BIOSHIELD®UV Disinfection Sterilizer Air Relief Kit Installation Guide
Introduction
The Bioshield®UV Disinfection Sterilizer Air Relief Kit contains everything you
need to install the air relief valve and pressure gauge on a residential Bioshield
system.
Removing the Quartz Sleeve
1. Disconnect all power to the UV
sterilizer and pool pump at the
circuit breaker.
2. Relieve any residual pressure that
may remain in the system.
3. Unthread the black Retaining Nut
and gently slide the Quartz Sleeve
Assembly and Lamp out of the UV
vessel (see Figure 1).
Note: Place the Retaining Nut
to the side; it will be used during
installation of the air relief kit.
Place the Quartz Sleeve Assembly
and Lamp inside the packing
tube that the lamp was originally
shipped in. This will protect the
quartz sleeve from damage and
fouling.
Installing the Air Relief Kit
All connections made while installing the
air relief kit should be hand tight. Loose
connections will result in leaks from the
retaining nut or the mating end of the air
relief valve.
1. Position the Seal Plate O-Ring and
Valve Seal Plate onto the UV vessel
(see Figure 3).
2. Thread the retaining nut down on
to the UV vessel and hand tighten
down on to the Valve Seal Plate
(see Figure 3).
3. Thread the Air Relief Valve into the
Valve Seal Plate until hand tight
(see Figure 4).

Installing the Air Relief Kit (cont.)
4. Remove the nut from the top of the Air
Relief Valve with a 1/4” adjustable or open-
end wrench.
5. Apply thread seal tape to the threads of the
pressure gauge, making sure not to cover
up the opening in the valve gauge’s stem.
6. Carefully thread the pressure gauge into
the top of the Air Relief Valve. Tighten the
pressure gauge until secure which should
take about 4 to 6 complete turns (see
Figure 5).
Note: Always position the gauge so that the face of the gauge can be
read easily.
To remove the Air Relief Kit, follow the instructions above in reverse
order. To reinstall the quartz sleeve and UV lamp, refer to “Quartz Sleeve
Assembly and Installation”, found in the Bioshield®UV Disinfection
Sterilizer Installation and User’s Guide.
Cleaning the Air Relief Valve
The Air Relief Valve may become clogged or dirty after prolonged use and
may require periodic cleaning. Below are instructions on disassembling and
cleaning the valve.
1. Open the Air Relief Valve until it snaps
into the full open position and wait for
all air to be released.
2. With the Air Relief Valve attached to
the UV sterilizer, pull out the Locking
Tabs on the sides of the valve and
remove the Valve Stem and Cover
Assembly with a counterclockwise turn
and lifting motion (see Figure 6).
3. Clean debris from the valve stem and
body.
4. Ensure that the air passage is open
by inserting a 5/16” drill bit through the
Valve Body.
5. Inspect the valve’s two O-rings and
ensure they are both free of damage,
properly positioned (see Figure 6),
and lubricated with a silicone-based
lubricant.
6. Reinstall the Valve Stem and Cover Assembly with a downward and
clockwise motion until it snaps into position.
