1 Introducon
These operang instrucons provide you with informaon
about all technical and safety-relevant aspects that you must
be familiar with for using iFerm Nano Tank.
¨Read the operang instrucons in full before operang
the unit, and also use them for the purpose of instrucng
all users.
1.1 Proper use
iFerm Nano Tank is designed for measuring and controlling
process temperatures in beverage producon. Normal
operaon involves regulang the supply of refrigerant as
required, which in turn guarantees maintenance of the
setpoint temperatures in fermentaon processes.
Temperature control applicaons for processes such as
ltraon, boling, tartrate stabilisaon, room temperature
control and stock cooling are sll deemed to be proper. Use
for other purposes is only permissible if the manufacturer’s
wrien approval has been obtained for the actual situaon.
For installaon, iFerm Nano Tank is placed into a
thermowell on the tank with the preinstalled temperature
probe. Operaon and conguraon are performed via
the integrated display that always shows the process
temperature and current messages. The actual temperature
in the tank is measured and adjusted to the set target
temperature by a microprocessor. Every deviaon results in
an adjustment of the connected valve that controls the ow
to the heat exchanger in the tank.

Introducon
In conjuncon with the oponally available control unit
iFerm Nano Terminal you can operate iFerm Nano Tank
centrally (only the 24 V AC, 50/60 Hz +
data bus version). iFerm Nano
Terminal can access up to
30 controllers of the iFerm Nano
series and can also use them for
special funcons such as the
monitoring of heang processes.
1.2 Prior knowledge
In the operang instrucons, users are dened as all
persons who are involved in the installaon and operaon
of the iFerm Nano Tank. Users must be at least 16 years of
age. They must have read and understood the operang
instrucons and must be able to follow all noces and
instrucons.
The operang instrucons are intended for persons with
experience in handling comparable measuring instruments
and systems. In parcular, basic knowledge of beverage
producon is required.
1.3 Notesabouttheoperanginstrucons
The following typographical elements are used in the
operang instrucons in order to nofy you of possible
hazards or parcular informaon:

iFerm Nano Tank from the front. The connecng cable is
therefore at the boom, the display in front.
2 Safetynoces
yRead the operang instrucons carefully and obey all
safety noces. Material damage resulng from ignoring
the safety noces is not covered by any warranty.
yWhenever you use iFerm Nano Tank, follow the laws
that apply at the place of use, parcularly the general
safety and accident prevenon regulaons. If in doubt,
these take precedence over the direcons in the
operang instrucons.
yiFerm Nano Tank is operated with 24 V AC, 50/60 Hz
safety low voltage, see “4.2Aachingtheconnecng
cable” on page 18. The power supply must be
properly connected and then checked and approved by
a qualied electrician. There is a risk of electric shock if
the connecon is faulty!

Product overview
yExtreme temperatures caused by heat build-ups, frost,
UV light, direct sunlight etc. can cause irreparable
damage. Always maintain the specied ambient
temperatures, see “8.1Technicaldata”onpage27.
yiFerm Nano Tank is protected against water jets (IP65).
However, avoid intensive contact with liquids (e.g. high-
pressure cleaners).
yLay cables so that they do not present a trip hazard and
away from sharp-edged objects. Ensure sucient strain
relief and kink protecon.
yClean the iFerm Nano Tank with a so damp cloth. Do not
use any aggressive, scouring cleaning agents or cleaning
agents containing solvents.
yDo not perform any repairs on iFerm Nano Tank. Follow
the instrucons in the chapter “7Maintenanceandcare”
on page 26.
3 Product overview
iFerm Nano Tank keeps the process temperature in the tank
constant to the value of the specied target temperature,
as long as the cooling or heang medium required for this
is constantly available in a sucient quanty. To achieve
this, the temperature probe sends the measured actual
temperature to the microprocessor that adjusts it to the
target temperature. Every deviaon results in an adjustment
of the valve seng so that the tank’s heat exchanger can be
lled as required and the target temperature is maintained in
every process phase.

Product overview
Subject to change. |
Since fermentaon yeasts react sensively to frequent
temperature changes, iFerm Nano Tank intervenes in
fermentaon processes even before the target temperature
is reached and starts the cooling. Brief cooling pulses gently
slow down the temperature rise, and exceeding of the target
temperature is prevented by more intensive cooling.

Time
The frequency of the cooling pulses varies depending on the
dierence between the actual value and the target value.
In the event of major deviaons, the pulse/pause rao can
be regulated in such a way that the valve is permanently
open. The controller detects temperature deviaons that
occur mainly in the inial vibraons range, and counteracts
them automacally by connually restricng the controller
tolerance. Aer a short me, a stable target temperature is
arrived, at which the tank contents can be reliably kept.
The actual and target temperature can always be read o
on the display. The target value can simply be adjusted via
the display buons, see “5Operaon”onpage20. Other
changes are not possible unl aer enabling, see “6 Extended
conguraon”onpage22.
