IMPORTANT: Place filter manual air relief valve  

  in the open position and wait for all pressure in  

  the system to be relieved.

 

  Before starting the system, fully open the manual  

  air relief valve and place all system valves in the  

  ‘open’ position to allow water to flow freely from the  

  tank and back to the tank. Stand clear of all  

  equipment and start the pump. 

  IMPORTANT: Do not close filter manual air relief  

  valve  until  all  pressure  has  been  discharged  

  from  the  valve  and  a  steady  stream  of  water  

  appears.

  Observe  filter  pressure  gauge  and  be  

  sure it is not higher than the pre-service condition. 

CHAPTER 2

INSTALLATION LOCATION

General Installation Information

 

• All work must be performed by a qualified service  

   professional, and must conform to all national,  

    state, and local codes. 

  • Install  to  provide  drainage  of  compartment  for  

    electrical components. 

 

• These instructions contain information for a variety  

   of pump models and therefore some instructions  

    may not apply to a specific model. All models are  

    intended for use with swimming pool applications.  

 

  The pump will function correctly only if it is properly  

    sized  to  the  specific  application  and  properly  

   installed.

WARNING:

  Pumps improperly sized or installed or  

  used in applications other than for which the pump  

  was intended can result in severe personal injury  

  or death. These risks may include but not be limited  

  to electric shock, fire, flooding, suction entrapment  

  or severe injury or property damage caused 

 

  by a structural failure of the pump or other system  

 component. 

WARNING:

  The pump can produce high levels of  

  suction within the suction side of the plumbing  

  system. These high levels of suction can pose a  

  risk if a person comes within the close proximity of  

  the suction openings. A person can be seriously  

  injured by this high level of vacuum or may become  

  trapped and drown. It is absolutely critical that the  

  suction plumbing be installed in accordance with the  

  latest national and local codes for swimming pools. 
  Locate pump as close to pool/spa as possible,  

  preferably in a dry, well ventilated area away from  

  direct sunlight. It should be on a hard, level surface.  

  Give consideration to:

    1.  Drainage – away from pump.

    2.  Ventilation of pump motor.

    3.  Access for future servicing and winterizing.

    4.  Protection from the elements.

CHAPTER 3

GENERAL PLUMBING

For Solvent Weld Connection

  Rigid or flexible PVC pipe can be used. Pipe ends  

  should be clean and free of any flash caused by the  

  cutting operation. Be sure that the proper adhesive  

  is used on the type of pipe specified. 

Note

: A primer  

  will assure that adhesive joints are superior. 

 

  Suregard P-3000 has a purple tracer to qualify in  

  areas where codes specify a primer must be used. 

 

Caution: 

We recommend that you consider 

 

  climatic conditions when applying adhesives. 

 

  Certain atmospheric situations, such as high 

 

  moisture content, make adhesive action of certain  

  glues less effective. Check the manufacturer’s  

 instructions.

For Threaded Connections

  Use  only  Teflon  tape  or  equivalent  on  threaded  

  plumbing connections. Other pipe compounds may  

  damage threads. We do not recommend the use  

  of silicone or petroleum based compounds. DO  

  NOT OVERTIGHTEN – HAND TIGHTEN PLUS ½ 

  TURN IS SUFFICIENT.

CHAPTER 4

PUMP PLUMBING

  Suction pipe should be as large or larger than 

  discharge pipe. Avoid using suction pipe smaller  

  than pump connection.  Keep the piping as straight  

  and short as possible, and of suitable size. Avoid  

  connecting an elbow directly into the pump inlet  

  (use a length of straight pipe to allow a proper  

  entry  for  the  water).  Arrange  horizontal  runs  to  

 

slope upward to the pump to prevent high spots that  

  could form air pockets. Support the pipe 

 

  independently so that it places no strain on the  

  pump. Keep as much of the suction line as possible  

  below the water level to reduce priming time. Install  

  valves and unions in the pump suction and return  

 

lines to facilitate servicing. Valves are recommended  

  for throttling maintenance if the system is installed  

  below deck level. Suction valves are essential for  

  priming all pumps without strainer bodies installed  

  above water level. Pumps with strainer bodies are  

  self-priming, nevertheless, we recommend the use  

  of check valve in the suction pipe at or below the  

  water level if the suction lift is more that five feet or  

  if the dry suction is more that ten feet long. Keep  

  the valve in the suction line fully open during  

 operation.
