Powering the Filter Pump
It should be noted that the Pool Filter System does not have an on/off switch. Rather, power to the filter pump is connected and
disconnected by means of plugging in and unplugging the power cord from the power source. It is important that you read and follow
the instructions on proper power supply sources (see Section 5, Power Source Requirements) to avoid overloading the pump motor
and/or electric shock.
Sand & Initial Preparation
The Pool Filter System requires a specific type of sand (not included) for optimum operation: namely, silica sand with a particle size
of 0.45 mm - 0.55 mm. You can purchase this sand at most pool supply stores. While the sand will come packaged, it is important that
the sand be cleaned prior to running the filter system in filtration mode (see Section 9, Filter Operations).
Installation
Read and understand this manual carefully before installation. Failure to follow all instructions may result in electric shock, serious
personal injury or death.
