Section I. HOW Your Pump Works

WARNING

To reduce the risk of electrical shock, do not use an extension cord to connect unit to electric supply; provide a properly located outlet.

WARNING

For continued protection against possible electrical shock, this unit is to be mounted to the base in accordance with the installation instructions.

Important Notice

This pump operates with electrical voltage, and can generate both vacuum and pressure in the water system. When properly wired and plumbed, this pump will operate in a safe manner.

CAUTION

This pump is for use with permanently installed pools and may also be used with hot tubs and spas. Do not use with storable pools unless pump is protected by factory installed double insulated enclosure. A permanently installed pool is constructed in or on the ground or in a building such that it cannot be readily disassembled for storage. A storable pool is constructed so that it may be readily disassembled for storage and reassembled to its original integrity and has a maximum dimension of 18 feet and a maximum wall height of 42 inches.

READ AND FOLLOW ALL SAFETY INSTRUCTIONS

Your centrifugal pump is designed to operate for years with proper maintenance. The pump housing, seal plate, hair and lint pot and impeller are made from high quality thermoplastic materials. These materials have been selected for their corrosion resistance nature. When installed, operated and maintained in accordance with these instructions, your pump will provide years of service.

Your centrifugal pump is driven by an electric motor. The motor is directly attached to the pump impeller. As the electric motor turns it causes the impeller to turn and this causes the water to flow. The water flows into the hair and lint pot inlet and through the basket assembly to pre-strain large particles. The flow then enters the center of the pump housing. If the pump does not contain the hair and lint pot assembly, the flow simply enters the center of the pump housing. The flow goes through the impeller and out the pump discharge port.

2-Speed Pump Models:

The performance of this pump will be the same at high speed as the same model single speed pump, hydraulically. At low speed the pump will produce one half the flow and 1/4 the pressure of high speed. However, the pressure required by the filter and pool plumbing at half flow will also be greatly reduced due to much lower system friction. These lower friction losses result in GREAT energy savings. At one half flow (low speed) the electrical energy savings are 60% for equal amounts of circulated water.

Turn the motor to low speed for quiet operation and electrical cost savings. Since the pump should be operated mostly at low speed for cost savings, minor adjustments may be required in the automatic chlorine dispenser, the skimmers and the heater due to the lower flow. (See the equipment manufacturer’s operation manuals.)

Pool owners should use high speed for vacuuming the pool, quick filtering action, priming the system, and to keep up with heavy bathing loads.

SECTION II. INSTALLATION

1.Check carton for any evidence of damage due to rough handling in shipment. If carton or any pump components are damaged, notify freight carrier immediately.

2.After inspection, carefully remove pump from carton.

3.The pump should be secured to a flat solid foundation, high enough to prevent flooding of the motor. A sheltered location is best, being sure to allow for adequate ventilation.
