Mandatory Leak Test

A leak test should be performed each time the quartz sleeve is installed inside the unit’s vessel or when the quartz sleeve
or gaskets and o-rings are replaced [Once annually]. Performing a leak test is a precautionary measure that will determine
whether or not the critical seal between the quartz sleeve and quartz sleeve module has been achieved.
Failure to achieve a proper quartz sleeve/quartz sleeve module seal during Bioshield

UV Disinfection Sterilizer operation

will allow water to leak into the inside of the quartz sleeve, potentially damaging the UV lamp and other electrical
components, which could develop into dangerous situations.
IMPORTANT NOTE: Failure to perform a leak test could lead to conditions that will void your product warranty.

To Perform Mandatory Leak Test:
1. Prepare the UV system for permanent operation by plumbing it in-line, into a lter

system using the plumbing hardware of your choice. If PVC glue is used, follow the
glue manufacturer’s instructions. If needed, use a bypass assembly for greater water

ow control (see the Figure A).

2. If UV lamp is installed, with the unit plumbed for operation and the clear quartz sleeve

module securely in place, remove the UV lamp from the quartz sleeve module.

3. Roll-up a few paper towels creating a core approximately 3/4-inch diameter, 10-inches

long then slide into the open quartz sleeve module port. Insert about 6-inches of the
paper towel core down into the quartz sleeve, as shown in Figure B.

4. With the paper towel in place, turn on the pump and recirculate water through the UV

vessel for at least thirty (30) minutes.

5. After thirty (30) minutes of recirculating water through the UV vessel, remove the paper

towels from the quartz sleeve module. Inspect closely for moisture. If the paper towels
are completely dry, your leak test is complete and successful.

If moisture is detected on the paper towel the quartz sleeve’s rubber gasket and o-ring
have failed to achieve a seal and must be re-assembled; repeat the leak test until a
seal is achieved. See page 4 for assembly instructions.

Electrical Connection

The Bioshield UV system is intended to be permanently connected to a Listed Pool Controller (i.e. IntelliTouch

or EasyTouch

Control Systems) or a Listed Mechanical Timer Switch that provides a wiring compartment for the connection of ancillary
equipment.

To Connect the UV System to a Listed Pool Controller:
1. Route the UV power supply cable through the 1/2-inch trade size conduit opening in the bottom of the control system

enclosure.

2. Use the strain relief provided with the UV system to secure the power supply cable to the control system enclosure.
3. Connect the power supply cable leads to the appropriate terminations inside the control system.

Note: The cable leads are tinned, or provided with Listed Wiring Connectors (i.e. spade or closed loop), to allow for
quick connection to either a relay terminal, wiring bar or other conductor termination.

To Connect the UV System to a Listed Mechanical Timer Switch:
The UV system must be wired to the load side of the listed timer switch. This will ensure the UV system only operates
when the pump is running. Refer to the instructions and wiring diagram below to properly wire the power supply to a listed
timer switch.
1. Wire the power supply’s BLACK lead to the terminal

marked “L1”.

2. Wire the power supply’s WHITE lead to the terminal

marked “N” (Neutral) in 120 VAC installations or to
the terminal marked “L2” in 240 VAC installations.

3. Wire the GREEN lead to the terminal marked “GND”

(Ground).
