RENOVATION - SERAPOOL Porcelain

112 BEFORE SERAPOOL l RENOVATION very important that the pool is empty, the electrical installation is turned off at the main switch, and occupational health and safety measures are taken. Lighting and ventilation must be available in the area where dismantling will take place. Points to Consider During Equipment Dismantling, Maintenance, and Renewal Processes First, a comprehensive survey must be carried out, and the dismantling process must be carried out in sequence and according to a schedule. After dismantling, the pumps must be maintained (the motor winding, mechanical seal, shaft, impeller, and pump electrical box must be renewed). Filter covers should be opened to check the sand, and if it is dirty, it should be washed with chemicals. Sand should be added according to the filling sequence (first gravel, then coarse sand, and finally fine sand). All salt components in the pool pump and electrical panel must be inspected and replaced if necessary. The panel must have residual current devices. Power and grounding lines must be checked. Disinfection pumps and chemical tanks, as well as chemical filling lines, must also be inspected. Machine room entrances, access ladders, and gravity ventilation must be provided; if gravity ventilation is not available, forced ventilation must be installed. Wastewater drains must be cleaned and made functional. In overflow pool systems, balance tanks should be cleaned and coated with light-colored coating material (white if possible). IP67 lighting that is not affected by steam should be installed near the access windows, and the water level should be visible from the machine room. Most Common Construction Errors in Water Circuits and Equipment Common errors include the use of plaster-screed insulation and pool coatings that are not of the required quality and care in the construction of pools; if the pool has a top overflow system (this system is usually used), the overflow levels are not equal at every point in the pool. Furthermore, when constructing pool overflow channels, if they are not built together with the side wall and are instead created later by adding a sprout, and if this channel cannot bear the terrace load, concrete cracks may occur inside the channel, and this issue should be taken into consideration. The use of coating materials that are not antibacterial and their incorrect application in the pool interior and surrounding terraces are also observed as critical construction errors.
