I. PUMP CONNECTIONS & INSTALLATION INSTRUCTIONS
WARNING: IMPROPER INSTALLATION WILL VOID WARRANTY.
1) Select proper jacketed cable size (Fig.1).
Note: DO NOT select cables with
irregular shapes, rough or
grooved surfaces.
Use a #10 AWG jacketed Submersible
cable that fits into the general size
requirements shown (Fig 1).
2) Assemble Cable Boot (Fig. 2, 3, 4).
a) Strip the outer cable jacket (Part A - not included) 2.0 in. (5 cm) (Fig. 2).
b) Cut one of the lead wires 1.0 in. (2.5 cm) (Fig. 3).
c) Wrap electrical tape around the cable. Start 2 in. (5 cm) below outer cable jacket
and continue to taper a point past the end of lead wires (Fig. 4).
Generously lubricate the cable 4 to 6 in. (10 to 15 cm) with supplied O-Ring grease.
d) Slide the cable boot components over the cable (Part A) in the following order (Fig. 4).
1) Nut (Part D). Make sure threads are toward pump end of cable.
2) Outer Cable Boot (Part C). Small end first.
NOTE: Re-lubricate cable as necessary.
3) Inner Cable Boot (Part B). Small end first.
e) Remove tape and cut the lead wires back leaving about .50 in. (1.3 cm) exposed.
Strip the inner conductor jacket .50 in. (1.3 cm) (Fig. 5).

f) Insert the wire leads into Plug (Cable Adapter) connectors.
Using a 5/64" Allen Wrench tighten the set screws (Fig. 6).
g) Slide the Inner Cable Boot (Part B) over the plug until it is flush with
the first step on the collar (Fig. 6).
Wipe the grease from the surface of Inner Cable Boot and cable.
Tape end of Inner Cable Boot tightly to the cable.
Be sure to tape 4 in. (10 cm) below the Inner Cable Boot on the cable.
Note: This taped area allows the Outer Cable Boot (Part C) to slide freely over the Inner Cable Boot.
DO NOT REMOVETHETAPE.
h) Lubricate the outer surface of the Inner Cable Boot and tape with supplied O-Ring grease.
Slide the Outer Cable Boot (Part C) over the Inner Cable Boot until it is flush with
the second step on the collar (Fig. 6).
i) Push the Plug (Cable Adapter) into the Receptacle (Cable Adapter) until the collar is seated flush.
NOTE: The orientation of the Plug(Cable Adapter) will not effect the pumps performance.
j) Push the Nut (Part D) over the Plug (Cable Adapter) and then finger tighten the nut.
NOTE: Before continuing, operate the pump to check all electrical connections,
using the correct power supply. Refer to Technical Specifications (Pg. 14).
If pump does not operate Refer to "Helpful Hints" (Page 8) before continuing .
3) Install the 6 in. hose and fitting (1/2" NPT X 1/2" BARB) (Fig. 7, page 5).
a) Press the fitting into the 6 in. hose, slide the clamp on the hose and over the fitting and tighten the clamp securely.
b) Slide another clamp on the 6 in. hose, slide the assembly over the barbed fitting on the pump,
and tighten the clamp securely.
Note: Select the proper adapter hose and accessories for the pump.
USE OF DISCHARGE PIPE LARGER THAN 3/4" IS NOT RECOMMENDED..
Use 150 P.S.I. Min. (10 bars) working pressure rated 1/2 in. I.D. (12.7 mm I.D.) smooth bore hose (Part not included.).
Use All-Stainless Steel hose clamp (Part not included.

lift plate holes.
b) Fasten line with appropriate connection
approximately 1-2 ft (30 - 60 cm) above the pump.
5) Band the Hose, Safety Line, and Electrical
Cable (Fig. 8).
Tie the drop lines together using tie wraps
every 6ft. (1.8 m).
This banding will prevent unnecessary damage to the
lines during Installation and Removal of pump.
6) Install Pump (Fig. 8).
Note: Prior to installing the pump, fill in the application worksheet
on pages 14-15.
The application worksheet is a guide to make sure that the pump is
installed properly in the well.
Following the guidelines laid out in the application worksheet will
allow the pump to perform efficiently and extend the life of the unit.
Refer to "Helpful Hints" if you experience any difficulties.

WARRANTY
LIMITED WARRANTY PROCEDURE
SINGFLO warrants its pump to be free of defects in material and workmanship to the original retail
purchaser for the period of one year beginning with the purchase date of the unit or, in the absence of
proof of purchase date, one year from the date of manufacture as shown on the pump, not to exceed
two (2) years in any event. Each pump has been operated and tested before being shipped from
SINGFLO's factory. During the warranty period if the pump is not operating correctly, you may return it
freight pre-paid to your local distributor, dealer or directly to SINGFLO.
Upon SINGFLO's inspection, any unit found faulty due to manufacturing defects will be repaired or
replaced at no charge. This warranty does not apply to any damage resulting from misuse, negligence,
accidents, improper installation or wiring. Abuses such as removal of the SINGFLO label, improper
repair, installation, application, or damaged lower housing assembly due to running dry, are also not
considered warrant able. There will be charges applied for any of the above mentioned non-warrantable
items.
If you send the pump to us for prompt repair, please package it carefully to avoid shipping damage.
Enclose your name, address, a phone number where you may be reached and your proof of purchase
date.
The above represents our warranty policy. Under no circumstances will we assume or accept
responsibility for unauthorized expenditures, losses, or any costs greater than the basic pump value.
