Frequently Asked Questions - APV650 ASTRALPOOL

What type of sand should I use in my AstralPool APV650 filter?

Use approved quartz silica sand with a grain size of 0.4 to 0.55 mm. The required amount is 150 kg (330 lbs).

How do I backwash the APV650 filter?

Turn the pump OFF, set the valve to Backwash, start the pump and run for 3 minutes, then turn pump OFF, set to Rinse and run for 1 minute, then return to Filter.

When should I backwash the filter?

Backwash when the pressure gauge reads 30 to 40 kPa higher than the starting pressure. Regular backwashing (at least 5 minutes each time) ensures the sand is completely cleaned.

What is the maximum operating pressure for the APV650?

The maximum operating pressure is 250 kPa. Do not exceed this pressure.

How do I start up the filter for the first time?

After loading the media, prime the pump, set valve to Backwash, run for 3 minutes. Then turn pump OFF, set to Rinse, run for 1 minute. Finally set to Filter and restart pump.

Can I install the filter below pool level?

Yes, but you must install isolating valves to prevent flooding from back-up water from the pool or spa.

What should I do if the pump loses prime?

Turn off the pump, remove the strainer lid, fill the strainer with water (about 4 liters), replace the lid, and restart the pump. Ensure all valves are open.

How do I winterize the APV650 filter?

Drain the filter by opening the winter drain on the underside. Remove all water from the pump and filter. Store the multiport valve in a protected area if possible.

What is the purpose of the 'Rinse' position?

The Rinse position is used after backwashing to flush out any remaining dirt and to level the sand bed. It is also used during initial start-up.

How do I connect the plumbing to the multiport valve?

Use the provided barrel unions (40mm or 50mm). Hand-tighten only; do not use Teflon tape. Ensure O-rings are in place between the valve and unions.

GENERAL NOTES

I. When unpacking the filter, be sure the unit is complete and no visible shipping damage has occurred.
2. Allow sufficient clearance around filter system for access and maintenance. If installed in a plant room, ensure there is sufficient access to remove filter at a later date.
3. Provide adequate ventilation for pumping equipment, installed in conjunction with filter.
4. Provide solid mounting for filter and pump. If installed outdoors, install the system on a slab or solid concrete base to avoid risk of settlement. Filter systems once located with media can exceed a weight of 500 kg. Pump, filter and other connecting equipment should be located on the same slab.
5. Installation of filters and pumps should be located as close to the pool as possible to avoid excessive piping friction loss.
6. If system is installed below pool level it is important to install isolating valves to prevent risk of flooding from back up water, from the pool or spa.
7. The proper media selection is critical to good filter performance. Ensure that the media is an approved Quartz Silica with a sizing range of 0.4 to 0.55 mm.
8. The installation of filters requires no special tools. An Allen key is provided with the filter to tighten the multiport valve clamps.
9. Confirm that plumbing lines from pool are correctly identified. This will ensure proper connection to markings on filter valve (i.e. "Pump", "Waste", and "Return").
10. The tank should be situated in such a way to allow easy access to winter drain on underside of filter.

LOADING FILTER MEDIA

Once the filter system has been positioned, the installation of filter media may be undertaken as follows:

I. Check filter size in order to determine necessary amount of media required.
2. Double check that the internal system consisting of a lateral hub and stand pipe are intact inside the tank.
3. Fill tank half full with water.
4. Place the disposable metal loading disc into the upper tank opening and the plastic cover over stand pipe to stabilise the filter and stand pipe. It is important that the stand pipe remains centered through the media loading procedure to ensure alignment with valve assembly opening.
5. Proceed to load correct volume of dry media slowly (if media is saturated loading can be difficult). Generally, a coffee can or funnel, can aid in the loading process.
6. Once media is loaded discard loading disc and check to determine if stand pipe is properly centred in tank opening.

I. Following the media loading, clean any media particles or debris from upper surface of tank opening.
2. Install six (6) position selector valve after placing O-Ring in cavity in underside of valve body. Place valve into tank opening while ensuring that the O-Ring has remained in position.
3. Install selector valve into top tank opening and rotate valve to best suit plumbing lines. Once positioned, fit clamp band assembly around neck of filter and valve and tighten sufficiently for good engagement. Note: An Allen key is provided to tighten the bolts in the clamp band.
4. Double check that incoming pool lines are connected to appropriate valve openings as marked on valve port (i.e. pump, return (pool) and waste).
5. The threaded openings on valve are 40mm or 50mm thread which all accommodate Astralpool barrel unions supplied with MPV. O-rings are supplied to fit between the multiport valve and barrel union. It is only necessary to tighten by hand. The use of Teflon tape is not required.
6. Remove white plug from side wall of valve and install threaded pressure gauge using Teflon tape wrap (do not over tighten). Minimum hand tightening is adequate to provide a good seal.

VALVE OPERATION

The operation and the positions of valve settings are as follows:

Valve Settings	Direction of flow through Valve
Filter (also during vacuuming)	From pump down through valve, through sand bed, up through stand pipe to valve and back through pool return.
Back Wash	From pump, through valve, down through stand pipe, up through sand bed, and through valve to waste.
Rinse	Flow from pump, through valve, down through sand bed, up through stand pipe, through valve to waste. (Position also used for initial start-up and leveling sand bed after Back-wash)
Waste	From pump, through valve to waste. Also position for lowering water level or assist in draining pool.
Closed	From pump to valve without further circulation. Prevents any flow to filter and pool.
Recirculate	From pump through valve to pool. This position bi-passes the filter and is used for circulation of pool water only.

NOTE: Always "STOP" pump when changing selector valve position.

I. With the pump OFF, remove the lid from the pump strainer and pour in approximately 4 litres of water.
2. Replace lid.
3. If valve has been installed on the pump suction line, close before filling strainer. Open again after lid has been securely fastened in place. Any valves on the return lines should be open. The pump should not need to be reprimed unless the pump has been drained for servicing, or winterizing (refer to complete pump operations manual provided with pump).

INITIAL START - UP

I. Make sure the correct amount of media is in the filter tank.
2. Prime pump.
3. Set valve handle in BACK WASH position.
4. Start pump and operate in BACK WASH cycle for three (3) minutes. This will purge the filter of excess fines in the media.
5. Turn pump OFF and set valve handle to RINSE. Start pump and run for one (1) minute.
6. Stop pump and set valve handle to FILTER. Restart pump. System is now operating on a normal FILTER cycle.
7. Adjust the valves in the skimmer and main drain lines (if provided) to achieve balanced flow rates.
8. When a pool is filled initially, the filter may have to be BACK WASHED once a day until the water becomes sparkling clear. From that point on, BACK WASH when pressure gauge indicates 30 to 40 kPa higher than at starting pressure.

OPERATIONAL & INSTALLATION TIPS

I. Always turn pump "OFF" before changing valve positions.
2. Never run pump dry as it depends on water for lubrication.
3. Always maintain minimum water level to 12 way up the skimmer mouth.
4. Clean pump strainer regularly.
5. Maintain a proper chemical balance in the pool.
6. Maximum operating pressure is 250kPa on FG Series
7. Ensure pressure gauge on valve is positioned so that rain water cannot collect on glass face.
8. Back wash filter regularly for 5 minutes each time to ensure sand is completely cleaned.
