ECA SERIES MEDIA FILTERS

GENERAL NOTES

1. 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.

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

5. Installation of filters and pumps should be located as close to the pool as possible to avoid excessive piping friction

6. If system is installed below pool level it is important to install isolating valves to prevent risk of flooding from back

7. The proper sand selection is critical to good filter performance. Ensure that the media is an approved form of

8. The installation of filters requires no special tools.

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”).

LOADING FILTER SAND

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

1. Check filter size in order to determine necessary amount of sand 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 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 sand loading procedure to
ensure alignment with valve assembly opening.

5. Proceed to load correct volume of dry sand slowly (if sand is saturated loading can be difficult).

6. Once sand is loaded discard loading disc and check to determine if stand pipe is properly centered in tank opening.

7. Fill with sand, glass or other approved sand to the shoulder level of the filter.

INSTALLATION OF SELECTOR VALVE

1. Following the sand loading, clean any sand particles or debris from upper surface of tank opening.

2. Install six (6) position selector valve after placing O-Ring in cavity on tank 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.
a. CA Series: once valve positioned, tighten the lock ring firmly by hand.
b. ECA Series: once valve positioned, fit clamp band assembly around neck of filter and valve and tighten

sufficiently for good engagement.

c. Note: It is not necessary to over tighten.

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 Astral Pool barrel unions

supplied with the filter. 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 plug from side wall of valve and install threaded pressure gauge (if not already fitted) using Teflon tape

wrap. Do not over tighten. Minimal hand tightening is adequate to provide a good seal.

NOTE:

How to correct a liquid filled gauge that has moved off of “0 psi” during shipping?

Why it happens

Liquid filled pressure and vacuum gauges are tested for accuracy at the factory. However, during transport,

changes in temperature and altitude may cause a shift in the gauge’s internal pressure. That, in turn, causes the

gauge’s resting point to change. There are no long term side effects from these changes if the gauge is vented to

equalize that pressure.
If the gauge is placed in a location where big temperature changes are common, you may want to vent it when
major changes occur. When installing new gauges, it is a good practice to mount them with the stopper up so that
they can be vented easily

How to fix it

On top of the gauge is a rubber stopper which secures the liquid filling. To calibrate a gauge that is not returning to
zero, just lift one edge of the stopper to equalize the pressure inside. Try to position the gauge so that the stopper
opening is pointed upward and any air bubble inside the pressure gauge is at the near it. After venting the gauge,
you should see the pointer move back to 0 psi, remember to keep the gauge vertical (stopper on top), so that the
oil doesn't leak out.
If a little of the liquid escapes, just wipe it away. Astralpool uses non-toxic food grade glycerin to fill its gauges.
Wiping away the excess is important however, as left over glycerin will collect dust and debris if it is not cleaned
off. Replace the stopper when finished. The gauge will work without stopper replacement, but it should be put back
in place to maintain a clear dial. An open top will allow dust and debris into the casing, which could cloud the
readout and might damage the gauge over time.

VALVE OPERATION

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 levelling 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 bi­passes the filter and is used for circulation of pool water
only.

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

NOTE: Always “STOP” pump when changing selector valve position.

INITIAL START - UP

1. Make sure the correct amount of sand 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

sand.

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

1. 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 ½ 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 CA Series and 200 kPa on ECA Series.

7. Ensure pressure gauge on valve is positioned so that rain water cannot collect on glass face.

8. Back wash filter regularly for 3-5 minutes or until sight glass runs clean each time to ensure sand is completely

cleaned.

9. Always rinse for 1 minute after each backwash and before returning valve position to filter.

Maintenance of your filter

Timing

Maintenance Check

Service action (if required)

Fortnightly

Check pressure gauge. If pressure increase is
greater than 20kPa cleaning may be required

Perform backwash according to instructions

Three Monthly

Check inlet/outlet o’rings for leaks

Isolate Pump, turn power off, clean and
grease O rings or replace if necessary

Annually

Compare operating pressure of backwashed
filter to initial pressure (when new)
If using Zeolite or M3, regenerate filter sand.
This is important in commercial applications as
it aids in the removal of ammonias.

If pressure is more than 30 – 40 kPa different
from new filter, a sand change may be
required
Add salt to filter sand per supplier. Allow to
sit for 24 hours then backwash, rinse and
return to filter.
