6 Rittal Thermoelectric Cooler assembly and operating instructions
4 How it works
GB
4 How it works
The Rittal Thermoelectric Cooler uses the Peltier effect for cooling. This effect is based on the principle
that an electric direct-current flowing through a circuit consisting of two different metals causes the
cooling of one contact point and the heating of the
other contact points. An appropriate layout for the
cooling production is designated as Peltier element.
When the Peltier effect is used for enclosure climate
control, an air flow is fed over the upper and lower
connection point. The heat energy is released or
accepted from the air flow to the Peltier element.
The air flow that releases the heat energy to the element is introduced as cooling air flow in the enclosure or the operating housing. After
the heating of the
cooling air flow by the active installed equipemt
, it is
returned to the cooling unit and fed for renewed cooling over the “cold” side of the Peltier element. This
produces an air circulation that causes the cooling of
the enclosure or the operating housing.
The air flow that accepts the heat energy from the
“warm” side of the Peltier element is released as
warm air flow to the external air circuit of the cooling
unit. This means the heat produced by the components in the enclosure is dissipated to the ambient air
surrounding the cooling unit.

Rittal Thermoelectric Cooler assembly and operating instructions 7
GB
5 Control
The Rittal Thermoelectric Cooler controls the cooling
capacity of the Peltier elements and the air throughput of the integrated fans so that the required internal
temperature of the enclosure or the operating housing is set with high accuracy. For this purpose, the
device permanently monitors the air entry temperature at the warm air entry (internal circulation). If this
temperature exceeds a parameterised temperature
value (factory setting: 35°C), the device starts cooling operation. To do this, the trigger voltages of the
Peltier elements and fans are corrected by a PID
control so that the cooling capacity required for the
cooling is always available and the cooling operation
is provided with the least possible power. The redundant fans in the external air circuit of the Rittal Thermoelectric Cooler have variable air delivery rates
(and consequently variable speeds) appropriate for
the required cooling capacity. If only limited or indeed no cooling capacity is required, this control behaviour can lead to a temporary inactivity of the fans
in the external air circuit. This does not constitute
a malfunction of the device, but rather an extreme
power-saving operating state that also increases the
service life of the used fans.
Note:
The fan speed in the external air circuit of
the cooling unit is matched to the current
cooling capacity requirement.
Consequently, a stoppage of the fans –
interrupted by periodic, short-term fan
starts – is not a malfunction of the device,
but rather represents an extreme powersaving operating state!

GB
7 Device mounting
The following principles must be observed for determining the mounting position on the enclosure or operating housing:
The Rittal Thermoelectric Cooler is mounted as external or full internal mounting.
The supplied drilling template must be used to fasten
the cooling unit on the enclosure or the operating
housing.
The drilling template provides dimension lines for the
various installation options of the cooling unit.
Identify appropriate lines and dimensions on the
drilling template for the required mounting type
(external or full internal mounting) using figures 6
and 7.
Drill the required holes for fastening the cooling unit
and then cut the required cut-out, including the line
width, in accordance with the drilling template.
The direct incidence of cold air on temperature-sensitive components must be
avoided!
Components with integrated fans
determine the cooling air routing in the
enclosure or operating housing.
The mounting position of the cooling unit
must be chosen so that the cooling air flow
supports the heat dissipation of these components.
A free space of at least 100 mm is required
in front of the air inlet and outlet openings of
the cooling unit in the internal and external
circuit.
The cooling unit must be positioned on
the enclosure so that the condensate discharge opening is located at the lowest
point of the cooling unit.
Risk of injury!
Wear protective gear (safety glasses,
protective gloves) when cutting the
mounting cut-out and drilling the
fastening holes.
Carefully deburr all drilled holes and
cut-outs to prevent injuries caused by
sharp edges.

8 Filter mounting
The Rittal Thermoelectric Cooler can be equipped
with a device filter (supplied).
An appropriate filter unit is recommended when the
cooling unit is used in ambient air subject to dust.
When a filter is installed, the lower louvred grille in
the air inlet of the cooling unit must be removed. To
do this, raise the louvred grille with a light tug at the
marked position (see Figure 14) and withdraw it at
the front. Then place the filter mat in the filter holder
of the device. The colour-marked side of the filter mat
must face the device. Then re-mount the louvred
grille and snap it into position by applying light pressure.
Fig. 14: Removable louvred grille
9 Mounting the
condensate discharge
The Rittal Thermoelectric Cooler is equipped with
a condensate discharge.
Fig. 15: Condensate discharge
The controlled condensate discharge requires a
condensate discharge hose be connected to the
cooling unit’s condensate discharge supports.
The condensate hose is available as accessory.
The installation of the condensate hose requires
that it
– is laid with a gradient (no siphon formation),
– does not have any kinks,
– must not have a reduced cross-section if extended.
Note:
When a filter unit is used, it must be cleaned
regularly or, if necessary, replaced.
Risk of injury!
The operation of the cooling unit without
controlled condensate discharge can
cause liquid to accumulate below the
device.

13 Commissioning
GB
13 Commissioning
The Rittal Thermoelectric Cooler is operational immediately after connection of the power supply. If the
factory setting is unchanged, the temperature control of the enclosure or operating housing uses the
following parameters:
Set enclosure interior temperature: +35°C
Start temperature for cooling operation: +35°C
Overtemperature alarm message: +45°C
Under normal operating conditions, device operation with unchanged factory setting should ensure a
problem-free enclosure climate control. If it would
appear to be useful to change the predefined parameters for special climate control requirements,
this can be realised with programming software. In
this case, please contact the device manufacturer.
14 Status and function displays
The Rittal Thermoelectric Cooler is equipped with
a status and function display. Two coloured LEDs

GB
16 Maintenance and cleaning
16.1 Maintenance
The Rittal Thermoelectric Cooler is low-maintenance.
16.2 Cleaning
If the Rittal Thermoelectric Cooler is used in ambient
air subject to dust, dust can accumulate in the area
of the air inlet and outlet openings and on the heat
transferring surfaces of the Peltier element. This can
cause a reduction of the air flow in the device and
thus a gradually reducing cooling capacity. To remove the dust, withdraw the louvred grille at the device front side. Blow compressed air through the air
inlet and outlet openings of the cooling unit.
If the Peltier cooling unit is equipped with a device
filter, it must be cleaned or replaced regularly. The
filter mat can be cleaned by washing, dusting or
blowing with compressed air. The high-quality filter
material used for the mat means the cleaning does
not impair the filter-technical properties and the form
stability. The fire class remains unchanged!
Danger!
Prior to any cleaning or maintenance
work, the power to the cooling unit must
be disconnected!
Note:
When the filter is replaced, use only filter
materials approved for the Rittal Thermoelectric Cooler.
The dust collecting efficiency and dust
storage capacity of the filter equipment
chosen is matched to the rated flow speed
of the cooling unit in the external air circuit
and so guarantees an excellent dust
filtering for a high useful cooling output.

19 Guarantee
Provided the unit is used correctly (refer to the
operating instructions), Rittal gives its customers
a 24-month “Rittal manufacturer’s guarantee”
starting with date of manufacture.
If, within the guarantee period, during the 24 months
after manufacture, a malfunction occurs on the product that substantially adversely affects its functionality, Rittal will, within a reasonable period of time, rectify the malfunction by telephone service or, if necessary, by replacement, repair or other measures, at its
option. If this is inappropriate for the customer, Rittal
also has the possibility to provide the customer with
the replacement parts required to correct the malfunction.
Within the scope of its guarantee, Rittal will bear all
costs concerning the dispatching, deployment and
accommodation of its staff and with replacing or repairing any parts, provided the malfunction occurred
during the proper usage of the products and provided the costs are not increased by the movement of
the products to a place other than that where they
were originally delivered. In addition, Rittal will bear
the necessary costs for procuring and delivering the
replacement parts to the place where the products
were originally delivered.
Any parts delivered for or in replacement will be new
or in mint condition and in a fully functional state free
of faults; the replaced parts will become Rittal’s
property; the customer warrants that no rights of any
third parties will obstruct that exchange and transfer
of title.
Any claims based on this guarantee are to be submitted to Rittal in writing within one month after the
occurrence of the malfunction.
Any further claims, in particular claims for damages
,
are not covered by the guarantee. The statutory liability for defects is not affected by the guarantee.
