SPECIFICATIONS

PARTS REFERENCE OVERVIEW

Before assembling the sand filter, take a few minutes to become familiar with all the sand filter parts.

ASSEMBLY

(You will need a screwdriver.)

1. 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.
2. 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.
3. 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 18 kg. The mounting holes should be 8 mm in diameter and spaced 86 mm apart. Use two bolts and nuts with a maximum of 8 mm in diameter to fasten the sand filter to the pedestal.

IMPORTANT: Do not place chlorine in the strainer to avoid damaging the sand filter.
LOAD POOL-GRADE FILTER SAND/POLYSPHERE™ POOL FILTRATION BALLS.
NOTE: Use only special pool-grade filter sand, free of all limestone or clay: #20 Silica sand 0.45-0.85 mm, approximately one 9 kg bag should suffice.
If you do not use the recommended size of filter sand, filtering performance will be reduced and the sand filter may damaged, thereby voiding the warranty.
IMPORTANT: We suggest using #20 silica sand with your pool sand filter. It is specially graded to trap particles in the 20 – 100 micron range. Some small debris can pass throw the sand and back into the pool. This is normal, especially if the debris is fine or silt. To limit this, it is better to follow the maintenance instructions, and backwash and rinse when necessary.
We also suggest contacting your pool dealer for the chemical product specifically made to clean the sand. The correct maintenance of the sand will optimize the cleaning efficiency and avoid accumulation of oils or scale.
When you are vacuuming the bottom of the pool that has a large amount of debris, we suggest to backwash the sand when you finish cleaning half of the pool.
Remember to backwash and rinse the sand after vacuuming the bottom of the pool each time.
NOTE: To avoid damaging the Skimmer when adding sand, pour some water into the Bottom Tank to submerse the Skimmer on the Hub.
NOTE: Sand/Polysphere™ Pool Filtration Balls not included.
NOTE: Use 28 g (0.06 lbs) Polysphere™ Pool Filtration Balls to replace 1 kg (2.20 lbs) sand.

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.

CONTROL VALVE FUNCTIONS
The Control valve is used to select 6 different filter functions: Filter, Closed, Backwash, Rinse, Drain and Circulate.

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 by passing 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 sand filter.

AIR RELEASE
Press down the control valve handle and wait untill 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

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 the sand filter for 1 min. This circulates water backwards through the sand filter and drains water out 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 you’ll need to replace. 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 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.

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

1. Switch off the sand filter and set the Control Valve to the Closed function.
2. Close the connection valves.
3. Remove the Strainer Cover by unscrewing it.
4. Take out the Strainer, remove any debris.
5. Put the Strainer back into position. Ensure the hole in the strainer is aligned.
6. Ensure the Seal Ring is in place. Secure the Strainer Cover back.
7. Open the connection valves.
   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. Backwash the sand filter.

2. 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.

3. Switch on the sand filter to remove pool water.
   WARNING: DO NOT DRY RUN THE SAND FILTER.

STORAGE

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.

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