Fan coil installation method and specification of common sense, winter must adopt antifreeze measures to prevent pipe frost crack, fan coil cold water inlet temperature, generally choose 7 ℃ ~ 10 ℃, cold water temperature rise to 5 ℃, hot water inlet temperature generally choose 50 ℃ ~ 60 ℃, under possible conditions, should try to improve the cold water inlet temperature and reduce the hot water inlet temperature.
Before the on-site installation of the fan coil unit, the pressure test shall be carried out to check whether the coil and each valve leak, and the fan impeller shall be moved to check whether there is any foreign matter stuck.
The weight of the air and water pipes connected to the fan coil unit shall not be borne by the unit.
Drainage pipes shall have sufficient slope to ensure smooth drainage.
The temperature of the hot water supplied by the fan coil in winter should not be higher than 80 ℃, the supply of clean softened water is required, and the cold water supplied in summer should not be lower than 6 ℃.
The return pipe of the fan-coil unit is equipped with a manual bleed valve. The bleed valve shall be opened before operation, and the bleed valve shall be closed after the air in the fan-coil coil and pipeline is exhausted.
Double-sided dustproof and self-lubricating bearings are used for fan coil motor bearings. Lubricating grease has been added to the bearings. It is not necessary to add lubricating grease regularly.
When installing the inlet and outlet pipes of the fan coil unit, a thermal insulation layer shall be added to generate condensed water when the rabbit is used in summer. Sealing measures shall be taken at the threaded connection (polytetrafluoroethylene raw material belt is selected). The inlet and outlet pipes must be aligned with the external pipe. Hose connection is recommended. When connecting the electric heating film, do not use too much force, causing the coil to twist or leak.
When the fan coil unit is installed, the condensate plate should be slightly inclined to the direction of the outlet joint to ensure smooth drainage.
The fan coil heat exchanger should be regularly purged and kept clean to ensure good heat transfer performance. The unit equipped with a filter should regularly clean the filter to ensure smooth return air. Generally, it should be cleaned once every 3 months.
Fan coil unit shell must be reliably grounded, fan coil.
When the fan coil system is not used, it should be filled with water. In winter, where the water pipe may freeze, anti-freezing measures should be taken.
The electrical wiring of the unit shall be carried out according to the attached wiring diagram, and it is forbidden to control two or more units with one switch.
When handling the fan coil unit, handle it with care. Do not put your hand into the fan volute to lift it, so as not to cause impeller deformation, increase noise and affect the use effect.
Before the installation of the fan coil unit, check the complete edge of the motor, the performance of the fan and the steering of the impeller to see if they meet the design requirements, and check whether the connection points are loose to prevent additional noise, and check the type of ground source heat pump and the direction of the connection (I. e. left or right) according to the design requirements, and then install it after confirmation.

Fan coil is noisy.
Problem: The noise of the air coil in the hotel room is too loud.
Reasons: 1) The actual noise level of all kinds of fans at home and abroad is generally high, and only a small part of the fan coil is low. The noise of domestic fan coil has reached the international level.
2) Due to the different installation position and configuration of the fan coil in the guest room, the level of indoor noise is also different. When the fan coil is turned on at high speed, the upper limit of noise is -45, the lower limit is -35, the upper limit is -40 at low speed, and the lower limit is -25.
Solution:.
1) The installation position of the fan coil unit should be considered according to the level of the room in the design selection. When the bedroom with high requirements is concealed, noise reduction can be done in the air duct between the outlet of the fan coil unit and the air supply outlet of the room. The column fan coil unit should be set up far away from the bed and the table, and the air outlet can also be equipped with noise reduction device. For general requirements, horizontal or vertical fan coil unit with medium noise can be selected.
2) Reduce the room temperature to 23~24 ℃ during the day, and even if the fan coil is turned off at night, the indoor temperature will not be too high.
