TC-MIDI (+) X2
The operator of the system must ensure:
• Safety notices and operating instructions are available
and observed,
• 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,
• compliance with national installation regulations.
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 maintenance. Wear appropriate pro-
tective equipment.
DANGER

Explosion hazard

Life and explosion risk may result from gas leakage due to im-
proper use.
a) Use the devices only as described in this manual.
b) Regard the process conditions.
c) Check tubes and hoses for leakage.
WARNING
Risk of breakage
a) Protect the equipment against being hit.
b) Protect the device against falling objects.
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. It must be stored in a covered, dry and dust-
free room at a temperature of -20 °C to 60 °C (-4 °F to 140 °F).

4 Installation and connection

4.1 Installation site requirements

The unit is only intended for wall-mounted use in enclosed
areas. Adequate protection from the weather must be
provided when used outdoors.
Install the unit leaving enough room below the cooler to dis-
charge 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 espe-
cially 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 inad-
equate, we recommend 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 V38, AK 20, AK 5.5 OR AK 5.2, 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
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. 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 ex-
changer.
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.
4.2.1 Connecting the filter gas connections (optional)
The connection between the heat exchanger outlet and the fil-
ter inlet already has tubing. The connection G1/4 or NPT
1/4" (filter head marked NPT) for the gas outlet must be care-
fully and properly connected using a suitable screw connec-
tion.
When ordering the cooler with the option filter without Mois-
ture detector, a bypass may be connected to the filter head.
