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.
