IntelliFlo 4 Installation and User’s Guide
Priming the pump for the first time or after service
Before the IntelliFlo 4 pump is started for the first time it must be primed. To prime a pump means filling the
pump and suction pipe with water. This process evacuates the air from all the suction lines and the pump. It
may take several minutes to prime depending on the depth of water, pipe size and length. It is easier to
prime a pump if you allow all the air to escape from the pump and pipes. The water cannot enter unless the
air can escape. Pumps do not hold prime, the pool piping system has that task.
CAUTION - To avoid permanent damage to the IntelliFlo 4 pump, before starting the pump, fill the IntelliFlo
housing strainer with water so that the pump will prime correctly. If there is no water in the stainer the pump will
not prime.
• NEVER run the pump dry! Running the pump dry may damage the seals, causing leakage and
flooding!
• Do not add chemicals to the system directly in front of pump suction. Adding undiluted chemicals
may damage the pump and will void the warranty.
• Open gate valves before starting system.
• Pump will prime itself when used in flooded suction system.
• Be sure to release all air from filter and piping system.
• The IntelliFlo 4 pump is a variable speed pump. Typically the lower speeds are used for filtration and
heating. The higher speeds can be used for spa jets, water features, and priming.
CAUTION - Before starting this procedure, first read the following
Before removing the pump lid:
1. Press the Stop button if the pump is running before proceeding.
1. Disconnect the communication cable from the pump.
2. Close the gate valves in suction and discharge pipes.
3. Release all pressure from pump and piping system.
4. Never tighten or loosen the clamp while the pump is operating.
WARNING! If the pump is being pressure tested, release all pressure before removing the trap cover.
Do not block the pump suction while the pump is running. If a body part blocks the pump suction it may cause
severe or fatal injury. Small children using the pool must ALWAYS have close adult supervision.
WARNING! FIRE and BURN HAZARD - The pump motor may run at a high temperatures. To reduce the
risk of fire, do not allow leaves, debris, or foreign matter to collect around the pump motor. To avoid burns when
handling the motor, shut off the motor and allow it to cool for 20 minutes before trying to work on it. The IntelliFlo
4 provides an automatic internal cutoff switch to protect the motor from heat damage during operation.
