Little GIANT RFSN-6 Liquid Level Control User Manual

INTRODUCTION

The Little Giant liquid level control is designed to be used with Little Giant Effluent and Sewage pumps or other pumps rated 13 Amps or less.

Little Giant products are carefully packaged, inspected and tested to insure safe operations and delivery. When you receive your switch, examine it carefully to determine that there are no parts missing or which may have been damaged or broken during shipment. If damage has occurred, make notation and notify and/or return to the firm from which you purchased the switch and they will assist you in replacement or repair.

SAFETY GUIDELINES

WARNING

1. Read all instructions and safety guidelines thoroughly. Failure to follow guidelines and instructions could result in serious bodily injury and/or property damage.

3. Disconnect all electrical service to the pump and unplug the pump and/or switch before working on the unit or handling the unit.

ELECTRICAL CONNECTIONS

WARNING

1. The level control switch is supplied with three-prong grounding plug. The switch must be used with pumps that are equipped  with three-prong grounding plugs. Do not remove the third pin from the plug. The receptacles should be properly grounded, grounding-type receptacle.
2. Separate branch circuit is recommended. Do not use extension cord.
3. Be sure electrical connections cannot be reached by rising water. Under no circumstances should outlet box or receptacle be located where it may become flooded or submerged by water

INSTALLATION

If screw which is provided is lost, use only a #10-16 x ½” long tapping screw. Longer screws can crack the cover.

1. Attach cord clamp to pump cover as shown. The clamp and pump handle must be positioned as shown to allow free operation of float. Be sure to locate and switch power cords away from switch float.
2. A minimum tether length of 3½” is recommended for use on the #6E, #8E, #8S, #9E, #9S, 9EH, #10E, and #10S series pumps. Tether length to be 3½” when attached to pump on the #6 series pumps. The tether length is measured as shown in Figure 2.
3. A sump with a minimum diameter of 14″ is required for the #6 series sump pumps.
4. A sump with a minimum diameter of 18″ is required for the #6E, #8E, #8S, #9E, #9S, #9EH, #10E and 10S series pumps.
5. After desired tether length is established, hand tighten clamp screw.
6. For universal installation, refer to Figure 1.
   a. Attach switch cord using the cable tie provided to any convenient rigid surface about 2″ below the desired turn-on level. Do not tighten cable tie until turn-on and turn-off levels are established
   b. Increase cord length between float and tie point increases on-off differential. Decreasing cord length between float and tie point decreases on- off differential.
   c. Tighten cable tie securely after turn-on and turn-off levels are established.

CAUTION: To prevent damage to pump, do not set switch turn-off level below 2″ above bottom of pump base. Also be certain that pump is secured in position so float cannot become stuck between the pump and the basin which could prevent pump from coming on or going off. Be certain cable tie is secure so switch cord does not accidentally slip and change set on/off levels.

SWITCH ADJUSTMENTS

(approximate measurements, in inches)

TESTING Without water in sump, plug pump cord into the back of the switch

plug. Plug switch into outlet. Lift float and listen for pump to operate. Do not run pump for more than 5 seconds. Next, run water into sump where pump is installed. Fill the sump to the “on” level and allow the pump to remove water to the “off” level. Make adjustment per chart on opposite page if needed.

DIRECT WIRING

FOR DIRECT WIRING INSTALLATION, REFER TO FIGURE 3 (SCHEMATIC).

WARNING: In a 230V direct wire installation, one side of the line going to the pump is always “HOT”. This condition exists whether the float switch is “ON” or “OFF”. To avoid hazards when installing or servicing, install a double-pole disconnect near pump installation.

Check local electrical and building codes before installing. This installation must be in accordance with their regulations as well as the most recent edition of the National Electrical Code Handbook (NEC).

MANUAL PUMP OPERATION POSSIBLE BY PLUGGING PUMP DIRECTLY INTO OUTLET. (Plug configuration may vary depending on voltage.)

NOTE: Little Giant Pump Co. cannot be responsible for damages caused by the faulty or negligent installation of this control. If you feel that you may encounter problems in installing this device, we respectfully suggest you engage the services of a competent plumber, electrician, or qualified service person.

ADDITIONAL INFORMATION

CAUTION: To prevent damage to pump, do not set switch turn-off level below 2″ above bottom of pump base. Also, be sure that the pump is secured in its position so the float will not become stuck between the pump and the basin, which could prevent the pump from turning “ON” or “OFF”. Be sure the cable tie is secure so the switch cord does not accidentally slip and change the pre-set ON/ OFF levels.
