WARNING: RISK OF ELECTRIC SHOCK
Install at least 5 feet (1.5 m) from tub water using nonmetallic plumbing. Install blower no less than 1 foot (305 mm) above the maximum water level or with an approved Hartford loop configuration as outlined in section 2 "Plumbing" to prevent water from contacting electrical equipment. Install in accordance with the installation instructions.
Pressure Testing:
- To minimize the risk of severe injury or death, the appliance should not be subjected to the piping system pressurization test. Local codes may require the pool piping system to be subjected to a pressure test. These requirements are generally not intended to apply to pool equipment. Zodiac® pool equipment is pressure tested at the factory.
- However, if the WARNING cannot be followed and pressure testing of the piping system must include the appliance, BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS:
- Check all clamps, bolts, lids, lock rings, and system accessories to ensure they are properly installed and secured before testing.
- Release all air in the system before testing.
- Test water pressure must NOT EXCEED 35 PSI.
- Water temperature for test must NOT EXCEED 100°F (38°C).
- Limit test to 24 hours. After test, visually check system to be sure it is ready for operation.
NOTICE: These parameters apply to Zodiac equipment only. For non-Zodiac equipment, consult the equipment manufacturer.
To Reduce the Risk of Injury:
- a) The water in a spa should never exceed 104°F (40°C). Water temperatures between 100°F (38°C) and 104°F (40°C) are considered safe for a healthy adult. Lower water temperatures are recommended for young children and when spa use exceeds 10 minutes.
- b) Since excessive water temperatures have a high potential for causing fetal damage during the early months of pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 100°F (38°C).
- c) Before entering a spa or hot tub, the user should measure the water temperature with an accurate thermometer since the tolerance of water temperature-regulating devices varies.
- d) The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with the possibility of drowning and can greatly increase the risk of fatal hyperthermia.
- e) Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory system problems, or diabetes should consult a physician before using a spa.
- f) Persons using medication should consult a physician before using a spa or hot tub since some medication may induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.
- g) People with infectious diseases should not use a spa or hot tub.
- h) Exercise care when entering or exiting the spa or hot tub.
- i) Water temperature in excess of 100°F (38°C) may be injurious to your health.
- j) Do not use a spa or hot tub immediately following strenuous exercise.
- k) Prolonged immersion in a spa or hot tub may be injurious to your health.
- l) Do not permit any electrical appliance (such as a light, telephone, radio, or television) within five 5 feet (1.5m) of a spa or hot tub.
To reduce the risk of injury, do not permit children to use this product.

SAVE THESE INSTRUCTIONS
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
Calculate Back Pressure
Calculate back pressure as a measure of "inches of water". Verification of this figure can be made by using a manometer.
Formula Components:
- a: Vertical Measure from Pool/Spa surface to air outlet
- a¹: Vertical Measure from air outlet to lowest check valve (See Note). Include a¹ for installations with a check valve below the air outlet only. For above grade installations, enter 0 for a¹).
- b: Number of feet of 2" Pipe
- c: Number of 90° Elbows
- d: Number of 45° Elbows
- e: Number of 1/2 lb check valves
Diagram Description: A diagram illustrates how to measure 'a' and 'a¹', and shows pipe ('b'), elbows ('c', 'd'), and check valves ('e') in a typical plumbing setup.
Total Back Pressure (Inches of Water) = [Calculation based on inputs]
Calculate Airflow
Choose an air hole size from the chart at left and apply the conversion factor in the formula below to determine total airflow in standard cubic feet per minute (SCFM).
| AIR HOLE SIZE | CONVERSION FACTOR |
|---|---|
| 1" | 2.4 |
| 1 1/8" | 1.5 |
| 1 1/4" | 1.1 |
| 1 3/8" | 0.6 |
| 1 1/2" | 0.27 |
| 1 5/8" | 0.15 |
| 1 3/4" | 0.1 |
Total Airflow (SCFM) = [No. of Holes] x [Conversion Factor]
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 electrocution causing severe injury or death.
Determine Blower Needed
Locate the total back pressure, calculated above, and draw a horizontal line. Locate the total airflow from the previous step and draw a vertical line. These lines will intersect on the performance curve of the minimum HP blower required for your application.
Diagram Description: Performance Curves (60 HZ) are shown, plotting Air Flow Rate (SCFM) against Pressure H2O (Inches of Water). Lines indicate maximum back pressures (40", 50", 65") and required HP based on the intersection of calculated back pressure and airflow. Models are associated with specific maximum back pressures.
| Voltage | 1.0 HP | 1.5 HP | 2.0 HP |
|---|---|---|---|
| 120V | PSB110 | PSB115 | PSB120 |
| 240V | PSB210 | PSB215 | PSB220 |
4. Install Blower
Installation must be done in accordance with the National Electrical Code® ("NEC®" or NFPA-70®) in the US, the Canadian Electrical Code ("CEC" or CSA C22.1) in Canada, and/or any other local and national installation codes.
- Refer to the "Select Blower" section (facing page) to ensure that you have the correct blower size for your application.
- Pressure tests to the system should be done prior to the installation of the blower. See Warning Section on adjacent page.
- Use 2" PVC pipe from the blower to jets or bubblers.
- Slide Blower onto PVC Pipe. Lower until the stop tabs make contact with the PVC pipe.
- Blower should be installed vertically, away from direct sunlight.
- Do not glue or otherwise permanently attach the blower to plumbing.
- Do not remove the blower check valve diaphragm.
- Drill two (2) 1/8" pilot holes through the textured fastener safe area marked on the blower body. The holes should be drilled through the blower body and PVC pipe. The holes should be oriented 180° from one another.
- Install one (1) 1/2" 8-18 thread forming screw into each of the previously drilled pilot holes. The screws and pipe should not interfere with the normal travel of the check valve diaphragm.
- The blower also comes equipped with a mounting bracket which can be used to secure the blower to a vertical surface such as a wall or post.
- If not used, the bracket can be removed and stored.
CAUTION: Blower must be affixed to the plumbing using the fasteners recommended in these instructions. Failure to do so may allow the blower to come free of the plumbing during operation which could damage equipment and prevent proper blower operation.
WARNING: Blower must be installed in an area well away from sources of exhaust such as gas pool and spa heater. Please ensure that this blower is installed according to local codes and Authority Having Jurisdiction (AHJ) requirements.
WARNING: Do not use chemical adhesives to affix the blower to the air inlet line. Fumes from chemical adhesives may accumulate in the piping and explode causing property damage, serious injury or death.
Diagram Description: Diagrams illustrate the blower attachment to 2" PVC pipe using screws through designated "Fastener Safe Area" on the blower body. An illustration shows the "Diaphragm Travel Distance" and "Stop Tabs". A mounting bracket is also depicted.
2. Plumbing
Diagrams illustrate various plumbing configurations:
- STANDARD INSTALLATION: For Venturi Jets or Sump Bubbler Jets, with air line typically less than 25 feet. Requires 12" minimum clearance to water level.
- LONG RUN INSTALLATION: For air lines over 25 feet from the spa wall.
- BELOW GRADE INSTALLATION: For installations where the blower or air line may be below the water level.
Hartford Loop: Use this configuration if the blower air line drops below the spa water level to prevent the line from filling with water. It involves routing the air line upwards and then downwards before connecting to the jets, ensuring the highest point of the loop is above the water level.
Check Valve: Install a 1/2 lb. U.L. listed check valve between the blower and the jets to prevent water damage to the blower. Ensure that check valves are accessible for servicing.
Note: Do not install adjustable jets, as they may cause excessive back pressure.
Diagram Description: Detailed diagrams show the plumbing for Standard, Long Run, and Below Grade installations, including placement of the blower, 2" PVC pipe, check valve, jets, and water lines. The Hartford Loop configuration is also illustrated.
