Frequently Asked Questions - TruChlor Erosion Feeder Jandy

How to install the TruChlor Erosion Feeder inline?

Install the device downstream of the filter and heater (if present). Use Jandy universal fittings glued to 2" or 2.5" PVC pipe. Ensure the arrows on the body indicate flow direction toward the pool. Do not directly connect a 90° elbow to the inlet; allow at least a 6" straight section.

How to install the offline model?

Position the device near the filter and pump on a flat surface. Connect the inlet downstream of the pump and filter, and the outlet downstream of the heater (or downstream of the filter if no heater). Use either the supplied black flexible hose (with compression nuts and cones) or 1/2" Sch 40 rigid PVC pipe (with socket nuts and O-rings).

What type of tablets can I use?

Use only slow-dissolving Trichlor tablets, 1" diameter for spas, or 1" or 3" for pools. Never mix different types of chlorine and do not use calcium hypochlorite or bromine.

How to adjust the chlorine level?

Turn the control knob counterclockwise to increase water flow through the device and thus the amount of chlorine. Start at 50%, then test residual chlorine (1-3 ppm) and adjust. Turn clockwise to reduce chlorine.

What to do if there is a leak around connections?

Check the condition of the O-rings. Replace them if damaged, cracked, or swollen. Ensure the nuts are hand-tight. Use only compatible silicone lubricant for O-rings.

How to winterize the device?

Remove all undissolved tablets and rinse the body with clean water. Open the drain plug at the bottom to fully drain the device. Follow other winterization procedures for your system.

Why is flow reduced or the flow indicator not moving?

This may be due to a blocked valve assembly or obstructed chlorinator body. Remove the replaceable valve assembly and clean any scale or debris. The bottom grid can also be removed for cleaning.

Is it compatible with a variable speed pump?

Yes, the TruChlor VS inline model comes with a variable speed insert kit (low-flow inlet, cone, and outlet) for systems with low-speed flow below 50 gpm (189 L/min). If low speed exceeds 50 gpm, remove the inserts.

How to safely replace tablets?

Stop the pump and close the control valve. Loosen the lid without removing it, wait one minute for gases to escape. Slowly remove the lid away from you. Fill with tablets, then replace the lid after lubricating the O-ring with silicone. Reopen the valve and restart the pump.

What are the risks if calcium hypochlorite is used?

Using calcium hypochlorite in this device can cause fire or explosion. Never use this substance. Strictly follow the warnings in the manual.

Section 3. In-line Installation

! CAUTION

DO NOT INSTALL chlorine feeder before the heating system. Damage to the heating system may occur.

WARNING

In order to prevent risk of serious property damage, injury or death: Wear eye and skin protection while maintaining or servicing this unit. Do not inhale fumes from the chlorinator or chemical container. Chlorine feeder may be under pressure. Use caution removing cover.

Figure 3. Feeder Dimensions

1. Install unit downstream of the filter and heater (if present).

IMPORTANT: Heaters and other equipment may be damaged by highly chlorinated water. A check valve should be installed before the erosion feeder to avoid damage to heater.

NOTE: For a pool/spa combo with 2" PVC plumbing and equipment, install the feeder on the pool return line after the diverter valve that diverts water to the spa. Then install a minimum section of 6" x 1.5" PVC pipe from the diverter valve into the inlet side of the feeder using 1.5" unions. Continue with 2" PVC pipe on the outlet side of the feeder. This will compensate for the water being diverted to the spa.

1. Glue Jandy Universal Unions into 2" or 2 1/2" PVC pipe.
2. When plumbing 90 degree elbows directly into the feeder inlet it may cause turbulence inside the elbow which prevents water from entering the feeder. A minimum of 6" PVC pipe should be installed between the elbow and the inlet of the feeder.
3. Ensure valve nuts are hand tight.
4. The arrows on feeder body should point in the direction of the water flow returning to thepool.
5. Use only PVC cement. Follow the directions on the cement label. Allow time for the PVC cement to completely dry.

Section 5. Operation

NOTE: The consumption of chlorine in swimming pools varies according to use, temperature, exposure to sunlight, and other factors. Initially you will need to experiment with the control valve to ensure that the unit doses enough chemical to maintain an adequate residual. Start with the valve in the 50% position. Test the residual regularly using instructions below.

WARNING

Elevated Chemical Concentrations and Hazardous Gas - The introduction of potentially hazardous gas or elevated chemical concentrations into the pool or spa during backwash and periods of no flow in the circulation system may cause serious personal injury, or death. To avoid, use the following guidelines:

• Set dosage indicator to zero before stopping water flow through the chlorinator.
• Minimize backwash time.
• Do not shut off pump for extended periods.

• Do not allow bathers into the pool or spa area until full flow through the circulation system has been established.

• This tablet feeder is designed to help you maintain a chlorine residual. Always start a new feeder installation by ensuring that the chlorine is already at a proper residual level. Consult your local dealer for water conditioning information in your area. The residuals should be 1-3 ppm of free chlorine.

• Remove cap of feeder and fill with proper size tablets. For pools use 1" or 3" diameter tablets. For spas use 1" tablets.
• Completely fill body with water, and bleed out entrapped air in all system lines. Replace cap making sure o-ring is clean, lubricated with silicone lubricant and in place.
• Turn on pump and timer switches for a minimum of 6 to 8 hours. The water level inside chlorinator will be 3 – 5 inches under normal running conditions.
• Adjust the control valve counter-clockwise for more flow through the erosion feeder and more chlorine. Or adjust clockwise for less chlorine according to the size of the pool/spa. Use a test kit to determine the chemical residual. Check the chemical residual daily for the first five days.

NOTE: Hot weather, high water temperature and increased use will cause the pool/spa to use more chemical. Increase the feed rate a few days in advance when possible. The valve settings may require adjustment depending on the conditions.

NOTE: If the feeder does not provide enough chemical residual when using 3" tablets, switch to 1" tablets for faster erosion and increased residual.

NOTE: When maintaining the chlorinator, always check o-rings for damage, breaks, swelling, etc. Replace if necessary. (see Replacement Parts list)

Replacing Tablets

WARNING

In order to prevent risk of serious property damage, injury or death:

• Wear eye and skin protection while maintaining or servicing this unit.
• Do not inhale fumes from the chlorinator or chemical container.

• Chlorine feeder may be under pressure. Use caution removing cover.

• Shut off the pump and turn the control valve to the closed position. The check valve will prevent water from entering the feeder.

• Loosen cap but do not remove. Wait one minute to allow water and fumes to drain from feeder.
• Leave the control valve closed. Slowly remove the cap by tilting it away from yourself, such that any remaining gas that escapes is directed away from you. Check the position of the internal grate after each refilling. The grate may come out of its resting place when tablets are added to the chlorinator.
• Fill the feeder with tablets. NEVER MIX CHLORINE TABLET TYPES. DO NOT USE WITH CALCIUM HYPOCHLORITE OR BROMINE.
• Completely fill body with water, and bleed out entrapped air in all system lines.
• Replace cap making sure o-ring is clean, lubricated with silicone lubricant, and in place. Lubricate o-ring with approved silicone o-ring lubricant only. (Hand tighten only).
• To maintain knob range of motion and o-ring seal, fully rotate control valve before setting output level. Turn knob clockwise to 0 (closed), then counter-clockwise to 100 (fully open) and then open control valve to desired setting.

NOTE: Keep an eye on the tablet level in the unit, preferably reload BEFORE they run out.

WARNING

To avoid risk of property damage, serious injury or death, Calcium Hypochlorite is not to be used in any form.

Section 6. Winterizing

NOTE: If the equipment room or pool pad is subject to freezing conditions, it will be necessary to drain your dosing unit following these instructions.

1. This chlorinator has a drain plug located on the bottom for easy draining of the unit for winter.
2. Remove any remnants of undissolved chemical tablets and rinse out the body with clean water.
3. Follow other normal procedures for your system to winterize.

Section 7. Troubleshooting

SYMPTOM CAUSE CORRECTIVE ACTION
Glass lid is cloudy	Chlorine exposure Remove the lid and wipe clean. If it remains cloudy, it will clear itself if left exposed to sunlight and fresh air. DO NOT leave chlorinator open without the lid installed. If the lid must be left off to clear up, a replacement must be installed temporarily
Reduced Flow / Low Chlorine / Flow Indicator Not Moving	Clogged valve assembly	Remove the replaceable valve assembly. It can be detached to clean any build-up or debris.
	Clogged chlorinator body	The bottom grate can be removed when chlorine is gummed up inside the unit. The chlorine residue must be dislodged or it may affect feeder performance. The grate helps keep pieces of the tablets from clogging the outlet.
Leaks around connections	Damaged o-rings Check o-rings for damage, replace as needed.
Low chlorine concentration in the pool	1. The trichlor tabs have been consumed2. Filtration time too low3. Chlorine demand too high	1. Add trichlor tablets in the unit.2. Increase filtration daily time.3. If using 3" tabs, use 1" instead.
Water is green and/or algae is present	A water parameter is not properly maintained (pH, cyanuric acid, etc)	Contact your pool professional for more details and actions

APPENDIX - SYSTEM PLUMBING

The diagrams below cover common plumbing configurations. For other configurations or installation questions, please call Technical Support.
