After unboxing your pump, connect your hose to the pump. Place your pump wherein it would be easy for you to put the connection of the hose to the plunger valve. Get the two hoses of the pump and attach your hose's nuts to the pump. In a counter-clockwise direction, you need to unscrew the threaded filter housing collar from its filter housing. You must keep it safe in a secure place. Then, in a counter-clockwise direction again, turn both air release valves 1 to 2 turns to open it. Always do not remove air release valves as water would be released with force if the machine is turned on, and it could be hazardous. The next step is to check if your filter cartridges are placed correctly by lifting your pump's housing cover. Your sediment release valve must be tight. You could find it at the bottom of your pool pump's housing. Gently make it tight using your hand to ensure that water would not leak out. It's time to fill your pool with water first and once it is done, connect the hose from the bottom of the filter housing to the highest strainer assembly. You would always find the hose connection at the bottom of the plunger valve assembly. You need to connect the second hose which is fixed with the center of the motor housing, to the remaining line connection. It's now ready for the power cord of your Intex pool pump to be plug-in to a GFCI protected electrical outlet. You'll then turn both the plunger valve handles in a full counter-clockwise direction until they stop. This would open the valve, thus would allow the water to flow into the filter pump. There is a timer mode in all Intex Krystal Clear Cartridge Filter Pump. You could turn it on if you wish to. You could set it for the preferred operating hours of your pool filter pump. You could adjust this accordingly from time to time.
