Two Float Switch System for

Features:
The Double Float^® Master pump switch is a mechanically activated pump switch which provides automatic control of pumps in non-potable water and sewage applications.  
The Double Float® Master pump switch consists of two mechanical floats and a splice tube.  The splice tube contains a holding relay which enables the floats to function in series.
The holding relay eliminates pump chatter in turbulent conditions allowing the Double Float^® Master pump switch to operate relay control panels for larger pump applications. 

The Double Float^® Master pump switch features:
• Encapsulated relay and splice provides reliable seal
• Controls pumps up to 15 FLA, 90 LRA, 120V or 240V
• Adjustable pumping range of 3 to 48 inches (7.6 to 122 cm) with increased pumping range up to 6 feet (1.8 m) available
• Floats are labeled for ease of installation
• Reliable, mechanical alternative for areas restricting the use of mercury
• CSA Certified; Three-year limited warranty


Specification:
• Cable attached to float housing: flexible  18 gauge, 2 conductor (UL, CSA) SJOW, water-resistant (CPE)
• Cable above splice: flexible 14 gauge,  3 conductor (UL, CSA) SJTW, waterresistant, thermoplastic
• FLOATS: 2.74 inch diameter x 4.83 inch long (7.0 x 12.3 cm) high impact, corrosion resistant, PP housing for use in sewage and non-potable water up to 140^oF (60^oC)
• ELECTRICAL:
  120 VAC 50/60Hz Single Phase:
  Maximum Pump Running Current (FLA):  15 amps
  Maximum Pump Starting Current (LRA):  90 amps
  240 VAC 50/60Hz Single Phase: 
  Maximum Pump Running Current (FLA):  15 amps
  Maximum Pump Starting Current (LRA):  90 amps

NOTE: This switch must be used with pumps that provide integral thermal overload protection.


Installation:
Mount the float switch:
Failure to mount floats as outlined below may inhibit switch operation.
1. Determine pumping range for installation as shown in Figures B & C.
2. If floats are mounted less than 16 inches (40.6 cm) apart, mount floats at a 90o angle from each other as shown in Figure B.
3. Place cord into clamp as shown in Figures A and B.
4. Locate the clamp at the desired activation level and secure to discharge pipe as shown in FigureA.
      NOTE: Top and bottom floats are labeled. Ensure they are mounted per Figures B & C.
5. Tighten the hose clamp using a screwdriver. 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.
6. Mount the top fl oat in a similar manner. Stow excess cable away from float operation.
7. Check installation. Allow system to cycle to insure proper operation.
NOTE: All hose clamp components are made of 18-8 stainless steel. See your SJE-Rhombus supplier for replacements.


Piggy-back plug install:
Electrical outlet must not be located in pump chamber.
Electrical outlet voltage, piggyback plug voltage, and pump voltage must match.
1. Follow steps 1 through 6 of "Mounting The Switches."
2. Insert 120 VAC piggy-back plug into 120 VAC outlet or 230 VAC piggy-back plug into 230 VAC outlet.
3. Plug pump into piggy-back plug as shown in Figure B. 
4. Check installation. Allow system to cycle to insure proper operation.










Ordering Information:
D = Pump Down  U = Pump Up  1 = 120 VAC   2 = 240 VAC  
WP = With Plug   WOP = With Out Plug
NOTE:  Descriptions are grouped by cable length measured in feet (15, 20, 30).


Options:
This switch is available:
• for pump down or pump up applications as specified by part number.    
• with a 120 VAC or 240 VAC piggy-back plug.
• without a plug for direct wiring (120 VAC units can only be used with 120 VAC applications within specified amp ratings. 240 VAC units can only be used with 240 VAC applications within specified amp ratings).
• in standard cable lengths of 15, 20, or 30 feet and 5 or 10 meters (longer lengths available).
• PACKAGING Boxed - standard; Bagged - optional; Bulk - optional
• ADDITIONAL CABLE Longer cable lengths available.  Please call for details.
