Installation

Installation location
Do not install this water heater in a place where freezing may occur. The water heater should be installed as close as possible to the hot water point with the highest frequency of use. There should be enough clearance around the water heater so that the entire unit can be removed for repair or replacement if necessary. The electrical junction box and T&P relief valve should be oriented for easy maintenance, and the nameplate should be easy to read. The water heater should be installed on the floor to ensure that it is placed vertically and avoid tilting. The building must be able to withstand the total weight of the water heater after being filled with water without severe vibration.

• The water heater should be placed on a refractory base with a height of not less than 50mm, and there should be a high temperature-resistant floor drain with unobstructed drainage near the base to prevent damage to other facilities in case the water heater or pipeline leaks.
• The installation location should be well-ventilated, no obstacles that hinder the wind in and out, and should not be exposed to rain and direct sunlight.
• The water heater should be installed at location where its running noise and exhaust will not affect the neighbors.
• Make sure there is no leakage of flammable and corrosive gas at the installation location; no oily smoke and dust; no or only small fluctuations of power supply voltage.

Installation Clearance

Installation Precautions
Wiring work must be done by a qualified electrician and must meet electrical safety requirements. When the user needs to install and move, please contact the company’s after-sales service center for professional help. DO NOT install and shift it by yourself. Otherwise, the company will not be responsible for any damage and failure caused and warranty of water heater will be void.

• Warning: If the water heater is installed on the roof of building that is vulnerable to lightning strikes, the water heater must be protected by lightning protection facilities!
• Note: After the machine is in place, be sure to let the water heater stand for more than 30 minutes before turning on the power!
• Note: Please transport the water heater according to the state when it leaves the factory. Do not move the water heater at an angle of more than 30°, let alone place the machine vertically, and do not disassemble or assemble it yourself!

Pipe Connection

Pipe connection diagram

Connection Instruction

• Material Requirements
  Because the water heater and its piping system will bear pressure from tap water, all water-side pipes must be made of temperature-resistant, pressure- resistant, and corrosion-resistant metal or new-type plastic material. Pressure resistance performance of the pipes must not be lower than the relief pressure of the T&P valve, while the temperature resistance must not be lower than 99°C.

  • Cold/Hot water pipe connection
  • Connection size: Rp 3/4″
    Note:
    The water heater has a hot water pipe for the outlet connector and a joint bushing on the inlet connector. These devices are installed when the water heater leaves the factory and must not be removed or damaged during installation. When the threaded joint is screwed in, these devices will naturally be installed to the correct depth.

• Pipeline Size
  To ensure the best performance, the pipe size should be selected according to the specific installation needs. The following are the recommended pipe sizes.

  • Hot water pipe: Main pipe – Rp 3/4″ (20mm)
  • Cold water pipe: The size of the cold water pipe should be the same or larger than the size of the hot water pipe used.

• Cold water connection

  • The cold-water inlet is at the lower part of the water heater and should be directly connected with tap water. As shown in the figure, first connect a shut-off valve, then connect a non-return valve on the side close to the heater, and finally connect a union.
  • If supply water pressure exceeds the rated max. pressure (680 kPa) as stipulated in the label, a pressure limiting valve shall be connected after the non-return valve. If supply water quality does not meet the specific water quality requirements, an expansion control valve shall be used.

• Hot water connection

  • The hot water supplied by the water heater has a relatively high temperature and cannot be used directly for washing. It must be mixed with cold water. Therefore, the cold and hot water mixing valve should be installed at the hot water use point.
  • If the hot water outlet of the water heater is too far away from the hot water use point (more than 12 meters), it is recommended that the hot water pipe be insulated with heat-insulating materials to reduce the waste of hot water and electricity.

• Water supplied by tank

  • If cold water is supplied by a tank on the top floor, be noted that the cold water connection should meet the following requirements:
  • The tank shall be at least 1m higher than the highest hot water outlet. If the distance between the bottom of the domestic tank and the highest hot water outlet is less than 5 meters, precaution should be taken into consideration to avoid air locks in the hot water pipe. The shut-off valve in the cold water pipeline shall be changed to a gate valve, which shall be fully open to ensure the full flow of the cold water inlet.

Warning:
Regardless of the water supply method, the non-return valve on the cold-water inlet pipe must be installed correctly, otherwise, the water heater or its parts might be damaged.

• Condensation drainpipe connection
  The water heater is equipped with a condensation drain hose, one end of which is connected to the condensation drain and another end to the floor drain. To keep the water pipe drainage unobstructed, there should be no bends or distortion.

• Installation of T &P Relief Valve

• The temperature and pressure relief (TPR) valve acts as a safety device, which can keep system pressure at a safe level by discharging hot water to reduce pressure and lower down system temperature when detecting system pressure exceeds the rated value (850 kPa). If the water temperature is heated up to 93°C, the temperature sensing device will trigger the TPR valve for hot water discharging and cold water will be entered to cool down the system and reduce pressure. The discharge pipe connected to the relief valve should be installed in a frost-free environment in a continuous downward manner, making sure water can flow out freely; and the discharge pipe should be kept open to the atmosphere. Specification of the TPR valve is 3/4″ × 125PSI (850 kPa).

  • Take out the T&P relief valve, and make sure that the probe is not bent. Inspect the operation lever and the flexibility of the handle.
  • Wrap the thread with PTFE, do not let the PTFE go beyond the end of the thread; screw the T&P valve into the installation hole, and make sure the valve drain outlet is facing down.
  • Connect a DN20 drainpipe from the drain outlet of the TPR valve to the floor trap. It is strictly forbidden to install a valve on the drainpipe, and the total length of the pipe shall not exceed 9 meters while the right-angle bend shall not exceed 3.
  • If the drainpipe is too long, to facilitate disassembly, a live connection can be connected near the outlet of the TPR valve.

Warning:
Drainpipe of the T&P relief valve shall be installed in a forest-free environment and kept inclined downwards. The outlet of the drainpipe should not be blocked at any time, and it should be kept in contact with the atmosphere, and make sure the discharged hot water will not endanger people’s safety or cause property damage.

Wiring connection

The power supply for the water heater is a single-phase AC with rated voltage 220V ~50Hz. The wiring diagram is as below:

Precautions

• A specific power supply must be provided for the water heater, whose maximum voltage fluctuation shall be within 90% and 110% of the rated voltage.
• Wiring works must be performed by those skilled in this art and must comply with electric safety requirements.
• Grounding measures must be reliable, otherwise, fire accidents or electric shocks may occur.
• Power and signal cables must be well and properly arranged. No interference between strong and weak power. Cables shall not contact with the connection tube and valve.

Hot Water Usage

• Under normal circumstances, the cold-water inlet shut-off valve should always be open, and cold water will be automatically replenished when hot water is discharged.
• During the heating process of the water heater, it is normal for the T&P relief valve to discharge a small amount of hot water
• In the event of a power failure, the stored hot water can still be used.
• When the water supply is cut off, it is recommended to close the cold water shut-off valve of the water heater to prevent water from flowing back and emptying the tank due to failure of the non-return valve, which can be reopened when the water supply is restored.

Warning:
To prevent scald and burns, never let children use the hot water faucet or take a bath by themselves; never leave children or disabled people alone in the bathtub or under the shower head without care.

Turn off the water heater
If the water heater needs to be turned off for maintenance or long time shutoff, please follow the instructions below:

• Cut off the power supply of the water heater.
• Turn off cold water and hot water shut off the valve.

Note:
If you do not need to use the water heater in winter in cold areas, please empty the water in the tank in case of freezing damage.

Water quality

The water heater is applicable for water quality in most urban areas. Please refer to the detailed water quality requirement in Nation Standard CJ/T 206-2005 “Water quality standards for urban areas”. Poor water quality will have a detrimental effect on the water heater and its operation and /or life expectancy. If you are unsure of your water quality, information can be obtained from your local water supply authority.
This water heater can be used in areas where the total dissolved solid content (TDS) in water is less than 1000mg/L, but when TDS is more than 600 mg/L, it will accelerate the consumption of the power anode rod and shorten the service life of the water heater.

Saturation index of water that is prone to scaling:

• The calcium carbonate in the water can deposit on the surfaces of hot metal, which can cause scaling. When the saturation index of water is greater than 0.4, the scaling will be obvious. The higher the water temperature and water consumption, the more serious the scaling will be. In this case, it is required to install an expansion control valve after the non-return valve on the cold-water pipeline of the water heater.
• When the saturation index of water is less than -1.0, its corrosiveness will be very strong and it can dissolve copper pipes, but it will not have any effect on the water heater itself.
• For water quality supplied fails to comply with the Standard aforesaid, a water softening device is suggested to be installed to reduce the water hardness. However, the water-softening device is not able to remove all hardness. Therefore, scaling off periodically is recommended.

Maintenance

• Note: This water heater should be repaired and maintained only by qualified service personnel. Incorrect maintenance methods may cause serious injury to human body or property losses.
• Warning: Before disassembling the unit or taking any repairing/maintenance action, be sure to disconnect the power supply of the water heater.

Safety inspection
Check the performance of the safety valve every two weeks. Inspection method: Lift up the handle of the safety valve and observe whether there is water flowing out of the drainpipe. If no water is flowing out, please contact service provider for repair.

Note:
When checking the TPR valve, please be careful that water flowing out from the valve may cause scalding.

Jacket clean
To maintain the good appearance of the water heater, the surface of the jacket can be cleaned regularly as following procedures:

• Cut off the power supply of the water heater.
• Use a damp cloth to take a small amount of soap or detergent and lightly wipe the jacket. Do not use gasoline or other corrosive chemicals.
• Restart the water heater.

Water tank maintenance
It is recommended to clean the water tank once a year in places with good water quality, and once every six months in places with poor water quality.

The steps are as follows:

1. Cut off the power supply of the water heater and drain all the water in the tank
2. Connect the outlet pipe joint of the water heater to tap water and let water flow into the tank; open the drain valve and connect the drainpipe to the floor drain, and water is discharged from this end
3. Turn on the tap to maximum flow and flush the water tank until the water discharged from the water tank is clean.
4. Close the drain valve, reconnect the water pipe, and check if there is any leakage.

Suggestion:
In the case of sufficient hot water, users are recommended to lower the set temperature, which can reduce heat loss and scale accumulation, to save energy and prolong the service life of the water heater.
