Cut off the manual

power switch

Prohibit

For long-term use, check whether the installation bench is firm and intact. If installation bench is damaged or weak, the outdoor unit may fall, causing casualties.

Stop the operation during cleaning, and cut off the manual power switch. If the machine does not stop operation, it may cause injury due to the wind wheel running at a high speed inside.

Use the appropriate fuse. If copper or iron wires are used, it may cause malfunction or fire.

Do not spray the combustible spray directly to the outdoor unit; otherwise, this may easily

Installation precaution

Do not install it in a place where flammable gas leak easily occurs. Once the flammable gas leaks and stays around the outdoor unit, this may cause a fire.

Verify whether the leakage protection switch has been installed. If the leakage protection switch is not installed, this may cause electric shock or fire.

Verify whether the installation base is solid. If the base is not solid, the outdoor unit may fall and then result in accidents.

2.4 Caution

Verify the installation site

5.6 Water Pipe Connection

5.7 Electrical Wiring

5.Installation

5.6 Water Pipe Connection

Note the following items during connection of water inlet and outlet pipes:

`

Minimize the resistance of the water pipe outside the unit.

The entire piping system should be clean and free of dirt and rust to prevent pipe clogging. Test for leakages after the pipes are installed to ensure that the entire piping system is free of leakage, and then coat with the insulating layer.

The pipeline should be conducted with a pressure test separately, rather than together with the air conditioning main engine.

An expansion water tank should be installed at the highest point of the water distribution pipeline, where the highest point of the water level in the expansion water tank is at least 0.5 meters higher than the water distribution pipe.

Flexible joints should be used between the unit interface and the field piping to reduce the vibration spread to both buildings and equipment. Both the pipe and the fittings must be independently supported, but should not be supported by the unit.

The thermometer and the pressure gauge should be installed at the water inlet and outlet pipes of the unit to facilitate the inspection during operation.

Drainage interfaces should be installed at all low positions of the water system (the unit has a drain port to facilitate drainage; interfaces will be added in other positions on site) so that the water in the system will be completely drained if it is not used in winter; automatic exhaust valves should be installed at all high positions so as to facilitate to exhaust the air from the pipeline. No insulation is provided for both the exhaust valves and the drain port for easy maintenance.

5.7 Electrical Wiring

Open the panel, and open the power line hole

Thread the power line through the hole and connect it to the power line terminal; and the three-core control line of the remote controller shall be plugged with the three-core signal line on the main board according to the wiring diagram.

For an external water pump, thread the power line of the water pump through the hole and connect it to the water pump terminals.

If it is necessary to automatically control the auxiliary heat source, connect the control output signal of the auxiliary heat source to the start switch of the auxiliary heat source.

If it is necessary to automatically control mode of the air conditioning terminal, connect the mode control signal to the mode control switch on each indoor air conditioning terminal.

Warning

Do not touch the radiating fins behind the machine by hand or with other objects!

When lifting is needed, use four sling wires longer than 8m for lifting; during the lifting, use the special lifting hole (hook) on the unit base. Pads shall be provided at the contact between the housing and the sling to prevent the damage to the housing, as shown in Figure 2.

5.Installation

5.9Trial Operation

Check the piping system. Check whether the expansion water tank is filled with sufficient water and whether the water supply for supplement is normal. Check whether the entire piping system is full of water and whether the air is completely exhausted. Check whether all valves in the system are opened. Check whether the pipelines are well insulated.

Check the power distribution system. Check whether all power supplies have normal voltage. Check whether screws of each power distribution part are locked, and whether the power is distributed to the circuit according to the distribution wiring diagram. Check whether the ground line is well connected.

Check the water chilling unit. Check whether all fastening screws and screws on the mechanical parts of the unit are firm. Check whether there is any fault indication on the operation lights on the outdoor control main board. Connect the pressure gauge to the fluoridated inlet to detect the system pressure during operation.

5.9.1 Check prior to trial operation

13

5.Installation

Turn on the machine with on the remote controller, and then immediately check whether the water pump operates normally; if it is normal, observe the water flow switch and the water pressure gauge of the water system: when the water flow switch is in the ON state, the water pressure gauge shall show the water pressure of about 0.2MPa.

After the water pump has operated for some time, the compressor will start. Judge

whether there is any abnormal sound in the unit during operation with the sense of hearing; if there is any abnormal sound, immediately cut off the power and check the unit; if there is no abnormal sound, continue the operation and then note whether the pressure of the refrigerating system is normal.

Check whether the input power and the current of the unit are consistent with the performance data list in the Manual; in case of incompliance, stop the unit for check.

Adjust the water supply valve in each room, so that the temperature of each room meets the use requirements.

Observe whether the outlet water temperature is normal.

Parameters of the remote controller have been set in the factory, and the user shall not adjust it without permission.
