1. INTRODUCTION
The use of demineralised water is recommended with Contronics humidiers for the
following reasons:
- Any minerals, salts and bacteria that enter the humidier will cause the water
reservoir to become polluted. The integrated ushing programme will delay this
process but will not prevent it entirely.
Depending on the quality of the added water, the water reservoir will eventually
become blocked. As a result, the energy of the transducers will no
longer be effective, and they will wear out more quickly. In addition, the oat
switch could transmit the wrong information to the electronics system, thereby
causing damage to the electronics.
- The minerals and salts (calcium) present in the water will end up in the area to be
humidied and could cause annoying deposits of dust.
- Any bacteria present in the water (Legionella) could multiply easily in the relatively
warm water in the tank and could thereby constitute a health hazard.
The use of demineralised water reduces:
- Maintenance
- Wear and tear to the transducers
- Deposits of dust in the area
- Bacterial growth
System components
The Contronics LP series is tted with a high-quality (Dow Chemical) membrane.
Working on the principle of Reverse Osmosis (R.O.), the membrane only allows water
molecules to pass through. A ushing system prevents clogging, increases the service
life of the membrane and improves performance.
Systems can be supplied with a capacity of 375 – 3,600 l per day (at a temperature of
25°C and depending on the water pressure).
Two preliminary lters are positioned ahead of the membrane: a 5 micron pre-lter and
an active carbon lter.
In the BP version, an electric pump has been added to increase the capacity in order to
cope with low water pressure or higher consumption.
The system also incorporates an automatic shut-off valve. When the system does not
need to supply demineralised water and is at the correct pressure, this will ensure that
the supply water will be shut off in order to prevent water from being unnecessarily
wasted through ushing.
A buffer tank is also included in the delivery (including the T-piece connector) and must
be tted in the supply line to the humidier. This tank will supply additional water
whenever the humidier is consuming more than the osmosis system is able to supply.
This occurs during ushing and lling. At any other time, the system supplies more
than the required consumption and any excess water will be used to top-up the tank.
The tank incorporates a rubber bag in which the demineralised water is stored. The air

pressure is higher between the bag and the external shell.
In the LP-30BP, LP-60BP and LP-100BP models, an electronic water leakage detector
is supplied that will cut off the water supply if any leakage is detected.
2. KNOW YOUR REVERSE OSMOSIS (R.O.) SYSTEM
Before starting the installation, take a few moments to become familiar with the names
of the components. Compare the device you have unpacked to the drawing below.
Once you are familiar with the lay-out, you can start the installation.

5. INSTALLATION PROCEDURE
Place the device in a suitable location. Place the pre-lter (for LP-30BP/60BP/100BP 2 x)
in the left-hand holder.
Place the carbon lter in the right-hand holder (remove the cellophane).
When doing this, ensure that the O-rings on the holders are seated correctly.
The carbon lter is tted with a at rubber ange at the top and the bottom.
Remember to make allowance for the connections for the water supply, discharge,
buffer tank and socket. It is recommended to t the device against the wall in the
vertical position. This will speed up the air bleeding and will enable easy replacement
of the lters. Although it is possible to mount the device in a horizontal position, the
preferred position is vertical with an eye to the easy replacement of the pre-lters.
Supply water connection:
WARNING
Do not place an automatic stop valve in the water supply to the R.O. system.
No inlet pressure, or inadequate inlet pressure, can damage the pump and/or
motor.

Check that the supply pressure is at least 2 bar. Where the inlet pressure < 2 bar it is
recommended to install a device incorporating a booster pump (BP).
For maximum performance, the inlet pressure must be a minimum of 4 bar for the
LP-10.
Connect the R.O. unit to a washing machine tap with an air bleed valve. The R.O. unit
has a shut-off tap in the water supply with 1/4” inner thread. A shut-off valve ensures
that the water supply is cut off when the buffer tank is completely full and no water is
being consumed.
R.O. water connection:
1. Fit a 3/8” tube from the R.O. water connection (Figure 6) to the T-piece and from
the T-piece to the inlet valve on the storage tank.
2. Fit a tube from the T-piece to the humidier. The ¾” connection coupling to the
humidier is included in the delivery.
Discharge connection:
Fit a tube (1/4” minimum) from the discharge connection (Figure 6) to the drain.
Important: Always leave a gap between the discharge tube and the drain in order to
prevent the water from owing back into the R.O. system.
Electrical connection (BP model only):
Insert the plug into the socket.
6. WATER DETECTION CIRCUIT (LP-30BP/60BP/100BP)
Position the water detector in an area where you would expect water to collect rst in
case of a leak. If the surface here is conductive, rst lay an insulating layer. If the water
detector detects a leak, the supply valve to the system will be closed immediately. It is,
however, possible that the content of the buffer tank will continue to leak (10 l water).
A reset button has been located on the electronics housing; if this button is briey
pressed, the system will be re-activated.
In addition, a connection for an external alarm is also provided on the electronics
housing in the form of a potential-free contact.
WARNING
Use only plastic or stainless steel tubing for demineralised water.
