First, unplug the heater. Remove the cover plate to access the thermal switch. Press the manual reset button at its center. If it does not click, wait for it to cool down. If the problem persists, contact a professional. Do not disassemble the switch yourself.

What maintenance is required regularly?

Regularly check the magnesium anode for decomposition and replace if needed. Clean the internal tank and heating element to remove deposits. Frequency depends on water hardness. Contact a service center for cleaning.

Can I use an extension cord?

No, extension cords are not allowed. The plug and socket must be in good contact. Check periodically: after 30 minutes of use, unplug and feel if the plug is hot (over 50°C); if so, replace the socket.

Is the CTRC-15-M energy efficient?

Yes, it has an energy efficiency class A with a water heating efficiency of 35.3%. Annual electricity consumption is 522 kWh for the declared load profile XXS.

What to do if no hot water comes out?

Check if the water supply is on and the inlet valve is open. If the hydraulic pressure is too low, wait for it to increase. If the indicator light is off, the thermal switch may have tripped; reset it as described. If the problem continues, call a professional.

1. CAUTIONS

Before installing this water heater, check and confirm that the earthing on the supply socket is reliably grounded. Otherwise, the electrical water heater can not be installed and used. Do not use extension boards. Incorrect installation and use of this electrical water heater may result in serious injuries and loss of property.

Special Cautions

• The supply socket must be earthed reliably. The rated current of the socket shall not be lower than 10A. The socket and plug shall be kept dry to prevent electrical leakage. Inspect frequently whether the plugs contact well with the socket. Inspect method is as follows: insert the power supply plug into socket, after using for half an hour, shut down the unit and pull the plug out, and inspect the plug whether it scalds hand. If it scalds (over 50°C), please change another well-contacted socket to avoid the plug being damaged, fire or other personnel accidents result from bad-contacting.
• The installation height of the supply socket shall not be lower than 1.8m.
• The wall in which the electrical water heater is installed shall be able to bear the load more than two times of the heater filled fully with water without distortion and cracks. Otherwise, other strengthening measures shall be adopted.
• The pressure relief valve attached with the heater must be installed at the cold water inlet of this heater(see Fig.1), and make sure it is not exposed in the foggy. The water may be outflowed from pressure relief valve, so the outflow pipe must open wide in the air; The pressure relief valve need to be checked and cleaned regularly, so as to make sure it will not be blocked.

(Fig.1)

- When using the heater for the first time(or the first use after maintenance), the heater can not be switched on until it has been filled fully with water. When filling the water, at least one of the outlet valves at the outlet of the heater must be opened to exhaust the air. This valve can be closed after the heater has been filled fully with water.

- The water heater is not intended for use by persons(including children)with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instructions concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the heater.

- During heating, there may be drops of water dripping from the pressure release hole of the multifunction valves. This is a normal phenomenon. If there is a large amount of water leak, please contact customer care center for repair. This pressure release hole shall, under no circumstances, be blocked; otherwise, the heater may be damaged, even resulting in accidents.

- The drainage pipe connected to the pressure release hole must be kept sloping downwards.

- Since the water temperature inside the 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 to a suitable temperature to avoid scalding.

- Unscrew the thread screw on the multifunction safety valve, and lift the drain handle upwards. (See Fig.1) to drain the water from the inner tank.

- If the flexible power supply cord is damaged, the special supply cord provided by the manufacturer must be selected, and replaced by the professional maintenance personnel.

- If any parts and components of this electrical water heater are damaged please contact customer care center for repair.

- This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.

- Children should be supervised to ensure that they do not play with the appliance.

3. UNIT INSTALLATION

3.1 Installation Instruction

① This electrical water heater shall be installed on a solid wall. If the strength of the wall cannot bear the load equal to two times of the total weight of the heater filled fully with water, it is then necessary to install a special support.

Incase of hollow bricks wall, ensure to fill it with cement concrete completely.

② After selecting a proper location, determine the positons of the two install holes used for expansion bolts with hook (200mm), Make two holes in the wall with the corresponding depth by using a chopping bit with the size matching the expansion bolts attached with the machine, insert the screws, make the hook upwards, tighten the nuts to fix firmly, and then hang the electrical water heater on it (see Fig.2).

(Fig.2)

③ Install the supply socket in the wall. The requirements for the socket are as follows: 250V/10A, single phase, three electrodes. It is recommended to placed the socket on the right above the heater. The height of the socket to the ground shall not be less than 1.8m (see Fig.3). If there is fault on power cable, it should be replaced by the manufacturers, agencies or qualified person who is able to do this so as to ensure the safety.

④ If the bathroom is too small, the heater can be installed at another place without sun-scorched and rain-drenched. However, in order to reduce the pipeline heat losses, the installation position of the heater shall be closed to the location shall be as near as possible to the heater.

3.2 Pipelines Connection

① The dimension of each pipe part is G1/2"; The massive pressure of inlet should use Pa as the unit; The minimum pressure of inlet should use Pa as the unit.
② Connection of pressure relief valve with the heater on the inlet of the water heater.
③ In order to avoid leakage when connecting the pipelines, the rubber seal gaskets provided with the heater must be added at the end of the threads to ensure leak proof joints (see Fig.4).

(Fig.4)

④ If the users want to realize a multi-way supply system, refer to the method shown in fig.5 for connection of the pipelines.

(Fig.5)

NOTE

Please be sure to use the accessories provided by our company to install this electric water heater. This electric water heater can not be hung on the support until it has been confirmed to be firm and reliable. Otherwise, the electric water heater may drop off from the wall, resulting in damage of the heater, even serious accidents of injury. When determining the locations of the bolt holes, it shall be ensured that there is a clearance not less than 0.2m on the right side of the electric heater, to convenient the maintenance of the heater, if necessary.

4. METHODS OF USING

- First, open any one of the outlet valves at the outlet of the water heater, then, open the inlet valve. The water heater gets filled with water. When water flows out of the outlet pipe it implies that the heater has been filled fully with water, and the outlet valve can be closed.

NOTE

During normal operation, the inlet valve shall be always kept open.

Insert the supply plug into the socket.

- If the indicator lights up, the thermostat will automatically control the temperature. When the water temperature inside the heater has reached the set temperature, it will switch off automatically, when the water temperature falls below the set point the heater will be turned on automatically to restore the heating.

(Fig.6)

① Rotate the knob according to the marking on the knob to increase or decrease the setting temperature.
② In a power-on state, the machine is heating when the indicator light is blue. The indicator light goes out when the heating process is finished, in the insulating state.

Do cut off power supply before maintenance, to avoid danger like electric shock.

• Check the power plug and outlet as often as possible. Secure electrical contact and also proper grounding must be provided. The plug and outlet must not heat excessively.
• If the heater is not used for a long time, especially in regions with low air temperature(below 0 °C), it is necessary to drain water from the heater to prevent damage of the water heater, due to water freezing in the internal tank.(Refer Cautions in this manual for the method to drain away the water from the inner container).
• To ensure long reliable water heater operation, it is recommended to regularly clean the internal tank and remove deposits on the electric heating element of the water heater, as well as check condition (fully decomposed or not) of the magnesium anode and, if necessary, replace it with a new one in case of full decomposition. Tank cleaning frequency depends on hardness of water located in this territory. Cleaning must be performed by special maintenance services. You can ask the seller for address of the nearest service center.

• The water heater is equipped with a thermal switch, which cuts off power supply of the heating element upon water overheating or its absence in the water heater. If the water heater is connected to the mains, but water is not heated and the indicator doesn't light up, then the thermal switch was switched off or not switched on. To reset the water heater to the operating condition, it is necessary to:

• De-energize the water heater, remove the plate of the side/lower cover.

• Press the button, located at the center of the thermal switch, see Fig.7;
• If the button is not pressed and there is no clicking, then you should wait until the thermal switch cools down to the initial temperature.
