SEVERE CONDITIONS: If filter pressure increases a couple days after cleaning please contact
National Pools for further information, or replace with new filter cartridge.
DRAINING OF EXCESS WATER: Use hose adapter at bottom of filter.
- Cartridge Filter - To start filtering, make sure pump basket is full of water. Open bleeder
valve on top of filter, and open all valves on suction lines and discharge
lines. Start pump and tank will fill. When water begins to come out of
bleeder, close bleeder valve on pressure gauge. After closing the valve,
the unit has started its filtering cycle.
- Cartridge cleaning is recommended. Look under preventative maintaince category
for how often it should be cleaned. To clean the filter at the most ideal
time, note the pressure when the filter is perfectly clean. Then, when
the pressure rises approximately 10 PSI above the recorded pressure it
is time to clean, or every month, whichever comes first.
- To clean your cartridge, first shut off the pumpand open air bleeder. Then
remove locking nut and filter lid from filter housing. Remove cartridge
and clean with garden hose and high-pressure nozzle. Next, replace cartridge
in housing; lid and locking nut. Finally, close air bleeder and start pump.
NOTE: Always make sure the lid O ring is clean and lubricate every other
month with compatible lubricant.
- Skimmer Operation - To use your Pac Fab Skimmer, first you must vacuum pool and remove skimmer
basket. Secondly, assemble vacuum head, hose, and pole and place in pool.
Next, fill hose with pool water and insert hose end in the back of hole
of skimmer. Finally, turn on pump. When finished, reverse order of instruction
- The pump: Take the lid off the pump, remove strainer and empty. This should
be checked at least every two weeks. The lid is removed by unscrewing in
a counter clockwise direction. Lubricate O ring with silicone periodically.
- NOTE: Skimmer is controlled by three way Jandy valve when floor system is installed. Adjusted by National Pool representative. To drain pool below skimmer, please contact National Pools.
Pool Filter and Skimmer Operation
- This is one of the most important parts to keep your pool looking new.
With the test kit provided you will be able to test for chlorine and PH.
Any additional tests can be done at the pool supply store when you purchase
your chemicals. You should have it tested at least every other month for
cyanuric acid, total alkalinity, calcium hardness, and any other test your
pool supply store finds necessary.
- The chlorine should be kept at no less than 1.0 or more than 3.0 PPM according
to your test kit and .4-.5 PPM when a Vision system is installed. We will
gradually add chlorine to the water after the pool is full. We also add
stabilizer and calcium chloride if needed when we start up the filter system.
Balancing of the alkalinity reading is done over a period of weeks by adding
muriatic acid, which will be the responsibility of the homeowner.
- The PH should be maintained around 7.4-7.6 PPM on the test kit. Should your PH test out above 7.6 PPM, you will need to lower it by adding muriatic acid or dry acid depending on the alkalinity reading to the pool. This should be done with the pump running, adding 8 oz. to the deep end of the pool, away from any fixtures. Let the pump run for 1 hour and test PH again. If the PH is still high, add more acid accordingly until PH is in the proper range. Remember no more than 8 oz. of acid at a time. If the PH is low, (below 7.4 PPM), you will need to raise it by adding soda ash. You can purchase this at any pool supply store and the container will have instructions on how to use this chemical.
Chemicals and Balancing the pH level
- CAUTION ** READ CAREFULLY This chlorine dispenser is designed to use only slow eroding calcium based tablets. NEVER MIX WITH OTHER TYPES OF CHLORINE OR CHEMICALS. EXPLOSION OR FIRE MAY RESULT. Damage to filter and heating system will occur if TRICHLORO-S-TRIAZINETRIONE tablets are used.
- Exercise extreme caution when opening or servicing your dispenser. Always
shut off your pump. Do not inhale fumes from any chemical dispenser or
container. Protect your eyes, skin and clothing for chemicals at all times.
Always read label and follow chlorine manufacturer's and dealer's recommendations
for proper water conditioning and daily chlorine requirements for your
particular pool and area.
- Directions for use: Before start up of your chlorine dispenser, your pool/spa
should be properly conditioned and have a chlorine residual of approximately
1.0 to 1.5 PPM. Follow dealer and chemical manufacturer directions and
- The chlorine demand for pools and spas varies based on use, temperature, sunlight, etc. Initially, you'll have to experiment to determine the proper amount of chlorine and the correct adjustment required for your pool and filter time cycle. Using a 10,000-15,000 gallon pool as a guide, we suggest you place about 2 large eroding Sustain tablets in the tablet dispenser to increase or decrease the amount of chlorine. Check chlorine residual daily and adjust for proper level.
- Filter cleaning once a month in summer and once every other month in the
winter. This should take about eight hours total in the summer and four
hours total in the winter months.
- Your pool must be shocked or oxidized once a week in summer and once every
two weeks in the winter. When using the Sustain chemical program, summer
shield must be added every 5 months to help prevent algae.
- When using the Vision purification program oxidize pool once a week in summer and maintain proper levels of algaecide 60 to help prevent algae infestation. Please use non-chlorine shock when oxidizing pool. Replace Vision cartridge every 6 months.
- National Pools recommends that your chemical readings should fall in the
following ranges: Chlorine 1.5-3.0 (0.5-1.0 Vision) PH 7.4-7.6 Alkalinity
80-120 Cyanuric Acid 60-80 Calcium Hardness 200-400 Please retain all testing
records for future reference.
- ** DO NOT add chlorine or acid to pool water next to ladder or rail. Concentrated
chlorine, acid and stainless steel are not compatible. DO NOT expect rails/ladders
on indoor pools to react to chlorine the same as those outdoors. Due to
chlorine vapors trapped indoors, the tendency for discoloration of indoor
rail goods will be greater; therefore, the frequency of cleaning should
be increased. Regardless of environments, discoloration may occur if cleaning
is infrequent or not at all. We recommend occasional polishing with a cotton
type cloth to retain the original stainless luster. In the event of discoloration
or rust, a metal polish found in any auto or marine store will work very
- WARNING: Marcite finish will not be warranted for pitting, discoloration or etching. These conditions occur due to chemical imbalances in the water over short periods of time which National Pools has no control over. Some etching is normal due to the caustic nature of chlorine and acid. To help prevent staining, a metal sequestering agent should be maintained weekly at levels of 12-14 PPM.
- WARNING: It has been found, through recent studies, the use of stabilized base chlorine tablets causes an incorrect alkalinity reading. This discrepancy has contributed to some etching problems.
- Keep your pool and equipment clean. Vacuum pool and clean baskets at least
once a week. Any rubber O rings should be lubed every month with water
lube or compatible lubricant.
