GENERAL INFORMATION
Enjoy your LILIE water pump for years to come!
For us at LILIE, the most important thing is customer satisfaction.
With this product you have acquired a great pump that we have developed in over 30 years. It is made of special materials which comply
with the drinking water ordinance according to DIN 2001-2.
Please use your new pump only corresponding to this manual! If you do so, you will be able to reliably enjoy our products long-term, like
the other hundreds of thousands of satisfied customers.
Please note:
Caravaning pumps are developed for application in the dry interior of a motor home. They are not splash-proof or acid-resistant. The
pumps have no splashguard according to IP ff. Our Boat pumps are constructed for use in seawater environments. However, that does not
mean they can be used standing or submerged in water. No warranty shall be accepted for damage caused by inappropriate or improper
use or operation, or faulty installation. This includes continuous operation. These pumps are not suitable for continuous or permanent use
but have been specially developed for intermittent operation.
The power-on time and interval lengths of the pump in use depend according to the specifications in our current catalogue. A caravanning-
pump, e.g., may run smoothly for up to 20 minutes, after which a longer pause is necessary. (Generally, the fresh-water tank of your motor
home would already be empty.)
It is very important to tighten the screws, which may have become loose by cause of vibrations and movements, from time to time. Check
the screw fittings regularly; many problems can be solved or avoided this way.
INSTALLING THE PUMP
The aim of the installation is to achieve the most silent pump operation, with efficient conveying behavior, the lowest possible pressure load,
and easy access to maintenance work. By following the instructions below, these results can be achieved.
The pump should be installed on a stable surface with sufficient accessibility, for easy access to the coarse filter during maintenance.
•
Use suitable flexible pressure-resistant hoses in the input and output of the pump, e.g. our LILIE Native.
•
No rigid, plastic or metal piping should be used for the pump input and output, as well as the coarse filter.
•
Otherwise, the operating vibrations of the pump can be amplified, which can lead to loud operating noise as well as cavitation, leaks,
or even defects on other components.
•
Use only original grommets (e.g. LILIE 12mm: #8042, #8044; 10mm: #8040, #8043) without further use of Teflon tape or another sea-
lant. The use of these means, as well as the use of other connections, can lead to leaks or damage to the pump. Such damage is not
covered by the warranty of the pump.
•
On the input side, the pump should be protected by a suitable coarse filter (50-mesh, mesh size approximately 0.25mm, e.g., LILIE #
LS200162) to prevent particles from entering.
•
Mount the pump on a stable surface to avoid vibration and noise.
•
Hose lines should have an inner diameter of ideally at least 12 mm. We recommend our LILIE Native Drinking Water Hose #88112 or
#98112. Smaller pipe diameters can lead to cavitation, increased pressure resistance, reduced flow and an increase in operating
noise.
•
Please avoid restrictions on the diameter of the plumbing at the inlet and outlet side of the pump as much as possible.
•
This also applies to shut-off and drain valves, as well as angle connectors with smaller inner diameter.
•
You don’t need a pressure compensation tank when using a pump of the
SOFT
SERIE
®
or
SMART
SERIE
™
.
•
This pump is designed for intermittent use only. Don’t use the pump for a reverse osmosis system. High pressure and non-stop opera-
tion shorten the life cycle of the pump. Such use is not covered by the warranty.
•
The diameter of the cables should be 1.5mm² at minimum; we recommend 2.5mm² or 4.0mm². (See respective diagram in section
“Electrical Connection”)
•
If your motor home has any control device (such as LILIE article #18501) installed, it has to be designed to meet the pump’s maximum
power consumption.
•
In order to achieve best the possible performance and operational lifetime of the pump, mount it within a distance of maximum 2m
from the fresh water tank.
•
In order to properly ventilate and protect against overheating, the pump should be mounted at a location with 20l (0.02 m
3
) or more of
free space.
•
The pump can be mounted in a vertical or horizontal position. If mounted in a vertical position the pump-head must be pointed down-
wards.
•
The installation site should be easily accessible to facilitate maintenance work such as emptying the coarse filter.
