SAFETY PRECAUTIONS

About this Manual:

PLEASE READ THE ENTIRE MANU-

AL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on the Switch Pak™ with Compact
Relay Controller: AU15-_24_, AZ18-_24_ and AV16-_24_. The
units are identical except for the material of construction and the
sensors technology.

User's Responsibility for Safety:

Flowline manufactures

a wide range of liquid level sensors, controllers, and mounting sys-
tems. It is the user's responsibility to select components that are
appropriate for the application, install them properly, perform tests
of the installed system, and maintain all components. The failure to
do so could result in property damage or serious injury.

Proper Installation and Handling:

Use a proper sealant

with all installations. Never overtighten the components. Always
check for leaks prior to system start-up.

Material Compatibility:

Polypropylene (PP, a polyolefin): Sensor, Switch Pak™ fitting,
Controller Housing.

Polyvinylidene Fluoride (PVDF): Sensor and SWitch Pak™ fitting.

Viton (a fluorocarbon): O-ring.

Make sure that the application liquids are compatible with the
materials that will be wetted. To determine the chemical compati-
bility between the components and its application liquids, refer to
the Compass Corrosion Guide, available from Compass
Publications (phone 858-589-9636).

Temperature and Pressure:

Switch Pak™ is designed for

use in application temperatures up to 90° C (194° F). The Vibration
and Ultrasonic packages are designed for pressurized applications
up to 150 psi (10 bar) and the Buoyancy package is designed for
use up to 25 psi (1.7 bar).

Wiring and Electrical:

Electrical wiring of any liquid level

control system should be performed in accordance with all applic-
able national, state, and local codes. Take care not to cut or break
the outer insulation jacket of wiring that may be immersed while
routing cables in the Switch Pak™ system. Such breaks of the liq-
uid seal of the sensor system may lead to component failure.

Flammable, Explosive and Hazardous Applications:

Switch Pak™ may be used within flammable or explosive applica-
tions only if the associated components are rated intrinsically safe
for such use. In hazardous applications, use redundant measurement
and control points, each having a different sensing technology.

Make a Fail-Safe System:

Design a fail-safe system that

accommodates the possibility of system or power failure. In criti-
cal applications, Flowline recommends the use of redundant back-
up systems and alarms in addition to the primary system.

About Switch Pak™:

Flowline’s Switch Pak™ with Compact

Junction Box Assembly is an single-point mounting system for
installing one level sensor vertically within a tank. The compact junc-
tion box features termination for the various wires from each level
switch as well as a 1/2” conduit connection. Switch Pak™ mounts
vertically through a standard 2" NPT tank adapter, or on a side mount
bracket (such as the LM50-1001).

Level Switches:

Switch Pak™ includes

a single level switch used to identify it’s own
unique wet / dry condition. The technologies
used to indicate level are either Ultrasonic,
Buoyancy or Vibration. Each technology fea-
tures a unique wiring/power configuration
(Ultrasonic and Vibration technologies
require 12 to 36 VDC power for operation,
see below). The switch is terminated in the
Compact Junction Box. The Compact
Junction Box provides a 1/2” Conduit con-
nection and 6 poles for wire termination.
