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.

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 the 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 equipment manufacturer.
Installation must be done in accordance with the National Electrical Code® (“NEC®” or NFPA-70®) in the US, the Canadian Electrical Code (“CEC” or C22.1) in Canada, and/or any other local and national installation codes.
RISK OF ELECTRIC SHOCK, FIRE, PERSONAL INJURY, OR DEATH. When required by applicable local codes and/or by the Authority having jurisdiction (AHJ); Connect only to a branch circuit that is protected by a ground-fault circuit interrupter (GFCI).
Contact a qualified electrician if you cannot verify that the circuit is protected by a GFCI. Make sure such a GFCI is provided by the installer and should be tested on a routine basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power should be restored. If the GFCI fails to operate in this manner, the GFCI is defective.
If the GFCI interrupts power to the blower without the test button being pushed, a ground current is flowing, indicating the possibility of electrical shock. Do not use the device. Disconnect the device and have the problem corrected by a qualified service representative before using.

To reduce the risk of injury, do not permit children to use this product.
Jandy Blowers are powered by high-voltage electric motors and must be installed by a licensed or – certifi ed electrician or a qualifi ed swimming pool service technician.
Incorrectly installed equipment may fail, causing severe injury or property damage.
Do not install on a plumbing line that can be closed or shut off. The blower may create severe enough pressures to cause property damage or injury.

To Reduce the Risk of Injury –

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.
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).
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.
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.
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.
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.
People with infectious diseases should not use a spa or hot tub.
Exercise care when entering or exiting the spa or hot tub.
Water temperature in excess of 100°F (38°C) may be injurious to your health.
Do not use a spa or hot tub immediately following strenuous exercise.
Prolonged immersion in a spa or hot tub may be injurious to your health.
Do not permit any electric appliance (such as a light, telephone, radio, or television) within fi ve 5 feet (1.5m) of a spa or hot tub.

SAVE THESE INSTRUCTIONS

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 figure can be made by using a manometer.

Total Back Pressure (Inches of Water)

NOTE: Include a1 for installations with a check valve below the air outlet only. See “Below Grade Installation” on facing page for details. For above grade installations enter 0 for a1.

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.

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.

(Standard Cubic Feet Per Minute)

Determine Blower Needed

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

PLUMBING

STANDARD INSTALLATION

LONG RUN INSTALLATION (over 25’ from spa wall)

BELOW GRADE INSTALLATION

Hartford Loop – To install the blower below water level, or if the blower air line drops below the bottom of the spa, use the Hartford Loop plumbing configuration to prevent the air line from filling with water.

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

WIRING
