General Safety
1. To avoid risk of serious bodily injury and property
damage, read the safety instructions carefully before
installing this pump.
2. Follow local and/or national plumbing, building and
electrical codes when installing the pump. Use rigid
pipe when installing this pump.
Hazardous pressure. The pump body may
explode if used to boost pressure above 100 psi
(689 kPa). Do not use this pump with inlet pressure
greater than 50 psi (345 kPa). If not already in the
plumbing system, install a pressure relief valve in
the pump discharge line capable of passing the
full pump flow at 100 psi (689 kPa). If local code
requires installation of a pressure relief valve capable
of handling the full pump flow at a pressure less than
100 psi (689 kPa), follow the code requirements.
4. A low pressure safety cutoff switch is recommended
to shut off power to the pump in case of low
discharge pressure due to interruption of the
incoming water supply, broken pipe, etc.
5. Never run the pump dry. To do so can damage
internal parts, overheat pump (which can cause
burns to people handling or servicing pump), and
will void warranty.
Risk of fire or explosion. To avoid risk
of fire and explosion, Pump Water Only with this
pump. Do not pump flammable liquids or chemicals.
Do not use the pump near gas pilot lights or where
chemical or gas fumes are present. Use of an
electric pump with liquids other than water or in
an atmosphere containing chemical or gas fumes
may ignite those liquids or gases and cause injury or
death due to an explosion and/or fire.
Risk of burns. If water is trapped in the
pump during operation it may turn to steam. Trapped
steam can lead to an explosion and burns. Never run
the pump with the outlet closed or obstructed.
Risk of burns. Do not touch an operating
motor. Modern motors can operate at high
temperatures. To avoid burns when servicing the
pump, allow it to cool for 20 minutes after shutdown before handling.
Electrical Safety
The pump is supplied with a 3-conductor grounding
type cord. Connect only to a properly grounded,
GFCI protected outlet. Do not lift the pump by the
electrical cord.
Hazardous voltage. Can shock, burn or cause
death. Ground the pump before connecting to a power
supply. Disconnect the power before working on the
pump, motor or tank.
• The pump and controller are non-submersible.
Keep the motor dry at all times. Do not wash the
motor. Do not immerse. Protect the motor from
wet weather.
• If using an extension cord, use only an approved
indoor/outdoor, 3-wire, 14GA, grounding type cord.
Do not allow any part of the cord or the receptacle
ends to sit in water or in damp locations.
• Unplug the pump before servicing. To avoid
fatal shock, proceed as follows if the pump
needs servicing.
• Disconnect the power to the pump outlet box before
unplugging the pump. After the plug is pulled, let the
pump cool for 20 minutes before attempting to work
on it.
• Take extreme care when changing fuses. To reduce
the chance of fatal electrical shock, DO NOT stand
in water or put your finger in the fuse socket.
• Ground the electrical outlet box.
• Plug the pump and the controller into a Ground
Fault Circuit Interrupter (GFCI) protected grounded
outlet only.

General Information • Installation
Use the Ace-In-The-Hole Automatic Booster Pump to
boost city water pressure. Plumbing connections are
described in this manual.
General Information
• Pump only clean water with your Ace-In-The-Hole
Automatic Booster Pump. To avoid clogging the
pump and damaging the shaft seal, do not pump
water containing solids, foreign material, sand, silt,
or abrasives.
• If you are boosting the pressure from a well pump,
be sure that the system check valves are tight. If the
system pressure drops when the well pump is not
running, the Automatic Booster Pump may start and
cycle. Excessive or rapid cycling may damage the
motor and will void the warranty.
• Do not use pipe joint compound on pump ports;
use only PTFE tape to seal the threads. Pipe joint
compound will damage the controller materials.
NOTICE: The priming plug has an O-ring already
installed and does not require sealing.
• Tighten all the piping joints to the pump hand tight
plus 1-1/2 turns (not more).
Overtightening may break the pump and will void
the warranty.
• Pipe and fittings to the pump should be at least
nominal 1” diameter. Pipe or fittings less than 1” in
diameter will reduce performance and may damage
the pump through cavitation.
• Make sure that there are no air leaks or air pockets
in the suction pipe. An air leak in the suction pipe
may draw air in, although no water leaks out. Air
leaks and air pockets will prevent the pump from
priming properly, and can substantially reduce
its performance.
• The pump mount should be level, solid, as near as
possible to the water source, and protected against
excess moisture and flooding.
• Use the shortest possible run for piping and the
smallest possible number of fittings. Long pipe runs
and numerous fittings increase friction and reduce
the flow of water.
• Support the weight of the piping and pump.
• Do not allow the pump, pressure controller, or any
system components to freeze. Freezing will damage
the pump and void the warranty.
• Periodically inspect the pump, pressure controller,
and system components.
NOTICE: Local code may require a pressure relief valve
or pressure regulator.
Risk of leaks and flooding. Do not use this
pump with inlet pressure less than 10 psi (70 kPa) or
greater than 50 psi (345 kPa).
Figure 1 – Do Not Run the Pump With Inlet Shut Off
Pressure hazard and risk of explosion. This
pump can develop high pressure when operated with the
discharge shut off or obstructed. For safe operation, we
recommend the following:
If not already in the plumbing system, install a pressure
relief valve in the pump discharge line capable of passing
the full pump flow at 100 psi (689 kPa). If local code
requires installation of a pressure relief valve capable
of handling the full pump flow at a pressure less than
100 psi (689 kPa), follow the code requirements. Run the
relief valve discharge to a floor drain or other drain that
will give adequate runoff.
Risk of flooding. Be sure that all plumbing and
fittings are rated to withstand the system pressure which
you expect the pump to generate.
1. Decide what’s the best place to install the pump.
Think about these things:
• it must be near the main water supply line
• the pump must be accessible
• the power cord must reach a power outlet
• the controller’s LED lights must be visible
• ease of plumbing
• space saving
NOTICE: Installation of a low pressure safety cutoff
switch on the pump discharge is recommended (and
may be required by your local code) to shut off the
power in case of low discharge pressure (caused by
broken pipe, etc.).
2. Mount the pump on a solid base in the location you
have decided on.
3. Choose a time that will allow you to shut off
the water to the household while you install the
Automatic Booster Pump.
4. Shutoff the main water supply valve to the household.
5. Open any faucet to relieve water pressure in the
plumbing. Once the water pressure is relieved, close
the faucet.
For parts or assistance, call Simer Customer Service at 1-800-468-7867
You must remove a length of pipe from the main
water supply line to allow installation of elbows
for the Automatic Booster Pump. The locations of
the cuts must take into consideration the size of
the elbows being used, the length of the threads in
threaded joints or the overlap in glued or soldered
joints, etc.. Position the elbows in line with the
pump suction and discharge threads. There may be
some water leakage while cutting the pipe. Remove
any burrs or shavings caused by the cutting tool.
NOTICE: Galvanized pipe may not need to be cut.
If there is a union close to the pump location, dis­
assemble the union and remove (unscrew) pipe back
past the pump location. Have new lengths of pipe
cut and threaded to allow for the pump installation.
NOTICE: Both female suction and male discharge
ports have 1” NPT threads. Depending on your type
of connection and the size of your home’s piping,
you may need to install adapters on the ports.
7. Once the short piece of pipe is removed, the piping
above the cut can be drained to prevent water
mess. Place a pail under the opening going to the
household. Open the highest faucet in the system to
let in air so the water can fall out of the pipes into
the pail. Once it’s drained, close the faucet.
8. Install the elbows in the main water supply line.
Point them toward the pump.
Risk of burst hose and flooding. Do not
install with flexible hoses. Use only rigid piping that
meets code.
9. Install piping from elbows to pump including a
union in each line, an elbow in the discharge line,
and a check valve in the pump suction line. The
arrow on the check valve must point to the pump
suction (see Figure 2). If not already in the plumbing
system, install a pressure relief valve in the pump
discharge line capable of passing the full pump
flow at 100 psi (689 kPa). If local code requires
installation of a pressure relief valve capable of
handling the full pump flow at a pressure less than
100 psi (689 kPa), follow the code requirements.
A low pressure safety cutoff switch should also be
installed in the discharge line, and may be required
by your local codes.
10. With all pipe and fittings installed and sealed, turn
on the main water supply slowly to pressurize the
system and check for leaks. If any leaks appear,
turn the main valve off, open a faucet to relieve the
pressure, and repair the leak. Repeat this step until
there are no leaks in the system.
11. Open a faucet to release the air from the pipes and
allow water to flow. When a steady stream of water
flows out of the faucet, the pump is full of water and
fully primed. Close the faucet.

12. Before continuing with the installation, see the
manual sections titled Electrical Connections,
Automatic Pressure Controller, Normal Operation,
and When Does The Pump Stop Operating for
detailed information on how the system functions.
13. At this point, you can plug in the pump for the first
time. When you plug in the power cord, the pump
will start and run for a few seconds.
14. When the pump stops running (after it shuts off
automatically), the system is at the boosted pressures.
Inspect the pipe and fittings again for water leaks. If
any leaks appear, unplug the pump, turn the water
main valve off, open a faucet to relieve the pressure
and repair the leak. Repeat this step until there are
no leaks in the system.

Installation • Operation
Electrical Connection
Hazardous voltage. Risk of dangerous or
fatal electric shock. Plug the pump into a 115 Volt,
60 Cycle, Ground Fault Circuit Interrupter (GFCI)
protected grounded outlet only. The pump is equipped
with a 3-wire grounded cord and plug. Do not modify
or remove the plug. Make sure the outlet meets the
National Electric Code or the Canadian Electrical Code,
as applicable. To avoid dangerous electrical shock
hazard, keep the cord dry at all times. See Figure 2.
Automatic Pressure Controller
The Automatic Pressure Controller mounts on the pump.
It protects against:
• Run-dry operation;
• Frequent starts caused by small water losses in
the system;
• Pressure drop.
The Automatic Pressure Controller features the following
LEDs and controls:
- ‘Power on’ LED: indicates that the unit is electrically
connected and that voltage is present. The pump is
ready to operate.
- ‘Pump on’ LED: indicates that the pump is running
and actually pumping water.
- ‘Failure’ LED: indicates that no water is detected
coming into the pump.
- ‘Restart’ button: resets any safeties which have
tripped and allows the pump to restart.

Normal Operation Of The Automatic
Booster Pump
Risk of burns. NEVER run the pump dry.
Running the pump without water may cause pump to
overheat and cause burns to persons handling the pump.
It may also damage the impeller and may damage the
seal, causing leaking or flooding, and will void the
warranty. Fill the pump with water before starting it.
Make sure that the Automatic Booster Pump has been
properly installed and primed, and that the suction pipe
is unobstructed and open.
Plug in the pump. The ‘Power on’ and ‘Pump on’ lights
will come on indicating, respectively, that voltage is
present and that the pump is ready to operate.
The pump will start and will continue to operate until
several seconds after the system pressure has risen and
flow has stopped.
When Does The Pump Stop Operating?
Pressure Set-Point/No Flow: The pump will stop
operating and the ‘Pump on’ LED will go off several
seconds after:
• The system pressure is above the starting pressure,
• The flow has stopped.
This is normal operation.
Restart: A water flow in the system greater than 1/4 GPM
or a drop in pressure below the starting pressure set-point
will cause the pump to restart and the ‘Pump on’ LED to
light up. The pump will continue to operate until several
seconds after:
• It reaches the maximum pressure of the pump, and
• The flow stops.
NOTICE: The delay in shutting off the pump prevents
rapid cycling when water faucets are being turned
on and off quickly (for example, when brushing
teeth, etc.).
Pressure Drop/No Flow: Normally, when the pump
starts, it will very quickly generate pressure and sense
flow. If there is no flow and the pressure does not rise,
it senses a “no water” condition. It can also sense this
during operation if the water supply to the pump fails. To
protect the pump from running dry:
• Several seconds after it detects “no water”, the pump
will stop operating,
• The ‘Pump on’ LED will go out, and
• The ‘Failure’ LED will go on.
For parts or assistance, call Simer Customer Service at 1-800-468-7867
Operation • Service • Troubleshooting
Restart: Make sure that the suction line is not obstructed,
and that it is connected to a water source.
• Press and hold the ‘Restart’ button for 5 seconds.
• The ‘Pump on’ LED should light up, and
• The ‘Failure’ LED should go off.
If flow is adequate, the pump will operate until
several seconds after it reaches the set-point pressure
and the flow stops.
The motor is lubricated at the factory for the life of
the bearings. The pump seal is water cooled and
self lubricating.
Pump Service
Hazardous voltage. Can shock, burn, or cause
death. Unplug the pump and controller before servicing
them. Do not handle the pump or controller or attempt
to work on the pump with wet hands or while standing
on a wet or damp floor.
The motor has an auto-reset thermal overload protector.
If the motor overheats, the overload will cut off the
power to prevent damage and will reset after the motor
cools. If the overload trips repeatedly, check the pump
for the cause (low voltage, a clogged impeller, etc.).
