1 Introducon
These operang instrucons provide you with informaon
about all technical and safety-relevant aspects that you must
be familiar with for using iFerm Nano Tank.
¨Read the operang instrucons in full before operang
the unit, and also use them for the purpose of instrucng
all users.
1.1 Proper use
iFerm Nano Tank is designed for measuring and controlling
process temperatures in beverage producon. Normal
operaon involves regulang the supply of refrigerant as
required, which in turn guarantees maintenance of the
setpoint temperatures in fermentaon processes.
Temperature control applicaons for processes such as
ltraon, boling, tartrate stabilisaon, room temperature
control and stock cooling are sll deemed to be proper. Use
for other purposes is only permissible if the manufacturer’s
wrien approval has been obtained for the actual situaon.
For installaon, iFerm Nano Tank is placed into a
thermowell on the tank with the preinstalled temperature
probe. Operaon and conguraon 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 deviaon results in
an adjustment of the connected valve that controls the ow
to the heat exchanger in the tank.

Introducon
In conjuncon with the oponally 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 funcons such as the
monitoring of heang processes.
1.2 Prior knowledge
In the operang instrucons, users are dened as all
persons who are involved in the installaon and operaon
of the iFerm Nano Tank. Users must be at least 16 years of
age. They must have read and understood the operang
instrucons and must be able to follow all noces and
instrucons.
The operang instrucons are intended for persons with
experience in handling comparable measuring instruments
and systems. In parcular, basic knowledge of beverage
producon is required.
1.3 Notesabouttheoperanginstrucons
The following typographical elements are used in the
operang instrucons in order to nofy you of possible
hazards or parcular informaon:

All stated posions (le, right, front, back, top, boom
etc.) relate to an observer looking at the display of
iFerm Nano Tank from the front. The connecng cable is
therefore at the boom, the display in front.
2 Safetynoces
yRead the operang instrucons carefully and obey all
safety noces. Material damage resulng from ignoring
the safety noces is not covered by any warranty.
yWhenever you use iFerm Nano Tank, follow the laws
that apply at the place of use, parcularly the general
safety and accident prevenon regulaons. If in doubt,
these take precedence over the direcons in the
operang instrucons.
yiFerm Nano Tank is operated with 24 V AC, 50/60 Hz
safety low voltage, see “4.2Aachingtheconnecng
cable” on page 18. The power supply must be
properly connected and then checked and approved by
a qualied electrician. There is a risk of electric shock if
the connecon is faulty!

Product overview
yExtreme temperatures caused by heat build-ups, frost,
UV light, direct sunlight etc. can cause irreparable
damage. Always maintain the specied ambient
temperatures, see “8.1Technicaldata”onpage27.
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 sucient strain
relief and kink protecon.
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 instrucons in the chapter “7Maintenanceandcare”
on page 26.
3 Product overview
iFerm Nano Tank keeps the process temperature in the tank
constant to the value of the specied target temperature,
as long as the cooling or heang medium required for this
is constantly available in a sucient quanty. To achieve
this, the temperature probe sends the measured actual
temperature to the microprocessor that adjusts it to the
target temperature. Every deviaon results in an adjustment
of the valve seng so that the tank’s heat exchanger can be
lled as required and the target temperature is maintained in
every process phase.

Product overview

Since fermentaon yeasts react sensively to frequent
temperature changes, iFerm Nano Tank intervenes in
fermentaon 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
dierence between the actual value and the target value.
In the event of major deviaons, the pulse/pause rao can
be regulated in such a way that the valve is permanently
open. The controller detects temperature deviaons that
occur mainly in the inial vibraons range, and counteracts
them automacally by connually restricng the controller
tolerance. Aer 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 buons, see “5Operaon”onpage20. Other
changes are not possible unl aer enabling, see “6 Extended
conguraon”onpage22.
