Procedure for operating sterilizer

In general, the operation algorithm of different sterilizers similar. Below described procedure for operating sterilizers JOVA UV1 and HANSUN UIV-1.3.   

Freshwater UV sterilizer JOVA UV1

Before starting up check following items:

- check voltage (230 VAC 50/60 Hz)

- fill the chamber by: opening the upper drain valve 5 (see figure below); open valve on water inlet slowly to avoid breaking the quarts-jackets; let the chamber fill up till water comes from upper drain valve 2 and close this one.

Open water inlet valve completely.

- make sure no leakage

- make sure lamps are mounted and connected

- make sure external alarm is connected in a proper way

Operation

1. Open manual valves for inlet- and outlet water.

2. Turn POWER-switch to ON.

3. The solenoid valve 4 (see figure below) is time delayed by 2 minutes for lamps to reach full output.

4. The UV-unit operates fully automatic and calls for attention if anything is wrong (internal alarm + external alarm).

4.1 Valve settings during normal operation

- close the drain valves

- open valves for inlet and outlet

- close bypass valve if there is one

The solenoid valve 4 is controlled by the control cabinet 3 (see figure below).

4.2 Control cabinet

- turn power switch ON, green diode lights up.

- all necessary information can be read in the display window. Normally available next readings UV- intensity and hour meter. Also, possible to get further information such as alarm values, total operating time by pushing arrow buttons on cabinet.

- if an alarm arise the alarm diode is lit up and the display gives you information about the error and what to do about it.

 

General view of UV sterilizer JOWA UV1

Freshwater UV sterilizer HANSUN UIV-1.3

Initial start-up

- check the power supply (power switch on control cabinet 14, see figure below)

- fill the UV vessel 13 with water

- opening the upper vent valve 2

- slowly open inlet valve, avoiding water impact to quartz and cause damage

- when water overflowed from vent valve 2, then close it

- keep inlet valve open completely

- check no leakage

Start-up

While start up the unit, it will take two minutes delay for opening of solenoid valve 4. So that the UV intensity to be warmed up to maximum outputting. After that the sterilizer running automatically.

Stop procedure is opposite to start.
