SUMMARY OF ORAL EXPLANATIONS PROVIDED BY THE TREVI TECHNICIAN ON THE OPERATION AND MAINTENANCE OF YOUR IN-GROUND POOL VALVES The valve located in front of your pump is used to determine the source of water (your skimmer and / or your bottom drains). It also serves to shut off access to your pump. The valves located on your filter determine where water will be returned. It is important to never close all the valves at the same time; one should always remain open. FILTER Cartridge filter Check the pressure (PSI) on your gauge after installation. This should indicate normal pressure. When pressure increases by 5 to 10 psi, you should clean your cartridge(s) using a garden hose. The best way to clean is diagonally, from top to bottom. If necessary, use a cartridge cleaning product. Cartridge(s) should be cleaned at least once a year, when closing the pool. Sand filter Here are the different positions of the filter valve: • Filter: When the filter is in this position, it filters the pool water. Water enters the filter, is filtered by the sand and then returns to the pool through the water return jets. This is the usual position of the filter. • Winterize: Use this position to close the pool. It protects the mechanism inside the filter head. • Waste, Sewer, Drain: This position empties out the pool water by passing through the filter head only. It is recommended to vacuum in this position if there is a lot of waste or algae in the water, so as not to contaminate the sand in the filter. • Closed: This position prevents water from entering or exiting the filter. The pump must be closed when the filter is at this position. • Backwash: This position is used to rinse the sand which is in the filter and to decrease the pressure within the filter. It is recommended to perform a backwash every week, for a period of about 2 minutes each time. You can actually stop backwashing when the water exiting the hose becomes clear. As soon as the pressure of the filter exceeds normal pressure by 5 to 10 psi, you must perform a backwash • Recirculate: At this position, water flows through the filter head only and returns straight into the pool, without being filtered. Put the valve in this position only when your Trevi advisor recommends it. • Rinse: This position prevents debris from returning into the pool. It is used mainly after a backwash, and the valve should remain in this position for a period of time equal to half the duration of the backwash. Example: if your backwash took 2 minutes, then you should select the valve’s Rinse position for one minute. AQUA TROL AND SWIMPURE SALT SYSTEMS System and water maintenance • Add the bags of salt directly into the pool water; never put salt in the skimmer. Before adding products in water, turn off the salt system and unplug it. Add 3/4 bag of salt and wait 24 hours. After 24 hours, set your panel to “auto” and check the displayed salt level. If necessary, add ½ to 1 bag of salt per 12 hours, until the salt level settles between 2700 and 3200 ppm, or between 1200 and 1800 ppm for the “low salt” system. It is important to turn off the system and to unplug the cell before adding salt, and to wait 20 minutes before reconnecting everything. • Check the control panel to make sure that your salt level remains between 2700 and 3200 ppm, or between 1200 and 1800 ppm for the “low salt” system. • Using strips or drops, analyze your pool water weekly to ensure it is properly balanced. A chemical imbalance of your water will result in a loss of water quality and your liner may discolour or dry out very quickly. • You should adjust your device so that the percentage of chlorine produced is between 25% and 40%. You may have to increase this adjustment during summer heat waves, or if there are a lot of bathers. Ideally, you should not exceed 50%. • It is strongly advised to take the habit of adding PH- to your pool water at least once every 2 weeks, as salt systems tend to increase PH levels, which should ideally range between 7.2 and 7.6 ppm.
• The Hayward salt system does not work when the water temperature is below 58 ° F. • If the INSPECT CELL warning light on the device lights up, here is what you need to check: o The pool’s salt level. CHECK SALT should also be lit. o Check inside the cell to see if there is a scale deposit. If this is the case, clean the cell. o Make a “Reset” on the salt system casing. See RESET THE SALT SYSTEM instructions below. If the light stays on after you have checked the above, please contact Trevi at (514) 22-TREVI (87384) to obtain the help of a technician. CLEANING THE CELL The salt cell requires cleaning at least once a year, in spring or fall. Simply screw the cell onto the base designed for this purpose and pour some LECTRA CLEAN inside. Let stand 15 to 20 minutes. Then return the product into its bottle and rinse the cell with water before putting it back in place. RESET THE SALT SYSTEM When the INSPECT CELL light is turned on, press the DIAGNOSTIC button next to the display and hold for three seconds. If the light comes on again, check the salt level in water. If the salt level is adequate, inspect cell and clean if necessary. INSTANT SALT CALIBRATION Press the DIAGNOSTIC button 5 times. Set the switch to the OFF position, then return the switch to the AUTO position. When the numbers stabilize, set the switch to the SUPERCHLORINATION position, then return the switch to the AUTO position in order to save this data. DRY WELL The dry well (a hole in the ground covered with a lid, much like a skimmer) should be checked regularly, especially in heavy rain. If the water level rises more than 12 inches in the dry well, you should use an automatic submersible pump to keep the water level down. If the dry well is not regularly emptied, water could end up behind your pool liner and cause it to peel off. If water remains in the soil during winter, the consequences could be significant and very harmful. VACUUM Follow the instructions below to operate your pool vacuum: • Plug the rotary end of your vacuum hose into the vacuum head. • Insert the telescopic handle into the vacuum head. • Place the vacuum head in water. • Place the other end of your vacuum hose, non-rotating, in front of the water return in order to fill it with water, until you no longer see bubbles coming out of the vacuum head. • Connect the end of the hose to the suction plate that goes into the skimmer, and place it in the skimmer. • Now you can vacuum. If the water contains lots of waste or algae, those with a sand filter should vacuum with the filter in the WASTE position in order to avoid contaminating the sand in the filter. If the water contains lots of waste or algae, those with a cartridge filter must remove the cartridge before vacuuming in order to avoid contaminating the cartridge.
