Puranity TU+ VWR
Chapter 13
6 CAUTION
When you are removing the
UV lamp you must ensure
that the glass of the UV lamp
is not soiled or that you do not touch it with
your fingers. This could impair proper
functioning of the lamp. We therefore
recommend that you wear clean, disposable
gloves when performing this work.
CAUTION
When installing a new UV
lamp ensure that the flat seal
ring and the O-ring are on
the correct position. The flat seal ring must
fit exactly in the groove provided for it on the
top of the union nut (figure 1 and 2). The
O-ring fits in the bottom groove in the union
nut (figure 1). If these items do not fit exactly
in the grooves and you restart the system,
the UV assembly will not be leak-tight at
these locations.
a. Now, carefully rotate a new UV lamp
into place by turning it in a
counter-clockwise direction into the
UV assembly (figure 3).
b. You can then re-attach the plug to
the UV lamp and retighten the UV
assembly on the mounting plate
using the two retaining brackets and
the two screws that you removed
previously.
