Assembly

(You will need a screwdriver.)

A diagram showing a screwdriver icon next to a checkmark, indicating tools needed.

Carefully remove all components from the package and check to ensure nothing is damaged. If equipment is damaged, immediately notify the retailer from where the equipment was purchased.
The sand filter should be placed 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.
EN60335-2-41 TEST standard requires the sand filter to be vertically fixed on ground or a certain pedestal made of wood or concrete before use to prevent the sand filter from accidentally falling. Fully assembled sand filter will exceed 18kg. The mounting holes should be 8mm in diameter and spaced 86mm apart. Use two bolts and nuts with a maximum of 8mm in diameter to fasten the sand filter to the pedestal.

A series of diagrams illustrating the assembly process: 1. Unpacking and checking components. 2. Placing the sand filter on solid, level ground and securing it with bolts (showing bolt dimensions: Φ8mm diameter, 86mm spacing). 3. Adding pool-grade filter sand or Flowclear™ Polysphere into the tank, with a note to add water first to submerge the skimmer. The diagrams show the filter tank, the multi-port valve being attached, and sand being poured into the tank.

Load pool-grade filter sand/Flowclear™ Polysphere

NOTE: Use only special pool-grade filter sand, free of all limestone or clay: #20 Silica sand 0.45-0.85mm, approximately one 9kg bag should suffice. If you do not use the recommended size filter sand, filtering performance will be reduced and the sand filter may damaged, thereby voiding warranty.

NOTE: To avoid damaging the Skimmer when adding sand, pour some water into the Bottom Tank to submerse 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.

OPERATION

Timer

Plug into power source, adjust power switch to “ON” (-) position. The sand filter will begin working immediately.
Adjust power switch to “OFF” (0) position. The sand filter will stop working immediately.
After turning on, you can adjust work time, rest time and cycle time by turning the knob to desired position. See the table below for more details.
When the timer knob is moved into new position, the filter's previous cycle automatically cancels so new cycle can begin.
Each time the filter is powered on or restarted, a new cycle will begin based on timer knob position.

NOTE: If the knob is adjusted to the 24-hour position (24), the sand filter will work continuously without any rest period.

CONTROL VALVE OVERVIEW

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

How to Use the Control Valve:

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

A diagram of the multi-port control valve with a handle, indicating positions A, C, D, and an arrow showing rotation.

Control Valve Functions

Each function is illustrated with a simplified cross-section diagram of the sand filter, showing the direction of water flow (indicated by arrows) through the filter tank, multi-port valve, and connecting ports (A, B, C, D) for each specific operation.

Filter: This function is used to filter pool water and should be positioned here 99% of the time. Water is pumped through the sand filter, where it is cleaned and returned to the pool.
Closed: This function stops water flowing between the sand filter and the pool.
Backwash: This function is used to clean the sand bed; water is pumped down through the Collector Hub, upwards through the sand bed, and deposited out of Port D.
Rinse: This function for initial startup, cleaning, and sand bed leveling after Backwash; water is pumped downwards through the sand bed, up through the Collector Hub and deposited out of the valve Port D.
Drain: This function drains water from the pool; another filter bypass setting, water is pumped and deposited out of Port D, instead of returning it to the pool.
Circulate: This function circulates pool water bypassing the sand filter; use this function if the filter is broken to collect debris in the Debris Screens.

NOTE:

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 the Backwash, Rinse, or Drain position, water will discharge from Port D on the Control Valve.
Do not switch on or operate the sand filter with the Control Valve set to the Closed function or it will seriously damage the sand filter.
Do not set the Control Valve between two functions, or it will lead to leaking.
To avoid water leakage, screw the Port D Cap onto the Control Valve Port D before operating the filter or circulate function.

Air Release

Press down the control valve handle and wait until the water flow from Port D to release the air.

NOTE: It is important to repeat this operation every time you start the pump after winterizing, maintenance and 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

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

IMPORTANT: This procedure removes water from the pool, which you'll need to replace.

Switch off the sand filter immediately if water levels near the pool's Inlet and Outlet valves.

Two icons representing 'Backwash' (water flowing backwards) and 'Rinsing' (water flowing forwards with bubbles).

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.

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 take note of the filter pressure on Pressure Gauge. Generally, the recommended sand filter pressure is less than 0.45 Bar (6.5 PSI) when it is running.

A circular pressure gauge with markings from 0 to 1.6 Bar and 0 to 23 PSI, indicating normal operating pressure (less than 0.45 Bar / 6.5 PSI) and a higher pressure for maintenance (0.45 Bar / 6.5 PSI or higher).

Sand Filter Maintenance

CAUTION: You must ensure the sand filter is switched off and unplugged before any maintenance begins or severe risk of injury or death exists. As dirt builds up in the sand filter, the pressure reading on Pressure Gauge will increase. When the Pressure Gauge is 0.45 Bar (6.5 PSI) or higher, or water flow to the pool is too low, it is time to clean the sand. To clean the sand bed, follow all instructions outlined previously in: Backwash and Rinsing.

NOTE:

The Pressure Gauge is just used for measuring the water pressure, not used for precision measurement.
We recommend you clean the sand bed once a month or less regularly depending on how often the pool is used. Do not clean the sand too frequently.

Cleaning the Strainer

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

A series of three upward arrows pointing towards a diagram of the strainer basket, indicating the steps of removing, cleaning, and reinserting the strainer.

Lowering or Draining Pool Water

Switch off the sand filter and set Control Valve to the Drain function.
Detach the Hose from the pool's Port A and sand filter Port A and attach to Port D.

NOTE: Remember to replace the Debris Screen with Stopper Plug to prevent water from escaping.

Switch on the sand filter to remove pool water.

WARNING: DO NOT DRY RUN THE SAND FILTER.

Winterizing

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

Backwash the sand filter.
Drain the pool according to the pool owner's manual.
Unscrew the drain valve cap at the bottom of the tank and release the remaining water.
Disconnect the two Hoses from the pool and the sand filter.
Completely pour the sand out of the tank and dry all components.
Store the sand filter in a dry location out of child's reach.
