Section 2. General Installation Requirements

This document provides instructions for installing the Jandy Laminar Jet with LED Lights. Read through the instructions completely before starting the procedure. The laminar jet is designed to provide a clear, adjustable stream of water that arcs high up and out into the pool.

The laminar jet comes with a built-in LED light module or a fiber optic module that accepts lighted fiber optics. These light sources light the arc of water creating a dazzling nighttime effect. This unique water feature is easily installed and multiple jets can be combined to create spectacular water entertainment.

To properly install this product please review the following installation and maintenance instructions.

2.1 Water Source

The laminar jet water supply line must be filtered by a cartridge filter (do not use a sand filter). If you are using a dedicated filter - it must be a minimum of 20 sq-ft (1.85m^2) . For multiple jet installations, use a minimum of 100 sq-ft (9.3m^2) , such as the Jandy CS100 filter.

2.2 Pump

The required minimum pump flow for each laminar jet is shown in the table below:

Laminar Jet Water Volume and Pressure Chart
Gallons (US gpm/lpm) 7.5	/28 8/30	8.5/32
Inlet Pressure (psi) 9.5	10.3 11
Height of Jet (ft/m) 5/1.5	6/1.8 7/2.1

2.3 Plumbing

Each laminar jet requires a 1½ to 2 in (38 - 50 mm) PVC main feed line with 1 in (25 mm) PVC entering the deck canister. A check valve is also required and should be placed as far from the deck canister as possible to minimize water turbulence.

2.4 LED Light Module

The 12V LED light module offers vibrant lighting in nine (9) brilliant colors and five (5) festive color shows that can be controlled manually, by the AquaLink® RS Control System (Rev O or newer) or by the Jandy PDA Control System (Rev 4.0 or newer). The light module can be synchronized with Jandy's Pool and Spa LED lights and operates on less than 25 watts of power.

2.5 Conduit/Fiber Optics Module

If installing fiber optics, each laminar jet will require 100 to 150 strand fiber optic cable. One hundred-fifty strand cable is recommended due to the enhanced lighting effects.

2.6 Critical Placement Dimensions

The laminar jet can project a maximum of 7 feet (2.1 m) up and 8 feet (2.4 m) out into the water. Therefore, ensure the installation is no more than 6 feet (1.8 m) from the inside edge of the pool.

NOTE: To avoid water spray on the deck in high wind areas, place the laminar jet closer to the edge of the pool.

NOTE: The deck canister lid can only rotate approximately 90 degrees to the left or the right. Therefore, make sure that the deck canister is positioned towards the desired target location (see Installing the Deck Canister) prior to completing the installation.

Risk of Electrical Shock or Electrocution which may result in serious injury or death. The Jandy Laminar Jet are only available for 12-volt AC power. For supply connection, use only an isolating low voltage power supply with ungrounded output, listed by an NRTL for swimming pool use. A Ground Fault Circuit Interrupter (GFCI) for 120 Volt transformers should be used if required by the transformer manufacturer or if required by the local applicable code and/or Authority Having Jurisdiction (AHJ). When a GFCI is used, the conductors on the load side of the GFCI circuit shall not occupy conduit, boxes, or enclosures containing other conductors unless the additional conductors are also protected by a GFCI. Refer to local codes for complete details. This laminar jet with LED light must be installed by a licensed or certified electrician or a qualified pool serviceman in accordance with the National Electrical Code® and all applicable local codes and ordinances. Improper installation will create an electrical hazard, which could result in death or serious injury to pool or spa users, installers or others due to electrical shock, and may also cause damage to property.

WARNING

Always disconnect the power to the laminar jet with LED light at the circuit breaker before installing or servicing the light. Failure to do so could result in death or serious injury to serviceman, pool or spa users or others due to electrical shock.

4.1 Preparing the Laminar Jet with LED Light for Installation

NOTE: The electrician must complete preparatory steps before the laminar jet with LED light is installed.

Ensure that the pool meets the requirements of the current National Electrical Code and all local codes and ordinances. A licensed or certified electrician must install the electrical system to meet or exceed those requirements before the laminar jet with LED light is installed. Some of the requirements of the National Electrical Code, which the pool electrical systems must meet, are as follows:

1. The low voltage transformer must be located at least 8 inches (20 cm) above water level, at least 4 inches (10 cm) above ground level, and at least 4 feet (1.2 m) from the edge of the pool.

2. All metal items within 5 feet (1.5 m) of the pool must be properly electrically bonded to a reliable point of grounding.

4.2 Installing the Laminar Jet with LED Light

NOTE: Perform these steps only after the electrical system requirements are met.

1. Feed cord through conduit to low voltage transformer, leaving at least 4 feet of cord at the light fixture to coil into the deck canister. The 4 feet (1.2 m) of cord allows the light to be easily serviced.

2. Cut the cord at the low voltage transformer, leaving at least 6 inches (15 cm) of cord to make connections.

3. Strip 6 inches (15 cm) of the outer cord jacket to expose the three (3) insulated wires. Be careful not to damage the insulation on the three (3) inner wires.

4. Install strain relief over cord jacket and connect all three (3) wires to the corresponding circuit wires in the low voltage transformer. Install the low voltage transformer cover.

4.3 Wiring Options for Controlling Laminar Jet with LED Lights

NOTE: The laminar jet with LED lights will not operate properly with light dimmers. Do not wire the laminar jet with LED lights to any dimming circuitry.

To the extent allowed by code and capacity of the electrical equipment, multiple laminar jets with LED lights may be controlled with a single switch so their colors will always be synchronized.

Separate switches may be used to control the on/off and color functions of each laminar jet with LED light. It is recommended that these switches be located next to each other to facilitate simple color synchronization when desired. All switches must be operated at the same time to assure color synchronization. Otherwise, the lights will work independently of each other.

4.3.1 Wiring to an AquaLink® RS Control System

The laminar jet with LED light can be wired into the Jandy AquaLink RS control system to provide simplified operation of the lights, as well as a means to synchronize the color change function. Connect the laminar jet with LED lights to one of the auxiliary relays in the Power Center.

NOTE: It is recommended to connect one (1) laminar jet with LED light per relay so each light can be controlled separately. However, up to four (4) laminar jets with LED lights can be connected on a single relay. If there are more than four (4) lights installed on one (1) AquaLink RS system, ensure there is more than one (1) auxiliary relay available in the Power Center.

Connect the laminar jet with LED lights to the power center.

NOTE: The laminar jet with LED light operates only on 12 volts AC. A suitable 120-volt/12-volt stepdown AC transformer MUST be used. Read further for more important details.

4.3.2 Wiring to a Time Clock

The laminar jet with LED lights can be wired into a basic time clock to automatically turn on the laminar jet with LED lights at a predesignated time. Connect the laminar jet with LED lights into the time clock.

4.3.3 Wiring to a Switch

The laminar jet with LED lights can be wired into a switch to manually turn on/off the lights. Connect the laminar jet with LED lights into the switch.

4.4 Twelve (12) Volt Transformer Installation

The laminar jet with LED lights requires the use of a 120/12VAC-100 watt low voltage lighting transformer.

NOTE: For optimum performance Zodiac Pool Systems, Inc. recommends using one transformer per 12-volt laminar jet. However, it is possible to power up to 4 laminar jets with one 200 watt transformer.

To ensure maximum safety, the transformer used to power the laminar jet with LED lights must be one that is listed by a Nationally Recognized Testing Laboratory (NRTL) for the application.

NOTE: If the pool already has a low voltage transformer powering the pool and/or spa lights, do not use the same transformer to power the laminar jet with LED lights. This is to ensure that the laminar jet's LED lights are only turned on when the laminar jet pump is running.

Section 5. Laminar Jet with Fiber Optic Module Installation (Use with JLFBR Series)

5.1 Items Required

The tools and supplies necessary for installation of the fiber optic module:

Tools	Utility knife or hot knife; Heat gun or propane torch.
Cable	Each jet requires 100 to 150 strands of fiber optic cable. Do not use more than 40 feet (12 m) of cable per nozzle as light output will be diminished.
Illuminator	Use illuminator with sufficient capacity of lighting effect intended.
Additional Materials	Electrical tape; Silicon (RTV)

5.2 Installation

1. Remove 6 inches (15 cm) of the cable jacket.
2. Using black electrical tape, tightly tape over the exposed fiber leaving approximately 12 inch (13 mm) exposed fiber at the end of the cable. The tape prevents the individual fibers from separating.
3. With a hot knife, cut the fiber optic cable so that the cable end is a flat surface. For best results, heat knife to cherry red.

NOTE: Do not cut the fiber ends too close to the taped edge. Leave a 14 inch (6 mm) distance between the cable end and the end of the taped edge. This will prevent adhesive on the tape from melting and getting on the ends of the fiber optic strands.

1. Slide the completed fiber optic cable through the Heyco ^® * waterproof fitting and up the tube (located at the bottom of the jet) until the cable bottoms out on the lens inside unit. Secure the fiber by tightening the waterproof fitting.

*Heyco is a registered trademark of Heyco Products, Inc.

NOTE: Allow at least four (4) feet (1.2 m) of extra fiber optic cable in the deck canister to allow the laminar jet to be easily removed.

1. Fill the electrical conduit between the opening and the fiber optic cable with RTV silicon to prevent water from entering the conduit. Let dry. The unit is now ready for operation.
2. Install illuminator and attach fiber optic cable according to instructions supplied with the illuminator.

Section 6. Starting the System

6.1 Install Jet Assembly

1. Disconnect the pressure cap that is installed on the flexible PVC hose.
   NOTE: The system should be pressure tested before starting the system.
2. Flush water lines to clear debris. Lines must be clear of debris before attaching the laminar jet assembly.
   NOTE: The finger screen is installed in the fitting under the cap. Remove the finger screen when flushing the line and reinstall the screen before installing the laminar jet assembly.
3. Connect the nut on the flexible hose of the laminar jet assembly and the threaded union of the flexible hose attached to the deck jet canister.

6.2 Set up Jet

1. Place the jet assembly into the canister and align the mounting brackets to the collar.
2. Ensure the flow adjustment valve is open by turning it counter-clockwise until it stops with a screw driver or a 1/2" (12.7 mm) socket wrench.
3. Turn on the water at a reduced rate and slowly fill the unit. When the unit is filled, increase the water supply until the jet stream reaches its intended target.

Screwdriver Lid Slot Light Intensity Adjustment Screw Angle Adjustment Slot Flow Adjustment Valve Laminar Jet 1" Stake Up Feature

Figure 10. Laminar Jet Light and Flow Adjustment

1. Use the flow adjustment valve to make final adjustments to the overall water height of the jets.

NOTE: Laminar jets are sensitive to wind, earth movement and equipment vibration. Secure the laminar jet and deck canister to minimize vibration. Periodic stream distortion caused by pump vibrations and motor electrical fluctuations is normal and not indicative of a nozzle defect. Also, occasionally a nozzle will "burp" due to pumped air collecting in the nozzle body. This is normal and will occur until all air is purged from the piping system. Trapped air can also cause slight distortion in water action. It is imperative that all air is removed to ensure proper water feature operation.

1. To adjust the angle of the jet move the laminar jet up or down to increase or decrease the angle by hand or using a screwdriver in the angle adjustment slot.

NOTE: The angle can be adjusted approximately 10^ .

1. The laminar jet is installed on two (2) pivots. Loosen the locking screws to adjust the jet angle. Once you are satisfied with the angle and location of the jet, tighten the locking screws.

2. Secure the deck canister lid to the deck canister collar, using two (2) #10 by 1½ inch (38 mm), Phillips flat head stainless steel screws.

Pivot Locking Screw

Figure 11. Locking Screw Location

NOTE: It is recommended to drill 1/8" (3 mm) pilot holes in the lid. Then the screws can be threaded into the holes. This will complete the installation and secure the jet from movement.

NOTE: When the light is turned OFF for more than seven (7) seconds, it will remain in the color set that is currently active. When the light is turned back ON, the light will be on the same color set.

7.2 To Reset to the Beginning of the Color Sequence

Turn the light OFF, wait four (4) to six (6) seconds, then turn ON, the light will return to the beginning of the color cycle (Alpine White).

NOTE: If an AquaLink® RS control system is being used the color set can be selected using the controller.

NOTE: To synchronize colors on multiple Jandy WaterColors light systems and Jandy Laminar Jets with LED Lights wired to separate switches, preform the above actions on all of the switches simultaneously. All Jandy WaterColors lights and Jandy Laminar Jet with LED lights will synchronize automatically if activated by the same switch. No other accessories are required.

Section 8. Light Intensity Set Up

8.1 Light Intensity Adjustment Set

NOTE: The LED light intensity can be adjusted to your preference. Increased water stream flow will cause a greater disturbance of the laminar jet stream and create a more intense light.

1. Use the light intensity adjustment screw attached to the scratcher to adjust the light intensity.

2. To increase the light intensity, turn the screw counter-clockwise to increase the water stream coming out of the scratcher. This water stream disturbs the surface of the laminar jet flow causing an increase in the light intensity.

NOTE: Laminar jets are sensitive to wind, earth movement and equipment vibration. Secure the laminar jet and deck canister to minimize vibration. Periodic stream distortion caused by pump vibrations and motor electrical fluctuations is normal and not indicative of a nozzle defect. Also, occasionally a nozzle will "burp" due to pumped air collecting in the nozzle body. This is normal and will occur until all air is purged from the piping system. Trapped air can also cause slight distortion in water action. It is imperative that all air is removed to ensure proper water feature operation.

Section 9. General Maintenance and Troubleshooting

CAUTION

The light engine assembly in the Jandy Laminar jet is sealed and therefore contains no serviceable parts. In order to prevent risk of property damage and/or injury, no service should be attempted to the light engine assembly in the event of a malfunction. The complete light engine assembly must be replaced.

Perform routine maintenance on the filter to ensure trouble-free nozzle operation. Be careful not to allow debris to enter the inlet plumbing when cleaning filters.

NOTE: Always flush lines after cleaning and backwash of filters.

9.1 Clogged Finger Screen

1. If the finger screen becomes clogged with debris causing the stream to be distorted, remove the laminar jet assembly by unscrewing the two (2) deck canister lid retaining screws.
2. Remove the deck canister lid and the jet assembly and place on the deck. Disconnect the union located on the flexible hose attached to the bottom of the jet assembly.
3. Remove the finger screen from the union and clean with a garden hose.

NOTE: Avoid damage to the nozzle opening. After clean up, reinstall the unions.

9.2 Winterization

The laminar jet can be winterized in regions that require winterization.

1. Remove the deck canister lid assembly and unscrew the 12 inch (13 mm) union.
2. Thread the cap on the flexible hose attached to the deck canister. The laminar jet can then be replaced in the deck canister or may be removed to a storage location. If left in the deck canister, tape over the slot opening to ensure no water will enter the system. If fiber optic cable is used, be sure to remove the retaining nut on the waterproof fitting on the bottom of the jet assembly.
