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.
ELECTRICAL CONNECTIONS
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.
