The Visuguard LCD is particularly recommended in show-
ers and shower bath installations for motels, hotels, dormi-
tories, health care facilities, and single family residences.
Operation (SeeFigure 1)
n
Hot and cold water enter their respective ports and the
flow of water is equalized through the action of the bal-
ance poppet (1). The entire balancing poppet assembly
is contained in a Celcon chamber (2). This chamber is
replaceable as a complete cartridge. After the hot and
cold flows are equalized, they are mixed by the action of
a mixing plate (3). As the temperature adjustment stem is
rotated from shutoff to maximum hot water temperature,
the mixing plate passes the required proportion of hot and
cold water to produce the control point. With the adjust-
ment stem in its full clockwise position, shutoff is obtained
by closing both supplies.
The maximum temperature stop (4) allows the user to set the
maximum discharge temperature. This mixer does not rec-
ognize supply water temperature changes, so any variation
in the water temperature will affect the control point
and the
maximum temperature setting.
NOTE: Following any maintenance of unit, maximum tem-
perature stop must be reset. See page 4 for instructions.
