11.3 BALLAST CONNECTION
The Output L and N of the controller PCB connect to the power input of the ballast according to the pin defini-
tion Live, Neutral and Ground. The other side ballast output has four pins for UV-C lamp connection.

VENTURI INSTALLATION GUIDE
Follow the instructions procedure below for installing the Nano-Tech UV Ozone System:
1. Fit the manometer (A) onto the Venturi circuit using Teflon tape. Hand-tighten the manometer.
2. Insert (B) into the outlet (C), make sure that the threaded nut (D) is as the following image displays :
3. Screw the female hose fitting (E) onto the male thread of the Venturi circuit. The other end of the hose must
be fitted into the elbow adapter, on the top of the system (F). There is a Non-Return valve (K) between (E) and
(F) which is a one direction valve to prevent air go back to the UV lamp Ozone generator.
4. Reverse the Non Return Valve will not inject Ozone to the Venturi system and
5. Joint the 3 parts (B), (D) and (L), so that the Venturi circuit and the UV system are firmly assembled.
6. Afterwards, choose at suitable place to install the assembled system, if and when it follows the order
accoring to Section 3 Typical Installation.
7. Fit the UV-C reactor with the supplied clips (H) and ensure that the 3-part couplings (B) (D) (L) are still
solilytighten. Never use a wrench, clamps or other tools whatsoever to fix the reactor.
8. The power supply wire (I) has to be connected in a way that the UV system works as the same time as the
filtrtion pump does. If not, all the UV system could get overheated.

9. Activate the pump, vent the whole system and check for any leakage in the circuit.
10. The quality of the Ozone air in the system can be adjusted by using the manual valve (J). The closer it remains,
the more Ozone will enter the circuit. The desirable range on the manometer is 9~14 psi.
11. Keep in mind: the air filtering intake (G) on the upper part of the Ozone device is intended to absorb air for
Ozone generation. It has to remain cleared. The venturi system also can be installed in vertical orientation but
the UV-C Ozone lamp body cannot be installed in vertical orientation.
