Assembly

You will need a screwdriver.

1. Carefully remove all components from the package and check for damage. Notify the retailer immediately if any equipment is damaged.
2. Place the sand filter on solid, level ground, preferably a concrete slab. Position the sand filter so the ports and Control Valve are accessible for operation, servicing, and winterizing.
3. The sand filter must be vertically fixed on the ground or a pedestal (made of wood or concrete) to prevent accidental falling, as per EN60335-2-41 TEST standard. The fully assembled sand filter exceeds 18kg. Mounting holes should be 8mm in diameter and spaced 285mm apart. Use two bolts and nuts (max 8mm diameter) to fasten the sand filter to the pedestal.
4. Load pool-grade filter sand/Flowclear™™ Polysphere.
   • NOTE: Use only special pool-grade filter sand, free of limestone or clay: #20 Silica sand 0.45-0.85mm, approximately one 8.5kg bag. Using incorrect sand may reduce filtering performance and damage the filter, voiding the warranty.
   • NOTE: To avoid damaging the Skimmer when adding sand, pour some water into the Bottom Tank to submerge the Skimmer on the Collector Hub.
   • NOTE: Sand/Flowclear™™ Polysphere not included.
   • NOTE: Use 28 g (0.06 lbs) Flowclear™™ Polysphere to replace 1 kg (2.20 lbs) sand.

Connect to the pool:

Operation

STOP: Before switching on, please read the manual carefully.

Control Valve Overview

WARNING: To prevent equipment damage and possible injury, always switch off the sand filter before changing the Control Valve function. Changing valve positions while the pump is running can damage the Control Valve, potentially causing personal injury or property damage.

How to Use the Control Valve: Press down on the Control Valve handle and rotate to the desired function.

Control Valve Functions

The Control Valve selects 6 different filter functions:

• Filter: Filters pool water. Water is pumped through the sand filter and returned to the pool. This function should be used 99% of the time.
• Closed: Stops water flow between the sand filter and the pool.
• Backwash: Cleans the sand bed. Water is pumped down through the Collector Hub, up through the sand bed, and out of Port D.
• Rinse: For initial startup, cleaning, and sand bed leveling after Backwash. Water is pumped downwards through the sand bed, up through the Collector Hub, and out of the valve Port D.
• Drain: Drains water from the pool. Water is pumped out of Port D instead of returning to the pool.
• Circulate: Circulates pool water, bypassing the sand filter. Use this function if the filter is broken to collect debris in the Debris Screens.

Notes on Operation

• Be sure all provisions for wastewater disposal meet applicable local, state, or national codes. Do not discharge water where it will cause flooding or damage.
• When the Control Valve is set to Backwash, Rinse, or Drain, water will discharge from Port D.
• Do not switch on or operate the sand filter with the Control Valve set to Closed, as this will seriously damage the sand filter.
• Do not set the Control Valve between two functions, as this will lead to leaking.
• To avoid water leakage, screw the Port D Cap onto the Control Valve Port D before operating the sand filter.

Air Release

Press down the control valve handle and wait until water flows from Port D to release the air. Repeat this operation every time you start the pump after winterizing, maintenance, or backwashing the sand bed.

First Time Use Instructions

Backwash and Rinsing must be performed to prepare the pump for its first use and to wash the sand.

CAUTION: DO NOT DRY RUN THE SAND FILTER

1. Press down on the Control Valve handle and rotate to the Backwash function.
2. Plug in and run the sand filter for 3-5 minutes, or until the water runs clear.
3. Switch off the sand filter and set the Control Valve to the Rinse function.
4. Switch on the sand filter and run for 1 minute. This circulates water backwards through the sand filter and drains water out of Port D.
5. Switch off the sand filter. Set the Control Valve to the Closed function.
6. Top up pool water if required.

IMPORTANT: This procedure removes water from the pool, which needs to be replaced. Switch off the sand filter immediately if water levels near the pool's Inlet and Outlet valves.

1. Now the sand filter is ready for use. Set the Control Valve to the Filter function.

NOTE: To prevent the risk of electrical shock, dry any excess water from yourself and the sand filter.

2. Switch on the sand filter to run it.

NOTE: The sand filter has now started its filtering cycle. Check that water is returning to the pool and note the filter pressure on the Pressure Gauge. Generally, the recommended sand filter pressure is less than 0.25Bar (3.5PSI) when running.

Sand Filter Maintenance

CAUTION: Ensure the sand filter is switched off and unplugged before any maintenance. Failure to do so can result in severe injury or death.

As dirt builds up in the sand filter, the pressure reading on the Pressure Gauge will increase. When the Pressure Gauge reads 0.25Bar (3.5PSI) or higher, or water flow to the pool is too low, it is time to clean the sand.

To clean the sand bed, follow the instructions outlined previously in: Backwash and Rinsing.

NOTE: Pressure gauge is for maintenance purposes only and the pressure gauge value is for reference; it should not be used as a precision instrument.

NOTE: Clean the sand bed once a month or less regularly depending on pool usage. Do not clean the sand too frequently.

Cleaning the Strainer

1. Switch off the sand filter and set the Control Valve to the Closed function.
2. Replace the Debris Screens with Stopper Plugs to prevent water from escaping.
3. Remove the Strainer Cover by unscrewing it.
4. Take out the Strainer and remove any debris.
5. Put the Strainer back into position, ensuring the hole in the strainer is aligned.
6. Ensure the Seal Ring is in place. Secure the Strainer Cover back.
7. Remove the Stopper Plugs and insert the Debris Screens.

NOTE: The Strainer must be emptied and cleaned periodically. A dirty or blocked strainer will reduce the performance of the sand filter.

Lowering or Draining Pool Water

1. Switch off the sand filter and set the Control Valve to the Drain function.
2. Detach the Hose from the pool's Port A and sand filter Port A, and attach it to Port D.
3. NOTE: Remember to replace the Debris Screen with a Stopper Plug to prevent water from escaping.
4. Switch on the sand filter to run the filter and remove the pool water.

WARNING: DO NOT DRY RUN THE SAND FILTER.

Winterizing

In areas with freezing winter temperatures, pool equipment must be winterized to protect against damage. Allowing water to freeze will damage the sand filter and void the warranty.

1. Backwash the sand filter.
2. Drain the pool according to the pool owner's manual.
3. Disconnect the two Hoses from the pool and the sand filter.
4. Completely pour the sand out of the tank and dry all components.
5. Store the sand filter in a dry location out of children's reach.
