English (US)
Incoming water pressures fluctuate in nearly
ALL water systems because of demand/usage.
Therefore, pressure monitoring may be required
for a day or more to determine your maximum
incoming water pressure. If the incoming water
pressure is confirmed to be greater than 40 PSI,
a pressure regulating valve MUST be installed on
the water supply piping feeding the pump.
You are advised to check water source pressure
before installation. To determine the highest
pressure at the water inlet over 24 hours of
testing, a lazy hand gauge is recommended.
The MAXIMUM inlet pressure for the Watts MQ
3-45 is 40 PSI. Running the pump with a inlet
pressure higher than 40 psi may cause the pump
to leak. Watts will not be responsible for any
damage to the pump and/or its surroundings if
this warning is not followed.
3. Introduction
The MQ is a low-noise water supply system
consisting of pump, motor, pressure tank and controller
combined into one compact unit.
The system is suitable for both indoor and
outdoor use. Cover required for outdoor installation.
Watts Part MQ 3-45 COV 96693071 (Grundfos
#96693071)
The self-priming pump starts automatically when
water is consumed in the installation and stops when
consumption ceases. The internal, built-in non-return
valve prevents backow during priming and
operation.
The MQ pump incorporates overtemperature
and dry-running protection as well as a user-friendly
control panel.
The built-in pressure tank reduces the number of
starts and stops in case of leakage in the installation.
5. Applications
The MQ water supply system is designed for these
typical applications:
• water pressure boosting
(maximum inlet pressure: 40 psi)
• water supply from wells
(maximum suction lift: 25 ft), for example
– in private homes
– on farms
– in market gardens and other large gardens.
The pump is suitable for rain water.

For outdoor installation, the pump
must be fitted with a protective cover
(accessory). See section 8.5 Protective
cover and 14. Accessories.
Should the unlikely event of an internal
leakage occur, pumped liquid will be
drained out from the base and/or end
cover instead of damaging the pump.
To prevent potential damage, select an
installation location that would not be
adversely affected by water.
The pump must be installed horizontally.
The maximum permissible inclination angle is ± 18 °.
See g. 2.
To prevent movement and vibrations, the pump and
base plate can be secured to a solid foundation by
means of the bolt holes in the base plate.
For pipework connection, see section 8.4 Pipework.
The bolt holes are covered by a thin plastic layer that
must be knocked out before use. See g. 3.

8.4.2 Suction hose instead of pipe
If a suction hose is used instead of a pipe, the hose
should not exceed the lengths stated in the graph
located on page 57. The suction hose must be
a minimum of 1" in diameter and be of the non-
collapsible type.
8.4.3 Long suction pipes
A separate non-return inlet valve is supplied with the
pump. In case of long suction pipes, we recommend
that you t the non-return inlet valve in the pump
suction port. See section 8.4.4 Fitting of the non-return
inlet valve
The pipes must be adequately supported on either
side of the pump to avoid straining the pump
connections.
8.4.4 Fitting of the non-return inlet valve
The non-return inlet valve reduces the risk of losing
pump priming in negative suction applications and
improves the auto-aspiration capability, for example
in water supply from a cistern.
Install the non-return inlet valve as follows, see
g. 10:
1. Remove the suction connection of the pump.
2. Fit the non-return inlet valve into the suction port
in the direction shown in g. 10.
3. Ret the pump connection.
Applications with positive inlet pressure do not
require installation of the non-return inlet valve
due to the fact that the MQ pump incorporates an
internal non-return valve at the discharge side.
8.5 Protective cover
Failure to use the protective cover in outdoor
installations will invalidate the warranty.
The protective cover is available as an accessory.
See section 13. Accessories.
To t the protective cover, click the cover onto the
top of the control panel so that it engages with the
top cooling ribs.
To remove the cover, pull the two clips outwards, free
of the cooling ribs, and pull the cover upwards.

9.4 Startup
Before start-up, the pump must be lled with 1.2 to
1.5 gallons of water to enable it to self-prime,
see g. 15. The pump is self-priming with a
maximum suction lift of 25 ft.
Fig. 15 Priming the pump
When started, the pump begins to self-prime.
When it has been primed, the pump will
automatically change over to normal operation.
If the priming has not been completed within
5 minutes, the pump will stop automatically and
attempt to restart after 30 minutes. It is possible to
reset the pump manually, see point 2 in the table of
section 10.1 Control panel.
Running the pump at a higher inlet
pressure than recommended (40 psi)
can cause the pump to leak.
Watts will not be held responsible for
any damage to the pump and/or its
surroundings if this warning is not
followed.

11. Maintenance
Under normal operating conditions, the pump is
maintenance-free. However, it is recommended to
keep the pump clean.
Do not remove the pressure tank from
the pump unless it has been vented
through the air escape valve.
Never touch the electronics unless the
pump has been switched off for at least
5 minutes.
If there is any risk of frost damage, drain the pump
through the drain hole and slacken the union nut on
the discharge pipe, see g. 17. The pump must be
lled with liquid before it is started up again.
See g. 15.

Fig. 17 Draining the pump
11.1 Shaft seal run-in
The seal faces are lubricated by the pumped liquid,
meaning that there may be a certain amount of
leakage from the shaft seal.
When the pump is started up for the rst time, or
when a new shaft seal is installed, a certain run-in
period is required before the leakage is reduced to
an acceptable level. The time required for this
depends on the operating conditions, i.e. every time
the operating conditions change, a new run-in period
will be started.
Under normal conditions, the leaking liquid will
evaporate, which means that no leakage will be
detected.
11.2 Start-up after a long period of
inactivity
The end cover incorporates a plug which can be
removed by means of a suitable tool. See g. 18.
It is then possible to free the pump rotor if it has
seized up as a result of inactivity. If it has been
drained, the pump must be lled with liquid before
start-up. See g. 15.

15. MQ frequently asked questions
1. What causes the MQ to start?
Answer: The MQ is equipped with both an
internal ow switch and pressure switch. Each of
these can turn the MQ on, depending on water
consumption. The pump will start when: The ow
rate is greater than 0.3 gpm
OR
the pressure is below 29 psi.
2. What causes the MQ to stop?
Answer: Other than the manual on/off button,
only the ow switch is authorized to automatically
stop the MQ during normal operation when ow
drops below 0.3 gpm. The pump will shut off in
12-15 seconds after ow stops.
Additionally, the MQ will be turned off in the event
of a dry-run or overtemperature alarm.
3. What is the maximum height of a tap above
the MQ?
Answer: If a tap or faucet is installed at heights
greater than 50 ft above the MQ, there is the
potential risk that the MQ will never start.
In cases where the MQ starts due to low pressure
(low ow rates), the pressure has to fall below
the pressure switch activation point (28-30 psi
factory setting). To allow for the pressure of 50 ft
of water, tolerances and a safety margin, we
recommend a maximum height of 50 ft between
the MQ and any tap.
4. What is the purpose of the built-in pressure
tank?
Answer: The built-in pressure tank comes from
the factory, pressurized at approximately 23 psi
(with the pump pressure at zero) and holds a
volume of 14 ounces of water. It is designed to
minimize motor startup due to small leaks.
5. How is the dry-run condition determined?
Answer: The dry-run alarm is declared when the
motor is running AND the ow rate is less than
1.6 gpm AND when pressure is less than the
pressure switch setting. When this condition lasts
for 12 seconds, the alarm will be declared after
1 minute, and the motor is stopped. The MQ
attempts to automatically restart every
30 minutes for a maximum of 24 hours. If more
than 24 hours pass without water, the pump must
be restarted manually.
6. What is the maximum inlet pressure allowed
in the MQ?
Answer: For MQ 3-45, the maximum internal
pressure allowed is 109 psi. The maximum inlet
pressure when added to the MQ pressure must not
exceed 109 psi. Remember that inlet pressure adds
to the MQ pressure, so with a 40 psi inlet pressure
supplied to the MQ 3-45, internal pressures can
reach approximately 103 psi (63 + 40 psi).
Additionally, if inlet pressures exceed the built-in
pressure switch activation point (28-30 psi factory
setting), the pressure switch will be unable to
activate, and the ability to turn the MQ on at low
ow rates will be lost. In this situation, only the ow
switch will be able to turn the MQ on at ow rates
above its activation point of 0.3 gpm.
7. What is the priming capacity of the MQ?
Answer: Approx. 1.2 gallons.
8. How is overload temperature/overtemperature
of the MQ detected?
Answer: The motor has a thermal switch
incorporated in the motor windings.
The switch will cut out the motor and start again.
See the table below.
