INSTALLATION, OPERATION & PARTS

CHAPTER 1:

IMPORTANT SAFETY INSTRUCTIONS

READ AND FOLLOW ALL INSTRUCTIONS

1. The sand lters are designed to work with water

temperature between 32ºF and 113ºF. The

lter should never be operated outside of these

temperatures or damage may occur.

2. The installation should be carried out in accordance

to the safety instructions of swimming pools and

the specic instructions for each facility.

3. The user should make sure that the installation is

carried out by qualied authorized persons and that

these persons have rst carefully read the following

instructions. Incorrectly installed equipment may

fail, causing sever injury or property damage.

4. The operating safety of the lter is only guaranteed if

the installation and operation instructions are

correctly followed.

5. To reduce the risk of injury, do not permit children

to use this product.

6. Chemical spills and fumes can weaken Swimming

Pool or Spa. Corrosion can cause lters and other

equipment to fail, resulting in severe injury or

property damage. Do not store pool chemicals near

your equipment.

7. Any modication of the lter is not authorized. The

supplier assumes no liability for the damage and

injuries caused by unauthorized replacement parts

and accessories.

Sand Filtration System Working Principle

Incoming water from the piping system is automatically

directed by the Multi-Port Valve to the top of the lter

bed. As the water is pumped through the lter sand,

dirt and debris are trapped by the lter bed, and ltered

out. The ltered water is returned from the bottom of

the lter tank, through the Multi-Port Valve and back

through the piping system.

CHAPTER 2: PREPARATION BEFORE INSTALL

▲WARNING This product should be installed and

 servicedonlybyaqualiedprofessional.

Position the lter next to the Swimming Pool or Spa.

2. The lter should be placed on a level concrete

slab, very rm ground, or equivalent. Ensure that

the ground will not subside, preventing any strain

from the attached plumbing.

3. Position the lter so that the piping connections,

Multi-Port Valve and winter drain is convenient and

accessible for operation, servicing and winterizing.

4. Ensure that the compliance label is facing the

front to allow easy identication in the case of

service difculties.

CHAPTER 3: INSTALLATION INSTRUCTIONS

1. Mount the pump to Sand Filter Support by using

the nuts and bolts.

2. Install the Drain Plug Assembly to the Sand Tank.

3. Mount Sand Tank to Sand Filter Support. Drain Plug

is on the outside.

4. Insert the Filter Assembly with Stand Pipe inside

the Sand Tank as pictured above. Then place the

Stand Pipe Blocker over the Sand Tank’s mouth

to prevent sand from getting into the Stand Pipe

and to keep the Stand Pipe in place. Then pour the

Silica Sand (41.8 lbs) into the Sand Tank.

5. Remove the Stand Pipe Blocker and clean the

Sand Tank neck carefully.

6. Connect the Multi-Port Valve to the Sand Tank by

using the O-Ring and the Flange Clamp Set. Note:

the direction of PUMP port on valve needs to face

pump out port.

7. Connect the Sand Tank to the Pump with Hose,

Hose Clamps and Hose Adaptors.

Plumbing

1. Make sure the lter is worked under the work

pressure and using a pressure control valve when

the system is using a booster pump.

2. If the pump position is higher than the water level,

it requires to install the back water control valve.

3. If the pump position is lower than the water level,

it requires installing an isolation valve. It could stop

the water return back when people do the general

inspection.

4. Minimize the length of pipe and the number of

ttings to minimize friction loss to ensure maximum

efciency.

5. Connect all plumbing to the Multi-Port Valve taking

care that all joints are glued or tightened securely

to prevent leaking.

6. To prevent breakage and damage to the pump and

Multi-Port Valve, use only pipe sealants specically

formulated for plastics.

7. Ensure solvents are not excessively applied to

ttings as this could run into O-Rings and create

sealing problems.

8. Do not over tighten ttings or adapters.

CHAPTER 3: MULTI-PORT VALVE OPERATION

1. Filter: Position for ltering the body of water.

Incoming water from the piping system is

automatically directed by the Multi-Port Valve to the

top of the lter bed. As the water is pumped through

the lter sand, dirt and debris are trapped by the

lter bed, and ltered out. The ltered water is

returned from the bottom of the lter tank, through

the Multi-Port Valve and back through the piping

system.

2. Backwash: Position for cleaning the lter media.

Water ow is reversed by the Multi-Port Valve

through the lter bed so that water ow is directed

to the bottom of the tank and up through the lter

bed, ushing the previously trapped dirt and debris

out the waste line.

3. Rinse: Position for ushing the lter system.

The water ow is directed by the Multi-Port Valve

through the lter bed and out the waste line. This

process settles the lter media bed into place and

ensures any dirt or debris is rinsed out of the lter,

preventing possible return to the Swimming Pool or Spa.

4. Waste: Position for bypassing the lter bed to

Waste. The water ow is directed by the Multi-Port

Valve straight to the backwash outlet, bypassing the

entire lter bed. This Multi-Port Valve position is used

to lower the water level or for vacuuming water with

high dirt loads.

CHAPTER 4: INITIAL STARTUP OF FILTER

Recheck that all the connections have been made

and are secure, and that the lter media was added

to the tank.

1. Depress Multi-Port Valve handle and rotate to the

BACKWASH position. NOTE: To prevent damage

to control valve seal, always depress handle

before turning.

2. Switch on the Pump. Open the Inlet Valve allowing

the Sand Tank to ll with water. CAUTION: All

suction and discharge valves must be open

when starting the pump. Failure to do so could

cause severe personal injury and/ or property

damage. NOTE: If a pump is installed, switch the

pump on and off, instead of closing and opening

the Inlet Valve.

3. Once water ow is steady out the waste line, run

the pump for at least one minute. The initial

backwashing of the lter is recommended to

remove any impurities or ne sand particles in the

lter media.

4. Turn the pump off. Set the Multi-Port Valve to the

RINSE position. Switch on the Pump. Open the

Inlet Valve until water in sight glass is clear -

approximately 10 to 15 seconds.

5. Switch off the Pump. Close the Inlet Valve, set the

Multi-Port Valve to the FILTER position and Switch

on the Pump. Open the Inlet. Your lter is now

operating in the normal lter mode.

6. Adjust pool suction and return valves to achieve

desired ow. Check the plumbing and lter for water

leaks and tighten connections, bolts, and nuts, as

required. NOTE: During initial clean-up of the

pool water, it may be necessary to backwash

frequently due to the unusually heavy initial dirt

load in the water.

7. Record the pressure gauge reading (start up

pressure) during initial operation. After a period

of time, the accumulated dirt and debris in the lter

causes a resistance to ow, and the ow diminishes.

The pressure will start to rise and the ow of

water will start diminishing. When the pressure

gauge reading is 8-10 PSI higher than the

initial “Start up” pressure, it is time to backwash

(clean) the lter (see Backwashing). NOTE: To

prevent unnecessary strain on piping system

and valving, always shut off the pump before

 switching lter control valve position. To

 prevent damage to the pump and lter and

for proper operation of they system, clean

pump strainer and skimmer baskets regularly.
