4.Provide space and lighting for routine maintenance access. Do not mount electrical controls directly over pump.

5.The pump should be installed as near to the pool or spa as practical. Avoid installing the pump above the water level. Suction lifts of more than 1/2 foot will cause very long priming times, and potentially damage the pump.

6.The location should provide for adequate floor drainage to prevent flooding.

7.When installing your pump, remember to provide valves or other means to disconnect the pump suction and discharge for servicing.

8.Never store pool chemicals within 10 ft. of your pool filter and pump. Pool chemicals are corrosive and should always be stored in a cool, dry, well ventilated area.

WARNING

Chemical fumes and/or spills can cause severe corrosive attack to the filter and pump structural components. Structurally weakened filter or pump components can cause filter, pump or valve attachments to blow off and could cause severe bodily injury or property damage.

9.Assemble piping and pipe fittings to pump and valve. All piping must conform to local and state plumbing and sanitary codes.

10.Use Teflon tape or pipe sealants on all male connections of pipe and fittings. Use only pipe sealant compounds suited for plastic pipe. Support pipe to prevent strains on filter, pump or valve. DO NOT USE PETROLEUM BASED PRODUCTS.

11.Avoid over tightening the pipe threads when connecting fittings to the pump. Proper procedure is to apply a pipe sealant to the thread and then install hand tight plus 1 1/2 turns. DO NOT OVER TIGHTEN.

12.Long piping runs and elbows restrict flow. For best efficiency use the fewest possible fittings, large diameter pipe (at least 1 1/2”) & locate equipment as close to the pool as possible. The pump suction line should not be smaller than the pipe size on the inlet of the pump.

13 It is essential that the suction line be free of air leaks and air traps.

WARNING

Blockage of suction fittings can cause severe or fatal injury due to drowning. Small children using pool/spa equipment must always have close adult supervision.

14.Suction fittings must conform to ASME/ANSI A 112.19.8 M Standards. Use double suction fittings.

15.The maximum operating pressure of this unit is 25 pounds per square inch. Never operate this pump above this pressure.

This pump is not intended to be operated in series with other pumps.

WARNING

To reduce the risk of injury, do not permit children to use this product unless they are closely supervised at all times.

16.Wiring of this pump should be performed by a licensed electrician in accordance with the National Electrical Code or your local electrical code.

WARNING

Never work on pump while it is running or power is still connected; hazardous voltage can cause severe or fatal injury. A suitable ground fault interrupter should always be installed at the power supply source of this unit.
