6.3 Cleaning and Maintenance Tasks - UV-O 1000
It is a matter of experience to determine when your UV-O 10 00 Unit needs to be cleaned
as the nature and degree of any pollution depends strongly on factors such as the
particular location, humidity and the intensity of use etc. Nevertheless, the UV lamps
should be cleaned and the inside of the Units cleaned regularly, at intervals not exceeding
3 months, using the procedures outlined in the sections below:
6.3.1 Cleaning the UV-O 1000 Lamps
To clean the UV-O 1000 lamps:
1. Isolate the Unit from the mains power supply by turning the Rotary Mains Isolator
Switch to the ‘Off’ position.
2. Double check that the mains power supply has been isolated.
3. Undo the lock, unscrew the four Star Knobs anti-clockwise on the Front Panel and
open it.
4. Slide out the UV Lamp Holder on the Runner System (See Figure 28 - Lamp Holder
and Runner System on page 27).
5. Carefully remove plugs from the end of the lamps (See Figure 28 - Lamp Holder and
Runner System on page 27).
6. Remove the lamps from their clips (See Figure 28 - Lamp Holder and Runner
System on page 27).
7. Clean the lamps by wiping them with alcohol wipes or a lint free cloth soaked in
isopropyl alcohol and dried with a lint free cloth.
Note: Natural oily deposits left by fingers and palms create an opaque mark on
the lamp thereby reducing the UV transmission. These marks also cause
the quartz to break down, causing premature lamp failure. Use caution
when cleaning near the ends of the lamps excessive pressure may remove
or smear the coating protecting the lamp electrodes.
It is a matter of experience to determine when the UV lamps need to be cleaned, since
the nature and the degree of pollution depend strongly on factors such as the particular
location, environmental conditions and intensity of use, etc.
Note: Whatever the situation, however, the UV lamps should be cleaned regularly
according to the schedule outlined in (See 6.1.1 Maintenance Schedule UV-O
500 and UV-O 1000 on page 33).
6.3.2 Replacing the UV-O 1000 Lamps
1. Replace the lamps in their clips (See Figure 29 - Lamp Clips on page 28).
2. Replace the plugs on the end of the lamps (See Figure 3 0 - Lamp Plugs on page
28).
3. Slide in the UV Lamp Holder on the Runner System (See Figure 28 - Lamp Holder
and Runner System on page 27).
4. Close the Front Panel, screw the four Star Knobs clockwise to tighten them and
fasten the lock.
