Please remove the hollow plate after installation. NOTE Picture in this manual for reference only, please refer to the actual product. The backup heater can be customized outside the unit in accordance with demands，which contains 3kW(1-phase) , 4.5kW(1-phase), 4.5kW(3-phase), 6kW(3-phase) and 9kW(3-phase)（Please refer to the INSTALLATION & OWNER’S MANUAL of the backup heater for details). The backup heater(optional) and heat pump are independently powered.
1 SAFETY PRECAUTIONS The precautions listed here are divided into the following types.They are quite important, so be sure to follow them carefully. Meanings of DANGER, WARNING, CAUTION and NOTE symbols. i INFORMATION Read these instructions carefully before installation. Keep this manual in a handy for future reference. Improper installation of equipment or accessories may result in electric shock, short-circuit, leakage, fire or other damage to the equipment.
DANGER Before touching electric terminal parts, turn off power switch. When service panels are removed, live parts can be easily touched by accident. Never leave the unit unattended during installation or servicing when the service panel is removed. Do not touch water pipes during and immediately after operation as the pipes may be hot and could burn your hands. To avoid injury, give the piping time to return to normal temperature or be sure to wear protective gloves.
Do not install the unit in the following places: - Where there is mist of mineral oil, oil spray or vapors. Plastic parts may deteriorate, and cause them to come loose or water to leak. - Where corrosive gases (such as sulphurous acid gas) are produced. Where corrosion of copper pipes or soldered parts may cause refrigerant to leak. - Where there is machinery which emits electromagnetic waves. Electromagnetic waves can disturb the control system and cause equipment malfunction.
2 GENERAL INTRODUCTION These units are used for both heating and cooling applications and domestic hot water tanks.They can be combined with fan coil units, floor heating applications, low temperature high efficiency radiators, domestic hot water tanks and solar kits, which are all field supplied. A wired controller is supplied with the unit . The backup heater（Optional） can increase the heating capacity at pretty low outdoor temperature.
In cooling mode, the water flowing temperature (TW_out) range in different outdoor temperature(T4) is listed below: 3 ACCESSORIES 3.
4 BEFORE INSTALLATION Before installation Be sure to confirm the model name and the serial number of the unit. Transport Due to relatively large dimensions and heavy weight, the unit should only be hoised by lifting tools with slings, please refer to the following picture. CAUTION Foam To avoid injury, do not touch the air inlet or aluminum fins of the unit. Protect Angle Do not use the grips in the fan grills to avoid damage.
CAUTION Frequency of Refrigerant Leakage Checks For unit that contains fluorinated greenhouse gases in quantities of 5 tonnes of CO2 equivalent or more,but of less than 50 tonnes of CO2 equivalent,at least every 12 months, or where a leakage detection system is installed, at least every 24 months.
In normal condition,refer to the figures below for installation of the unit: A If you install the unit on a building frame, please install a waterproof tray (field supply) (about 100mm, on the underside of the unit) in order to avoid drain water dripping. (See the picture in the right). Unit 5~16kW A(mm) 6.

The operation mode and setting temperature are set on the user interface. Due to changes of the outdoor tempearature and the required load indoors, multiple outdoor units may operate at different times.
1. In cascade system, Tbt sensor must be connected to master unit and set Tbt vaild on user interface，otherwise all slave units will not work. 2. If outside circulation pump need to be connected in series in system when the head of internal water pump is not enough, outside circulation pump is suggested to be installed after the balance tank. 3. Please ensure that the maximum interval of power-on time of all units doesn’t exceed 2 mins, which may cause the slaves to fail to communicate normally. 4.

9.3 Water piping All piping lengths and distances have been taken into consideration. Requirements The maximum allowed thermistor cable length is 20m. This is the maximum allowable distance between the domestic hot water tank and the unit (only for installations with a domestic hot water tank).The thermistor cable supplied with the domestic hot water tank is 10m in length.In order to optimize efficiency we recommend installing the 3-way valve and the domestic hot water tank as close as possible to the unit.
Before continuing installation of the unit, check the following: The maximum water pressure ≤ 3 bar. The maximum water temperature ≤ 70°C according to safety device setting. Always use materials that are compatible with the water used in the system and with the materials used in the unit. Ensure that components installed in the field piping can withstand the water pressure and temperature.
9.3.3 Water circuit connection Water connections must be made correctly in accordance with labels on the outdoor unit, with respect to the water inlet and water outlet. 9.3.4 Water circuit anti-freeze protection All internal hydronic parts are insulated to reduce heat loss. Insulation must also be added to the field piping. In event of a power failure, the above features would not protect the unit from freezing.
CAUTION When the unit is not running for a long time, make sure the unit is powered on all the time. If you want to cut off the power, the water in the system needs to be drained clean to avoid the unit and piping system be damaged by freezing. Also the power of the unit needs to be cut off after water in the system is drained off. . WARNING Ethylene Glycol and Propylene Glycol are TOXIC 9.4 Filling water Connect the water supply to the filling valve and open the valve.
9.5 Water piping insulation The complete water circuit including all piping, water piping must be insulated to prevent condensation during cooling operation and reduction of the heating and cooling capacity as well as prevention of freezing of the outside water piping during winter. The insulation material should at least of B1 fire resistance rating and complies with all applicable legislation. The thickness of the sealing materials must be at least 13 mm with thermal conductivity 0.

NOTE Please use H07RN-F for the power wire, all the cable are connect to high voltage except for thermistor cable and cable for user interface. Equipment must be grounded. All high-voltage external load, if it is metal or a grounded port, must be grounded. All external load current is needed less than 0.2A, if the single load current is greater than 0.2A, the load must be controlled through AC contactor. “AHS1" "AHS2" wiring terminal ports only provide the switch signal.
9.6.4 Safety device requirement 1. Select the wire diameters( minimum valve) individually for each unit based on the table 9-1 and table 9-2， where the rated current in table 9-1 means MCA in table 9-2. In case the MCA exceeds 63A, the wire diameters should be selected according to the national wiring regulation. 2. Maximum allowable voltage range variation between phases is 2%. 3.

When connecting to the power supply terminal, use the circular wiring terminal with the insulation casing (see Figure 9.1). Use power cord that conforms to the specifications and connect the power cord firmly. To prevent the cord from being pulled out by external force, make sure it is fixed securely.
9.6.6 Connection for other components unit 5-16kW See 9.2.1for detailed port description. Port provide the control signal to the load.Two kind of control signal port: Type 1：Dry connector without voltage. Type 2：Port provide the signal with 220V voltage. If the current of load is <0.2A, load can connect to the port directly. If the current of load is >=0.2A, the AC contactor is required to connected for the load.
