Frequently Asked Questions - PSB120 Jandy

How do I prime the Jandy PSB120 pump?

Ensure the pump is filled with water before starting. Remove the lid, fill the strainer basket with water, replace the lid securely, and then turn on the pump.

What should I do if the pump loses prime?

Check for air leaks in the suction side, and ensure the water level in the pool is sufficient. Also, inspect the lid O-ring for damage and lubricate if necessary.

How often should I clean the strainer basket?

Clean the strainer basket at least once a week, or more frequently if the pool has heavy debris. A clogged basket reduces flow and can damage the pump.

Can the PSB120 pump run dry?

No, running the pump dry can cause severe damage to the mechanical seal. Always ensure the pump is primed before operation.

What is the recommended voltage for this pump?

The Jandy PSB120 operates at 220-240V, 50 Hz. Ensure your electrical supply matches these specifications.

How do I winterize the pump?

Drain all water from the pump, remove the drain plugs, and store the pump in a dry, protected area. Use a winterizing kit if available.

Why is my pump making a loud noise?

Loud noises may be due to cavitation (low water level), a clogged impeller, or worn bearings. Check and clean the impeller, and ensure proper water flow.

What is the maximum flow rate of the PSB120?

The maximum flow rate is approximately 120 gallons per minute (GPM) at optimal conditions.

How do I replace the mechanical seal?

Turn off power, disconnect plumbing, remove the motor and volute, then replace the seal. Follow the detailed instructions in the manual. If unsure, contact a professional.

Is the PSB120 compatible with saltwater pools?

Yes, the pump is suitable for saltwater pools, but ensure regular maintenance to prevent corrosion. Rinse the pump with fresh water periodically.

USER MANUAL PSB120 Jandy

1. SELECT BLOWER

Correctly sizing the blower for your application is a critical step to the sustained operational quality of your Jandy Pro Series Pool and Spa Blower. Damage or failure due to an improperly sized blower is not covered under warranty.

SIZING WORKSHEETS: The worksheets below will guide you through the proper sizing calculations for your application.

Calculate Back Pressure

Calculate back pressure as a measure of "inches of water". Verification of this 1 gure can be made by using a manometer.

Total Back Pressure (inches of water)

NOTE: In order 2 for in particular with a cloud value below the air outlet type. See "the Grade isolated at" no heavy people for details. For above grade not so far any other

Calculate Airflow

Choose an air hole size from the chart at left and apply the conversion factor in the formula below to determine total air flow in standard cubic feet per minute.

No. of Holes Conversion Factor Total Airflow SCFM

WARNING

Installing an insufficiently sized blower will increase back pressure. Failure to accurately follow the blower sizing calculations provided could result in excessive back pressure. Excessive pressure can cause damage that could result in electricisation causing severe injury or death.

Determine Blower Needed

Locate the total back pressure, calculated above and draw a horizontal line. Locate the total air flow from previous step and draw a vertical line. These lines will intersect on the performance curve of the minimum HP browser required for your application.

BELOW GRADE INSTALLATION

Installation of this equipment should be performed by a licensed electrician and conform to all National Electrical Code® (NEC®), state and local codes.

1. Ensure all power to the blower has been disconnected at the main breaker.

2. Remove blower front door by removing the two (2) screws along the door downward and pulling the door free.

3. Pull in voltage source and ground wire from Power Center.

4. Connect wires from power corner to the corresponding wires from the bower motor. Use the wiring diagrams below for reference. The 120 or 240 toggle switch will come preinstalled with flag terminals. Connections will need to be made with Wire nuts.
