FILTER SYSTEM OWNER’S MANUAL

GENERAL DESCRIPTION

Crystal Water / Aqua Clean Cartridge Filters are high performance swimming pool and spa filters manufactured from durable, corrosion-proof Thermoplastic. They are designed for continuous or intermittent operation, for installation above or below the pool water line, and for fresh or salt water swimming pools or spas. Crystal Water / Aqua Clean Cartridge Filters utilize multiple reusable, reinforced polyester filter cartridge elements to provide a high degree of water clarity and long filter cycles with absolute minimum care.

INSTALLATION INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS READ AND FOLLOW ALL INSTRUCTIONS
A). When installing and using this equipment, basic safety precautions must always be followed. This filter operates under high pressure. Failure to follow instructions may result in serious injury.
B). Make sure clamp is located properly over the filter flange. The clamp must be tightened firmly and never rely on hand tightening the clamp nut to the clamp bolt. Using a 3/4” socket on a torque wrench, torque clamp nut and clamp bolt to 216 inch/lbs.(see illustration step 20, page 9).
C) . CAUTION: All suction and discharge valves must be open when starting the system. Failure to do so could result in severe personal injury and/or property damage.
WARNING: This product should be installed and serviced by a qualified professional only

1. PUMP SELECTION AND LOCATION:
   To power your filter, select a continuous duty pump designed for swimming pool or spa service.
   It is important to first determine where your pump and filter will be located. If above the water line, a self-priming pump has the ability to lift water from a lower level and prime automatically. Select a pump with an average output range suitable for the filters capacity. Other considerations are operation of hydrotherapy fittings, automatic cleaners, etc. Your dealer will help you select the proper size pump for your system.

2. FILTER LOCATION:
Since plumbing fittings offer a resistance to water flow, position the filter as close to the swimming pool as practical. Keep the number of fittings to a minimum. Select a welldrained area, one that will not flood when it rains. The filter should be placed on a level concrete slab, very firm ground or equivalent, as recommended by your pool dealer. Allow for minimum top and side clearances as per chart. Be sure filter, pump, drain and pressure gauge are accessible for convenient operation. Position filter so the tank can drain away from pool and buildings by gravity. If practical, place pump and filter in the shade to shield it from continuous direct heat from sun.

3. PLUMBING:
   Use 1 1/2″, 2″ or 2 1/2″ piping. Connections are 2″ slip (solvent weld).

4. Ball or gate valves are recommended where needed. While all systems vary, the main consideration is to provide the desired control of water flow from the pool to the pump, to the filter and back to the pool. When the filter is located  below the water level, provide valves to prevent back flow of water to the filter during cleaning and routine servicing.

5. Connect the pool skimmer(s) and main drain(s) to the inlet and the return lines to the outlet of the filter. Always use two or more drains per pump.
   If pressure gauge is not already installed, apply Teflon tape to the gauge threads on the heavy duty manual air relief valve (MAR), and carefully screw the gauge into the gauge adapter assembly.
   DO NOT OVER TIGHTEN.

6. A filter drain plug is furnished with each filter and is all that is needed for complete filter draining. A Heavy Duty Manual Air Relief Valve (MAR) is furnished to aid in bleeding unwanted air when starting the filter. The internal auto  air vent provides air removal during operation.

7. CAUTION: ANSI/ NSPI-4 Article V, standard for in-ground pools, advises that components such as the filtration system, pumps and heater be positioned so as to prevent access by young children.

8. All electrical connections should be made in accordance with local codes.

9. BEFORE STARTING THE FILTER:
   Obtain a supply of operating chemicals and a pool test kit. Balance the pool water by adding chemicals in accordance with the instructions provided by the chemicals’ manufacturer.
   WARNING

10. AFTER EACH SERVICE OR INITIAL INSTALLATION, BEFORE STARTING THE PUMP:
    Verify the filter body clamp is properly assembled, and no filter components are missing, damaged  or not genuine Waterway components. Close filter drain. Open all system valves to allow normal  system operation. Place the Heavy Duty Manual Air Relief Valve in the OPEN position (as shown in  the picture). Stand at least 10 feet clear from filter before starting the pump. Follow the manufacturer’s instructions to prime and start the pump. Return to  filter to close the heavy duty  manual air relief valve only when a steady stream of water (not air or, air and water mix) is  discharged from the heavy duty manual air relief valve.

11. PRESSURE GAUGE:
    As the filter removes dirt from the pool water, the accumulated dirt causes a resistance to flow. As a result, the pressure gauge will rise and the flow will decrease. When the pressure rises 8-10 psi above the start (clean) pressure, it is  time to clean the filter(s).
    NOTE: During initial clean-up of the pool, particularly with a new pool or a very dirty pool, it may be necessary to clean more frequently due to the unusually heavy initial dirt load in the water.

12. TO CLEAN/REPLACE CARTRIDGES:
    Before Removing Cartridge Elements: Shut off pump. If filter is located below water level, close valves (or block off suction and discharge lines) to prevent backflow of water from pool.

13. Unscrew and remove drain plug and allow water to drain from filter. Be sure to reinstall the drain plug before refilling filter. NOTE: To assist drainage process, open Manual Air Relief assembly (MAR) on top of tank a few turns.

14. DISASSEMBLY:
    Shut off the pump then use a 3/4” deep socket and ratchet (1) to remove Clamp Brass Nut. Place clamp assembly out of the way in a convenient place (2). You can now easily remove the filter lid, exposing the dirty element assembly.
    Damage to clamp may lead to system failure.

15. TO REMOVE CARTRIDGES:
    Remove Plug, Cartridge Manifold.
    Remove cartridges from bottom Cartridge Manifold Assembly by using a slight rocking motion and lifting up. Clean cartridge.

16. CLEANING CARTRIDGES:
    The cartridge filter element can be cleaned by pressure washing inside and outside with a garden hose. After hosing the cartridge, for best results, allow cartridge to dry and then using a stiff nylon brush, carefully brush pleated surface areas to remove fine particles.

17. You may find some debris on the cartridge pleats, which may have not been removed with hosing. In such a case, soak the cartridge in a solution of filter element cleaner (found at pool dealers). Follow manufacturer’s directions for  use. Hose thoroughly before reinstalling the cartridge in the filter.
    If calcium or mineral deposits are found, clean cartridge by soaking in a plastic container with muriatic acid added to water with a 1 to 10 ratio. Always use caution when handling muriatic acid. After cleaning, flush with water.

18. REINSTALLING CARTRIDGES:
    Flush and drain any dirt or debris from the bottom of the filter tank.
    Carefully replace cartridges over bottom Cartridge Manifold Assembly.
    Place Cartridge Manifold Plug securely into top of cartridges.

19. REINSTALL TANK LID:
    Clean and lightly lubricate O-Ring with silicone lubricant.
    Clean O-Ring flange sealing surface on filter lid and place over bottom tank O-Ring, pressing down firmly and evenly to seat the filter lid in place.

20. THESE INSTRUCTIONS MUST BE FOLLOWED EXACTLY TO PREVENT THE LID FROM BLOWING OFF DURING SYSTEM STARTUP.
    1. Be certain the O-Ring is in position in the lower tank half. Place the filter lid over the lower tank half, sandwiching the O-Ring in between.
    2. Use only Waterway clamp system components, nut/bolt assembly and seal. Non Waterway clamp system components may fail in use and cause sudden component separation.
    3. Verify that upper and lower filter bodies are properly secured with the filter body clamp.
    4. Never rely on hand tightening the clamp nut to the clamp bolt. Using a 3/4” socket on a torque wrench, torque clamp nut to clamp bolt to 216 inch/lbs.
    5. Verify that the manual air relief valve is secured onto the filter lid and no filter components are missing, damaged or not genuine Waterway components. Never tap the clamp with a mallet or similar objects.

21. Install drain plug, open pool suction and return valves and proceed as in INITIAL START-UP OF THE FILTER, step 10, page 5.

22. WINTERIZING:
    To winterize where sub-freezing temperatures can be expected, the filter should be drained. Remove and clean cartridges. Reinstall cartridges in filter tank.
    Be sure to remove the drain plug during the winter season to avoid cracking the filter tank.

IMPORTANT INFORMATION:

Read and Follow All Instructions:
Algae is a form of plant life which can vary in size from a few thousandths of an inch to the size of a small tree. Of the many forms of algae, the one most frequently found in the swimming pool water are microscopic in size and green in color.
Algae readily grows in sunlight and can, under favorable conditions, quickly overgrow a swimming pool, turning it completely green in just a few hours. On the other hand, swimming pool water can be unfavorable to algae growth simply by maintaining a chlorine level of at least 1.0 ppm in the water at all times. The chlorine level should be checked at least once a week using a suitable test kit.
If an algae condition develops and the pool water “blooms” green, super chlorination of the pool will be necessary to clear it. Add unsterilized granular chlorine or liquid chlorine.
Follow the chemical manufacturer’s recommendation for super chlorination. The algae will quickly become inactive and can then be removed by the filter. Live algae, on the other hand, multiplies so fast that the filter cannot keep up with  its growth rate. When correctly used, commercial algaecides are effective against algae, though algaecides should be used in conjunction with, and not as a substitute for, regular chlorination or super chlorination.
Maintaining a chlorine level of at least 1.0 ppm in the pool water at all times is the most effective way to prevent algae growth in swimming pools.
NOTE:
Pure clear swimming pool water is the combination of two factors: adequate filtration and proper water chemistry balance. One without the other will not give the clean, clear water you desire.
Your filter system is designed for continuous operation. However, this is not necessary for most swimming pools. You can determine your filter operation schedule based on your pool size.
To properly sanitize your pool, maintaining a free chlorine level of 1 to 3 ppm and a pH level of 7.6 will help in preventing algae and bacteria to grow in your pool and make it easier for your filter to properly clean the pool water.
SERVICE AND REPAIRS:
Consult your local authorized Waterway dealer or service center. No returns may be made directly to the factory without the expressed written authorization of Waterway Plastics.

GENERAL POOL CHEMISTRY GUIDELINES

To properly sanitize your pool, maintain a chlorine level of 1 to 3 ppm and a pH of 7.2 to 7.6. Insufficient chlorine or an out of balance pH level will permit algae and bacteria to grow in your pool and make it difficult for your filter to  properly clean the pool water.
