A qualified electrician must perform all the
wiring.
CAUTION
1. GENERAL INFORMATION
1.1. Read this Instruction Manual thoroughly prior to any work.
Work should be undertaken by qualified persons only.
ATTENTION!
Important information for installers of
this equipment!
This equipment is intended for installation by technically
qualified personnel. Failure to install it in compliance with
national and local electrical codes, and with motor suppliers'
recommendations, may result in electrical shock or fire hazard,
unsatisfactory performance, and equipment failure. Installation
information is available from pump manufacturers and directly
from motor suppliers. Retain this information sheet with the
equipment for future reference.
WARNING
Serious or fatal electrical shock may result from failure to
connect the motor, control enclosures, metal plumbing, and all
other metal near the motor or cable, to the power supply ground
terminal using wire no smaller than motor cable wires. To reduce
the risk of electrical shock, disconnect the power before working
on or around the water system.
2. LOCATION
The pump should be installed in a dry, accessible place not
subject to freezing temperatures. If installed in a pump pit or
another location subject to dampness, proper ventilation must be
provided to avoid moisture damage to the electrical equipment.
3. PIPING
Galvanized steel or plastic pipe is recommended. If copper
or other dis-similar metal piping is used, a dielectric union or
bushing is recommended where the piping is connected to the
pump body. The pipe used should be cleaned and free of scale.
Ream ends of the pipe to remove burrs. Check threads to see that
they are clean and not damaged. Horizontal runs of the suction
pipe must slope upwards from the well to the pump to avoid air
pockets in the line which will make it difficult, if not impossible,
to prime the pump. The recommended slope is one inch in ten
feet. If the pump must be offset an appreciable distance from
the well, the size of the horizontal pipe should be increased to
reduce friction losses.
In the case of using dielectric bushing, insert bushing into the
female end of the pump housing (or other female connection) by
hand. Use a six-sided socket to tighten the bushing.
The bushing should be fully inserted into the female connection.
After the male end of the bushing is fully installed, insert the pipe
(or other male connection) into the female end of the bushing by
hand. Failure to follow these guidelines may damage the bushing.
Caution should be taken to not cross-thread the bushing.
4. FLUSHING
If the pump discharge line is connected to a pressure tank or
house service, disconnect it, flush and clean the system by
temporarily wasting the water outdoors or draining it. The pump
should be operated until the water runs clear, without sand, mud,
or rust.
This procedure will eliminate the danger of pumping dirty water
into the pressure tank and home appliances. When water runs
clear, re-connect the discharge line to the tank and service.
5. WIRING (Use copper conductors only)
Make sure that wires and fuses of the correct size are installed.
Make sure that the phase, voltage, and cycles of the supply
circuit are the same as those shown on the motor nameplate.
It is strongly recommended that a separate electric line, well
protected against fire, be run from the electrical service to the
pump, with a fused switch box at the pump.
In the event of a fire, this precaution will permit the continuous
operation of your pumping system. For added safety, the pump
and motor should be properly grounded to the well casing or to a
separate ground rod driven eight feet into the ground.
NOTE: For proper fuse, circuit breaker and wire sizes in your
area, follow local codes. Otherwise:

* Time delay fuses and circuit breakers (Single Phase).
For distances of 100 feet and over from motor to motor, a larger
wire than shown may be required.
6. MOTORS
Motors are equipped with sealed ball bearings and require little
attention. If the motor repeatedly stops, cools off, and starts
again, the cause of the problem must be located and corrected.
Do not cover the motor with canvas or other materials that may
interfere with proper air circulation and cause overheating.
7. PRESSURE SWITCH
The factory sets the pressure switch to start the pump at 30 PSI
and stop it at 50 PSI. If a change is necessary, remove the switch
cover and adjust either the operating pressure or differential
between start and stop (if available) by turning the screws,
marked on the switch, in the required direction. Wiring directions
given on the pressure switch may damage the bushing. Caution
should be taken to not cross-thread the bushing.
