Cartridge Filter Installation and Maintenance

 

Location

The filter should be placed in its permanent location, preferably close to the pool or spa. Position the filter tank and pump on a level concrete slab or similar base. Allow sufficient space around the filter for routine maintenance and adequate ventilation and drainage. Place the pump on the slab and locate the filter alongside the appropriate pump inlet connection oriented towards the pump.

 

Weather Protection

Emaux cartridge filters are made of corrosion-resistant materials. However, to ensure years of reliable performance, the filtration system is recommended to be adequately protected from the weather.

 

Assembly

Assemble the pressure gauge to the filter lid using Teflon tape on the male thread. Do not over-tighten.

 

Pipe Connections

Piping should be supported independently and not impose heavy loads on the filter or pump. Use 40mm or 50mm PVC pipe for the pump and pool return lines. 50mm should always be used if the length of the piping is over 15mm. Emaux cartridge filters are supplied with quick-connect couplings suitable for 40mm LD PVC pipe or 50mm OD fittings.

If the pump and filter are located below pool water level, it is necessary to fit isolating valves in the pipe between the pump and the pool and in the return line from the filter to the pool.

1. Pump to Filter
    Emaux cartridge filters have two inlet ports marked as “INLET.” Select the inlet port most suitable for the installation, and plug the other one with the provided blanking cap. Using quick-connect couplings, connect the pool pump delivery piping to the selected inlet port. Tighten by hand only. Ensure the O’ring on the fitting is clean, lubricated with O’ring lubricant, and in the correct position.

1. Filter to Pool Return
    Using quick-connect couplings, connect the pool return piping to the filter fitting marked as “OUTLET.” Tighten the fitting by hand only. Ensure the O’ring on the fitting is clean, lubricated with O’ring lubricant, and in the correct position.

 

Filter Operation

  1. Make sure the pump is primed according to the manufacturer’s directions.
  2. Make sure all valves are open on suction and discharge lines. Also, make sure the air bleed valve on the filter lid is open and the lock ring is secure.
  3. Start the pump. Close the air bleed valve when water is expelled.
  4. To determine the correct operating conditions with a clean filter, make sure the pressure gauge reads 80 kPa or below.
  5. Record the pressure gauge reading, or mark the needle position on the face of the pressure gauge.
  6. Operate the filter for a sufficient time to circulate the total pool water volume daily. The filter should also be operated when the pool is in use and for about one hour afterward. During winter, the running time may be reduced. Filter operating requirements will vary for spa applications, depending upon the spa’s system design, type, and size.
  7. When the pressure gauge reading is 50-70 kPa higher than the “clean filter” reading mentioned in item no. 4, it is time to clean the cartridge element.

 

Cartridge Cleaning Procedure

  1. Switch off the pump.
  2. Close isolating valves on suction and discharge lines where fitted.
  3. Open the air bleed valve on the filter lid. Unscrew the lock ring, and remove the filter lid.
  4. Lift out the cartridge element.
  5. In most cases, the element can be easily cleaned by pressure-washing inside and out with a garden hose, spraying good velocity directly on the pleats.

 

NOTE: Algae, calcium, clay, suntan oil, and body oils can form a coating on the element, which may not be easily removed with normal hosing. These materials can be removed by soaking the element in a degreaser or descaler.

 

Cartridge Reassembly Instructions

  1. Install the cartridge/s and center pipe so that it is located in the bottom spigot.
  2. Make sure the filter lid O’ring is clean, lubricated with O’ring lubricant, and located in the bottom groove.
  3. Replace the lid and press firmly in place. Screw down the lock ring. Tightening by hand is sufficient. Do not over-tighten.
  4. Make sure the pump is primed according to the manufacturer’s directions.
  5. Make sure all valves are open on suction and discharge lines.
  6. Start the pump.
  7. Close the air bleed valve when all air has been expelled.
