4.2.2 Flow adapter connection (optional)
When ordering the cooler with the option moisture detector
without filter, it will be factory installed inside a flow adapter.
The connection between the heat exchanger outlet and the
flow adapter inlet does not have tubing included. The connec-
tion G1/4 or NPT 1/4" (flow adapter marked NPT) for the gas
inlet/outlet must be carefully and properly connected using a
suitable screw connection. Here the direction of flow is not
relevant.
4.2.3 Connecting the moisture detector (option)
When ordering the cooler with moisture detector option, it
will be factory installed inside a flow adapter, or for the filter
option installed and connected in the filter head.
4.2.4 Peristaltic pump connector (optional)
Coolers ordered with built-in peristaltic pumps already have
these installed and wired. Heat exchangers ordered at the
same time are already installed and connected to the peri-
staltic pumps.
NOTICE
Installing peristaltic pumps CPsingle / CPdouble limits the
maximum permissible operating pressure in the system!
Operating pressure ≤ 1 bar
A peristaltic pump may also be installed away from the cooler.
A mounting angle is available for mounting the pump directly
below the cooler. Mounts for securing the angle directly to the
cooler are designated.
4.2.5 Connecting the heat exchanger
The gas inputs are marked in red.
On glass heat exchangers the correct position of the seal is im-
portant when connecting the gas lines (see image). The seal
consists of a silicone ring with a PTFE sleeve. The PTFE side
must face the glass thread.

Pay attention to the appropriate spanner size when selecting
fittings for stainless steel heat exchangers.

4.2.6 Condensate drain connection
Depending on the material, build a connecting line with fit-
tings and tubing or hose between the heat exchanger and
condensate drain. For stainless steel, the condensate drain
can be hung directly from the connecting tube; for hoses, the
condensate drain must be secured separately using a clamp.
The condensate drain can be mounted directly to the heat ex-
changer.
When choosing the option for high-purity oxygen, make sure
to select the suffix -O2.
If the condensate drain 11 LD V 38 is used for high hydrogen
concentrations, the system in which it is installed must be
tested for leaks.
Condensate lines must always be installed with a slope and a
minimum inside diameter of DN 8/10 (5/16").
The DTV heat exchanger cannot be operated in conjunction
with an automatic condensate drain.
4.2.7 Adapter plate connection
The adapter plate is intended to easily replace the cooler with
an existing bore pattern of the predecessor EGK 1/2. It is first
inserted from behind with the threaded bolts through the
bores of the RC 1.x and locked in place with the included nuts.
The cooler with adapter plate can then be fastened to the ex-
isting bore pattern.
4.3 Electrical connections
The operator must install an external separator for the device
which is clearly assigned to this device.
This separator
• must be located near the device,
• must be easy for the operator to reach,
• must comply with IEC 60947-1 and IEC 60947-3,
• must separate all live conductors and the status output,
and
• must not be attached to the power feed.
• the mains supply of the device must be fused according to
the specifications under technical data.
WARNING
Hazardous electrical voltage
The device must be installed by trained staff only.
CAUTION
Wrong mains voltage
Wrong mains voltage may damage the device.
Regard the correct mains voltage as given on the type plate.
WARNING
High voltage
Damage to the device in case of insulation testing
Do not proceed insulation tests with high voltage to the
device as a whole!
