NOTE: Switch not for use for direct “on/off” pump operation. Must be used with control panel.
CABLE WEIGHT (See Sketch #2)
1. Lay cable in weight channel.
2. Align clip with weight groove and slide towards cable.
3. Snap clip snugly up to cable, manually moving clip to the tightest possible position.
4. Wire cable leads directly into control device.
5. Suspend unit at desired activation level.
All installation of controls, protection devices and wiring should be done by a qualified
licensed electrician. All electrical and safety codes should be followed in addition to the most recent
National Electrical Code and the Occupational Safety and Health Act (OSHA).
1. Determine your “on” level. (See illustration above) For pump down (NORMALLY OPEN) application: The variable level
control switch closes (turns on) when the float tips a few degrees above the horizontal position and opens(turns off)
when the float drops a few degrees below the horizontal position. This mode is regularly used on pump applications.
For normally closed applications only: The variable level control switch closes (turns on) when the float drops a
few degrees below the horizontal position and opens (turns off) when the float tips a few degrees above the horizontal
position. This mode is used to maintain a specific fluid level in container when pumping from another source. (i.e. stock
watering tank)
2. If cable weights are not being used, strap variable level control switch to discharge pipe or similar mounting at determined
on-off level. (See sketch #1) NOTE: Do not install cord under hose clamp. NOTE: Be sure float is positioned so that
it will not be restricted in its movement by any item in the pit. The strap clamp should be a minimum of 3” from any top
restriction (pit cover) or 9” from any bottom restriction (floor, pump, etc.).
3. If cable weights are used, adjust tether as shown in sketch. (See sketch #2)
Notice: Do not adjust “oFF” level below discharge on pump.
Use control switch in panel controlled pump applications only.
