DESCRIPTION

The Myron L Controlstik Rinse Tank System is a fully automatic
control which will greatly reduce the amount of water used in
continuous flow rinse tanks. At the same time, it automatically
maintains water quality, ensuring effective rinsing in water up to
180°F (82°C). It operates on the electrical conductivity principle
and is fully stable and protected against all environmental
conditions including temperature, line voltage, water
contamination and corrosion.

After installation, the Controlstik (sensor) is submerged in the
rinse water. When contamination (dragin) accumulates beyond
the point “safe” for good rinsing, the sensor automatically opens
the Solenoid Valve. Fresh water flows into the tank, and as
excessive contamination is diluted back to the “safe” level, the
sensor closes the valve, limiting water use.

INSTALLATION AND OPERATION PROCEDURES

A. Mounting

1. Transformer Box
NOTE: 115 VAC Models, see Section C.1 before

proceeding.

CAUTION: Do not apply power until all wiring has been

completed and connections checked.

a.For panel mounting, cut 3.96 in. (101 mm) x 5 in.

(127 mm) hole in panel (template on back page can
be used). Drill two holes in panel. Holes should be
.089 in. (2.3 mm) if using self-tapping screws; .113 in.
(2.9 mm) if using bolts/ nuts provided. Attach to panel
through lower (without brass inserts) box flange
holes.

b. If surface mounting, first attach the supplied Surface

Mounting Plate to the rear of the transformer box
with the two (2) 1/4" - 20 screws provided. Use
appropriate screws or bolts (not provided) to then
mount the box/plate assembly to a suitable surface.

c. Following electrical connections detailed below, front

face plate is snapped on (gasket seal requires some
pressure) and attached using black screws
(provided).

2. Controlstik Sensor
Hang Controlstik (sensor) in the tank by the cord, using the

secured clamp to hold the cord onto the edge of the tank.
The sensor should hang vertically, fully submerged at least
4 inches (100 mm) off the tank bottom and not closer than 2
feet (61 cm) to the inlet water line. If tank is small, locate
sensor at end opposite from inlet.

NOTE: If water rate is slow or if dragin rate and concentration

prevent good diffusion of contamination … the following
should be considered to ensure the Controlstik senses

water which is “representative” of the entire tank:
a. Agitation — by air or other means
b. Installation of weir in tank perpendicular to water flow
c. Use of spider (sparge) on inlet

B. Piping

1. Install valve in inlet water line to rinse tank so that flow
direction is as indicated by the arrows on the top of
valve body.

2. Use Teflon tape on all connections and plug the unused
inlet.

3. Ensure flow control is at least partially open by turning
counterclockwise.

NOTE: The 1-inch NPT valve supplied requires at least 10 psi

(69 kPa) line pressure to operate. Increasing flow rate
may allow valve to operate at lower pressure.
