____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.

5. GENERAL INFORMATION
The ‘Cartridge Filter’ combines superior water ltration with ease of operation and
totally corrosion-resistant construction. With ltration 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 lters utilize multiple reusable, reinforced polyester and anti-bacterial lter
cartridge elements to provide a high degree of water clarity and long lter cycles
with minimum care.

5.1 INSTALLATION
The lter system should be installed on a level concrete slab or other rigid base.
Select a well drained and vented area, one that does not ood when it rains.
Position the lter 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 lter will drain by gravity.
If practical, place the pump and lter 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 lter INLET.
Connect the lter OUTLET to the pool return plumbing lines.
Do not locate pump controls over or near the lter.
Verify water discharge from the Manual Air Relief Valve (MAR) is directed away
from electrical devices.
Use ONLY Original components; Non-Original Clamp components may fail in
use and cause explosive component separation. Verify that Upper and Lower
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)
Verify that the Filter Manual Air Relief Body is in the LOCK position, and no lter
components are missing, damaged or not genuine DuraTech components.
(See Fig 4)
Close lter drain. NOTE: Filter Plug requires an O-Ring seal. (See Fig 3)
Open all system valves to allow water from the pool to the ltration system and
from the lter to return to the pool.
Place the Manual Air Relief Valve in OPEN position. (See Fig 4)

6. OPERATION
____WARNING
Filtration starts as soon as ow is steady through the lter. As the lter removes dirt
from the pool water, the accumulated dirt causes a resistance to ow. As a result, the
gauge pressure will rise and the ow will decrease.
When the pressure rises between 0,49 - 0,69 bar (7 and 10 psi) above the starting
pressure, or when the ow decreases below the desired rate, clean or replace the
lter cartridge elements. Once your 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 lter cartridge elements.
By recording the initial starting pressure (with clean 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.
