Multi-Port Valve Operation

1. Filter - Position for filtering the body of water.

Incoming water from the piping system is automatically

directed by the Multi-Port Valve to the top of the filter

bed. As the water is pumped through the filter sand, dirt

and debris are trapped by the filter bed, and filtered out.

The filtered water is returned from the bottom of the filter

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

piping system.

2. Backwash - Position for cleaning the filter media.

Water flow is reversed by the Multi-Port Valve through

the filter bed so that water flow is directed to the bottom

of the tank and up through the filter bed, flushing the

previously trapped dirt and debris out the waste line.

3. Rinse - Position for flushing the filter system.

The water flow is directed by the Multi-Port Valve through

the filter bed and out the waste line. This process settles

the filter media bed into place and ensures any dirt or

debris is rinsed out of the filter, preventing possible return

to the Swimming Pool.

4. Waste - Position for bypassing the filter bed to Waste.

The water flow is directed by the Multi-Port Valve straight

to the backwash outlet, bypassing the entire filter bed.

This Multi-Port Valve position is used lower the water level

or for vacuuming water with high dirt loads.

5. Re-circulate - Position for bypassing the filter bed to

the Swimming Pool.

The Multi-Port valve recirculates water flow directly back

to the Swimming Pool, bypassing the filter.

6. Closed – Position for closing all flow to the filter.

This position is not to be used with the pump operating.

CAUTION: Operation of the Multi-Port Valve or

mode selection is to be always done with the pump

switched off.

Initial Startup of Filter

NOTE: See Pump Owners Manual For Operation

Instructions Before Starting System. To prevent damage

to the pump and filter and for proper operation of the

system, clean pump strainer and skimmer baskets

regularly.

Be sure correct amount of filter sand media is in tank and

that all connections have been made and are secure.

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

filter tank to fill 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 flow is steady out the waste line, run the

pump for at least 1 minute. The initial backwashing of the

filter is recommended to remove any impurities or fine

sand particles in the sand media.

4. Turn the pump off, 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 filter is now operating in the normal

filter mode.

6. Adjust pool suction and return valves to achieve desired

flow. Check the plumbing and filter 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 filter causes a

resistance to flow, and the flow diminishes. The

pressure will start to rise and the flow of water will start

diminishing. When the pressure gauge reading is 10psi

higher than the initial "Start up" pressure, it is time to

backwash (clean) the filter (see Backwashing).
