Application: The CSP- , CSP-257, and CSP-457 crawl space pumps are designed for use a crawl space or where pooling water 237 in
is occurring. Allowing the water in the pump or discharge line to freeze may cause damage to the pump. In colder regions, the pump
should only be installed indoors or deep enough to be below the frost line.
A. For in ground installation a hole should excavated as small as possible, leaving at least 8” of diametrical clearance. BACKFILL:
Course gravel is recommended for backfill.
B. The CSP- , CSP-257, and CSP-457 include a perforated basin for gathering water. Additional inlets may be added with INLET: 237
a hole saw for allowing drain lines or weep tiles.
C. When attaching the discharge, place the pump in the basin being careful to keep float from any obstruction or from DISCHARGE:
hitting the tank wall. The CSP- , CSP-257, and CSP-457 include a DHK-24 discharge hose kit. A 1-1/2” X 1-1/4” hose adapter 237
will thread into the pump discharge. The 24’ flexible hose will fit over the barbed fitting of the adapter and should be tightened
down with a hose clamp. The hose will fit through the grommet in the basin cover and can be cut to the required length. Exit the
discharge of water in an area that will drain away from the building and foundation.
D. The CSP- , CSP- and CSP-457 include a threaded check valve for use with the discharge hose. If the CHECK VALVE: 237 257,
pump is short cycling, then a check valve may be required. This would prevent water from draining back through the discharge
hose into the basin. When using a check valve, the discharge line must be protected from freezing by running the discharge deep
enough below ground level to be beneath the frost line. See figure 1.
E. The pump power cord is equipped with a grounding conductor and grounding-type 3-prong plug. It should be POWER CORD:
connected to a separately fused, grounded, 3-wire grounding-type receptacle of 15-amp capacity with the proper . Make sure 115V
all electrical wiring and connections are in accordance with the National Electric Code and all applicable local codes.
Risk of electric shock. Always disconnect the pump from the power source before handling or making adjustments.
DO NOT remove the plug or ground prong.
DO NOT use an extension cord.
