Congratulations on your purchase! Thank you for buying a LILIE pump.
Pumps are the heart of any camper van and caravan water installation. The long-life diaphragm pumps quickly build up
pressure in the closed water system and thus move the water through the pipes. Our pumps are manufactured by our
partners according to our development specifications, which are based on over 30 years of experience.
In this manual, you’ll find all the information you’ll need to install and reliably operate your LILIE pump.

1Installation situation and use
You’ll get the most pleasure and greatest benefit out of the pump if you use it as a complete system that has been
specifically developed and optimised for this area of use as opposed to individually – or supplemented by individual
additional parts. We recommend that you use our LILIE WeißGELB® drinking water system for this purpose. In our
catalogue (available at www.lilie.com), you’ll find suitable connection and installation material for your LILIE pump in
the ‘Water tuning’ section.
The pumps are designed for use in the dry interior of a camper van. They are not watertight or resistant to splash water
or acids.
The pumps described in this manual are designed for intermittent operation and are not suitable for continuous
operation. The switch-on duration and length of the intervals can be found in the complete overview of the pumps in our
current catalogue. Our pumps for the caravanning sector can run for 20 minutes at a time without any problems, after
which a longer break is necessary.

2Installation
The assembly process is intended to make operating the pump as quiet as possible while guaranteeing sufficient
pumping characteristics, the lowest possible pressure load and easy access for maintenance work. This can be
achieved by following the instructions below.
2.1 Positioning the pump
Generally speaking, we recommend assembling the pump in a heated raised floor. Where this is not possible, the pump
should be installed on the base plate. Assembly in cabinets, on benches, on thin toilet walls and generally on vibration-
transmitting resonating bodies and surfaces should be avoided in any case.
For optimum performance, the pump’s installation location should meet the following criteria:
•As close to the tank as possible, or two metres away at most
•An easily accessible location (easy access to the coarse filter during maintenance)
•Free space that’s as open as possible, with a clearance of 10 cm on all sides (sufficient ventilation and
protection against overheating)
The pump can be assembled in an upright or a suspended position; if assembled in a suspended position, the pump
head should be facing downwards, so that – in the unlikely event of a leak – any water escaping cannot get into the
motor.
Please choose a solid, stable surface (e.g. thick plywood) that does not transmit the pump’s vibrations. Padding under
the pump improves noise insulation. The pump bases insulate the pump against the assembly surface; not screwing in
the fixing screws on the base plate too tightly reduces the noise level.
2.2 Connections and peripheral devices in the water system
Please ensure that all of your water system’s components can withstand your pump’s maximum pressure.
2.2.1 Connections and sleeves
The pump’s connections and the thread of the associated LILIE sleeves are coordinated to one another and are
manufactured with the highest precision. The system is designed to be 100% tight without any additional sealing
components. Please use only the original connecting sleeves (e.g. LILIE WeißGELB® screw-on sleeve in the 12 mm
variant: #8042 or #8044 or in the 10 mm variant: #8040 or #8043) and refrain from using Teflon tape or other sealing
components. This can lead to damage to the connecting thread and leakage.
Our quick couplings (quick fittings) for the SMARTSERIE® with O-rings ensure quick removal when maintenance or
access is required.

2.2.2 Hose system
If possible, please use our flexible LILIE native or LILIE Eco native drinking water hoses with the largest possible inner
diameter (min. 10 mm, ideally 12 mm) that have been tested according to DIN 2001-2. The LILIE native drinking water
hose cushions and reduces vibrations the best in this respect. You can find our drinking water hoses (e.g. #88112 LILIE
native 12x18 as the ‘ideal hose’) in the ‘Water tuning’ section of our catalogue. Smaller pipe diameters can lead to
cavitation, increased pressure resistance, a restricted delivery rate and increased operating noise.
Our drinking water hoses are very quiet compared to pipe systems. If a pipe system is installed nevertheless, you can
reduce the vibrations by using a piece of hose measuring min. 50 cm in length between the pump and the pipe. When
rigid pipes are connected directly to the pump, the pump’s operational vibrations may be amplified, resulting in louder
operating noise and cavitation, leakage or defects in other components.
2.2.3 Complete system and inner diameter / flow optimisation
A straight course and gentle bends and curves in the hoses or pipes allow the water to flow quickly and conveniently.
Please, therefore, avoid tight bends or corners in the pipes, especially directly upstream and downstream of the pump.
•Constrictions in the pipe cross-section, especially in the pump inlet and outlet, should be avoided if possible.
•This also applies to shut-off and drain cocks, as well as elbow connections with a smaller inner diameter.
•Please use water taps with a large outlet. We recommend using 35 mm cartridges at least, but 40 mm ones are
better.
2.2.4 Water distribution block and connector
Please use a water distribution block with a correspondingly large inner diameter, e.g. our flow-optimised water
distribution block #24207 LILIE WeißGELB® five outflows instead of individual T-pieces.
The fewer connectors used in the water installation, the better and more reliable the overall water flow. Please,
therefore, use as few connectors as possible. Where necessary, please use connectors with a high flow rate, e.g.
#69510 LILIE WeißGELB® Y-connector.
2.2.5 Pre-filter
Please use a suitable pre-filter with 50-mesh, a mesh width of approx. 0.25 mm, to prevent contamination of the pump
with dirt particles, e.g.
•for CLASSICSERIE™ and SOFTSERIE®: #LS200162 ½” screw-on filter
•for SMARTSERIE™: #200155 pre-filter with quick fittings
2.2.6 Fasteners
When laying ring pipes, please ensure that vibration-reducing fasteners are used, e.g. #50309 Lilie WeißGELB®
fastening clamp.
2.2. Drinking water filter
•We recommend using our Certec® filter unit | 10” (#20593) or the LILIE biolit 97 filter unit (#20293) because
they are coordinated to the LILIE WeißGELB® drinking water system and the pumps for the caravanning sector.
Place drinking water filters on the pump’s pressure side (not in the suction pipe).
•Filter units generally have a pressure-reducing and flow-reducing effect in the water system. This phenomenon
is minimised with Lilie filter units. In this case, the SMARTSERIE™ pumps throttle the delivery rate.
•If your application requires the use of a filter unit with a high pressure loss, it may be advisable to use a
stronger pump.
2.2.8 Pressure compensation tank
•If you are using a CLASSICSERIE™ pump in your system, we recommend that you use a pressure compensation
tank (e.g. #LP1805 pressure compensation tank).
•No pressure compensation tank is required in connection with SOFTSERIE® and SMARTSERIE™ pumps. If you
do not want to dismantle your existing pressure compensation tank, we recommend that you depressurise it.
2.3 Electrics
Please connect the pump to the battery and install a circuit breaker. We recommend fusing with a 15 A fuse in the (red)
positive line. When used in the marine sector, a UL-approved marine switch should be used.
The cross-section of the cables used for power supply and earthing depends on the distance between the pump and the

power source:
•0 m – .5 m 1.5 mm² or AWG 16 (AWG = American Wire Gauge)
•.5 m – 20 m 2.5 mm² or AWG 14
•20 m – 30 m 4.0 mm² or AWG 12
The pump must be earthed, e.g. on the vehicle frame or at the battery’s negative pole.
If your camper van has a whisper control or a similar control device, it must be designed for the pump’s maximum
current consumption.
Never remove or bypass the fuse integrated in the positive line; it protects the pump’s electronics.
We recommend that you switch off the power supply to the pump when you leave your camper van or when it is
unattended.
3Indi idual settings on the pump
The pressure switch and bypass are preset at the factory. Usually, they don’t need to be adjusted. If your specific
operating conditions require adjustment, please proceed as follows:
3.1 CLASSICSERIE™ – pressure switch
The pump’s shutdown pressure can be increased or decreased to a limited extent (0.5 bar / psi). The shutdown
pressure …
•can be increased by turning the screw in the middle of the pump head clockwise.
•can be reduced by turning the screw in the middle of the pump head anti-clockwise.
Start with small changes (max. half a turn). Avoid major changes and turning it clockwise or anti-clockwise all the way.
This can permanently damage the pump.
3.2 SOFTSERIE® – pressure switch and bypass
The mechanical bypass control reduces the pump’s delivery rate if the possible flow rate is reduced, e.g. at the tap. The
bypass value is preset and is approx. 0.3 bar above the pump’s shutdown pressure. The pressure switch and the bypass
control are optimally coordinated to one another to ensure the pump’s optimum pumping characteristics. When making
adjustments, both values must therefore always be adjusted appropriately.
If the pressure switch is set too high, it may not switch off. The shutdown pressure …
•can be increased by turning the screw in the middle of the pump head clockwise.
•can be reduced by turning the screw in the middle of the pump head anti-clockwise.
If the bypass value is too low, the pressure switch’s switching point can no longer be reached and the pump no longer
shuts down. The value that the bypass starts to work at
•can be increased by turning the screw on the bypass clockwise.
•can be reduced by turning the screw on the bypass anti-clockwise.
3.3 SMARTSERIE™
The pump’s electronics and the whisper control regulate the motor speed and the pump’s delivery rate as needed, thus
ensuring low noise levels and power consumption. This means previously unknown, precise water delivery as required,
without loud starting noises, splashes or abrupt fluctuations.
There is no need and no option for individual settings for the SMARTSERIE™ pumps.
4Start-up
The drinking water pumps are delivered in a dry state to avoid microbial contamination inside the pump during
transport and storage. This means that the pump requires slightly more time to suck in water from the dry state when it
is first started up.
5Disinfection
We recommend disinfecting the entire drinking water system with hydrogen peroxide when the system is started up and

once a year, or at shorter intervals if the pump is subjected to intense use. You are welcome to use the #56200 Lilie DW
disinfectant for this purpose. Please proceed as follows:
1. Pour the required amount of LILIE DW disinfectant into the tank
2. Fill the tank with water
3. Set the pump switch to <OFF>
4. Open all tapping points
5. Switch on the pump using the pump main switch
6. Close the tapping points when water is running from all tapping points. The pump now shuts down
automatically.
. Allow to stand for at least six hours (observe the exposure time with regard to tank size and concentration)
8. Once the contact time has elapsed, drain the contents of the tank. Fill the system with fresh water and rinse the
disinfectant solution from the entire drinking water system.
9. Please also observe the manufacturer’s instructions for the disinfectant used, especially for the correct dosage.
The described procedure corresponds to the German Drinking Water Ordinance according to DIN 2001-2, which is also
valid for the entire European Union.
6Maintenance
Drinking water systems require regular maintenance to ensure an even flow of drinking water. The following measures
should be performed regularly:
•Clean your installation’s pre-filter with clear water
•Clean the aerators of the taps and shower heads
•Check and clean the coarse filter
•Clean / disinfect the pipes
•Check screw connections to see if there are any leaks or cracks
If there is a risk of frost, the pump and the pipes should be protected against freezing, e.g. by draining or filling with
suitable antifreeze (see the following section).
Lack of maintenance is one of the most common causes of loss of performance and premature pump failure. Deposits
on valves and diaphragms may lead to loss of flow or internal leakage over time. An indicator for this is – for example –
the pump occasionally, briefly starting even though there are no consumers active.
For appropriate measures, please also refer to the relevant information from your camper van manufacturer!
7Winterproofing the pump
If water freezes in the hose or pipe lines, this can damage the pipes and the pump. The best protection against frost
damage such as this is a non-toxic antifreeze for fresh water, e.g. #56601 Winter Ban antifreeze available from the
camper van centre.
1. Open all tapping points and completely empty the tank
2. Close all tapping points
3. Pour at least ten litres of a mixture of Winter Ban and water into the tank.
4. Then open the tapping points individually until coloured liquid emerges.
5. Close all tapping points; switch off the pump main switch.
 Do not use car antifreeze to winterproof drinking water pipes. These solutions are highly toxic. Swallowing a
solution such as this may cause injury or death.
You can also drain all the water from the system:
1. Empty the water tank. If there is no drain valve on the tank, open all taps and use the pump (or alternate
between running for 15 minutes and taking a break for 15 minutes) to completely empty the tank.
2. Open all taps (including the valve or drain located at the lowest point in the pipe system) and pump out the
water remaining in the pipes. Then switch off the pump.
3. Disconnect the pipe system from the pump at the inlet and outlet connection and collect the remaining water in
a tub.
4. Switch the pump on again and let it run until all the water has been removed.
5. All taps must remain open to prevent frost damage caused by residual water in the system.
