10. Connect into the M4 socket cap and tighten the socket cap so that the glass filter is held securely.
11. Check the glass filter and reconnect the power to the unit.
12. Please wait eight minutes before switching the unit back on.
Replacement Glass Filters
The front glass is specifically designed to permit the transmission of specific wavelengths of light. The nature of UV is that the glass filters will
naturally suffer from ‘solarisation’, which means that they lose the ability to control the passage of UV-A and UV-B and will deteriorate over
time. In order to maintain the unique performance of the UV420, we recommend that the glass filters be replaced as follows:
1. ‘Blue light & UV-A’glass filter (white frame) after 24,000 hours of use or 4 years.
2. ‘Enhanced UV-B’glass filter (red frame) after 12,000 hours of use or 2 years.
3. ‘Enhanced UV-A’glass filter (blue frame) after 12,000 hours of use or 2 years.
Always source replacement glass filters from Ceravision or an authorised Ceravision distributer. The use of non-Ceravision authorised glass
filters in the unit will invalidate the Terms & Conditions and Warranty. When ordering replacement glass filters please specify the exact unit
description and glass filter type, e.g. UV420 and the particular glass filter that you require.
Cleaning and Maintenance
External factors such as dust and moisture may cloud the glass and reduce the efficiency of the unit. The unit would therefore benefit from
routine cleaning of the glass. Do not carry out maintenance or cleaning whilst the unit is connected to the mains; disconnect all power and allow
to cool prior to cleaning.
The outside of the unit and the glass can be cleaned using non-abrasive household cleaning materials. Use of abrasive materials may damage the
glass and will invalidate the warranty. Take care not to damage or contaminate the glass filter during cleaning.
During routine cleaning, the unit should be checked for any signs of damage.
Opening the unit itself will invalidate the warranty.
Working with UV
Ceravision’s UV420 unit is an intense light source, which emits UV-A, UV-B and visible light. The unit should never be operated with the light
source directly visible. The reflector housing and glass filter should always be correctly positioned and fitted in the unit at all times during its
operation.
The unit should not be used if the front glass filter is broken or cracked. Check the unit prior to installation and continue to do so during cleaning
and routine maintenance. If the glass filter becomes damaged during use, disconnect the power source immediately and do not use the unit until
the problem is rectified and replacement found.
When working with these units, users MUST be protected from exposure to harmful levels of radiation. Those working with UV-emitting light
sources should be trained in the potential hazards and in the use of suitable protective equipment to prevent harmful exposure.
We recommend you refer to the following HSE publications: ‘Guidance for Employers on the Control of Artificial Optical Radiation at Work
Regulations (AOR) 2010’; and ‘Reducing Health Risks from the use of Ultra-Violet Tanning Equipment’.
We recommend that full body coverage and UV blocking protective glasses be worn in areas where the units are operating. When working with
UV emitting sources, users are recommended to monitor UV levels using appropriate UV-A and UV-B meters and adhere to the exposure limit
values; these are normally displayed as a maximum exposure time in each case.
Further advice on UV safety and UV monitoring equipment is available from UV Light Technology, see www.uv-light.co.uk
High Temperatures
The UV420 unit can reach temperatures in excess of 190oC. Allow to fully cool before handling.
