AY McDonald Sump Manual Revised 3-11
3210-418

Carefully read and understand all of the warnings and installation instructions in this
manual. Failure to follow these instructions could lead to serious bodily injury and/or
property damage. Retain these instructions for future reference.
This pump has been manufactured with your needs in mind. Properly installed in the right
application, your new A.Y. McDonald pump will give you years of carefree performance.
DANGER Water and electricity can be dangerous if certain precautions are not adhered
to. This pump is designed to operate perfectly safe in a water environment; however, improper
use and installation can result in personal harm from electrical shock. Please pay attention to
the following warnings.
WARNING
Never touch any electrical device, including this pump, when it is touching water, in water, or
even in a moist environment. Always unplug (disconnect the electricity) when working on or
installing the unit.
WARNING
RISK OF ELECTRICAL SHOCK. This pump is supplied with a grounding conductor and
grounding-type attachment plug. To reduce the risk of electrical shock, be certain that it is
connected only to a properly grounded, grounding-type receptacle.
WARNING Do not use the power cord or discharge hose to carry or handle the pump.
Doing so may cause damage to the power cord or discharge hose. Use the carrying handle
supplied with the pump.
WARNING Always use a grounded outlet. A three-prong mating type receptacle is
needed for safe use. This should be in accordance with the National Electric Code and any
additional codes or laws required by your local government.
NOTICE It is strongly recommended to use a ground fault interrupt device on any
electrical appliance, including this pump, when used in a wet or moist environment. This is
required by many local codes and enforcement agencies. It is strongly recommended by A.Y.
McDonald as it provides a much safer installation and will greatly reduce possible injury from
electrical shock.

NOTICE Height and/or piping restriction will reduce the pump output performance. See
the performance chart below to insure you have the proper pump for your application.
Whenever possible use the same size or larger pipe as the pump discharge for optimum
performance. Reducing the pipe size will not harm your pump; it will just reduce the output.

SPECIFICATIONS
Power supply requirements 120V, 60 Hz (15 amp)
Motor Continuous Duty, Capacitor Start,
Thermally Protected
Liquid Temperature Range 32° F - 120° F (0° C - 49° C)
DANGER Do not use this pump to pump chemicals, flammable liquids, sewage or
corrosive liquids. You could injure yourself and the pump will fail. Pumping these types of
liquids voids the warranty.
WARNING
This pump has thermal over-load protection built in. It is not recommended for pumping liquids
over 120°F. The thermal overload protector will automatically shut down the pump in an
overheat situation. It will then reset itself once the pump cools down. This overload is
designed as a safety device and it will fail after repeated use. Normal operation is for fluids
between 32°F & 120°F.
DO NOT RUN THE PUMP DRY. The pump depends on water for cooling and lubrication.
Operating the pump without water may cause the motor to overheat or cause damage to parts
of the pump. It may also shorten the life of your pump.
NOTICE
EXTENSION CORDS
For best performance, it is recommended to connect the power cord directly to the grounded
GFCI outlet. If the use of an extension cord is necessary, always use a grounded waterproof
type cord. Never use longer than a 25-ft. cord that is lighter than 14/3 gauge.
DANGER Keep all electrical connections away from wet and moist environments. Wet
connections can cause electrical shock resulting in personal injury.
USE AND INSTALLATION
WARNING ALWAYS DISCONNECT THE POWER SOURCE BEFORE ATTEMPTING TO INSTALL,
SERVICE OR PERFORM MAINTENANCE ON THE PUMP.FAILURE TO DO SO MAY RESULT IN FATAL
ELECTRICAL SHOCK.
This A.Y. McDonald pump is designed and built to give you reliable performance and long life.
It will pump water automatically for years when properly installed in the right environment.
REMOVING OLD PUMP (If necessary)
1. Make sure power supply is disconnected.
2. After the power is off, remove the old pump. There are many different possible types
of installations.
3. It is best to remove all old piping and start over with new piping. Be sure to clean all
debris and dirt out of the sump basin before installing your new pump.
Be sure to have a grounded 120V AC outlet mounted within 6 ft. of your sump basin. Again, it
is highly recommended that a GFCI (ground fault circuit interrupter) outlet be installed in the
receptacle box.
NOTICE A qualified electrician must perform all wiring.

INSTALLATION (New Pump)
1. Set your new pump in the bottom of the sump basin off to one side. The pump should be
placed on a solid foundation. Do not place the pump directly on the ground or on sandy
or rocky surfaces. Sand and small stones may clog or cause damage to your pump.
2. Make sure the float switch will swing freely from the bottom to top without coming in
contact with the side of the sump basin. Contact with the side of the sump basin may
cause the switch to malfunction. See figure below.
3. It is highly recommended to install a full flow, swing type check valve (not included)
as close to the discharge outlet on the pump as possible. A new check valve will
greatly increase the life of your pump. The check valve should be the same size as
the pump discharge.
4. Connect the pump and check valve together using schedule 40 PVC pipe and
fittings. You can also use DWV or ABS pipe, as this is not a pressure installation.
Corrugated drain hose is intended for temporary use and should not be used in a
permanent installation. Although there are many types of pipe that work adequately
for this installation, PVC is recommended.
5. Test your installation after you have completed setting up the pump. Plug the cord
from the pump into the piggyback plug of the float switch, then plug that into your
grounded outlet. The pump should not run at this point. If the pump runs, the switch
is stuck in the upright position or the pump is plugged directly into the outlet and not
through the piggyback switch plug. Fill the sump basin with water using buckets or a
hose. When the switch floats to the upright position, the pump will turn on. The
switch will turn off the pump when it reaches the down position. You may adjust the
switch to meet your particular needs. Remember the switch must swing freely
without touching the sides of the sump basin. NOTE: The cut out (turn off) setting is
the only adjustment available on vertical type switches.
