Fan coil system general engineering site and coil connected to the pipe part of the valve, filter and hose and other special-shaped pipe fittings, insulation is not easy to compact, and daily maintenance often dismantled, it is easy to cause condensate dripping, engineering practice, can be used for return water local pipeline slope to the coil side of the method to prevent and remedy.
The poor drainage of condensate water is mostly manifested as overflowing water at the condensate water receiving tray of the fan coil unit. During the operation and use of the air conditioning system, local stress is too large or the support and hanger are invalid, which is easy to cause slope change or local water storage, and condensate water overflow. This requires strict control of the slope of the water pipe during installation, dredge the drainage pipeline and control the reasonable spacing with other pipelines, not too close to prevent accidental force deformation, and check the installation fixing points of supports and hangers to prevent deformation and falling off. During the construction process, some people think that as long as the water is fed from the highest point of the condensate pipe network, the lowest point of the fan coil can be discharged. However, it is not enough to only discharge water, and the same amount of water should be guaranteed. Otherwise, there will be local water storage problems. The fan coil air conditioner is also easy to accumulate impurities and breed bacteria moss, and plug the pipeline for long time, this kind of problem must be strengthened construction management, and it is difficult to find and deal with it after the condensate pipe is insulated.

Preparation before installation.
1. Before unpacking, check whether the package is complete, whether the nameplate parameters of the fan coil meet the requirements, and whether all accompanying accessories are complete.
2. Carefully check whether the fan coil is deformed or damaged during transportation, whether the fastener is loose or falling off, whether the impeller has rubbing phenomenon, and check the parts of the fan coil. If any abnormal phenomenon is found, it should be repaired before use.
3. Use a 500V megohmmeter to measure the insulation resistance between the fan coil housing and the motor winding. The value should be greater than 0.5 megohms. Otherwise, the electric fan coiling machine should be dried, and the temperature during drying must not exceed 120 ℃.
4. Prepare all kinds of materials, tools and sites required for fan coil installation.

Installation.
1. Carefully read the instruction manual and product samples of the fan coil, be familiar with and understand the specifications, form, rotation direction of the impeller and air flow in and out direction of the fan coil, and check again whether the parts of the fan coil are in good condition, otherwise it should be repaired before installation and use.
2. The fan coil must have safety devices to prevent accidents when installing, and be installed and wired by professionals familiar with relevant safety requirements.
3. The air pipes connecting the inlet and outlet of the fan coil are supported separately. It is not allowed to add the overlapping weight of the pipes to the components of the fan coil. The horizontal position of the fan coil should be paid attention to when installing the fan coil. The connection between the joint surface of the fan coil and the foundation and the air outlet pipe should be adjusted to make it naturally coincide, and the fan coil connection should not be forced.
4. After the fan coil unit is installed, toggle the impeller by hand or lever to check whether there is over-tightening or rubbing, whether there are any articles that hinder rotation, and test operation can be carried out only if there is no abnormal phenomenon. The exposed part of the fan coil unit transmission device shall be provided with a protective cover (provided by the user). If the air inlet of the fan coil unit is not connected to the pipeline, a protective net or other installation device (provided by the user) shall be provided.
5. The electric control box of the fan coil must be matched with the corresponding fan coil (referring to power, voltage, pneumatic mode, control mode, etc.).
6, fan coil wiring should be professional electrician wiring, wiring must be correct and reliable, especially the electric control box at the wiring number and fan coil terminal number on the same correspondence, fan coil shell should be reliable grounding, grounding must be reliable, can not use zero instead of grounding.
7. After the fan coil is fully installed, check whether there is any tool box debris left inside the fan coil.
