1. PREFACE
This user manual contains the operating, installation and maintenance instructions for
the ultrasonic humidier of type HU-64OG-SYS.
WARNING
It is possible that bacteria could be present in the humidier’s water supply.
Some bacteria (Legionella) could be harmful to health if they are present in
the aerosols that are blown out by the humidier.
Through the construction, ushing programme and materials used,
Contronics has ensured that the stimulation of bacterial growth is kept to the
absolute minimum. In order to ensure the supply of pure water, it is strongly
recommended that demineralised water is used (see the Contronics product
range). In conditions where bacterial pollution could occur in the surrounding
air (e.g. at meat counters) or in areas where hot ambient air could arise (e.g.
bakeries), it is also recommended to incorporate an ozone generator in the air
supply system (see the Contronics product range). Contronics cannot be held
liable for any harm caused by bacteria or micro-organisms. It is the
responsibility of the user to regularly carry out maintenance and to check the
quality of the supplied water. For these reasons a reverse osmosis lter and
an ozone generator have been included in the system.
IMPORTANT
Although the installation of this product may appear quite simple for experts,
the manufacturer urges the installer to carefully read through the instructions
before starting to install the device.

2. PREAMBLE
Introduction
The humidity in a supermarket is extremely low in the winter when the heaters are
working and in the summer with the air conditioning on.
This causes fresh products on show to lose quality quickly because they part with
moisture into the dry ambient air.
With a humidication system from Contronics you have the perfect solution for keeping
your products fresh long-term.
How do they work?
Puried water is atomized by means of high frequency waves (ultrasonic). This spray of
very small droplets is spread like a blanket over the products. The water droplets evaporate
by removing the energy from the ambient air and forming a cool moist layer just above the
product. The temperature is lowered by approx. 4-5 degrees and the relative humidity will
increase to approx. 95%. The fresh product will no longer lose moisture and is also cooled
at the same time. Your vegetables and fruit will not become wet.
Hygiene
The mains water used is puried rst so that maximum hygiene is guaranteed. A so-called
reverse osmosis lter is used for this purpose. It removes all the bacteria, viruses, calcium
and minerals that can normally be found in mains water. The system is automatically rinsed
through every hour. The humidication process stops then for a short while.
The bacteria that get into the system with the air are dealt with in a built-in ozone generator
that works at night.
Ozone (O3) is a molecule with 3 oxygen atoms. It is a strong oxidant that will kill all the
bacteria entering. In a short time it reverts to normal oxygen without leaving a residue.
Annual maintenance guarantees problem-free, hygienic use.
Parts of the system
Water treatment (LP-10), humidication (HU-64), ozone generator (OG) and drainage
system (POMPUNIT) are combined in the HU-64OG system in a stainless steel frame
for ease of installation. The system is plug and play. (See gure 1 and 2).

3. SAFETY REGULATIONS
4. PACKING
The HU system is delivered in recyclable packaging that should be kept for re-shipping
the unit for maintenance activities. Any shipment using other packaging could cause
damage to the HU for which the manufacturer cannot be held liable.
It is possible that some traces of water could be found in the packaging; all the
functions of the HU are thoroughly tested during the quality control and, for this reason,
some water could still remain in the HU before it is packed.
The package contains:
- HU system.
- Power cord.
- Instructions for use.
IMPORTANT
The humidier has an open water tank. Any overow of the water tank could
damage the electronics inside the humidier.
The following measures must always be observed:
-Always disconnect the 230 V mains voltage from the humidier before
moving it and/or carrying out maintenance activities.
-Always keep the humidier horizontal and motionless while it is in
operation and for up to 2 minutes afterwards.
-Ensure that the water is always discharged via the outlet and ensure that
this is never blocked.
-The humidier may only be dismantled by authorized Contronics
technicians.

HU-64OG-SYS
8. WATER CONNECTIONS AND FLUSHING CYCLE
Water supply
The system has an integrated ow-reduction valve and can handle a water pressure
from a minimum of 1 bar to a maximum of 6 bar. The water level in the humidier is
controlled by a oat switch and a solenoid valve.
Water outlet
The system is equipped with a pump unit and a catchment tray because there is not usually a
drain near the system. When this tray is full it will be emptied automatically.
Flushing
The standard factory setting for the ushing cycle is once every hour.
Standard cycle
The humidier’s “ushing/alarm” LED will light up every hour. The device will start the
ushing cycle:
- The fogging will stop.
- The water tank will be ushed for approx. 15 seconds (depending on the water
pressure).
- The water will be discharged.
- The humidier will be re-lled and will restart normal operation.
- The green LED will blink while this procedure is taking place.
If the humidier is switched off (230V supply voltage switched off), the water content
will be discharged to the drain unit.
9. AIR CONNECTIONS
Air outlet
The air outlet must always be extended by a 80 cm pipe to allow larger droplets to be
captured. Mount the outlet so that it slopes towards the humidier to ensure that any
condensed fog can ow back.
The connected pipe must be free from dust, dirt and oil residues. The length of the air
outlet channel to the outlet may not exceed 6m with a diameter that remains the same.
IMPORTANT
Thoroughly ush out the piping before connecting the humidier in order to
prevent installation debris from blocking the intake valve.

10. EXAMPLE SET-UP (FRESH IN FRESH OUT)
The U-pipe is placed on the frame and connected to the humidier.
The horizontal part of the U pipe has holes out of which the humidied air streams.
The longer vertical pipe contains the supply and drainage of water and electricity that is
supplied from the ceiling.
See also Fresh-in Fresh-out on www.contronics.nl
IMPORTANT
The connected pipes must be free from dust, dirt and oil residues.

11. SWITCHING ON AND STARTING UP/FUNCTIONAL TEST
Switching on
Check the following before the humidier is switched on for the rst time:
- The humidier is positioned level.
- All pipes have been properly connected.
- The mains voltage is correct.
- The water discharge channel has been connected according to the instructions.
- The water supply has been connected according to the instructions. The water
piping has been ushed in order to prevent any installation debris blocking the
water valve.
Start up and functional test
- Open the water valve.
- Set the % RH knob on maximum position.
- Switch on the power.
- Set the % knob in the desired position.
- Control if necessary the airspeed with setting 5 (gure 1).
Note: During start up and ushing (water lling) of the humidier the LED
“Flushing/alarm” will blink green.This is a normal indication on the
humidier during this procedure.
IMPORTANT
Never switch the mains voltage on if the humidier is not in the correct position
or if it is placed upside-down, as this would cause the transducers to burn.
IMPORTANT
If the humidier becomes overheated it will switch off. Once it has cooled
down it will automatically switch on again. In case of overheating,
the “Flushing/alarm” LED will show red.
The following conditions could cause overheating:
-A blockage in the air inlet.
-A blockage in the air outlet.
-Air intake temperature too high.
-Water temperature too high.
-Water discharge blocked.
-Ambient temperature too high.
-Ventilator speed set too low.

12. OZONE GENERATOR
In the HU-64OG-SYS an ozone generator is integrated. Ozone ensures that any
bacteria that are present in the humidier and the connected piping will be destroyed.
Ozone only takes effect if the humidication is switched off while the ozone generation
is taking place. A programmable timer has been incorporated in the side panel of the
humidier for switching the ozone generator and the humidication on and off.
Contronics sets the timer to a default setting of 2 hours of ozone generation at night,
between 2 a.m. and 4 a.m., while the humidier is switched off. This setting can be
changed (see “Applications”).
The blue LED indication for humidication ashes while the ozone generator is working.
The ventilator speed is then at maximum. Independent of the adjustment.
The timer is independent of the mains supply and has a rechargeable battery incorpo-
rated in the ozone module for this purpose.
The following information about the ozone generator can be found on www.contronics.nl:
- Programming the timer.
- What is ozone?
13. DRAIN UNIT
The pump unit tted in the drain unit can transport the water over a distance of
30 meters and 10 meters upwards.
14. MAINTENANCE
Regular maintenance is important for the optimum operation of the system and to
maintain hygiene.
WARNING
Ozone could be harmful to your health if the gas is inhaled over a longer
period of time in a higher concentration. However, this concentration only
occurs inside the humidier and the connected piping. Once discharged, ozone
gas quickly breaks down into ordinary oxygen, without any residual products.
WARNING
If these batteries have to be replaced, the old battery must be disposed off as
chemical waste or, alternatively, returned to the manufacturer.

HU-64OG-SYS
Humidier
The maintenance interval of the water reservoir will depend on the quality of the water and the
purity of the air that is sucked in. Contronics advises al least 1 x year maintenance.
The transducers must be replaced after approximately 20,000 operating hours (i.e. after about
2 years in the case of continuous use).
Check the following before starting maintenance or shipping the humidier:
- The mains plug has been removed from the socket and the ventilator is not
moving.
- The water supply has been closed.
- The water supply pipe has been removed.
- The humidity sensor plug has been removed.
- The water reservoir is empty and the water discharge hose has been removed.
- The humidier remains horizontal while dismantling.
Cleaning
- Remove the connecting ange.
- Clean the reservoir with a soft brush or cloth.
In the case of water scale, the reservoir can be lled with household vinegar. Allow
to soak for 4-12 hours then clean with a soft brush and ush through. Remove the
lter from the water inlet. Clean the lter or replace it with a new one. Flush the water
discharge with water and clean it with a round brush.
R.O. system
Some maintenance is necessary in order to guarantee the long service life of the
system. Normal maintenance consists of replacing the sediment lter and the active
carbon lter(s). This should be done at least once a year if the humidier is in
continuous use. If the supply water is heavily polluted with minerals or chlorine,
however, it is recommended to do this more often.
Checking the demineralised water
- Take a sample of the supply water.
- Measure the conductivity of the supplied tap water using a micro-siemens meter.
- Take a sample of the demineralised water.
- Measure the conductivity of the demineralised water using a micro-siemens
meter.
- Divide the value found for the demineralised water by the value found for the
supplied tap water and multiply the result by 100%:
< 10%: the water quality is good
Between 10% and 20%: the water quality is acceptable
> 20%: the water quality is poor – replace the membrane.
- If the micro-siemens value for the supplied tap water is >500 uS, it is
recommended to install a de-scaling system ahead of the R.O. system.
IMPORTANT
Make sure that the transducers are not damaged during cleaning.

HU-64OG-SYS

Checking the buffer tank
If the buffer tank is not completely lled during the start-up procedure, it is possible that
the pressure in the tank is too high compared to the pressure of the supplied water.
In this case it is possible to release some of the (air) pressure step-by-step via the
valve situated underneath the tank under a black cap, until the tank is lled. It is also
possible to measure the pressure with the same kind of meter that is used for car tyres.
To check that the pressure is not too low, the tank must be disconnected with the tap
closed. Open the tap in an area where this is possible and allow the tank to empty
completely.
If the pressure is too low, it is possible to increase the pressure using the valve and
the same system that is used to increase the pressure in car tyres. The pressure is
normally adjusted to 0.45 bar.
Procedure:
Before replacing the lters, the system must be de-pressurised.
1. Switch the humidier off.
2. Close the supply tap.
3. Close the tap on the storage tank.
4. Disconnect one of the tubes from the storage tank and collect the excess water.
5. Exchange the lters by unscrewing the lter holders.
Beware: The lter holders still contain water.
6. Before re-installing the lters, the O-ring must be checked for damage and correct
seating.
7. The holders can be cleaned with soap and water or with chlorine, if necessary.
Rinse thoroughly afterwards.
8. After re-installing, screw the holders back into place (hand-tight!).
Starting up again:
1. Open the supply tap and let the system ush through for about 5 minutes (in order
to ush out any air).
2. Supply voltage to the pump.
3. Reconnect the tube to the storage tank.
4. Open the tap on the storage tank.
5. Wait until the system reaches the correct pressure (the discharge water will stop).
6. Switch the humidier on again.
Ozone generator
The ceramic element must be cleaned once a year:
- The humidier must be disconnected from the mains.
- Remove the screws on the side where the timer is located.
- Remove the side panel and disconnect the timer.
- Remove the 2 Phillips screws (bottom and top) from the stainless steel cover
plate (on the black aluminium casing).
- Remove the ceramic element from the holder.
- Carefully clean the ceramic element on both sides with cleaning spirit or alcohol.
- If the vapour-deposited metal on the ceramic element is damaged, replace the
ceramic element.
- Re-assemble in the reverse order.

Replacing the transducers
The replacement of the transducers can only be done by Contronics or representatives
authorised by Contronics.
Drain unit
The HU-64OG-SYS has a drain unit to catch the waste water and pump it away to the
drain. The pump unit requires little maintenance. Only the XP STAYCLEAN has to be
replaced annually. The XP STAYCLEAN deals with the disinfection in the drain unit.
Figure 6. shows where the XP STAYCLEAN should be tted.

17. OPTIONS LP-10WS, LP-10WSG, LP-10WSWSG, LP-10BP and HTR-10
This extra manual shows specic operation, installation and maintenance instructions for
the LP-10WS, LP-10WSG and de LP-10WSWSG options.
LP-10WS is an LP-10 combined with
a permeate pump. The pump, that is
water-powered, ensures that the rin
sing water is used more efciently.
The LP-10 needs 30 litres of rinsing
water to produce 10 litres of
demineralized water. The LP-10WS
only uses 20 litres for this.
The LP-10WS saves 85 m3 on an
annual basis.
See graph and specications page 21.
Figure 7. LP-10WS
The LP-10WSG continuously monitors
the membrane function. Normally the
membrane would be checked 1 x a
year. This is now done automatically
and an indication is given when the
membrane needs replacing. If the
quality of the membrane gets below a
certain value, the humidication system
that is connected to the LP-10WSG will
be switched off.
See specications page 21.

The LP-10BP is used when the
water pressure is < 3 bar.
See specications page 21.
Figure10. LP-10BP
The HTR-10 is a room hygrostat and
remote control for the HU-xxx series
of air humidiers.
A very accurate air humidity sensor
and temperature sensor are built-in.
The humidity sensor is also very
accurate in the higher regions of the
relative air humidity.
A built-in heating element in the
sensor element ensures that the
sensor stays dry when the dew point
is reached.
The heart of the electronics is a
