D. General Care and Maintenance
• The unit should be disconnected from the power
source prior to cleaning.
• Before use, clean and dry the apparatus with
DISTILLED WATER ONLY.
DO NOT use abrasive pads, cleaners, creams or scour-
ers. Dry components with clean tissues prior to use.
The cabinet should not be used on or above surfaces
cleaned with aromatic or halogenated hydrocarbons,
ketones, esters, alcohol’s (over 25%) and acids (over
25%) or where such compounds have been used
because of the risk of vapors damaging the acrylic.
There are no internal operator serviceable parts in
this unit. If the power should fail, the unit must be
returned to the authorized service center.
E. Replacing the Lamps
Over time, the lamps will diminish in their output.
It is therefore recommended that all the lamps are
changed at the same time, for uniform efficiency.
Please use a qualified safety engineer to replace and
check the operation of the lamps.
1. Remove the power cord from the back of the unit.
2. To remove the lamps open both safety doors
fully and using both hands, twist the lamps one
quarter turn. The lamps will then come out of
their sockets.
3. To insert new lamps, place the lamps in their
sockets and twist them until they fix in position.
4. Replace the power cord and have the cabinet
checked by a qualified safety engineer.
IMPORTANT: Acrylic plastic is
NOT resistant to aromatic or
halogenated hydrocarbons,
ketones, esters, alcohol’s (over
25%) and acids (over 25%).
They should NOT be used for
cleaning.
CAUTION: The lamps become
very hot during use. Make
sure that the lamps have
cooled down before removing
them.
