Biosan UVR-M User manual

The following spare parts are available for UVR-M:
Periodical maintenance
UVR-M does not require periodical technical maintenance, except cleaning.
Cleaning. Standard ethanol (75%) or any other cleaning liquids can be used for cleaning
and disinfecting of the device, if it does not contain any strong organic solvents (such
as acetone, toluene or benzene).
In order to ensure proper efficiency in the long term run it is recommended to clean the
UV-recirculator and dust filters once a month. To do so unscrew the twelve screws on
the rear panel, take off the panel and blow off dust from the lamps and reflectors
preferably by compressed air to ensure integrity of reflective coating.

II. Electrical Safety tests
With the unit disconnected from the AC power supply, and the power supply lead plugged
into the unit, perform the following safety tests before returning the unit to the customer.
- Earth Bonding Test
Use a low resistance measuring instrument to check that the resistance between unit
chassis and power cable earth connector is less than 0.1 ohm.
- Insulation Resistance Test
Connect the live and neutral pins of the power supply plug together. Use a 500V
insulation resistance tester and measure the insulation resistance between the earth and
live/neutral pins. This should be greater than 2 Mohm.
