1.0 PREFACE
This manual has been written to present the basic installation
and operational characteristics of the VANGUARD Wash
Max.
This manual applies, in its entirety, to current units.
Guidelines will be suggested in reference to the preferred
method of installation, however, the variety of equipment and
the surrounding physical environment will dictate the actual
installation of the VANGUARD Wash Max
WARNING - These installation and servicing in-
structions are for use by qualified personnel only.
The installation must be made in accordance with
local plumbing and electrical codes.
The VANGUARD Wash Max Reservoir is a system de-
signed to convert solid or powdered warewashing detergent
into a high strength liquid for dispensing into the wash tank
of a dishmachine. The system consists of a reservoir,
possibly a Guardian Kit or a Power Activator Kit and is used
in conjunction with the VANGUARD EcoCenter, Control
Max, VANGUARD 2026, Senso-Matic 26 electronic control,
or the Centron.
The VANGUARD Wash Max Reservoir consists of a heavy
duty reservoir for holding a solid detergent or powder, a
vacuum breaker, tubing, an empty capsule light, a cover
safety switch and a spray nozzle located at the bottom of the
reservoir. The reservoir will hold one capsule of solid deter-
gent or up to 6 pounds of powdered detergent.
2.1 Principle of Operation
The basic principle of operation of the VANGUARD Wash
Max Reservoir is that it converts solid or powdered
warewashing detergent into an extremely high strength
liquid and directs this liquid into the wash tank of a
dishmachine. Product capsules or powder are added to the
dispenser supply compartment by lifting the lid of the reser-
voir and inserting the capsule or pouring the powder.
A solenoid valve, activated by the concentration control unit,
allows water to flow through the vacuum breaker to the
spray nozzle. The nozzle is designed to apply a uniform
spray pattern to the product surface. The solid detergent
dissolves and flows, by gravity, into the dishmachine wash
tank.
When the conductivity sensor in the wash tank senses the
need for more product, the VANGUARD EcoCenter, Control
Max, VANGUARD 2026, Senso-Matic 26 or Centron Model
526 opens the 24 volt AC solenoid valve allowing water to
flow to the VANGUARD Wash Max Reservoir through the
vacuum breaker to the spray nozzle. The nozzle is de-
signed, to apply a uniform spray pattern to the product
surface. The solid detergent dissolves and flows, by gravity,
through tubing into the wash tank of the dishmachine. When
the conductivity sensor in the wash tank senses an ad-
equate detergent strength, the VANGUARD EcoCenter,
Control Max, VANGUARD 2026, Senso-Matic 26 or Centron
Model 526 closes the solenoid valve.
