WARNINGS:

1. This unit must be installed byAUTHORIZED personnel only. Manufacturer cannot be heldliable for accident or injuryresulting from incorrect installation or operation of the unit.

2. Do not have the power supply to the unit on during installation or servicing of the unit.3. Unit must not be installed near flammable objects.WATER TEMPERATURE ADJUSTMENT

Safety and energy conservation are factors to be considered when selecting the water temperature setting via the waterheaters user interface. Water temperatures above 125F can cause severe burns or death from scalding. Be sure to readand follow the warnings outlined on the label pictured below. This label is also located on the water heater near the top ofthe tank.

A. Important remarksPlease note the following before installing the unit:

1. This unit is for indoor installation only.

2. Ambient temperature range for operating theheat pumpis35~110.3. The air vent (for exhaust air) of the unit needs a minimum clearance of3feet from the ceiling. Do not

insert your hand or any object into the vent.

4. Ensure that the unit is installed on a flat surface. Unit should be secured properly to the base and

should stand in an upright position.

5. While moving or installing the unit, ensure that the unit does not incline more than 30degrees.6. To let the unit run efficiently, install the unit at a place with properventilation.7. Ensure that the unit is installedon a dry surface. Water inflow and outflow lines should be sealed to

prevent leaks. Condensate water should be drained.

8. Ensure that the unit is wired to a 220V power outlet that is rated for at least 30amperes.9. Do not change wiring scheme. Ensure wiring safety standards are met. Ensure earthing.

10. Before turningon the unit, ensure the unitis full with water.

C. Installation instructions

Note:

1. Unit should be installed indoors in an unobstructed space. Minimum clearance space (in millimeters) is

highlighted in the figures below. Air outlet vent maybe connected to a 6-inch (diameter) air duct.

(Fig.1) (Fig.2)

2. Unit should stand vertical at 90degreesdo not let the unit lean against a wall or another object.3. Ensure proper ventilation in the area where the unit is installed.

5. Ensure both condensate water pipes are drained.

6. For water inlet and outlet connections, please refer to Fig.3below.7. Water pressure inside the tank must not exceed 0.7MPa. Ensure T&P valve is operational.

8. Inlet water must have a minimum pressure of0.1MPa.9. Ensure the water tank is full with water before turning on the system.

E. Maintenanceand serviceExamination 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 oroutlet 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 earth-wire 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 3minutes 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 toreset it, the maintenance person should be carefully set if needed.
