1. Decide the desired pumping range for your installation instruction. (See Fig.5 and Figure 10.) (B) is the
distance between the mounting point of attachment and the float. The distance (B), determines (A), the
desired pumping range.
2. At Distance (B), determined from Figure 10) place the cord into the clamp as shown in Fig. 6.
3. Position the float to the desired “OFF” level and secure the clamp to the discharge pipe as shown in Fig.6.
See Fig. 5 noting water line. NOTE: Do not install cord under hose clamp.
4. Tighten hose clamp using a screw driver. NOTE: Do not over tighten. Over tightening may result in
damage to the plastic clamp. Make sure the float cable is not allowed to touch the excess hose clamp
band during operation.
Notice: Do not adjust “off’’ level below discharge on pump.
5. Insert the piggyback plug from the switch into a standard grounded outlet of proper voltage. For automatic
operation, plug the pump directly into the piggyback plug. (See Fig. 7.) Pump can be manually operated
by bypassing the piggyback plug.
Notice: For installation utilizing watertight junction box or similar connections, see Figure 8.
Notice: For installation as a control switch for magnetic starter, see Figure 9.
6. Tape or clamp both piggyback switch and pump cords to the discharge pipe, clear of float operation. (See
Fig. 5.) Excess cord should be coiled and fastened outside the basin.
7. Clean basin free of debris after installation.
8. Check your installation. Fill basin with water and allow pump to cycle to insure proper range and operation.
Clarus Environmental Variable Level Pump Switches are designed for use with the appropriate voltage and horsepower, nonautomatic, single phase, Clarus
Environmental pumps. Maximum liquid temperature must not exceed 120°F for 10-0748.
Clarus Environmental Variable Level Pump Switches can be used as a control switch for a magnetic or combination starter. Maximum temperature must not exceed
140° F. See figure 9.
Single Variable Level Pump Switches are recommended for use in 18” minimum diameter pits or basins.
Note: Consult Clarus Environmental for controlling units over 1½ HP with a variable level pump switch.
