We appreciate your business! Please take a few minutes to familiarize yourself with your FLR and this manual. The FLR contains up to seven reed switches in a 1/2" Ø stainless steel stem and permanent magnets in the floats. As each float rises or falls with the level of the liquid, the magnet inside the float acts on the corresponding reed switch inside the stem to provide SPST switching action. Reading your label Every APG instrument comes with a label that includes the instrument's model number, part number, serial number, and a wiring pinout table. Please ensure that the part number and pinout table on your label match your order. iii WARRANTY AND WARRANTY RESTRICTIONS This product is covered by APG's warranty to be free from defects in material and workmanship under normal use and service of the product for 24 months.

If a stilling tube is used, drill vent holes in the tube and use a spacer to assure the float has free travel inside the tube (See Figure 2.1). · The FLR can be mounted up to 30° from vertical. Inflow Stilling Tube Inflow 30° 30° Spacer 30° Figure 2.1 Mounting Instructions 1. Flange Mounting Provide the compatible mating flange on the tank and install using a suitable gasket. 2. Plug Mounting Provide the compatible female boss on the tank and install the FLR with a suitable gasket, O-ring, or thread tape. 5 Electrical Installation · Check the Wire Color Diagrams and Table on page 4 before making any connections. · Connect the wire(s) for each switch to your system. · Where neccessary, make junction box or conduit connection to 3/4" NPT threads above FLR mounting. · For inductive loads or high voltage/high current resistive loads, provide circuit protection for switch(es) (See Figure 2.2). See Specifications on page 2 for switch ratings. Protecting Circuit Using Diode Protecting Circuit Using Varistor Protecting Circuit Using CR E L R C Figure 2.2 C = 2I/10 (uF) R = Approx. 10 x I E (I + 50/E) MPORTANT: DO NOT EXCEED CONTACT RATINGS! A back electromotive force of several hundred volts (energy stored in the inductance) arises when the contacts are opened. under inductive loads or high/voltage/high current resisteive loads. This results in considerable decrease in contact life. Removal Instructions Removing your FLR from service must be done with care. · Ensure all switch ciruits are de-energized. · Disconnect all switch circuits. · Remove the FLR with an appropriately sized wrench (per your mounting type). · Clean the FLR's stem and floats of any debris (see General Care) and inspect for damage. · Store your FLR in a dry place, at a temperature between -40° and 100°C (-40° and 212°F). 6 CHAPTER 3: MAINTENANCE General Care Your FLR series stem-mounted multi-point float switch is very low maintenance and will need little care as long as it is installed correctly. However, in general, you should: · Periodically inspect the stem and floats for any trapped debris, sediment, or other foreign material. · Avoid applications for which the FLR was not designed, such as extreme temperatures, contact with incompatible corrosive chemicals, or other damaging environments. · If your FLR has an NPT mount, inspect the threads whenever you remove it from duty or change its location. IMPORTANT: The switch points on an FLR with no housing CANNOT be moved, changed, or adjusted. 7 Automation Products Group, Inc.
