1.This unit can be installed in sump pit with min- imum diameter of 12"(30cm) and depth of 12" (30cm). Sump pit may be constructed of tile, concrete, steel or plastic. Check local codes for approved materials.

2.Install pump on solid, level foundation, as near as possible to center of sump pit. Do not hang pump from discharge pipe or power cord.

Pump must be level (column must be vertical) when oper- ating. If motor is tilted, internal start/run switch

may overheat and damage motor.

3.Pump should not be installed on clay, earth or sand surfaces. Clean sump pit of small stones and gravel which could clog the pump. Keep pump inlet screen clear.

4.Thread discharge pipe into pump body careful- ly to avoid stripping or crossing threads. NOTICE: Do not use ordinary pipe joint com- pound on plastic pipe or pump. Pipe joint com- pound can attack plastics and damage pump.

5.To reduce motor noise and vibrations, a short length of rubber hose (1-5/8"(41mm) I.D., e.g. radiator hose) can be connected into discharge line near pump using suitable clamps.

Risk of electric shock. Pump is designed for 115V., 60 HZ

operation and requires an individual branch circuit of 15 amperes capacity. It is supplied with a 3-wire cord set with grounding-type plug for use in a 3-wire, grounded outlet. Do not cut off the round grounding prong. For safety, outlet must always be electrically grounded to a suitable electrical ground such as a grounded water pipe or a properly grounded metallic raceway or ground wire sys- tem.

6.Locate Float Rod Guide (Key No. 6) about 6" (16cm) below motor. Clamp guide to column with screw provided.

Risk of flooding. Be sure that guide is securely clamped so

that float rod is vertical and can move up and down freely. If float is angled or binds, pump may not start, allowing flooding to occur.

7.Screw float onto threaded end of rod. Threads on rod will cut threads into corrosion resistant float.

8.Insert plain end of float rod up through eye of rod guide.

9.Slide one rod stop on float rod before passing rod through eye of pump switch. Slide 2nd rod stop on rod after passing through eye of switch. Position 2nd rod stop flush with top of rod.

10.Position lower rod stop to within 8"(20cm) of switch lever arm. With lower rod stop in this position, pump will automatically cycle at approximately 2-1/2"(6cm) off and 10-12"(25- 30cm) on. For faster cycling, move lower rod stop closer to switch lever arm.

11.If pump discharge line is exposed to outside subfreezing atmosphere, then portion of line exposed must be installed so any water remain- ing in pipe will drain to outfall by gravity. Failure to do this can cause water trapped in discharge to freeze which could result in dam- age to pump.

12.Install an in-line check valve to prevent flow backwards through pump after pump shuts off. NOTICE: Simer check valves are equipped with an air bleed hole to prevent airlocking the pump. If using a check valve that is not a Simer valve, drill a 1/8" (3.2mm) hole in discharge pipe just above pump body but below the check valve to prevent air locks.

13.After all piping and controls have been installed, unit is ready for operation.

14.Run pump through one cycle to check float switch operation.

The pump motor is equipped with automatic resetting

thermal protector and may restart unexpected- ly. Protector tripping is an indication of motor overloading as a result of operating pump at low heads (low discharge restriction), exces- sively high or low voltage, inadequate wiring, incorrect motor connections, or a defective motor.
