RISK OF ELECTRICAL SHOCK. Do not plug in or unplug the AC transformer while standing
on a wet floor. If basement floor is wet, disconnect the power before walking on the floor.
Battery acid is corrosive. Do not spill on skin, clothing, or parts of this system. Wear
gloves and eye protection when handling the battery.
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.
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.
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.
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.
Keep all electrical connections away from wet and moist environments. Wet connections
can cause electrical shock resulting in personal injury.
Do not use this unit 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. A.Y. McDonald and other pump companies manufacture pumps for these types
of liquids. Make sure you purchase a pump designed for your specific needs. This pump
will handle fluids with the same characteristics as water.
RISK OF ELECTRICAL SHOCK. 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.
Important Safety Information:
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.

EXTENSION CORDS: For best performance, it is recommended to connect the AC
transformer power cord directly to a grounded GFCI outlet. The use of extension cords is
NOT recommended.
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.
Always use a grounded outlet to attach the plug. 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.
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 GFCI
(ground fault circuit interrupter) should be listed by Underwriters Laboratories (UL). 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.
Your 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. The pump will
then work again. 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 PUMPS DRY. The pumps depends on water for cooling and lubrication.
Operating the pumps without water may cause the motor to overheat or cause damage to
parts of the pump. It may also shorten the life of your pumps.
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.
A qualified electrician must perform all wiring.

BATTERY SELECTION
This system is designed to work with 12 volt, lead-acid deep cycle marine / RV batteries.
Either a flooded cell (serviceable or maintenance free) or sealed AGM battery are acceptable.
Choose a battery with a minimum 90 amp-hour rating and a 175 minute reserve capacity or
larger. Avoid using automobile batteries as these types of batteries are not intended to be
charged/discharged for extended periods of time. The battery case will accommodate size
24 or 27 batteries.
During prolonged periods of power failure or in an emergency, your automobile battery may
be used. Make sure to replace the deep cycle battery as soon as possible as the automobile
battery will be quickly ruined by the continuous charge/discharge cycles.
GENERAL INFORMATION
This battery back-up system is not intended to replace your primary sump pump. It is
intended to provide temporary back-up during power failures or malfunctions with the
primary pump.
CARBON MONOXIDE (CO) DETECTORS
All back-up pump systems that use lead acid batteries, regardless of brand, give off gaseous
by-products when the battery is charging. Some of these by-products can cause a carbon
monoxide (CO) detector to give a false alarm. When installing this system, position the
battery as far away from the CO detector as possible. DO NOT move or remove CO
detectors from their original location. Always follow the instructions that accompany your
CO detector.
If your CO detector alarm sounds, take the following actions.
1. Take immediate action for personal safety as outlined in the CO detector manual.
2. Contact the appropriate utility agency to determine if the CO is coming from your
furnace, water heater or other appliance that uses natural gas
If it’s determined that a charging battery is causing the CO detector to activate, contact the
manufacturer for recommendations on how to alleviate the problem.
INSTALLATION
A qualified electrician must perform all wiring.
RISK OF ELECTRICAL SHOCK. 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 pump kit is completely assembled. To install,
simply place the pump assembly in the bottom of your
basin and connect to your new or existing discharge
pipe. The pump should be placed on a solid foundation.
Do not place the pump directly on the ground or sandy
or rocky surfaces. Sand and small stones may clog or
cause damage to your pump. Make sure the float
switches will operate freely without coming in contact
with the sides of the sump basin. Contact with the side
of the sump basin may cause the switch to
malfunction. See figure.

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.

WIRING & ELECTRICAL CONNECTIONS
1. If necessary, attach the provided battery terminals to the battery. (Many
deep cycle marine batteries come with a threaded post terminal built in.)
NOTE: The provided battery terminals are labeled (+) positive and (-)
negative. Make sure the terminals are connected to the proper terminal on
the battery. Place the battery in the battery box.
2. Connect the battery lead wires from the control panel to the corresponding
terminals on the battery. Connect the red (+) positive lead to the positive
battery terminal and tighten the wing nut. Connect the black (-) negative
lead to the negative battery terminal and tighten the wing nut. Secure the
battery box cover to the lower case.
3. Next connect the pump power cord, the float switch and the AC adapter to
the corresponding terminals on the control panel. Make sure they are fully
seated in the terminals.
4. Plug the AC adapter into the wall outlet and turn the power back on.
5. If your battery is fully charged you will notice a green light on the AC
adapter. If the battery is not fully charged a red light will indicate that the
battery is charging. Once fully charged, the light will change to green.
6. Once all connections are made, press the “MUTE/ALARM” button on the
control panel until the “ALARM” light illuminates. This indicates that the
alarm will sound once the pump is activated. To mute the alarm, press the
“MUTE/ALARM” button on the control panel until the “ALARM” light turns
off.
7. Test the float switch and pump by lifting and holding the float. The alarm
will sound and the “PUMP ON” light on the control panel will illuminate. The
pump should start after lifting the float. If it does not run, check your
connections and retry.

TESTING YOUR INSTALLATION
1. Once your installation and wiring connections are complete, unplug or
disconnect the power to the primary pump.
2. Fill the basin using buckets or a hose. Observe the float switches to make sure
they are positioned properly when the basin is filling. Fill the basin until the
back-up float activates the alarm.
3. Make any necessary adjustments to the float(s) and/or pumps at this time.
OPERATION
1. When the power fails or when there is a problem with the primary pump, the
back-up pump will automatically start. The back-up pump will operate for many
hours intermittently. During prolonged periods of power outage the pump may
stop pumping when the battery voltage drops below 10 volts. When this
happens the alarm will sound signaling that the voltage is too low to operate the
pump.
2. This unit is equipped with a 2 amp charger. It will charge a discharged battery at
a rate of 2 Ah (Amp hours). Once the battery reaches a full charge, the charger
will gradually reduce the charge rate. It will also maintain a charged battery by
periodically checking the voltage of the battery.
3. The charger is equipped with over charge protection. It will not let the battery
become over charged.
