Before use 1.1 Advanced Important Notice Cautions: 1.Do not use means to accelerate the defrosting process or to clean,other than those recommended by the manufacturer. 2.The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames, an operating gas appliance or an operating electric heater.). 3.Do not pierce or burn. 4.Be aware that refrigerants may not contain an odour. 5.
1. Before use 3) General work area All maintenance staff and others working in the local area shall be instructed on the nature of work being carried out. Work in confined spaces shall be avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been made safe by control of flammable material.
1. Before use 9) Checks to electrical devices Repair and maintenance to electrical components shall include initial safety checks and component inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution shall be used.
1. Before use 9.Cabling Check that cabling will not be subject to wear,corrosion, excessive pressure, vibration, sharp edges or any other adverse environmental effects. The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans. 10.Detection of flammable refrigerants Under no circumstances shall potential sources of ignition be used in the searching for or detection of refrigerant leaks.
1. Before use 13.Charging procedures In addition to conventional charging procedures, the following requirements shall be followed. – Ensure that contamination of different refrigerants does not occur when using charging equipment. Hoses or lines shall be as short as possible to minimise the amount of refrigerant contained in them. – Cylinders shall be kept upright. – Ensure that the refrigeration system is earthed prior to charging the system with refrigerant.
1. Before use the total system charge is available. All cylinders to be used are designated for the recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief valve and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible, cooled before recovery occurs.

8. Electric Heater This unit has included two electric heaters inside. Two electric heaters are used to keep the water temperature when heat pump capacity is not enough or heat pump fail to work, as well as heat the water up more rapidly when water temperature is low. 【500W electric heater】 1. 500W electric heater only can be controlled by digital thermostat. 2. Power supply is 230V/50Hz/1Ph, and temperature setting range is 30~75℃. 3.
8. Electric Heater When heat pump capacity is not enough, or heat pump meets a failure, indoor PCB will turn ON the internal heater automatically. However, if the indoor PCB itself is broken, one can obey the following instructions to turn ON the heater manually: 2 1 Emergency switch K1 Mechanical thermostat Switch ON the switch K1 inside the unit, as shown in below picture. Unscrew three screws on top, and lift the front panel up by around 20mm, then remove the front panel.

9. Failure Code Type Code Description S04 Communication failure S05 Serial port connect error Blinking times Water outlet Temp. S07 too high protection in heating/hot water Water outlet Temp. S09 too low protection in heating/hot water Too small water flow S10 rate failure If unit stops due to “too small water flow rate”protection code(S02) over three times in certain period of time, unit stops and gives S10 Compressor stops failure code. It can only be recovered by re-powering the unit.
10. Attention A．The user mustn't change the structure or wiring inside the unit. B．The service and maintenance should be performed by qualified and well-trained technician When the unit fails to run, please cut off power supply immediately. C．The smart control system can automatically analyze various protection problems during daily use, and display the failure code on the controller. The unit may recover by itself. Under normal operation, the pipings inside the unit don't need any maintenance.
11. Service 【 Indoor unit】 Service on indoor unit as follows: (this operation must be done by qualified personnel) 1. Cut off the power supply 2. Remove the front panel(Be care about the cables in between) 3. Check the electric part 3 1 2 【Outdoor unit】 1.Maintenance of controller a. Cut off the power supply. b. Disconnect all cables. c. Unscrew 4 screws, you can take this controller off.
11. Service 【Indoor PCB】 2 1 1. LED indicator light on Indoor PCB ON 2. Dip switch on indoor PCB Factory Default Setting: OFF 【Outdoor PCB】 2 1 1.Dip switch on outdoor PCB Factory Default Setting ON 2.
11. Service 2. Replacement of fan motor a. Take off screws of the front grill (see picture a and b). b. Use a wrench to loosen the nut for fan blade and take out the fan blade(see picture c and d). c. Unscrew the screws of fan motor (see picture e). d. Then unscrew the small handle (see picture f). a c b Front grill d f e Fan blade Fan motor e. Tracking and take out the ground and power cable for fan motor, and take the whole fan motor with cables out. (see picture g, h, i and j). f.
12. Maintenance 4. Replacement of temperature sensor a. Take off the back panel (see picture a). b. Take out the broken sensor from its fixture, and also pull its connector out from the controller. c. Put the new sensor back and connect it to the same port on controller. a b c Back panel Sensor connector Temperature sensor 【Cleaning of water filter】 The water filter should be cleaned according to the manual of water filter, to ensure the water flow of the water system.
12. Maintenance 【Gas Charging】 The refrigerant plays an important role in delivering energy in cooling or heating. Insufficient refrigerant affects directly efficiency of cooling and heating. Please pay attention to the following before adding refrigerant: A. The work should be done by professionals B. Please make sure the copper pipe has no leakage before gas charging. If the copper pipes has leakage, please repair or change the pipes firstly. C.
13. Trouble-shooting Failure Cause 1. No power supply 2. Fuse is broken or circuit breaker is disconnected Unit can’t start up Fan fails to run Low heating performance 3. Some kind of protection works 5. compressor fails 5. Change a compressor 1. Fan motor wire loose 1. Check the wire connections. 2. fan motor failure 2. Change fan motor. 1. The coil fins are very dirty 1. Clean the evaporator coil 2. Air inlet is blocked 2. Remove any object that blocks the air circulation of the unit. 3.
