4. Electrical connection
The connection voltage and frequency must cor-
respond to the rated values quoted on the data
plate. The unit must be connected to the mains
via a disconnection device which ensures at least
3 mm contact opening in the deactivated state.
No additional temperature control must be con-
nected to the supply side of the unit. Line protec-
tion should be provided by means of the pre-fuse
specified on the name plate. Please observe the
relevant regulations when installing!
The mains connection is made at the connec-
tion terminal (see fig. on page 32).
5. Cooling water
connection
The cooling water connection must be made with
pressure resistant flexible hoses which should be
secured with clips.
(Note the direction of flow and check for
absence of leaks!)
The units have no separate air-bleed. With
pressure-sealed systems, corresponding air-
bleed facilities are to be installed on the water
side.
Protect the water circuit from contamination and
excess pressure (10 bar max.).
Please observe the relevant regulations when
installing!
6. Refrigeration and
control behaviour
The fan of the air circuit operates continuously,
thus ensuring an even temperature distribution
within the enclosure. A solenoid valve controls the
cooling water flow in accordance with the preset
temperature. Setting range +20°C to +60°C.
Presetting of the enclosure temperature is made,
6.1 for SK 3214.100 / SK 3215.100 /
SK 3216.xxx / SK 3217.100 / SK 3218.xxx
via the thermostat on the rear of the unit.
6.2 for SK 3247.000 at the setting knob of the
built-in thermostat. To do this, remove the
hood of the unit.
6.3 for SK 3219.100 / SK 3249.xxx at the
potentiometer P1 of the control board.
To do this, remove the hood of the unit and
the board cover.
6.4 SK 3212.xxx has no control unit.
7. Leaks and temperature
monitoring
7.1 Temperature monitoring
Should the temperature inside the enclosure rise
by more than
10 K in the models SK 3247.000 / SK 3214.100 /
SK 3215.100 / SK 3216.xxx /
SK 3217.100 / SK 3218.xxx
7 K in the models SK 3219.100 / SK 3249.xxx
above the set-point value, then the potential-free
changeover contact will switch. This contact is
routed to the outside via a separate cable for
model SK 3247.000, via a separate plug for
model SK 3219.100 / SK 3249.xxx.
For SK 3214.100 / SK 3215.100 / SK 3216.xxx /
SK 3217.100 / SK 3218.xxx the connection of
the potential-free contact is made via the plug-in
terminal strip on the rear of the unit.
7.2 Leak monitoring

1. Application
Air/water heat exchangers are designed and
built to dissipate heat from enclosures, by cool-
ing the air inside the enclosure and protecting
temperature sensitive components. Air/water
heat exchangers are particularly suitable for the
temperature range of +40°C to +70°C, where for
system related reasons, comparable units such
as air/air heat exchangers, enclosure cooling
units or fan units with filters cannot be used to
dissipate heat effectively and economically.
2. Technical data
(see table 2.1).
3. Assembly
Please use the enclosed drilling template to cut
out the component apertures.
3.1 SK 3247.000
The unit can be mounted
a) on the enclosure
see fig. on page 30
b) inside the enclosure
see fig. on page 30
Cut the enclosed seal to length and stick to the
appliance as shown in fig. 3.2, page 31.
3.2 SK 3219.100 / SK 3249.xxx
The unit should be mounted on the top cover
of the enclosure in accordance with fig. on
page 31.

SK 3212.230 / SK 3214.100 / SK 3215.100 /
SK 3216.xxx / SK 3217.100 / SK 3218.xxx
External installation of the unit (Fig. page 30):
Screw the four fastening bolts ➀, together with
the washer ➁and nut ➂, to the mounting level
➃of the enclosure. Push the heat exchanger ➄
into position and secure with four screws ➅.
Internal installation of the unit (Fig. page 30):
Insert four fastening bolts ➀into the appliance
from behind. Slide the fixing ring ➆onto the
fastening bolts as a mounting aid. Screw the
appliance, together with the washer ➁and nut
➂, to the mounting level of the enclosure from
the outside. Push the protective cap ➇onto the
nut.

10. Notes on discharge
of condensate
A drain hose must be fitted to the 1/2˝ flanged
socket protruding from the unit, to discharge any
condensate water accumulating.
For SK 3219.100 / SK 3249.xxx connect drain
hoses with elbow sockets (do not kink!) and direct
immediately downwards to avoid reflux and over-
flow of the condensate into the inside of the unit.
Fig. 10.1 Condensate discharge
SK 3219.100 / SK 3249.xxx
In order to ensure the safe discharge of conden-
sate, the following points must be observed:
●Discharge hose must be routed free from kinks!
●Do not reduce the hose cross-section!
●Always install the drainage hose with a
downward slope!
In order to prevent increased development of con-
densate and also in the interest of energy savings,
the cooling water temperature should be matched
to the required cooling output (see performance
diagrams).
11. Safety instructions
●When installing the device, the condensate
discharge must be routed out of the enclosure!
●In order to avoid frost damage, the minimum
permissible water temperature of +1°C must
not be undercut at any point in the water cycle!
●It is essential to obtain the manufacturer’s
permission before adding anti-freeze!
●During storage and transportation below
freezing point, the water cycle should be
drained completely using compressed air!
●Only set the thermostat as low as is strictly
necessary, because of undercutting the dew
point with a falling water inlet temperature
(condensation)!
●It is very important that the enclosure is sealed
on all sides (IP 54), particularly the cable entry
(condensation)!
12. Notes on water quality
For safe operation of the equipment, it is essential
to observe the VBG guidelines on cooling water
(VGB R 455 P).
Cooling water must not contain any limescale
deposits or loose debris; in other words, it should
have a low level of hardness, particularly a low
level of carbon hardness. For recooling within the
plant, the carbon hardness should not be too
high. On the other hand, however, the water
should not be so soft that it attacks the operating
materials. When recooling the cooling water, the
salt content should not be allowed to increase
excessively due to the evaporation of large
quantities of water, since electrical conductivity
increases as the concentration of dissolved sub-
stances rises, and the water thereby becomes
more corrosive. For this reason, not only is it
always necessary to add a corresponding quan-
tity of fresh water, but also to remove part of the
enriched water.
Gypsiferous water is unsuitable for cooling pur-
poses because it has a tendency to form boiler
scale, which is particularly difficult to remove.
Furthermore, cooling water should be free from
iron and manganese, because otherwise de-
posits may occur which settle in the pipes and
block them. At best, organic substances should
only be present in small quantities, because
otherwise sludge deposits and microbiological
contamination may occur.
12.1 Preparation and maintenance
of the water in recooling systems
Depending on the type of installation to be
cooled, certain requirements are placed on the
cooling water with respect to purity. According
to the level of contamination and the size and
design of the recooling systems, a suitable
process is used to prepare and/or maintain the
water. The most common types of contamination
and most frequently used techniques to elimin-
ate them in industrial cooling are:
Contamination of the water Procedure
Mechanical contamination
Filtering of water via
– Mesh filter
– Gravel filter
– Cartridge filter
– Precoated filter
Excessive hardness Water softening via ion exchange
Moderate content of mechanical contaminants
and hardeners Addition of stabilisers and/or dispersing agents to the water
Moderate content of chemical contaminants Addition of passifiers and/or inhibitors
to the water
Biological contaminants, slime bacteria and algae Addition of biocides to the water
In order to ensure correct operation of a recooling
system which is operated with water on at least
one side, the properties of the added or system
