– The respective national accident prevention regulations are observed,
– The permissible data and operational conditions are maintained,
– Safety guards are used and mandatory maintenance is performed,
– Legal regulations are observed during disposal.
Maintenance, Repair
Please note during maintenance and repairs:
– Repairs to the unit must be performed by Bühler authorised personnel.
– Only perform conversion-, maintenance or installation work described in these operating and installation instructions.
– Always use genuine spare parts.
Always observe the applicable safety and operating regulations in the respective country of use when performing any type of
maintenance.
DANGER Electrical voltage
Electrocution hazard.
a) Disconnect the device from power supply.
b) Make sure that the equipment cannot be reconnected to mains unintentionally.
c) The device must be opened by trained staff only.
d) Regard correct mains voltage.
DANGER Toxic, corrosive gas/condensate
Sample gas/condensate may be hazardous to health.
a) If necessary, ensure a safe gas/condensate discharge.
b) Always disconnect the gas supply when performing maintenance or repairs.
c) Protect yourself from toxic/corrosive gasses/condensate when performing mainten-
ance. Wear appropriate protective equipment.

3 Transport and storage
The product should only be transported inside the original packaging or a suitable alternative.
When not in use, the equipment must be protected from moisture and heat. They must be stored in a covered, dry and dust-free
room at a temperature between -20 °C and 60 °C.

4 Installation and connection
4.1 Installation site requirements
The unit is only intended for use in enclosed areas in a 19” rack or wall-mounted. Adequate protection from the weather must be
provided when used outdoors.
Install the unit leaving enough room below the cooler to discharge the condensate. Leave room above for the gas supply.
Be sure to maintain the approved ambient temperature. Do not obstruct the convection of the cooler. The vents must have
enough room to the next obstacle. The distance must especially be a minimum of 10 cm on the air outlet side.
Ensure adequate ventilation when installing in enclosed housings, e.g. analyser cabinets. If the convection is inadequate, we re-
commend aerating the cabinet or installing a fan to lower the inside temperature.
4.2 Installation
Run the gas supply to the cooler with a downward slope. The gas inputs are marked in red and additionally labelled "IN".
If a large amount of condensate accumulates, we recommend using a condensate trap with automatic condensate drain. Our
condensate drains, 11 LD spec., AK 20 V, or model 165 SS, are suitable.
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 upstream of the cooler (pressure operation)
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 peri-
staltic pumps.
Connecting the condensate drains
Depending on the material, build a connecting line with fittings and tubing or hose between the heat exchanger and condens-
ate drain. For stainless steel the condensate drain can be suspended directly to 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 exchanger.
Condensate lines must always be installed with a slope and a minimum inside diameter of DN 8/10 (5/16”).
4.2.1 Peristaltic pump connector (optional)
Coolers ordered with attached peristaltic pump already have it installed and wired. Heat exchangers ordered at the same time
are already installed and connected 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.
NOTICE
Installing peristaltic pumps CPsingle / CPdouble limits the maximum permissible oper-
ating pressure in the system!
Operating pressure ≤ 1 bar
