3 Transport and storage
Only transport the product inside the original packaging or a
suitable alternative.
The equipment must be protected from moisture and heat
when not in use. They must be stored in a covered, dry and
dust-free room at a temperature between -20 °C to 50 °C (-4 °F
to 122 °F).

4 Installation and connection

4.1 Installation site requirements

This unit is solely intended for wall-mounting in enclosed
areas. Frost protection must be used in temperatures below
0 °C (32 °F).
Install the unit leaving enough room below the cooler to dis-
charge the condensate. This space also ensures unobstructed
airflow/convention. Leave room above for the gas supply. We
recommend mounting at the same height, preferably hori-
zontal to the gas cooler.
Be sure to maintain the approved ambient temperature. En-
sure adequate ventilation when installing in enclosed hous-
ings, e.g. analyser cabinets. If the convection is inadequate, we
recommend aerating the cabinet or installing a fan to lower
the inside temperature.
DANGER
Use in explosive areas
The equipment is not suitable for use in explosive areas.
4.2 Installation
Mount the angles to the wall using the included screws and
ensure the surface meets the requirements and the M3 plug
will not be exposed to mechanical shock. Pay attention to ac-
cessibility during operation and maintenance. Run the gas
supply to the precooler with a downward slope.
If a large amount of condensate accumulates, we recommend
using a condensate trap with automatic condensate drain up-
stream from the cooler. Our condensate drains AK 20 or AK 5.5
are suitable for this purpose.
Glass vessels and automatic condensate drains are available
for draining condensate for external mounting below the
unit. When using automatic condensate drains, the sample
gas pump must be installed ahead of the cooler (pressure op-
eration) to ensure proper function of the condensate drain.
If the sample gas pump is located at the cooler outlet (suction
operation), we recommend using glass condensate traps or
peristaltic pumps.
Connecting the condensate drains
Depending on the material, build a connecting line with fit-
tings and tubing or hose between the heat exchanger and
condensate drain. With respect to hoses, the condensate drain
must be secured separately using a clamp.
The condensate drain can be mounted directly to the heat ex-
changer.
Condensate lines must always be installed with a downward
slope and a minimum inside diameter of 6 mm (1/4").
BX450029 ◦ 02/2020
Attention: Using the emission measurement requires a con-
densate drain and a line made exclusively from chemical-res-
istant materials or using a peristaltic pump. Stainless steel
condensate drains are not recommended for this purpose!
4.2.1 Connecting heat exchanger gas connections
Please note the correct position of the seal 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.

Installing the heat exchanger without acid meter:
The included heat exchanger must be installed in the ventila-
tion base body using the supporting ring. On heat exchangers
without dosing the gas inlet is marked red and the gas outlet
black. The third, unmarked connection is sealed off with a
dummy seal.
Installing the heat exchanger with acid meter:
For heat exchangers with dosing the gas inlet is marked red
and the gas outlet black. The inlet for the acid meter is un-
marked. Be sure to push the acid supply as far into the middle
of the heat exchanger as possible to ensure even distribution
of the acid supply across all glass beads.
4.2.2 Connecting the peristaltic pump (accessory)
If a heat exchanger was also ordered, install this in the ventil-
ation base body and connect it to the peristaltic pump.
The ø6 connection for the pump's condensate output must be
carefully and properly connected with a suitable hose and
hose clamp.

Installing peristaltic pumps CPsingle / CPdouble limits the
maximum permissible operating pressure in the system!
