FILTER PUMP HOSE CONNECTION SETUP

1. Remove the Krystal Clear filter pump and hoses from the packaging.
2. Place the filter pump in such a manner, that you can easily assemble the hose (8) connections to the plunger valve.
   Note: Some regional regulations may require the filter pump to be mounted on a stationary platform. There are two mounting holes located in the pump base for this reason. Consult your local authorities for filter-pump mounting requirements.
3. Grasp the two pump hoses (8) and connect the hose nuts to the filter pump.
4. In a counter-clockwise motion unscrew the threaded filter housing collar (1) from the filter housing. Place it in a safe place.
5. The Filter Pump is an airtight system. In a counter-clockwise motion turn both air release valves (2 & 7) 1 - 2 turns to open.
   DO NOT remove air release valves as water will expel with force if the motor is turned on and injury may occur.
6. Grasp and remove the filter housing cover (4). Check to see if a cartridge is  inside the housing. If yes, replace the cover, finger tighten the housing collar (1) back onto the filter housing.
7. Gently finger tighten the sediment release valve located at the bottom  of the  housing to be sure that water does not leak out.
8. When the pool is filled connect the hose from the bottom of the filter housing to the highest strainer assembly. You will find the hose connection at the bottom of the plunger valve assembly. Use the hose nut to attach the hose.
9. Connect the second hose which is fixed to the middle of the motor housing to the remaining liner connection.

WARNING

Position this product away from the pool, so as to prevent children from climbing on it and accessing the pool.

OPERATING INSTRUCTIONS

1. Make sure the filter pump is switched off. The switch is located on the motor housing.
2. Connect the power cord to a GFCI protected electrical outlet.
   WARNING: Risk of electric shock. Connect this product only to a grounding type receptacle protected by a ground-fault circuit interrupter (GFCI). Contact a qualified electrician if you cannot verify that the receptacle is protected by a GFCI.
   IMPORTANT: To prevent air lock, open the lower plunger valve (connected inlet hose) first and then the upper plunger valve (connected outlet hose). Open the air release valve, wait until water starts to flow out of the air release valve, close air release valve.
3. Turn both plunger valve handles fully counter-clockwise until they stop. This opens the valve, allowing water to flow into the filter pump.
4. With water flowing into filter pump, the water pressure will allow the air trapped inside to escape from the air release valves (2 & 7). When all the air has escaped water will flow out of the valves (2 & 7). When this occurs gently finger tighten the valves (2 & 7) in a clockwise direction.
   NOTE: The plunger valve is equipped with a vacuum release valve that will automatically activate to minimize the suction at the pool outlet if the outlet is blocked. This is an additional safety feature to prevent suction entrapment. The vacuum release valve will reset once the blockage is removed and the pump is switched off. To restart the system the air must be removed from the filter pump per previous step.

5. To operate the filter pump on “TIMER” mode:

   1. Set the timer dial to the desired operating hours. See operation time table. See Fig. 10
   2. Turn on the pump by pressing the switch to “    ” position, the filter pump is now filtering the water and will stop after the operating hours are completed. The built-in timer will now operate for the number of hours selected at the same time each day.
   3. Operating hours can be re-adjusted if necessary. Follow step A – B.

   To operate the filter pump manually (without the “TIMER” mode):

   1. Turn on the pump by pressing the switch to “I” position, the filter pump is now filtering the water.

   2. To turn off the pump, press the switch to “O” position.

      

OPERATING TIME TABLE

POOL CARE AND CHEMICALS 

• All pools require care to keep the water clear and hygienically clean. With proper chemical control, your filter will help attain this objective. Consult your pool supply dealer for instructions regarding the proper use of chlorine, algaecide and other chemical agents required for sparkling clear water.
• Keep pool chemicals away from children.
• Do not replenish chemicals in pool while pool is occupied. Skin or eye irritations could occur.
• Daily pH checking and chemical treatment of the water is very important and can not be overemphasized. Chlorine, algaecide and maintenance of proper pH levels are required when filling the pool as well as during the season. Consult your local swimming pool supply store for instructions.
• The season's first filling of the pool may have brackish water requiring extra water additives and extra filter changes. Do not allow swimming in pool until the pH level is balanced. Consult your local swimming pool supply store for instructions.
• Keep spare filter cartridges on hand. Replace cartridges every two weeks.
• Chlorinated water may damage lawns, gardens or shrubbery as children play in the pool and splash water outside the pool. Lawn areas underneath the pool liner will be destroyed. Note that some types of grass may grow through the liner.
• Filter run time depends on pool size, weather and usage level. Experiment with various run times so as to produce clean clear water.

CAUTION

Concentrated chlorine solutions may damage the pool liner. Always follow the chemical manufacturer’s directions, and the health and hazard warnings.
