. Special statement: for what does not in accordance with the requirements of above
maintenance and service work lead to the failure problem, does not apply to our warranty
scope.
