CAUTION To reduce risk of injury, do not permit children to use or climb on this product. Closely supervise children at all times. The ANSI/NSPI-4 and EN16582 Standard (above-ground and on-ground pools) advises that components such as the filtration system, pumps, and heaters be positioned to prevent their being used as a means of access to the pool by young children.
WARNING COMPONENT SEPARATION HAZARD
Pool and spa water circulation systems operate under hazardous pressure during start up, normal operation, and possibly after pump shut off. Pressure in system can cause explosive component separation of the upper filter body if safety and operation instructions are not followed. Severe personal injury or death can result.
This product should be installed and serviced only by a qualified pool professional.

TO AVOID COMPONENT SEPARATION

• Follow all safety and operation instructions.
• Do not operate the water circulation system if a system component is assembled improperly, damaged, missing, or not a genuine component.
• Before performing maintenance on the water circulation system, verify all system and pump controls are in OFF position and the filter manual air relief valve is in the OPEN position.
• Use ONLY genuine components: Please use original components, otherwise may fail in use and cause explosive separation.
• Never rely on hand tightening the clamp nut to the clamp bolt.
• Using a ¾” socket on a torque wrench, torque clamp nut and clamp bolt to 17Nm (150 inch-lbs).
• Before starting the circulation pump, insure the Manual Air Relief Valve Body is properly installed onto the Upper Filter Body.
• Before starting the system pump, verify that all system valves are set in a position to allow water from the filter to return back to the pool.
• Before starting the system pump, the manual air relief valve must be in the OPEN position. Do this to remove air from the system.
• When starting the circulation pump, do not stand over or near the filter.
• If water leakage appears in the area of the filter tank clamp, immediately turn off all system circulation pumps and electrical power.
• Do not return to the filter until all water flow has stopped. Reassemble the clamp system per the instructions in this manual to stop the leak.
• See chapter: 9.4 LEAKING OF THE CLAMP
• Return to filter to close manual air relief valve only when a steady stream of water (Not air or air and water mix) is discharged from the manual air relief valve.
• Do not change the filter control valve position while system pump is running.

WARNING EXCESS PRESSURE HAZARD
Pressure testing of the pump and filter system in excess of the 3,45 Bar (50 PSI) can cause explosive separation of the components. Component separation can result in severe personal injury or death.
WARNING ELECTROCUTION HAZARD

• High Voltage electricity is present in the pool and spa equipment. High voltage electricity can cause shock and electrocution. Shock and electrocution can result in severe personal injury or death.
• All electrical wiring MUST be in conformance with applicable local codes and regulations.
• Before performing any service or maintenance on electrical equipment turn off all electrical power.
• Verify water discharge from the filter manual air relief valve is directed away from electrical devices. Do not locate any electrical controls over or near filter.

GENERAL INFORMATION

The ‘Cartridge Filter’ combines superior water filtration with ease of operation and totally corrosion-resistant construction. With filtration ratings to 34,000 liters (9000 gallons ) per hour, they are designed for continuous or intermittent operation, for installation above or below the pool water line, for fresh or salt water swimming pools or spa’s.
The filters utilize multiple reusable, reinforced polyester and anti-bacterial filter cartridge elements to provide a high degree of water clarity and long filter cycles with minimum care.

5.1 INSTALLATION
This product should be installed and serviced only by a qualified pool professional.
WARNING

Filter installation:

• The filter system should be installed on a level concrete slab or other rigid base.
• Select a well drained and vented area, one that does not flood when it rains.
• Position the filter so that the piping connections, and winter drain are convenient and accesible for operation, service, maintenance and winterizing.
• Position the Filter Body in such way that all operation and safety labels are visible.
• Position the Filter so that the filter will drain by gravity.
• If practical, place the pump and filter in the shade to shield it from continuous, direct heat from the sun.
• Connect the pool suction plumbing between the skimmer, pool suction outlet (from the pool) and the pump.
• Connect the pump discharge (pump OUTLET) to the filter INLET.
• Connect the filter OUTLET to the pool return plumbing lines.
• Do not locate pump controls over or near the filter.
• Verify water discharge from the Manual Air Relief Valve (MAR) is directed away from electrical devices.

5.2 STARTING THE PUMP AND FILTER SYSTEM
5.2.1 Before Starting The Pump
WARNING

1. Use ONLY Original components; Non-Original Clamp components may fail in use and cause explosive component separation. Verify that Upper and Lower
2. Filter Bodies are properly secured with the Filter Body Clamp. Never rely on hand tightening the Clamp Nut to the Clamp Bolt. Using a ¾” socket on a torque wrench, torque Clamp Nut to Clamp Bolt to 17Nm (150 inch-lbs). (See Fig 5)
3. Verify that the Filter Manual Air Relief Body is in the LOCK position, and no filter components are missing, damaged or not genuine DuraTech components. (See Fig 4)
4. Close filter drain. NOTE: Filter Plug requires an O-Ring seal. (See Fig 3)
5. Open all system valves to allow water from the pool to the filtration system and from the filter to return to the pool.
6. Place the Manual Air Relief Valve in OPEN position. (See Fig 4)

5.2.2 Starting The Pump

1. When starting system pump, do not stand over or near fi lter. If water leakage appears at fi lter tank clamp, immediately turn off all system circulation pumps and all electrical power. Do not return to the fi lter until all water leakage has stopped. Reassemble the Clamp System per the instructions on page 17 in this manual to stop leak. See chapter: 6.3.3 Body and Clamp Re-Assembly
2. When a steady stream of water (Not air or air and water mix) is discharged from the Manual Air Relief Valve, then close the Manual Air Relief Valve.

OPERATION

6.1 FILTERING
WARNING
Filtration starts as soon as fl ow is steady through the fi lter. As the fi lter removes dirt from the pool water, the accumulated dirt causes a resistance to fl ow. As a result, the gauge pressure will rise and the fl ow will decrease.
When the pressure rises between 0,49 – 0,69 bar (7 and 10 psi) above the starting pressure, or when the fl ow decreases below the desired rate, clean or replace the fi lter cartridge elements. Once your fi lter is running and there is a pressure reading, line up the green arrow with the current reading. (See Fig 6)
When the pressure rises to or above the red or second arrow, it is time to clean or replace your fi lter cartridge elements.
By recording the initial starting pressure (with clean fi lter elements) a determination can be made when the Filter Cartridge Elements should be replaced rather than cleaned. After the Filter Elements have been cleaned and reinstalled if the starting pressure is higher than 0,41 bar (6 PSI) above the starting pressure with the new Filter Cartridge Elements, the Filter Cartridge Elements should be replaced the next time the gauge arrow reaches the red arrow. 6.2 MAINTAINING YOUR FILTER
This product should be installed and serviced only by a qualified pool professional.
WARNING
