1. INSTALLATION OF THE DAVEY VARIABLE SPEED PUMP
The SilensorPRO should be located as close to the water as practicable and mounted on a firm base in a
well drained position, high enough to prevent any flooding. It is the installer/owner’s responsibility to locate
the pump such that the nameplate can be easily read and the SilensorPRO can be readily accessed for
service. It is recommended that the SilensorPRO is protected from the weather. Enclosures should be
ventilated to prevent condensation build-up.
Failure to follow these instructions and comply with all applicable codes may cause
serious bodily injury and/or property damage.
This pump requires professional expertise for installation and maintenance. The
installation of this product should be carried out by a person knowledgeable in
swimming pool plumbing requirements and who follows the installation instructions
provided in this manual.
Power connection
IMPORTANT INFORMATION Your SilensorPRO is double insulated to water circuit.
If equipotential bonding structure is required, then an Equipotential Bonding Point
is provided. (Please refer to your local statutes and/or regulations for AS/NZ 3000
equivalent wiring standards).
CAUTION! In the interest of safety, we advise that all brands and types of pool pumps
must be installed in accordance with AS/NZS 3000, known as the national wiring
rules, or equivalent local standards. All electrical installations must be carried out by
a qualied electrician. Davey recommends that all installations are tted with earth
leakage, or residual current protection devices. Rated residual operating current not
exceeding 30mA.
WARNING! Ensure that an electrical isolation switch is located with easy access so that
the pump can be switched off in an emergency.

The SilensorPRO is suitable for connection to a nominal 220 – 240 volt 50/60Hz power supply and is
equipped with a flex cord. If a power outlet is not available within 3 metres of the pump, a 3-pin power point
in a safe, dry place may need to be provided by an electrician. Extension cords are unsafe around pools and
should be avoided. If the supply cord of the SilensorPRO is damaged it must be replaced by Davey, or an
approved agent with genuine Davey spares.
The SilensorPRO incorporates motor overload detection designed to protect the motor from overheating.
If the motor gets too hot during operation, its operating speed will reduce to bring it within an acceptable
operating temperature and then will speed up to the originally set speed.
To reset the motor, switch the power off for 30 seconds, and then return the power from the mains switch.

Pipe connection
Barrel unions are provided for connecting to the piping from the pool. The pumps are designed to accept
50/63mm PVC fittings.
IMPORTANT INFORMATION If the SilensorPRO and lter are located below pool water
level, it is necessary to t isolating valves in the pipe between the pump and skimmer
box and in return pipe from the lter to the pool. When plumbing the discharge pipe,
ensure that the pipework does not interfere with the pumps speed dial. Barrel unions
need to be hand tightened. No sealant, glues or silicones are required.
The ttings on the SilensorPRO are constructed of ABS. Some PVC jointing compounds
are incompatible with ABS. Check compound suitability before use.
The use of any pipe smaller than those specified above is not recommended. Suction piping should be free
from all air leaks and any humps and hollows which cause suction difficulties. To achieve best efficiency, the
SilensorPRO should be installed such that turbulent water is limited as much as possible. As shown in figure
1.1, do not install a 90° elbow closer that 250mm from the inlet barrel union. Isolation valves used where
equipment is located below pool water level, should also be installed no closer than 250mm from inlet barrel
union. This will assist laminar flow.

The discharge piping from the SilensorPRO outlet should be connected to the inlet connection on the
swimming pool filter (usually at the filter control valve). As shown in figure 1.2, ensure adequate clearance
above the pump to not interfere with the SilensorPRO speed dial. Use a check valve in the discharge line
when using this pump for any application where there is significant height to the plumbing after the pump.

Be sure to install check valves when plumbing with another pump. This helps prevent reverse rotation of the
impeller and motor.
WARNING! Pump suction is hazardous and can trap and drown, or disembowel bathers.
Do not block suction. Do not operate swimming pools, spas, or spa baths if a suction
cover is broken, missing or loose. Two suction covers, or inlets must be provided into
every pump to avoid suction entrapment.

4. OWNERS MANUAL
This SilensorPRO is Bluetooth enabled, so you will be able to set and control the pump functions from your
smart device. Bluetooth is a wireless communication protocol that enables communication between devices.
This function is supported by any device that can download an app from IOS or Android App Store.
Read these instructions in their entirety before switching on this pump. If you are uncertain as to any of these
installation and operating instructions, please contact Davey as listed on the back of this document.
Every SilensorPRO is thoroughly water tested against a number of flow, pressure, voltage, current and
mechanical performance parameters. Davey’s advanced pump manufacturing technology provides reliable
and efficient pumping performance that lasts and lasts.
Saving energy with your SilensorPRO
The Davey variable speed pump is a super-efficient pump utilising a very clever, state of the art infinitely
variable AC motor that provides lower levels of noise, lower operating costs and lower greenhouse emissions
than traditional pool pumps.
Due to its ability to run at lower speeds than conventional pumps, your pump will also experience less
mechanical wear and tear due to less stress on the internal mechanical components. To achieve energy
efficient pumping is easy. Simply run the filtration pump at a lower speed but run it for longer than a
conventional fixed speed pump to “turn over” your pool water for adequate filtration and sanitisation. The
result is lower energy use and up to 70% lower operational costs.
The SilensorPRO has adjustable speed settings, so you can vary the speed you circulate your pool or spa
water at. Speeds can be adjusted to power a suction pool cleaner, in-floor cleaning system & pool heaters. A
backwash setting on the pump can be selected to backwash a media filter.
What to expect with the SilensorPRO (energy efficient operation) on your pool:
• If your SilensorPRO pump is replacing a traditional AC motor pump, you may will need to run it longer than
your old fixed speed pump. This is NORMAL and you will save energy when using lower speed settings.
• You may also notice that the pressure gauge on your filter is indicating a much lower pressure than you are
used to. This is also NORMAL. The lower system pressure is simply a result of the lower speed and flow
rate produced by the pump.
• While running at the lower speed settings you will also notice a significant reduction in pump noise. This is
a major benefit for you as it allows you to run your SilensorPRO during off peak electricity tariffs, which will
also assist in the reduction of your operating costs. Plus, you will also have much happier neighbours.
Many pool products rely on minimum flow rates for best operation and/or efficiency. If you are using low flow
settings on the SilensorPRO (e.g. speed 1 to 4) Davey recommends that you check the compatibility of the
speed or minimum flow rate required to run specific pool equipment such as:
• Suction pool cleaners;
• Ozone generators;
• Heating systems;
• Salt water chlorinator cells;
• In-floor pool cleaning systems.
Pre-start up checklist
• Speed setting chosen is a compatible setting with other pool equipment;
• The pump is installed in a safe and dry environment;
• The pump enclosure has adequate drainage in the event of leakage;
• Any transport plugs are removed;
• The pipe-work is correctly sealed and supported;
• The pump is primed correctly;
• The power supply is correctly connected;
• All steps have been taken for safe operation;
• The filter has been plumbed with 50/63mm pipe;
• The (app) schedule settings correspond with any other times in the system.
English

Low energy operation
Your SilensorPRO SP200BT has speed settings from 1,500 - 3,600rpm. The SilensorPRO SP400BT has
speed settings from 1,050 - 3,100rpm. Speed 1 being the slowest and speed 10 being the fastest.
• Speed 1 provides the lowest speed and therefore the greatest energy efficiency and savings.

Failure to undertake regular maintenance may cause damage not covered by warranty.
Routine maintenance
To maximise the life of the SilensorPRO, and for personal safety use this checklist once a week. Ensure
pump is off before starting:
• Make sure that any pressure gauges are in working condition and the operating pressure is within limits as
specified on the product;
• Make sure that each suction inlet and main drain has a cover that is securely attached and in safe working
condition;
• Make sure that all skimmer covers are securely attached and in safe working condition. These should be
replaced every 3 to 4 years;
• Remove any obstructions or debris from the main drain cover;
• Ensure the skimmer and pump baskets are free of leaves and debris at least once a week;
• Remove obstructions and combustibles from around the pump motor;
• Make sure all wiring connections are clean and that all wiring and electrical equipment is in good condition.

5. FEATURES & FUNCTIONALITY
The SilensorPRO has several operational features. The following explain each of these.
Multi-coloured LED indicator light
Used for identifying required settings for programming time for full speed (Boost) cycling and warnings:
• Solid green = Normal dial operation
• Slow flashing green = In backwash mode
• Fast Flashing green = AUX external control
• Solid White = Time to Backwash
• Fast Flashing White = Fault detected - reset pump
• Slow Flashing blue = Operated by Bluetooth
• Solid blue = Bluetooth mode
Backwash speed cycling technology
When in backwash mode the SilensorPRO will cycle between a low and high speed to help agitate the filter
media for a more effective clean. This reduces wasted water and chemicals during the backwash cycling
process.
Full variable frequency drive with user friendly selectable speed dial
• Provides for easy selection of desired filtration speed
• No complicated digital push button controls
Large 4.5 litre lint pot
• Provides for longer intervals between cleaning
Patented water-cooled design for smooth and super quiet operation
The SilensorPRO has a water-cooled membrane and jacket around the motor which helps to keep the pump
cool during operation. Waste heat off the motor is transferred into the pool water, helping to reduce pool
heating energy costs.
SP400BT constant flow/speed compensation
As the pool filter becomes dirty, pressure builds up. With a typical pool pump, this would naturally slow the
flow coming through the system. The SilensorPRO has the intelligence to automatically detect the resistance
applied by a filter and slowly compensate the reduction flow, by increasing the speed of the motor. The result
is the flow remains constant between filter cleans.
When the SilensorPRO detects that the speed increase indicates time to backwash your filter, the LED
indicator will show a solid white display (see item above).
SP400BT weatherproof RJ45 communication port
(see section 7 for connection details)
• For communication and connecting to external pool control systems
• For receiving a signal from a heat pump, or gas heater to ramp the SilensorPRO speed to full during the
heating process
• Service diagnostics and software updates (For Davey use only)

Check that the cable you use has the above colour coding pins 1 through to 8. If an alternative colour coding
has been used make sure to record the colour which corresponds to each pin to avoid misconnection at
the pool controller or heater. If an alternative cable is used make sure the analogue input and ground are a
twisted pair.
The 24V connection is only to be used as a reference for the digital inputs – DO NOT power external
equipment from this supply rail.
Digital control inputs
The 3 digital inputs allow for overriding the dial speed setting. To set one of these inputs either:
• Connect an isolated 24V supply between DC ground and the digital input pin
• Connect the switched contacts of a relay between the 24V pin and the digital input
The fixed speeds (as a proportion of full speed) are:
Input 1 (Pin 7) Input 2 (Pin 6) Input 3 (Pin 3) Output Speed
0 0 0 Dial
0 0 24V 33%
0 24V 0 50%

Interfacing equipment to the SilensorPRO SP400BT
WARNING! A qualied electrician is required to carry out the work shown below.
The SilensorPRO SP400BT can be controlled by other equipment to turn it on to high speed (or any other
pre-set speeds, see section 8 for details). This is to achieve maximum efficiency, for example, when using a
gas heater, or a heat pump. If the equipment has an isolated 18- 24V DC signal output, simply connect pin 7
to 24V DC positive and pin 5 to DC ground as shown in the following diagram:

If the controlling equipment does not have 18-24V DC voltage output as above, but has 24V AC, 230V AC,
12V AC, or 12V DC etc. signal output, a suitable relay (the coil voltage must be the same as the signal output
voltage of the controlling equipment) can be used to do this job as mentioned above, and shown in the
following diagram:

If the controlling equipment already has the relay output (dry contact) for controlling purpose, an extra relay
is not necessary, simply connect Pin 7 (Brown/White) and Pin 8 (Brown) to the dry contacts as shown in the
left part of the diagram above.
Analogue control inputs
Speed control can also be achieved by connecting a 0-10V DC signal at the input on pin 4 (ground at pin 5).
As soon as a signal above 0V is registered, this input will take priority over dial settings. For example, 10V
DC will change pump speed pump to 100%, 5V DC will change pump speed to 50% etc.

9. USING YOUR SILENSORPRO WITH A SALT WATER CHLORINATOR
Chlorinators require a minimum flow rate through the chlorinator cell for best efficiency and cell life. Please
refer to your chlorinator guide as a reference for the flow required by your pool system. Ensure flow rate is
enough to cover your chlorinator cell plates completely at all times of operation.
10. OPERATING YOUR SUCTION POOL CLEANER
Before installing or purchasing a pool cleaner for use with your SilensorPRO, it is important to know the
minimum flow rates required for it to operate effectively.
To operate a suction pool cleaner:
• Activate the High Flow setting (10) and allow the pump to fully prime by running for around 2 minutes. You
will know the pump is primed when you can see a strong flow of water through the clear leaf basket lid.
• When all air is expelled from the leaf basket, connect the pool cleaner hose firmly into the skimmer plate or
dedicated wall suction.
• Select the speed setting that enables best performance from your suction pool cleaner. Speed 3 to 7 should
be ample for most cleaners, however if the cleaner requires better performance, select speeds 7 to 10.
• The cleaner should only be connected for as long as is required to clean the surface of your pool. When
cleaning is complete, disconnect the cleaner and remove the skimmer plate from the skimmer box.
• Reactivate the most efficient speed setting for daily filtration. Speeds 1 to 4 is recommended.
NOTE: To get optimum energy efciency from your SilensorPRO, DO NOT keep the
suction pool cleaner connected when cleaning is not required.
NOTE: If the SilensorPRO is hard-wired into a time clock, or another automatic control,
the wiring should be removed by a qualied technician.
• Close the water valves on the pool return and the SilensorPRO inlet pipework;
• Remove the discharge & suction barrel unions taking care not to lose the o-rings;
• Move the pipework with the barrel unions attached until the SilensorPRO can be pulled clear.
NOTE: When making any enquiries about your SilensorPRO be certain to quote the
model number from the nameplate located on the motor.

11. TROUBLE SHOOTING
If the pump runs but there is no water flow, or water flow is reduced, the following conditions may apply:
• The filter requires backwashing or it is blocked. Refer to the relevant section in the Filter Manual;
• The pump is not primed. Re-prime as per instruction in ‘Starting the pump’;
• There are air leaks in the suction piping. Check all piping and eliminate leaks, also check for a loose
strainer basket lid. Air bubbles in the water flowing back to the pool would indicate a leak in the suction to
the pump allowing air to enter the pipework.
• A leaking pump shaft seal may also prevent operation. Evidence of this would be water on the ground
under the pump.
• The pump is not able to get water from the pool. Check that the valves to the pump are fully open and
that the pool water level is up to the skimmer box. Typically, half way up the face of the skimmer box is
sufficient;
• Blockage in the piping or pump. Remove the strainer basket and check for any blockage to the pump
impeller entry. Check the skimmer box for blockage.
If the pump does not operate, the following conditions may apply:
• The power is not connected. For 220-240 volt only, check the power point by plugging in a portable
appliance to ensure power is available. Also check fuses and the main power supply switch;
• Automatic overload is tripped. The pump has an in-built thermal overload which will reset automatically
after the motor has cooled following an overheating period. Determine the cause of the overload tripping
and rectify. Reset the pump by switching the power OFF for 30 seconds;
• Blockage is preventing the pump from rotating.
12. REMOVAL OF THE SILENSORPRO FROM PIPEWORK
Should it be necessary to remove the SilensorPRO, follow these instructions:
• Switch off the power and remove the plug from the power source;
• Unscrew the barrel union on the front and top of the pump, releasing the pump from the pipework;
• Slide the pump out of position.

Routine Maintenance tasks - to maximise the life of your pool equipment & personal
safety, use this checklist once a week. Turn pump off rst.
a. Make sure that any pressure gauges are in working condition and the operating
pressure is within limits as specied on the product.
b. Make sure that each suction inlet and main drain has a cover that is securely
attached and in safe working condition.
c. Make sure that all skimmer covers are securely attached and in safe working
condition. These should be replaced every 3 to 4 years.
d. Remove any obstructions or debris from the main drain cover.
e. Ensure the skimmer baskets and the pump hair and lint pots are free of leaves and
debris at least once a week.
f. Remove obstructions and combustibles from around the pump motor.
g. Make sure all wiring connections are clean and that all wiring and electrical
equipment is in good condition. Damaged wiring must be repaired or replaced by a
qualied electrician as soon as damage is discovered.
