TYPICAL LAYOUTS

ODOUR CONTROL SYSTEMThe Expella Odour Control System couples directly to the rear of the toilet and gently draws air from the toilet pan via the flushing rim.

The system extract oudours before they disperse across the whole bathroom and in some cases adjoining rooms.

BEFORE YOU STARTThe Expella system is designed to attach the rear of your toilet cistern to draw air from the toilet bowl through the overflow pipe in your cistern to the outside atmosphere.As such a hole is required on the back of the toilet cistern. Some toilet suites are manufactured with a suitable hole which can accept the Expella system. Expella systems are also compatible with in-wall concealed cisterns.If your cistern does not have a hole or opening, please contact Expella Pty Ltd to arrange drilling of the cistern by an experience tradesman. If you are connecting to an existing toilet, remember to turn off the water supply, then empty the water from the cistern (by flushing several times) prior to removing cistern from the wall.

NOTE: Expella Systems are not compatible with Pozzie Genori toilet suites.

Expella O&S KitINSTALLATION INSTRUCTIONS

MAIN DUCT RUN & FAN INSTALLATION Refer to Figure 3 on following page

01/ Install main duct run from the location of the shower diffuser via the proposed toilet branch to the location of the fan unit. Continue main duct run past fan location to discharge point.

02/ Install fan unit above ceiling level with brackets as illustrated. Ensure the arrow on the fan unit is directed toward the point of discharge.

03/ Connect 100mm flex to main duct run, securing connection with duct tape.

04/ After the ceiling has been installed, cut 100mm hole into ceiling at location of shower and pull flex through 100mm hole. Connect diffuser collar to flex then fix collar to underside of ceiling.

NOTES:

• Provide sufficient access to fan via man-hole or access panel.

• Expella recommends the use of rigid ABS or polypropolene piping. PVC pipe (stormwater or drainage grade) is also suitable.

• If possible, minimise use of flexible duct.

• Wherever flexible duct is used, ensure the duct is stretched tight to minimise air turbulence and maximise air flow.

TOILET CONNECTION Refer to Figures 1, 2 and 3 (following page)

01/ Check toilet dimensions and mark out the centre of the Cistern’s rear hole for connection to Expella on the wall.

02/ Run the 40mm PVC pipe inside the stud wall where the centre line of the cistern’s rear hole has been marked. If you have a masonry wall, you will need to chase a vertical channel into the wall approximately 45mm deep.

03/ Connect 40mm joiner and 40mm diameter flex to bottom of vertical duct at approximate height of cistern hole. This flex allows a small amount of tolerance when fixing the cistern. Secure join by wrapping duct tape around PVC pipe, joiner and flex.

04/ Connect 90° (40mm internal diameter) PVC Bend to the top of the vertical duct using PVC glue.

05/ Run 40mm PVC pipe to main duct run and connect to 40mm x 100mm Boss Junction as illustrated.

06/ Fix discharge grille at point of discharge from main 100mm duct run using minimal amount of 100mm flexible duct. Refer to discharge option diagrams.

07/ Fix shower diffuser after ceiling has been painted by screwing diffuser into collar.

08/ Attach cistern. Feed 40mm flex pipe through rear opening on cistern and trim excess flex.

09/ Fix Expella non-return valve to 40mm flex inside the toilet cistern. Rotate the valve to ensure the Cistern lid sits flush on toilet cistern. (Refer to Figure 1)

NOTE:

Once installed, seal any gaps with a suitable filler as the gaps may affect performance of the system.
