2. Description of drainage drainage system.
The project provides for a drainage drainage system from fan coils. Condensate, which is collected in the fan coil pan, is pumped out by the pump and fed into the main pipeline, then through the dropping funnel, the condensed water is drained into the sewer risers. To ensure natural condensate through pipelines, a pipe slope of 0.003mm / m is provided in the drainage system of fan coils.

3. Instructions for installation, operation and maintenance.
- condensate pipes must be laid with a slope of at least 3 mm / m;
- all pipes must be securely fixed at regular intervals;
-in the system should not be protivokononov;
- pipe slope should start as close as possible to the outlet branch pipe of the unit;
-radius of the knees should be as large as possible so that the hydraulic resistance of the pipeline is as low as possible;
- the lifting height of the bypass pipe must not exceed the maximum pump head specified in the instructions supplied with the unit;
- Use only the outlet pipe of the diameter specified in the instructions supplied with the unit.
